Scientists successfully grow human brain equivalent to 5-week-old foetus in the lab

Growing brain tissue in a dish has been done before, but bold new research announced this week shows that scientists’ ability to create human brains in laboratory settings has come a long way quickly.

Researchers at the Ohio State University in the US claim to have developed the most complete laboratory-grown human brain ever, creating a model with the brain maturity of a 5-week-old foetus. The brain, which is approximately the size of a pencil eraser, contains 99 percent of the genes that would be present in a natural human foetal brain.

“It not only looks like the developing brain, its diverse cell types express nearly all genes like a brain,” Rene Anand, professor of biological chemistry and pharmacology at Ohio State and lead researcher on the brain model, said in a statement.

First Near-Fully Formed Brain Grown In Lab, Ohio State Scientists Say

Scientists at Ohio State University say they’ve grown the first near-complete human brain in a lab.

The brain organoid, if licensed for commercial lab use, could help speed research for neurological diseases and disorders, like Alzheimer’s and autism, Rene Anand, an Ohio State professor who worked on the project, said in a statement Tuesday.

“We will have a more precise prediction of efficacy of therapy and possible side effects before we do clinical trials,” Anand told The Huffington Post via email, explaining how his model is a more ethical alternative to trials that use rodent specimens. Anand said reducing the use of animals improves research as they’re “not as likely to predict clinical outcomes as human brain models.”

Watch Boston Dynamics’ Robot Run Outside Oh God They’re Coming For Us

Possible cause of the singularity Boston Dynamics is secretive about upcoming projects, but new footage shows their robots in action—and the results are highly unsettling.

First you can see Spot, an agile autonomous quadruped ripped directly from Isaac Asimov’s nightmares, opening a door with the arm it sports instead of a face. Spot would almost be adorable the way it trots around on four legs except for the protruding face-arm that will turn the handle on your front door with its superstrength. Sleep well tonight.

Future of Virtual Reality Series Launches Today

If you’ve ever watched someone experience virtual reality for the first time, you know it can involve screaming, flapping arms, and occasional falls.

On one level people know their bodies are safe on the stable chair, but as their minds are catapulted through outer space on a spaceship to Mars or beamed into a refugee camp in Syria —they can’t help but lose their grip on reality and go along for the ride.

In fact, our brains don’t even require photorealism for suspension of disbelief in VR. A choppy CGI rendition will cause our heart rates to increase and our palms to get sweaty when we’re riding a virtual roller coaster or standing on the edge of a virtual building looking at the ground 30 stories below.

First 3D-Printed Drug Ushers in Era of Downloadable Medicine — Singularity HUB

Last week, the FDA approved the first 3D-printed prescription drug, essentially validating the technology as a new heavyweight player in big pharma. “This may be the first truly mass manufactured product made by 3D printing,” said Dr. Michael Cima, a professor at MIT who helped invent the pill-printing technology back in 1997, in an email to Singularity Hub. “It’s revolutionary.”

The printed pill, SPRITAM levetiracetam, is a drug that fights many kinds of epileptic seizures. The brainchild of a little-known Ohio-based company Aprecia, SPRITAM is essentially an old drug ingredient packaged into a brand new, more effective delivery system. Unlike current formulations of the same drug, SPRITAM immediately dissolves upon contact with water and bursts into effect — a property obviously beneficial when trying to curtail sudden-onset seizure episodes.
