Using thoughts to control airplanes

Posted by Seb in category: thought controlled

Research news — Technische Universität München

Pilots of the future could be able to control their aircraft by merely thinking commands. Scientists of the Technische Universität München and the TU Berlin have now demonstrated the feasibility of flying via brain control – with astonishing accuracy.

The pilot is wearing a white cap with myriad attached cables. His gaze is concentrated on the runway ahead of him. All of a sudden the control stick starts to move, as if by magic. The airplane banks and then approaches straight on towards the runway. The position of the plane is corrected time and again until the landing gear gently touches down. During the entire maneuver the pilot touches neither pedals nor controls.

Researchers create flexible wires that could double as batteries

Colin Jeffrey — Gizmag

We literally live in a wired world, with wires snaking hither and yon transmitting electricity and data. Many are visible, while many more are hidden in the walls of buildings, the panels of cars, and the fuselage of aircraft. Now, imagine; what if we were able to turn each and every one of these into a battery that not only transmitted electricity but stored it too? Well, two researchers from the University of Central Florida (UCF) imagined that too, and came up with a way to use nano-technology to make wires with supercapacitance that may eventually also double as batteries.

Professor Jayan Thomas and his Ph.D. student Zenan Yu premised their design on their ability to grow “nanowhiskers” of copper oxide in a laboratory that would provide the conductive link between between the inner and outer layers of their supercapacitor wire.

Mice With MS-Like Condition Walk Again After Human Stem Cell Treatment

Posted by Seb in categories: biotech/medical, health

University of Utah

Mice severely disabled by a condition similar to multiple sclerosis (MS) could walk less than two weeks following treatment with human stem cells. The finding, which uncovers new avenues for treating MS, will be published online on May 15, 2014, in the journal Stem Cell Reports.

When scientists transplanted human stem cells into MS mice, they expected no benefit from the treatment. They thought the cells would be rejected, much like rejection of an organ transplant.

Instead, the experiment yielded spectacular results.

Researchers use light to coax stem cells to regenerate teeth

Posted by Seb in category: biotech/medical

Kristen Kusek — Wyss Institute

A Harvard-led team is the first to demonstrate the ability to use low-power light to trigger stem cells inside the body to regenerate tissue, an advance they reported in Science Translational Medicine. The research, led by David J. Mooney, Robert P. Pinkas Family Professor of Bioengineering at the Harvard School of Engineering and Applied Sciences (SEAS), lays the foundation for a host of clinical applications in restorative dentistry and regenerative medicine more broadly, such as wound healing, bone regeneration, and more.

The team used a low-power laser to trigger human dental stem cells to form dentin, the hard tissue that is similar to bone and makes up the bulk of teeth. What’s more, they outlined the precise molecular mechanism involved, and demonstrated its prowess using multiple laboratory and animal models.

Astronomy Gravitational waves turn to dust after claims of flawed analysis

Posted by Seb in category: astronomy

Ian Sample — The Guardian

It was hailed as one of the most important scientific discoveries of the century, the birth of a new era in physics and a shoo-in for a Nobel prize.

The claim from Harvard University that it had discovered gravitational waves – and thereby evidence for the theory of cosmic inflation and the existence of a multiverse – caused a worldwide sensation in March. But the celebrations are now looking decidedly premature.

Mind uploading won’t lead to immortality

Uploading the content of one’s mind, including one’s personality, memories and emotions, into a computer may one day be possible, but it won’t transfer our biological consciousness and won’t make us immortal.

Uploading one’s mind into a computer, a concept popularized by the 2014 movie Transcendence starring Johnny Depp, is likely to become at least partially possible, but won’t lead to immortality. Major objections have been raised regarding the feasibility of mind uploading. Even if we could surpass every technical obstacle and successfully copy the totality of one’s mind, emotions, memories, personality and intellect into a machine, that would be just that: a copy, which itself can be copied again and again on various computers.

THE DILEMMA OF SPLIT CONSCIOUSNESS

Neuroscientists have not yet been able to explain what consciousness is, or how it works at a neurological level. Once they do, it is might be possible to reproduce consciousness in artificial intelligence. If that proves feasible, then it should in theory be possible to replicate our consciousness on computers too. Or is that jumpig to conclusions ?
