Daily exposure to blue light may accelerate aging, even if it doesn't reach your eyes
Prolonged exposure to blue light, such as that which emanates from your phone, computer and household fixtures, could be affecting your longevity, even if it's not shining in your eyes. New research suggests that the blue wavelengths produced by light-emitting diodes damage cells in the brain as well as retinas, according to a new study in a model organism.
Scientists find early humans moved through Mediterranean earlier than believed
Scientists have unearthed new evidence in Greece proving that the island of Naxos was inhabited by Neanderthals and earlier humans at least 200,000 years ago, tens of thousands of years earlier than previously believed.
Hubble observes first confirmed interstellar comet
Hubble has given astronomers their best look yet at an interstellar visitor -- comet 2I/Borisov -- whose speed and trajectory indicate it has come from beyond our solar system. Comet 2I/Borisov is only the second such interstellar object known to have passed through the solar system.
Gas 'waterfalls' reveal infant planets around young star
For the first time, astronomers have witnessed 3D motions of gas in a planet-forming disk. At three locations in the disk around a young star called HD 163296, gas is flowing like a waterfall into gaps that are most likely caused by planets in formation. These gas flows have long been predicted and would directly influence the chemical composition of planet atmospheres.
How mucus tames microbes
New research reveals that glycans -- branched sugar molecules found in mucus -- can prevent bacteria from communicating with each other and forming infectious biofilms, effectively rendering the microbes harmless.
