Astronomers have measured a superstorm for the first time in the atmosphere of an exoplanet, the well-studied "hot Jupiter" HD209458b. The very high-precision observations of carbon monoxide gas show that it is streaming at enormous speed from the extremely hot day side to the cooler night side of the planet. The observations also allow another exciting "first" -- measuring the orbital speed of...
About 40 million people in the US today suffer from tinnitus, an irritating and sometimes debilitating auditory disorder in which a person "hears" sounds, such as ringing, that don't actually exist. There isn't a cure for what has long been a mysterious ailment, but new research suggests there may, someday, be a way to alleviate the sensation of this...
Two new approaches could form the basis for the first-ever human vaccine for Rift Valley fever, an infectious disease that threatens both farm animals and people, say researchers. Experimental vaccines developed with these approaches produced strong immune responses in mice and may be safer than the only available RVF vaccine, which is limited to animal...
Researchers have developed a computer program capable of identifying language that can indicate a writer's psychological state, which could serve as a screening tool. The software was used to scan more than 300,000 English language blogs that were posted to mental health Web sites. The program identified what it perceived to be the 100 "most depressed" and 100 "least depressed"...
The remarkable ability of an electron to exist in two places at once has been controlled in the most common electronic material -- silicon -- for the first time. The research findings marks a significant step towards the making of an affordable "quantum computer."
Tracking fish across Alaska's vast continental shelves can present a challenge to any scientist studying Alaska's seas. Researchers have successfully tested a possible solution in the form of underwater gliders.
The first published research to emerge from the SLAC linear collider since it was reconfigured as an ultra-bright, high-energy free electron laser offers a high speed closeup of ionizing nitrogen gas.
A fascinating new study combines snakes with brain imaging in order to uncover neural mechanisms associated with "courage." The research provides new insight into what happens in the brain when an individual voluntarily performs an action opposite to that promoted by ongoing fear and may even lead to new treatment strategies for those who exhibit a failure to overcome their...
Two studies have found that hoarding friends doesn't necessarily diminish forlorn feelings and that loneliness is a matter of perception. Superficial relationships, researchers say, can not only result in feelings of detachment, but also contribute to certain health-related...
Patients who had experienced a heart attack and lowered their blood homocysteine levels with folic acid and vitamin B12 supplementation did not have an associated lower risk of heart attack, coronary death or stroke, according to a new study. However, the researchers did find that folic acid supplementation did not increase the risk of cancer, which has been...
Researchers have found why patients with a variant form of xeroderma pigmentosum (XPV), an inherited genetic disorder characterized by extreme sensitivity to the sun, are more susceptible to skin cancers than the general population. Their finding sets the stage for research into therapies that would help protect people with XPV from developing skin...
Children who experience maltreatment such as emotional, physical and sexual abuse are more likely to experience frequent headaches, including chronic migraine, as adults, say scientists.
Researchers have pinpointed a set of biological mechanisms through which estrogen confers its beneficial effects on the cardiovascular system, independent of the hormone's actions on cancer.
Going barefoot in the home, wearing slippers, or socks with no shoes may contribute falls among the elderly.
In a study with implications for the advertising industry and public health organizations, neuroscientists have shown they can use brain scanning to predict whether people will use sunscreen in the next week better than the people themselves can predict whether they will do so. This is the first persuasion study in neuroscience to predict behavior...
Although long-term care of sick or disabled loved ones is widely recognized as a threat to the caregiver's health and quality of life, a new study finds that in some contexts, helping valued loved ones may promote the well being of helpers.
A team of US scientists has returned from a two-week expedition to Guatemala's tropical high-mountain Lake Atitlan, where they are working to find solutions to the algae blooms that have assailed the ecosystem and the drinking water source for local residents.
Scientists have identified a trio of bacterial enzymes that can catalyze key steps in the conversion of plant sugars into hydrocarbon compounds for the production of green transportation fuels.
The firestorm that followed the November 2009 release of guidelines that would have reduced use of screening mammograms in women aged 40 to 49 highlights challenges for implementing the findings of comparative effectiveness research (CER), according to a new analysis. Meeting such challenges -- which may become more common due to increased funding for CER -- requires better communication to the...
Despite current policy trends, many clinicians continue to hold positive attitudes toward gifts from and marketing interactions with pharmaceutical and device companies, according to a new study.
Entomologist Mark Hoddle is in Peru to look for known avocado pests, in particular, the avocado seed moth, Stenoma catenifer, that could wreak havoc on California's avocados should the pest make its way to the state. This pest could also attack and survive on California bay laurel, a plant native to California that is closely related to the avocado. Peruvian avocados are already being imported...
A new study looking at the patterns of early childhood cancers across Great Britain has found no association between a mother living near to a mobile phone base station during her pregnancy and the risk of that child developing cancer before reaching the age of five.
Alcohol abuse is highly disruptive of circadian rhythms, which refers to the timing of daily rhythms. A new animal study has used hamsters to test for the influence of wheel-running on alcohol intake. Results indicate that exercise, perhaps through stimulation of brain reward pathways, may be able to reduce alcohol intake in...
Until recently, the disastrous scale of the threat posed by salmon farms to the fauna and National Park of the Aysén region of southern Chile was entirely unknown. The unexpected discovery was made by researchers who were studying acoustic communication among the native whales in the region. The researchers not only discovered that the salmon industry is rapidly spreading to the hitherto largely...
