In Just Hours, Sea Scallops Suck Up Billions of Microscopic Plastic Bits

Posted on Categories Discover Magazine

Plastic is in just about everything these days, including living, breathing creatures, from sea critters to people. Environmental waste and litter breaks down into tiny, microscopic particles. Those particles can then seep into water supplies and subsequently work their way into just about anything. That includes plastics in the seafood we eat. Now, a new study in the journal Environmental Science and Technology has found that it takes just six hours for billions of nanoplastic particles  ...read more

Lonesome George’s Genome Shows How the Giant Tortoise Lived Past 100

Posted on Categories Discover Magazine

Giant tortoises have exceptionally long lifespans and often live well past 100 years old. Now, a new study unveils genetic clues to the animals’ longevity, including gene changes that may protect giant tortoises from cancer, bolster the immune system and help regulate metabolism. The findings add to how these processes contribute to aging. “We found interesting [genetic] variants potentially affecting six [aging] hallmarks in giant tortoises, opening new lines for aging research,&rd ...read more

K2 and Gaia Team Up to Confirm 104 New Exoplanets

Posted on Categories Discover Magazine

K2 might have run out of fuel a few months ago, but astronomers are still using its data to uncover a slew of new worlds. Using stats from ESA’s Gaia mission and K2, an extension of NASA’s Kepler Space Telescope, two recent studies have confirmed the existence of 104 new exoplanets. Their characteristics stretch far and wide, including multi-planet systems, terrestrial compositions and planets that orbit dangerously close to their host stars. These newfound bodies can be used to und ...read more

CRISPR Babies Raise an Uncomfortable Reality — Ethical Guidelines Don’t Guarantee Ethical Research

Posted on Categories Discover Magazine

Uncertainty continues to swirl around scientist He Jiankui’s gene editing experiment in China. Using CRISPR technology, He modified a gene related to immune function in human embryos and transferred the embryos to their mother’s womb, producing twin girls. Many questions about the ethical acceptability of the experiment have focused on ethical oversight and informed consent. These are important issues; compliance with established standards of practice is crucial for public trust in ...read more

OSIRIS-REx is About to Meet an Asteroid

Posted on Categories Discover Magazine

NASA’s OSIRIS-REx spacecraft, the space agency’s first craft to bring samples from an asteroid back to Earth, is set to rendezvous with its target, Bennu, at around noon EST today. A special webcast is scheduled for just before the spacecraft reaches Bennu, at 11:45 a.m. EST. During this webcast, NASA officials and scientists will discuss the mission in depth. OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer) launched in September of ...read more
