For the first time, a government is supporting a plan to create animal embryos with human cells and bring them to term, resulting in a type of humanimal known as a human-animal chimera.

According to Nature, a committee from Japan’s science ministry signed off on a request by researchers to grow human pancreases in either rats or mice, the first such experiment to gain approval since a government ban was reversed earlier this year.

ALON — Transparent Aluminum — is a ceramic composed of Aluminium, Oxygen and Nitrogen. Transparent Aluminum, was once pure science fiction, a technical term used in a Star Trek Movie from the 80’s.

In the movie Star Trek 4 The Voyage Home, Captain Kirk and his team, go back in time to acquire 2 whales from the past and transport them back to the future. Scotty needed some materials to make a holding tank for whales on his ship, but had no money to pay for the materials.

Scientists recently found one billion-year-old fungi in Canada, changing the way we view evolution and the timing of plants and animals here on Earth.

The fossilized specimen was collected in Canada’s Arctic by an international team and later identified to be the oldest fungi ever found, sitting somewhere between 900 million and 1 billion years old. The research, published recently in Nature, changes how we view eukaryotes colonizing the land.

The fossilized fungi were analyzed and researchers found the presence of chitin, a unique substance that is found on the cell walls of fungi. The specimen was then age dated using precise measurements of radioactive isotope ratios within the sample.

Researchers in Canada and Sweden have used a novel Crispr system to reverse harm caused by muscular dystrophy – usually thought to be permanent – in mice. Pre-clinical studies often treat animals early, before symptoms can be detected, says Ronald Cohn, senior scientist, president and chief executive officer of The Hospital for Sick Children in Toronto.

‘Our results now show that the therapeutic window may indeed be wider,’ Cohn tells Chemistry World. This is significant as all patients ‘are currently diagnosed at a time when symptoms are already presenting’, he adds. The researchers are now exploring partnerships with industry to work towards bringing the research into a clinical trial.

In October 2017, European officials reported that a cloud of the radioactive isotope ruthenium-106 had mysteriously wafted over the continent. Its likely source was in the southern Ural Mountains, near Mayak, the Russian nuclear facility involved in a deadly nuclear disaster in 1957. Strangely, Russia at first denied — but then acknowledged — there had been a surge of radiation. However, it rejected the idea that the surge was the source of the cloud. Now, scientists report in a new PNAS paper that they’ve narrowed down where it actually came from.

There were a number of hypotheses to explain the source of the cloud, which spread over most of Europe and even reached Florida, Guadeloupe, Kuwait, and Mongolia in tiny amounts. Fortunately, it was deemed non-hazardous.

Russian officials denied that Mayak, one of the country’s largest nuclear facilities, was the source of the ruthenium. In November 2017, Rosatom, the state company that runs Russia’s nuclear industry, pointed to high radiation in Italy, Romania, and Ukraine, suggesting they might have been the source. And in December of that year, Russian officials, reasserting that Mayak was not the source of the cloud, suggested the cloud might have come from a satellite that had burned up in the atmosphere. Other hypotheses arose, but scientists have lacked the evidence to support or reject them until now.

As Tesla is preparing to launch its ‘Tesla Semi’ electric truck next year, some are starting to imagine other possible applications than freight transport, like a Tesla Semi electric motorhome.

Motorhomes are often associated with freedom. The idea that you can take your entire home on the road and explore the world is extremely appealing to many.

Physicists from Nanyang Technological University, Singapore (NTU Singapore) and the Niels Bohr Institute in Copenhagen, Denmark, have devised a method to turn a non-magnetic metal into a magnet using laser light.

Magnets and their magnetic field are typically produced by circulating currents, like those found in everyday electromagnetic coils. The ‘handedness’ of these coils—whether they are wound in clockwise or anticlockwise fashion—determines the direction of the magnetic field produced.

The scientists theorise that when non-magnetic metallic disks are illuminated by linearly polarised light—light that does not possess any handedness of its own—circulating electric currents and hence magnetism can spontaneously emerge in the disk.

A research team lead by Osaka University demonstrated how information encoded in the circular polarization of a laser beam can be translated into the spin state of an electron in a quantum dot, each being a quantum bit and a quantum computer candidate. The achievement represents a major step towards a “quantum internet,” in which future computers can rapidly and securely send and receive quantum information.

Quantum computers have the potential to vastly outperform current systems because they work in a fundamentally different way. Instead of processing discrete ones and zeros, quantum information, whether stored in electron spins or transmitted by laser photons, can be in a superposition of multiple states simultaneously. Moreover, the states of two or more objects can become entangled, so that the status of one cannot be completely described without this other. Handling entangled states allow quantum computers to evaluate many possibilities simultaneously, as well as transmit information from place to place immune from eavesdropping.

However, these entangled states can be very fragile, lasting only microseconds before losing coherence. To realize the goal of a quantum internet, over which coherent light signals can relay quantum information, these signals must be able to interact with electron spins inside distant computers.
