Exoplanet apparently disappears in latest Hubble observations Posted: 20 Apr 2020 01:57 PM PDT What scientists thought was a planet beyond our solar system has 'vanished.' Though this happens to sci-fi worlds, scientists seek a more plausible explanation. One interpretation: instead of a planet, it could be a dust cloud produced by two large bodies colliding.

ALMA reveals unusual composition of interstellar comet 2I/Borisov Posted: 20 Apr 2020 09:49 AM PDT A galactic visitor entered our solar system last year -- interstellar comet 2I/Borisov. When astronomers pointed the Atacama Large Millimeter/submillimeter Array (ALMA) toward the comet on Dec. 15-16, 2019, for the first time they directly observed the chemicals stored inside an object from a planetary system other than our own.

Rare South American ground beetles sport unusual, likely multi-purpose antennal cleaners Posted: 20 Apr 2020 05:42 AM PDT After 157 years since the description of the South American genus of strange-combed beetles, Nototylus, a second specimen finally has been discovered. The beetle comes to address some over a century-old debates, including whether or not strange-combed beetles possess a feature distinct for ground beetles, why that might be, and whether or not they are indeed ground beetles at all.

Electronics that mimic the human brain in efficient learning Posted: 20 Apr 2020 05:42 AM PDT Only 10 years ago, scientists working on what they hoped would open a new frontier of neuromorphic computing could only dream of a device using miniature tools called memristors that would function/operate like real brain synapses. But now a team has discovered, while on their way to better understanding protein nanowires, how to use these biological, electricity conducting filaments to make a neuromorphic memristor, or 'memory transistor,' device.

Milky Way could be catapulting stars into its outer halo Posted: 19 Apr 2020 08:41 PM PDT Astronomers have shown that clusters of supernovas can cause the birth of scattered, eccentrically orbiting suns in outer stellar halos, upending commonly held notions of how star systems have formed and evolved over billions of years.
