For many people in the developing world getting enough food to eat is a persistent challenge. However the challenge does not stop there. A new issue of the international journal Energy Policy details the human and environmental cost of cooking food using the only energy source available to many people, woody biomass…
Researchers at Albert Einstein College of Medicine of Yeshiva University and Montefiore Medical Center, the University Hospital and academic medical center for Einstein, used diffusion tensor imaging, an advanced type of MRI-based imaging technique, as well as cognitive tests, to assess brain function in amateur football players…
An international team of researchers has reviewed the evidence linking exposure to atrazine - an herbicide widely used in the U.S. and more than 60 other nations - to reproductive problems in animals. The team found consistent patterns of reproductive dysfunction in amphibians, fish, reptiles and mammals exposed to the chemical. Atrazine is the second-most widely used herbicide in the U.S…
A study published in the online journal mBio® on November 29 shows that adding antibiotics to swine feed causes microorganisms in the guts of these animals to start sharing genes that could spread antibiotic resistance. Livestock farms use antibiotic drugs regularly, and not just for curing sick animals…
The immune system possesses a type of cell that can be activated by tissues within the body to remind the immune system not to attack our own molecules, cells and organs, UCSF researchers have discovered…
Researchers now understand how bacteria can break down phosphonic acids, persistent and potentially hazardous environmental pollutants found in many common medicinal products, detergents and herbicides. “We’ve achieved a critical step that has evaded other research groups for nearly 50 years,” says David Zechel, a professor in the Department of Chemistry and an expert in enzyme catalysis…
Large disparities exist in obesity and other chronic diseases across racial/ethnic groups in the United States…
Scientists have developed a new method of creating nanoporous materials with potential applications in everything from water purification to chemical sensors. In order to produce a porous material it is necessary to have multiple components. When the minor component is removed, small pores are left in its place…
The FDA has for the first time taken legal action against a dietary supplement manufacturer and owner, which has substituted ingredients and products and failed to note the changes on the final product labels. The U.S…
One of the most recent, popular supplements for athletes looking to boost performance comes in the form of a naturally-occurring amino acid called L-arginine. The reason for its popularity is twofold says Scott Forbes, a doctoral student in exercise physiology…
