Stem cell breakthrough

Researchers at The Hospital for Sick Children (SickKids) and the University of Calgary have found that stem cells derived from adult skin can create neural cell types that can be transplanted into and function in mouse models of disease.

The science of sex and gender in human health

The National Institutes of Health (NIH) Office of Research on Women's Health (ORWH), in collaboration with the Food and Drug Administration (FDA) Office of Women's Health (OWH), have announces the launch of a new online course, "The Science of Sex and Gender in Human Health."

Taking astrocytes seriously

By blowing gentle puffs of air onto a mouse's whiskers and watching how its brain reacts, scientists are discovering that a long-overlooked signaling system in the brain is crucial to our everyday activity.

Stem cell 'fusion' occurs in tumors

An Oregon Health & Science University study is adding credence to an increasingly popular theory that fusion is what bonds stem cells with bone marrow cells to regenerate organ tissue.

Researchers pinpoint autism's genetic roots

By deleting a gene in certain parts of the brain, researchers at UT Southwestern Medical Center have created mice that show deficits in social interaction that are reminiscent of humans with autism spectrum disorders.

Possible target for future therapies aimed at delaying or stopping Alzheimer's disease

Researchers at Oregon Health & Science University's Neurological Sciences Institute (NSI) have located a possible target for future therapies aimed at delaying or stopping Alzheimer's disease.

Cholesterol takes major role in the development of fingers and toes

Although cholesterol has a bad rap as the sticky, fatty substance responsible for clogging arteries, Vanderbilt University Medical Center researchers recently found that the attachment of cholesterol to an important developmental protein controls the development of fingers and toes in mice. Without cholesterol, mice developed extra digits, as well as digits in the wrong places.

Yale researchers show how smell works within the brain

Yale scientists have systematically plotted the responses of the entire Drosophila (fruit fly) olfactory system, providing the first multi-dimensional map of the range of odorants sensed and the regions of the brain that are stimulated.

New methods for revealing nerve-muscle activity in live animals

Picking up a pencil, running a marathon, even the simple act of breathing - every time we move a muscle we depend on a series of finely-tuned interactions at the junction of nerve fiber and muscle cell.

Scientists gain greater understanding of how embryos differentiate left from right

Researchers at the Forsyth Institute have discovered a new mechanism responsible for early left/right patterning, the process by which organs locate themselves on the left or right side of the body.

Researchers develop system for observing nuclear motion

The cell is understood to be highly organized, with specialized areas for different functions and molecular motors shuttling components around.

Genetic switch that links animal growth and cancer

Laboratory discoveries by scientists at two universities may lead to new directions in cancer therapy drugs. The researchers have discovered that a genetic switch involved in growth and development of an animal is the same one used to prevent normal cells from becoming cancerous.

Reversing cell division has implications for the treatment of cancer

A scientist in the United States has apparently found a way to reverse the process of cell division.

Minimal nutritional requirements for growing and maintaining human embryonic stem cells

Researchers at Yale have established the minimal nutritional requirements for growing and maintaining human embryonic stem cells, a recipe that is critical for clinical application and for developmental studies, according to a report in the Proceedings of the National Academy of Sciences.

Scientists gauge pain in premature babies

Scientists at UCL (University College London) have measured responses to pain in the brains of premature babies and have shown that they are likely to experience ‘true’ pain rather than simply displaying reflex reactions.

Gene key to infection-fighting immune cells identified

Every time the human body encounters a virus, bacteria or other infectious agent, immune cells called B-lymphocytes multiply in lymph nodes and then swing into action to fight off the intruders.

Scientists create new molecule that holds promise in fighting disease via gene therapy

Inherited diseases, as well as many cancers and cardiovascular diseases, may eventually be helped by this approach, which delivers therapeutic genes directly to cells. These genes can correct genetic defects, for example, or help the body's immune system fight cancer cells.
