In a few years, powerful new telescopes will usher in a search for habitable worlds outside our solar system. And TRAPPIST-1—a dim, tepid star just a smidge larger than Jupiter—is one of the first places we’ll look. It’s only forty light years away, and it’s home to several promising, Earth-sized exoplanets.

Three siblings, described today in the journal Nature, are the first exoplanets ever discovered around an “ultracool dwarf” star. And they’re a jackpot when it comes to the search for alien life. Each planet is similar in size to Earth or Venus and probably rocky. The planets all skirt the edge of the so-called habitable zone. Finally, these potential Earth twins are so close to us that we can begin studying their atmospheres right now.

“This is basically a paradigm shift,” study co-author Julien de Wit told Gizmodo. “If these planets have atmospheres, they really are the best places to look for life.”

Neurons created from chemically induced neural stem cells. The cells were created from skin cells that were reprogrammed into neural stem cells using a cocktail of only nine chemicals. This is the first time cellular reprogramming has been accomplished without adding external genes to the cells. (credit: Mingliang Zhang, PhD, Gladstone Institutes)

Scientists at the Gladstone Institutes have used chemicals to transform skin cells into heart cells and brain cells, instead of adding external genes — making this accomplishment a breakthrough, according to the scientists.

The research lays the groundwork for one day being able to regenerate lost or damaged cells directly with pharmaceutical drugs — a more efficient and reliable method to reprogram cells and one that avoids medical concerns surrounding genetic engineering.

is the story of the people who intend to build it.

SKY LINE is not just a story about trying to build the largest thing ever, it’s a story about our impulse to push limits and chase dreams, even when the results might not be seen until long after we’re gone. What drives a person to devote his life to pursuits that may take generations to achieve?

Interesting insight on Aluminum Nitride used to create Qubits.

http:///articles/could-aluminum-nitride-be-engineered-to-pro…nteresting insight.


Newswise — Quantum computers have the potential to break common cryptography techniques, search huge datasets and simulate quantum systems in a fraction of the time it would take today’s computers. But before this can happen, engineers need to be able to harness the properties of quantum bits or qubits.

Currently, one of the leading methods for creating qubits in materials involves exploiting the structural atomic defects in diamond. But several researchers at the University of Chicago and Argonne National Laboratory believe that if an analogue defect could be engineered into a less expensive material, the cost of manufacturing quantum technologies could be significantly reduced. Using supercomputers at the National Energy Research Scientific Computing Center (NERSC), which is located at the Lawrence Berkeley National Laboratory (Berkeley Lab), these researchers have identified a possible candidate in aluminum nitride. Their findings were published in Nature Scientific Reports.
