California Attorney General says emissions plan fails to adequately protect air, public health

"Exposure to mercury can cause severe health damage, particularly to pregnant women and young children," said Lockyer. "If implemented, these rules will protect the profits of polluters at the expense of the environment, people and public health."

Urgent action needed across Europe to tackle childhood disease related to environmental conditions

Authors of a study in this week's issue of THE LANCET are calling for urgent governmental action across Europe to tackle childhood disease and deaths associated with poor environmental conditions in Europe.

Size and shape of synapses among neurons in the cerebral cortex determine long term memory capability

In a study to appear in the June 10 issue of Neuron, neuroscientists at the Picower Center for Learning and Memory at MIT show for the first time that storage of long-term memories depends on the size and shape of synapses among neurons in the outer part of the brain, the cerebral cortex.

Prenatal cocaine exposure not associated with lower full scale IQ scores

A study in the May 26 issue of The Journal of the American Medical Association (JAMA) suggests that prenatal cocaine exposure was not associated with lower full scale IQ scores, or verbal or performance IQ scores at age 4 years.

Discovery of the gene for Cornelia de Lange syndrome

An international team of researchers has discovered the gene for Cornelia de Lange syndrome, a disabling, multisystem genetic disease that affects an estimated one in 10,000 children. The finding is expected to lead to a genetic test, enabling rapid and definitive diagnosis of the syndrome, as well as prenatal testing for families who already have one child with the disease.

A protein involved in the release of neurotransmitters in the brain is essential to learning and memory

A study published today in Neuron offers the first evidence that lack of this protein - known as RIM1 alpha - causes profound deficits in the learning process. The discovery is a major step in understanding the molecular events that underlie learning and memory - complex processes that can be impaired in human neuropsychiatric disorders such as Alzheimer's disease, mental retardation and schizophrenia.

Lack of iodine prompts new Australian study

A fear that Australians could be suffering serious ill effects from lack of iodine in their diets has prompted a new study of New South Wales, Riverina residents by Charles Sturt University’s (CSU) School of Biomedical Sciences.

Scientists find parallels between human speech and bird song which gives clues to human speech disorders.

The research by a team led by Stephanie White, UCLA assistant professor of physiological science, supports the theory that two genes shared by humans and songbirds, FoxP1 and FoxP2, may play a critical role in human speech, and speech disorders. The study is published March 31 in the Journal of Neuroscience.

Discovery of new gene sheds light on human brain development

With the identification of the gene responsible for a newly recognized type of mental retardation, researchers at Beth Israel Deaconess Medical Center (BIDMC) have also discovered what appears to be the key target in the evolution of the frontal lobes of the brain's cerebral cortex. The findings offer a key insight into the complex puzzle of human brain development - and the evolution of human behavior.
