Nicotine exposure during development leads to hearing problems
Scientists know that children of women who smoke during pregnancy can develop hearing-related cognitive deficits. For the first time, researchers believe they have evidence that not only implicates nicotine as the culprit, but also shows what the substance does to the brain to cause these deficits.   view more (2006-07-19)

Tiny crystals promise big benefits for solar technologies
Los Alamos National Laboratory scientists have discovered that a phenomenon called carrier multiplication, in which semiconductor nanocrystals respond to photons by producing multiple electrons, is applicable to a broader array of materials that previously thought.   view more (2006-01-05)

Prenatal nicotine exposure reduces breathing response of newborns
Exposure to nicotine the equivalent of smoking two packs of cigarets a day produced complicated, abnormal breathing development during the first 18 days of newborn rats, University of Arizona researchers report.   view more (2006-04-06)

Pesticides exposure associated with Parkinson's disease
In the first large-scale, prospective study to examine possible links between chronic, low-dose exposure to pesticides and Parkinson's disease (PD), researchers at the Harvard School of Public Health (HSPH) have shown that individuals reporting exposure to pesticides had a 70 percent higher incidence of PD than those not reporting exposure.   view more (2006-06-27)

Ultraviolet B light exposure associated with increased risk of skin cancer
A decreased ability to repair chromosomal damage caused by exposure to ultraviolet B (UV-B) radiation in test tubes may be associated with an increased risk of the common skin cancers basal cell carcinoma and squamous cell carcinoma, but not of melanoma.   view more (2005-12-21)

Prenatal cocaine's lasting cellular effects
Although the "crack baby" hysteria of the 1980s was greatly exaggerated, cocaine use during pregnancy can cause subtle but disabling cognitive impairments — attention deficits, learning disabilities and emotional problems.   view more (2007-01-15)

'Red tide toxins' leave beachgoers breathless
The ecological phenomenon, known as Florida red tide, can be harmful for people with asthma. Florida red tides, an annual event in areas along the Gulf of Mexico, are blooms of the ocean organism, Karenia brevis (K brevis), that are concentrated along shorelines and produce highly potent aerosolized toxins.   view more (2007-01-09)
