'Dung of the devil' plant roots point to new swine flu drugs

Scientists in China have discovered that roots of a plant used a century ago during the great Spanish influenza pandemic contains substances with powerful effects in laboratory experiments in killing the H1N1 swine flu virus that now threatens the world. Their report is scheduled for the Sept. 25 issue of ACS' Journal of Natural Products, a monthly publication.

75 percent would consider letting an unsupervised trainee perform surgery if it could be done quicker

Having an operation done quickly appears to be more important to patients than having a fully qualified surgeon carry it out. A study of 80 surgical patients found that three-quarters would consider allowing a competent unsupervised trainee junior doctor to perform their entire operation if it meant they could have it done more quickly. The results have surprised doctors, as before waiting times...

999: The human face of economic crisis

As the economy continues to unravel, a series of papers published today assess the effects of the crisis on children's health, education, and rights in East Asia and the Pacific. Crisis for Children, a special issue of the journal Global Social Policy, asserts investments can be made that will not only advance children's rights and break the cycle of poverty, but also safeguard countries' future...

Baby boomers' boon? LED light and green tea cream to smooth facial wrinkles

Scientists in Germany are reporting a major improvement in their potential new treatment for facial wrinkles that could emerge as an alternative to Botox and cosmetic surgery. The noninvasive technique combines high-intensity light from light-emitting diodes (LEDs) and a lotion made of green tea extract. It works 10 times faster than a similar anti-wrinkle treatment that uses LEDs alone, the...

Cement's basic molecular structure finally decoded

In the 2,000 years since the Roman Empire employed a naturally occurring form of cement to build a vast system of concrete aqueducts, researchers have analyzed the molecular structure of natural materials and created entirely new building materials such as steel. Oddly enough, the three-dimensional crystalline structure of cement hydrate had eluded scientific attempts at decoding, until an MIT...

Doctors Fear Asking Mentally Ill To Quit Smoking

People with mental illnesses such as depression and anxiety are the heaviest smokers in the country, but their doctors are afraid to ask them to quit. They assume if their patients try to quit, their mental disorders will get worse. That is a myth, according to a tobacco addiction specialist. This population's tobacco use needs to be treated, he...

Doctors fear asking mentally ill to quit smoking

People with mental illnesses such as depression and anxiety are the heaviest smokers in the country, but their doctors are afraid to ask them to quit. They assume if their patients try to quit, their mental disorders will get worse. That is a myth, says Brian Hitsman, a tobacco addiction specialist at Northwestern University. This population's tobacco use needs to be treated, he says. Hitsman has...

ESA Campaign Reveals Glimpse Of Future Sentinel-3 Imagery

As part of the development process for ESA’s Sentinel-3 Earth observation mission, remote-sensing experts carried out an extensive experiment campaign across southern Europe this summer. The results provide valuable insight into the imagery the mission will deliver after it is launched in...

ESA campaign reveals glimpse of future Sentinel-3 imagery

As part of the development process for ESA's Sentinel-3 Earth observation mission, remote-sensing experts carried out an extensive experiment campaign across southern Europe this summer. The results provide valuable insight into the imagery the mission will deliver after it is launched in 2013.

EuroHeart 2009

Research that highlights striking differences across different countries in Europe both in terms of national prevention policies and cardiovascular mortality is being presented today by the EuroHeart mapping project at a major European Conference "Combating heart disease and stroke: Planning for a Healthier Europe."

Fermi Large Area Telescope reveals pulsing gamma-ray sources

Scientists at the Naval Research Laboratory Space Science Division and a team of international researchers have positively identified cosmic sources of gamma-ray emissions through the discovery of 16 pulsating neutron stars. Using the Large Area Telescope, the primary instrument on NASA's Fermi Gamma-ray Space Telescope satellite, the discoveries were made by conducting blind frequency searches on...

Genome of Irish potato famine pathogen decoded

An international research team has decoded the genome of the notorious organism that triggered the Irish potato famine in the mid-19th century and now threatens this season's tomato and potato crops across much of the US. The study reveals an unusually large genome size -- more than twice that of closely related species -- and an extraordinary genome structure, which together appear to enable the...
