A team of microbiologists and virologists at Wuhan University, working with colleagues from the Chinese Academy of Sciences, the University of Washington and Humabs BioMed SA, has found that it is possible to use coronavirus DNA to create receptors t.....»»
Coyotes are thriving despite human and predator pressures, large-scale study finds
Research led by the University of New Hampshire sheds light on how coyotes, North America's most successful predators, are responding to various environmental pressures, including human development, hunting and competition with larger carnivores. Sur.....»»
Grocery stores are more reliable than sushi restaurants in labeling salmon properly, Seattle study finds
In a study of salmon samples from Seattle, Washington, grocery stores and sushi restaurants, DNA analysis revealed that 18% were mislabeled. Tracie Delgado and colleagues at Seattle Pacific University, WA, U.S., present these findings in the open-acc.....»»
Biologists discover how plants evolved multiple ways to override genetic instructions
Biologists at Washington University in St. Louis have discovered the origin of a curious duplication that gives plants multiple ways to override instructions that are coded into their DNA. This research could help scientists exploit a plant's existin.....»»
Mighty radio bursts linked to massive galaxies: New clues about how magnetars form
Since their discovery in 2007, fast radio bursts—extremely energetic pulses of radio-frequency light—have lit up the sky repeatedly, leading astronomers on a chase to uncover their origins. Currently, confirmed fast radio bursts, or FRBs, number.....»»
Genetic repair via CRISPR can inadvertently introduce other defects, researchers show
The CRISPR molecular scissors have the potential to revolutionize the treatment of genetic diseases. This is because they can be used to correct specific defective sections of the genome. Unfortunately, however, there is a catch: under certain condit.....»»
Asteroid grains shed light on the outer solar system"s origins
Tiny grains from a distant asteroid are revealing clues to the magnetic forces that shaped the far reaches of the solar system more than 4.6 billion years ago......»»
Testing thousands of RNA enzymes helps find first "twister ribozyme" in mammals
The "RNA world" hypothesis proposes that the earliest life on Earth may have been based on RNA—a single-stranded molecule similar in many ways to DNA—like some modern viruses. This is because, like DNA, RNA can carry genetic information, but, lik.....»»
Scientists shed light on an arms race between barley and a fungal pathogen
Scientists from the Leibniz Institute of Plant Biochemistry (IPB), together with partners from the University of Cologne, have discovered a new group of defense substances in barley that are effective against a broad spectrum of fungal pathogens. One.....»»
Survey highlights "publish or perish" culture as key factor in research irreproducibility
An international survey involving over 1,600 biomedical researchers has shed light on the perceived causes of irreproducibility in research results. The survey, which included participants from various countries and research institutions, aimed to id.....»»
Pimax Crystal Light review: a new standard for affordable PC VR

A single atom can change the directional profile of the light emitted in scanning tunneling microscopes
Researchers from Madrid explain a phenomenon that allows the direction of light emission to be controlled at the atomic scale. The paper provides a detailed explanation of how the profile of the light collected in a scanning tunneling microscope (STM.....»»
Scientists discover all-optical nuclear magnetic resonance analog with quantum fluids of light
Researchers from Skoltech, the University of Warsaw, and the University of Iceland have demonstrated that by optical means it is possible to excite and stir an exciton-polariton condensate, which emits a linearly polarized light with a polarization a.....»»
Tracing the journey from Egyptian cat mummies to modern house pets
