Research from the University of Maryland School of Medicine has revealed key features in proteins needed for life to function on Mars and other extreme environments.

The researchers, funded by NASA, studied organisms that survive in the extreme environment of Antarctica.

They found subtle but significant differences between the core proteins in ordinary organisms and Haloarchaea, organisms that can tolerate severe conditions such as… read more

Google wants to replace all your passwords with a ring

March 13, 2013

YubiKey-NEO-+-finger

As part of research into doing away with typed passwords, Google has built rings that not only adorn a finger but also can be used to log in to a computer or online account, MIT Technology Review reports.

At the RSA security conference in San Francisco last month, Mayank Upadhyay, a principal engineer at Google,  said that using personal hardware to log in would remove the dangers of… read more

Researchers peek at the structure of the viral Internet

March 13, 2013

viral search

At Microsoft Research’s annual technology demo day this week, researchers showed off a tool called Viral Search that attempts to measure virality in its more literal sense. That means not overall traffic over time, but the mechanics by which it passes from person to person over many generations, MIT Technology Review reports.

The software looked at 1.4 billion Tweets over the course of a year… read more

NASA rover finds conditions once suited for ancient life on Mars

March 13, 2013

An analysis of a rock sample collected by NASA’s Curiosity rover shows ancient Mars could have supported living microbes.

Scientists identified sulfur, nitrogen, hydrogen, oxygen, phosphorus and carbon — some of the key chemical ingredients for life — in the powder Curiosity drilled out of a sedimentary rock near an ancient stream bed in Gale Crater on the Red Planet last month.

“A fundamental… read more

Designing interlocking building blocks to create complex tissues

Columbia University researchers have developed a new “plug-and-play” method to assemble complex cell microenvironments in a scalable, highly precise way to fabricate tissues with any spatial organization or interest — such as those found in the heart or skeleton or vasculature.

The lock-and-key technique can be used to build cellular assemblies using a variety of shapes that lock into templates like LEGO building blocks, according… read more

A high-resolution endoscope as thin as a human hair

March 13, 2013

Engineers at Stanford University have developed a prototype single-fiber endoscope that is as thin as a human hair, with a resolution four times better than previous devices of similar design.

The “micro-endoscope” is a significant step forward in high-resolution, minimally invasive bioimaging, with potential applications in research and clinical practice. Micro-endoscopy could enable new methods in diverse fields ranging from study of the brain to early cancer… read more

Sleep discovery could lead to therapies that improve memory

But a medical study found increased risk of death from taking sleeping pills
March 13, 2013

sleeping

A team of sleep researchers led by UC Riverside psychologist Sara C. Mednick has confirmed the mechanism that enables the brain to consolidate memory and found that a commonly prescribed sleep aid enhances the process.

Those discoveries could lead to new sleep therapies that will improve memory for aging adults and those with dementia, Alzheimer’s, and schizophrenia.

Earlier research found a correlation between sleep spindles —… read more

Stanford psychologists uncover brain-imaging inaccuracies

March 12, 2013

The researchers found that traditional methods of processing fMRI data may lead scientists to overlook smaller brain structures, thus skewing their results (credit:

Traditional methods of fMRI analysis systematically skew which regions of the brain appear to be activating, potentially invalidating hundreds of papers that use the technique, according to Stanford School of Medicine researchers.

Pictures of brain regions “activating” are by now a familiar accompaniment to any neurological news story (including some in KurzweilAI — see Editor’s note below). With functional magnetic resonance imaging, or fMRI, you can see… read more

iPad explores quantum computing

March 12, 2013

A new section in Lockheed Martin’s LM Tomorrow, a free app for iPad users, explores quantum physics in an interactive, easy-to-understand format. The LM Tomorrow app received the gold-level “W3 Award” in 2012 for creative excellence on the web.

The Quantum Theory section draws on expanding research into the  potential of quantum computing to solve challenges ranging from designing lifesaving new drugs to instantaneously… read more

China’s next-generation Internet is a world-beater

An open-access report published in the Philosophical Transactions of the Royal Society last week details China’s advances in creating a next-generation Internet that is on a national level and on a larger scale than anything in the West, New Scientist reports.

At the root of the problem are “two major gaps in the architecture of the Internet”, according to a report from the… read more

MIT researchers are developing a new system called DBSeer that should help solve problems with cloud-computing services, such as inefficient use of virtual machines,  pricing of cloud services, and  diagnosis of application slowdowns.

For many companies, moving their web-application servers to the cloud is an attractive option, since cloud-computing services can offer economies of scale, extensive technical support and easy accommodation of demand fluctuations.… read more

Computer scientists at the University of California, San Diego and Google have developed a novel approach that allows the massive infrastructure powering cloud computing as much as 15 to 20 percent more efficiently.

This novel model has already been applied at Google.

Computer scientists looked at a range of Google web services, including Gmail and search. They used a unique approach to develop their… read more

Bioteeth generated from your own cells

Researchers are developing a method to replace missing teeth with new bioengineered teeth generated from a person’s own gum cells.

Current implant-based methods of whole tooth replacement fail to reproduce a natural root structure and as a consequence of the friction from eating and other jaw movement, loss of jaw bone can occur around the implant.

Research towards producing bioengineered teeth (bioteeth) has largely focused on generating… read more
