In 2006, Greenland experienced more days of melting snow and at higher altitudes than average over the past 18 years, according to a new NASA-funded project using satellite observations.

Daily satellite observations have shown snow melting on Greenland’s ice sheet over an increased number of days. The resulting data help scientists understand better the speed of glacier flow, how much water will pour from the ice sheet into the surrounding ocean and how much of the sun’s radiation will reflect back into the atmosphere.

Two merging black holes can generate gravitational waves so powerful that the merged hole shoots out of its host galaxy at a speed of up to 2,500 miles per second, according to a new simulation.

This research, led by Manuela Campanelli at the Rochester Institute of Technology, demonstrates for the first time that the violent recoil that follows a merger is capable of ejecting the supermassive black holes known to lie at the heart of most light-emitting galaxies. These black holes may be cruising through the universe, virtually undetectable unless they should crash into something and gain matter.

A new experiment has shown that it's possible to store multiple rudimentary memories in an artificial culture of live neurons. The ability to record information in a manmade network of neurons is a step toward a cyborg-like integration of living material into memory chips. The advance also may help neurologists to understand how our brains learn and store information.

A project which is using robots to help children with developmental or cognitive impairments to interact more effectively has just started at the University of Hertfordshire.

Professor Kerstin Dautenhahn, Dr. Ben Robins and Dr. Ester Ferrari at the University’s School of Computer Science are partners in the European Sixth Framework funded, €3.22 million Interactive Robotic Social Mediators as Companions (IROMEC) project which is investigating the use of robotic toys to enable children with disabilities to develop social skills.

A natural compound found in blueberries, tea, grapes, and cocoa enhances memory in mice, according to newly published research. This effect increased further when mice also exercised regularly.

"This finding is an important advance because it identifies a single natural chemical with memory-enhancing effects, suggesting that it may be possible to optimize brain function by combining exercise and dietary supplementation," says Mark Mattson, PhD, at the National Institute on Aging.

Polymer matrix composites with carbon black can be used as filler material and can beneficially modify the electrical and mechanical properties of the used matrixes. The polymer components of these composites are traditionally made using oleo-polymers; however, an alternative is to use natural and renewable sources as soybean oil, linseed oil, sunflower oil, etc.

Polymers derived from those natural oils can be tailored for engineering and aeronautical applications by reinforcing them with natural and synthetic fibers and clays.
