Researchers reach new level of clarity in recording proteins moving through lipids

first_img © 2012 Phys.org (Phys.org) — One of the great challenges in biology is recording biological processes at the cellular or even subcellular level. To get a close view, microscopes have to focus on one specific part of whatever it is they are looking at, but because biological processes generally involve movement; that which they are looking at suddenly moves out of the frame. Now it appears a team of international researchers led by Simon Scheuring of Parc Scientifique et Technologique de Luminy, has found a way to record the “dance” that goes on as membrane proteins diffuse within biological membranes. The team describes their technique in their paper published in the journal Nature Nanotechnology. In order for biology to work at the subcellular level, proteins, lipids and sugars along with other molecules have to follow certain rules, which some have likened to dance steps, because some of the most basic rules involve the paring up of molecules. This paring up allows the molecules to carry out activities that cannot be done alone. Also, one of the things that need to happen to sustain life is for proteins to somehow make their way through a layer of lipids, as is the case with Escherichia coli which have an outer membrane coated with proteins that need to make their way inside.To actually watch the dance that goes on as the proteins try to make their way through the membrane, the researchers built a new kind of microscope apparatus. It involves a stylus, a cantilever and a laser. The tip or stylus of the apparatus moves slowly over the surface of the specimen being studied while the laser serves as a guide. The cantilever allows the stylus to bob up and down in concert with the hills and valleys found below. What this does is allow a camera to record the cellular terrain in similar fashion to a helicopter moving up and down as it surveys a mountain range, trying to maintain the same altitude throughout. By doing so, recordings can be made of very small biological processes as they occur.Using this setup, the team was able to record in minute detail the pairing up of molecules and note the way those that weren’t able to pair up made their way through the outer membrane of the E. coli bacteria. The team believes this new technology will open the door to much more research by many teams investigating how biological processes at the subcellular level actually work.

The functions of these membrane proteins depend on their position and also on protein–protein and protein–lipid interactions. However, so far, it has not been possible to study simultaneously the structure and dynamics of biological membranes. Here, we show that the motion of unlabelled membrane proteins can be characterized using high-speed atomic force microscopy. We find that the molecules of outer membrane protein F (OmpF) are widely distributed in the membrane as a result of diffusion-limited aggregation, and while the overall protein motion scales roughly with the local density of proteins in the membrane, individual protein molecules can also diffuse freely or become trapped by protein–protein interactions. Using these measurements, and the results of molecular dynamics simulations, we determine an interaction potential map and an interaction pathway for a membrane protein, which should provide new insights into the connection between the structures of individual proteins and the structures and dynamics of supramolecular membranes.

Researchers show RNA ribozymes able to cooperate to reassemble themselves

first_img More information: Spontaneous network formation among cooperative RNA replicators, Nature (2012) doi:10.1038/nature11549AbstractThe origins of life on Earth required the establishment of self-replicating chemical systems capable of maintaining and evolving biological information. In an RNA world, single self-replicating RNAs would have faced the extreme challenge of possessing a mutation rate low enough both to sustain their own information and to compete successfully against molecular parasites with limited evolvability. Thus theoretical analyses suggest that networks of interacting molecules were more likely to develop and sustain life-like behaviour. Here we show that mixtures of RNA fragments that self-assemble into self-replicating ribozymes spontaneously form cooperative catalytic cycles and networks. We find that a specific three-membered network has highly cooperative growth dynamics. When such cooperative networks are competed directly against selfish autocatalytic cycles, the former grow faster, indicating an intrinsic ability of RNA populations to evolve greater complexity through cooperation. We can observe the evolvability of networks through in vitro selection. Our experiments highlight the advantages of cooperative behaviour even at the molecular stages of nascent life. Study builds on plausible scenario for origin of life on Earth (Phys.org)—A team of chemistry and applied sciences researchers from several universities in the United States has shown that RNA fragments torn apart in the lab work together to reassemble themselves. This finding, the team claims in their paper published in the journal Nature suggests that early life may have started with cooperative efforts between RNA molecules eventually leading to cooperative replication.

Journal information: Nature The team based its work on mathematical theories proposed by Manfred Eigen, a chemist who suggested that because early RNA wouldn’t be able to successfully evolve from short stranded molecules, they must have had help. That help, he said, may have come in the form of cooperative efforts between molecules.In earlier work team lead Niles Lehman had found that if long RNA molecules known as ribozymes were cut into fragments and then placed together in a Petri dish, they would over time reassemble themselves into their original configuration. In this new research, Lehman et al altered three ribozyme samples so that they were identical save for one letter that allowed for distinguishing among them. Each was cut into two pieces and placed in a Petri dish. The team found that if the ribozymes were placed together in a Petri dish, they reassembled themselves faster than if they were put in the dish alone. This occurred, they report, because one of the ribozymes helped another reassemble, who then helped a third reassemble who in turn helped the first reassemble, which formed a closed loop network.To see if the same result might be possible in a more chaotic environment, the researchers placed 48 cut ribozymenes in a test tube with millions of other RNA molecules and found that the original 48 found a way to locate their other parts and each other and helped one another reassemble; again much faster than any of them would have alone.The team suggests that a similar type of cooperation among short RNA molecules in Earth’s primordial soup may have allowed them to replicate in a way that avoided the problem of building up mistakes when making copies that mathematical models have suggested would have led to evolutionary death. That would have allowed them to evolve into longer more complex RNA molecules and eventually into all the other molecules that exist today. © 2012 Phys.org Explore further Citation: Researchers show RNA ribozymes able to cooperate to reassemble themselves (2012, October 18) retrieved 18 August 2019 from https://phys.org/news/2012-10-rna-ribozymes-cooperate-reassemble.htmllast_img read more

Physics at the threshold of hearing

first_imgHair Cells. Credit: fmhs.uaeu.ac.ae Arnold Tongue. Credit: Wikipedia Commons The main results of the study were based on observations of the time evolution of the phase difference between that of the hair bundle, and that of the stimulus. They show that the system exhibits what is known in the business as a “staircase” function. The staircase structure in the phase difference is a classic signature of mode locking in a dynamical system. The authors suggest that better understanding of the effect of weak signals on spontaneous oscillations in hair cells will shed light on other phenomena, like otoacoustic emissions. These emissions are measured spontaneously in newborns—in other words, in the absence of any sound stimulus. When measured in response to a stimulus, they reliably indicate that the hearing system in a child too young to talk is intact. In tinnitus, a faulty feedback system and magnified otoacoustic emissions are often to blame. While complex at times, the application of techniques from physics to biology continues to give rewarding insight into how sensory systems operate at the threshold of noise. It’s not over when it’s over: Storing sounds in the inner ear More information: Phase Slips in Oscillatory Hair Bundles, Phys. Rev. Lett. 110, 148103 (2013) DOI: 10.1103/PhysRevLett.110.148103AbstractHair cells of the inner ear contain an active amplifier that allows them to detect extremely weak signals. As one of the manifestations of an active process, spontaneous oscillations arise in fluid immersed hair bundles of in vitro preparations of selected auditory and vestibular organs. We measure the phase-locking dynamics of oscillatory bundles exposed to low-amplitude sinusoidal signals, a transition that can be described by a saddle-node bifurcation on an invariant circle. The transition is characterized by the occurrence of phase slips, at a rate that is dependent on the amplitude and detuning of the applied drive. The resultant staircase structure in the phase of the oscillation can be described by the stochastic Adler equation, which reproduces the statistics of phase slip production. Citation: Physics at the threshold of hearing (2013, April 10) retrieved 18 August 2019 from https://phys.org/news/2013-04-physics-threshold.html Before the mammalian state of the art evolved, animal sound systems relied on a single kind of hair cell to do it all. For that reason, scientists often use the large hair cells from the sacculus of a bullfrog for their research. By studying this low frequency auditory and vestibular organ, scientists get a first-hand look at the precursors of the mammalian inner-outer hair cell system. They have found that when these hair bundles are dissociated into a single-cell preparation, they spontaneously exhibit mechanical vibrations. These vibrations can be up to 100nm in amplitude, and require sustained energy in the form of ATP. Compared to the total length of a cell, 100nm is not huge, but it appears to be sufficient to modulate the inner-ear detection machinery. These hair cell oscillations can be driven by a sinusoidally varying stimulus, at least within a certain amplitude and frequency range. Other researchers have shown that the spontaneous oscillations of the hair cells could be described by equations that show a Hopf bifurcation. We don’t talk about Hopf bifurcations every day at Phys.org, however they do pop up in the description of dynamical systems from time to time. For example, in describing the periodicity of the heart, equations that possess a Hopf bifurcation can reveal how a system changes from a stable state to an oscillatory state. (Please see Periodic heart rate deceleration’s in premature infants for further description of this.) Near a critical Hopf point in the dynamical description of the hair cells, a low-amplitude driving stimulus can produce a high-amplitude mechanical response. At the risk of losing the attention of a few readers, we want to impose here one more mathematical animal from the bestiary of dynamical systems—the Arnold tongue. The accompanying picture shows what an Arnold Tongue looks like in a phase space portrait. Bozovic’s group was previously able to show that the phase-locked responses of hair bundles to a broad range of driving stimuli exhibited an Arnold Tongue. In their new Physical Review Letters paper, they were additionally able to show that hair bundle motion can be described by the Adler equation. This equation is commonly is used to analyze phase locking in oscillatory systems. © 2013 Phys.org (Phys.org) —The mammalian auditory system is one of the most sensitive detectors found in nature. Two kinds of cells, the inner and outer hair cells, work together to transduce mechanical vibrations into action potentials. Sound energy is detected and transmitted by the inner hair cells, while properties like gain and frequency selectivity, are controlled by the mechanical adjustments of vibrating outer hair cells. The business end of these cells, known as the hair bundle, is composed of 30 or more stereocilia, that serve as the transducers. To date, physiologists are at odds to explain how the hair bundle can respond to mechanical stimuli whose energy is an order of magnitude below the energy level of the background thermal motion. A new study from Dolores Bozovic’s lab at UCLA takes theoretical look at the mechanical vibrations of hair cells. Their analysis, recently published in Physical Review Letters, does not close the book on the noise-busting capabilities of the hair cell system, but it does provide a framework to qualitatively describe their motion, and extend current models of their behavior. Journal information: Physical Review Letters The group collected their data by imaging single hair bundles with a high-speed CMOS camera, and they delivered stimuli through a glass fiber. Typically, at least in mammalian outer cells, vibrations are studied by electrically stimulating the cells. Outer hair cells can remain phase locked to stimuli up to several thousand hertz. At these frequencies, electrical excitation can be delivered more practically and uniformly. The bullfrog succulus, as noted above, typically operates in the more familiar, low-frequency regime. The authors report they used a stimulus amplitude of 1.7 nm, suggesting they may be using direct mechanical stimulation here. They further report the stimulus corresponds to a force of around 0.4pN, suggesting models of the mechanical properties of cell may have been used to interpret the stimulus more flexibly.

Physicists find that entanglement concentration is irreversible in contrast with previous research

first_img Citation: Physicists find that entanglement concentration is irreversible, in contrast with previous research (2013, October 7) retrieved 18 August 2019 from https://phys.org/news/2013-10-physicists-entanglement-irreversible-contrast-previous.html This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. (Phys.org) —Several different types of entangled states can be used in quantum information processes, and these states can be converted into one another using a variety of conversion processes. While previous research has suggested that one of the most common types of conversions, called entanglement concentration, is reversible, a new paper shows for the first time that it is irreversible due to a trade-off relation between performance and reversibility. The finding could have implications for future developments in quantum information applications. Journal information: Physical Review Letters © 2013 Phys.org. All rights reserved. A diagram of entanglement concentration and its recovery operation, entanglement dilution. Scientists have found that an initial entangled state cannot be completely recovered after the concentration process. Credit: Kumagai, et al. ©2013 American Physical Society “The irreversibility of entanglement concentration seems similar to the fact that from-concentrate fruit juice is slightly different from the original juice,” Hayashi said, since one process is used to remove water from the juice and another process used to do the opposite. “Commonly, both concentration processes lose a subtle essence from the original.”For practical purposes, this irreversibility means that some of the initial copies of the entangled pure state cannot be recovered from the entangled EPR state. The physicists calculated the minimal concentration-recovery error (MCRE)—which is a combination of both errors—that gives the maximum number of recoverable copies under different circumstances. This formulation could be applied to a variety of quantum information processes.”Our result shows not only the impossibility of the perfect recovery of the entanglement concentration, but also provides the optimal designs of the entanglement concentration and the recovery operation,” Hayashi said. “This design may be used for a better realization of quantum storage of entangled states.”As Hayashi explained, this finding builds on his previous research on irreversibility with respect to data compression.”Many researchers in the information theory community believed that compressed data up to the Shannon limit is the perfect random number, which is called ‘the folklore of source coding,” he said. “However, this is not true. In this problem, we considered the decoding error probability of the data compression and the difference of the compressed data from the perfect random number. In 2004, I found the trade-off between the decoding error probability and the difference. Then, I showed that the sum goes to 1 when the size of data goes to infinity.”Although this idea is not well-known in the information community, it inspired the researchers to investigated entanglement concentration irreversibility.In the future, the researchers plan to use these results to clone entangled states. This cloning is closely related to the irreversibility of entanglement concentration, since the key point of the cloning is the evaluation of error of the recovery operation.”Now, we consider applying our idea to the cloning of entangled states when a number of copies of a given entangled state are prepared,” Hayashi said. “In fact, if we are not allowed to use global quantum operations between distinct parties, i.e., we are allowed to use only local operation and classical communication (LOCC), we cannot increase the amount of entanglement.”Hence, in this case, even if we know the wave function of the entangled state, we cannot clone the entangled state (i.e., increase the number of copies) without any error. However, if we accept a small size of error, there is a possibility to increase the number of copies. We named this operation the LOCC cloning, which is our current research topic.” The physicists, Wataru Kumagai at Tohoku University in Sendai, Japan, and Nagoya University in Nagoya, Japan; and Masahito Hayashi at Nagoya University and the National University of Singapore, have published their paper on the irreversibility of entanglement concentration in a recent issue of Physical Review Letters.In quantum information processes, entanglement concentration is used to convert multiple copies of an entangled pure state into multiple copies of an entangled EPR state. Another conversion process, called entanglement dilution, does the opposite; that is, it converts copies of the EPR state into copies of a pure state. Due in part to the fact that the optimal rates of entanglement concentration and entanglement dilution are the same, physicists have previously thought that entanglement concentration may be reversible. If this were true, reversible entanglement concentration could be used to compress multiple copies of an entangled pure state in a lower dimensional storage system, and later the initial state could be recovered using entanglement dilution.However, in the current paper the researchers have examined the recovery process more deeply, and have found that it doesn’t quite work this way. The physicists explain that the recovery process has two kinds of errors: a concentration error, which represents performance; and a minimum recovery error, which represents the degree of irreversibility.Complete success occurs when an error is zero, while complete failure occurs when an error is 1. The physicists show that each error can individually attain the value zero, but not at the same time. This happens because of a trade-off between the concentration error and the minimum recovery error. The sum of both errors must always be 1, so that the smaller one error is, the larger the other becomes.This trade-off implies that, when the concentration error is 0, the minimum recovery error is 1. That is, perfect entanglement concentration is completely irreversible. The researchers describe this irreversibility using an analogy to another type of concentration: concentrated fruit juice.

Age and ageing

first_imgBeing a widow, and with all her four daughters married, she has learnt to live life on her own. Whether going out to enjoy a sunny day or to a hospital for treatment, there is nobody to take care of her except God, she says. “I have learn to live alone. I use to sit and wait in queues for medicine or for appointment with doctor. Though it is tiring but I had no option. Despite separate queues for elderly, it gets difficult at times,” said Maya Devi.Diagnosed with Tuberculosis a while back, even her immune system has betrayed her. For quite sometime, her life has succumbed to the hospital bed. She is getting treated at All India Institute of Medical Sciences (AIIMS), in a well developed geriatric ward, supposedly the only one in the city.Though our Prime Minister Narendra Modi banks on the young population to take the country on high road, the fact is by 2050 India would have 324 million populace above 60 years of age. The current aged populace, which is estimated to be around 83 million, one third live below poverty line and 75 per cent reside in rural areas, further limiting their access to healthcare facilities.“Despite a countrywide alarm, geriatrics is still an alien field in our country. The concept of geriatric usefulness has not yet set in our country. Also, there is negligence towards this field from medical professionals too,” said Anupama Datta, Director of Policy Research and Development, HelpAge India.Although there are government and social policies for elderly in India, but geriatrics is relatively a new field of medicine. “Post graduation in Geriatrics was introduced in 2011. They are not many seats reserved for this course. In main centres, there are nine seats, out of which four are in AIIMS, three in Madras medical college, one in medical institute in Kochi and Vellore respectively,” said A B Dey, professor and head of department of geriatrics at AIIMS. Geriatrics or geriatric medicine is a specialty that focuses on healthcare of elderly people. It differs from standard medicine as it focuses on unique needs of elderly and especially, managing multiple morbidities.“Body of the elderly is different physiologically than young.  Generally, they have multiple morbidities. They may simultaneously have osteoarthritis, depression, visual impairment, nutritional deficiency and such. In absence of geriatric care, an elderly person has to go to different specialist for treating their various ailments. Also, at the age of 60 and above, the patient doesn’t have the energy to run to different specialist. In geriatrics,  the aim is to give comprehensive health care to elderly and help in healthy ageing,” said A B Dey.If trends are to be noted, not many young aspiring doctors wants to opt for geriatrics. “Not many young doctors are interested in pursuing this course because many have misconceptions that it is not a proper medical field. Every doctor wants to become a surgeon,” said Dey.Some who opt for it, say they are into this field by ‘chance.’ “Geriatrics was not my first choice. Since, I did not have many options, so I opted for it. I had doubts about the course but now I think I accidentally got the right thing. In this field, workload is less, elderly want to be heard more than cured,” said a geriatric resident at AIIMS.The most recent policy effort is the National Policy for Health Care of the Elderly (NPHCE), released in 2011. As per the policy, eight super speciality institutions catering to development of geriatrics would be developed in different regions. The programme also included provision of establishing 10 bedded geriatric wards and dedicated Out Patient Department (OPDs) in 100 districts covering 21 states/UTs.“City hospitals have geriatric clinics which are operational on particular days and also, preference to elderly is given. In our hospital, there is no specific geriatric ward. We have 100 bedded hospital in which around 20 beds are allocated for specialities. So, it is difficult to set up a geriatric ward. But we do witness many elderly seeking treatment,” said S K Sharma, medical superintendent at Aruna Asaf Ali Government Hospital.Even if geriatric wards are established in district hospitals, another challenge that lies ahead is accessibility and awareness. “I visited a geriatric ward in one of the hospitals in Rajasthan. Most elderly complained that it was not useful for them. People are unaware of what is geriatric or why it’s needed for them. Most elders live with the attitude that at old age, they are bound to suffer with diseases that do not have any cure. With old age comes a negative connotation in our society,” said Anupama Datta.‘Besides awareness, public facilities are cumbersome. Elderly often are unable to access it. Especially, elderly women from lower income group are more prone to it. Elder abuse is on rise but actions are far and few’, she added.While government healthcare sector is lacking behind in geriatric care services, even the private sector has not shown much interest in the field. “There is no expressed demand. There is no trained manpower in the field or scientific assessment of its need. There is biasness towards young people. Even if private sector opens geriatric wards, how many will be able to access them?,” said Datta.According to recent data, visual impairment and vision loss increases dramatically with age. Overall 10 per cent of India’s elderly suffers from depression; 50 per cent require psychological interventions at some point. “Because of weak immune system there chances of reoccurrence of diseases like tuberculosis and such. Many people also develop TB at this age. Dementia, chronic obstructive airways diseases, hypertension, heart diseases, diabetes are some of the common diseases that elders suffer from,” said a doctor at AIIMS.AIIMS, which has a separate geriatric ward, caters to 150 patients on daily basis. “The hospital alone cannot be expected to take the load. Pressure has to be built at state and community level.Government needs to prioritise elderly issues. They should also be given employment so they can contribute to the overall GDP of the country,” said Anupama Datta.last_img read more

Corporate espionage Court seeks MoPNGs report on leaked docs

first_imgThe direction came during arguments on the bail pleas of five corporate executives, who along with others, were arrested in connection with the case, with the court asking the police as to how it has arrested the accused without ascertaining whether the documents were classified or not.During the hearing, an Assistant Commissioner of Police (ACP) of Crime Branch told the court that they were yet to receive a report from the Ministry on its query if the documents allegedly leaked were classified or confidential. “It is directed that the report (of MoPNG) be submitted in three days. Put up for further hearing on April 10,” Additional Sessions Judge Raj Kapoor said. Also Read – Company director arrested for swindling Rs 345 croreThe court also asked the investigating officer (IO) to show the letter they had written to the MoPNG for evaluation and analysis to specify whether the documents allegedly leaked were confidential and classified or were routine papers.During the hearing, the court asked the IO about the nature of documents recovered from the accused and whether these were classified. Responding to this, the IO said “the documents recovered from the accused are being verified as of now and the ministry is analysing and evaluating the documents, but Crime Branch have not yet received any reply from them.” Also Read – Man who cheated 20 women on matrimonial websites arrestedNot satisfied with the IO’s reply, the judge said, “You have not charged the accused under the Official Secrets Act (OSA) till now. Then how have you arrested them without even ascertaining that the documents were classified?” At this juncture, the court directed the IO to call the ACP and posted the matter for hearing in the afternoon.ACP K P S Malhotra appeared before the court and informed the judge that the Crime branch has written to the Ministry on March 11 and a committee has been formed to evaluate the documents. During the hearing, the court perused the documents placed before it by the police and said, “Do you (ACP) know the repercussion if these documents go into public domain. This is a very serious matter.” The court posted the bail pleas for further hearing on April 10 and directed the ACP to expedite the matter with the Petroleum Ministry. Five corporate executives — Shailesh Saxena of Reliance Industries Ltd, Vinay Kumar of Essar, Subhash Chandra from Jubilant Energy, Reliance ADAG DGM Rishi Anand and Cairns India’s GM K K Naik, have moved fresh bail pleas after their earlier pleas were dismissed by Chief Metropolitan Magistrate (CMM) Sanjay Khanagwal on March 24. On February 20, police had arrested the five accused corporate executives alleging that they used to procure the classified documents from other arrested accused Lalta Prasad and Rakesh, and used to pay them.The documents were then supplied to the firms by these officials for their benefit, the police had alleged.On February 25, Virender Kumar, a Defence Ministry staff member, was arrested in the case. Besides them, the police had also arrested Rakesh Kumar, Prayas Jain, Shantanu Saikia, Ishwar Singh, Asharam and Rajkumar Chaubey, who are also in judicial custody.last_img read more

The Rose Bowl was a classic but neither Penn State or USC

first_imgLast night’s Rose bowl classic between Penn State and USC proved that both teams can play with anybody. This morning, people are lamenting the fact that Penn State and USC were excluded by the College Football Playoff committee. Colin sees this as a predictable knee jerk reaction to a great game, but it doesn’t change his opinion that conference champions shouldn’t automatically get in the playoff, and bad losses, like USC and Penn State both have, shouldn’t be ignored by the selection committee.“That was one of the best college football games I’ve seen in my life. It’s in my Top 5.”The other story coming out of the Rose Bowl is that USC quarterback Sam Darnold looks like a future NFL franchise quarterback. With Darnold, Colin sees intangibles that jump off the charts. Last night, Darnold put on one of the all-time great performances by a college football quarterback in a big game. Darnold looks like he has the potential to be the best Trojan signal caller in the history of the program, by a lot.“I think he’s the best quarterback I’ve ever seen at USC.”Nick Saban took an unprecedented step of relieving Lane Kiffin from his duties as offensive coordinator before the national championship game against Clemson. Colin says this move was not a knee jerk reaction by Saban, because he doesn’t do knee jerk.Saban clearly had an axe to grind with Kiffin, whom he berated on the sidelines during blowout wins, and disrespected at press conferences throughout the year. Only Saban knows the actual reason, but this was calculated to make Kiffin look bad. There’s no question about it.“I think it was Saban’s way to punish Lane Kiffin, for whatever reason it is.”Guests:Clay Travis  – Founder of Outkick the Coverage joins the show to discuss the USC/Penn State Rose bowl thriller, explain why he thinks both teams should have been in the playoff, why both teams will be favorites to make the playoff next year, and why USC quarterback Sam Darnold is a transcendent talent.Eric Mangini – Former Browns and Jets head coach is in-studio to discuss Lane Kiffin being let go by Alabama, which NFL coaching opening he thinks is the best, why any coaching opening without a quarterback is set up to fail, and if the Patriots could trade Tom Brady this offseason.Peter Schrager – Fox Sports NFL Insider joins the show to discuss the controversy in New York over Odell Beckham and the Giants’ receivers partying all night on South Beach, where the 49’ers could go with their coach and GM search, if Kyle Shanahan could be a fit in Denver, and if Sean Payton could still end up in L.A.Chris Broussard – FS1 NBA Insider joins the show to explain what LeBron needs to do to surpass MJ, if the Lakers need to move off D’Angelo Russell, if they have the pieces to pull off a trade for a superstar, and why Mike D’Antoni is the NBA coach of the year so far.Clay Helton – USC Head Football Coach joins the show to discuss his team’s thrilling Rose Bowl win over Penn State, his thoughts on Freshman superstar quarterback Sam Darnold, if he’s slept yet, and his appreciation for the history of the two programs.last_img read more

Social Media Con Artists a Rising Problem

first_img As people increasingly turn to the web to make connections and build relationships, more entrepreneurs see business opportunities in online social networking. But if you decide to create an online community, you also should be prepared to protect your users from scammers and spammers.Fraudulent activity on social networking sites can range from relatively harmless, albeit annoying, spam messages to potentially dangerous scams. A spam email message may be sent to thousands of people on a social network directing them to another website to possibly sell something, often pornography. In online scams, a con artist often sets up a fake profile, develops a relationship with an innocent victim, and then tries to convince that person to wire him or her money.The North American Securities Administrators Association, an investor protection organization, has seen serious fraud in online networks, including a Craigslist post for a “stock trading program” that promised 100 percent returns monthly and a dating site scam involving the sale of worthless gold certificates from Ghana.Online profiles provide fertile ground for con artists. “The person behind the profile may be deliberately mimicking your likes and interests to lure you into a scam,” David Massey, president of the association, said in a statement. “A con artist can take advantage of how easily people share background and personal information online by using this information to make a highly targeted pitch.”Related: What’s With All the Interest in Pinterest?Dating companies, in particular, frequently deal with spam and scams. Online fraud-management company iovation found that 3.8 percent of all of the “transactions” it processed on online dating sites last year were fraudulent, more than double the 1.4 percent rate in 2010 and 1.5 percent in 2009. Transactions in this case include any online abusive activity that iovation tracks, including hijacked accounts, scams, chat room abuses, fake profiles and spam.Keeping the number of fraudulent profiles to a minimum in the online dating industry is a constant battle. “It is like an arms race. The spammers get better at what they are doing, they learn about the chinks in the armor, and the dating sites react,” says David Evans, editor of Online Dating Insider, a blog covering the business of online dating.  It’s tempting to think that a scam would be obvious. But scammers “are trained criminals; they know how to gain people’s trust,” says John Breyault, vice president of public policy, telecommunications and fraud at the National Consumers League. “The criminals that perpetrate this fraud are very good at manipulating people’s emotions and ultimately getting them to send money.”Scams can be detrimental to a dating website’s reputation, in particular. “To acquire a reputation where bad things happen to their users is arguably one of the worst things that can happen to their brand,” says Breyault.Related: How to Avoid One of the Biggest Email Hacking ThreatsThe problems grow more complex as a social network attracts more users. That has certainly been the case for HowAboutWe.com, a Brooklyn, N.Y.-based online dating site. As the site grew, its product development team and technology engineers worked together to develop a multi-tier defense program to keep spam to a minimum.First, a computer algorithm identifies triggers the dating site deems suspicious behavior. That could include a certain type of IP address, the frequency of messages sent, or a combination of words, says Brian Schechter, a co-founder of HowAboutWe. Any profile that gets flagged by the computer algorithm gets temporarily held in a “pen,” while a staff member manually reviews it for any suspicious behavior. When a profile is being held, the user can send messages, but others won’t receive them until the staff has approved the flagged profile and pushed it back out of the pen.Schechter recommends that other entrepreneurs react quickly when they suspect a scam. “Take it really seriously because if you don’t, you are sort of allowing a virus to go unchecked,” he says. “And if you let that happen, the health of the ecosystem you are creating is in jeopardy.”Michelle Breyer, the co-founder of NaturallyCurly.com, depends on the members of her loyal online community to help her police the site’s discussion forum, CurlTalk.Photo courtesy of Margarita CorporanSome entrepreneurs with social networking platforms also rely on loyal users to help police the site. When Michelle Breyer launched NaturallyCurly.com as a forum for people with curly hair 14 years ago, the online discussion board CurlTalk attracted some fraudulent users who posted links to try to sell products or drive traffic to pornography sites.Breyer first installed a filter that requires users to type in cursive letters that a visitor would read. That made it much harder for spammers to send mass emails. She also listened to her community of curly-haired chatters. They pointed out suspicious-looking discussion threads, using the site’s “report problems” link. “We have amazing members who help us self-police,” Breyer says.Related: Three Tips for Keeping Business Data Safe on Personal Mobile Devices”The discussion board was really the dynamic area of the site and that was really what got people to the site,” she adds. “If people don’t feel comfortable coming to a place for whatever reason–whether it is spam, mean people, people selling to them–you are going to lose the community.”Certainly, it’s good business to try to protect your customers from scams, but it also is becoming legally necessary for dating sites in some states. New York and New Jersey have already passed legislation called the “Internet Dating Safety Act.” Protections there range from notifying users about whether a dating site has performed background checks on customers to requiring sites to recommend safety precautions to users, says Caitlin Moldvay, the author of an IBISWorld report on the online dating industry.Other states, including California, Florida, Michigan, Texas, Illinois and Connecticut, have proposed regulations, some of which would require dating sites to perform background checks. Such legislation would make it more expensive to operate dating sites, but the safeguards could boost business by offering customers a sense of protection.  6 min read Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global Register Now »center_img Growing a business sometimes requires thinking outside the box.

Would You Enroll in an Accelerator Put On By Zynga

first_img Attend this free webinar and learn how you can maximize efficiency while getting the most critical things done right. October 16, 2013 Zynga is making headlines again, but instead of news about its struggles, the attention is on its nonprofit arm, Zynga.org.Last night, the gaming company that created FarmVille, along with NewSchools Venture Fund, showcased its first class of startups for its brand new ed-tech accelerator co.lab.For its part, Zynga will pony up $1 million for the accelerator’s first year and provide mentorship with employees, including sharing insights on design, marketing and distribution. The company has also allowed the accelerator program to be hosted at Zynga’s San Francisco headquarters.”We’re excited to lend not just space, but, we hope, other talents at Zynga,” founder and former CEO Mark Pincus said to the crowd last night. “I think there’s already been an outpouring of interest from Zynga employees to get involved. Hopefully they don’t join the companies permanently, but if that happens, we’ll live with it.”Related: Five Keys to Building a Successful Gaming Company While the program was announced in May and the five startups have been busy at the accelerator since September, this was the first time the companies got to show off their work. The five businesses currently at co.lab include: LocoMotive Labs: An educational app for children with special needs. Motion Math: Apps involving games for children revolved around numbers and challenges Kidaptive: The company behind Leo’s Pad, a storytelling app for preschoolers. Pluto Media: Music apps for children Edmodo: Distributor of games and online educational tools.Related: An Interview With Zynga.com (Video) Broadening its horizons beyond mind-numbing games like FarmVille 2, may be a smart move for the struggling company. Anyone with an ear to the ground in tech has heard about Zynga struggles — from the poaching shenanigans to the fallout of OMGPop’s acquisition to the never ending layoffs and departures, the company could use positive publicity. And they just might get it with co.lab. Free Webinar | Sept 5: Tips and Tools for Making Progress Toward Important Goalscenter_img 2 min read Register Now »last_img read more

Sochi Organizers Did a Terrible Job Stocking Olympic Souvenirs

first_img This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience. Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now February 14, 2014 Enroll Now for Freecenter_img 2 min read While spectators have converged on Sochi from far and wide to witness this year’s Olympics, many will be leaving the Games without so much as a lousy T-shirt.Organizers grossly underestimated merchandising opportunities — with just one superstore on Olympic Park premises and only a handful of other stands throughout that are surprisingly nondescript, reports The Wall Street Journal.The sole superstore, operated by Russian retailer and chief Sochi licensee Bosco di Ciliegi, counts waits outside of up to two hours, and visitors are grumbling about a paltry offering and steep prices.One Russian customer balked to The Journal about a children’s jacket priced at almost $700.Related: 10 Things I Learned While Training for the Olympics That Absolutely Apply to BusinessEven Bosco itself admits to the miscalculation. “We definitely underestimated the interest in this during the Games, and in Russia generally,” the retailer’s vice president of marketing, Olga Chernosvitova, told The Journal.Sochi’s organizing committee is forecasting roughly $30 million in revenue from 55 total partners and an assortment of 5,000 different products. The London Olympics in 2012, by comparison, generated more than four times as much — $130 million from 10,000 licensed items.While Russia spent an estimated $51 billion on infrastructure, its licensing business is relatively underdeveloped — and culturally, Russians are less apt to seek out souvenirs, Chernosvitova said.And ironically, a large majority of sales are taking place far from the Olympic hub. A superstore more than 1,000 miles away in Moscow is accounting for half of all Bosco sales, while Sochi revenues represent just 15 percent of overall sales, The Journal noted.Related: 3 Social Media Lessons from the Olympicslast_img read more

GM Open to Working With Google on Developing SelfDriving Cars

first_img General Motors is open to working with Google on developing self-driving car technology, the chief technology officer for the U.S. automaker said on Monday.“I’m not in charge of deciding what we will and won’t do, but I’d say we’d certainly be open to having a discussion with them,” Jon Lauckner said in an interview at the Detroit auto show.Lauckner made his comments two days before the head of Google’s self-driving car project, Chris Urmson, is scheduled to speak at a conference held annually in conjunction with the auto show. Urmson is expected to announce his company’s plans to seek partnerships within the auto industry.Self-driving cars have been a hot topic for both companies in recent months. GM CEO Mary Barra made headlines in the fall when she said that some GM cars would have limited driverless tech, such as the ability to detect pedestrians, by 2017. She also announced that GM would be part of the team building 120 miles of so-called “autonomous” highway — roads with sensors that enable communication between cars — around Detroit.And Google’s driverless car ambitions are well-known. Just last month, the Silicon Valley giant unveiled the first fully-functioning prototype of a driverless car. This model doesn’t really look like any car you’ve seen on the road, and certainly doesn’t look like something GM would produce — it looks more like something you’d see in a 1960s science fiction movie.Combining these two perspectives and histories — GM’s ability to make cars that people actually want to buy with Google’s ability to innovate and push the technology envelope — could make a lot of sense in terms of ushering in the future of autonomous cars. Just how an arrangement might work, though, is a question.“You have to figure out how would something like that actually work,” Lauckner said. “Would it be something where it would be an opportunity to work together in a joint development agreement?”—Reuters contributed to this report.

The First Net Neutrality Complaint Looks Doomed to Fail

first_img Net neutrality has been the law of the land for only 10 days, but already a web-cam company is knocking on the FCC’s door to complain that Time Warner Cable is breaking the rules. The case could, in theory, lead the agency to flex new powers over an internet provider – but the smart money will bet that the FCC throws the web-cam firm out on its ear.The complaint, which came to light on Monday, comes via Commercial Network Services (CNS), a San Diego company that live-streams views of southern California. It asks the FCC to do something about the fact that Time Warner Cable wants to charge it for delivering its web traffic. Because CNS won’t pay, its live stream is choppy and slow.“Aha!” some might say, “Isn’t this what net neutrality is supposed to prevent?”Not quite. The dispute here doesn’t involve the so-called “last mile” where ISP’s like Time Warner Cable bring broadband to consumers – and where the FCC has made it clear that all web traffic must be treated the same. Instead, the CNS case involves “peering” or “interconnection,” which refers to a type of connection that occur at a deeper layer of the internet, and takes place between content providers (like Netflix or CNS) and the ISPs.In these cases, the FCC only requires for arrangements between ISP’s and the websites providing content to be reasonable. So is Time Warner Cable being unreasonable? Well, that’s for the FCC to decide but, according to a gaggle of people who live and breathe this stuff, the ISP is not obliged to serve CNS for free, and its complaint will fail.CNS’s chances seem especially faint because those predictions are coming from folks on all sides of the net neutrality debate. Harold Feld, a lawyer for Public Knowledge a supporter of the new FCC rules, says on his blog that Time Warner Cable does not appear to have treated CNS any differently than it treats other websites, so its behavior is not unreasonable.Meanwhile, industry analyst and net neutrality skeptic Dan Rayburn tells Vice, which has a thorough rundown on the issue, that CNS will fail. Finally, Karl Bode of DSLReports sums it up this way:“‘We deserve free peering just because’ isn’t likely to cross the FCC’s threshold for an argument that constitutes a valid anti-competitive complaint.”The legal case, in other words, appears to be hopeless. The only real question here is how, if at all, this first test case will affect the larger brouhaha that is still swirling around net neutrality. Some Republicans have been hellbent on ripping up the FCC rules, and are even threatening to tie their repeal to the budget process, so it’s always possible this case could be used as political ammunition – whatever its outcome.

This Bike Headset Warns About Traffic Behind You

first_img There are already bike-friendly smart headsets that will tell you how you’re doing, but they won’t usually say much about traffic. How are you supposed to know when a car is getting uncomfortably close?That’s where Garmin thinks it can help. As part of a larger CES launch, it’s unveiling a Varia Vision headset that not only gives you vital cycling data (directions, notifications and performance), but teams up with the Varia rearview radar to warn about traffic behind you. You’ll know about trouble right away without losing focus, in other words. It won’t be cheap when it ships this quarter for $400, but it could be justifiable if you regularly bike on busy streets.If you’re more interested in sports tracking on your wrists than your head, you’re also covered today. The Fenix 3 watch is getting on-the-wrist heart rate monitoring in an $800 HR model, extra sports profiles (for golf and rowing) as well as options for new models with sapphire lenses that cost $600 in normal trim, and $800 with a titanium finish. There’s also a new variant of the rugged Tactix watch, the $600 Bravo, that can track everything from high-altitude parachute drops to advanced running. All of these wearables should arrive sometime in the first quarter of the year.Drivers are getting some upgrades as well. Garmin is kicking out four Drive GPS units that warn you about conditions that other mapping devices miss, such as sharp turns, crossings and even fatigue. The line starts at $130 with the basic Drive. The DriveSmart introduces a link to your smartphone for notifications, live traffic and weather, while the DriveAssist includes a dash cam to both document and prevent crashes. Splurge on the $350 DriveLuxe and you’ll get “HD” traffic avoidance that warns you as quickly as 30 seconds. These, too, should show up in the first quarter.Oh, and there’s one more thing: Garmin is introducing Connect Insights to help make sense of that flood of information. The features will study your sleep, predict your step count and otherwise make sure that you’re hitting your activity goals. The Insights will launch in January, and you can expect more of them throughout the year.Image Credit: GarminImage Credit: GarminImage Credit: GarminImage Credit: GarminImage Credit: GarminImage Credit: GarminImage Credit: GarminImage Credit: Garmin Register Now » This story originally appeared on Engadget 2 min read January 5, 2016 Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global Growing a business sometimes requires thinking outside the box.last_img read more
