Nasa scientists find evidence of flowing water on Mars
Publish Time: 2015-09-29 20:45:00
Images taken from the Mars orbit show cliffs, and the steep walls of valleys and craters, streaked with summertime flows that in the most active spots combine to form intricate fan-like patterns. Scientists are unsure where the water comes from, but it may rise up from underground ice or salty aquifers, or condense out of the thin Martian atmosphere. “There is liquid water today on the surface of Mars,” Michael Meyer, the lead scientist on Nasa’s Mars exploration programme, told the Guardian. “Because of this, we suspect that it is at least possible to have a habitable environment today.”The water flows could point Nasa and other space agencies towards the most promising sites to find life on Mars, and to landing spots for future human missions where water can be collected from a natural supply. “Mars is not the dry, arid planet that we thought of in the past,” said Nasa’s Jim Green. “Liquid water has been found on Mars.”Some of the earliest missions to Mars revealed a planet with a watery past. Pictures beamed back to Earth in the 1970s showed a surface crossed by dried-up rivers and plains once submerged beneath vast ancient lakes. Earlier this year, Nasa unveiled evidence of an ocean that might have covered half of the planet’s northern hemisphere in the distant past, The Guardian reported.

Invention will help colour blind watch television in more detail
Update Time: 2014-12-08 19:22:02
For colour blind people watching their favourite teams play football, or following a recipe on a cookery programme can be tricky.But that could be about to change, thanks to a new invention by British computer scientists which allows details to be picked out in astonishing clarity.Experts at the University of East Anglia have developed a computer algorithm which enhances areas of red and green, frame-by-frame.The software could run through a set-top box and would work in real-time, altering whatever programme was being watched.“Programmes which contain a large amount of red and green in their images such as sports, cookery and nature, would be particularly enhanced.” said Prof Graham Finlayson from UEA’s School of Computing Sciences.“It will help to improve the viewing experience for colour blind people.”The software, called Eyeteq, would be available to users as an option in the menu.Developers say the main benefit is that it can be watched by normally sighted people, as the picture for them is barely altered.Christopher Cytera, managing director of UEA spin-out company Spectral Edge, said: “Eyeteq provides the perfect solution for the living room TV screen.“Our trials have proved the concept, and it is now ready for integration into prime time consumer technology to transform how colour blind people, and their families, watch TV.”Colours are just light waves moving at different frequencies. Colour-blind people struggle to pick up the frequencies of red and green because of a misalignment of light-receptor cells in their eyes.But the new technology modifies the properties of certain frequencies so that red and green colours on the screen can be recognised by the eye.Colour blindness affects around 2.7 million people in the UK (250 million worldwide), including 1 in 12 men.The condition means that those affected cannot see images, including TV, with as much clarity as those with normal vision.The new technology is now available for integration into consumer set top boxes.Source: telegraph

Paris named world’s best student city 2015
Update Time: 2014-12-04 16:07:51
For the third consecutive year, Paris has topped a newly released ranking of the most student-friendly cities in the world for, among other things, being home to world-class institutions, renowned academics and offering low tuition fees. Though the City of Light may be known more for its luxury boutiques and fine dining restaurant scene than for being a budget-friendly destination, in fact, analysts who compiled the QS Best Student Cities list say that Paris is a hotbed of intellectual and academic activity and likewise offers a slew of student-friendly incentives. The index was based on five main factors: university rankings, student mix, quality of living, employment and affordability. Leading the top 10 list are Canada and Australia, which landed two spots each for cities like Melbourne, Sydney, Montreal and Toronto. Overall, the US led the top 50 list with eight cities, followed by Australia (6) and the UK (4). The best student city, meanwhile, is home to 17 QS-ranked universities (a previously released ranking of the best institutions around the world), second only to London which secured 18 spots. The report also points out that students in Paris enjoy a solid reputation among employers, who will actively seek out graduates from elite universities like ENS Paris, Ecole Polytechnique ParisTech, Sciences Po Paris and the Université Paris-Sorbonne -- all of which have produced some of the most influential philosophers, scientists, writers and artists in the last century, analysts note. Likewise, low tuition fees counterbalance the high cost of living in Paris, the report says. In a bid to make it more student-friendly, the city has also been offering free admission into museums and national monuments for visitors under the age of 26 since 2009. And don’t forget, it’s also Paris, the report adds. “But finally, all the measurements used to create the QS Best Student Cities still don’t capture the real appeal of studying in Paris, one of the world’s most historic, culturally vital and beautiful cities.” Here are the Best Student Cities in 2015: 1. Paris 2. Melbourne 3. London 4. Sydney 5. Hong Kong 6. Boston 7. Tokyo 8. Montreal 9. Toronto 10. Seoul Source: Euronews

Museum switches on historic computer
Update Time: 2014-12-03 14:19:41
A project to recreate one of Britain's pioneering computers has reached a key milestone. The first recreated parts of the re-built Edsac machine have been switched on at The National Museum of Computing.The Electronic Delay Storage Automatic Calculator first ran in 1949 and was created to serve scientists at Cambridge University.Few parts and plans were left of the original which has made the job of recreating the machine a difficult one."We don't have blueprints to follow, so to create an authentic Edsac we have to adopt a 1940s mindset to re-engineer and redesign the machine," said Andrew Herbert, leader of the recreation effort.Students who worked with Edsac's creators have been helping to guide the project, said Mr Herbert."We face the same challenges as those remarkable pioneers who succeeded in building a machine that transformed computing."Mercury tubesDesigned by Sir Maurice Wilkes, Edsac was the first computer specifically designed to be a computational workhorse. As well as aiding scientists, the machine was copied by cake maker Lyons to create the Leo - which was one of the first widely-used business computers.The original machine used 3,000 valves arranged in a series of racks to crunch numbers, and fills a floor space 20 metres square.The machine is being re-built in public at TNMOC and today saw the official opening of the Edsac exhibit and the switch on of the machine's "clock" that will keep all of Edsac's parts working in harmony. Other computational units of the machine will be added and switched on as work progresses.One element that will not be duplicated in the modern replica is the system Edsac used as its memory store.The original used long tubes of mercury to hold data but modern-day health and safety rules do not permit these to be used in the museum. Instead, the recreators are using a memory system based on nickel that was used in many machines that came after Edsac.The work on the recreated Edsac is due to be finished in late 2015. Once finished, TNMOC said children visiting the museum will be able to write programs to run on the venerable machine.The project began in 2011 and initially its 20-strong team of volunteers only had photographs of the original to work from.However, in June this year plans of the original were discovered that are now being used to check and guide the work of the Edsac rebuild team.Source: BBC

Social media told to simplify terms and conditions

Social networking firms including Facebook and Twitter are being told to make it clearer to members how they collect and use their data.A report by the Commons Science and Technology Select Committee says the firms' terms and conditions are far too long and complex.The MPs say users may not be aware of how their details can be used by websites and apps.Any reasonable person would struggle with long privacy policies, they add.The committee says reading such documents has been likened to "engaging with Shakespeare".And it says that the rules have been designed for use in US courtrooms and to protect organisations in the event of legal action rather than to convey information.The Chairman of the Committee, Andrew Miller MP, pointed to an experiment where Facebook had manipulated users' emotions by varying the stories they saw in their newsfeeds.He said this "highlighted serious concerns about the extent to which ticking the 'terms and conditions' box can be said to constitute informed consent when it comes to the varied ways data is now being used by many websites and apps".T&Cs updatesThe report calls on the government to set standards which organisations can sign up to, promising to explain how they use personal data in clear, concise and simple terms.Facebook recently unveiled updated terms and conditions policiesthat it claims are simpler and easier to read. It says it has "listened to people who have asked us to better explain how we get and use information".Meanwhile Twitter has clarified its use of data in a blogpost, which explains that it collects data on the apps which users have on their phones in order to "deliver tailored content that you might be interested in".This includes promoted tweets from advertisers. Twitter goes on to explain how users can turn off this form of data collection.Relationship of trustThe Science Committee's report also says there is a problem with apps which request information which they do not obviously need, so as to provide their service.It says companies should have a greater responsibility to explain why they need to collect information.The government does not escape criticism in the report.The Committee cites the NHS Care data programme, which was delayed after concerns about patient privacy.This is described as an example of where the relationship of trust between data collector

YouTube Music Key subscription service is unveiled
Publish Time: 2014-11-13 17:48:00
Google's YouTube is starting a subscription service that allows users to stream ad-free music videos and to download them for offline use. The £9.99 monthly fee for Music Key also provides membership to Google Play All Access, its existing "all-you-can-eat" song stream and download facility.It is set to pose a challenge to Spotify, Rdio, Beats Music and other audio-only "unlimited" music services.The launch had been delayed by a dispute with independent labels.However, Google said it had now signed deals with hundreds of indies worldwide.That has enabled it to include tracks from artists including Billy Bragg, who had previously said YouTube was trying to "strongarm" labels into agreeing to "low rates" by threatening to block their material altogether if they did not take part.He told the BBC his music had been included as part of an agreement signed by Merlin - which represents indie labels - but that he had not been informed about the details.The BBC understands that the terms of the deal state that the more plays a video has, the bigger the share of the subscription pool its publisher receives.Brad Nevin, chief executive of The Orchard group of indie labels, said he thought the deal struck was both fair and "a phenomenal opportunity".Digital habitsAndroid devices will be first to be able to save clips, followed by Apple's phones and tablets, but the facility will not extend to PCs yet.The mobile devices will also be able to continue playing music in the background when they switch to other programs.In addition to album tracks, Music Key offers downloads of concert recordings, remixes, "unreleased" rarities and cover versions recorded by others.YouTube describes itself as "the biggest music service on the planet", but Google Play is thought to lag far behind Spotify's 12.5 million paying subscribers.One expert said the new offer might tempt a number to jump ship."If you are someone who only listens to Spotify and doesn't listen to YouTube, this won't be a good enough reason to switch," said James McQuivey, principal analyst at the Forrester Research consultancy."There is a certain comfort in the well-established digital habits that people already have."But if you - as many people do - listen to both Spotify and use YouTube for music, then this is genuinely a reason to switch, because you not only have all the unlimited music but also the ability to move from audio to video, which is a very compelling experience."Those unwilling to pay can still access a new Music home page on YouTube's apps and web service, which:Makes it easier to find and play albums from beginning to end.

European scientists launched a probe from spaceship Rosetta on Wednesday in an historic attempt to examine the surface of a comet, starting a seven-hour descent that is seen as the most difficult phase of a ten-year mission. The European Space Agency earlier gave the final go-ahead for separation of the lander, named Philae, from Rosetta, which has been orbiting comet 67P/Churyumov-Gerasimenko since August. "Now it's up to gravity to bring it down," Stefan Ulamec, Philae Lander Manager from German Aerospace Center DLR said, as reported by Reuters. The probe is expected to touch down at around 1030 ET and confirmation of the landing is expected some 30 minutes later.

Background light suggests many stars 'outside galaxies'
Publish Time: 2014-11-07 18:05:00
A new study of the universe's background light has suggested that as many as half its stars might be hidden in the space between galaxies. Measurements were made by two cameras sent beyond the atmosphere on a rocket.After subtracting all the interference from dust and galaxies, the leftover light has ripples in it, which the study's authors ascribe to lone stars, flung out during galactic collisions.Other scientists believe it comes from whole galaxies that are very distant.The new results are published in the journal Science.Prof Jamie Bock from Nasa's Jet Propulsion Laboratory, one of the report's authors, described the extragalactic background light (EBL) as "kind of a cosmic glow"."It's very faint - but basically the spaces between the stars and galaxies aren't dark. And this is the total light made by stars and galaxies during cosmic history," Prof Bock told the BBC.Earlier measurements from rockets and satellites had shown that there was more fluctuation in this background than the sum total of known galaxies could explain.At least two proposals were made to account for the extra light: it might come from very early, distant galaxies that formed when the universe was much younger, or it might come from stray stars outside galactic boundaries.Prof Bock's team set out to study the EBL in detail, in terms of its colour and its distribution, to try and settle the debate.Checking it twiceTwo rocket flights were used to collect the data, in 2010 and 2012, as part of an experiment dubbed CIBER: the cosmic infrared background experiment.On each 10-minute flight, a 10m (30ft) sounding rocket travelled briefly beyond the Earth's atmosphere and two infra-red cameras took wide-angle images of the sky.Doing the measurements twice allowed the researchers to rule out fluctuations coming from the dust within our own solar system."[On the second flight] we're looking through a completely different patch of the solar system, and we see the same signal," Prof Bock explained."It's been really nice to have multiple flights, so we can do all these checks."Once all the non-background light, such as galaxies themselves, was discarded - "you kind of surgically remove them" from the images, Prof Bock said - the team was left with a clean picture of the EBL.The brightness and the blueness of the light in that picture, they claim, support the idea that it comes from stars stripped of their galaxies."It's inconsistent with [the light coming from] the very first galaxies, because it would look a lot redder," Prof Bock said.The report also says there is so much light in the recordings that there might be just as many stars outside galaxies as inside them."Astronomers know this stripping happens, but we're saying it's much more prevalent."'Perfectly possible'Other researchers are less certain of the data's implications.Jo Dunkley, a professor of astrophysics at the University of Oxford, said she did not think the evidence for vast numbers of lonely stars was compelling - "though it would obviously be really interesting if it were"."This is a big question in astronomers' minds, because we can't assign all the

French health watchdog warns on 3D usage for children
Publish Time: 2014-11-07 14:58:00
A French health watchdog has recommended that children under the age of six should not be allowed access to 3D content. The Agency for Food, Environmental and Occupational Health and Safety (Anses) added that access for those up to the age of 13 should be "moderate".It follows research into the possible impact of 3D imaging on still-developing eyes.Few countries currently have guidelines about 3D usage.According to Anses, the process of assimilating a three-dimensional effect requires the eyes to look at images in two different places at the same time before the brain translates it as one image."In children, and particularly before the age of six, the health effects of this vergence-accommodation conflict could be much more severe given the active development of the visual system at this time," it said in a statement.Nintendo warningIt is not the first time questions have been raised about the safety of 3D, which is used in many feature films as well as on some video games, TVs and computer screens.Italy has sought to restrict the use of 3D glasses by young children, following a similar warning from its national health agency last year.When Nintendo released its 3D video console in 2010 it warned that playing games on it could damage the eyesight of children under six.More and more firms are creating 3D-enabled products and Apple is rumoured to be developing a 3D display that can be viewed without the need to wear special glasses.The American Optometric Association has said that it has had no reports of eye damage as a a result of viewing 3D content.Source: BBC

Facebook sets up 'dark web' link to access network via Tor
Publish Time: 2014-11-03 18:39:00
Facebook has created the ability for users to connect directly to the social network via anonymising "dark web" service Tor. While it was already possible to access Facebook via Tor, the new set-up means all data is encrypted and Tor users are not mistaken for hacked accounts.Users could access the site "without losing the cryptographic protections" of Tor, Facebook said.It may appeal to people in places where the network is blocked.China, Iran, North Korea and Cuba are among countries that have attempted to prevent access to the site.Facebook is the first Silicon Valley giant to provide official support for Tor, a network built to allow people to visit web pages without being tracked and to publish sites whose contents would not show up in search engines.Facebook's move would prove popular among those who wanted to stop their location and browsing habits from being tracked, said Dr Steven Murdoch, from University College London, who was consulted by Facebook for the project.He explained users would still need to log-in, using real-name credentials, to access the site.He told the BBC: "It's quite hard to use a social network completely anonymously, it somewhat defeats the point, unless you're just reading information."But just because you want to tell Facebook your name, doesn't mean they should be able to find out your location and your browsing habits."The crucial change is the new Tor service - accessed through a Tor browser at https://facebookcorewwwi.onion/ - means all communication remains in the anonymous Tor network. Previously, some traffic would leave the closed network and access the open internet, potentially exposing a user's location and other information.Dr Murdoch dismissed suggestions the move could anger governments who regularly approached Facebook with requests to hand over user information."It's not so much protecting people from governments," said Dr Murdoch, "but protecting from people who are spying on communications - that could be anyone from criminals to marketers."Facebook, along with other major web companies, is currently pushing for permission to be more transparent over government requests it receives.Security blockageIt has been possible to access Facebook through Tor for some time, albeit with some frustrations.Tor is a network that anonymises users. One of the key ways it does this is by routing internet traffic through several locations - making it hard to track down where the user is browsing from.But when accessing Facebook, this causes problems. One of the site's security measures is that if a user tries to log-in from an unexpected location, it will flag this as evidence the account has possibly been compromised.Of course, it could just mean that a user has changed location - holidaymakers often find they must go through additional security steps, such as naming people in pictures, before being able to log-in while abroad."[Tor's] design means that from the perspective of our systems a person who appears to be connecting from Australia at one moment may the next appear to be in Sweden or Canada," explained Facebook engineer Alec

One wi-fi hotspot for every 150 people, says study
Publish Time: 2014-11-03 15:12:00
The UK has one wi-fi hotspot for every 11 people and worldwide there is one for every 150, new research from wi-fi provider iPass indicates. It suggests there will be 47.7 million public hotspots worldwide by the end of 2014.France currently has the most hotspots, followed by the US and UK.Hotspots are designed to fill the gaps in coverage left by mobile networks and are often offered free of charge.The study is one of the first comprehensive looks at the distribution of global wi-fi. A clickable map of hotspots around the world shows the numbers in each region and where they are located - in homes, on trains, planes, airports and retail outlets.HomespotsOver the next four years, global hotspot numbers will grow to more than 340 million, the equivalent of one wi-fi hotspot for every 20 people on earth, the research finds.But this growth will not be evenly distributed. While in North America there will be one hotspot for every four people by 2018, in Africa it will be one for every 408.While Europe currently has the most dense wi-fi coverage, Asia will overtake it by 2018, according to the report.The research suggests that the vast majority of hotspots - nearly 34 million - are in homes. These hotspots are part of a growing trend to extend home wi-fi to the local community.Increasingly firms such as BT are turning home wi-fi routers into public wi-fi hotspots which will provide free net access to other subscribers to the network.It does so without affecting the bandwidth of the customer whose home it is in.US provider Comcast caused controversy when it introduced its public home wi-fi service in the summer because customers were not given the option to opt out before receiving it.Such "homespot" public wi-fi will see explosive growth rising to more than 325 million in 2018 and taking wi-fi "from the cities to the suburbs", according to the research."Every second home you walk past will be a public hotspot that you can use if you are part of that provider's network," said June Bower, chief marketing officer at iPass.There are nearly 7.5 million hotspots in shops, cafes and hotels and and a much smaller number - nearly 11,000, on trains, planes and in airports. But wi-fi on transport is also set to grow massively, the report indicates.Google wi-fiUnlike the mobile network, which tends to be run by three or four big players in each country, wi-fi hotspots are controlled by many different providers.According to the research, more than 50% of all commercial hotspots are controlled by brands whose core business is not telecommunications.Run by cafes, hoteliers and retailers, it can make the network "somewhat chaotic", according to Ms Bower."At the moment you have to have a separate log-in for every hotspot and ultimately the winning providers are those that will offer the easier access experience," she said.And there is opportunity there for the big technology brands."Everyone has a Google log-in. Google could become a hotspot provider as could Facebook or Apple."In fact Google is already dabbling in the wi-fi market.In 2013, it made a deal with Starbucks to offer free wi-fi to 7,000 coffee
