Genetic mutations from extinct human relatives called the Denisovans might have influenced modern human immune systems, as well as fat and blood sugar levels, researchers say.

Very little is known about the Denisovans. The first evidence of them was discovered in Denisova Cave in Siberia in 2008, and DNA from their fossils suggests they shared an origin with Neanderthals but were nearly as genetically distinct from Neanderthals as Neanderthals were from modern humans.

Previous work found that any modern humans with ancestry outside of Africa inherited about 1.5 to 2.1 percent of their DNA from Neanderthals. In contrast, prior research suggested that substantial levels of Denisovan ancestry are found only in the Pacific islands of Melanesia. Scientists are increasingly uncovering the effects of Neanderthal ancestry on modern humans, from potential immune boosts to increased risks for depression, obesity, heart attacks, nicotine addiction. However, relatively little was known about the effects of Denisovan ancestry.

Two comets, perhaps fragments of the same larger space rock, will make two of the closest passes in modern history, one right after the other.

A chemical compound named Perovskite could be the next big innovation in solar power technology. http://voc.tv/14JQHoo

Imagine a two-dimensional world — you, your friends, everything is 2D. In his 1884 novella, Edwin Abbott invented this world and called it Flatland. Alex Rosenthal and George Zaidan take the premise of Flatland one dimension further, imploring us to consider how we would see dimensions different from our own and why the exploration just may be worth it.

Have you ever wanted to mess with a video by making its cast say things they never would on camera? You might get that chance. Researchers have built a face detection system that lets you impose your facial expressions on people in videos. The software uses an off-the-shelf webcam to create a 3D model of your face in real time, and distorts it to fit the facial details in the target footage. The result, as you’ll see below, is eerily authentic-looking: you can have a dead-serious Vladimir Putin make funny faces, or Donald Trump blab when he’d otherwise stay silent.

This isn’t about to reach software you can buy, but the implications for video creation are big if it becomes more than a university project. You could use the tool to mess with your friends by having celebrities say audacious things, or have famous figures recite dialogue in movies without needing to painstakingly animate faces frame by frame. In other words: get ready for an era when even the most plausible videos aren’t safe from a little computer trickery.

It sounds really obvious, but hospitals aren’t for healthy people. The world’s entire health system is really there to react once people get ill. If doctors are able to catch an illness at stage one that’s great, but if it reaches stage three or four there’s often not that much that can be done. So what if we could treat patients at stage zero and predict the likelihood of contracting diseases? We could then get treatment to people who need it much earlier and take preventative steps to avoid illness altogether.

Currently, when we think of monitoring in healthcare we’re usually referring to monitoring patients’ reactions to drugs or treatments, but this is changing. No amateur runner’s uniform is complete these days without a Fitbit or some kind of analytics tool to monitor progress, so the idea of monitoring the healthy is becoming ingrained in the public’s consciousness. But Fitbits only scrape the surface of what we can do. What if the data from fitness trackers could be combined with medical records, census data and the details of supermarket loyalty cards to predict the likelihood of contracting a particular disease?

With big data we can move from reacting to predicting, but how do we move beyond just making predictions; how do we prevent disease from occurring altogether? Up until now all of our monitoring technology has been located outside of the body, but nano-sized entities made of DNA could one day patrol the body, only acting when they come into contact with specific cells – cancer cells, for example. The technology that would turn tiny machines – roughly the size of a virus – into molecular delivery trucks that transport medication is already being worked on by bioengineers. If this kind of technology can be used to treat cancer, without needing to release toxic agents into the body, can the same technology be inserted into a healthy person and lie in wait for the opportunity to fight disease on its host’s behalf?

When we think of the future of technology, we often imagine gadgets that will make us go faster. But some of the truly exciting developments will be around gadgets that help us with the tricky aspects of our emotional lives.

Awesome. Still, not sure masses would like such a large thing on their head. We’ll see how Occulus does. When it’s as small as any pair of glasses or shades it’ll take off I think.

What if technology could connect us more deeply with our surroundings instead of distracting us from the real world? With the Meta 2, an augmented reality headset that makes it possible for users to see, grab and move holograms just like physical objects, Meron Gribetz hopes to extend our senses through a more natural machine. Join Gribetz as he takes the TED stage to demonstrate the reality-shifting Meta 2 for the first time. (Featuring Q&A with TED Curator Chris Anderson)

Paul March also endorsed the technical information and insights of forum member Rodal on the topic of EMdrive. Rodal indicates the differences in dielectric materials and other nuances of interpreting the known results.

A radio frequency (RF) resonant cavity thruster is a proposed new type of electromagnetic thruster. Unlike conventional electromagnetic thrusters, a resonant cavity thruster would use no reaction mass, and emit no directional radiation.

A few variations on such thrusters have been proposed. Aerospace engineer Roger Shawyer designed the EmDrive in 2001, and has persistently promoted the idea since then through his company, Satellite Propulsion Research.
