Scientists knew that both these genes were expressed at increased levels as humans and mice age, but their role in the aging process was not clear.

In an act of ultimate self-sacrifice, millions of human cells commit suicide every day, making your life better by their death.

Cancer researchers have long believed that a protein called CD133 identifies a population of cancer stem cells , the only subset of cells that are responsible for tumor initiation.

Using a novel investigatory technique, researchers at the Joslin Diabetes Center have established that osteoblasts, cells responsible for bone formation, are also directly involved in the proliferation and ...

Scientists have created a tool for mopping up the clumps of mutant protein that drive neurodegeneration in Huntington's disease.

“When embryos were cloned from normal stem cells, they made normal beating hearts. However, when embryos were cloned from the GATA4/GATA6 deficient stem cells, the embryos developed but were completely lacking all heart cells”

Washington, May 17: Two proteins, called GATA4 and GATA6, in mammalian embryos play a key role in the development of a healthy heart, according to researchers at the Medical College of Wisconsin, Milwaukee. via Daily India

“I think we're going to see much more of this kind of alteration and regulation of protein properties via added sugars in many other important areas of biology.”

Changing the sugars attached to a hormone produced in the pituitary gland increased fertility levels in mice nearly 50 percent, a research group at Washington University School of Medicine in St. via Newswise

“Nitrates in food have long been erroneously linked to an increased risk of cancer”

Nitrites and nitrates, much maligned additives in processed and cured meats, may help protect the stomach from damage, suggests research from Sweden. via Food Production Daily

“We can see smaller tumors and see them in greater details”

Researchers say they've found a new tool they believe will help not only target tumors, but hopefully one day treat cancer. via WSIL

“Some people only recognize it at night, when it's quiet. You have it in one ear, and you put that ear on the pillow, and you can hear it.”

For millions of Americans, including thousands of Iraq War veterans, ringing in the ears is a condition that is annoying at best and disabling at worst. via HON

“This shows, for the first time, that the molecular response to physiological stress is organized by specific neurons and suggests similarities to the neurohormonal response to stress”

Adrenaline flows, and the stressed individual's heart pumps faster, the muscles work harder, the brain sharpens and non-essential systems shut down. via Science Daily
