Inspired by nature, researchers create tougher metal materials

July 7, 2014 3:19 pm | by EurekAlert! | Comments

Drawing inspiration from the structure of bones and bamboo, researchers have found that by gradually changing the internal structure of metals they can make stronger, tougher materials that can be customized for a wide variety of applications – from body armor to automobile parts....

The time devoted to both conventional and social media each day is growing

July 7, 2014 3:14 pm | by EurekAlert! | Comments

Smartphones have made it far easier for people to find and exchange information and to make their views heard. In 2010, 14 per cent of the people of Sweden had access to a smartphone; three years later, in 2013, the figure is 67 per cent. More time is devoted to both online editions of traditional media and social media....

A million times better

July 7, 2014 1:19 pm | by EurekAlert! | Comments

Lasers have a fixed place in many fields of application. Yet, there are still wavelengths for which either no systems exist, or at best only large and expensive ones. On the other hand remote sensing and medical applications call for compact laser systems....

Photos of the Day: A dragon motorcycle

July 7, 2014 12:54 pm | by ECN Staff | Comments

Orange County Choppers (OCC) partnered with 3D printer manufacturer Stratasys to design a bike in the shape of a Chinese dragon. It includes a 3D-printed head, tail, and spikes made out of PC-ABS. The body, arms, and legs were machined out of a high density foam....

Forecasting the development of breakthrough technologies to enable novel space missions

July 7, 2014 11:20 am | by EurekAlert! | Comments

A new report, Technological Breakthroughs for Scientific Progress (TECHBREAK), has been published today by the European Science Foundation. The European Science Foundation (ESF) was contacted at the end of 2009 to conduct a foresight activity for the European Space Agency (ESA)....

NTU launches two new home-grown satellites

July 7, 2014 11:16 am | by EurekAlert! | Comments

The nation's latest satellites, VELOX-I and VELOX-PIII, were launched into space on India's Polar Satellite Launch Vehicle PSLV C-23 at 9.52 am (12.21 pm Singapore time), on Monday, 30 June 2014. Designed and built by students and researchers at the NTU Satellite Research Centre, the VELOX-I is a nano-satellite....

Power consumption of robot joints could be 40 perecnt less, according to a laboratory study

July 7, 2014 11:13 am | by EurekAlert! | Comments

Let us imagine, for a moment, the arm of a robot that lifts a cup of coffee to its "lips" over and over again. The joint of this robotic arm needs a certain flexibility plus an electric motor to drive the upward and downward movements. So orders have to be sent to the motor so that the joint can perform the corresponding movements....

Fruit fly immunity fails with fungus after (space)flight

July 7, 2014 11:09 am | by EurekAlert! | Comments

Before you swat away the next fruit fly, consider instead just how similar its biological complexities are to our own. In a study published in PLOS ONE, researchers led by Deborah Kimbrell, Ph.D., at the University of California, Davis (UC Davis) and their collaborators, studied how microorganisms may alter fruit flies' immunity....

Hollow-fiber membranes could cut separation costs, energy use

July 7, 2014 11:06 am | by EurekAlert! | Comments

Researchers have developed a microfluidic technique for fabricating a new class of metal-organic framework (MOF) membranes inside hollow polymer fibers that are just a few hundred microns in diameter. The new fabrication process, believed to be the first to grow MOF membranes inside hollow fibers ...

Columbia researchers observe tunable quantum behavior in bilayer graphene

July 7, 2014 11:03 am | by EurekAlert! | Comments

Columbia researchers have observed the fractional quantum Hall effect in bilayer graphene and shown that this exotic state of matter can be tuned by an electric field. The fractional quantum Hall effect, which can occur when electrons confined to thin sheets are exposed to large magnetic fields ...

With 'ribbons' of graphene, width matters

July 7, 2014 11:00 am | by EurekAlert! | Comments

Using graphene ribbons of unimaginably small widths – just several atoms across – a group of researchers at the University of Wisconsin-Milwaukee (UWM) has found a novel way to "tune" the wonder material, causing the extremely efficient conductor of electricity to act as a semiconductor....

As TV makers exit plasma, can they make up for it with LCD?

July 7, 2014 10:17 am | by DisplaySearch | Comments

The recent announcement by Samsung SDI that it will end plasma display panel (PDP) manufacturing this year also speculated that LG Electronics will shut its PDP business due to low demand, which would leave COC (Changhong) as the sole remaining plasma TV manufaturer....

From pencil marks to quantum computers

July 7, 2014 9:39 am | by EurekAlert! | Comments

One of the hottest materials in condensed matter research today is graphene. Graphene had an unlikely start: it began with researchers messing around with pencil marks on paper. Pencil "lead" is actually made of graphite, which is a soft crystal lattice made of nothing but carbon atoms....

How knots can swap positions on a DNA strand

July 7, 2014 9:34 am | by EurekAlert! | Comments

Physicists of Johannes Gutenberg University Mainz (JGU) and the Graduate School of Excellence "Materials Science in Mainz" (MAINZ) have been able with the aid of computer simulations to confirm and explain a mechanism by which two knots on a DNA strand can interchange their positions....

High-res images of inner ear could lead to new hearing loss therapies

July 7, 2014 9:20 am | by Texas A&M University | Comments

Understanding how hearing works has long been hampered by challenges associated with seeing inside the inner ear, but technology being developed by a team of researchers that includes a biomedical engineer from Texas A&M University is generating some of the most detailed images of the inner ...
