Nanocomponent is a quantum leap for Danish physicists

Posted by in categories: computing, internet, particle physics, quantum physics

University of Copenhagen researchers have developed a nanocomponent that emits light particles carrying quantum information. Less than one-tenth the width of a human hair, the miniscule component makes it possible to scale up and could ultimately reach the capabilities required for a quantum computer or quantum internet. The research result puts Denmark at the head of the pack in the quantum race.

Teams around the world are working to develop quantum technologies. The focus of researchers based at the Center for Hybrid Quantum Networks (Hy-Q) at the University of Copenhagen’s Niels Bohr Institute is on developing quantum communication technology based on light circuits, known as nanophotonic circuits. The UCPH researchers have now achieved a major advancement.

“It is a truly major result, despite the component being so tiny,” says Assistant Professor Leonardo Midolo, who has been working towards this breakthrough for the past five years.

Florida Man Becomes First Person to Live With Advanced Mind-Controlled Robotic Arm

Posted by in categories: biotech/medical, cyborgs, Elon Musk, robotics/AI

Prosthetics have advanced drastically in recent years. The technology’s potential has even inspired many, like Elon Musk, to ask whether we may be living as “cyborgs” in the not-too-far future. For Johnny Matheny of Port Richey, Florida, that future is now. Matheny, who lost his arm to cancer in 2005, has recently become the first person to live with an advanced mind-controlled robotic arm. He received the arm in December and will be spending the next year testing it out.

The arm was developed by Johns Hopkins Applied Physics Lab as part of their program Revolutionizing Prosthetics. The aim of the program, which is funded by the Defense Advanced Research Projects Agency (DARPA), is to create prosthetics that are controlled by neural activity in the brain to restore motor function to where it feels entirely natural. The program is specifically working on prosthetics for upper-arm amputee patients. While this particular arm has been demoed before, Matheny will be the first person to actually live with the prosthesis. The program does hope to have more patients take the tech for a longterm test run, though.

While the prosthetic device is impressive, it’s not a limitless, all-powerful robot arm. Matheney won’t be able to get the arm wet and is not allowed to drive while wearing it. Keeping a few rules in mind, Matheney will otherwise be free to push the tech to the edge of its capabilities, truly exploring what it can do.

World’s first malaria vaccine to go to 360,000 African children

Posted by in categories: biotech/medical, health

Some 360,000 children a year in three African countries will receive the world’s first malaria vaccine as part of a large-scale pilot project, the World Health Organization (WHO) said Tuesday.

Malawi has started vaccinating children under two years of age and Kenya and Ghana will begin using the vaccine in the coming weeks, with health ministries in these countries deciding where it will be used, the WHO said.

Synthetic speech generated from brain recordings

Posted by in categories: biotech/medical, computing, neuroscience

A state-of-the-art brain-machine interface created by UC San Francisco neuroscientists can generate natural-sounding synthetic speech by using brain activity to control a virtual vocal tract—an anatomically detailed computer simulation including the lips, jaw, tongue, and larynx. The study was conducted in research participants with intact speech, but the technology could one day restore the voices of people who have lost the ability to speak due to paralysis and other forms of neurological damage.

Stroke, , and such as Parkinson’s disease, multiple sclerosis, and amyotrophic lateral sclerosis (ALS, or Lou Gehrig’s disease) often result in an irreversible loss of the ability to speak. Some people with severe speech disabilities learn to spell out their thoughts letter-by-letter using assistive devices that track very small eye or facial muscle movements. However, producing text or synthesized speech with such devices is laborious, error-prone, and painfully slow, typically permitting a maximum of 10 words per minute, compared to the 100–150 words per minute of natural speech.

China to build moon station in ‘about 10 years’

Posted by in category: space travel

Beijing plans to send a manned mission to the moon and to build a research station there within the next decade, state media reported Wednesday, citing a top space official.

China aims to achieve space superpower status and took a major step towards that goal when it became the first nation to land a rover on the in January.

It now plans to build a scientific on the moon’s within the next 10 years, China National Space Administration head Zhang Kejian said during a speech marking “Space Day”, the official Xinhua news agency reported.

Imaging system helps surgeons remove tiny ovarian tumors

Posted by in category: biotech/medical

Ovarian cancer is usually diagnosed only after it has reached an advanced stage, with many tumors spread throughout the abdomen. Most patients undergo surgery to remove as many of these tumors as possible, but because some are so small and widespread, it is difficult to eradicate all of them.

Researchers at MIT, working with surgeons and oncologists at Massachusetts General Hospital (MGH), have now developed a way to improve the accuracy of this , called debulking. Using a novel fluorescence imaging system, they were able to find and remove tumors as small as 0.3 millimeters—smaller than a poppy seed—during surgery in mice. Mice that underwent this type of image-guided surgery survived 40 percent longer than those who had tumors removed without the guided system.

“What’s nice about this system is that it allows for real-time information about the size, depth, and distribution of tumors,” says Angela Belcher, the James Mason Crafts Professor of Biological Engineering and Materials Science at MIT, a member of the Koch Institute for Integrative Cancer Research, and the recently appointed head of MIT’s Department of Biological Engineering.

Solving a Math Problem Just Brought Holograms Closer to Reality

Posted by in categories: holograms, mathematics

Holograms are a staple in science fiction, but creating ones detailed enough to have serious applications in the real world has proved difficult. While scientists have been slowly pushing the field of holographic projection forward, they haven’t been able to overcome a problem called cross-talk. However, in a recent paper published in Nature, they have been able to manipulate the shape of light to overcome this, thus allowing them to produce 3D holograms that are orders of magnitude clearer, larger, and more detailed.

What Are Holograms?

Simple holograms are 2D surfaces that produce the illusion of a 3D object when light is shined through it.
