TAU develops tumor destruction method that also creates immunity

Even when surgical tumor removal is combined with a heavy dose of chemotherapy or radiation, there's no guarantee that the cancer will not return. Now researchers at Tel Aviv University are strengthening the odds in favor of permanent tumor destruction - and an immunity to the cancer's return - with a new method of tumor removal.

Los Alamos team sees unprecedented proof of ion's role in enzymatic process

A Los Alamos National Laboratory research team has harnessed neutrons to view for the first time the critical role that an elusive molecule plays in certain biological reactions. The effort could aid in treatment of peptic ulcers or acid reflux disease, or allow for more efficient conversion of woody waste into transportation fuels.

Magnesium essential for absorption and metabolism of vitamin D and calcium

Magnesium deficiency is an important factor in the results obtained from vitamin D. According to Dr. Carolyn Dean, MD, ND, magnesium expert and Medical Director of the nonprofit Nutritional Magnesium Association, the effectiveness and benefits of vitamin D are greatly undermined in the absence of adequate levels of magnesium in the body.

Plant-derived bioscavenger protects against pesticide and nerve agent organophosphate poisoning

The brain is forever chattering to itself, via electrical impulses sent along its hard-wired neuronal "Ethernet." These e-messages are translated into chemical transmissions, allowing communication across the narrow cleft separating one neuron from another or between neurons and their target cells. Of the many kinds of molecules involved in this lively chemical symposium, acetylcholine is among the most critical, performing a host of functions in the central and peripheral nervous system.
