Research shows that the chemotherapy drug taxol (also called paclitaxel) could help improve recovery from spinal cord injuries. Writing in Science,* a team led by Frank Bradke, Ph.D., of the Max Planck Institute of Neurobiology in Martinsried, Germany reports that taxol helps repair spinal connections and improves walking in rats with spinal cord damage.

Scientists say they have found a way to turn body fat into a better type of fat that burns off calories and weight. The US Johns Hopkins team made the breakthrough in rats but believe the same could be done in humans, offering the hope of a new way to treat obesity.

Imagine a battlefield medic or emergency medical technician providing first aid with a special wad of cottony glass fibers that simultaneously slows bleeding, fights bacteria (and other sources of infection), stimulates the body's natural healing mechanisms, resists scarring, and—because it is quickly absorbed by surrounding tissue — may never have to be removed in follow-up care. Or, imagine diabetics with hard-to-heal wounds finding a source of relief from the battle against infections and limb amputation.

Researchers have proven that melatonin –a natural hormone produced by the body– helps in controlling weight gain –even without reducing the intake of food–, improves blood lipid profile –as it reduces triglicerids–, increases HDL cholesterol and reduces LDL cholesterol.

Stronger and tougher body armor to shield the chest, abdomen and back may be just what soldiers fighting in the Afghanistan and Iraq wars need to better protect their brains from mild injuries tied to so-called “shell shock,” results of a Johns Hopkins study in mice suggests.

A new study in rats is shedding light on how sleep-deprived lifestyles might impair functioning without people realizing it. The more rats are sleep-deprived, the more some of their neurons take catnaps — with consequent declines in task performance.

Gene therapy that uses a tiny benign virus to take a gene to the rods and cones of the eye's retina (the light-sensing organ) prevented blindness in mice with a genetic blinding syndrome, said researchers from Baylor College of Medicine in an online report of the Proceedings of the National Academy of Sciences.

In the first animal model of Amyotrophic Lateral Sclerosis (ALS), developed by Dr. Udai Pandey, Assistant Professor of Genetics at LSU Health Sciences Center New Orleans, Dr. Pandey's lab has found in fruit flies that blocking the abnormal movement of a protein made by a mutated gene called FUS also blocks the disease process.

It's a conflict with no resolution in sight. On one side, scientists who experiment on animals. On the other, animal rights activists who believe that no animal should ever be harmed. But how far can activists go before their right to free speech threatens the scientists and their work?
