A new study shows that humans and tiny aquatic animals known as rotifers have something important in common when it comes to sex.

Doctors have long known that snoring is hazardous to health for a number of reasons. In addition to restless nights and increased daytime sleepiness, sleep-disordered breathing (SDB) has a series of associated health problems, including increased risk of cardiovascular disease (CVD). While it is not always clear what the association between SDB and a given health problem is, new research exposes that at least one factor may help to explain the increased risk of cardiovascular problems that affects even people with mild to moderate SDB.

Los Angeles, CA (June 14, 2010) Apple juice can be a useful supplement for calming the declining moods that are part of the normal progression of moderate-to-severe Alzheimer's Disease (AD), according to a study in American Journal of Alzheimer's Disease and Other Dementias (AJADD), published by SAGE.

New research published by Cell Press in the June 15th issue of the journal Developmental Cell, reveals how plants modify their root architecture based on nutrient availability in the soil.

A new study reveals how conflict resolution works on the microscopic scale – a protein called Flower marks the weaker cells for elimination in favor of their fitter neighbors. The research, published by Cell Press in the June 15th issue of the journal Developmental Cell, furthers our understanding of a developmental process of "cell competition" and may provide some insight into pathological conditions that involve imbalances in cell fitness, such as cancer.

LA JOLLA, Calif., June 15, 2010 – Without knowing exactly why, scientists have long observed that people who regularly take non-steroidal anti-inflammatory drugs (NSAIDs) like aspirin have lower incidences of certain types of cancer. Now, in a study appearing in Cancer Cell on June 15, investigators at Sanford-Burnham Medical Research Institute (Sanford-Burnham) and their colleagues have figured out how one NSAID, called Sulindac, inhibits tumor growth.

The first "test tube baby" was born in 1978. With advances in reproductive science, an estimated one percent of all American babies are now born each year through in vitro fertilization ¬¬(IVF). But IVF and other assisted fertility treatments may be solving one problem by creating another, suggests new evidence from Tel Aviv University.

The most detailed national vegetation U.S. land-cover map to date was released today by the U.S. Geological Survey (USGS). The map will enable conservation professionals to identify places in the country with sufficient habitat to support wildlife.

The map, produced by the USGS Gap Analysis Program (GAP), can be viewed online and downloaded for free.

Researchers from the Peninsula Medical School, working in collaboration with colleagues from Glasgow Royal Infirmary and the University of Brighton, have used a unique collection of pancreas specimens taken from patients who died soon after diagnosis of type 1 diabetes to show that they respond to the ongoing process of destruction by inducing their islet cells to proliferate.

The research is published on-line at Diabetologia and is funded by Juvenile Diabetes Research Foundation.

There is a new path to defeat systemic sclerosis, also called scleroderma because of the hardening of the skin of the patients (from Greek skleros, "hard", and derma, "skin"). This path involves the B-cell of the immune system, so far only considered "innocent spectators," as Catholic University rheumatologist Gianfranco Ferraccioli, among the authors of the important research, puts it.

While South Africa comes under the world's spotlight for the World Cup, it is being scrutinised by a University of Leicester researcher because of an innovative policy initiative.

Rachel Tate, a PhD research student in the Department of Politics and International Relations at the University of Leicester, is focussing on the Maputo Development Corridor, a cross-border spatial development initiative.

Why are the international climate negotiations moving so slowly? Because countries have so far been unable to define what global fairness really is, says Thomas Sterner, Professor of Environmental Economics at the University of Gothenburg. Sterner and several other prominent economists including several recipients of the Nobel Prize in Economics spoke at the World Bank conference on development economics in Stockholm recently.

Women were just as likely to have breast abnormalities picked up by a specially trained nurse practitioner as a consultant breast surgeon, according to research published in the July issue of the Journal of Advanced Nursing.

Researchers at Glamorgan Hospital, Wales, UK, compared the findings of 126 women examined by a nurse practitioner and consultant surgeon referred to a symptomatic breast disease clinic over a 13-month period.

They produced exactly the same results in 92 per cent of cases.
