Age is the equalizer, according to a study that provides new insights into why women live longer than men
Men die earlier than women. This fact leads scientists and medical researchers to conclude that gender and age are two basic factors continuously affecting body functions, disease categories and even life expectancy. Previous research has determined that gender influences brain structure and functions; however, in considering the cardiac pacemaker, there is still debat
MRI used in a breakthrough study to explore how we gather information
How do we learn? At the same time, when learning is conscious, does the brain engage in learning based on experience? Many scientists have believed that the two processes are independent of each other. Now, new research findings published in the current edition of the Journal of Neurophysiology, suggest otherwise.
Background
Procedural learning, such as perceptual-motor sequence learning, is thought
T cells and antibody-producing B cells carry out immune defense against specific pathogens such as viruses. Antibodies and T cell receptors are highly diverse molecules that can recognize millions of different molecules. Upon encounter of a foreign antigen (such as a molecule from the surface of a virus), T cells and B cells whose receptors match that particular antigen expand dramatically, providing the immune system with a large number of very specific defenders. After an attack is fought off, the
Mechanical engineers at Purdue University have discovered a simple and speedy method for pinpointing and fixing design flaws in new cars.
Douglas E. Adams, an assistant professor of mechanical engineering at Purdue, said he stumbled across a mathematical solution to a design bottleneck in automotive engineering. Engineers now have to rely on complex, time-consuming mathematical models to solve design problems in new cars that are soon to begin rolling off the assembly line.

A family history of breast cancer does not increase a woman`s chances of developing womb cancer, finds a 20-year study in the Journal of Medical Genetics.
Cancers of the lining of the womb (endometrium) and breast share some of the same reproductive, hormonal, and lifestyle risk factors. The evidence for a genetic link between the two types of cancer has so far been inconclusive.
But a team from the US National Cancer Institute and the Uniformed Services University of the Health Sciences
A new technique enables doctors to directly examine the lining of milk ducts in the breast for early signs of cancer and other abnormalities, according to research at Washington University School of Medicine in St. Louis. The researchers used the technique, known as ductoscopy, to detect breast abnormalities in women with a condition called pathologic nipple discharge (PND).
The findings are published in the October issue of the journal Surgery.
“This technique is more successful
