Very cool!

As we age, tiny blood vessels in the brain stiffen and sometimes rupture, causing “microbleeds.” This damage has been associated with neurodegenerative diseases and cognitive decline, but whether the brain can naturally repair itself beyond growing new blood-vessel tissue has been unknown. A zebrafish study published on May 3 in Immunity describes for the first time how white blood cells called macrophages can grab the broken ends of a blood vessel and stick them back together.

“Microbleeding occurs very often in the human brain, particularly in elderly people,” says Lingfei Luo, a developmental geneticist at Southwest University in China. “We believe that this macrophage behavior is the major cellular mechanism to repair ruptures of blood vessels and avoid microbleeding in the brain.”

To simulate a human brain microbleed, Luo and his colleagues shot lasers into the brains of live zebrafish to rupture small blood vessels, creating a clean split in the tissue with two broken ends. Then, the researchers used a specialized microscope to watch what happened next.

AR working ; I cannot wait to see what we do with AR in many of the other enterprise apps.

Augmented reality is transforming field maintenance. With DAQRI Smart Helmet™, workers get real-time visual instructions, equipment diagnostics, and operational data, turning every user into a maintenance expert.

By combining DAQRI’s innovative design with Intel’s powerful technology, DAQRI Smart Helmet helps workers be more productive and less error-prone. As an example of how powerful augmented reality can be, Kazakhstan Seamless Pipe (KSP Steel) used the helmet to achieve a 40% increase in worker productivity and a 50% reduction in factory downtime.

More insights around the logical quantum gate for photons discovered by Max Planck Institute of Quantum Optics (MPQ). Being able to leverage this gate enables Qubits in transmission and processing can be more controlled and manipulated through this discovery, and places us closer to a stable Quantum Computing environment.

MPQ scientists take an important step towards a logical quantum gate for photons.

Scientists from all over the world are working on concepts for future quantum computers and their experimental realization. Commonly, a typical quantum computer is considered to be based on a network of quantum particles that serve for storing, encoding and processing quantum information. In analogy to the case of a classical computer a quantum logic gate that assigns output signals to input signals in a deterministic way would be an essential building block. A team around Dr. Stephan Dürr from the Quantum Dynamics Division of Prof. Gerhard Rempe at the Max Planck Institute of Quantum Optics has now demonstrated in an experiment how an important gate operation — the exchange of the binary bit values 0 and 1 — can be realized with single photons. A first light pulse containing one photon only is stored as an excitation in an ultracold cloud of about 100,000 rubidium atoms.

All I can say is WOW!!!! US Security Intelligence awards contract to University of Sydney who is also partnering with China. Also, this should send a huge message to the university in the US that Sydney is kicking it.

The US office of the director of national intelligence has awarded a mutlimillion dollar research grant to an international consortium that includes a quantum science laboratory at the University of Sydney.

I am totally jealous right now!

Australia opened a new quantum computing lab at the University of New South Wales (UNSW).

This follows the government’s $26-million investment in the Centre of Excellence for Quantum Computation & Communication Technology (CQC2T) as part of the National Innovation and Science Agenda. The government’s investment is supported by $10 million each from Telstra and the Commonwealth Bank of Australia (CBA).

Today’s digital computers have finite processing power whereas a commercial quantum computer will deliver a significant speed-up in power, including over a supercomputer.

Cambridge’s new nano-scale light-powered piston engine that may one day energize devices to treat diseases directly or deliver drugs.

At the University of Cambridge researchers have developed a nano-scale light-powered piston engine that may one day energize devices to treat diseases directly or deliver drugs in powerful new ways. The device consists of charged gold nanoparticles within a polymer that bends and relaxes in response to heat changes. The polymer absorbs water when cooled, expanding in size, while heating the gold nanoparticles using a laser raises the temperature of the polymer, shedding the absorbed water and relaxing in response. This process happens in a fraction of a second, and as long as a laser is made to flip between being on and off, the engine keeps working.

According to the researchers, the force generated given the weight of the device is quite huge, at least a hundred times greater than existing motors or even muscle cells.

“It’s like an explosion,” said Dr Tao Ding from Cambridge’s Cavendish Laboratory, and the paper’s first author, in a press release. “We have hundreds of gold balls flying apart in a millionth of a second when water molecules inflate the polymers around them.”

A groundbreaking trial to see if it is possible to regenerate the brains of dead people, has won approval from health watchdogs.

A biotech company in the US has been granted ethical permission to recruit 20 patients who have been declared clinically dead from a traumatic brain injury, to test whether parts of their central nervous system can be brought back to life.

Scientists will use a combination of therapies, which include injecting the brain with stem cells and a cocktail of peptides, as well as deploying lasers and nerve stimulation techniques which have been shown to bring patients out of comas.
