Scientists at the University of Pennsylvania and the Monell Chemical Senses Center in Philadelphia have found that exposure to male perspiration has marked psychological and physiological effects on women: It can brighten women’s moods, reducing tension and increasing relaxation, and also has a direct effect on the release of luteinizing hormone, which affects the length and timing of the menstrual cycle.

The results will be published in June in the journal Biology of Reproduction and

Scientists from Imperial College London, the University of Leicester, and Hammersmith Hospital have found a way to stop certain types of genetic diseases from occurring by modifying the way DNA is turned into proteins.

The research published in this month’s Proceedings of the National Academy of Science shows how the researchers have been able to restore proper expression of defective genes, and that this might potentially have a positive effect in genetic diseases such as spina

Study may open way to using bone marrow stem cells as diabetes treatment

In a finding that may open a new avenue to treating diabetes, researchers show that cells from the bone marrow give rise to insulin-producing cells in the pancreas of mice. These morphed cells actually produce the hormone insulin in response to glucose and display other characteristics demonstrating that they truly function as pancreas cells, according to a new study by researchers from NYU School of Medicine.

Researchers attack 100-year-old puzzle, learn how a single layer of particles can pack on the surface of a sphere ARLINGTON, Va. – In a discovery that is likely to impact fields as diverse as medicine and nanomanufacture, researchers have determined how nature arranges charged particles in a thin layer around a sphere. The leap forward in understanding this theoretical problem may help reveal structural chinks in the outer armor of viruses and bacteria (revealing potential drug targets

The melting of an Antarctic ice sheet roughly 14,000 years ago triggered a period of warming in Europe that marked the beginning of the end of the Earth’s last ice age, says a new study.

A paper in the March 14 issue of the journal Science suggests that a catastrophic collapse of an Antarctic ice sheet dumped roughly a million cubic litres per second of freshwater into the southern oceans, changing the climate thousands of kilometres to the north and ushering in a dramatic climate shift kn

Forests form an integral part of the Kyoto Protocol on climate change because they act as terrestrial “sinks” to soak up the carbon emissions that are contributing to global warming. Countries that have ratified the protocol can offset their carbon emissions quota by planting trees, either at home or in developing countries. But how efficient is this “carbon trading” and how good are forests at absorbing these extra carbon emissions?
