Researchers determine genetic variants offering protection during the Black Death

Infectious diseases are among the strongest selective pressures in human evolution, selecting genetic variants that increase resistance to infection. In the face of a pandemic, disease resistance undergoes strong positive selection which probably affects the genetic make-up of the population thereafter. The Black Death, also known as the bubonic plague, remains the most devastating pandemic …

Without more data, a black hole’s origins can be “rotated” in any direction

An MIT study reveals that, for now, the catalog of known black hole binaries does not reveal anything fundamental about how black holes form. Pictured is a simulation of light emitted by a supermassive black hole binary system where the surrounding gas is optically thin (transparent). Credit: NASA Goddard Space Flight Center Clues to a …

Genetic variants that offered protection during the Black Death are also associated with current autoimmune disorders – Neuroscience News

Summary: People with selected variants of the ERAP2 and TICAM2 genes were 40% more likely to survive the Black Death, the researchers found. However, in modern humans, those with the ERAP2 gene are more likely to suffer from autoimmune diseases such as Crohn’s disease. Source: University of Illinois Infectious diseases are among the strongest selective …

Long-term light curve of J150052 from 2008. Credit: Cao et al, 2022 Using NASA’s Chandra and ESA’s XMM-Newton space telescopes, astronomers from Radboud University in the Netherlands and elsewhere made X-ray observations of a tidal disturbance event designated 3XMM J150052.0+015452, or J150052 for short. The results show that J150052 was triggered by a rapidly rotating …

Astronomers have just discovered the closest black hole to Earth.  Until now it was invisible

Astronomers have just discovered the closest black hole to Earth. Until now it was invisible

Astronomers have located the closest stellar-mass black hole to Earth ever discovered. Because this black hole doesn’t feed on matter or emit radiation, making it virtually invisible, scientists had to take a different approach to finding it. A star orbiting the black hole exhibited a “wobble,” which helped them locate the black hole-star binary system …

Prostate cancer and higher risk for black men

Prostate cancer and higher risk for black men

Share on PinterestExperts say black men should be screened regularly for prostate cancer. Ljuba Photo/Getty Images Researchers say family history and genetics are among the risk factors for prostate cancer in black men. Experts say the findings underscore the need for black men to get screened regularly for prostate cancer. They note that prostate cancer …

Bartmann Since 2015, the LIGO-Virgo-KAGRA collaboration has detected around 85 pairs of colliding black holes. We now know that Einstein was right: gravitational waves are generated by these systems as they wind around each other, warping spacetime …
