A twisted world: Chemists build a molecular banister Posted: 12 Nov 2014 07:27 AM PST Chemists have succeeded in twisting a molecule by combining molecular strands of differing lengths. The longer strand winds around a central axis like a staircase banister, creating a helical structure that exhibits special physical properties.

Electronic 'tongue' to ensure food quality Posted: 12 Nov 2014 07:26 AM PST An electronic 'tongue' could one day sample food and drinks as a quality check before they hit store shelves. Or it could someday monitor water for pollutants or test blood for signs of disease. With an eye toward these applications, scientists are reporting the development of a new, inexpensive and highly sensitive version of such a device.

Artificial retina could someday help restore vision Posted: 12 Nov 2014 07:25 AM PST The loss of eyesight, often caused by retinal degeneration, is a life-altering health issue for many people, especially as they age. But a new development toward a prosthetic retina could help counter conditions that result from problems with this crucial part of the eye.

Predicting dengue fever outbreaks in China using internet searches Posted: 12 Nov 2014 06:31 AM PST The habit of searching online for a diagnosis before visiting the doctor can be a powerful predictor of infectious diseases outbreaks, researchers have found. Now studies show that combining information from monitoring internet search metrics such as Baidu (China's equivalent of Google), with a web-based infectious disease alert system from reported cases and environmental factors hold the key to improving early warning systems and reducing the deadly effects of dengue fever in China.

New materials for more powerful solar cells Posted: 12 Nov 2014 06:31 AM PST Applying a thin film of metallic oxide significantly boosts the performance of solar panel cells. Researchers have developed a new class of materials comprising elements such as bismuth, iron, chromium, and oxygen. These 'multiferroic' materials absorb solar radiation and possess unique electrical and magnetic properties.

Virtual reality speeds up rehabilitation: Integrating force feedback into therapies for impaired hands Posted: 12 Nov 2014 06:30 AM PST A novel training program uses haptic technology for impaired hands that cannot function normally. This program is unique as it provides force feedback, which creates a true sense of weight to the user through the control device.

'Nudges' try to help college students live healthier Posted: 12 Nov 2014 06:30 AM PST Here's one way to try to get college students to live healthier lifestyles: They log onto their computer and get lessons and emails, telling them why they should eat better, exercise and sleep right. That's what researchers at 13 universities discovered.

Ethanol and heterogeneous catalysts for biodiesel production Posted: 12 Nov 2014 05:42 AM PST Biodiesel is an alternative fuel to conventional fossil ones. The EU policies of boosting biodiesel have achieved its implementation in the transport fuels market and increasingly its sustainable nature is being taken into account. Thus, up to 86 % of the biofuels used in the EU in 2013 achieved the certificate of sustainability, in accordance with the Community norms.

Fewer surgeries with degradable implants Posted: 12 Nov 2014 05:42 AM PST Until now, in cases of bone fracture, doctors have used implants made of steel and titanium, which have to be removed after healing. To spare patients burdensome interventions, researchers are working on a bone substitute that completely degrades in the body. Towards this end, material combinations of metal and ceramic are being used.

European spacecraft set to harpoon a comet Posted: 11 Nov 2014 08:11 AM PST Early tomorrow morning (Nov. 12), the European Space Agency's Rosetta spacecraft will deploy its comet lander, "Philae." A little over seven hours later (8 a.m. PST/11 a.m. EST), the experiment-laden, harpoon-firing Philae is scheduled to touch down on the surface of comet 67P/Churyumov-Gerasimenko. It will be the first time in history that a spacecraft has attempted a soft landing on a comet. Rosetta is an international mission led by the European Space Agency (ESA), with instruments provided by its member states, and additional support and instruments provided by NASA.

Using 3-D printers to print out self-learning robots Posted: 12 Nov 2014 05:41 AM PST On the third floor of the Department of Informatics in a university in Norway a there is a robotics laboratory which looks like a playroom. This is where researchers are testing how their robots can figure out how to move past barriers and other obstacles. The robotics team are currently comparing the performance of five robots which in theory should be equally good. Three of the five robots have four legs, one has three, another has six. The fewer legs, the less energy is consumed. One of the robots is fitted with single-joint legs. The others have legs with two joints.

The great digital divide in healthcare: Older Americans may be left behind Posted: 12 Nov 2014 05:38 AM PST When it comes to the benefits of electronic health records, older Americans may be left behind, new study says. Less than a third of Americans age 65 and over use the Web for health information and barely 10 percent of those with low health literacy -- or ability to navigate the health care system -- go online for health-related matters, according to the nationally-representative study.
