Early-life exposure to traffic-related air pollution was significantly associated with higher hyperactivity scores at age 7, according to new research.
An international team of scientists reveals that a unique strain of potato blight they call HERB-1 triggered the Irish potato famine of the mid-19th century.
Bacteria resistant to the antibiotic colistin are also commonly resistant to antimicrobial substances made by the human body, according to a new study. Cross-resistance to colistin and host antimicrobials LL-37 and lysozyme, which help defend the body against bacterial attack, could mean that patients with life-threatening multi-drug resistant infections are also saddled with a crippled immune response.
NOAA presented to the U.S. Coast Guard a new report that finds that 36 sunken vessels scattered across the U.S. seafloor could pose an oil pollution threat to the nation's coastal marine resources. Of those, 17 were recommended for further assessment and potential removal of both fuel oil and oil cargo.
Pulsars have a number of unusual qualities. Like zombies, they shine even though they're technically dead, and they rotate rapidly, emitting powerful and regular beams of radiation that are seen as flashes of light, blinking on and off at intervals from seconds to milliseconds. A NASA team has built a first-of-a-kind testbed that simulates these distinctive pulsations.
Researchers have found evidence of a major cosmic event near the end of the Ice Age. The ensuing climate change forced many species to adapt or die.
A Mediterranean diet with added extra virgin olive oil or mixed nuts seems to improve the brain power of older people better than advising them to follow a low-fat diet, according to new research.
Women who smoke during pregnancy increase the risk of both obesity and gestational diabetes in their daughters
Women who smoke during pregnancy increase the risk of both obesity and gestational diabetes, in their daughters.
Parents who share a bed with their breastfed baby could face a fivefold increase in the risk of crib death, even if the parents do not smoke, according to a new study.
NASA's Mars rover Curiosity has used the drill on its robotic arm to collect a powdered sample from the interior of a rock called "Cumberland." Plans call for delivering portions of the sample in coming days to laboratory instruments inside the rover. This is only the second time that a sample has been collected from inside a rock on Mars.
Turns out, that old "practice makes perfect" adage may be overblown. New research finds that a copious amount of practice is not enough to explain why people differ in level of skill in two widely studied activities, chess and music.
Researchers have found a convenient way to make layered iron-platinum alloys and tailor their properties, a promising material for a potential new generation of data storage media.
Video games that pit players against human-looking characters may be more likely to provoke violent thoughts and words than games where monstrous creatures are the enemy, according to a new study.
Individuals who learn two languages at an early age seem to switch back and forth between separate "sound systems" for each language, according to new research. The research addresses enduring questions in bilingual studies about how bilingual speakers hear and process sound in two different languages.
Parasitic wasps switch off the immune systems of fruit flies by draining calcium from the flies' blood cells, a finding that offers new insight into how pathogens break through a host's defenses. Researchers say their findings have uncovered an important component of cellular immunity, one that parasites have learned to take advantage of.
Salamanders' immune systems are key to their remarkable ability to regrow limbs, and could also underpin their ability to regenerate spinal cords, brain tissue and even parts of their hearts, scientists have found. In new research, scientists have found that when immune cells known as macrophages were systemically removed, salamanders lost their ability to regenerate a limb and instead formed scar tissue.
While Huntington's disease (HD) is currently incurable, the HD research community anticipates that new disease-modifying therapies in development may slow or minimize disease progression. The success of HD research depends upon the identification of reliable and sensitive biomarkers to track disease and evaluate therapies, and these biomarkers may eventually be used as outcome measures in clinical trials. Biomarkers could be especially helpful to monitor changes during the time prior to diagnosis and appearance of overt symptomatology.
Nearly 20 percent of kidneys that are recovered from deceased donors in the U.S. are refused for transplant due to factors ranging from scarring in small blood vessels of the kidney’s filtering units to the organ going too long without blood or oxygen. But, what if instead of being discarded, these organs could be “recycled” to help solve the critical shortage of donor organs?
A new study of both computer-created and natural proteins suggests that the number of unique pockets – sites where small molecule pharmaceutical compounds can bind to proteins – is surprisingly small, meaning drug side effects may be impossible to avoid.
