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.

Aliens symbolize the best and worst of humanity. When we dream of aliens, we are pondering our future selves.

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?”

As of August 28th, you can now use a 3D printer to produce custom candy gummies in Berlin. The world’s first 3D candy printer, Magic Candy Factory, had been in development for over a year through German company Katjes Fassin’s UK subsidiary, and can print gummies in 3–10 minutes; competing machines take up to an hour.

A variety of molecules protrude from the cell surface, including glycoproteins, glycolipids, and the newly discovered glycoRNAs.

Sugars attach to certain RNA molecules on the outside membrane of the cell. The newly discovered “glycoRNAs” may be involved in immune signaling.

In a surprise find, scientists have discovered sugar-coated RNA molecules decorating the surface of cells.

Automakers are expecting $110 billion in lost sales this year due to shortages.

If ARM doesn’t prove it can be a level playing field in Nvidia’s ownership, customers will defect to alternatives.

Conditions like recurrent miscarriage, preeclampsia, preterm birth and stillbirth are affected by the female’s immune response in ways that the partner’s sperm contribute to.

Sperm are generally viewed as having just one action in reproduction—to fertilize the female’s egg—but studies at the University of Adelaide are overturning that view.

Published in Nature Research journal Communications Biology, new research shows that sperm also deliver signals directly to the female reproductive tissues to increase the chances of conception.
