Why are male mice afraid of bananas?

Researchers from McGill University have identified a form of chemical signaling in mice to defend their offspring. The researchers found that proximity to pregnant and lactating female mice increased stress hormones in males and even decreased their sensitivity to pain.

Polymersomes efficiently deliver siRNA to treat breast cancers in preclinical model

Small interfering RNAs—or siRNAs—hold promise to treat tumors, through their ability to specifically knock down oncogenes that promote tumor growth without the toxicity that accompanies chemotherapy. However, the siRNAs need a delivery vehicle to protect them from degradation and clearance on their journey through the bloodstream to the cancer tumor.

Highest Efficiency 1-Sun Solar Cell

Researchers have created a solar cell with a record 39.5% efficiency under 1-sun global illumination. This is believed to be the highest efficiency solar cell of any type, measured using standard 1-sun conditions.

A candlelight-like glow from a flexible organic LED

Giving off a comfortable glow, candles set the ambiance for a special dinner or just a quiet evening at home. However, some lighting alternatives, such as electronic candles, give off unwanted blue wavelengths that interfere with the body's circadian rhythm. Now, researchers reporting in ACS Applied Electronic Materials have fabricated an improved bendable organic LED that releases...

New gene identified in arrhythmogenic cardiomyopathy

Researchers have used advanced sequencing technology to better understand the heart disease arrhythmogenic cardiomyopathy, in which heart muscle tissue is replaced by fat cells. Using explanted human hearts, they found regions in which heart muscle was actively degenerated and identified a new gene, ZBTB11, that drives heart muscle cell degradation.

Going virtual hurts student career prospects

As in-person scientific meetings and gathering have been replaced by virtual meetings during the pandemic, students and young professionals are seeing career fairs and networking events transition into remote experiences that simply lack the same impact as getting together.

How cities in the West have water amid drought

As drought and climate change tighten their grip on the American West, the sight of fountains, swimming pools, gardens and golf courses in cities like Phoenix, Las Vegas, Los Angeles, Salt Lake City, Boise, and Albuquerque can be jarring at first glance.

Study shows that scavengers, such as raccoons, can be picky eaters

When you picture a finicky eater, a raccoon doesn't usually come to mind. But new research from the University of Georgia has revealed that scavengers, such as raccoons and vultures, can be selective about what they eat. The study provides insight into how nutrients can cycle through food webs.

AI reveals unsuspected math underlying search for exoplanets

Artificial intelligence (AI) algorithms trained on real astronomical observations now outperform astronomers in sifting through massive amounts of data to find new exploding stars, identify new types of galaxies and detect the mergers of massive stars, accelerating the rate of new discovery in the world's oldest science.

AI reveals unsuspected math underlying search for exoplanets

The astronomers' goal: find an artificial intelligence algorithm to interpret microlensing events captured by the upcoming Roman Space Telescope and speed detection of exoplanets around other stars. They achieved that, but the AI told them something unexpected and deep: the theory used to infer stellar and exoplanetary masses and orbits from observations was incomplete. Digging into the...
