During COVID, scientists turn to computers to understand C4 photosynthesis

When COVID closed down their lab in March, a team from the University of Essex turned to computational approaches to understand what makes some plants better adapted to transform light and carbon dioxide into yield through photosynthesis. They published their findings in the journal Frontiers of Plant Science.

Supergene discovery leads to new knowledge of fire ants

A unique study conducted by University of Georgia entomologists led to the discovery of a distinctive supergene in fire ant colonies that determines whether young queen ants will leave their birth colony to start their own new colony or if they will join one with multiple queens.

Researchers find diverse communities comprise bacterial mats threatening coral reefs

Researchers are learning more about the brightly colored bacterial mats threatening the ecological health of coral reefs worldwide. In new research released this month, a Florida State University team revealed that these mats are more complex than scientists previously knew, opening the door for many questions about how to best protect reef ecosystems in the future.

More US Adults want the government to have a bigger role in improving peoples' lives than before the pandemic

The share of U.S. adults who support an active government role in society increased by more than 40 percent during the initial pandemic response—up from 24 percent in September 2019 to 34 percent in April 2020—according to a new national public opinion survey conducted by researchers at the Johns Hopkins Bloomberg School of Public Health and the Johns Hopkins University SNF Agora Institute.

History shows that societies collapse when leaders undermine social contracts

All good things must come to an end. Whether societies are ruled by ruthless dictators or more well-meaning representatives, they fall apart in time, with different degrees of severity. In a new paper, anthropologists examined a broad, global sample of 30 pre-modern societies. They found that when "good" governments—ones that provided goods and services for their people and did not starkly concentrate wealth and power—fell apart, they broke down more intensely than collapsing despotic regimes. And the researchers found a common thread in the collapse of good governments: leaders who undermined and broke from upholding core societal principles, morals, and ideals.
