A 39-year-old man who had been completely paralyzed for four years was able to voluntarily control his leg muscles and take thousands of steps in a “robotic exoskeleton” device during five days of training, and for two weeks afterward, UCLA scientists report.

This is the first time that a person with chronic, complete paralysis has regained enough voluntary control to actively work with a robotic device designed to enhance mobility.

Advances in 3-D printing have led to new ways to make bone and some other relatively simple body parts that can be implanted in patients. But finding an ideal bio-ink has stalled progress toward printing more complex tissues with versatile functions. Now scientists have developed a silk-based ink that could open up new possibilities toward that goal.

Martian dust storms rank among the most impressive in our Solar System. But no matter how menacing they appear from Mars orbit, they’re not likely to cause astronauts to abort future surface missions, says a planetary scientist who studies the phenomena.

Although such storms routinely engulf large swaths of the Red Planet for days at a time, any emergency serious enough to evacuate a crew isn’t likely to be triggered by a dust storm of the sort depicted in the forthcoming film adaptation of Andy Weir’s novel The Martian.

A year ahead of the 2016 U.S. presidential election, it’s amazing at how small a role the American space program has played during this tempestuous summer of early primary campaigning.

It’s certain that NASA will live long and prosper no matter who’s ultimately elected as our 45th president; the American space agency has done so for 50-plus years. But even in this burgeoning age of commercial space development, political catchphrases such as “Back to the Moon and on to Mars;” “Capture an asteroid and on to Mars;” or even bypass the Moon and “Go directly to Mars” somehow still ring hollow.

On the morning of the recent booster test launch of NASA’s Space Launch System (SLS), I watched NASA Administrator Charles Bolden enthusiastically describe the new launch system. He noted NASA’s goal of using the new system to capture a large boulder from a near Earth asteroid and bring it back to a stable lunar orbit. This planned Asteroid Redirect Mission (ARM) as it’s now called would happen by the middle of the next decade. Then by the 2030s, NASA would re-purpose SLS for a manned mission to Mars. But such massive undertakings still need political will and the funding that goes with it.

“Derek Klingenberg—a farmer in Kansas, according to Popular Mechanics—pulled a bluegill out of his pond by baiting a fishing line attached to a DJI Phantom 2 quadcopter, Popular Science reported. Klingenberg told Popular Science that he used a fake worm as bait, and it took about 10 minutes of drone fishing to catch the fish.”

New Device Brings ‘Dead’ Hearts Back to Life.

“Heart transplants only come from brain-dead donors whose hearts are cut away while their bodies are still healthy. Without a device such as this, hearts from dead donors are considered by surgeons as too damaged to use. With the device, the heart gets the essential infusion of blood to restore its energy.”
