Researchers at the Technische Universitaet Muenchen (TUM) Institute for Cognitive Systems are in the process of creating a new robot that features a realistic human face and can reproduce basic dialog, according to a press release sent out by the university on Monday.

According to that media advisory, the so-called "Mask-Bot" features a number of innovations. Those include the projection of a vast array of realistic 3D faces that can be viewed from any number of angles, rather than the "cartoon-like style" utilized by other development teams.

Those faces are displayed on a transparent plastic mask, and can be changed at any time through the use of a projector that is positioned behind the mask itself, the TUM researchers said.

Furthermore, according to Popsci reporter Rebecca Boyle, Mask-Bot utilizes a "talking head animation engine" that allows it to "filter face emotions according to the emotional feel of spoken words, so the faces accurately reflect the speakers' expressions."

A research team from the Functional Genomics Institute has successfully reprogrammed cells from elderly donors in vitro to induced pluripotent stem cells (iPSC) and to rejuvenated human embryonic stem cells (hESC).

Jean-Marc Lemaitre, study leader and Inserm researcher at the Functional Genomics Institute (Inserm, CNRS, and Université de Montpellier 1 and 2), and Inserm's AVENIR Genomic plasticity and aging team, have accomplished the rejuvenation of cells from elderly donors, which could prove to be beneficial for regenerative medicine.

Since 2007, research teams have been able to reprogram human adult cells into iPSCs, which have similar traits as hESCs. HESCs are the desired result because they are undifferentiated cells that can form various types of differentiated adult cells in the body. Using embryonic stem cells is out of the question due to ethical problems with using stem cells from a human embryo, so researchers have been using different avenues to achieve the same results.

Tractor beams -- the ability to trap and move objects using laser light -- are the stuff of science fiction, but a team of NASA scientists has won funding to study the concept for remotely capturing planetary or atmospheric particles and delivering them to a robotic rover or orbiting spacecraft for analysis.

The NASA Office of the Chief Technologist (OCT) has awarded Principal Investigator Paul Stysley and team members Demetrios Poulios and Barry Coyle at NASA's Goddard Space Flight Center in Greenbelt, Md., $100,000 to study three experimental methods for corralling particles and transporting them via laser light to an instrument -- akin to a vacuum using suction to collect and transport dirt to a canister or bag. Once delivered, an instrument would then characterize their composition.

"Though a mainstay in science fiction, and Star Trek in particular, laser-based trapping isn't fanciful or beyond current technological know-how," Stysley said. The team has identified three different approaches for transporting particles, as well as single molecules, viruses, ribonucleic acid, and fully functioning cells, using the power of light.

Deflecting Killer Asteroids Away From Earth: How We Could Do It

A huge asteroid's close approach to Earth tomorrow (Nov. 8) reinforces that we live in a cosmic shooting gallery, and we can't just sit around waiting to get hit again, experts say.

Asteroid 2005 YU55, which is the size of an aircraft carrier, will zip within the moon's orbit tomorrow, but it poses no danger of hitting us for the foreseeable future. Eventually, however, one of its big space rock cousins will barrel straight toward Earth, as asteroids have done millions of times throughout our planet's history.

If we want to avoid going the way of the dinosaurs, which were wiped out by an asteroid strike 65 million years ago, we're going to have to deflect a killer space rock someday, researchers say. Fortunately, we know how to do it.

"We have the capability - physically, technically - to protect the Earth from asteroid impacts," said former astronaut Rusty Schweickart, chairman of the B612 Foundation, a group dedicated to predicting and preventing catastrophic asteroid strikes. "We are now able to very slightly and subtly reshape the solar system in order to enhance human survival."

In fact, we have several different techniques at our disposal to nudge killer asteroids away from Earth. Here's a brief rundown of the possible arrows in our planetary defense quiver.

Boeing Co and All Nippon Airways are investigating a landing gear problem on the 787 Dreamliner, the first technical glitch reported since the new jetliner entered service less than two weeks ago, the airline said on Monday.

Pilots on the first of two aircraft delivered so far to ANA were forced on Sunday to deploy the landing gear using a manual backup system, after an indicator lamp suggested the wheels were not properly down.

They landed at Okayama on the second attempt following the incident, the airline said.

"We are not yet sure what the problem was, but we are investigating," an airline spokesman said, adding that Boeing was also involved in the investigation.

SOTT Focus: Cosmic Turkey Shoot

Today we are going to look at the Summary of Conclusions about Fireballs and Meteorites that Victor Clube attached to his cover letter to the Chief, Physics and BMD Coordinator of the European Office of Aerospace Research and Development back in 1996, 5 years before September 11, 2001; that, and a few other things.

I often get accused of "fear mongering" because I keep bringing this subject up again and again. I even think that it is fascinating that the big breakthrough in my experiment in Superluminal Communication came on the day that the fragments of Comet Shoemaker-Levy began striking Jupiter - even at the very moment of the first impact - and that this communication with "myself in the future" has focused so much attention on the subject of swarms of comets and comet fragments that repeatedly barrel through the solar system, wreaking havoc and bringing death and destruction to earth. As a result of the research prompted by this communication, I wrote an entire 800 page book that is woven around the issue of cometary explosion type catastrophes that obviously have occurred repeatedly throughout history: The Secret History of The World.

In the early days of publishing the results of this experiment, I was nonplussed by the many attacks I came under from all quarters. I was accused of "channeling aliens" (not true); of wanting to "start a cult" (what is cultic about doing research into scientific subjects and exposing religion for the fraud it is?) and so on. That sort of thing really hurt and puzzled me at first, but I have now seen it for the blessing it was: it has helped me to learn about the kinds of people who are in charge of our world, the kind of people who want to keep secrets so that they can hang onto power: the kind of people who create such things as "The War on Terror" to conceal from the masses of humanity the future that may very well bring our civilization to an end; the kind of people who know that survival of cometary bombardment is possible and who want to be the only ones who do survive, and to hell with everyone else.

Is the electromagnetic constant a constant?

Star study suggests life-friendly conditions could be regional

Could yet another universal constant, the value assigned to the electromagnetic force, be less constant than we thought? And could variability of the constant help explain life in the universe?

That's the tantalizing hypothesis offered by Australian astronomers, who believe that the value alpha, referring to the strength of the electromagnetic force (and measured at 1/137.03599976), may not be constant everywhere.

A team of scientists has used the NASA/ESA Hubble Space Telescope to observe a quasar accretion disc - a brightly glowing disc of matter that is slowly being sucked into its galaxy's central black hole. Their study makes use of a novel technique that uses gravitational lensing to give an immense boost to the power of the telescope. The incredible precision of the method has allowed astronomers to directly measure the disc's size and plot the temperature across different parts of the disc.

The Mystery Of A Murmuration


Brandon Keim conveys the physics behind starling formations, which were featured a recent Mental Health Break:
Mathematical analysis of flock dynamics show how each starling's movement is influenced by every other starling, and vice versa. It doesn't matter how large a flock is, or if two birds are on opposite sides. It's as if every individual is connected to the same network. That phenomenon is known as scale-free correlation, and transcends biology. The closest fit to equations describing starling flock patterns come from the literature of "criticality," of crystal formation and avalanches - systems poised on the brink, capable of near-instantaneous transformation.

How Earth's Axis Affects Your Sleep Habits

At 2 a.m. on Sunday (Nov. 6), most of the United States will enjoy the upside to the annual daylight saving time shift - setting our clocks back by an hour.

But be careful how you enjoy it, cautions Dr. Anita Valanju Shelgikar, director of the sleep medicine fellowship program at the University of Michigan.

"It's truly easier to go this way than in the other direction," Shelgikar said, referring to the spring-time shift forward an hour. "It does give you an extra hour in the morning to sleep, but it can throw people off, primarily because people say I can stay up a lot later because I have an extra hour in the morning to sleep and ultimately, they sleep deprive themselves."

The arrival of winter presents a more difficult transition than the shift back, since, as the days shorten, a gap widens between our internal body clocks and the natural day, she said. This becomes more of an issue farther north, since days become even shorter.
