The huge amounts of energy released would appear as spherical, low-variance radiation bursts in the CMB. Image credit: Gurzadyan and Penrose. Planck Satellite ready to measure the Big Bang (PhysOrg.com) — In general, asking what happened before the Big Bang is not really considered a science question. According to Big Bang theory, time did not even exist before this point roughly 13.7 billion years ago. But now, Oxford University physicist Roger Penrose and Vahe Gurzadyan from the Yerevan Physics Institute in Armenia have found an effect in the cosmic microwave background (CMB) that allows them to “see through” the Big Bang into what came before. The CMB is the radiation that exists everywhere in the universe, thought to be left over from when the universe was only 300,000 years old. In the early 1990s, scientists discovered that the CMB temperature has anisotropies, meaning that the temperature fluctuates at the level of about 1 part in 100,000. These fluctuations provide one of the strongest pieces of observational evidence for the Big Bang theory, since the tiny fluctuations are thought to have grown into the large-scale structures we see today. Importantly, these fluctuations are considered to be random due to the period of inflation that is thought to have occurred in the fraction of a second after the Big Bang, which made the radiation nearly uniform.However, Penrose and Gurzadyan have now discovered concentric circles within the CMB in which the temperature variation is much lower than expected, implying that CMB anisotropies are not completely random. The scientists think that these circles stem from the results of collisions between supermassive black holes that released huge, mostly isotropic bursts of energy. The bursts have much more energy than the normal local variations in temperature. The strange part is that the scientists calculated that some of the larger of these nearly isotropic circles must have occurred before the time of the Big Bang.The discovery doesn’t suggest that there wasn’t a Big Bang – rather, it supports the idea that there could have been many of them. The scientists explain that the CMB circles support the possibility that we live in a cyclic universe, in which the end of one “aeon” or universe triggers another Big Bang that starts another aeon, and the process repeats indefinitely. The black hole encounters that caused the circles likely occurred within the later stages of the aeon right before ours, according to the scientists.In the past, Penrose has investigated cyclic cosmology models because he has noticed another shortcoming of the much more widely accepted inflationary theory: it cannot explain why there was such low entropy at the beginning of the universe. The low entropy state (or high degree of order) was essential for making complex matter possible. The cyclic cosmology idea is that, when a universe expands to its full extent, black holes will evaporate and all the information they contain will somehow vanish, removing entropy from the universe. At this point, a new aeon with a low entropy state will begin. Because of the great significance of these little circles, the scientists will do further work to confirm their existence and see which models can best explain them. Already, Penrose and Gurzadyan used data from two experiments – WMAP and BOOMERanG98 – to detect the circles and eliminate the possibility of an instrumental cause for the effects. But even if the circles really do stem from sources in a pre-Big Bang era, cyclic cosmology may not offer the best explanation for them. Among its challenges, cyclic cosmology still needs to explain the vast shift of scale between aeons, as well as why it requires all particles to lose their mass at some point in the future.

NASA unveils possible submarine design for exploring liquid methane seas on Titan

first_imgNASA expects some sort of sub might be ready for a journey to Titan by 2040, which would mark the first time such a mission has not been conducted on dry land. To get it there, they envision a winged craft that makes its way to the surface, then sinks beneath the waves on Kraken Mare, leaving the sub to discover what lies beneath. Explore further (Phys.org)—NASA has unveiled at this year’s Innovative Advanced Concepts (NIAC) Symposium (and posted a video on Youtube) a possible design for a submersible robot for use in exploring the liquid methane/ethane seas on Saturn’s moon Titan. The video and sub design were created by NASA Glenn’s COMPASS Team along with some researchers from Applied Research Lab. The call for the design came from workers with the NASA NIAC Program, which of course is tasked with coming up with ideas for new ways to explore space and the celestial bodies in it. 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. The sub, which the team has dubbed the Titan Submarine Phase I Conceptual Design, looks reminiscent of early subs on Earth such as those developed for use in the Civil War. The technology onboard, would be anything but old, of course, as it would have to be able to operate mostly autonomously in a very hostile and distant environment.The most likely place for deployment of the sub would be Kraken Mare—Titan’s largest polar sea. Data from probes has found that the sea covers approximately 154,000 square miles with depths as deep as 525 feet. The sea is not idle, either—it has currents and a tide, both of which could make keeping the sub safe from harm a serious challenge. There would also be the problem of communicating with it. The researchers envision a system where the sub surfaces for 16 hours at a time, sending signals directly to Earth (which would take almost an hour and a half to get here). As an undersea vehicle, it would not be able to use solar power either, so the team envisions a radiothermal Stirling generator for propulsion. Also, because of the extreme cold, a special piston driven type of system would have to be developed to prevent freezing of (likely nitrogen) ballast. Though it is still not clear exactly what the sub might be looking for, one sure bet is it would be searching for compounds that might indicate life once existed in the sea or perhaps offer clues as to how life began back here on Earth.

Electrical circuit made of gel can repair itself

first_img More information: Ye Shi, et al. “A Conductive Self-Healing Hybrid Gel Enabled by Metal-Ligand Supramolecule and Nanostructured Conductive Polymer.” Nano Letters. DOI: 10.1021/acs.nanolett.5b03069 Shape-shifting gels get smarter The researchers, led by Guihua Yu, an assistant professor at the University of Texas at Austin, have published a paper on the new self-healing gel in a recent issue of Nano Letters.The new gel’s properties arise from its hybrid composition of two gels: a supramolecular gel, or ‘supergel’, is injected into a conductive polymer hydrogel matrix. As the researchers explain, this “guest-to-host” strategy allows the chemical and physical features of each component to be combined. The supergel, or the “guest,” provides the self-healing ability due to its supramolecular chemistry. As a supramolecular assembly, it consists of large molecular subunits rather than individual molecules. Due to its large size and structure, the assembly is held together by much weaker interactions than normal molecules, and these interactions can also be reversible. This reversibility is what gives the supergel its ability to act like a “dynamic glue” and reassemble itself. Meanwhile, the conductive polymer hydrogel, or the “host,” contributes to the conductivity due to its nanostructured 3D network that promotes electron transport. As the backbone of the hybrid gel, the hydrogel component also reinforces its strength and elasticity. When the supergel is injected into the hydrogel matrix, it wraps around the hydrogel in such a way as to form a second network, further strengthening the hybrid gel as a whole.In their experiments, the researchers fabricated thin films of the hybrid gel on flexible plastic substrates to test their electrical properties. The tests showed that the conductivity is among the highest values of conductive hybrid gels, and is maintained due to the self-healing property even after repeated bending and stretching. The researchers also demonstrated that, when an electrical circuit made of the hybrid gel is cut, it takes about one minute for the circuit to self-heal and recover its original conductivity. The gel self-heals even after being cut multiple times in the same location.The researchers explained that the conductive self-healing material has a variety of potential applications.”The conductive self-healing gel we developed can be applied in many technologic areas, from flexible/stretchable electronics, artificial skins, energy storage and conversion devices, to biomedical devices,” Yu told Phys.org. “For example, the gel can be potentially used in implantable biosensors as flexible yet self-healable electrodes, ensuring the durability of these devices. And in energy devices, for example, the gel can function as binder materials for advanced battery electrodes in high-density Li-ion batteries where high-capacity electrodes may experience substantial volume changes.”The researchers also hope that, by combining supramolecular chemistry and polymer nanoscience, the resulting hybrid gels may provide a useful strategy for designing new self-healing materials.”We are planning to investigate the fundamental mechanisms of the self-healing properties of supramolecular gels and to better understand how different key factors, such as different metal ions, the molecules’ geometries, and the interactions between the supramolecule and different solvents, affect the self-healing characteristics,” Yu said. “A deeper fundamental understanding will allow better materials to be developed. Meanwhile, from a more ‘practical applications’ standpoint, some research efforts (together with our collaborators) will be devoted to developing scalable synthetic strategies of supramolecules and self-healing hybrid gels with even better mechanical strength and elasticity, for potential applications of these self-healing gels in different technology areas.” Explore further Citation: Electrical circuit made of gel can repair itself (2015, August 25) retrieved 18 August 2019 from https://phys.org/news/2015-08-electrical-circuit-gel.html (a) After being cut in half, the conductive supergel self-heals and can support its own weight when lifted with tweezers.

Jadavpur Vidyapith turns turbulent over lottery admission to Class V

first_imgKolkata: The guardians of Jadavpur Vidyapith students staged a sit-in demonstration on Tuesday, protesting against the admission of students in Class V through lottery system.A notification issued by the school authorities has triggered confusion among some of the parents, who put up a road block in front of the school on Tuesday morning. The agitation was later lifted after the intervention of senior police officers, who urged the guardians to stop the demonstration. Also Read – Rain batters Kolkata, cripples normal lifeEarlier, the students studying in the primary or Kishalaya section of the school had been able to take direct admission to Class V. On last Friday, the school authorities had published a notice saying that the lottery system which is applied for selecting students in the Kishalaya section, would also be implemented for the admission of students in Class V.The publication of the new notification triggered resentment among the guardians who demanded withdrawal of the notification. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedParents of the students in primary section said that their candidates were given admission through a lottery system. They raised questions on the rationality of implementing the same system for the second time for admission of students in Class V.Parents of some students in Class IV said that there are around 180 seats in class V. “What is the point in introducing a new method when the existing system has been doing well and all the students from the Kishalaya section are getting hassle free admission in Class V?” asked the guardians. If the new system is introduced, a large number of students who are studying in the primary section of the school would not get an opportunity to study in the secondary level.Till last year, all the students from Class IV in the Kishalaya section used to get direct admission to Class V. Outside candidates were given an opportunity to get admission in Class V only after all the Class IV students of the school secured admission in the next class. The guardians said that they have talked to the headmasters of both the primary and higher secondary sections, but no assurances were given by the school authorities. After this, many guardians started demonstration inside the school campus from 7 am on Tuesday. Some others later joined the agitation.Traffic movement was disrupted in the area after the agitating guardians took to the streets. They put up a road block, demanding withdrawal of the new notification.The school authorities said that the direct transfer of a student from Class IV to V is not possible because Jadavpur Vidyapith is a government-aided school, while the primary section is run by private management.last_img read more

Teens as sedentary as 60yearolds

first_imgPhysical activity among children and teens is lower than previously thought, according to a new study which found that 19-year-olds are as sedentary as 60-year-olds. The findings come amid heightened concern that exercise deficits are contributing to the growing obesity epidemic, particularly among children and teens, researchers said.The study by Johns Hopkins Bloomberg School of Public Health in the US found that young adults after the age of 20 show the only increases in activity over the lifespan, and starting at age 35, activity levels declined through midlife and older adulthood. It also identified different times throughout the day when activity was highest and lowest, across age groups and between males and females. Also Read – Add new books to your shelfThese patterns, the researchers said, could inform programmes aimed at increasing physical activity by targeting not only age groups but times with the least activity, such as during the morning for children and adolescents.”Activity levels at the end of adolescence were alarmingly low, and by age 19, they were comparable to 60-year-olds,” said Assistant Professor Vadim Zipunnikov. “For school-age children, the primary window for activity was the afternoon between 2 and 6 pm. So the big question is how do we modify daily schedules, in schools for example, to be more conducive to increasing physical activity?” said Zipunnikov, senior author of the study published in the journal Preventive Medicine. Also Read – Over 2 hours screen time daily will make your kids impulsiveThe researchers used data from the US National Health and Nutrition Examination Survey from the 2003-2004 and 2005-2006 survey cycles. The 12,529 participants wore tracking devices for seven straight days, removing them for only bathing and at bedtime. The devices measured how much time participants were sedentary or engaged in light or moderate-to-vigorous physical activity.Activity among 20-somethings, the only age group that saw an increase in activity levels, was spread out throughout the day, with an increase in physical activity in the early morning, compared to younger adolescents, researchers said. The increase may be related to starting full-time work and other life transitions. For all age groups, males generally had higher activity levels than females, particularly high-intensity activity, but after midlife, these levels dropped off sharply compared to females. Among adults 60 years and older, males were more sedentary and had lower light-intensity activity levels than females.The study confirmed that recommended guidelines were not being met. For instance, the World Health Organisation recommends at least 60 minutes of moderate-to-vigorous physical activity a day for children aged five to 17 years. The study found that more than 25 per cent of boys and 50 per cent of girls aged six to 11 and over 50 per cent of male and 75 per cent of female adolescents aged 12 to 19 had not met the WHO recommendation.last_img read more

CID grills Bharati Ghosh again over Daspur case

first_imgKolkata: Former IPS officer Bharati Ghosh was interrogated by the state Criminal Investigation Department (CID) on Friday.Sources informed that CID had served a notice at her Naktala home in Kolkata but Ghosh was not there. Her husband MAV Raju refused to receive the notice. Later, Ghosh informed CID that she was not able to attend the call as she was busy with election-related work. Following her intimation on Thursday, a CID team went to her home at Daspur in West Midnapore.

The apex court also directed Ghosh to intimate the state about her contact number and whereabouts. Also Read – Lightning kills 8, injures 16 in stateOn Friday afternoon, a team from CID went to Ghosh’s rented house in Daspur. She was interrogated in connection with the extortion case lodged against her at the Daspur police station. However, CID officials did not disclose anything regarding the interrogation as it may hamper the investigation process. Earlier during March this year, Ghosh was granted protection from arrest by the Supreme Court. Following the stay on her arrest, Ghosh appeared before the Midnapore District Court, responding to a summon in connection with the Daspur extortion case. CID raids were started following a case of extortion and criminal conspiracy which was initiated in West Midnapore’s Daspur during February last year after gold trader Chandan Majhi lodged a complaint against some police officers in the district, who were reportedly close to the former SP Ghosh. The sleuths had earlier seized more than Rs 2.4 crore in cash and several important government documents while raiding a number of flats in an apartment at Kolkata’s Madurdaha. A huge amount of unaccounted cash was also seized from the house of several police officers named in the FIR. Ghosh’s husband Raju was also arrested last year in this connection.last_img read more

Disguises effective in identity deception

first_imgSuperficial but deliberate changes in someone’s facial appearance – such as a new hairstyle or complexion – are surprisingly effective in identity deception, a study suggests. Researchers at the universities of York and Huddersfield in the UK found that participants were often fooled by disguises when asked to judge whether two photographs showed the same or different people. The study, published in the Journal of Experimental Psychology: Applied, found that evasion disguise is much more effective than impersonation disguise. Also Read – Add new books to your shelfDisguises reduced the ability of participants to match faces by around 30 per cent, even when they were warned that some of the people had changed the way they look, researchers said. Participants were only able to see through disguises reliably when they knew the people in the images. “We should not be complacent about deliberate disguise in criminal and security settings. When someone puts their mind to concealing their identity, it can be very effective,” said Rob Jenkins from the University of York. Also Read – Over 2 hours screen time daily will make your kids impulsive”Familiarity with the people who are disguising themselves improves accuracy. When you are unfamiliar with a face you are easily fooled by superficial changes in hairstyle or colouration,” said Jenkins. “However, when you ‘know’ a face you tend to rely more on internal facial features which are much harder to alter,” he said. The models recruited for the study were given plenty of time and resources with which to change their appearance. Many used make-up, changed their hair colour and style, and some grew or got rid of facial hair. Props like hats or dark glasses were not allowed as they are prohibited in real-life security settings.The researchers also compared the effectiveness of two different methods of disguise. Impersonation disguise – or trying to look like someone else – is sometimes used by people attempting to travel using a stolen passport or in cases of identity theft. Evasion disguise – trying not to look like yourself – might be used in witness protection programmes or by undercover police, as well as by criminal suspects on the run from the law. “With evasion disguise, you can change your appearance in any way you like,” said Eilidh Noyes. “With impersonation, you can only change your appearance in ways that resemble your target, so your options are much more constrained,” Noyes said. “Deliberate disguise poses a real challenge to human face recognition. The next step is to test automatic face recognition on the same tasks,” Noyes said.last_img read more

Infants can judge friends strangers by laughter

first_imgInfants as young as five months can differentiate laughter between friends and between strangers, finds a new study. It has been recently established that co-laughter – or simultaneous laughter between two or more individuals – allows adult listeners across different cultures and languages to quickly evaluate the nature of relationships between people: are they friends, acquaintances, or strangers? The study suggests that the ability to detect this nature of social relationships is instilled early in human infancy, possibly the result of a detection system that uses vocal cues. Also Read – Add new books to your shelf”Infants’ sensitivity to different kinds of laughter might be one of the early emerging tools they use to understand and navigate the complex social world,” said Athena Vouloumanos, Associate Professor from the New York University. “Very brief instances of shared laughter can reveal rich information about people’s relationships, detectable in infants as young as five months of age and universally by adults around the world,” added co-author Gregory Bryant, Professor at University of California-Los Angeles. For the study, published in the Scientific Reports journal, the team examined how five-month-olds processed exchanges of co-laughter of adults – specifically, those who were strangers and those who were friends – by gauging how long they listened to these sounds. The team found that infants could not only differentiate between the laughter of friends and strangers, but, when given the choice, they preferred to listen longer to co-laughter between friends. In another experiment, the team found that infants could tie co-laughter to judgments about human relationships.last_img read more

first_imgFrazier wasn’t done, and added, “There will be an asterisk by [Durant’s] name” for joining the Warriors when it comes to his ranking on the all-time list. Some will agree with Frazier, others will call it old school NBA player hatin’, but Clyde’s opinion isn’t uncommon for the older crowd. Be on the lookout for comments from @KevinDurantFan0087.Knicks HOFer Walt Frazier told me Kevin Durant will be down on the all-time list & have an asterisk next to his name bc he joined the Warriors. pic.twitter.com/ctKRtmtKrz— Justin Termine (@TermineRadio) August 29, 2018 Advertisement Old school NBA’ers criticizing current NBA players as soft is nothing new, and it’s no secret that many older NBA heads had a problem with Kevin Durant opting to join the stacked Warriors in free agency, and an EZ pass to the title podium.Knicks great Walt Frazier is among those that wasn’t a fan of the move, and told Sirius XM’s NBA Today that KD is a great player, but gets points off for joining the stacked Dubs:“Durant, as great a player he is, I would still hold back (giving him credit) because he joined a team that really didn’t need him.“He’s right there with LeBron, probably would’ve surpassed LeBron as the best player in the game soon, but for him doing that I still don’t give him the full credit that he probably would’ve deserved if he stayed in OKC and won a title with that team.”last_img read more

Will Synthetic Biology Evolve Into the Next Hot Field

first_img Synthetic biology grew from a very old human desire to engineer living systems and make them do useful things for us.As genetic engineering of the 1970s has evolved into synthetic biology today, the technologies and economics for sequencing (reading) and synthesizing (writing) DNA have become optimized for large-scale DNA processing. This allows synthetic biologists to design and modify the genetics of living systems so that they produce a wide variety of materials for us that don’t occur in nature, such as drugs, biofuels, flavors, fragrances and more.The field is garnering the attention of entrepreneurs and investors — here are some things you should know that help explain why.1. The growing “Bioeconomy.” Domestic revenues in the U.S. from genetically modified systems are growing faster than the economy as a whole, weighing in at approximately 10 percent annually, according to Rob Carlson, principal at Biodesic and bioeconomic consultant to The White House. The Genetically Modified Domestic Product in 2012 (GMDP) was $350 billion, or roughly 2.5 percent of GDP, up $50 billion from 2010.Related: Entrepreneurs on the Moon, DNA Hacking and Real-Life Iron Man GearThe Woodrow Wilson Centre for International Scholars concluded in its 2013 findings on the growth of synthetic biology that “the number of entities conducting research in synthetic biology increased significantly between 2009 and 2013, resulting in a total of 508 unique entities in the 2013 inventory.” The number of synthetic biology companies has also more than tripled in that timeframe, growing from 61 to 192. Market research shows that the global synthetic biology market was valued at $1.1 billion in 2010 and is expected to reach $10.8 billion by 2016. The market’s expected compound annual growth rate (CAGR) is 45.8 percent.“Although synthetic biology is still in the very early experimental phase, it could become the defining technology of the 21st century,” says Fidelity Investments fixed-income analyst Rob Chan in a video, “bringing with it radical new thinking, new questions and new opportunities, because nothing has the power to change how we live more than changing life itself.”2. The shrinking cost of the sequenced genome. Why the growth? The cost of sequencing DNA has been plummeting since “next generation” sequencers hit the market in 2007. It did so at a rate that far surpassed Moore’s Law — the rule that says computing power doubles and gets cheaper about every two years. However, as Carlson explains on his blog, the most up-to-date data shows that the cost curves are no longer exponentially decreasing. This is likely a healthy reflection of the fact that the companies involved are not losing revenues.Despite the recent gradual slope, the exponential drop in DNA sequencing ushered in projects that would have been laughably ambitious just a few years earlier. The Human Genome Project was a massively expensive undertaking that took place between 1990 and 2003, involving more than 200 scientists and $3 billion to read the roughly 3 billion bases of DNA in each and every one of us. Today, thanks to the drop in sequencing price per base and grant funding from the U.S. National Human Genome Research Institute, the awards for the last round of funding to achieve the $1,000 human genome will be granted this year. It’s not here yet, but it is on its way.3. Increased support from public and private sources. In 2004, the Bill and Melinda Gates foundation helped put synthetic biology on the map when it granted $42 million to the University of California at Berkeley, the Institute for OneWorld Health, and the California-based Amyris Biotechnologies for the research and development of an antimalarial synthetic drug called artemisinin. Ten years later, the UK boldly named synthetic biology as one of the “Eight Great Technologies” that will accelerate economic growth this century and have allocated about $265 million for its development and commercialization.Related: This New Genetics Startup Wants to Make ‘100’ the New ’60’4. The DIY community. Synthetic biology has attracted a community of biohackers, also known as DIY biologists. They work outside of institutional labs and do their experiments in homemade or community labs with the aim to democratize biotechnology. The typical biohacker lab does not receive institutional financing and makes its money through membership fees, donations and classes. Some community labs have received government grants, such as La Paillase in France, which recently expanded to the Philippines and Ireland.Although biohackers are not at all times explicitly working with synthetic biology, they are closely coupled to the synthetic biology community and work flexibly across traditional and emerging biotechnologies.“Biohackers have found extremely creative things to do with the tools they possess,” said Dr. Matthew Bennet, professor of biochemistry and cell biology at Rice University. “I was particularly impressed with the brilliant simplicity of some of their ideas — such as creating [non-synthetic] ‘bio-ink’ (ink for drawing and painting that is naturally produced by bacteria). Those of us in academia would never have thought of that because we are always searching for the next big breakthrough. Now they can take what we have learned in research and dream up novel applications.”Some biohackers are commercializing their applications and creating a cottage industry of their own. For more information, visit diybio.org.5. Opening the field. Bill Liao, investment partner at SOS Ventures, has launched several technology companies. Now Liao is investing in synthetic biology startups by running an accelerator program.“It has become clear that biological technology is going to have its best shot at forward progress by adopting the same protocols of open standardization and the sharing of information and proven computer code,” he said.Liao said he believes that synthetic biology has enormous potential to operate as an open science, which companies such as Synbiota are trying to push forward. As a result, Liao has created the Synbio Axlr8r, a startup accelerator program happening this spring and summer in Cork, Ireland. SOS Ventures will provide seed funding of almost $60,00 to each accepted startup.Related: Next Up in Health Tech: DNA Hacking Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience. 6 min read Opinions expressed by Entrepreneur contributors are their own.

Apple Google Plan Fixes for Newly Uncovered Freak Security Bug

first_img Apple Inc and Google Inc said on Tuesday that they have developed fixes to mitigate the newly uncovered ‘Freak’ security flaw affecting mobile devices and Mac computers.The vulnerability in web encryption technology could enable attackers to spy on communications of users of Apple’s Safari browser and Google Inc’s Android browser, according to researchers who uncovered the flaw.Apple spokesman Ryan James said the computer had developed a software update to remediate the vulnerability, which would be pushed out next week.Google spokeswoman Liz Markman said the company had also developed a patch, which it has provided to partners. She declined to say when users could expect to receive those upgrades.Google typically does not directly push out Android software updates. Instead they are handled by device makers and mobile carriers.The Washington Post reported that the bug left users of Apple and Google devices vulnerable to cyberattack when visiting hundreds of thousands of websites, including Whitehouse.gov, NSA.gov and FBI.gov. http: (wapo.st/18KaxIA)Whitehouse.gov and FBI.gov have been fixed, but NSA.gov remains vulnerable, the paper cited Johns Hopkins cryptographer Matthew D. Green as saying.A group of nine researchers discovered that they could force web browsers to use an form of encryption that was intentionally weakened to comply with U.S. government regulations that ban American companies from exporting the strongest encryption standards, according to the paper.Once they caused the site to use the weaker export encryption standard, they were then able to break the encryption within a few hours. That could allow hackers to steal data and potentially launch attacks on the sites themselves by taking over elements on a page, the newspaper reported.Markman said that Google advises all websites to disable support for the less-secure, export-grade encryption.”Android’s connections to most websites – which include Google sites, and others without export certificates – are not subject to this vulnerability,” she added.The group of researchers dubbed the flaw Freak, for “Factoring RSA-EXPORT Keys,” according to a website where they described the vulnerability.(Reporting by Jim Finkle; Editing by Christian Plumb, Bernard Orr) 2 min read Enroll Now for Free This story originally appeared on Reuters Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience.
