The New York Times reports: While some African elephants parade across the savanna and thrill tourists on safari, others are more discreet. They stay hidden in the forests, eating fruit. “You feel pretty lucky when you catch sight of them,” said Kathleen Gobush, a Seattle-based conservation biologist and member of the African Elephant Specialist Group… Read More »
Ben Ehrenreich writes: On January 13, one week before the inauguration of Joe Biden as the forty-sixth president of the United States and seven long days after the storming of the Capitol by an armed right-wing mob, it was easy enough to miss an article published in the journal Frontiers in Conservation Science, despite its… Read More »
Ruth DeFries writes: Sometime in the first billion years of the planet’s 4.5-billion-year history, a cell emerged in a primordial stew of chemicals brewing in liquid water. At that moment, the predictable chemistry and physics of the early Earth gave way to seething, roiling complexity. Primitive life thrived in the deep sea, where underwater volcanoes… Read More »
AI promises to make life easier, but what will humans lose in the bargain? AP Photo/Frank Augstein By Nir Eisikovits, University of Massachusetts Boston and Dan Feldman, University of Massachusetts Boston The history of humans’ use of technology has always been a history of coevolution.

Shannon Stirone writes: There’s no place like home—unless you’re Elon Musk. A prototype of SpaceX’s Starship, which may someday send humans to Mars, is, according to Musk, likely to launch soon, possibly within the coming days. But what motivates Musk? Why bother with Mars? A video clip from an interview Musk gave in 2019 seems… Read More »
The Guardian reports: Rivers in which fish populations have escaped serious damage from human activities make up just 14% of the world’s river basin area, according to the most comprehensive study to date. Scientists found that the biodiversity of more than half of rivers had been profoundly affected, with big fish such as sturgeon replaced… Read More »

Piyush Nanda writes: In an area devastated by deforestation, an 18-month-old toddler from the nearest settlement, Meliandou in Guinea, was seen playing around a fallen tree swarming with bats. The child then contracted a mysterious illness, which spread to many who came in contact. After it had already killed 30 people, the illness was identified… Read More »
Matt Simon writes: As California’s economy skyrocketed during the 20th century, its land headed in the opposite direction. A booming agricultural industry in the state’s San Joaquin Valley, combined with punishing droughts, led to the over-extraction of water from aquifers. Like huge, empty water bottles, the aquifers crumpled, a phenomenon geologists call subsidence. By 1970,… Read More »
The Guardian reports: Insect populations are suffering “death by a thousand cuts”, with many falling at “frightening” rates that are “tearing apart the tapestry of life”, according to scientists behind a new volume of studies. The insects face multiple, overlapping threats including the destruction of wild habitats for farming, urbanisation, pesticides and light pollution. Population… Read More »
ScienceAlert reports: All of the Amazon’s splendid greenery. Every fish in the Pacific. Every microbe underfoot. Every elephant on the plains, every flower, fungus, and fruit-fly in the fields, no longer outweighs the sheer amount of stuff humans have made. Estimates on the total mass of human-made material suggest 2020 is the year we overtake… Read More »
Jessica Flack and Cade Massey write: In Philip K Dick’s classic science fiction novel Ubik, one of the main characters, Runciter, is in charge of assembling a team of individuals called ‘inertials’. The hope is that they will counteract the power of ‘precogs’ and ‘telepaths’, recruited by corporations to carry out espionage and other nefarious… Read More »
Bret Stetka writes: In 1959, Dmitri Belyaev made his way to Siberia to look for the most polite foxes he could find. A Soviet geneticist, Belyaev was interested in how animal domestication occurs — and in what happens biologically when the wild canine evolves into the mild-mannered dog. The thousands of fox fur farms stippling… Read More »
Dirk Philipsen writes: A basic truth is once again trying to break through the agony of worldwide pandemic and the enduring inhumanity of racist oppression. Healthcare workers risking their lives for others, mutual aid networks empowering neighbourhoods, farmers delivering food to quarantined customers, mothers forming lines to protect youth from police violence: we’re in this… Read More »
Scott Hershberger writes: The late esteemed English actor Christopher Lee traced his ancestry directly to Charlemagne. In 2010 Lee released a symphonic metal album paying homage to the first Holy Roman emperor—but his enthusiasm may have been a tad excessive. After all, says geneticist Adam Rutherford, “literally everyone” with European ancestry is directly descended from… Read More »
By Karen L. Kramer, Sapiens, June 9, 2020 Something curious happened in human population history over the last 1 million years. First, our numbers fell to as low as 18,500, and our ancestors were more endangered than chimpanzees and gorillas. Then we bounced back to extraordinary levels, far surpassing the other great apes. Today the… Read More »
