Washington, October 2 : A team of researchers from the University of Michigan Medical School have found that the cells that make insulin in the body of people with diabetes may stop this task because of glitches in the production of a molecule called proinsulin, the precursor out of which insulin is made.

Washington: EBay, online auction giant has declared that it is replacing the creator and chief executive of its Skype online telephone arm and would take a charge of 1.43 billion dollars two years after buying the company.

Washington, Oct 2 : A new study, from researchers at the University of Virginia Health System has shed light on how cells respond to skin-damaging UV rays.

The researchers have revealed that a protein inside the body, called SOCS7, helps cells to protect themselves (or not) from DNA damage caused by ultraviolet rays.

It is known that UV rays can cause major skin problems, ranging from skin cancer to sunburns and premature wrinkles.

Washington, Oct 02 : According to a study, women over 35 years of age can avoid multiple births with the help of a new in vitro fertilization technique.

The Stanford University School of Medicine study found that more than half the women became pregnant after undergoing the procedure, called a single blastocyst transfer, which transferred one embryo into the womb.

Washington, Oct 02 : A fast, inexpensive test which can help avoid ‘out of the blue’ headaches followed by consumption of certain red wines, cheese, chocolate, and other aged or fermented foods, has been developed.

The study led by Richard A. Mathies, Ph.D., a chemist with the University of California, Berkeley reported the development of a home use test, which could prove beneficial for millions of people for curing their surprise headaches.

Washington, Oct 02 : Emory University researchers have discovered a compound in tree bark that mimics the chemical reactions of a naturally occurring molecule in the brain responsible for stimulating neuronal cell signalling.

The tree bark compound, known as gambogic amide, behaves much like Nerve Growth Factor (NGF), a molecule found in the brain.

Neuronal cell signalling plays a crucial role in the growth, plasticity and survival of brain cells.
