Vitamin A's paradoxical role in influencing symmetry during embryonic development revealed

In this week's journal Nature, scientists at the Salk Institute for Biological Studies report that they have solved one of the "holy grail" puzzles of developmental biology: the existence of a mechanism that insures that the exterior of our bodies is symmetrical while inner organs are arranged asymmetrically.

Common antibiotic called minocycline may slow or prevent diabetic retinopathy

The team found that minocycline, often used to treat acne, limits by about 50 percent the retinal damage caused by microglia. Microglia are cells that act as the "cleanup crew" for the Central Nervous System (CNS).

Discovery reveals how stem cells can be used to help repair acute spinal cord damage

A treatment derived from human embryonic stem cells improves mobility in rats with spinal cord injuries, providing the first physical evidence that the therapeutic use of these cells can help restore motor skills lost from acute spinal cord tissue damage.

Antibiotic minocycline might help alleviate HIV's negative effects on the brain and central nervous system

By studying animals, Johns Hopkins researchers have discovered that the antibiotic minocycline might help alleviate HIV's negative effects on the brain and central nervous system, problems that can develop even though antiretroviral therapy controls the virus elsewhere in the body.

Clues about the causes of dementia in Huntington's disease

Scientists at Melbourne's Howard Florey Institute have uncovered a clue about the causes of dementia in Huntington's disease, one of the disease's symptoms, by showing that mice susceptible to Huntington's disease have problems with learning and memory before the diseases' typical movement problems appear.

Promising new West Nile therapy cures disease in mice

West Nile virus alarmed Americans when it made its first U.S. appearance in New York City in 1999. It has since spread from coast to coast, sickened more than 16,000 Americans and killed more than 600.

Antibody for West Nile virus shows promise

Researchers have developed an antibody that can cure mice of West Nile virus (WNV) infection, a disease for which no specific treatment exists, the National Institute of Allergy and Infectious Diseases (NIAID) has announced.

Testing new manic depression drugs in slime mould

Research by University College London (UCL) scientists could lead to the development of more effective drugs for treating manic depression thanks to a new screening approach developed in a "slime mould" - a microbe that lives in leaves and dung on forest floors.

Cigarette smoking may contribute to the progression of multiple sclerosis

Researchers from the Harvard School of Public Health (HSPH) recently discovered that cigarette smoking may contribute to the progression of multiple sclerosis (MS), suggesting that quitting smoking could limit or delay central nervous system deterioration.

Brain-injury rehabilitation depends on acetylcholine circuitry

The ability of the brain to recover from such injury as stroke or trauma depends on a particular circuitry of neurons that "talk" to one another using the brain chemical acetylcholine, researchers led by James Conner and Mark Tuszynski in the Neural repair Group at UCSD have discovered.
