Amazon says it will be ‘even more seamless for customers’.

Amazon is shutting down its standalone Prime Now delivery app, with its speedy two-hour delivery options moving exclusively into the company’s main app and website, the company announced today. Prime Now services have already moved into the main app in India, Japan, and Singapore, while in other countries Amazon is already directing Prime Now users into its main app and website via a pop-up, CNBC notes. The standalone Prime Now app and website will be retired by the end of the year.

Originally launched in 2014, Prime Now was designed to offer deliveries of essential items within hours rather than days for Prime members. The service was initially available in just a small number of cities, but has since expanded to over 5000 locations around the world, CNBC notes. Writing in a blog post, Amazon’s vice president of grocery Stephenie Landry said shutting down the separate app will “make this experience even more seamless for customers.”

On a good day, things exit through the anus. But in rodents and pigs in respiratory distress, oxygen can be absorbed by tissues in the rectum, helping the animals recover, a new study suggests. The scientists behind the research propose that flushing oxygen into the rectum could one day help save human lives if conventional ventilation methods are unavailable.

“It looks like a crazy idea,” says Sean Colgan, a gastroenterologist at the University of Colorado, Boulder, who was not involved in the study. “But if you look at the data, it’s actually a very compelling story.”

Most mammals breathe through their mouths and noses and send oxygen to their body via the lungs. A few aquatic animals, including sea cucumbers and catfish, breathe through their intestines, and the intestinal tissues of humans can readily absorb pharmaceuticals. But no one knew whether oxygen could enter the bloodstream via mammalian intestines.

People can understand these “iconic vocalizations” regardless of their spoken language.

“Iconic vocalizations” may have been the missing link that allowed the first human languages to develop, a new study suggests.

Adam Savage, one of the creators and hosts of the beloved show Mythbusters, collaborated with his friend Richard Browning, founder of Gravity, to demonstrate a flying, bulletproof Iron Man suit that was 3D printed from Titanium. This is a feat that has to be seen to be believed.

The creation of the suit will be featured on a new show that Savage is doing with the Science Channel. It all started when Savage visited the Colorado School of Mines and one of the engineers told him they had Titanium 3D printers, adding “if you want to print something weird, let us know.” To which Savage replied, “Really? How about a full suit of Iron Man armor?”
