Quantum mechanics is difficult to understand at the best of times, but new evidence suggests that the current standard view of how particles behave on the quantum scale could be very, very wrong.

In fact, the experiment hints that an alternative view predicted almost a century ago might have been right this whole time. And before you get too bummed about that, the good news is that, if confirmed, it would actually make quantum mechanics a whole lot simpler to understand.

So let’s step back for a second here and break this down. First thing’s first, this is just one study, and A LOT more replication and verification would be needed before the standard view comes crumbling down. So don’t go burning any text books just yet, okay? Good.

Fifty-five years ago, Yuri Gagarin rocketed into orbit and began to break our bonds to our planet. To mark the occasion, the nonprofit Breakthrough Institute just announced plans to free us from an even more formidable set of bonds and send a fleet of small spacecraft beyond our solar system, off to the stars. News of the ‘Breakthrough Starshot’ plan was met with great enthusiasm, but also with more than a little skepticism. The distance between stars is vast. Our closest neighbour, the Alpha Centauri system, is 4.4 light years away – roughly 25 trillion miles. The Voyager 1 spacecraft, the fastest object ever created by humans, would take 70,000 years to travel that far. Many reporters greeted the Breakthrough Starshot as an idea grounded more in fantasy than in reality.

The reaction was understandable. All previous plans for interstellar flight relied on non-existent or impractical technologies such as antimatter, wormholes and warp drives. But now we have a concrete path forward, which I have published in detail. It is possible to begin the journey to the stars today.

Drawing on recent advances in photonics and electronics, we could use arrays of lasers to accelerate miniature probes (the size and mass of a semiconductor wafer, weighing less than one ounce) to unprecedented velocities. Particles of light, or photons, have no rest mass but they carry energy and momentum. Just as a sailboat can be propelled by the wind, light sails can ride the momentum of photons by reflecting a wind of intense laser light. We call such focused beams of light ‘directed energy’.

(Medical Xpress)—A large team of researchers from a host of research facilities across Japan has found some genetic variants in some cancer cells that lead to enhanced PD-L1 protein production—which results in increased protection against attacks by the immune system. In their paper published in the journal Nature, the team describes their sequencing study involving adult T-cell leukemia/lymphoma cases, what they found and the possibility that such variants could be used as identifying markers in cancer patients.

Prior studies have shown that an increase in the expression of the protein PD-L1 by cancer cells confers enhanced protection against attacks by the human immune system—PD-1 receptors on T cells bind with PD-L1 causing the immune cells to become unresponsive, preventing them from attacking tumors. In this new effort, the researchers conducted a genetic analysis of a particular type of cancer cell to learn more about the genetic process involved in causing an increase in expression of PD-L1.

The team conducted whole-genome sequencing on samples given by 49 adult patients suffering from leukemia or lymphoma, looking specifically for variations that might account for an increase in expression of PD-L1. In so doing, they found that variations such as duplications, inversions or translocations in 13 of the samples, representing 27 percent of those tested, existed on a certain part of chromosome 9, which prior research had found was the part of the genome responsible for the expression of PD-L1. They report that such alterations seemed to cut off the gene’s 3’ untranslated region of the protein and in some cases led to rearranging the gene’s open reading frame, which allowed more of the protein to be expressed.

“The possibility to selectively activate genes using various engineered variants of the CRISPR-Cas9 system left many researchers questioning which of the available synthetic activating Cas9 proteins to use for their purposes. The main challenge was that all had been uniquely designed and tested in different settings; there was no side-by-side comparison of their relative potentials,” said George Church, Ph.D., who is Core Faculty Member at the Wyss Institute for Biologically Inspired Engineering at Harvard University, leader of its Synthetic Biology Platform, and Professor of Genetics at Harvard Medical School. “We wanted to provide that side-by-side comparison to the biomedical research community.”

In a study published on 23 May in Nature Methods, the Wyss Institute team reports how it rigorously compared and ranked the most commonly used artificial Cas9 activators in different cell types from organisms including humans, mice and flies. The findings provide a valuable guide to researchers, allowing them to streamline their endeavors.

The team also included Wyss Core Faculty Member James Collins, Ph.D., who also is the Termeer Professor of Medical Engineering & Science and Professor of Biological Engineering at the Massachusetts Institute of Technology (MIT)’s Department of Biological Engineering and Norbert Perrimon, Ph.D., a Professor of Genetics at Harvard Medical School.

Oct4, a gene, thought to be inactive in adults, may actually play a vital role in preventing heart attacks and strokes and could also delay some of the effects of ageing, scientists have found. They said the gene could also prove critical in the field of regenerative medicine.

Establishing the trend. Q-dot technology will be in all displays soon.

“Samsung Electronics will skip commercializing OLED for TVs and ho straight to QLED technology, perhaps as soon as 2009. Its strategy is to continue to develop its quantum-dot TVs, which are its current major products, and prepare to commercialize QLED technologies during this time.”

Father of VR worried.

One might think that Jaron Lanier would be elated right now.

More than 30 years after his pioneering work in virtual reality, VR finally appears to be on the verge of becoming a mass market phenomenon. Major companies are investing in the technology; high-profile products are hitting store shelves; and developers of all sorts are creating VR experiences.
