Scientists from NUST MISIS have presented an innovative autonomous power source: a compact atomic battery that can last up to 20 years. Due to the original 3D structure of the beta-voltaic element, its dimensions have decreased by 3x.

The original device uses the microchannel 3D structure of a nickel beta-voltaic element. Its peculiarity is that the radioactive element is applied on both sides of the planar p-n junction, which simplifies the cell manufacturing technology, as well as the control of the reverse current that steals the battery power. The special microchannel structure provides an increase in the effective conversion area of the beta radiation by 14 times, which results in an overall increase of current.

Asteroid 2018 VP₁ may be heading for Earth. But there’s no need to worry

Social media around the world lit up over the weekend, discussing the possibility that an asteroid (known as 2018 VP₁) could crash into Earth on November 2. But you can rest easy. The asteroid does not pose a threat to life on Earth. Most likely, it will sail harmlessly past our planet. At worst, it will burn up harmlessly in our atmosphere and create a firework show for some lucky Earthlings.

So, what’s the story?

Our story begins a couple of years ago, on November 3, 2018. That night, the Zwicky Transient Facility at Palomar Observatory in Southern California discovered a faint new “near-Earth asteroid”—an object whose orbit can approach, or cross, that of our planet.

At the time...

Microbiome-derived inosine modulates response to checkpoint inhibitor immunotherapy. Science, 2020; eabc3421 DOI

Researchers with the Snyder Institute for Chronic Diseases at the Cumming School of Medicine (CSM) have discovered which gut bacteria help our immune system battle cancerous tumours and how they do it. The discovery may provide a new understanding of why immunotherapy, a treatment for cancer that helps amplify the body’s immune response, works in some cases, but not others. The findings, published in Science, show combining immunotherapy with specific microbial therapy boosts the ability of the immune system to recognize and attack cancer cells in some melanoma, bladder and colorectal cancers.

Quantum Researchers create an Error-Correcting Cat

Illustration by Michael S. Helfenbein

Yale physicists have developed an error-correcting cat – a new device that combines the Schrödinger’s cat concept of superposition (a physical system existing in two states at once) with the ability to fix some of the trickiest errors in a quantum computation.

It is Yale’s latest breakthrough in the effort to master and manipulate the physics necessary for a useful quantum computer: correcting the stream of errors that crop up among fragile bits of quantum information, qubits, while performing a task.

A new study reporting on the discovery appears in the journal Nature. The senior author is Michel Devoret, Yale’s F.W. Beinecke Professor of Applied Physics and Physics...
