It doesn’t look good for Florida.

Researchers are finding that kelp, eelgrass, and other vegetation can effectively absorb CO₂ and reduce acidity in the ocean. Growing these plants in local waters, scientists say, could help mitigate the damaging impacts of acidification on marine life.

Astronomers have a new tool to help them find habitable planets in our galaxy: the Habitable Planet Finder (HPF), a high-precision spectrograph. The HPF can be used to detect worlds which have some key qualities, like being a rocky planet orbiting an red dwarf. A red dwarf, also known as an M-dwarf, is a type of star that is relatively cool, small, and dim, and is somewhat similar to our Sun (which is classified as a white or yellow dwarf.) Red dwarfs are common in the Milky Way, like the nearby Barnard’s star, making them good hunting grounds for exoplanets.

“About 70 percent of the stars in our galaxy are M-dwarfs like Barnard’s star, but the near-infrared light they emit has made it difficult for astronomers to see their planets with ordinary optical telescopes,” Paul Robertson, assistant professor of physics and astronomy at the University of California, Irvine, said in a statement. “With the HPF, it’s now open season for exoplanet hunting on a greatly expanded selection of stellar targets.”

The HPF measures subtle changes in the color of light given off by stars, which can indicate the influence of an orbiting planet. In particular, it searches for planets with a low mass located within the “habitable zone” of their stars where surface water can exist. The spectrograph has already demonstrated its usefulness by confirming the existence of a super-Earth which is orbiting Barnard’s star during its commissioning, and should be able to detect many more planets similar in size to Earth in the future.

Biologically inspired circuitry could help build future low-power AI chips—if some obstacles are overcome.

The news: Researchers at the US National Institute of Standards and Technology built a new magnetically controlled electronic synapse, an artificial equivalent of the ones that link neurons. They fire millions of times faster than the ones in your brain, while using 1,000th as much energy (which is also less than any other artificial synapse to date).

Why it matters: Synthetic synapses, which gather multiple signals and fire electronic pulses at a threshold, may be an alternative to transistors in regular processors. They can be assembled to create so-called neuromorphic chips that work more like a brain. Such devices can run artificial neural networks, which underpin modern AI, more efficiently than regular chips. This new synapse could make them even more energy-efficient.

Zombie Bacteria that sounds like a Netflix Series…not really, but a bacteria that devours roundworms has been found. #karma A new species of bacterium Chryseobacterium nematophagum, has been found to digest its hosts—roundworm parasites—from the inside out. The findings, which are presented in the open access journal BMC Biology, suggest that the bacteria may potentially be used in future, to control roundworm infections in animals, plants, and, potentially, humans.
