New class of antibiotics discovered by chemists Posted: 07 Mar 2014 01:59 PM PST A new class of antibiotics to fight bacteria such as methicillin-resistant Staphylococcus aureus and other drug-resistant bacteria that threaten public health has been discovered by a team of chemists. The new class, called oxadiazoles, was discovered in silico (by computer) screening and has shown promise in the treatment of MRSA in mouse models of infection. MRSA has become a global public-health problem since the 1960s because of its resistance to antibiotics. In the United States alone, 278,000 people are hospitalized and 19,000 die each year from infections caused by MRSA. Only three drugs currently are effective treatments, and resistance to each of those drugs already exists.

NASA's WISE survey finds thousands of new stars, but no 'Planet X' Posted: 07 Mar 2014 01:06 PM PST After searching hundreds of millions of objects across our sky, NASA's Wide-Field Infrared Survey Explorer (WISE) has turned up no evidence of the hypothesized celestial body in our solar system commonly dubbed "Planet X."

Promising news for producing fuels through artificial photosynthesis Posted: 07 Mar 2014 10:36 AM PST There's promising news from the front on efforts to produce fuels through artificial photosynthesis. A new study shows that nearly 90 percent of the electrons generated by a hybrid material designed to store solar energy in hydrogen are being stored in the target hydrogen molecules.

Self-acceptance could be the key to a happier life, yet it's the happy habit many people practice the least Posted: 07 Mar 2014 08:10 AM PST Happiness is more than just a feeling; it is something we can all practice on a daily basis. But people are better at some 'happy habits' than others. In fact, the one habit that corresponds most closely with us being satisfied with our lives overall -- self-acceptance -- is often the one we practice least.

Squeezing light into metals: Engineers control conductivity with inkjet printer Posted: 07 Mar 2014 05:37 AM PST Using an inexpensive inkjet printer, electrical engineers produced microscopic structures that use light in metals to carry information. This new technique, which controls electrical conductivity within such microstructures, could be used to rapidly fabricate superfast components in electronic devices, make wireless technology faster or print magnetic materials.

Europe may experience higher warming than global average Posted: 06 Mar 2014 04:15 PM PST The majority of Europe will experience higher warming than the global average if surface temperatures rise to 2 degrees C above pre-industrial levels, according to a new study.

Earth's mantle plasticity explained: Missing mechanism for deforming olivine-rich rocks Posted: 06 Mar 2014 08:22 AM PST The Earth's mantle is a solid layer that undergoes slow, continuous convective motion. But how do these rocks deform, thus making such motion possible, given that minerals such as olivine (the main constituent of the upper mantle) do not exhibit enough defects in their crystal lattice to explain the deformations observed in nature? Scientists have provided an unexpected answer to this question. It involves little known and hitherto neglected crystal defects, known as 'disclinations', which are located at the boundaries between the mineral grains that make up rocks.

How apes and humans evolved side by side Posted: 04 Mar 2014 09:54 AM PST In a new book, a paleoanthropologist incorporates his research with a synthesis of a vast amount of research from other scientists who study primate evolution and behavior. The book explains how apes and humans evolved in relation to one another, and why humans became a bipedal, tool-making, culture-inventing species.

Range of electrical frequencies that help heal chronic wounds tested by researchers Posted: 04 Mar 2014 08:35 AM PST Hard-to-heal wounds, like diabetic ulcers, fester because of insufficient blood supply at the wound site. However, the application of an electrical stimulus can promote the growth of blood vessels, and new research examines the best stimulus parameters -- such as frequency and magnitude -- for successful therapy.

Solar power: Making it less expensive and more efficient Posted: 04 Mar 2014 06:50 AM PST Researchers are reporting early results on a way to make solar-powered panels in lights, calculators and roofs lighter, less expensive, more flexible (therefore less breakable) and more efficient.

How ancient Greek plays allow us to reconstruct Europe's climate Posted: 03 Mar 2014 05:39 AM PST The open air plays of the ancient Greeks may offer us a valuable insight into the Mediterranean climate of the time, reports new research. Using historical observations from artwork and plays, scientists identified 'halcyon days', of theater friendly weather in mid-winter.

Meditation makes you more creative Posted: 19 Apr 2012 07:23 AM PDT Certain meditation techniques can promote creative thinking. This is the outcome of a study by cognitive psychologists.
