Surveillance pathway tells cells when they run low on lipids

Posted: 18 May 2022 12:23 PM PDT

Researchers have discovered a molecular pathway that allows cells to sense when their lipid supplies become depleted, prompting a flurry of activity that prevents starvation. The findings might someday lead to new ways to combat metabolic disorders and a variety of other health conditions.

How plants colonize the base of an active stratovolcano

New research in plants that colonized the base of an active stratovolcano reveals that two simple molecular steps rewired nutrient transport, enabling adaptation.

Keeping buildings cooler with a wood-based foam

Posted: 18 May 2022 11:07 AM PDT

Summertime is almost here, a time when many people try to beat the heat. But running air conditioners constantly can be expensive and wasteful. Now, researchers have designed a lightweight foam made from wood-based cellulose nanocrystals that reflects sunlight, emits absorbed heat and is thermally insulating. They suggest that the material could reduce buildings' cooling energy needs by more than a third.

For wetland plants, sea-level rise stamps out benefits of higher CO2

Posted: 18 May 2022 11:07 AM PDT

Wetlands across the globe are in danger of drowning from rising seas. But for decades, scientists held out hope that another aspect of climate change -- rising carbon dioxide (CO2) -- could trigger extra plant growth, enabling coastal wetlands to grow fast enough to outpace sea-level rise. That helpful side effect is disappearing, scientists have discovered.

Both nature and nurture contribute to signatures of socioeconomic status in the brain

Researchers found that a person's genetics and the environment in which they live contribute to how socioeconomic status shapes the architecture of the brain.

At-risk sea life in the Atlantic needs better protection from an increase in shipping

Posted: 18 May 2022 07:18 AM PDT

New research has shown a dramatic increase in shipping in the North East Atlantic.  Scientists now warn that more monitoring in the area is required to help protect sea life on the at-risk register.

Researchers discover effective combination immunotherapy for liver cancer

Researchers have discovered a specific combination immunotherapy that shows promise in the fight against liver cancer.

Conservationists find high DDT and PCB contamination risk for critically endangered California coastal condors

Posted: 18 May 2022 05:04 AM PDT

A new study has found contaminants, banned decades ago, are still imperiling critically endangered California condors. The condors may be at increased risk for reproductive impairment because they consume dead marine mammals along the California coast.

High rates of landscape degradation not product of landscape fires

Posted: 18 May 2022 05:03 AM PDT

Once humans discovered how to tame fire, they began using it for heat, cooking, to scare away animals and to alter their environs, especially burning areas to plant and to restore grazing land. In Madagascar, scientists and conservationists have long believed that fire is a leading cause of high landscape degradation, but an international team of researchers have found that medium to large fires on the island are similar to those on other tropical locations.

Astronauts may one day drink water from ancient moon volcanoes

Posted: 17 May 2022 06:04 PM PDT

If any humans had been alive 2 to 4 billion years ago, they may have looked up and seen a sliver of frost on the moon's surface. Some of that ice may still be hiding in craters on the lunar surface today.

Friendly fungi announce themselves to their hosts

Commensal fungi need to be alive and actively making proteins that stimulate our immune cells to elicit that commensal benefit, according to new findings.

Density, benign disease raise risk of breast cancer
