Indulging in just one small chocolate truffle can induce cravings for more sugary and fatty foods -- and even awaken a desire for high-end status products, according to a new study.

Scientists in Oregon and Washington State are reporting the development and successful testing of a new method for determining the extent of illicit drug use in entire communities from water flushed down toilets that enters municipal wastewater treatment plants.
There are many ways to die, but amyotrophic lateral sclerosis, also known as Lou Gehrig's disease must be one of the worst. By the time a patient notices muscle weakness, the neurons that control the muscles have already begun dying, in an untreatable process that brings death within two to five...
Scientists have designed a pilot-scale device that will capture significantly more of the energy in ocean waves than existing systems, and have used it to power an electricity-generating turbine.
The Big Bang is widely considered to have obliterated any trace of what came before. Now, astrophysicists think that their new theoretical interpretation of an imprint from the earliest stages of the universe may also shed light on what came before.
Rather than testing for individual marker genes or proteins, researchers have evidence that groups, or networks, of interactive genes may be more reliable in determining the likelihood that a form of leukemia is fast-moving or slow-growing.
Good quality extra-virgin olive oil contains health-relevant chemicals, ‘phytochemicals’, that can trigger cancer cell death. New research sheds more light on the suspected association between olive oil-rich Mediterranean diets and reductions in breast cancer risk.
Embryonic stem cells could provide a new way of testing drugs for dangerous side effects. Since researchers are able to make unlimited human heart cells from embryonic stem cells, they may offer a viable and scientifically exciting alternative. Barack Obama is an ardent supporter of stem cell...
Scientists have discovered where they believe would be the best place to find ice on the moon.

Adding another reason for people to watch their blood pressure, a new study shows that increased blood pressure in older adults is directly related to decreased cognitive functioning, particularly among seniors with already high blood pressure. This means that stressful situations may make it more difficult for some seniors to think...
Scientists have developed the first natural, nontoxic method for biodegrading carbon nanotubes, a finding that could help diminish the environmental and health concerns that mar the otherwise bright prospects of the super-strong materials commonly used in products, from electronics to...
The Martian arctic soil that NASA's Phoenix Mars Lander dug into this year is very cold and very dry. However, when long-term climate cycles make the site warmer, the soil may get moist enough to modify the chemistry, producing effects that persist through the colder times.
After culling the literature for observed black holes, astronomers looked at 245 active galactic nuclei to characterize the shape of material swirling around them. The result: active galactic nuclei look like donuts, funneling from a dark center. This observation should constrain theories about how the material around black holes is produced and eventually allow scientists to study black holes...
Just as the emotions it represents are dynamic, the heart's development requires dynamic shifts in proteins that prompt alternative spicing, a mechanism that allows a given gene to program the cell to make several proteins, according to a new article in the journal Proceedings of the National Academy of...
Researchers have found a new drug with the potential to alleviate jet lag and sleep disorders caused by shift work.
Scientists have identified a genetic signature that is remarkably effective at predicting the prognosis of an aggressive liver cancer in children. The research, published by Cell Press in the December issue of the journal Cancer Cell, may lead to better treatments for pediatric liver...
The findings of the world's largest study so far on the ability of children and young people to taste and what they like have now been published. Findings include: girls have a better sense of taste than boys; every third child of school age prefers soft drinks which are not...
An implantable hemodynamic monitor may help to guide medical treatment in a large subgroup of patients with heart failure: those with diastolic heart failure.
Researchers have found a potential clue to the roots of epilepsy, autism, schizophrenia and other neurological disorders.
Many products have numbers attached: megapixels for cameras, wattage ratings for stereos, cotton counts for sheets. A new study shows that consumers are heavily influenced by quantitative specifications, even meaningless ones.
A team of astronomers has used a new technique to measure the precise size of a planet around a distant star. They used a camera so sensitive that it could detect the passage of a moth in front of a lit window from a distance of 1,000 miles.
Consumers face a barrage of product claims each day. What makes those claims believable? A new study says both marketers and consumers can benefit from information about the way people process product claims.
NASA's Mars Reconnaissance Orbiter has completed its primary, two-year science phase. The spacecraft has found signs of a complex Martian history of climate change that produced a diversity of past watery environments.
Researchers have identified protein biomarkers that may let doctors detect earlier two crippling malaria variations -- one that develops in the placenta of pregnant women affecting countless unborn children, the other, cerebral malaria, that develops in the brain's blood vessels -- malaria's most deadly...
While harnessing more energy from the wind could help satisfy growing demands for electricity and reduce emissions of global-warming gases, turbulence from proposed wind farms could adversely affect the growth of crops in the surrounding countryside.
