Three new UCSF studies describe the wide reach of the tobacco industry and its influence on young people, military veterans and national health care reform.
The analyses will be published in a special July edition of the American Journal of Public Health titled "Modeling to Advance Tobacco Control Policy."
Scientists using tiny particles of genetic material to interfere in the replication process of the deadly Ebola virus have successfully prevented monkeys exposed to that virus from dying of hemorrhagic fever. The proof-of-concept study, published in this week's issue of The Lancet, suggests that such protection also should be possible in humans.
Individuals who have poor oral hygiene have an increased risk of heart disease compared to those who brush their teeth twice a day, finds research published today on BMJ.com.
ANN ARBOR, Mich.---Every autumn, as predictably as falling leaves, flu season descends upon us. Every spring, just as predictably, the season comes to a close. This cyclical pattern, common in temperate regions, is well known, but the driving forces behind it have been in question.
For kidney patients trying to control their blood pressure, reducing fluid build-up in the blood is more effective than using antihypertensive medications, according to an analysis appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN). The research suggests that lowering salt intake may help reduce build-up.
Scientist Jon Chase once worked in a lab that set up small pond ecosystems for experiments on species interactions and food webs.
"We would try to duplicate pond communities with a given experimental treatment," he says.
"We put 10 of this species in each pond, and five of these species, and eight of the other species, and 15 milliliters of this nutrient and 5 grams of that and 'sproing,' every replicate would do its own thing and nothing would be like anything else.
Jeffrey Long's lab will soon host a round-the-clock, robotically choreographed hunt for carbon-hungry materials.
The Lawrence Berkeley National Laboratory chemist leads a diverse team of scientists whose goal is to quickly discover materials that can efficiently strip carbon dioxide from a power plant's exhaust, before it leaves the smokestack and contributes to climate change.
DALLAS – May 27, 2010 – For two decades, the laboratory mouse has been the workhorse of biomedical studies and the only mammal whose genes scientists could effectively and reliably manipulate to study human diseases and conditions.
In graduate school, Jon Chase worked in a lab that set up small pond ecosystems in order to run experiments on species interactions and food webs. "And because this was an experimental science, we tried to replicate each pond system," Chase says.
DURHAM, N.C. -- Political and social chaos and a lack of international protections have put several species of rosewood trees in Madagascar in danger of becoming extinct from illegal logging, according to a policy forum paper in the latest issue of Science.
"Forty-seven of Madagascar's 48 species of rosewood (Dalbergia) are found nowhere else in the world," said Duke University graduate student Meredith Barrett, the lead author on the May 27 article.
An estimated 60 million people in Bangladesh are exposed to unsafe levels of arsenic in their drinking water, dramatically raising their risk for cancer and other serious diseases, according to the World Health Organization (WHO).
Because most of the contaminated water is near the surface, many people in Bangladesh have installed deep wells to tap into groundwater that's relatively free of arsenic.
An active compound from fungi and lower animals may well be suitable as an effective weapon against dangerous bacteria. We're talking about plectasin, a small protein molecule that can even destroy highly resistant bacteria . Researchers at the Universities of Bonn, Utrecht, Aalborg and of the Danish company Novozymes AS have shed light on how the substance does this. The authors see plectasin as a promising lead compound for new antibiotics.
These results will be published in Science journal on 28th May.
