Deep in Africa’s Kalahari Desert lies the “Devil’s claw,” a plant that may hold the key to effective treatments for arthritis, tendinitis and other illnesses that affect millions each year. Unfortunately, years of drought have pushed the Devil’s claw toward extinction, so scientists are scrambling to devise new ways to produce the valuable medicinal chemicals [...]
Researchers are using a new and faster method of rapidly producing highly targeted monoclonal antibodies for use in diagnostic tests as well as a temporary therapy to stave off infectious diseases such as the H1N1 (swine flu) virus.

Two nanoscale devices recently reported in two separate journals harness the potential of carbon nanomaterials to enhance technologies for drug or imaging agent delivery and energy storage systems, in one case, and, in the other, bolster the sensitivity of oxygen sensors essential in confined settings, from mines to spacecrafts.
It is a little known fact that Arabic scientists made important contributions to the fields of astronomy, geography, engineering and mathematics, and chemistry that last to this day, a researcher reports.

A new study of honey bees lends support to the idea that nurture (an organism’s environment) may ultimately influence nature (it’s genetic inheritance).

Common variations in a gene — previously shown to be associated with Retts Syndrome, autism, and mental retardation — are associated with differences in brain structure in both healthy individuals and patients with neurological and psychiatric disorders.

Attention all smokeless tobacco users: It’s time to banish the comforting notion that snuff and chewing tobacco are safe because they don’t burn and produce inhalable smoke like cigarettes. A study that looked beyond the well-researched tobacco hazards, nitrosamines and nicotine, has discovered a single pinch — the amount in a portion — of smokeless [...]

Scientists have identified a new method for selectively killing metastatic melanoma cells, which may lead to new areas for drug development in melanoma — a cancer that is highly resistant to current treatment strategies.
