Study reveals secrets of planet formation

Science
Oct. 13 (UPI) -- Scientists have discovered a new explanation for how young stars and their newborn planets avoid "radial drift," a phenomenon that can rob stellar systems of their planet-forming material.Most planets form as material coalesces in a star's circumstellar disk of dust and debris. But debris disks can also diffuse or be eaten up by their host star, and researchers have struggled to figure out why this doesn't happen more often.Gas in a circumstellar disk should exert a drag force on debris, pulling the dust inward where it is consumed by the host star. The process, called radial drift, can deplete the material a young stellar system needs to form and grow planets.But new images of the debris disk surrounding the star V1247 Orionis has offered scientists insights into how youn...
Study reveals importance of hydrogen atoms for star formation

Study reveals importance of hydrogen atoms for star formation

Science
Oct. 10 (UPI) -- Until recently, astronomers assumed hydrogen molecules fueled star formation in young galaxies. But new research suggests atomic hydrogen may be equally important to star formation.In the local universe, most hydrogen found inside galaxies exists as individual atoms. Scientists assumed younger galaxies would host less atomic hydrogen and more molecular hydrogen. But cosmic surveys suggest even the earliest galaxies were rich in atomic hydrogen.Now, new analysis by researchers at the University of Western Australia and the International Center for Radio Astronomy Research confirms even galaxies featuring intense rates of star formation host large amounts of atomic hydrogen.Previous studies of "cosmic noon" galaxies have revealed massive reservoirs of molecular hydrogen. Cos...

New test reveals antibiotic-resistant bacteria in 30 minutes

New test reveals antibiotic-resistant bacteria in 30 minutes

Health
Oct. 4 (UPI) -- Researchers at the California Institute of Technology developed a new test that can identify antibiotic-resistant bacteria in as little as 30 minutes.Overuse and misuse are causing antibiotics to lose their effectiveness while, at the same time, many types of bacteria have evolved resistance to commonly used antibiotics. Multi-drug resistant bacteria or superbugs have emerged leading to concerns and warning from the healthcare community."Right now, we're overprescribing, so we're seeing resistance much sooner than we have to for a lot of the antibiotics that we would otherwise want to preserve for more serious situations," Nathan Schoepp, a Caltech graduate student, said in a press release.Current tests for antibiotic resistance take two to three days because a sample has t...
Nest reveals alarm system and smart doorbell

Nest reveals alarm system and smart doorbell

Technology
Nest is expanding its range of smart home products, ending a lull in which it improved existing kit, but did not expand into fresh categories.The items include an internet-connected intruder alarm, a video-streaming doorbell and a door lock system developed in collaboration with Yale.In addition, the firm - which is part of the Google empire - announced an outdoor version of its IQ facial recognition camera.The tech is priced at a premium.The Nest Secure alarm starter pack, for example, will cost $ 499 (£367) when it goes on sale in November.And if owners want to add a cellular back-up service to ensure it still works if the wi-fi connection goes down, there is an additional $ 50 per year charge.By contrast, the Era Vault smartphone alarm system starts at about £150, Yale's SR-320 smart al
