Experts in in-vitro fertilization (IVF) have discovered a pattern of protein secretion during egg maturation that they say has the possibility of leading to a new, non-invasive test to evaluate the fitness of eggs before they are fertilized in the clinic.
A novel study answers age-old questions about how cancers spread by applying tools from evolutionary biology. The new insights will help scientists better understand the genetic origins of tumor metastases, and lead to more effective targets for treatment, said the researchers.
Contrary to the words immortalized by the piano singer in “Casablanca,” a sigh is far more than a sigh. Heaving an unconscious sigh is a life-sustaining reflex that helps preserve lung function.
When buildings collapse in future disasters, the hero helping rescue trapped people may be a robotic cockroach.
A new study strengthens evidence that sleep problems put women at higher risk for developing Type 2 diabetes.
The HSE autoclavable organ chamber allows for longer term studies that have previously been challenging due to sterility issues. The chamber itself, cover, connecting parts, heat exchanger and optional oxygenator are all autoclavable.
Researchers have identified a faulty signaling pathway that, when corrected in mice, ameliorates the symptoms of Rett syndrome, a devastating neurological condition. The findings could lead to the discovery of compounds or drugs that may benefit children affected by the disease.
Elastin is a crucial building block in our bodies. Its flexibility allows skin to stretch and twist, blood vessels to expand and relax with every heartbeat, and lungs to swell and contract with each breath. But exactly how this protein-based tissue assembles itself to achieve this flexibility remained an unsolved question — until now.
Two years ago, Ellen Martinsen, was collecting mosquitoes at the Smithsonian's National Zoo, looking for malaria that might infect birds--when she discovered something strange: a DNA profile, from parasites in the mosquitoes, that she couldn't identify.
President Barack Obama is asking Congress for more than $1.8 billion in emergency funding to help fight the Zika virus. In an announcement Monday, the White House said the money would be used to expand mosquito control programs, speed development of a vaccine, develop diagnostic tests and improve support for low-income pregnant women.
Race should no longer be used as a distinguishing factor in human biology and genetics research, contends a new paper in Science.
Ebola and now Zika are two viruses that have monopolized headlines for two years. But the Middle East respiratory syndrome is a potentially deadly contagion also on the radar of health officials worldwide. Some 1,500 people have been infected, and more than 500 have been killed.
