Does Biden’s American Jobs Plan go big enough on climate change? – Al Jazeera English

At first glance, United States President Joe Biden’s giant American Jobs Plan seems like an environmentalist’s dream: enormous investment in electric vehicles, big tax incentives for renewable energy and widespread improvements to the ailing US power grid. The initiative would…

Does selfishness evolve? Ask a cannibal

(Rice University) Biologists have used one of nature’s most prolific cannibals to show how social structure affects the evolution of selfish behavior. Researchers showed they could drive the evolution of less selfish behavior in Indian meal moths with habitat changes that forced larval caterpillars to interact more often with siblings.

How Global Warming Could Make Food Less Safe To Eat – Mashed

Scientists say global warming could make leafy greens even riskier. The lettuce in the 2018 case, was contaminated by water from an irrigation canal that ran next to a cattle feedlot (via Eater). That canal appeared to be the link…

Tropical species are moving northward in U.S. as winters warm

(University of California – Berkeley) Climate change is reducing the number of sub-freezing days over much of the American South, providing an opportunity for cold-sensitive tropical species — mammals, reptiles, amphibians, insects, trees, shrubs and grasses — to move northward, potentially displacing temperate species. Mosquitoes could bring infectious diseases farther north. The southern pine beetle is already moving north and devastating pine forests. While some may welcome manatees and sea turtles, few look forward to the spread of Burmese pythons.

In a leap for battery research, machine learning gets scientific smarts

(DOE/SLAC National Accelerator Laboratory) Researchers combined machine learning with knowledge gained from experiments and equations guided by physics to discover and explain a process that shortens the lifetimes of fast-charging lithium-ion batteries.

A COSMIC approach to nanoscale science

(DOE/Lawrence Berkeley National Laboratory) COSMIC, a multipurpose X-ray instrument at Berkeley Lab’s Advanced Light Source, has made headway in the scientific community since its launch less than 2 years ago, with groundbreaking contributions in fields ranging from batteries to biominerals.

New fossil discovery illuminates the lives of the earliest primates

(Advanced Science Research Center, GC/CUNY) A new fossil discovery is central to primate ancestry and adds to our understanding of how life on land recovered after the Cretaceous-Paleogene extinction event 66 million years ago that wiped out all dinosaurs, except for birds. This study was documented in a paper published in the journal Royal Society Open Science.

Scientists describe earliest primate fossils

(University of Washington) A new study published Feb. 24, 2021 in the journal Royal Society Open Science documents the earliest-known fossil evidence of primates. These creatures lived less than 150,000 years after the Cretaceous-Paleogene mass extinction event that killed off non-avian dinosaurs and saw the rise of mammals.

Biden Wants to Take On China and Climate Change at the Same Time – Slate

Global warming is, in large part, a U.S.-China problem. The two countries combined account for 43 percent of worldwide CO2 emissions. The decisions the two countries make in the coming years will shape what life is like on the planet…
