Evolutionary biologist Andrew Gallup explains why we yawn after others

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.

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.

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.

In a gripping underwater rescue, Spanish divers freed a 12-metre long humpback whale that became entangled in an illegal drift net off the Balearic island of...

Researchers at Iowa State University found significantly different state tax rates affect where new businesses set up shop near state lines. Their study published in the journal Small Business Economics shows the fourth greatest distortion in the U.S. is between Iowa and its northwest neighbor.

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...

In the face of catastrophic events, scenes of property destruction give the first indications of economic loss for businesses. Interruptions to the companies' ability to produce goods and services, however, actually have a much greater effect on their bottom line.

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.

Researchers recently discovered a helicoidal-shaped defect in layered polymers, uncovering how solvents can diffuse through layers and produce color changes.

Anticipating key features of wind plants a decade or more ahead of their installation can inform today's investment, research, and energy system planning decisions. Researchers elicited opinions from more than 140 of the world's leading experts about their expectations of future wind plant design in 2035.

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.

A new study looking at litter in the UK has revealed the types of materials and products being dumped in its hedgerows and waterways.

Dr. Edwin L. Thomas, professor in the Department of Materials Science and Engineering, and a team of researchers from Texas A&M University and Yonsei University have recently discovered a helicoidal-shaped defect in layered polymers, uncovering how solvents can diffuse through layers and produce color changes.

Mexican experts said Monday that 35% more monarch butterflies arrived this year to spend the winter in mountaintop forests, compared to the previous season.

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.

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.

NASA's Hubble Space Telescope has calibrated more than 40 'milepost markers' of space and time to help scientists precisely measure the expansion rate of the universe -- a quest with a plot twist.

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.

Mexican experts said Monday that 35 per cent more monarch butterflies arrived this year to spend the winter in mountaintop forests, compared to the previous...

Do you like opera and classical music? Would you rather go to pop concerts? Or do you belong with those who are all-consuming when it comes to music, books, movies, and other cultural manifestations?

Developing drugs that affect the function of the Cnpy4 gene, which is involved in human embryo development, may provide potential new treatment options for diseases, including cancer.

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...
