Human activity threatens vertebrate evolutionary history

A new study maps for the first time the evolutionary history of the world's terrestrial vertebrates: amphibians, birds, mammals and reptiles. It explores how areas with large concentrations of evolutionarily distinct species are being impacted by our ever-increasing 'human footprint.'

Discovery of ancient super-eruptions indicates the Yellowstone hotspot may be waning

Researchers report two newly identified super-eruptions associated with the Yellowstone hotspot track, including what they believe was the volcanic province's largest and most cataclysmic event. The results indicate the hotspot, which today fuels the famous geysers, mudpots, and fumaroles in Yellowstone National Park, may be waning in intensity.

First optical measurements of Milky Way's Fermi Bubbles probe their origin

Astronomers have for the first time measured the Fermi Bubbles in the visible light spectrum. The Fermi Bubbles are two enormous outflows of high-energy gas that emanate from the Milky Way and the finding refines our understanding of the properties of these mysterious blobs.

'Poisoned arrow' defeats antibiotic-resistant bacteria

Poison is lethal all on its own -- as are arrows -- and together, they can take down the strongest opponents. Researchers have found an antibiotic that simultaneously punctures bacterial walls and destroys folate within their cells -- killing like a poisoned arrow -- while proving immune to antibiotic resistance.

Metasurface opens world of polarization

Researchers have designed a metasurface that can be continuously tuned from linear to elliptical birefringence, opening up the entire space of polarization control with just one device. This single metasurface can operate as many birefringent materials in parallel, enabling more compact polarization manipulation, which could have far-reaching applications in polarization imaging, quantum optics, and other areas.

App determines COVID-19 disease severity using artificial intelligence, biomarkers

A new mobile app can help clinicians determine which patients with the novel coronavirus (COVID-19) are likely to have severe cases. Created by researchers at NYU College of Dentistry, the app uses artificial intelligence (AI) to assess risk factors and key biomarkers from blood tests, producing a COVID-19 'severity score.'

Synthetic red blood cells mimic natural ones, and have new abilities

Scientists have tried to develop synthetic red blood cells that mimic the favorable properties of natural ones, such as flexibility, oxygen transport and long circulation times. But so far, most artificial red blood cells have had one or a few, but not all, key features of the natural versions. Now, researchers have made synthetic red blood cells that have all of the cells' natural abilities, plus a few new ones.

Artificial intelligence can improve how chest images are used in care of COVID-19 patients

Artificial intelligence (AI) should be used to expand the role of chest X-ray imaging -- using computed tomography, or CT -- in diagnosing and assessing coronavirus infection so that it can be more than just a means of screening for signs of COVID-19 in a patient's lungs, say researchers in a new report.
