An enzyme found in fat tissue in the centre of our bones helps control the production of new bone and fat cells, shows a study in mice published today in eLife.

The findings may help scientists better understand how the body maintains fat stores and bone production in response to changing conditions, such as during aging. They may also suggest new approaches to treating conditions that cause bone loss in older adults.

DETROIT - Jessica Damoiseaux, Ph.D., an associate professor with the Institute of Gerontology at Wayne State University, recently published the results of a three-year study of cognitive changes in older adults. The team followed 69 primarily African American females, ages 50 to 85, who complained that their cognitive ability was worsening though clinical assessments showed no impairments. Three magnetic resonance imaging scans (MRIs) at 18-month intervals showed significant changes in functional connectivity in two areas of the brain.

(Boston)--Lung cancer remains the leading cause of cancer-related deaths. Non-small cell lung cancer (NSCLC) accounts for 80-85 percent cases of lung cancer and when diagnosed early, has a five-year survival rate of 50-80 percent. Black patients have lower overall incidence of NSCLC than white patients, but are more likely to be diagnosed at later stages. They also are less likely to receive surgery for early-stage cancer.

PROVIDENCE, R.I. [Brown University] -- What motivated Americans to wear masks and stay socially distanced (or not) at the beginning of the COVID-19 pandemic? More often than not, it was partisanship, rather than perceived or actual health risk, that drove their behavior, according to a new study co-authored by researchers at Brown University.

New research published in the Journal of Medicinal Food suggests eating prunes each day can improve risk factors for cardiovascular disease (CVD) including raising antioxidant capacity and reducing inflammation among healthy, postmenopausal women.

Cardiovascular disease is the number one cause of death worldwide posing a significant public health challenge.

The research led by San Diego State University reveals that prunes can positively affect heart disease risk.

Almost all cells in our body contain a nucleus: a somewhat spherical structure that is separated from the rest of the cell by a membrane. Each nucleus contains all the genetic information of the human being. So it serves as a kind of library - but one with strict requirements: If the cell needs the building instructions for a protein, it won't simply borrow the original information. Instead, a transcript of it is made in the nucleus.

The most comprehensive molecular study to date of the brains of people who died of COVID-19 turned up unmistakable signs of inflammation and impaired brain circuits.

Investigators at the Stanford School of Medicine and Saarland University in Germany report that what they saw looks a lot like what's observed in the brains of people who died of neurodegenerative conditions such as Alzheimer's disease and Parkinson's disease.

If only it were as simple as finding more grassland for an antelope.

The story of efforts to conserve the endangered oribi in South Africa represent a diaspora of issues as varied as the people who live there. On its surface, like many threatened species, you have conflict between a need for habitat and private landownership.

Legend has it that Marie Antoinette's hair turned gray overnight just before her beheading in 1791.

Though the legend is inaccurate--hair that has already grown out of the follicle does not change color--a new study from researchers at Columbia University Vagelos College of Physicians and Surgeons is the first to offer quantitative evidence linking psychological stress to graying hair in people.

Looking for better ways to treat patients with esophageal cancer, University of Colorado Cancer Center member Martin McCarter, MD, is investigating whether a new treatment sequence will result in better outcomes.

Managing type 2 diabetes typically involves losing weight, exercise and medication, but new research by Dr. Makoto Fukuda and colleagues at Baylor College of Medicine and other institutions suggests that there may be other ways to control the condition through the brain. The researchers have discovered a mechanism in a small area of the brain that regulates whole-body glucose balance without affecting body weight, which suggests the possibility that modulating the mechanism might help keep blood sugar levels in a healthy range.

BINGHAMTON, N.Y. -- Political institutions such as the timing of elections and presidentialism had a larger influence on COVID-19 strategies than the institutions organizing national healthcare, according to a research team led by a professor at Binghamton University, State University of New York.

If you listen to songbirds, you will recognize repeated melodies or phrases. Each phrase is made up of distinct sounds, strung together. A study from researchers at McGill University has found that the song phrases of many songbird species follow patterns that are similar to those used in human speech. At least in some respects.

RIVERSIDE, Calif. -- Communities surrounding the Salton Sea, the inland body of water straddling California's Riverside and Imperial counties, show high rates of asthma due, possibly, to high aerosol dust levels resulting from the sea shrinking over time.

Scientists suspect, however, the Salton Sea plays an additional role in pulmonary health.

In a first-of-its-kind study in the world conducted at Tel Aviv University, researchers found that water generated from the air in the heart of an urban area, the city of Tel Aviv, complied with all of the strict drinking water standards set both by the State of Israel and by the World Health Organization. The researchers examined the quality of the water produced from the water vapor in the urban atmosphere, which is characterized by industry and massive construction, and found that it was suitable for drinking.
