In what likely is the first study on the evolution of dietary preferences across the animal kingdom, UA researchers report several unexpected discoveries, including that the first animal likely was a carnivore and that humans, along with other omnivores, belong to a rare breed.
Over the last day, winds outside of Tropical Storm Chantal have been weakening the storm in the North Atlantic Ocean. When NASA's Aqua satellite passed over the storm from its orbit in space on Aug. 22, 2019, the storm had weakened to a depression and strongest storms were still confined to the northeast of the center.
Researchers at Binghamton University, State University of New York have discovered the mechanism through which ultraviolet radiation, given off by the sun, damages our skin.
For the first time, scientists built a synthetic biologic system with compartments like real cells. This Army project at the University of Massachusetts Amherst could lead to materials that provide new avenues to deliver medicine, treat wounds and purify water for Soldiers.
Just when international fears of contracting Zika began to fade in 2017, an undetected outbreak was peaking in Cuba -- a mere 300 miles off the coast of Miami. A team of scientists at Scripps Research, working in concert with several other organizations, uncovered the hidden outbreak by overlaying air-travel patterns with genomic sequencing of virus samples from infected travelers. The discovery is featured on the cover of the Aug. 22, 2019 issue of Cell.
Light touch plays a critical role in everyday tasks, such as picking up a glass or playing a musical instrument, as well as for detecting the touch of, say, biting insects. Salk researchers have discovered how neurons in the spinal cord help transmit such itch signals to the brain. The findings could help contribute to a better understanding of itch and could lead to new drugs to treat chronic itch, which occurs in such conditions as eczema, diabetes and even some cancers.
A group of researchers may have found a way to reverse falling crop yields caused by increasingly salty farmlands throughout the world. Brigham Young University scientists have used bacteria found in the roots of salt-tolerant plants to successfully inoculate alfalfa plants against overly salty soil.
The function of the visual photopigment rhodopsin and its action in the retina to facilitate vision is well understood. However, there remain questions about other biological functions of this family of proteins (opsins) and this has ramifications for our understanding of several evolutionary pathways. Now, an international research team led by the University of Göttingen has shown there are other functions of opsin outside vision and this provides insights into how the eye evolved. Their research was published in Current Biology.
a research team at Harvard's Wyss Institute for Biologically Inspired Engineering and the Massachusetts Institute of Technology (MIT) demonstrates the use of CRISPR as a control element in a new type of stimuli-responsive "smart" materials.
