FDA cannot ban import of e-cigarettes--Appeals court

A U.S. court of appeals has ruled the lower court verdict that the Food and Drug Administration (FDA) cannot regulate e-cigarettes as a drug delivery devices until it is marketed as a product to help people quit smoking.

E-cigarettes are no drug delivery devices: Judge

A federal judge has ruled that electronic cigarettes cannot be regulated as drug delivery devices by the Food and Drug Administration (FDA). This decision has left the public health community red-faced.

Bees attracted to nicotine, caffeine

Haifa, Israel -- Israeli scientists say they've discovered bees prefer nectar with small amounts of nicotine and caffeine over nectar that does not include those substances.

"This could be an evolutionary development intended, as in humans, to make the bee addicted," said University of Haifa Professor Ido Izhaki, who led the study.

Flower nectar is primarily comprised of sugars, which provide energy for the potential pollinators, the scientists said. But they said the floral nectar of some plant species also includes small quantities of caffeine and nicotine. The study sought to determine whether those substances are intended to "entice" the bees or whether they are byproducts that are not necessarily linked to any such objective.

Nicotine may prevent bioterrorism damage

Brighton, England -- British scientists say they've determined nicotine can delay the effects of ricin used during a bioterrorism attack.

Jon Mabley and his colleagues at the University of Brighton found nicotine works to block the tissue-destroying effects of ricin -- a highly toxic compound derived from castor beans. The study was conducted in laboratory models, but the scientists said nicotine agonists could potentially be used in patients exposed to ricin as a stopgap measure before other treatments take effect.

The British investigators studied the effect of nicotine on animals exposed to ricin and found it reduced death and organ failure.

Nicotine stops your cells from talking to one another

Washington, April 6 -- Nicotine may interfere with cellular communication in your body, according to a new study.

Researchers have found 55 proteins that interact with the alpha-7 nicotinic receptor, so called because nicotine binds to them when it is introduced into the body. Scientists had not previously known of those connections.

"This is called a 'nicotinic' receptor and we think of it as interacting with nicotine, but it likely has multiple functions in the brain," said study co-author Edward Hawrot, professor of molecular science, molecular pharmacology, physiology and biotechnology at Brown University.
