Scientists slow down the speed of light travelling in free space

Scientists have managed to slow photons in free space for the first time. They have demonstrated that applying a mask to an optical beam to give photons a spatial structure can reduce their speed.

3-D view of the Greenland Ice Sheet opens a window into ice history

Scientists using ice-penetrating radar data collected by NASA's Operation IceBridge and earlier airborne campaigns have built the first comprehensive map of layers deep inside the Greenland Ice Sheet, opening a window on past climate...Show More Summary

Dragnet for epilepsy genes

An international team of scientists has taken a new path in the research into causes of epilepsy: The researchers determined the networks of the active genes and, like a dragnet, looked for the "main perpetrators" using a computer model. Show More Summary

Scientists Find Fish Under 2.5K Feet of Antarctic Ice

With the help of a special hot-water drill, a large, multidisciplinary team of scientists has become the first to bore through the Ross Ice Shelf—the biggest body of floating ice in the world, roughly the size of France—and sample life below nearly 2,500 feet of ice. What...

Black holes exist with unbounded speeds of propagation - in math, anyway

Lorentz invariance (LI) is a cornerstone of modern physics, and strongly supported by observations. In fact, all the experiments carried out so far are consistent with it, and no evidence to show that such a symmetry needs to be broken at a certain energy scale. Show More Summary

Lucid dreams and metacognition: Awareness of thinking, awareness of dreaming

To control one's dreams and to live out there what is impossible in real life - a truly tempting idea. Some persons - so-called lucid dreamers -can do this. Researchers from the Max Planck Institute for Human Development in Berlin and...Show More Summary

Linguistics: Tonal languages need humid climates

The weather impacts not only upon our mood but also our voice. An international research team including scientists from the Max Planck Institutes for Psycholinguistics, Evolutionary Anthropology and Mathematics in the Sciences has analyzed the influence of humidity on the evolution of languages.

Why all-nighters don't work: How sleep, memory go hand-in-hand

Scientists have long known that sleep, memory and learning are deeply connected but how has remained a mystery. The question is, does the mechanism that promotes sleep also consolidate memory, or do two distinct processes work together?...Show More Summary

Boston's leaky pipes release high levels of heat-trapping methane

A research team estimates that each year about 15 billion cubic feet of natural gas, worth some $90 million, escapes the Boston region's delivery system. The findings have implications for other regions, especially cities that, like Boston, are older and rely on natural gas for a significant and increasing portion of their energy needs.

New technique for producing cheaper solar energy suggested by research

Pioneering new research could pave the way for solar energy to be converted into household electricity more cheaply than ever before. The global PV market has experienced rapid growth in recent years due to renewable energy targets and CO2 emission controls.

Unusually elastic protein found by researchers; may have originated in cnidarian elastomer

An unusually elastic protein has been discovered in one of the most ancient groups of animals, the over 600-million-year-old cnidarians. The protein is a part of the "weapons system" that the cnidarians use: a kind of harpoon launched from their body at extremely high speed. Show More Summary

Stalking versus cyberstalking: Effects on victims, their responses compared

The devastating effects of stalking and cyberstalking – harassing or threatening communication via the Internet – are explored in a new study. Key among the findings is that victims of cyberstalking engage in more 'self-protective' behaviours -- such as changing their normal routines or getting a new email address -- than victims of stalking.

Celiac disease rate among young children has almost tripled in past 20 years

The number of young children diagnosed with celiac disease in the UK has almost tripled over the past 20 years, but kids from poorer families are only half as likely to be diagnosed with the condition, reveals research.

Checklist devised to spot elderly patients most at risk of death

A checklist has been designed to spot elderly hospital patients likely to die within the next three months, a new article outlines. The researchers emphasize that the checklist is not intended to substitute healthcare for the elderly who are terminally ill. Show More Summary

Falls in blood pressure, cholesterol have saved 20,000+ lives in England

Falls in blood pressure and total cholesterol staved off more than 20,000 deaths from coronary heart disease in England between 2000 and 2007, shows a mathematical analysis. The impact of statins was greatest among the most affluent in the population, suggesting that these drugs have helped maintain health inequalities between rich and poor, say the researchers.

Three Extreme Objects Spotted in Milky Way Dwarf Galaxy

In the latest discovery, a multinational team of astronomers working on the High Energy Stereoscopic System (H.E.S.S.) telescopes found three extremely luminous gamma-ray sources in the Large Magellanic Cloud (LMC), a satellite dwarf galaxy of the Milky Way. These are...

Alamo impact crater: New study could double its size

Carbonate rock deposits found within the mountain ranges of south-central Nevada, USA, record evidence of a catastrophic impact event known as the Alamo impact. This event occurred roughly 382 million years ago when the ancient seafloor was struck and a submarine crater was formed. Show More Summary

Mothers don't speak so clearly to their babies

People have a distinctive way of talking to babies and small children: We speak more slowly, using a sing-song voice, and tend to use cutesy words like "tummy". While we might be inclined to think that we talk this way because it isShow More Summary
