NEW YORK (Reuters Health) - Nasal sprays are routinely used to treat conditions that affect the respiratory system such as allergies and nasal congestion, but new research suggests that it may be possible to deliver medication directly to the brain by way of the nose.

For the first time in humans, a nasal spray was used to deliver hormones directly to the brain without entering the bloodstream, reports an international team of scientists led by Dr. Jan Born at the University of Lubeck in Germany.

NEW YORK (Reuters Health) - Caffeine can help premature infants to breathe and raise their heart rates, but high doses can also reduce blood flow to vital organs such as the brain, German researchers report.

The finding may help doctors walk a fine line in helping such tiny infants to survive without causing other problems, said study author Dr. Otwin Linderkamp of the University of Heidelberg. Preterm infants may need high doses of caffeine to combat some of the side effects associated with prematurity.

NEW YORK (Reuters Health) - Women who take a multivitamin supplement before conception may reduce their risk of delivering a baby with a particular, rare birth defect, preliminary study findings indicate.

In the study, regular multivitamin use beginning 3 months before and continuing during pregnancy was associated with a 60% reduction in the risk of omphalocele, a defect in the abdominal wall that strikes 1 in 4,000 to 6,000 pregnancies.

"It is clear that one of the reasons the US maintains the Iraqi sanctions is to allow the major oil companies to reap huge profits. Yet the overriding motivation behind US policies is to retain hegemony over the oil-rich Persian Gulf which provides about a quarter of the world's oil. Above all, the goal is to send an unmistakable message: that any country bold enough to stand up to the US will reap the same unprecedented and brutal consequences inflicted upon Iraq."

For this was the little white lie that first activated the American psyche, generated mass loathing, and enabled media manipulation of the global population.

Electricity Explained Getting Down To Basics

By Bruce W. Maki

Current Flow and Ohm's Law

In the early days scientists discovered a link between electro-motive force and electron flow, in a given circuit or pathway. As the EMF was increased, the amount of electron flow increased proportionally.

Some circuits had more or less electron flow when attached to a given source of EMF. Scientists arrived at three basic concepts.
