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
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 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 womens 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 months 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
Although Mars is currently a cold, dry planet, geological evidence suggests that liquid water existed there around 3 to 4 billion years ago. Where there is water, there is usually…
