...oo long. Their fight to save the injured brain can spill over into nearby areas, damaging neighboring structures. Brain cells and immune system cells in the blood stream alter their function and essentially gather at the damage site, Strauss says. They can proliferate and release chemicals that cause th...

Sleep enforces the temporal sequence in memory

Previous findings from a research group headed by Jan Born at the University of Lbeck have confirmed the widely held view that long-term memories are formed particularly during sleep, and that t...

NJIT professor obtains patent to uncover trace elements of airborne pollutants

...nts in air or the problems that occur when tankers spill gasoline, remain of concern to scientists. "Typical concentrations of many pollutants can be small--only a few molecules of pollutants in every part per billion of air or water molecules," Mitra said.

New test predicts blood cancer's sensitivity to experimental cancer drug

...ll's power plants, or mitochondria, to rupture and spill out chemicals that cause the cell to die and be tagged for disposal. This class of drugs is expected to be relatively non-toxic to most normal cells, which are much less dependent on Bcl-2 function than are cancer cells to stay alive. "It's essenti...

Genetic variation may reduce Alzheimer's risk

Free hemoglobin is toxic; it can easily lose its iron group, causing cell-damaging oxidative stress. Now it appears freed hemoglobin may also bind to beta amyloid, which may ...

Exercise, aspirin consumption and childbirth may alter cancer risk

Figuring out function from bacteria's bewildering forms

...acteria commonly used in drug production and toxic spill clean-ups. Bacteria are often used as workhorses in the mass-conversion of one molecule to another. Improving the speed of uptake of a substrate molecule by the bacteria could hypothetically speed drug production. "If we could figure out how to get t...

Natural born killers

...iller cells are armed with enzyme-filled sacs that spill their deadly contents when infected or cancerous cells cross the killer's path. In addition, they secrete cytokines, chemical messengers that jumpstart the T and B cell response. What the Salk and Pasteur teams discovered is that when all three Tyro...

Unlike a major oil spill that causes problems for a time and can be cleaned up, chronic oil pollution is continuous and hard to track or clean up because it comes bit by bit, sometimes in ballast water from passing ships, sometimes in seepage from offshore oil rigs.
