Water window imaging opportunity

August 21, 2014 11:19 am | by EurekAlert! | Comments

Ever heard of the water window? It consists of radiations in the 3.3 to 4.4 nanometre range, which are not absorbed by the water in biological tissues. New theoretical findings show that it is possible to develop coherent radiations within the water window....

AAAS: Sri Lanka images show no significant increase in public facilities, despite promises

August 21, 2014 11:10 am | by EurekAlert! | Comments

Thousands of Sri Lankans remain refugees five years after a long civil war, and satellite-image analysis seems to reveal many new housing-like structures and development in a military zone in the northern part of the country.

Electric sparks may alter evolution of lunar soil

August 21, 2014 10:04 am | by EurekAlert! | Comments

The moon appears to be a tranquil place, but modeling done by University of New Hampshire and NASA scientists suggests that, over the eons, periodic storms of solar energetic particles may have significantly altered the properties of the soil in the moon's coldest craters through the process of sparking—a finding that could change our understanding of the evolution of planetary surfaces in the solar system....

New feeding tube connectors will improve patient safety

August 21, 2014 9:31 am | by EurekAlert! | Comments

New feeding tube connectors, designed by an international standards process, will be available soon and will improve patient safety. According to an invited review published in the OnlineFirst version of Nutrition in Clinical Practice (NCP), the official journal of the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.), the new connectors will greatly reduce the occurrence of misconnection that can be harmful....

Many solve civil justice problems on their own, rarely involving attorneys, says study

August 21, 2014 9:21 am | by EurekAlert! | Comments

Many of life's problems are also civil legal problems, but people don't see them that way. As a result, they often deal with them on their own, and rarely involve lawyers or courts, or even other third parties, according to a recent study. They rarely say that concern about the cost of legal help is a factor, contrary to common assumptions....

Water and sunlight the formula for sustainable fuel

August 21, 2014 9:10 am | by EurekAlert! | Comments

An Australian National University (ANU) team has successfully replicated one of the crucial steps in photosynthesis, opening the way for biological systems powered by sunlight which could manufacture hydrogen as a fuel. "Water is abundant and so is sunlight. It is an exciting prospect to use them to create hydrogen, and do it cheaply and safely," said Dr Kastoori Hingorani....
