A group of researchers are reporting on a new setup, which could finally result in every facial expression made by a gamer be cloned to the avatars face. The results produced by this method are truly amazing. Commercialization of this could be a big change in multiplayer game’s immersiveness.

Immersiveness has played a significant role in games development over the recent times. Game producers have engaged every possible technique to make the gamers feel deeply involved with the game. Customization of the gaming character (avatar) is one such method, where in the gamer feels more involved when the avatar has been customized to look like him/her or to his/her liking.

Multiplayer games have taken gaming to the next level, as the gamers get to compete with real people in real time. Most multiplayer games include chat, emoticons and VOIP for letting the gamers exchange their emotions/feelings over the game. Consider one gamer wearing extra strong body armor is being shot by an enemy with a very tiny gun. Chat, emoticons or VOIP could not really carry over the expressions or emotions of these players, would it not be awesome to see the player (avatar) being shot – laughing hard in this situation. This should be possible very soon, as a group of researchers have designed a setup which makes this possible.

Was the spider’s web you found very intricate and shiny? Do you know that this could indicate several things about the spider and it’s apprehension of the environment around it?


Animals are known to use conspicuous visual signals too allure prey or deter predators. Using colors, glossiness, ornaments are some of the well known visual signals. Sometimes the colors are used to advertise to the predators about unpalatability or harmfulness. These signals may have a cost, for example metabolic expenditure and generating the color pigment. Visual signals used to attract prey could also land up attracting predators and thus involves a trade off based on the situation.

Research and media have been significantly focused on Green Tea, highlighting its health benefits. Black Tea (the regular tea consumed at homes) has now been researched and proved that it can directly influence the lifespan. Specifically, experiments on fruit flies have shown that, more than 4% extension of lifespan is possible.

Gerontology researchers have been increasingly addressing the relationship between diet and aging. It is shown that moderate calorie restriction or altering the composition of nutrients in the diet affects the lifespan and aging of organisms.

Dietary antioxidants have become popular supplements in prevention of aging. Briefly, oxygen we intake generates ‘reactive oxygen species’ (ROS), which is one of the causes for aging. Dietary antioxidants work towards scavenging the ROS in cells and build a defense base to limit the formation of new free radicals and slow down the ageing process.

Birds spend an average of 9.2% of a day in maintenance behavior and water bathing is an important element of it followed by preening and oiling. Researchers have attempted to decipher if this bathing affects their flight performance and have made some interesting observations.

As a part of their various experiments a group of researchers from UK noticed that, newly caught and handled birds tend to immediately bath in fresh water following the release into a cage. This observation prompted to believe that the bathing followed by preening was done to repair the feathers disrupted by the catching and handling. However proving that would be impossible, as analyzing the feather after the bathing and preening would again disrupt the repaired feathers. So, they tested to see the direct influence of bathing on the flight performance.

As people get older, their arms and legs become thinner, making them weak with more chances for falls and fractures.  Research is now showing why this is happening and how to handle it.

Researchers from Nottingham have been researching about this and had already shown that the food intake by the elderly cannot convert to muscles as fast as in their younger counter parts. Newer research by the same team, has now found that the suppression of muscle breakdown, which also happens during feeding, is blunted with age. They belive that a ‘double whammy’ affects people aged over 65. However the team think that weight training may “rejuvenate” muscle blood flow and help retain muscle for older people.

When they eat they don’t build enough muscle with the protein in food; also, the insulin fails to shut down the muscle breakdown that rises between meals and overnight. Normally, in young people, insulin acts to slow muscle breakdown. Common to these problems may be a failure to deliver nutrients and hormones to muscle because of a poorer blood supply.

With the recent constant increase in internet related energy consumption, researchers are trying to address one main contributing factor – Running PCs 24/7 to run BitTorrents. A new architecture is being proposed to reduce the energy consumption and also reduce the download time. While promising, the architecture comes with a major limitation.

It is estimated that 74 TeraWatts hours (TWh) per year of electricity is consumed by internet. This 74 TWh is comprised of the energy consumed at data centers as well as the individual PCs. In 2007 data centers accounted for about 2 TWh per year, while office and home computers accounted for 16 TWh per year. Further, 21% of PCs used at work are never switched off, contributing to wastage of about 1.5 TWh per year. Of the variety of reasons for the computers not being turned off, P2P applications such as BitTorrent play a vital role. Recent studies report that 40 to 73% of the internet traffic is P2P and BitTorent is the most popular p2p protocol. Users are always in the quest for “which bittorrent program is the best”.  Based on these statistics, the group of researchers focus on a proxy based architecture for BitTorrent.

Privacy has been a major issue with all Social Networks. While the networks do try to address the issues, most of the times – the solution provided is opting out of certain features. Researchers have tested a new privacy model, based on Bayesian Belief Networks – which creates a win-win situation for both the users and the network.

Everyday so many users join Social Networking Sites (SNSs) such as Facebook, Twitter, Orkut, MySpace etc, to keep up with friends, organize events with friends, make new friends, or flirt. One of the main features of SNSs is the”profile” where users post information about themselves. The profile can include real name, e-mail, physical address, phone number, academic classification, major, hometown, birthdates, sexual orientation, relationship status, interests, job history, favorite music/movies/books, etc. This revelation of personal information provides credibility to the profile and also helps match with other profiles. Users post personal information for a variety of reasons – 89% use it to keep up with friends, 57% use it make plans with friends, and 49% use it to make new friends. How much and what kind of information is revealed depend on users’ privacy concern and the trust on the SNS and its members.

BBC’s Darwin season featured ‘Charles Darwin and the Tree of Life’ – an animation which illustrates an idea that Darwin and his contemporaries used to explain the evolutionary links between living things. This amazing animation was narrated by Sir David Attenborough.


Given below is the HD video and the transcript of the narration.

Substantiating the quote “The difference between pornography and erotica is lighting”, researchers have concluded to discard an accusation on pornography of a major & undesirable affect.

Kama Sutra – the Indian text dating back to 2nd or 3rd century is one of the most well known oldest “erotic arts”. Pornography – as called today, on becoming popular was banned by various laws until Supreme Court began limiting the censorship only to hard-core pornography (in 1950s and 1960s). Pornography had its first and major win following the release of the film Deep Throat and the controversy after it, resulting in First Amendment protections for porn. Since then pornography has been sky rocketing to become a multi billion dollar industry.

The digital divide is deep and gaping between security professionals and users. Researchers have studied the differing points of views in an attempt to bridge the great divide. But do prejudices on both sides make the chasm too wide and jagged to seal?

A digital divide exists between information security managers and users. IT/IS managers mainly regard users as an information security threat, while users regard themselves as an untapped resource for security work. Research suggests these greatly differing points of view tend to make management approaches to security that do not line up well with the dynamics of the users’ working day.

Different work situations and rationalities may explain the digital divide in organizations. The security professional operates at a distance from the everyday work tasks and vulnerabilities in the company, but put toe to the line in a digital attack when vulnerabilities require crisis management. Users, however, step up to the plate every day as required to keep the company going forward as productive and profitable. For users, it is often a case of feeling like all their rights and privileges are unjustly controlled.
