SciShow created a well-produced video on why whales don’t get cancer. The video shows how researchers have discovered extra cancer-fighting genes in elephants and whales and plan to apply these lessons to fighting cancer in humans.

Researchers say there is not an upper limit to human lifespan. However, a new report from the CDC suggests that both sides of the debate may be missing the point.
Summary: Several researchers say there is not an upper limit to human lifespan, contradicting studies which point to a maximum human lifespan. However, a new report from the CDC suggests that both sides of the debate may be missing the point. [This article first appeared on LongevityFacts. Author: Brady Hartman. ]
While many studies have set an upper limit on human lifespan at around 115 to 120 years, other researchers argue that there is no upper limit. This article presents both sides of the debate over the existence of a maximum human lifespan.
Upper Limit to Human Lifespan

Building on prior research that examined the use of an arthritis medication to treat vitiligo, a team of Yale dermatologists has successfully applied a novel combination therapy — the medication and light — to restore skin color in patients.
Tickling the brain with low-intensity electrical stimulation in a specific area can improve verbal short-term memory. Mayo Clinic researchers report their findings in Brain.
The researchers found word recall was enhanced with stimulation of the brain’s lateral temporal cortex, the regions on the sides of the head by the temples and ears. Patients recalled more words from a previously viewed list when low-amplitude electrical stimulation was delivered to the brain. One patient reported that it was easier to picture the words in his mind for remembering.
“The most exciting finding of this research is that our memory for language information can be improved by directly stimulating this underexplored brain area,” says Michal Kucewicz, Ph.D., a Mayo Clinic researcher in the Department of Neurology and co-first author. Dr. Kucewicz compares the stimulation to “tickling” the brain.
Warning over wider global health impacts after findings reveal hundreds of tonnes of colistin – the ‘antibiotic of last resort’ – are being shipped to India’s farms.

I suspect this will be the hands for ATLAS. being field tested by human volunteers to see what it needs to do for average use. And, then blow that away within a few years.
Johnny Matheny is the first person to live with an advanced mind-controlled robotic arm. Last December, researchers from Johns Hopkins Applied Physics Lab delivered the arm to Matheny at his home in Port Richey, Florida. Aside from the occasional demo, this is the first time the Modular Prosthetic Limb (MPL) has spent significant time out of the lab.
Johns Hopkins has received more than $120 million from the US Defense Department to help pay for the arm’s development over the past 10 years.
PETER SINGER, AN expert on future warfare at the New America think-tank, is in no doubt. “What we have is a series of technologies that change the game. They’re not science fiction. They raise new questions. What’s possible? What’s proper?” Mr Singer is talking about artificial intelligence, machine learning, robotics and big-data analytics. Together they will produce systems and weapons with varying degrees of autonomy, from being able to work under human supervision to “thinking” for themselves. The most decisive factor on the battlefield of the future may be the quality of each side’s algorithms. Combat may speed up so much that humans can no longer keep up.
Frank Hoffman, a fellow of the National Defence University who coined the term “hybrid warfare”, believes that these new technologies have the potential not just to change the character of war but even possibly its supposedly immutable nature as a contest of wills. For the first time, the human factors that have defined success in war, “will, fear, decision-making and even the human spark of genius, may be less evident,” he says.
Weapons with a limited degree of autonomy are not new. In 1943 Germany produced a torpedo with an acoustic homing device that helped it find its way to its target. Tomahawk cruise missiles, once fired, can adjust their course using a digital map of Earth’s contours. Anti-missile systems are pre-programmed to decide when to fire and engage an incoming target because the human brain cannot react fast enough.
