Neandertal gene variants both increase and decrease the risk for severe COVID-19

Last year, researchers showed that a major genetic risk factor for severe COVID-19 is inherited from Neandertals. Now the same researchers show that Neandertals also contributed a protective variant. Half of all people outside Africa carry a Neandertal gene variant that reduces the risk of needing intensive care for COVID-19 by 20 percent.

Climate change likely drove the extinction of North America's largest animals

A new study suggests that the extinction of North America's largest mammals was not driven by over-hunting by rapidly expanding human populations following their entrance into the Americas. Instead, the findings, based on a new statistical modelling approach, suggest that populations of large mammals fluctuated in response to climate change, with drastic decreases of temperatures around 13,000 years ago initiating the decline and extinction of these massive creatures.

Lemurs show there's no single formula for lasting love

Humans aren't the only mammals that form long-term bonds with a single, special mate -- some lemurs and other animals do, too. Researchers are mapping the hormone receptors that underlie these primates' ability to pair up for the long haul. Their findings suggest the brain circuitry that makes love last in some species may not be the same in others.

How a single gene alteration may have separated modern humans from predecessors

Researchers discovered a single gene alteration that may help explain cognitive differences between modern humans and our predecessor, and used that information to develop Neanderthal-like brain organoids in the lab.

Hubble uncovers concentration of small black holes

Scientists were expecting to find an intermediate-mass black hole at the heart of the globular cluster NGC 6397, but instead they found evidence of a concentration of smaller black holes lurking there. New data from the NASA/ESA Hubble Space Telescope have led to the first measurement of the extent of a collection of black holes in a core-collapsed globular cluster.

The science of siestas: New research reveals the genetic basis for daytime napping

Researchers identified 123 regions in the human genome that are associated with daytime napping and three distinct mechanisms that promote napping. Many napping-related genes also regulate other aspects of sleep.
