A little more sexy time for symbionts could help coral reefs survive the trials of climate change. And that, in turn, could help us all.

Sea ice in the Arctic appears to have hit its annual minimum extent on Sept. 16, after waning in the 2021 Northern Hemisphere spring and summer. The summertime extent is the 12th-lowest in the satellite record, according to scientists at the NASA-supported National Snow and Ice Data Center and NASA.
Root, tuber and banana (RT&B) crops are widely cultivated across the landscapes of sub-Saharan Africa (SSA). These staple food crops play a fundamental role in smallholder farming systems due to their good economic value and high importance within the daily diets of most households. The extensive planting of RT&B crops highlights their adaptive nature, but a team of researchers has identified a...
There's a global race to reduce the amount of harmful gases in our atmosphere to slow down the pace of climate change, and one way to do that is through carbon capture and sequestration—sucking carbon out of the air and burying it. At this point, however, we're capturing only a fraction of the carbon needed to make any kind of dent in climate change.
A team of Omani cavers has made what is believed to be the first descent to the bottom of Yemen's fabled Well of Barhout—a natural wonder shunned by many locals, who believe it is a prison for genies.
A study conducted at the University of São Paulo (USP) in Brazil, and reported in an article published in the journal Conservation Letters, shows that destruction of the Atlantic Rainforest increases in election years.
Examining the practices landlords use to screen potential tenants can offer significant insights into how racism continues to shape life outcomes. While sociological research on racial discrimination in housing has increasingly highlighted the key role that landlords play as gatekeepers to rental housing markets, this research has largely been operating under the fundamental assumption that...
Colorism is a form of discrimination, typically within a racial or ethnic group, favoring people with lighter skin over those with darker skin. This pernicious form of discrimination is often overshadowed in discussions about racism, but it affects a broad swath of people across multiple populations.
In the framework of an international research project, a team of scientists have demonstrated for the first time that asexual reproduction can be successful in the long term. The animal they studied is the beetle mite Oppiella nova. Until now, the survival of an animal species over a geologically long period of time without sexual reproduction was considered very unlikely, if not impossible.
Some engineers find inspiration in the mechanics of bird flight and the architecture of bee nests. Others think much smaller.
The continents, a specific feature of our planet, still hold many secrets. Using chemical data on sedimentary rocks compiled from the scientific literature from the 1980s to the present day, CNRS researcher Marion Garçon has uncovered a new geological history of the continents. She shows that their growth was not a continuous process, and that they have always been rich in silica. This new study,...
A new study from the Kalahari Desert finds that teamwork allows birds to cope with brutally unpredictable environments.
Intricate natural formations like star-shaped sand dunes or arc-shaped rocks can appear so purposeful in form that it's easy to wonder whether someone has designed them. Scientists have long recognized that a particular combination of random and chaotic energy fields can, over a long period of time, give rise to these kinds of unique formations that dot our globe. Few, however, have succeeded in...
A new analysis suggests that online searches could help correct people's predisposed belief in misinformation, but that searching may still promote negative feelings about a targeted minority group, despite correction of specific information about the group. Tetsuro Kobayashi of City University of Hong Kong and colleagues present these findings in the open-access journal PLOS ONE on September 22,...
The necklace, nametag, earrings or uniform you chose to put on this morning might say more than you realize about your social status, job or some other aspect of your identity.
Using oxygen stable isotope analysis of tooth enamel from animals butchered by humans at the site of Bacho Kiro Cave, Bulgaria, Max Planck researchers show that human groups belonging to an early wave of dispersal of our species into Europe were faced with very cold climatic conditions while they occupied the cave between about 46,000 and 43,000 years ago. Archaeological remains at Bacho Kiro Cave...
On Sept. 18, NASA's InSight lander celebrated its 1,000th Martian day, or sol, by measuring one of the biggest, longest-lasting marsquakes the mission has ever detected. The temblor is estimated to be about a magnitude 4.2 and shook for nearly an hour-and-a-half.
For hundreds of years, Carthage—the Phoenician city-state in North Africa—flourished, establishing itself as a robust trade empire with widespread colonies. As the Carthaginian and Roman empires expanded their reach across Mediterranean Europe and North Africa, escalating tensions over political dominance and trade culminated in the Three Punic Wars.
The answer to climate change—or at least part of it—is blowing in the wind, according to research published Aug. 28 in the journal Climate.
A team led by researchers at Baylor College of Medicine has discovered a mechanism by which transcription factor KLF4 can help to organize chromatin, thus influencing gene expression.
A research team that includes two UO physicists have outlined new techniques for controlling the building blocks of quantum computing, a potentially significant step toward making such computers more accurate and useful.
Harlan and Chad Robins started Seattle-based Adaptive Biotechnologies 12 years ago to find a cure for cancer. Now, they have broadened their mission to take on COVID-19.
The World Health Organization strengthened its air quality guidelines on Wednesday, saying air pollution was now one of the biggest environmental threats to human health, causing seven million premature deaths a year.
Ecosystems on Earth's land surface support multiple functions and services that are critical for society, like biomass production, vegetation's efficiency of using sunlight and water, water retention and climate regulation, and ultimately food security. Climate and environmental changes, as well as anthropogenic impacts, are continuously threatening the provision of these functions. To understand...
Researchers at Kanazawa University report in Science Advances a new method for distinguishing between enantiomers, molecules that are mirror images of each other. The procedure, relevant for the pharmaceutical industry, involves the chemical reaction of target enantiomers with color indicator compounds consisting of one-handed helical polymers, leading to solutions showing different colors in...
