Laughing Gas in Space could mean Life
Exoplanet hunters should check for N2O

Scientists at UC Riverside are suggesting something is missing from the typical roster of chemicals that astrobiologists use to search for life on planets around other stars — laughing gas.

Chemical compounds in a planet’s atmosphere that could indicate life, called biosignatures, typically include gases found in abundance in Earth’s atmosphere today.

“There’s been a lot of thought put into oxygen and methane as biosignatures. Fewer researchers have seriously considered nitrous oxide, but we think that may be a mistake,” said Eddie Schwieterman, an astrobiologist in UCR’s Department of Earth and Planetary Sciences.

This conclusion, and the modeling work that led to it,...

Combining Time-Restricted Eating and HIIT Improves Health Measures in Women with Obesity

Both time-restricted eating (TRE) and high-intensity interval training (HIIT) have been shown to improve cardiometabolic health in people who are overweight and at risk of serious disease. Now a randomized, controlled trial has tested whether combining these two approaches is more effective than either of them on their own. The results, publishing in the journal Cell Metabolism on October 4, show that the combination improved the average long-term glycemic control compared to a no-intervention control group and induced 2-fold greater reductions in fat mass and visceral fat area compared with each intervention in isolation.

“Isolated TRE and HIIT have received increasing attention for being effective and feasible strategies for at-risk populations,” says senior author Trine Moholdt,...

Collision may have Formed the Moon in Mere Hours, Simulations Reveal

A new NASA and Durham University simulation puts forth a different theory of the Moon’s origin – the Moon may have formed in a matter of hours, when material from the Earth and a Mars sized-body were launched directly into orbit after the impact. The simulations used in this research are some of the most detailed of their kind, operating at the highest resolution of any simulation run to study the Moon’s origins or other giant impacts.

Most theories claim the Moon formed out of the debris of this collision, coalescing in orbit overa months or years. A new simulation puts forth a different theory — the Moon may have formed immediately, in a matter of hours, when material from the Earth and Theia was launched directly into orbit after the impact.

Solar Harvesting System has Potential to Generate Solar Power 24/7

The sun
A new way to harvest solar energy breaks the efficiency record of all existing technologies and clears the way to use solar power 24/7.

A professor is reporting on a new type of solar energy harvesting that breaks the efficiency record of all existing technologies. And no less important, it clears the way to use solar power 24/7. Thomas Edison once said, “So long as the sun shines, man will be able to develop power in abundance.”

They’ve done an amazing job with photovoltaic cells which convert sunlight directly into energy. And still, with all the research, history and science behind it, there are limits to how much solar power can be harvested and used — as its generation is restricted only to the daytime.

A University of Houston professor is continuing the historic quest, repo...
