Bacteria, often synonymous with infection and disease, may have an unfair reputation. Research indicates there are as many, if not more, bacterial cells in our bodies as human cells, meaning they play an important role in our physiology (1). In fact, a growing body of evidence shows that greater gut microbiota diversity (the number of different species and evenness of these species' populations) is related to better health.

Feb. 15, 2019--Adults with obstructive sleep apnea (OSA) who experience excessive sleepiness while awake appear to be at far greater risk for cardiovascular diseases than those without excessive daytime sleepiness, according to new research published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.

Researchers have uncovered new evidence about the agriculturally important process of vernalization in a development that could help farmers deal with financially damaging weather fluctuations.

Vernalization is the process by which plants require prolonged exposure to cold temperature before they transition from the vegetative state to flower. For decades it's been a key focus of research into plant development and crop productivity.

PHILADELPHIA - Offering compensation can be an important tactic to attract potential participants for enrollment in research studies, but it might come at a cost. A new study conducted by researchers in the Perelman School of Medicine at the University of Pennsylvania found that up to 23 percent of respondents lied about their eligibility to participate in a survey when offered payment, even small amounts.

WASHINGTON, D.C. -- The vast majority of Americans are paying attention to reducing food waste with the oldest being the most cognizant, according to the latest Michigan State University (MSU) Food Literacy and Engagement Poll.

Risk Analysis, An International Journal has published a special issue, "Social Science of Automated Driving," which features several articles examining the human side of automated driving, focusing on questions about morality, the role of feeling, trust and risk perceptions.

COLUMBUS, Ohio - A woman whose boyfriend or husband regularly watches pornography is more likely to report symptoms of an eating disorder, new research suggests.

The study is one of the first to look at how a romantic partner's behavior might be linked to the likelihood of a woman experiencing or engaging in such things as extreme guilt about eating, preoccupation with body fat, binging or purging.

Exposure to glyphosate — the world’s most widely used, broad-spectrum herbicide and the primary ingredient in the weedkiller Roundup — increases the risk of some cancers by more than 40 percent, according to new research from the University of Washington.

Various reviews and international assessments have come to different conclusions about whether glyphosate leads to cancer in humans.

The option to measure the gravitational waves of two merging neutron stars has offered the chance to answer some of the fundamental questions about the structure of matter. At the extremely high temperatures and densities in the merger scientists conjecture a phase-transition where neutrons dissolve into their constituents: quarks and gluons. In the current issue of Physical Review Letters, two international research groups report on their calculations of what the signature of such a phase transition in a gravitational wave would look like.

Researchers say they are closer to solving the mystery of how a good night's sleep protects against heart disease. In studies using mice, they discovered a previously unknown mechanism between the brain, bone marrow, and blood vessels that appears to protect against the development of atherosclerosis, or hardening of the arteries--but only when sleep is healthy and sound. The study, funded by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health, will appear in the journal Nature.
