These Scientists Are 3D-Printing New Body Parts for Athletes
Posted by Quinn Sena in categories: 3D printing, bioengineering, biotech/medical
A team of bioengineers has successfully 3D-printed tissues they believe doctors could one day implant into patients to help heal the knee, ankle, and elbow injuries that have ended the careers of countless athletes.
“I think this will be a powerful tool to help people with common sports injuries,” Rice University researcher Sean Bittner said in a press release — though the impact of the group’s work could extend far beyond the turf or pitch.

Neutron star material is ten billion times stronger than steel
Posted by Quinn Sena in categories: cosmology, physics
Neutron stars are born after supernovas, an implosion that compresses an object the size of the sun to about the size of Montreal, making them “a hundred trillion times denser than anything on earth.” Their immense gravity makes their outer layers freeze solid, making them similar to earth with a thin crust enveloping a liquid core.
This will help provide better understand gravitational waves like those detected last year when two neutron stars collided. The new results even suggest that lone neutron stars might generate small gravitational waves.

10(Z)-hexadecenoic acid, a fatty acid found in the soil based bacterium Mycobacterium vaccae, interacts with immune cells to inhibit pathways that drive inflammation and increases resilience to stress. Researchers say the findings could bring us one step closer to developing a microbe-based “stress vaccine”.

Hydrogen-power electric flying vehicle: Long road to liftoff
Posted by Genevieve Klien in categories: drones, energy
LOS ANGELES (AP) — A transportation company is betting its sleek new hydrogen-powered electric flying vehicles will someday serve as taxis, cargo carriers and ambulances of the sky, but experts say they will have to clear a number of regulatory hurdles before being approved for takeoff years in the future.
With six rotors on the roof and seats inside for five people, a passenger model of the Skai (pronounced “sky”) unveiled Wednesday near Los Angeles resembles an oversized drone crossed with a luxury SUV.
Like a drone, the vehicle from Alaka’i Technologies takes off and lands vertically. It’s one of many similar electric flying crafts in production, including prototypes from Boeing and Airbus that made successful test flights this year, according to Vertical Flight Society, an industry group.

How Iron Man’s Stark Arc Reactor Would Work in Real Life
Posted by Quinn Sena in category: physics
Could Tony Stark’s arc reactor exist in real life? Probably not, but Gizmodo’s Ryan Carlyle made a valiant attempt to explain an almost realistic version of the science behind it. As a disclaimer, he warns, “Now, I’m mixing real science and fake science here. So physics nerds and comic-book nerds: Deal with it.”

Scientists discover why a promising cancer drug failed in clinical trials – and how to fix it
Posted by Genevieve Klien in category: biotech/medical
As promising as some treatments are in lab tests, unfortunately they don’t always meet hopes when translated to the real world. Now, scientists at Whitehead Institute for Biomedical Research have investigated a class of cancer drugs that failed in human trials, and found out why. Better yet, they went on to identify another drug that could finally make the treatment work.
