Orlando, Fla. (April 7, 2019)--Estradiol is a commonly prescribed estrogen therapy. Previous research has found that rats treated with the hormone experience an increase in sugar consumption. But according to new research, blocking the body's opioid receptors can reverse this effect. The findings will be presented today at the American Physiological Society's (APS) annual meeting at Experimental Biology 2019 in Orlando, Fla.

EAST LANSING, Mich. - Michigan State University scientists have linked a common food preservative to an altered immune response that possibly hinders flu vaccines.

The study conducted in mice, presented at the 2019 Experimental Biology meeting in Orlando, Fla., April 7 at 9 a.m., offers up a new potential factor in vaccine effectiveness.

Tert-butylhydroquinone, or tBHQ, can be found in several food products including cooking oils, frozen meats (especially fish) and processed foods such as chips and crackers. Products don't always have to include it on ingredient lists.

Orlando, Fla. (April 7, 2019) - The buildup of fat in the liver known as fatty liver disease sometimes leads to hard-to-treat liver cancer. Scientists don't understand why the cancer risk is higher for fatty liver disease caused by excessive alcohol consumption than for non-alcoholic fatty liver disease, which is associated with obesity and type 2 diabetes.

Orlando, Fla. (April 6, 2019) - Acetaminophen -- a commonly used pain reliever and fever reducer -- is the leading cause of quickly developing, or acute, liver failure in the U.S. Findings from a new mouse study suggest that treatments that increase levels of the protein thrombospondin-1 could help the liver recover from an overdose of acetaminophen.

In a collaboration between the U.S. Department of Energy's Ames Laboratory and Northeastern University, scientists have developed a model for predicting the shape of metal nanocrystals or "islands" sandwiched between or below two-dimensional (2D) materials such as graphene. The advance moves 2D quantum materials a step closer to applications in electronics.

PHILADELPHIA (April 5, 2019) -Breastfeeding is an accepted practice for millions of women worldwide and strongly endorse by the World Health Organization. To provide appropriate counseling about human milk and breastfeeding, it is important to understand cultural beliefs and customs related to the practice.

April 5, 2019 -- Even tiny amounts of gluten in foods are troublesome for people with celiac disease, and restaurants may be the hardest places to avoid the protein, finds a study by Benjamin Lebwohl, MD, MS, Celiac Disease Center at NY-Presbyterian Hospital and assistant professor of medicine and epidemiology at Columbia Mailman School. More than half of gluten-free pizza and pasta dishes in restaurants tested positive for the presence of gluten; about one-third of supposedly gluten-free foods had detectable gluten.

With new genome analysis tools, scientists have made significant advances in our understanding of modern humans' origins and ancient migrations.

But trying to find ancient DNA, let alone prove that the ancient DNA is ancestral to a population living today is extremely challenging.

On the verge of outcompeting current thin-film solar cells, perovskite solar cells seem to embody an ideal solar cell: highly efficient and low-cost - if there was not the issue of a weak long-term stability, which remains a challenge. Related to this are peculiar phenomena occurring in perovskite materials and devices, where very slow microscopic processes can furnish them with a kind of "memory effect".

A small peptide produced in the skin of predatory nematodes prevents them from cannibalizing their immediate family members, while they feed upon their close relatives, a new study finds. The ability to recognize self is an important trait and regulates many crucial biological processes. While it's observed in a wide variety of organisms, the molecular mechanisms that underlie self-recognition systems are not well understood.
