As little as 15 minutes of exercise a day can reduce overall mortality rates in patients with prostate cancer, according to a new study.
A new study reveals that craving a cigarette while performing a cognitive task not only increases the chances of a person's mind wandering, but also makes that person less likely to notice when his or her mind has wandered.
Scientists have developed a way to rapidly manipulate and sort different cells in the blood using magnetizable liquids. The findings could dramatically improve the speed and sensitivity of tests used to detect cancer biomarkers, blood disorders, viruses and other diseases.
A new scientific study warns that sea level could rise much faster than previously expected. By the year 2100, global sea level could rise between 0.75 to 1.9 meters, according to a new paper.
Certain genes switch their nuclear position in tumor cells, offering a potential new method of diagnosing cancer, say researchers.
Asthmatic smokers may be able to reverse some of the damage to their lungs that exacerbates asthmatic symptoms just by putting down their cigarettes, according to new research.
While supplements can help some people meet their nutrition needs, eating a wide variety of nutrient-rich foods is the best way for most people to obtain the nutrients they need to be healthy and reduce their risk of chronic disease, according to a newly updated position paper titled "Nutrient Supplementation" from the American Dietetic...
Lawrence Berkeley National Laboratory scientists Lynn Price and Nan Zhou expected the long banquet and endless toasting. What they did not expect on a recent trip to a cement plant in central China was a three-hour variety show by the factory employees, complete with folk dancing, song-and-dance numbers and comedians. Even more surprising were the lyrics to one of the songs: "I started to listen...
After heart attack patients' arteries were cleared by reperfusion, progenitor cells, derived from the patients' own bone marrow, were infused into that artery. This reduced the risk of death or another heart attack. The finding also holds promise that bone marrow progenitor cells can reduce debilitating or fatal heart failure in heart attack survivors. Larger trials are needed to confirm the...
Blood vessel blockage, a common condition in old age or diabetes, leads to low blood flow and results in low oxygen, which can kill cells and tissues. Such blockages can require amputation resulting in loss of limbs. Now, using mice as their model, researchers have developed therapies that increase blood flow, improve movement and decrease tissue death and the need for...
The 2009 H1N1 virus, which ignited a worldwide "swine flu" panic earlier this year, used a novel strategy to cross from birds into people, scientists have found. The finding could help those surveilling the world for new flu variants and those developing antiviral drugs.
Researchers report that the human body has an entirely unique and separate sensory system aside from the nerves that give most of us the ability to touch and feel. Surprisingly, this sensory network is located throughout our blood vessels and sweat glands, and is for most people, largely imperceptible. This discovery may shed light on the causes of unexplained chronic pain conditions such as...
Astronomers have taken the deepest image yet of the Universe in near-infrared light. The faintest and reddest objects in the image are likely the oldest galaxies ever identified, having formed between only 600-900 million years after the Big Bang.
Although a trip to summer camp is highly anticipated by over 11 million children and adults each year, sending a child off to summer camp can be a source of anxiety for parents. However, findings from a new study should ease their concerns.
An international group of anthropologists offers a new theory about the diffusion of maize to the Southwestern United States and the impact it had. The study suggests that maize was passed from group to group of Southwestern hunter-gatherers.
Most primary care physicians active in the Medicare program work in practices with too few patients to reliably measure significant differences in common measures of quality and cost performance, according to a new study.
Using a nanoparticle from corn, a scientist has found a way to lengthen the shelf life of many food products and sustain their health benefits.
NASA's effort to deploy the first satellite mission to advance global precipitation observations from space moved closer to this goal when agency officials approved critical elements for the Global Precipitation Measurement mission on December 2.
Using a branch of science that crosses disciplines to study complex problems, a researcher is introducing a new way to understand and treat lower back pain, a condition affecting more than 40 million Americans and costing billions of dollars each year.
New, precise imaging of the heart's motions showed important differences between men and women and different age groups. The gender differences in heart motion were not all explained by anatomical differences. The new imaging technique could lead to earlier diagnosis of cardiovascular...
A multi-institutional study has identified a potential personalized treatment target for the most common form of ovarian cancer. The research team discovered that a gene called MAGP2 -- not previously associated with any type of cancer -- was overexpressed in papillary serous ovarian tumors of patients who died more quickly. They also found evidence suggesting possible mechanisms by which MAGP2...
Researchers have found that young adults engaging in casual sexual encounters do not appear to be at increased risk for harmful psychological outcomes as compared to sexually active young adults in more committed relationships. While this study focused on the psychological impact, researchers caution that the physical risks of casual sex should not be...
The second phase of a clinical trial testing a new stem-cell-based therapy on injured heart muscle has been launched by researchers at the University of Texas Medical School at Houston.
The testing of DNA from a statewide blood screening program for newborns in Wisconsin was able to identify infants with T-cell lymphopenia, a blood disorder that affects the child's immune system, a disease in which early identification is important, according to a new study.
