Climate change and predator-prey dynamics with wolves make for smaller moose. Ecologists compare skull measurements spanning four decades gathered at Isle Royale National Park. For the booming moose population of Isle Royale, a key species in the world's longest running predator-prey study on the island, skulls have shrunk by about 16 percent over a 40-year period.
A spoonful of sugar may make the medicine go down, but understanding what happens to that sugar in the cell is far more complicated than simple digestion, according to researchers.
Researchers from Columbia University Medical Center tested a method to reduce the adverse effects of evening ambient light exposure, while still allowing use of blue light-emitting devices.
New research from psychologists and health professionals in Swansea has found that the types of life values that patients hold affect their attendance at medical treatment for pelvic-floor dysfunction, a condition affecting over 25 percent of all women in the UK.
One in two persons aged 65 and above has suboptimal levels of vitamin D in the blood. This is the conclusion of an investigation conducted by researchers at the Helmholtz Zentrum München, as part of the population-based KORA-Age study in the region of Augsburg. Moreover, as the authors of the study report in the peer-reviewed journal Nutrients, one in four older adults has suboptimal vitamin B12 levels.
Researchers at Scripps Institution of Oceanography at the University of California San Diego have made a discovery with potential human health impacts in a parchment tubeworm, found to have ferritin with the fastest catalytic performance ever described.
Researchers at the University of Colorado Anschutz Medical Campus have discovered that color vision in mice is far more complex than originally thought, opening the door to experiments that could potentially lead to new treatments for humans.
In the past decade, the first cases of respiratory tract infection caused by bat-borne Pteropine ortheovirus (PRV) have been reporting in humans. To help shed light on the clinical course of PRV infection, researchers reporting in PLOS Neglected Tropical Diseases have now used a mouse model of the infection to study its virulence, pathology and pathogenesis.
Researchers have found a new potential treatment that may alleviate complications of babies born smaller than they should be, also called fetal growth restriction, which refers to poor growth of the fetus in the mother's womb during pregnancy. The findings were published in The Journal of Physiology.
Micro-grippers may be able to navigate unstructured environments and could help reduce risk during surgeries, according to a study published Dec. 13, 2017, in the open-access journal PLOS ONE by Federico Ongaro from the University of Twente, The Netherlands and colleagues.
