A team of researchers from the National Institute of Informatics (NII) in Tokyo and NTT Basic Research Laboratories (BRL, Nippon Telegraph and Telephone Corporation) in Japan have published an explanation of how quantum systems may be able to heat up by cooling down. Their paper appeared recently in Physical Review Letters.

“Heating by cooling sounds rather counterintuitive, but if the system has symmetries, decay could mean many things,” says Kae Nemoto, a professor in the Principles of Informatics Research Division at NII which is part of the Inter-University Research Institute Corporation Research Organization of Information and Systems (ROIS).

Nemoto and her team examined a double sub–domain system coupled to a single constant temperature reservoir. Each sub-domain contained multiple spins—a form of angular momentum carried by elementary particles such as electrons and nuclei. The researchers considered the situation in which the spins within each sub-domain are aligned with respect to each other, but the sub-domains themselves are oppositely aligned (for instance all up in one and all down in the second). This creates a certain symmetry in the system.

What is Holochain? #notblockchain

Holochain has been in the works since before the Bitcoin whitepaper and now it is being released on the world. There is no mining, no cryptocurrency and it claims to be more efficient than Blockchain. Could Holochain be the future or decentralization?

KILAUEA VOLCANO, BIG ISLAND (HawaiiNewsNow) — Scientists with the U.S.G.S. issued a Volcano Activity Notice on Tuesday, warning that the magma system beneath Kilauea’s East Rift Zone had become increasingly pressurized and that a new vent could form ‘at any time’ if conditions persist.

Based on data observed over the past month, the new vent could form on either the existing Pu’u O’o cone or on an adjacent area along the East Rift Zone, scientists say.

Magma is currently accumulating ‘at shallow depths’ beneath the existing Pu’u O’o eruption. The last time a major vent opened in the area was June 27, 2014 – the appropriately-named June 27th Flow sent lava flowing more than 12 miles into the town of Pahoa, causing minor damage to roads and structures.

A man in Paris has become the world’s first to successfully receive two facial transplants.

Jérôme Hamon, 43, underwent his first face transplantation procedure in 2010 to treat neurofibromatosis, a genetic disorder characterized by the growth of tumors along nerves in the skin, brain and other parts of the body. Yet Hamon’s body rejected the original transplant.

In January, a team of surgeons and paramedics at Georges Pompidou European Hospital AP-HP, led by surgeon Dr. Laurent Lantieri, performed Hamon’s second transplant.

If it’s started to feel like all summer blockbuster movies are being written by robots [INSERT FORMER PRO WRESTLER, INSERT GIANT CGI ANIMAL], you’ll be disquieted to learn that that future may not be too far off.

The meditation app Calm teamed up with the tech team at Botnik to write a new Brothers Grimm-style fairy tale entirely through artificial intelligence. By inputting the data from existing Brothers Grimm stories and using predictive text technology (and with a few human writers stitching things together), the group at Botnik crafted “The Princess and the Fox,” a story about “a talking fox [who] helps the lowly miller’s son to rescue the beautiful princess from the fate of having to marry a dreadful prince who she does not love.”

“We’re doing for the Brothers Grimm what Jurassic Park did for dinosaurs,” says Michael Acton Smith, co-founder of Calm, in a press press release. “We’re bringing them back from the dead, with modern science.” (It perhaps bears remembering here that Jurassic Park famously did not end well.)

But the mice didn’t seem any smarter than usual.

Will robots dream in ones and zeros? Can they appreciate a rose by any other name? Perhaps a new class calculus will provide us with those answers, and machines with consciousness.

Human stem cells—the biological jack of all trades—have revolutionized modern medicine, with their ability to transform into specialized cell types.

But the current approach, which requires specialized instructive protein molecules known as growth factors, comes with risks, including the potential development of unwanted tissue, i.e., a tumor.

Researchers at Texas A&M University, however, have discovered a gentler approach.
