CHAMPAIGN, Ill. -- The microbes that inhabit our bodies are influenced by what we eat, drink, breathe and absorb through our skin, and most of us are chronically exposed to natural and human-made environmental contaminants. In a new paper, scientists from the University of Illinois at Urbana-Champaign review the research linking dozens of environmental chemicals to changes in the gut microbiome and associated health challenges.
The review is published in the journal Toxicological Sciences.
Rice has always been the most important food in Asia and the world. About half of the population on earth use rice as their main food source. The origin, spread, evolution, and ecological adaptation of cultivated rice are still one of the most important issues which currently concerned by global archaeologists, biologists, and agricultural scientists.
DURHAM, N.C. - Engineers at Duke University and the New York University's Tandon School of Engineering have demonstrated a method for ensuring that an increasingly popular method of genetic identification called "DNA fingerprinting" remains secure against inadvertent mistakes or malicious attacks in the field.
HAMILTON, ON (May 20, 2020) -A huge study of more than 160,000 people in 21 countries has found that women are less likely to have cardiovascular disease, and die of it, than men.
It didn't matter if women had, or didn't have, a previous heart attack or stroke. It also didn't matter where they lived around the world, nor their economic status.
The COVID-19 pandemic is stressful enough, but for children and adults with autism spectrum disorder (ASD) and their families, the crisis can be especially difficult.
Adrien A. Eshraghi, M.D., M.Sc., professor of Otolaryngology, Neurological Surgery and Biomedical Engineering, has dedicated much of his career to caring for individuals with various disabilities including individuals with autism, who are very dear to him.
A team of scientists from Hollings Cancer Center at the Medical University of South Carolina (MUSC) has developed a novel flow cytometry technique that can, for the first-time, quantify protein production in T-cells. T cells are immune cells that surveil the body and can effectively target and kill cancer cells. However, when T cells are in the vicinity of a tumor, cancer cells sap their energy, leading to a decrease in their protein production.
Before there were animals, bacteria or even DNA on Earth, self-replicating molecules were slowly evolving their way from simple matter to life beneath a constant shower of energetic particles from space.
In a new paper, a Stanford professor and a former post-doctoral scholar speculate that this interaction between ancient proto-organisms and cosmic rays may be responsible for a crucial structural preference, called chirality, in biological molecules. If their idea is correct, it suggests that all life throughout the universe could share the same chiral preference.
Clinician burnout is a growing public health concern, with the National Academy of Sciences reporting that 35-54% of U.S. nurses and physicians exhibit substantial symptoms of burnout.
Photosystem II is a protein complex in plants, algae and cyanobacteria that is responsible for splitting water and producing the oxygen we breathe. Over the past few years, an international collaboration between scientists at the Department of Energy's Lawrence Berkeley National Laboratory, SLAC National Accelerator Laboratory and several other institutions have been able to observe various steps of this water-splitting cycle at the temperature at which it occurs in nature.
Shortly after the explosion in microcephaly cases caused by Zika virus in Brazil in 2015-16, several scientific studies were published with evidence that the pathogen is capable of crossing the human placenta, the organ that keeps the fetus connected to the mother's body during pregnancy. From then on, the states began following a protocol established by the National Ministry of Health requiring collection of placental samples to help diagnose the disease in women with symptoms during pregnancy.
