A low-testosterone man newly married to a high-testosterone woman might seem destined to be henpecked but a Penn State study found that such a coupling actually produced a marriage where the wife provided better social support for her mate.
Dr. Catherine Cohan, assistant professor of human development and family studies, says, “It’s not necessarily the case that higher testosterone is all bad. Testosterone is related to assertiveness which can be good or bad depending on whether it is m
Scientists from the Universities of Sheffield and Leeds will soon be able to study some of the most elusive particles known to man, thanks to a giant telescope under the sea that looks down towards the centre of the Earth rather than up into the sky.
Together with fellow scientists from across Europe they are building a telescope 2400m (one and a half miles) under the Mediterranean Sea to detect neutrinos. These tiny elementary particles hardly exist at all, having no charge and almost no m
OxLoc Ltd today announced the launch of the Asset Alert for monitoring condition and location of goods in transit and advising the customer of any problems by a text or e-mail alert. The autonomous tag is self powered with its own battery and can be located easily on an asset or container without expensive installation.
Asset Alert is aimed at Intermodel transportation, containers and wagons and uses a number of external sensors to detect conditions such as temperature, relative humidity an
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.
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
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
Imagine a mask that could allow a person to breathe the oxygen in the air without the risk of inhaling a toxic gas, bacterium or even a virus. Effectively filtering different kinds of molecules has always been difficult, but a new process by researchers at the University of Rochester may have paved the way to creating a new kind of membrane with pores so fine they can separate a mixture of gases. Industries could use these types of membranes for extracting hydrogen from other gases for fuel cells tha
Scientists at Rockefeller University and Weill Medical College of Cornell University have discovered how estrogen initiates physical changes in rodent brain cells that lead to increased learning and memory — a finding, the researchers contend, that illustrates the likely value of the hormone to enhance brain functioning in women.
Their study, published in the March 15 issue of The Journal of Neuroscience, describes for the first time a chain of molecular events that is activated in the brain
Fox Chase Cancer Center researchers and their colleagues have developed a mouse model of the most prevalent and deadly form of human ovarian cancer — epithelial ovarian cancer. The mouse model provides a better opportunity to study the cause of ovarian cancer, examine the genes involved and test preventive, diagnostic and treatment approaches that could be applied to human ovarian cancer.
“These transgenic mice offer us a valuable scientific tool that never before has been available to ova
Study involving over 24,000 people finds general life satisfaction affects attitude toward marital happiness
In a large longitudinal study that sheds new light on the association between marital status and happiness, researchers have found that people get a boost in life satisfaction from marriage. But the increase in happiness is very small — approximately one tenth of one point on an 11-point scale — and is likely due to initial reactions to marriage and then a return to prior le
Dartmouth research group has found a new and unexpected way our attention can be grabbed – by grabbable objects. Their study, which appears in the March 17 advance online issue of Nature Neuroscience, demonstrates that objects we typically associate with grasping, such as screwdrivers, forks or pens, automatically attract our visual attention, especially if these items are on a person’s right-hand side.
In the brain, there are two primary visual pathways, one for identifying objects (p
A biological process using three different types of fungi to control common plant diseases and mite pests has been developed by researchers at the Hebrew University’s Faculty of Agricultural, Food and Environmental Quality Sciences in Rehovot.
Use of these fungi enables crops to overcome such plant diseases and pests without having to apply environmentally-polluting chemicals, said Abraham Sztejnberg, the Hebrew University’s Francis Ariowitsch Professor of Agriculture, a member of the resear

In the latest edition of Nature (March 13th, 2003) a group of scientist led by professor Pertti Hari from the University of Helsinki presents a novel observation: ultraviolet radiation induced a flux of nitrogen oxides (NOx) from pine needles to the atmosphere. This result is interesting because nitrogen oxides participate in several essential chemical reactions in the atmosphere. On the other hand, plants can utilize the nitrogen of NOx as their nutrient.
It has been difficult to detect the
Discovery highlights molecular screening work at Institute of Chemistry and Cell Biology
Boston, Mass. — Scientists studying how cells know when and where to divide now have a new tool to study the final fast stage of cell division. The first experiments using this new tool reveal some of the molecular conversation that helps a cell tightly choreograph the time and place of pinching into two cells. In the March 14 Science, researchers from Harvard Medical School (HMS) and colleagues report
Researchers participating in the California NanoSystems Institute (CNSI) at the University of California at Santa Barbara (UCSB) and at Los Angeles (UCLA) have invented a new technique for producing “Ultra High Density Nanowire Lattices and Circuits”–the title of their paper being published expeditiously at 2:00 p.m. March 13 on the “Science Express” website, Science Magazine’s rapid portal for publication of significant research findings to appear subsequently in print in Science.
