Diamond-Based Quantum Accelerator Puts #Qubits in a Server Rack.
The startup Quantum Brilliance recently announced that they have developed a market-ready, diam… See More.
Its makers envision this device growing to 50+ qubits and fitting aboard satellites, autonomous vehicles.
As the first papers under these mandates are published, Plan S supporters say it’s the start of a journey towards open science. But most research funders haven’t signed up yet, and negotiations over the plan have produced a complex landscape of options to avoid paywalls. Here’s what the initiative means for scientists and journals — and some of the controversies that will play out in 2021 and beyond.
The push to remove journal paywalls officially started this year. Here’s how it works.
As they researched why the avalanche occurred with such force, researchers studying climate change pored over images taken in the days and weeks before and saw that ominous cracks had begun to form in the ice and snow. Then, scanning photos of a nearby glacier, they noticed similar crevasses forming, touching off a scramble to warn local authorities that it was also about to come crashing down.
The images of the glaciers came from a constellation of satellites no bigger than a shoebox, in orbit 280 miles up. Operated by San Francisco-based company Planet, the satellites, called Doves, weigh just over 10 pounds each and fly in “flocks” that today include 175 satellites. If one fails, the company replaces it, and as better batteries, solar arrays and cameras become available, the company updates its satellites the way Apple unveils a new iPhone.
The revolution in technology that transformed personal computing, put smart speakers in homes and gave rise to the age of artificial intelligence and machine learning is also transforming space. While rockets and human exploration get most of the attention, a quiet and often overlooked transformation has taken place in the way satellites are manufactured and operated. The result is an explosion of data and imagery from orbit.
A new way to harvest power from 5G networks could make many of the batteries that power our devices a thing of the past, researchers say.

The researchers have developed a flexible Rotman lens-based rectifying antenna (rectenna) system capable, for the first time, of millimeter-wave harvesting in the 28-GHz band. The Rotman lens is key for beamforming networks and is frequently used in radar surveillance systems to see targets in multiple directions without physically moving the antenna system.

Using intuition, educated guesswork and computer simulations, condensed matter physicists have become better at figuring out which quasiparticles are theoretically possible. Meanwhile in the lab, as physicists push novel materials to new extremes, the quasiparticle zoo has grown quickly and become more and more exotic. “It really is a towering intellectual achievement,” said Natelson.
Recent discoveries include pi-tons, immovable fractons and warped wrinklons. “We now think about quasiparticles with properties that we never really dreamt of before,” said Steve Simon, a theoretical condensed matter physicist at the University of Oxford.
Here are a few of the most curious and potentially useful quasiparticles.
Black holes seemed to come only in sizes small and XXL. A new search strategy has uncovered a black hole of “intermediate” mass, raising hopes of more to come.
U.S. policymakers have spent trillions of dollars to mitigate the effects of Covid-19. But the answer to preventing the next pandemic altogether lies elsewhere.
These plants suck metals from the soil at amazing rates. Scientists hope farming the plants could provide an environmentally-friendly alternative to mining.
Researchers in China have designed a new bio-hybrid microbot, able to cross the blood-brain barrier and deliver drugs directly to brain tumours.
