Ancient origins of speed control during movement

Movement in animals is complex, especially in human beings. A variety of neurons coordinate the activity and inactivity of our muscles, and without that coordination we'd fall flat on our face when we went for a walk. Scientists have known...

Scientist develops new way to test for COVID-19 antibodies

When Dr. Stephen Smith of Seattle Children's Research Institute came down with muscle aches, gastrointestinal distress and a sudden loss of smell in late February, he suspected he had COVID-19. The testing criteria had yet to be expanded to include...

Malaria-preventive drugs dramatically reduce infections in school children

With nearly half of the world's population at risk for life-threatening malaria infections, University of Maryland School of Medicine (UMSOM) researchers and their colleagues identified an important public health measure to control the disease. Use of preventive antimalarial treatments reduces...

Researchers reveal why heat stress damages sperm

University of Oregon biologists have used the model organism Caenorhabditis elegans to identify molecular mechanisms that produce DNA damage in sperm and contribute to male infertility following exposure to heat. In humans, the optimal temperature for sperm production is just...

COVID-19 anxiety linked to body image issues

A new study has found that anxiety and stress directly linked to COVID-19 could be causing a number of body image issues amongst women and men. The research, led by Professor Viren Swami of Anglia Ruskin University (ARU) and published...

New imaging method reveals HIV’s sugary shield in unprecedented detail

Scientists from Scripps Research and Los Alamos National Laboratory have devised a method for mapping in unprecedented detail the thickets of slippery sugar molecules that help shield HIV from the immune system. Mapping these shields will give researchers a more...

New therapeutic approach against leukemia

Leukemia frequently originates from the so-called leukemic stem cell, which resides in a tumor promoting and protecting niche within the bone marrow. Scientists from the Max Planck Institute of Biochemistry in Martinsried, Germany, have found a new way to make...
