In a new study, Hao Yan, director of the Center for Molecular Design and Biomimetics at Arizona State University's Biodesign Institute presents a clever means of localizing and confining enzymes and the substrate molecules they bind with, speeding up reactions essential for life processes.
Considerably more of the fossil record of creatures such as mammoths, mastodons, camels, horses and ground sloths has been lost in what is now the continental United States and South America than in Alaska and areas near the Bering Strait.
Recently, a new mutation signature found in cancer cells was suspected to have been created by a family of enzymes found in human cells called the APOBEC3 family. The study, 'Strand-biased Cytosine deamination at the Replication Fork causes Cytosine to Thymine Mutations in Escherichia coli,' led by Ashok Bhagwat, Ph.D., professor of chemistry in the College of Liberal Arts and Sciences at Wayne State University, was recently published in the Proceedings of the National Academy of Sciences.
University of Alberta researchers have developed a method of connecting neurons, using ultrashort laser pulses -- a breakthrough technique that opens the door to new medical research and treatment opportunities. Neurons are cells in the nervous system that are responsible for transferring information between the brain and the rest of the body. The team is the first ever to find a way to bond neurons and in doing so, is giving researchers a powerful new tool.
A percentage of harmful aerosols in the atmospheric boundary layer over Moscow is gradually lowering, meteorologists of the Lomonosov Moscow State University stated. Nonetheless, aerosols still influence a local climate significantly.
The long-term damage of levees can be far worse for those living behind them than if those levees were not there, a UC Davis case study of the Sny Island levee district found.
Raising insects for research can be difficult because members of many species are picky eaters, but Canadian entomologists have found a solution for rearing moths and possibly other insects.
Bombus occidentalis used to be the most common bumble bee species in the Pacific Northwest, but in the mid 1990s it became one of the rarest. Now, according to an article in the Journal of Insect Science offers, it may be making a comeback.
Columbia Theological Seminary's William Brown, the William Marcellus McPheeters Professor of Old Testament, will present a paper at the AAAS 2016 Annual Meeting on 'Theological Reasons for Protecting Biodiversity.' The talk will be presented on Saturday, Feb. 13, 2016 at 10:00 AM-11:30 AM at the Marriott Wardman Park. Prof. Brown will present how Columbia Seminary is cultivating a love for biodiversity among religious leaders through the help of the AAAS 'Science for Seminaries' program.
Low-income families with children who have special health care needs are at high risk for food insecurity, even when they receive Supplemental Security Income (SSI) and participate in public assistance programs, such as Supplemental Nutrition Assistance Program (SNAP) and Women, Infants, and Children (WIC).
