![]() Such a mind-boggling effect is due to the brain-bending qualities of the two stars. The death dance of a white dwarf star and a pulsar reveal relativistic frame dragging - also known as the Lense-Thirring effect - in which a fast-spinning object distorts the fabric of space-time around it. Reference: Science paper Stellar dance swirls the fabric of space-time Whereas humans have a fantastically diverse gut zoo, all honey bees have the same six to eight gut microbes, so the procedure could be widely applicable. The RNA targets the bee-killing Varroa destructor mite, and the deadly ‘deformed wing’ virus the mite transmits, causing the mite and virus to dismantle some of their own genes. ![]() Researchers genetically modified Snodgrassella alvi, a bacterium that lives happily in the bees’ gut, to produce a specific type of RNA. The honey bees microbiome has been weaponized to fight off the bees’ enemies. ![]() Wired | 6 min read Engineered symbionts could save bees “Saying goodbye to Spitzer is saying goodbye to a dear friend that journeyed with us through the cosmos,” says astrophysicist Nikole Lewis. There was no technical barrier to its mission continuing, but NASA chose to redirect resources to the imminent (but much-delayed) James Webb Space Telescope. ![]() The spacecraft was placed in safe mode, ceasing all science operations. Yesterday NASA bid farewell to the Spitzer Space Telescope as its transformative 16-year-old mission came to an end. NASA/JPL-Caltech & NASA/JPL-Caltech/STScI NASA says goodnight to Spitzer Telescope Spitzer images of nebulae in the constellation Cepheus, clouds of dust and gas surrounding the bright star Eta Carinae, newborn stars in the Orion nebula and the bow shock caused by the stellar winds of Zeta Ophiuchi.
