Microplastics are tiny, nearly indestructible fragments shed from everyday plastic products. As we learn more about microplastics, the news keeps getting worse. Already well-documented in our oceans and soil, we’re now discovering them in the unlikeliest of places: our arteries, lungs and even placentas.
Microplastics can take anywhere from 100 to 1,000 years to break down and, in the meantime, our planet and bodies are becoming more polluted with these materials every day.
Finding viable alternatives to traditional petroleum-based plastics and microplastics has never been more important. New research from scientists at the University of California San Diego and materials-science company Algenesis shows that their plant-based polymers biodegrade — even at the microplastic level — in under seven months. The paper, whose authors are all UC San Diego professors, alumni or former research scientists, appears in Nature Scientific Reports.

Frank Borman, an Air Force test pilot, astronaut, and accomplished businessman who led the first crew to fly to the Moon in 1968, died Tuesday in Montana, NASA said Thursday. He was 95 years old.
Borman, joined by crewmates Jim Lovell and Bill Anders, orbited the Moon 10 times over the course of about 20 hours. They were the first people to see the Earth from another world, a memory of "wonderment" Borman recalled decades later. Apollo 8 produced one of the most famous photos ever taken, the iconic "Earthrise" showing a blue orb—the setting for all of human history until then—suspended in the blackness of space over the charcoal gray of the Moon's cratered surface.
Borman was born in Gary, Indiana, on March 14, 1928, and raised in Tucson, Arizona. He learned to fly airplanes as a teenager, then attended the US Military Academy at West Point before earning his commission in the Air Force to start training as a fighter pilot. Following a similar career path as other early astronauts, Borman became an experimental test pilot, receiving a master's degree in aeronautical engineering from Caltech, and served a stint as an assistant professor at West Point.

Ancient Egyptians were an archaeologist's dream. They left behind intricate coffins, massive pyramids and gorgeous hieroglyphs, the pictorial writing code cracked in 1799. But there was one persistent hole in ancient Egyptian identity: their chromosomes. A study led by researchers at the Max Planck Institute for the Science of Human History and the University of Tubingen in Germany managed to plug some of those genetic gaps. Researchers wrung genetic material from 151 Egyptian mummies. radiocarbon dated between Egypt's New Kingdom (the oldest at 1388 B.C.) to the Roman Period (the youngest at 426 A.D.).

U.S. President-elect Barack Obama's NASA transition team is asking U.S. space agency officials to quantify how much money could be saved by canceling the Ares 1 rocket and scaling back the Orion Crew Exploration Vehicle next year.
Obama pledged during his campaign to inject an additional $2 billion into NASA aimed in part at narrowing the gap between the space shuttle's retirement and the introduction of a successor system. While NASA Administrator Mike Griffin and his senior managers are adamant that Ares and Orion are the right vehicles to fill that role, Obama did not endorse either system by name during his campaign.
