Evidence Found for a New Fundamental Particle

Posted by in category: particle physics

An experiment at the Fermi National Accelerator Laboratory near Chicago has detected far more electron neutrinos than predicted — a possible harbinger of a revolutionary new elementary particle called the sterile neutrino, though many physicists remain skeptical.

Quantum Computing Key Could Protect Blockchain Security

Posted by in categories: bitcoin, computing, quantum physics, security

Although blockchain is traditionally seen as secure, it is vulnerable to attack from quantum computers. Now, a team of Russian researchers say they have developed a solution to the quantum-era blockchain challenge, using quantum key distribution (QKD).

Quantum computers are different from binary digital electronic computers based on transistors. Whereas common digital computing requires that the data be encoded into binary digits (bits), each of which is always in one of two definite states (0 or 1), quantum computation uses quantum bits, which can have more by being in superpositions of states.

Writing in the journal Quantum Science and Technology, the researchers set out a quantum-safe blockchain platform that uses QKD to achieve secure authentication.

Prototype nuclear battery packs 10 times more power

Posted by in categories: biotech/medical, nuclear energy, robotics/AI, space travel

Russian researchers from the Moscow Institute of Physics and Technology (MIPT), the Technological Institute for Superhard and Novel Carbon Materials (TISNCM), and the National University of Science and Technology MISIS have optimized the design of a nuclear battery generating power from the beta decay of nickel-63, a radioactive isotope. Their new battery prototype packs about 3,300 milliwatt-hours of energy per gram, which is more than in any other nuclear battery based on nickel-63, and 10 times more than the specific energy of commercial chemical cells. The paperwas published in the journal Diamond and Related Materials.

Conventional batteries

Ordinary batteries powering clocks, flashlights, toys, and other compact autonomous electrical devices use the energy of so-called redox chemical reactions. In them, electrons are transferred from one electrode to another via an electrolyte. This gives rise to a potential difference between the electrodes. If the two battery terminals are then connected by a conductor, electrons start flowing to remove the potential difference, generating an electric current. Chemical batteries, also known as galvanic cells, are characterized by a high power density — that is, the ratio between the power of the generated current and the volume of the battery. However, chemical cells discharge in a relatively short time, limiting their applications in autonomous devices. Some of these batteries, called accumulators, are rechargeable, but even they need to be replaced for charging. This may be dangerous, as in the case of a cardiac pacemaker, or even impossible, if the battery is powering a spacecraft.

World’s First 3D-Printed Concrete Housing Project to be Built in Eindhoven

Posted by in categories: 3D printing, habitats

The Dutch city of Eindhoven is to host the world’s first commercial housing project based on 3D-concrete printing, with the first of five planned houses due to start construction this year. The units were developed by a collaborative team including the Eindhoven University of Technology and will be purchased and let out by a real estate company upon completion.

The first house will be a single-floor, three-room house measuring 1000 square feet (95 square meters), to be followed by four multi-story units. The irregular shape of the buildings is based on “erratic blocks in the green landscape,” made possible due to the flexibility of form permitted by 3D-printing.

World’s first 3D-printed cornea made from algae and human stem cells

Posted by in categories: 3D printing, bioengineering, biotech/medical, cyborgs, transhumanism

The human eye is a remarkably sophisticated organ and like the lens to a camera, it’s the cornea that focuses the flood of photons into a perceptible image. But for an estimated 15 million people around the world, eye disease and trauma make surgery the only path to clear vision.

In the next few years, artificial corneas may become more accessible thanks to new research out of Newcastle University in the United Kingdom. There, researchers mixed stem cells from the cornea of a healthy donor with collagen and algae molecules to create a bio-ink, which they 3D-printed into an artificial cornea. The research is currently just a proof-of-concept but lays the groundwork for future techniques to create low-cost, easy-to-produce bionic eyes.
