Scrutiny by NASA's newest Mars orbiter is helping scientists learn the stories of some of the weirdest landscapes on Mars, as well as more familiar-looking parts of the Red Planet. One type of landscape near Mars'south pole is called "cryptic terrain"because it once defied explanation, but new observations bolster and refine recent interpretations of how springtime outbursts of carbon-dioxide gas there sculpt intricate patterns and paint seasonal splotches.
High blood pressure appears to be associated with an increased risk for mild cognitive impairment, a condition that involves difficulties with thinking and learning, according to a report in the December issue of Archives of Neurology, one of the JAMA/Archives journals.
A new advanced noninvasive, radiosurgery toolfor treating a variety of brain disorders -- including tumors has become available. Called the Leksell Gamma Knife Perfexion, the machine is the latest generation in gamma knife radiosurgery, a noninvasive technology that delivers a finely focused, high dose of radiation to a specific area of the brain.
Oregon Health &Science University Cancer Institute researcher Jeff Tyner, Ph.D., has created a way to identify proteins that are candidates for targeted therapy in acute myeloid leukemia using an assay that yields results in just four days.
A large amount of the greenhouse gas nitrous oxide is produced by bacteria in the oxygen poor depths of the ocean. Nitrous oxide is a powerful greenhouse gas some 300 times more so than carbon dioxide, it also attacks the ozone layer and causes acid rain.
Immigrants in the United States may be less likely to report a family history of cancer, which may lead to inadequate screening and cancer prevention strategies according to a new study.
Although they look normal, people suffering from body dysmorphic disorder perceive themselves as ugly and disfigured. New imaging research reveals that the brains of people with BDD look normal, but function abnormally when processing visual details.
An Oregon Health &Science University Cancer Institute researcher has discovered that a particular hormone is responsible for driving a cancer enzyme to cause an often deadly red blood cell cancer. Researchers working with the cancer mutation in the JAK2 enzyme have found that the enzyme is dependent on the hormone TNF-alpha to grow and cause a red blood cell cancer called polycythemia vera, said principal investigator Thomas Bumm, M.D., Ph.D., OHSU Cancer Institute member.
Feeding cattle a byproduct of ethanol production causes E. coli 0157 to spike. This particular type of E. coli is present in healthy cattle but poses a health risk to humans, who can acquire it through undercooked meat, raw dairy products and produce contaminated with cattle manure.
According to a new study mouthguards worn by athletes harbor large numbers of bacteria, yeasts and molds that can possibly lead to life and/or health-threatening infectious/inflammatory diseases.
A new study comparing the composite output of 22 leading global climate models with actual climate data finds that the models do an unsatisfactory job of mimicking climate change in key portions of the atmosphere. This research raises new concerns about the reliability of models used to forecast global warming.
People who have good physical function after the age of 40 may lower their risk of stroke by as much as 50 percent compared to people who are not able to climb stairs, kneel, bend, or lift as well, according to research published in the Dec. 11, 2007, issue of Neurology, the medical journal of the American Academy of Neurology.
Geographic range maps that allow conservationists to estimate the distribution of birds may vastly underestimate the actual population size of threatened species and those with specific habitats, according to a study published online this week in the journal Conservation Biology.
Studies in mice show identifying medications or physical shielding to protect astronauts from cosmic and solar radiation will be important for the success of human space missions beyond low Earth orbit, according to researchers from the University of Florida, Cold Spring Harbor Laboratory and NASA.
