6:00 PM | Artificial Intelligence and life beyond the algorithm: Alan Turing and the future of computing
Turing is not just a historical figure; his work is still crammed with relevance - and tricky questions. It's hard to choose where Alan Turing had the biggest impact on history. The British mathematician is known as the father of computing thanks to his work on what he called a universal machine - which provided the framework for development of digital computing - and he also helped significantly shorten the Second World War through his work with the codebreakers of Bletchley Park.

4:35 PM | Protons fuel graphene prospects
Graphene, impermeable to all gases and liquids, can easily allow protons to pass through it, Univ. of Manchester researchers have found. Published in Nature, the discovery could revolutionize fuel cells and other hydrogen-based technologies as they require a barrier that only allow protons to pass through. In addition, graphene membranes could be used to sieve hydrogen gas out of the atmosphere, where it is present in minute quantities, creating the possibility of electric generators […]

4:23 PM | Converting human waste into rocket fuel
Buck Rogers surely couldn't have seen this one coming, but at NASA's request, University of Florida researchers have figured out how to turn human waste -- yes, that kind -- into rocket fuel. Adolescent jokes aside, the process finally makes useful something that until now has been collected to burn up on re-entry. What's more, like so many other things developed for the space program, the process could well turn up on Earth, said Pratap Pullammanappallil, a UF associate professor of […]

12:31 AM | The search for dark energy just got easier
Since the early 20th century, scientists and physicists have been burdened with explaining how and why the Universe appears to be expanding at an accelerating rate. For decades, the most widely accepted explanation is that the cosmos is permeated by a mysterious force known as “dark energy”. In addition to being responsible for cosmic acceleration, this energy is also thought to comprise 68.3% of the universe’s non-visible mass. Subject:  […]

12:13 AM | Efficiency breakthrough for thin-film solar devices
The large-scale deployment of solar energy has been severely hindered by the slow pace of advances in energy conversion efficiency of solar cells. This is defined as the ratio of energy output from the solar cell to input energy from the sun. To address this challenge, researchers at Swinburne University of Technology’s Centre for Micro-Photonics (CMP) have successfully synthesised one-dimensional graphenised carbon nanofibre to demonstrate an efficiency breakthrough in […]

4:25 PM | Study supports free 'super Wi-Fi'
Wireless data transmission largely takes place via WLAN networks, such as WiFi. However, these networks are currently limited to high frequency ranges at 2 GHz and above and, hence, have a limited range. The authors of the study, Arnd Weber of the Institute for Technology Assessment and Systems Analysis (ITAS) of KIT and Jens Elsner, a former member of the staff of the KIT Communications Engineering Lab, propose to extend the frequencies for free communication to include lower ranges […]

6:34 AM | Groundbreaking malware has been spying on computers since 2008
One of the most sophisticated pieces of malware ever seen has been discovered by researchers. Dubbed Regin, the tool has reportedly been spying on telecoms companies, governments, businesses, and individuals for at least the past six years, and appears to have been used by the UK’s intelligence services. Security company Symantec announced the existence of Regin yesterday, and the researchers say it is a "​groundbreaking and almost peerless" piece of malware “whose […]

6:26 AM | Microsoft shows off robot security guards
Visitors to Microsoft's Silicon Valley campus had a close encounter with security guards earlier this month. But they weren't human security guards. In fact, if you passed one in the parking lot, you might have mistaken it for some sort of mini spaceship, or perhaps something from the Doctor Who universe. But these 300-pound, 5-foot-tall structures are meant to help you stay safe, and keep the baddies away. Subject:  Robotics

5:32 AM | Boy moms more social in chimpanzees
Nearly four decades of observations of Tanzanian chimpanzees has revealed that the mothers of sons are about 25 percent more social than the mothers of daughters. Boy moms were found to spend about two hours more per day with other chimpanzees than the girl moms did. Chimpanzees have a male-dominated society in which rank is a constant struggle and females with infants might face physical violence and even infanticide. It would be safer in general to just avoid groups where aggressive […]

4:25 PM | High heels may enhance a man's instinct to be helpful
If it's help a woman needs, maybe she should wear high heels. That's the message from Nicolas Guéguen of the Université de Bretagne-Sud in France, after he observed how helpful men are towards women in high heels versus those wearing flat, sensible shoes. The study, published in Springer's journal Archives of Sexual Behavior, is the first ever to investigate how the height of a woman's shoe heel influences how men behave towards her.
