Column: How 2.8 million California voters nearly banned gay teachers from public schools

Sally Miller Gearhart’s death is a reminder of an era that seems both terribly remote and shockingly recent. Gearhart was a radical feminist separatist, a communications professor, a Bay Area force of nature, a writer and outspoken gay rights activist. In the 1970s, she published a science-fiction novel about women living apart from men in a rural feminist utopia. In the 1980s, she championed real-life technologies that might allow women to have babies — girl babies — without the meddling of men. “Crackpottery,” this newspaper called it.

137 human genomes from the Middle East fill gaps in human history

Whole-genome sequencing efforts around the world have offered important insights into human diversity, historical migrations, and the relationships between people of different regions—but scientists still don't have a complete picture because some regions and people remain understudied. A new study reported in the journal Cell on August 4 helps to fill one of these big gaps by generating more than 100 high-coverage genome sequences from eight Middle Eastern populations using linked-read sequencing.

Comprehensive study of Middle Eastern DNA reveals ancient human adaptation to agriculture, climate change

The most comprehensive study so far of genetic diversity in the Middle East has given a glimpse into the lives of ancient humans who lived through such seismic events as the development of agriculture and the formation of the Arabian Desert. Researchers at the Wellcome Sanger Institute and their collaborators uncovered signals in DNA that indicate a population boom in the Levant coinciding with the transition to agriculture and a population crash in Arabia as the region dried up.

Biden rebukes GOP governors for barring mask mandates

President Biden on Tuesday rebuked Republican governors who have imposed bans on mask mandates and pleaded with them to “get out of the way” of businesses and schools that want to impose coronavirus-related requirements. “We need leadership from everyone and if some governors aren’t willing to do the right thing...

Markings in Spanish Cave Made by Neanderthals

CUEVA DE ARDALES, SPAIN—According to a statement released by the French National Centre for Scientific Research (CNRS)), a team led by University of Bordeaux archaeologist Franceso d’Errico has found that red markings in Spain’s Cueva de Ardales were intentionally painted more than 65,000 years ago. Scholars had previously argued that the markings were a natural deposit of iron oxide left by flowing water. But the team found that the red residue did not match other iron oxide deposits in the cave and were deliberately made by Neanderthals, who were the only inhabitants of this part of Europe when the marks were made. The team also found evidence that the markings were left over the course of thousands of years, suggesting many generations of Neanderthals visited the cave to make paintings.

Neanderthal markings in Spain suggest cave art, study says

Red markings on a stalagmite dome in a cave system in southern Spain were created by Neanderthals more than 60,000 years ago, a new study says. The staining was applied by a process of splattering and blowing about 20,000 years before modern humans arrived in Europe, the research suggests. An...

65,000-Year-Old Cave Markings Made by Neanderthals: Study

An analysis concludes that pigments were transported into the cave, and the marks were made with intention, though their ultimate meaning remains unknown. Neanderthals were making their mark on caves long before modern humans came to Europe. A paper published Monday (August 2) in PNAS confirms that red ochre markings on structures inside the famed Cueva de Ardales in Málaga, Spain were created intentionally and were not naturally occurring as some thought.

How climate change thousands of years ago left traces in Middle East's DNA

Migration and climate change thousands of years ago left a lasting trace in the DNA of people from the Middle East, a study has shown. The findings, published on Thursday in Cell, offer a fascinating insight into how humans spread across the Middle East after they arrived in the region from Africa about 50,000 years ago.

The Right Tool for the Job

Some might wonder why prehistoric cave drawings weren’t more detailed. Surely there were artists capable of rendering intricate representations of the circulatory system of aurochs or the dentition of a Saber Tooth Tiger drawn to scale. But what we see on these cave walls are stick figure men chasing antelope-shaped...

Variants May Predict Which Young People Are at Risk for Severe COVID-19

While people carry mostly the same genes, there are many small changes in the sequences of those genes, and small variations throughout the genome that can add up to have huge biological effects. Since the beginning of the pandemic, researchers have been trying to determine why some people experience more severe COVID-19 cases than others. There may be many reasons, such as pre-existing health conditions, or age. But genetics may help explain why some young, healthy people end up with serious health problems when most other young people do not.

“Pictures” of Neanderthals found in a Spanish cave

“Pictures” of Neanderthals found in a Spanish cave. Scientists have found new evidence that the Neanderthals had a very high level of development. Research has shown that the rock art in the Spanish cave Cueva de Ardales was created by them, according to PNAS . Pigmented stalagmites were discovered back...
