SPENCER, Mass. - Several residents were taken to hospitals Wednesday with burns and rashes after the town's water supply was accidentally treated with too much corrosive lye, police said.
The US Food and Drug Administration (FDA) is considering redefining 'chocolate' to allow substitution with less expensive and lower quality ingredients.
There may be a silver lining to the dark cloud of migraines: improved memory.
U.S. researchers have found that women with a history of migraines had less cognitive decline as they aged than women who didn't have the debilitating headaches.
"This was a complete surprise," noted study author Amanda Kalaydjian, a research fellow at the National Institute of Mental Health. "We found that people with migraines, specifically people with migraines with aura -- which is even more counterintuitive -- didn't even decline over time at all."
Kalaydjian's team published its finding in the April 24 issue ofNeurology. Her research was conducted while a doctoral student at Johns Hopkins School of Public Health.
Other experts were similarly surprised by the finding.
CHICAGO - As much as doctors would like to deny it, subtle attention from friendly drug sales representatives can have a big impact on what drugs they prescribe, according to two U.S. studies published on Monday.

So far only a few, faint warnings have been raised, mainly by people who are so sensitised to the electromagnetic radiation emitted by mobiles, their masts and Wi-Fi that they become ill in its presence. The World Health Organisation
estimates that up to three out of every hundred people are " electrosensitive" to some extent. But scientists and doctors - and some European governments - are adding their voices to the alarm as it becomes clear that the almost universal use of mobile phones may be storing up medical catastrophe for the future.

Parents of autistic children have reported feelings of anxiety and guilt over whether they should give their children the MMR vaccine, a new study has found.
They have told researchers they felt they had "let their children down" by deciding to give their children the triple vaccine to ward against measles, mumps and rubella, despite assurances from scientists and doctors that it is safe.

A major immunisation campaign is to take place in Iraq in a bid to prevent an outbreak of measles.
The World Health Organization and Unicef are overseeing the work of 8,000 volunteers who aim to give up to 3.9 million children the MMR vaccine.
The children, aged one to five, have missed out on their routine jabs because of the instability in Iraq.
Serotonin is a major signaling chemical in the brain, and it has long been thought to be involved in aggressive behavior in a wide variety of animals as well as in humans. Another brain chemical signal, neuropeptide Y (known as neuropeptide F in invertebrates), is also known to affect an array of behaviors in many species, including territoriality in mice. A new study by Drs. Herman Dierick and Ralph Greenspan of The Neurosciences Institute in San Diego shows that these two chemicals also regulate aggression in the fruit fly, Drosophila melanogaster.
In a series of studies that used drug treatments and genetic engineering we have produced flies that make increased or decreased amounts of serotonin, or whose nerve cells that use serotonin or neuropeptide F are silent or inactive. Our investigations showed that the more serotonin a fly makes, the more aggressive it will be towards other flies. Conversely, presence of neuropeptide F has an opposite modulatory effect on the flies' behavior, reducing aggression. Serotonin and neuropeptide F are part of separate circuits in the brain, circuits which also differ to some extent between males and females. Male flies are much more aggressive.
Both of these chemical modulators affect aggression in mammals, and finding these effects in flies suggests that the molecular and neural roots for this complex social behavior are of ancient evolutionary origin.
Scientists in the Greene Infectious Disease Laboratory of the Columbia University Mailman School of Public Health and colleagues in the Victorian Infectious Diseases Reference Laboratory in Melbourne, Australia and 454 Life Sciences have discovered a new virus that was responsible for the deaths of three transplant recipients who received organs from a single donor in Victoria, Australia.
The previously unknown virus, which is related to lymphocytic choreomeningitis virus (LCMV), was found using rapid sequencing technology established by 454 Life Sciences and bioinformatics algorithms developed in the Greene Laboratory with support from the National Institute of Allergy and Infectious Diseases. Known strains of LCMV have been implicated in a small number of cases of disease transmission by organ transplantation, however, the newly discovered virus is sufficiently different that it could not be detected using existing screening methods.
