Microscale hydrogel fibers could enable imaging inside tiny tissue structures

Researchers have developed light-transmitting hydrogel fibers that are just hundreds of micrometers in diameter. With further development, these soft fibers could one day make it possible to use imaging techniques to detect early breast cancer hidden inside very small breast duct

After parenthood, same-sex parents diverge from different-sex norms—and from each other, r

Research by Penn sociologist Pilar Gonalons-Pons and others has shown that after a man and a woman have a child, the couple's relative share of paid and unpaid labor tends to change dramatically, with the father specializing in paid work and the mother in child care.

Earth may have been seeding Venus with life for billions of years

A new study suggests Earth may have been sending tiny hitchhikers to Venus for billions of years. Researchers found that asteroid impacts could launch microbes into space, where some might survive the journey and end up suspended in Venus' clouds. If future missions detect life t

Fossil fuel price surges can lead to worse air quality, study finds

Researchers find increases in toxic chemical in the air in some areas as people switch to cheaper wood burningNew research shows that the unreliability of fossil fuel supply chains and consequential price surges can lead to deterioration in air quality as people change their cons

Scientists find evidence of vast hidden magma systems inside Mars

Researchers from the University of Oxford have uncovered evidence that Mars once hosted enormous, Earth-like magmatic systems deep beneath its surface—despite the planet lacking the plate tectonics long thought necessary for this kind of geological complexity.

Researchers discover why fructose doesn't satisfy hunger like glucose

A new study found that fructose and glucose may look the same on a nutrition label, but the brain treats them very differently. In mice, glucose strongly reduced activity in hunger-promoting brain cells, while fructose had a much weaker effect. High-fructose corn syrup triggered

Secrets of how we see color revealed at the molecular level

A global team has cracked a decades-old mystery, revealing the atomic structures of the molecules in our eyes that allow us to see colors. "To understand how we detect light and perceive colors, we need to know the exact structure of light-sensitive molecules in our eyes," said T

Screen reveals new proteins that control RNA processing

Researchers at the University of California San Diego have developed a large-scale screening approach that identifies proteins controlling a fundamental step in gene expression known as alternative polyadenylation (APA). APA determines where an RNA molecule is cut and finished be

Pacific plate's rotation gave Alaska's Aleutian Islands a later-life lift

New research by Brown University geologists confirms that the Aleutian Islands, the archipelago stretching from Alaska to Russia's Kamchatka Peninsula, experienced a massive geological uplift between 5 million and 7 million years ago. The researchers conclude that the uplift—a ri

Evidence identifies ancient Aboriginal mining in the Riverland

Flinders University researchers, in partnership with the River Murray and Mallee Aboriginal Corporation, have found evidence that points to 7,000 years of Aboriginal mining of stone at Sugarloaf Hill in South Australia's Riverland. The dating formed part of the first detailed inv

Apple rootstock response varies to threshold water management during 6 weeks of progressin

As drought and water uncertainty put increasing pressure on orchard systems, researchers at the USDA Agricultural Research Service's Appalachian Fruit Research Station in Kearneysville, West Virginia, launched a study in response to strong grower interest in how modern apple root
