A giant saber-toothed cat lived in North America between 5 million and 9 million years ago, weighing up to 900 pounds and hunting prey that likely weighed 1,000 to 2,000 pounds, scientists reported today in a new study. Columbus, May 04, 2021.- The researchers completed a painstaking comparison of sevenContinuar Leyendo

A new study led by University of Minnesota astrophysicists shows that high-energy light from small galaxies may have played a key role in the early evolution of the Universe. The research gives insight into how the Universe became reionized, a problem that astronomers have been trying to solve for years.Continuar Leyendo

Researchers at Karolinska Institutet in Sweden have discovered a mechanism through which meningitis-causing bacteria can evade our immune system. In laboratory tests, they found that Streptococcus pneumoniae and Haemophilus influenzae respond to increasing temperatures by producing safeguards that keep them from getting killed. This may prime their defenses against ourContinuar Leyendo

Mitochondria are the energy suppliers of our body cells. These tiny cell components have their own genetic material, which triggers an inflammatory response when released into the interior of the cell. The reasons for the release are not yet known, but some cardiac and neurodegenerative diseases as well as theContinuar Leyendo

Researchers in Japan have compiled a first-of-its-kind genetic database for autoimmune and autoinflammatory diseases. This resource will allow experts to more deeply understand how immune disorders develop and plan future drug discovery projects. Scientists also hope this atlas of immune-related genome data may eventually be applied to investigations of infectiousContinuar Leyendo

The Mayo Clinic data scientists who developed highly accurate computer modeling to predict trends for COVID-19 cases nationwide have new research that shows how important a high rate of vaccination is to reducing case numbers and controlling the pandemic. Minneapolis, April 30, 2021.- Vaccination is making a striking difference inContinuar Leyendo

A higher ratio of green spaces at the county level is associated with a lower racial disparity in coronavirus infection rates, according to a new study. It is the first study to report the significant relationship between the supply of green spaces and reduced disparity in infectious disease rates. Champaign,Continuar Leyendo

Arum Han, professor in the Department of Electrical and Computer Engineering at Texas A&M University, and his collaborators have designed an experimental system that shows exposure of SARS-CoV-2 to a very high temperature, even if applied for less than a second, can be sufficient to neutralize the virus so thatContinuar Leyendo
