PROVIDENCE, R.I. [Brown University] — For decades, carefully logging data about how mice go through the motions of their daily routines has been a tedious staple of behavioral and neuroscience research:

• Hour 2, minute 27: mouse 4 is sleeping;
• Hour 3, minute 12: mouse 7 is eating;

and so on. It's a task most people would happily cede to automation. Now, says Thomas Serre, assistant professor of cognitive, linguistic and psychological sciences at Brown University, that's finally possible.

Having a sibling, especially a twin, impacts your life. Your twin may be your best friend or your biggest rival, but throughout life you influence each other. However, a recent study published in Psychological Science, a journal of the Association for Psychological Science, shows that having an opposite-sex twin may impact you even before you are born: females with a male co-twin score higher on mental rotation task than females with a female co-twin.

Researchers have developed a new data transmission system that could substantially improve the transmission capacity and energy efficiency of the world's optical communication networks.

ESA's GOCE gravity mission has recovered from a glitch that prevented the satellite from sending its flow of scientific data to the ground. News of the recovery comes earlier than expected, thanks to the fervent efforts of a team of experts.

The recovery follows a serious communications malfunction on 8 July, when the Gravity field and steady-state Ocean Circulation Explorer (GOCE) satellite suddenly failed to downlink scientific data to its receiving stations.

Only 45 percent of the 354 million annual visits for acute care in the United States are made to patients' personal physicians, as Americans increasingly make busy emergency departments, specialists or outpatient care departments their first point of contact for treatment of new health problems or a flare up of a chronic condition like asthma or diabetes.

In 2009, newly installed photovoltaic (PV) cells world-wide produced a peak amount of electricity estimated at 7.4 GW, out of which 5.8 GW was located in Europe. Similarly to previous years, this shows the EU's dominance, where more than three quarters of the world's new solar systems were installed. By the end of 2009, Europe's cumulative installed PV electricity generation capacity (existing and newly installed) was 16 GW, which is about 70% of the world's total (22GW).

London, UK (September 6th, 2010) – Discussions about end of life practices in Germany have been almost taboo for over half a century, but now intense debate is underway as professional bodies review their guidelines to physicians caring for the dying. A new study out today in Palliative Medicine, published by SAGE, reveals that German physicians do hasten death in some cases, against current ethical guidelines - sometimes without sufficient patient involvement.

Gland, Switzerland - Russian oil and gas company Rosneft is conducting oil and gas exploration work that may have caused the critically endangered western gray whale to flee its main feeding ground.

Tests and offshore installment of equipment by Rosneft for a major seismic survey began in late August, despite repeated calls from 12 governments, NGOs, scientists and the public to postpone the survey because of potential risks to the whales.

A mathematical tool known as a Monte Carlo analysis could help improve the way X-rays are used for mammography and reduce the number of breast cancers missed by the technique as well as avoiding false positives, according to research published this month in the International Journal of Low Radiation.

UCSF researchers today unveiled a prototype model of the first implantable artificial kidney, in a development that one day could eliminate the need for dialysis.

The device, which would include thousands of microscopic filters as well as a bioreactor to mimic the metabolic and water-balancing roles of a real kidney, is being developed in a collaborative effort by engineers, biologists and physicians nationwide, led by Shuvo Roy, PhD, in the UCSF Department of Bioengineering and Therapeutic Sciences.

While we are often exposed to bacteria in our food which could cause food poisoning, we don't always become ill - why should this be so?

Professor Colin Hill who is presenting his work at the Society for General Microbiology's autumn meeting in Nottingham today describes how bacteria use different tricks to aid their survival inside the body, helping to explain why food poisoning can be so unpredictable.

CAMBRIDGE, Mass. -- Plants are good at doing what scientists and engineers have been struggling to do for decades: converting sunlight into stored energy, and doing so reliably day after day, year after year. Now some MIT scientists have succeeded in mimicking a key aspect of that process.

NASA satellite data has noticed that Tropical Storm Fiona is getting "longer." That is, the storm is elongating in almost a north-south direction, indicating that she's weakening and may not make it through the weekend. Meanwhile, forecasters are watching two other areas for development in the eastern Atlantic this weekend.
