The Aim device, smaller than a smartphone, measures and assesses muscle quantity and quality. Unfortunately for most of us, it also measures body fat percentage.
New research suggests that brain injuries may link to the development of dementia or Alzheimer's late in life. The University of California-San Francisco study looked at nearly 200,000 retired... military personnel over a decade.
Ebola outbreak in West Africa needs immediate action, says the World Health Organization. Without concerted action, there are fears the virus could spread further.
Combining digital mammography and 3D mammogram can significantly improve detection of breast cancer, study finds. The new technology could pave way to changes in how women are screened for breast... cancer.
The brains of Alzheimer's mice treated with the compound RU-505 showed less inflammation and improved blood flow than those of untreated mice. The treated mice also performed better on memory tests,... researchers report. For more than a decade, potential Alzheimer's drugs have targeted amyloid-², but, in clinical trials, they have either failed to slow the progression of the disease or caused serious side effects. However, by targeting the protein's ability to bind to a clotting agent in blood, the work in one lab offers a promising new strategy.
German study shows that the prevalence of nearsightedness increases in correlation with the level of education attained. Lead author suggests spending more time outside.
Pregnant women are at a high risk of having offspring with autism and/or developmental delay if they are exposed to pesticides based on a new study. The study has been led by researchers at the UC... Davis MIND Institute.
Individuals with severe symptoms of obsessive-compulsive disorder who do not respond well to standard OCD treatments may undergo deep brain stimulation. A 37-year-old patient with highly resistant OCD... showed improvements with the invasive treatment.
HIV infection among non-injecting drug users doubled over the last two decades, a study has found. HIV and its transmission has long been associated with injecting drug use, where hypodermic syringes... are used to administer illicit drugs. Now, a newly reported study shows that HIV infection among heterosexual non-injecting drug users (no hypodermic syringe is used; drugs are taken orally or nasally) in New York City has now surpassed HIV infection among persons who inject drugs.
Researchers have given science a new and unprecedented 3-D view of one of the most important receptors in the brain -- a receptor that allows us to learn and remember, and whose dysfunction is... involved in a wide range of neurological diseases and conditions, including Alzheimer's, Parkinson's, schizophrenia and depression.
Some cancer patients with aggressive tumors may benefit from a class of anti-inflammatory drugs used to treat rheumatoid arthritis, new research suggests. Studying triple-negative breast cancer,... researchers found that some aggressive tumors rely on an antiviral pathway that appears to drive inflammation, widely recognized for roles in cancer, rheumatoid arthritis and other inflammatory diseases.
Scientists have identified a potential Achilles’ heel for Salmonella – the bacteria’s reliance on a single food source to remain fit in the inflamed intestine.
Excessive alcohol use accounts for one in 10 deaths among working-age adults ages 20-64 years in the United States, according to a new report. Excessive alcohol use led to approximately 88,000 deaths... per year from 2006 to 2010, and shortened the lives of those who died by about 30 years. These deaths were due to health effects from drinking too much over time, such as breast cancer, liver disease, and heart disease; and health effects from drinking too much in a short period of time, such as violence, alcohol poisoning, and motor vehicle crashes.
Scientists have successfully modified the precursor to one of the drugs used to treat tuberculosis, an important first step toward new drugs that can transcend antibiotic resistance issues. In 1993,... resurging levels of tuberculosis due to this antibiotic resistance led the World Health Organization to declare it a global health emergency.
The more a child is familiar with logos and other images from fast-food restaurants, sodas and not-so-healthy snack food brands, the more likely the child is to be overweight or obese. And,... unfortunately, studies have shown that people who are overweight at a young age, tend to stay that way.
For children, stress can go a long way. A little bit provides a platform for learning, adapting and coping. But a lot of it -- chronic, toxic stress like poverty, neglect and physical abuse -- can... have lasting negative impacts. A team of researchers recently showed these kinds of stressors, experienced in early life, might be changing the parts of developing children's brains responsible for learning, memory and the processing of stress and emotion.
New study finds when a spouse, partner or parent gets chronic migraines, the whole family suffers. Some estimates say 13 percent of adults in the U.S. have migraines, and that almost 5 million in the... U.S. experience at least one migraine attack per month,
The Lassa virus, endemic to West Africa, uses an unexpected two-step process to enter cells, research has shown. The results suggest that the mechanism by which Lassa virus causes infection is more... complicated than previously known, and could lead to new approaches for preventing the disease.
More than 40 genes have been identified that predict the level of aggressiveness of melanoma and that distinguish it from other cancers with a poor prognosis, researchers report. This study is... relevant because it explains why a drug is being used to selectively attack the melanoma tumor cells. Melanoma is one of the worst, most metastatic cancers known today.
A phenomenological study offers detailed insights into homeless, alcohol-dependent patients often stigmatized by the public and policymakers as drains on the health care system, showing the... constellation of reasons they are incapable of escaping social circumstances that perpetuate and exacerbate their problems.
A high-fructose, high-fat diet can cause harmful effects to the livers of adult rats, according to new research, providing new insight into the effects of adding fructose to a Western diet high in... fat. The study showed that short-term consumption of a Western diet, rich in saturated fats and fructose, is more damaging for healthy liver development than following a high fat diet alone.
Studies have shown that smokers, in addition to exposing their lungs to harmful toxins, often eat less fruits and vegetables than non-smokers. Given the role of fruit and vegetable based antioxidants... in improving respiratory health and the difficulty of achieving lasting dietary change, researchers hypothesized that powdered fruit and vegetable supplements could improve respiratory function in heavy smokers.
A new type of tuberculosis treatment that involves manipulating the body's response to TB bacteria rather than targeting the bacteria themselves -- a concept called host-directed therapy -- has been... established by researchers. TB remains a major cause of disability and death worldwide as an estimated 8.6 million people fell ill with TB and 1.3 million people died from the disease in 2012.
A new form of neurotransmission that influences the long-lasting memory created by addictive drugs, like cocaine and opioids, and the subsequent craving for these drugs of abuse, has been discovered... by researchers. Loss of this type of neurotransmission creates changes in brains cells that resemble the changes caused by drug addiction. The findings suggest that targeting this type of neurotransmission might lead to new therapies for treating drug addiction.
As hormone levels change during the transition to menopause, the quality of a woman's cholesterol carriers degrades, leaving her at greater risk for heart disease, researchers have discovered. The... first-of-its-kind evaluation was done using an advanced method to characterize cholesterol carriers in the blood.
