A new battery technology, based on a metal-mesh membrane and electrodes made of molten sodium and nickel chloride, could open the way for more intermittent, renewable power sources on the grid. It could make wind and solar capable of delivering reliable baseload electricity...

“Imagine if someone were to fine-tune our system so that you could get 85 percent of the carbon and nitrogen back from waste into protein without having to use hydroponics or artificial light,” said House. “That would be a fantastic development for deep-space travel.” Image: Space Toilet © iStock Photo ALJ1

A Penn State team has shown that it is possible to rapidly break down solid and liquid waste to grow food with a series of microbial reactors, while simultaneously minimizing pathogen growth. “We envisioned and tested the concept of simultaneously treating astronauts’ waste with microbes while producing a biomass that is edible either directly or indirectly depending on safety concerns,” said Christopher House, professor of geosciences, Penn State...

The nuclei of most galaxies host supermassive black holes containing millions to billions of solar-masses of material. The immediate environments of these black holes typically include a tori of dust and gas and, as material falls toward the black hole, the gas radiates copiously at all wavelengths...

Researchers have developed a universal vaccine to combat influenza A viruses that produces long-lasting immunity in mice and protects them against the limitations of seasonal flu vaccines, according to a study led by Georgia State University. The CDC estimates influenza has resulted in between 12,000 and 56,000 deaths annually in the U.S. since 2010.

Seasonal flu vaccines must be updated each year to match the influenza viruses that are predicted to be most common during the upcoming flu season, but protection doesn’t always meet expectations or new viruses emerge and manufacturers incorrectly guess which viruses will end up spreading...
