Modern humans reached westernmost Europe 5,000 years earlier than previously known

Modern humans arrived in westernmost Europe 41,000 to 38,000 years ago, about 5,000 years earlier than previously known, according to an international team of researchers that discovered stone tools used by modern humans dated to the earlier time period in a cave near the Atlantic coast of central Portugal. The tools document the presence of modern humans at a time when Neanderthals were thought to be present in the region.

Some severe COVID-19 cases linked to genetic mutations or antibodies that attack the body

Two new studies offer an explanation for why COVID-19 cases can be so variable. A subset of patients has mutations in key immunity genes; other patients have auto-antibodies that target the same components of the immune system. Both circumstances could contribute to severe forms of the disease.

Ancient volcanoes once boosted ocean carbon, but humans are now far outpacing them

A new study of an ancient period that is considered the closest natural analog to the era of modern human carbon emissions has found that massive volcanism sent great waves of carbon into the oceans over thousands of years -- but that nature did not come close to matching what humans are doing today.

Possible marker of life spotted on venus

Astronomers have discovered a rare molecule -- phosphine -- in the clouds of Venus. On Earth, this gas is only made industrially or by microbes that thrive in oxygen-free environments. Astronomers have speculated for decades that high clouds on Venus could offer a home for microbes -- floating free of the scorching surface but needing to tolerate very high acidity. The detection of phosphine could point to such extra-terrestrial 'aerial' life.

High-fidelity record of Earth's climate history puts current changes in context

Scientists have compiled a continuous, high-fidelity record of variations in Earth's climate extending 66 million years into the past. The record reveals four distinctive climate states, which the researchers dubbed Hothouse, Warmhouse, Coolhouse, and Icehouse. These major climate states persisted for millions and sometimes tens of millions of years, and within each one the climate shows rhythmic variations corresponding to changes in Earth's orbit around the sun.

New Hubble data suggests there is an ingredient missing from current dark matter theories

Recent observations have found that something may be missing from the theories of how dark matter behaves. This missing ingredient may explain why researchers have uncovered an unexpected discrepancy between observations of the dark matter concentrations in a sample of massive galaxy clusters and theoretical computer simulations of how dark matter should be distributed in clusters.

How coronavirus took hold in North America and in Europe

Early interventions were effective at stamping out coronavirus infections before they spread, according to a new study. Combining virus genomics with epidemiologic simulations and travel records, the research shows that in both the United States and in Europe, sustained transmission networks became established only after separate introductions of the virus that went undetected.
