The Leonardo Permanent Multipurpose Module (PMM) has been reopened at its new location on the forward port of the Tranquility module. Commander Terry Virts and Flight Engineer Samantha Cristoforetti worked on completing PMM configuration activities.
Paleontologists Dr William Korth of Rochester Institute of Vertebrate Paleontology and Dr Joshua Samuels of John Day Fossil Beds National Monument have described four new genera and ten new species of prehistoric rodents that lived in what is now Oregon during the Oligocene epoch, between 30 and 22 million years ago. The newly-discovered genera include: [...] —> Read More
This week we are one step closer to understanding a world in our solar system that I believe has the best chance of supporting life beyond our own planet. NASA has just announced details about what instruments a space probe to Jupiter’s moon Europa will carry when it makes multiple flybys in the next decade.
I couldn’t be more excited to be the project scientist of this mission. I first learned of Europa as a kid who made planets out of tennis balls covered in construction paper and masking tape and hung them from my bedroom ceiling on Long Island. In 1979, the twin Voyager 1 and Voyager 2 spacecraft flew past Jupiter and its moons. Though not the largest moon of Jupiter, Europa was the most enigmatic: Voyager’s pictures showed a maze of dark lines marking the bright icy surface, like a cracked eggshell.
Seeing the first Voyager 2 photos of Europa inspired the famous Carl Sagan to wonder whether the dark bands were mountain-like ridges or valley-like troughs. What do they say about the history of this world? I was fortunate to take Sagan’s seminar course at Cornell University in 1985 and was fascinated by the possibility of a watery ocean within Jupiter’s moon Europa. It was uncertain whether such an ocean would have frozen solid over time or could persist today.
To learn more, NASA sent the Galileo spacecraft past Europa a dozen times while orbiting Jupiter between 1996 and 2002. Galileo images showed Europa’s surface to be crisscrossed by both mountain-like ridges and valley-like troughs. The patterns of the ridges and cracks suggest an ocean below that permits the ice shell to flex and break. Giant bulls-eye-like scars tell of large comets that collided with —> Read More

Japanese residents fled the remote southern island of Kuchinoerabu on Friday following the eruption of Mount Shindake — and the spectacular eruption was captured on video.
Mount Shindake spewed black clouds as high as 5.6 miles into the sky as authorities evacuated nearly 140 people from the island, with one man reportedly suffering minor burns but all others believed to be safe. Video captured by the Japan Meteorological Agency and published by the Japanese public broadcaster NHK shows the initial explosion mushrooming into a towering cloud of ash:
“There was a really loud, ‘dong’ sound of an explosion,” Nobuaki Hayashi, a local village chief, told NHK, “and then black smoke rose, darkening the sky … It smells of sulphur.”

“I heard a loud boom and when I looked at the mountains, I saw a gigantic plume rising above,” an innkeeper told the Japan Times. “There was an eruption last year, but this time the sound was really loud … I thought I’d be dead if I got caught in the cloud.”
Experts told NHK they’d seen signs an eruption was likely, including swelling of the ground and volcanic earthquakes.

While the overall rate of colorectal cancer (CRC) is declining, CRC specifically among young patients is increasing. Previous studies have shown that CRC in patients younger than 50 years old tends to be more aggressive than CRC in older patients. A new study offers early evidence of genetic differences between CRC in young and old patients, possibly pointing toward different treatments and strategies in combating the young form of the disease. —> Read More
