NASA selects studies for the asteroid redirect mission

Posted: 20 Jun 2014 11:37 AM PDT

NASA has selected 18 proposals for studies under the Asteroid Redirect Mission Broad Agency Announcement (BAA). These six-month studies will mature system concepts and key technologies and assess the feasibility of potential commercial partnerships to support the agency's Asteroid Redirect Mission, a key part of the agency's stepping stone path to send humans to Mars.

Super-stretchable yarn is made of graphene

Posted: 20 Jun 2014 11:37 AM PDT

Researchers have developed a simple, scalable method of making graphene oxide fibers that are strong, stretchable and can be easily scrolled into yarns with strengths approaching that of Kevlar.

Experimentally testing nonlocality in many-body systems

Posted: 20 Jun 2014 09:04 AM PDT

Researchers constructed multipartite Bell inequalities built from the easiest-to-measure quantities, the two-body correlators, which are capable of revealing nonlocality in many-body systems. As these are considered a fundamental resource for quantum information theory, this study will pave a new path towards experimental detection of nonlocality in large composite quantum systems.

No such thing as a 'finished article': The truth behind online news

Posted: 20 Jun 2014 07:31 AM PDT

News delivery and consumption has rapidly changed in the digital era.  No longer print-bound, the BBC, Guardian, Daily Mail and FT use blog format online news delivery, giving live commentary and many edited versions.  Powerful news sources such as Twitter also abound, challenging the more conventional channels to beat to a faster pace.

Don't tell the other team! Is this the ultimate guide to scoring and saving penalties?

Posted: 20 Jun 2014 07:31 AM PDT

As the world once again draws its attention to the FIFA World Cup, fans watch in fervor to see their country take on all-comers, in hopes that they will become the world champion. Surely, no part of the event is more tense, dramatic and exhilarating than the penalty shootout- a situation that often determines who goes through to the next round, and who heads home.

Safe water for the people in Tanzania

Posted: 20 Jun 2014 07:23 AM PDT

Hydraulic engineers and photovoltaics experts have developed a solar filtration system to produce high-quality drinking water from polluted brackish water and tested it successfully in Tanzania. The test results are currently being analyzed. The filter effectively separates undesired substances, bacteria, and viruses.

Major step forward for the world's largest optical/infrared telescope

Posted: 20 Jun 2014 07:23 AM PDT

The next major milestone towards ESO's European Extremely Large Telescope (E-ELT) has been completed. Part of the 3000-meter peak of Cerro Armazones was blasted away as a step towards leveling the summit in preparation for the construction of the largest optical/infrared telescope in the world.

Materials for the building industry: A shape-conscious alloy

Posted: 20 Jun 2014 07:21 AM PDT

When the frame of a pair of glasses is bent out of shape, it's not that easy to return it to its original form. If, however, your spectacles are made of a shape memory alloy then you don't have a problem. Just place the frame in hot water and bingo! – they're as good as new again. Empa researchers have now shown that these materials can also find applications in the building industry. For example in the reinforcement of bridges.

Sweetest calculator in the world: Sugar molecules used as part of a chemical sequence for information processing

Posted: 19 Jun 2014 06:56 AM PDT

A rectangular plastic board with 384 small wells is the setting for a chemist-researcher. The chemist carefully pipets some drops of sugar solution into a row of the tiny reaction vessels. As soon as the fluid has mixed with the contents of the vessels, fluorescence starts in some of the wells. What the chemist does here – with his own hands – could also be called in a very simplified way, the 'sweetest computer in the world'. The reason: the sugar molecules used are part of a chemical sequence for information processing.

Safety system for city, school buses will avoid accidents around bus stops

Posted: 18 Jun 2014 07:05 AM PDT

A new safety system for city and school buses that detects the presence of pedestrians in the surroundings of the bus stop, warns the driver of dangerous conditions and, ultimately, directly affects the vehicle, has been developed by researchers. The system incorporates different cameras placed at strategic points of the bus that allow the driver to see where the rear-view mirrors can't.
