Today, NASA awarded a new round of contracts to supply the International Space Station with food, water, and scientific research from late 2019 through 2024.

The space agency both expanded the number of companies providing services from two to three, and more than doubled the potential value of awards to as much as $14 billion over about five years. “This is the next chapter,” said Ellen Ochoa, director of Johnson Space Center, which manages the Space Station program.

Both Orbital ATK, with its Cygnus vehicle, and SpaceX, with its Dragon, won new contracts. Sierra Nevada Corporation joined them with its Dream Chaser. Unlike the other two capsules, the Dream Chaser is a winged vehicle that resembles the space shuttle and lands on a runway. Each of the companies is guaranteed to fly at least six supply missions to the station.

Standing desks—most often installed in efforts to improve physical activity and health—may help get your noggin in shape, too, according to a pilot study published in the International Journal of Environmental Research and Public Health.

Following 27 high school freshman over one school year, researchers found that using a standing desk generally improved the kids’ neurocognitive test scores by seven to 14 percent. The tests, given both at the beginning and end of the school year, evaluated cognitive processes such as reasoning and working memory.

“These findings provide the first preliminary evidence on the neurocognitive benefits of standing desks, which to date have focused largely on energy expenditure,” the authors conclude. If the results are backed up in further studies, it could mean that a simple furniture swap to standing desks could lead to a rise in outstanding students.

Netflix is aiming to block unblocking services like this one. (credit: TVUnblock)

Netflix says it will step up enforcement against subscribers who use VPNs, proxies, and unblocking services to mask their locations. This will help Netflix prevent customers from watching video that isn't licensed for viewing in their country, but it may also affect people who use location-spoofing services for security or privacy reasons.

"Some members use proxies or 'unblockers' to access titles available outside their territory," Content Delivery Architecture VP David Fullagar wrote in a post today. "To address this, we employ the same or similar measures other firms do. This technology continues to evolve and we are evolving with it. That means in coming weeks, those using proxies and unblockers will only be able to access the service in the country where they currently are. We are confident this change won’t impact members not using proxies."

Luckily, Netflix is now available almost worldwide. But not every show is available everywhere.

NEW YORK—Today, the American Museum of Natural History dropped the curtain to reveal one of the biggest paleontological finds of recent years. Everything in that sentence is literal—the museum lowered a curtain to reveal a full-sized cast of the Titanosaur, a species that may be the largest dinosaur ever discovered.

The find itself made news when images came out of paleontologist Diego Pol lying on the femur of the skeleton, which is roughly the size of a sofa (though far less comfortable). Since then, the team from the Museo Paleontologico Egidio Feruglio (MPEF) have excavated over 200 bones, representing 70 percent of the skeleton. Four of those bones (each over a meter long) are also on display at the exhibit. The skeleton on display is made of lightweight fiberglass casts, as the actual bones would weigh far too much to support—the femur alone is roughly 500kg. It's the first outside of the MPEF.

The partnership between MPE and the AMNH was a natural one, as Pol got his PhD there. And he was back on hand for the Titanosaur's unveiling.
