Canaries lava peninsula doubles in size as wind change raises risk

Lava from the erupting volcano on La Palma in Spain's Canary Islands that began cascading into the ocean two days ago has already covered an area bigger than 25 football pitches, with concerns rising over worsening air quality in nearby residential areas, experts said on Thursday.

Salt stress alters legume responses to symbiotic rhizobacteria by modulating gene expression

Crop legumes are an integral part of sustainable agriculture, as several of these species represent an important protein source for both human and animal populations. Legumes engage in a unique and beneficial interaction with a group of soil bacteria, collectively called rhizobia. Rhizobium-legume symbioses lead to the development of new plant organs on the roots called nodules, which host rhizobia. Competent rhizobia within these nodules use a process called nitrogen fixation to convert atmospheric nitrogen, which cannot be used by the plant, into ammonium, which can be used as a nitrogen source. This is a highly valuable process as nitrogen is limited in agricultural systems.

Using dunes to interpret wind on Mars

Dunes develop when wind-blown sand organizes into patterns, most often in deserts and arid or semi-arid parts of the world. Every continent on Earth has dune fields, but dunes and dune-like sand patterns are also found across the solar system: On Mars, Venus, Titan, Comet 67P, and Pluto. On Earth, weather stations measure the wind speed and direction, allowing us to predict and understand airflow in the atmosphere.

Study: Just 1 of 5 people with disabilities works from home; millions still do not have the option

Working from home could revolutionize job opportunities for people with mobility impairments, chronic medical conditions, and other disabilities, but a towering obstacle still stands in the way more than 18 months into the pandemic. A report by the Rutgers Program for Disability Research finds a disproportionate number of people with disabilities work in places like factories, restaurants, and retail stores, where remote work is typically not an option.

Linker histones tune the length and shape of chromosomes

Human life hinges on the ability of our cells to cram six feet of DNA into a 10-micron nucleus—equivalent to fitting a mile of string inside one green pea. But stuffing genes into cramped quarters is only half the battle. The DNA must also remain organized, carefully coiled into loops that ensure the information remains readily accessible and not a tangled mess.

A microscopic worm may shed light on how we perceive gravity

While humans rely on gravity for balance and orientation, the mechanisms by which we actually sense this fundamental force are largely unknown. Odder still, the model organism C. elegans, a microscopic worm, can also sense the direction of gravity, even though there is no known ecological reason for it to do so.

Coral microbiome is key to surviving climate change, new study finds

The microbiomes of corals—which comprise bacteria, fungi and viruses—play an important role in the ability of corals to tolerate rising ocean temperatures, according to new research led by Penn State. The team also identified several genes within certain corals and the symbiotic photosynthetic algae that live inside their tissues that may play a role in their response to heat stress. The findings could inform current coral reef conservation efforts, for example, by highlighting the potential benefits of amending coral reefs with microbes found to bolster corals' heat-stress responses.

At the end of the 1970s, infanticide became a flashpoint in animal behavioral science. Sociobiologist Sarah Hrdy, then a Harvard Ph.D. student, shared her observation in her published thesis that whenever a new langur male entered an established colony, infants would either begin to disappear or show evidence of wounds. Hrdy concluded this was done to eliminate the progeny of rivals and free up now infant-less females for mating. The work provoked an uproar.

Bird poop reveals that when birds migrate, their gut bacteria change

The trillions of bacteria living in our guts play a crucial role in our ability to digest food and fight off disease. All other animals also have communities of bacteria living inside them, that scientists call microbiomes, and learning about them can help scientists put together a more complete picture of how those animals interact with the world. In a new study in the journal Molecular Ecology, researchers used tiny radio trackers to follow the movements of birds that migrated between The Bahamas and Michigan, and they found that the same individual birds' gut bacteria were different in the two locations. And to figure that out, the scientists had to get up close and personal with a lot of bird poop.
