How the seasons might influence brain size

Research suggests that changes in air pressure can cause changes in brain volume, in humans as well as in animalsA study by New England researchers looks at how weather and season influence brain size, comparing over three thousand MRI scans and finding small but distinct effects. “Basically, on a stormy day or in the winter, the cerebellum is larger than normal, while the rest of the brain is...

Massive damage of rare plants probed at Nevada mine site

State and federal authorities are investigating the mysterious loss of a significant swath of a rare desert wildflower that's being considered for federal protection at a contentious mine site in Nevada with some of the largest untapped lithium deposits in the world.

Aqua satellite helps confirm Subtropical Storm Alpha

Subtropical Storm Alpha has formed near the coast of Portugal, becoming the first named storm using the Greek Alphabet list, now that the annual list of names is exhausted. NASA's Aqua satellite obtained visible imagery of the new storm.

NASA touts lunar landing tech, and Blue Origin says there’ll be a flight test ‘soon’

Apollo 11 commander Neil Armstrong famously had to dodge a boulder-strewn crater just seconds before the first moon landing in 1969 — but for future lunar touchdowns, NASA expects robotic eyes to see such missions to safe landings. And Amazon CEO Jeff Bezos' Blue Origin space venture is helping to make it so. Today NASA talked up a precision landing system known as SPLICE (which stands for...

Sometimes Food Fights Back

Peering through a microscope in 2016, Dania Albini gazed at an algae-eating water flea. Its gut appeared full and green with all the ingested teeny-tiny Chlorella vulgaris algae. But she also observed bright green blobs of this phytoplankton in an unexpected place: the herbivore's brood pouch."I was really surprised to see them there," said Albini, an aquatic ecologist then at...

T cell shortage linked to severe COVID-19 in elderly; antiseptic spray may limit virus spread

A lower supply of a certain type of immune cell in older people that is critical to fighting foreign invaders may help explain their vulnerability to severe COVID-19, scientists say. When germs enter the body, the initial "innate" immune response generates inflammation not specifically targeted at the bacteria or virus. Within days, the more precise "adaptive" immune response starts generating...

Like humans, chimpanzees can suffer for life if orphaned before adulthood

Researchers observed three chimpanzee communities of the Tai National Park. They kept full demographic records and collected fecal samples to conduct paternity tests on all new community members, for up to 30 years. Catherine Crockford, the lead author, says: "When we study our closest living relatives, like chimpanzees, we can learn about the ancient environmental factors that made us human. Our...

Indian monsoon can be predicted better after volcanic eruptions

Large volcanic eruptions can help to forecast monsoons over India. This seasonal rainfall is key for the country's agriculture and thus for feeding 1 billion people. As erratic as they are, volcanic eruptions improve the predictability, an Indian-German research team finds. What seems to be a paradox is, in fact, due to a stronger coupling between the monsoon over large parts of South and...

Connecting the dots on food access

A new study simultaneously examined the preferences of community members and compared those with the community-based programs and resources available to identify the most viable strategies for addressing disparities in healthy food consumption.

Lack of UK airport tests aiding Covid-19 spread, scientists warn

Sage experts say poor quarantine compliance is also bringing virus into countryCoronavirus – latest updatesSee all our coronavirus coverageGovernment scientists have warned of a “developing situation” over people bringing coronavirus into the UK after travelling abroad and returning home without being tested.People who travel overseas are required to quarantine for two weeks on their return...

New design principles for spin-based quantum materials

As our lives become increasingly intertwined with technology—whether supporting communication while working remotely or streaming our favorite show—so too does our reliance on the data these devices create. Data centers supporting these technology ecosystems produce a significant carbon footprint—and consume 200 terawatt hours of energy each year, greater than the annual energy consumption...
