🗞 TECHNOLOGY NEWS💻🔧🖥:
SCIENTISTS DEVELOP NEW TYPE OF ARTIFICIAL MUSCLE INSPIRED BY DNA SUPERCOILING
University of Wollongong (UOW) researchers have mimicked the supercoiling properties of DNA to develop a new type of artificial muscle for use in miniature robot applications. Their research is published today in Science Robotics.
CAN THE ‘BELIEF PROPAGATION’ ALGORITHM ACCURATELY DESCRIBE COMPLEX NETWORKED SYSTEMS?
A messaging-passing algorithm known as “belief propagation” can be used to analyze large systems by breaking them down into smaller pieces and ensuring all of the smaller solutions are consistent with each other. To model the spread of disease when people are in close contact, for example, researchers tend to explore infected individuals’ network of contacts because they are large systems.
HOW TO KEEP AUTOMATED ELECTRIC VEHICLES SAFE
Having your social media account hacked is a pain. Having your credit card account hacked can be devastating. Having your new electric vehicle hacked could be disastrous.
🗞 PHYSICS NEWS⚙♨:
SCIENTISTS HARNESS MOLECULES INTO SINGLE QUANTUM STATE
Researchers have big ideas for the potential of quantum technology, from unhackable networks to earthquake sensors. But all these things depend on a major technological feat: being able to build and control systems of quantum particles, which are among the smallest objects in the universe.
MAPPING THE ELECTRONIC STATES IN AN EXOTIC SUPERCONDUCTOR
Scientists characterized how the electronic states in a compound containing iron, tellurium, and selenium depend on local chemical concentrations. They discovered that superconductivity (conducting electricity without resistance), along with distinct magnetic correlations, appears when the local concentration of iron is sufficiently low; a coexisting electronic state existing only at the surface (topological surface state) arises when the concentration of tellurium is sufficiently high. Reported in Nature Materials, their findings point to the composition range necessary for topological superconductivity. Topological superconductivity could enable more robust quantum computing, which promises to deliver exponential increases in processing power.
HELPING SYMMETRIC QUANTUM SYSTEMS SURVIVE IN AN IMPERFECT WORLD
Symmetry principles of classical physics that help keep our solar system stable have an intriguing counterpart in the quantum world, according to new research by a team of physicists from Australia, Italy and Japan.
🗞 EARTH NEWS🌏:
CAVE DEPOSITS SHOW SURPRISING SHIFT IN PERMAFROST OVER THE LAST 400,000 YEARS
Nearly one quarter of the land in the Northern Hemisphere, amounting to some 9 million square miles, is layered with permafrost—soil, sediment, and rocks that are frozen solid for years at a time. Vast stretches of permafrost can be found in Alaska, Siberia, and the Canadian Arctic, where persistently freezing temperatures have kept carbon, in the form of decayed bits of plants and animals, locked in the ground.
DEEP UNDER THE OCEAN, MICROBES ARE ACTIVE AND POISED TO EAT WHATEVER COMES THEIR WAY
The subseafloor constitutes one of the largest and most understudied ecosystems on Earth. While it is known that life survives deep down in the fluids, rocks, and sediments that make up the seafloor, scientists know very little about the conditions and energy needed to sustain that life.
RESEARCHERS FIND HOW TINY PLASTICS SLIP THROUGH THE ENVIRONMENT
Washington State University researchers have shown the fundamental mechanisms that allow tiny pieces of plastic bags and foam packaging at the nanoscale to move through the environment.
🗞 ASTRONOMY & SPACE NEWS🌪🎇:
SCIENTISTS DON SPACESUITS TO EXPLORE HAWAIIAN LAVA TUBES AS IF THEY WERE ON MARS
Imagine trying to pick up a pebble or scrape microbes off a cave wall in a bulky spacesuit with puffy gloves on, under a time constraint because you don’t want to run out of oxygen. That’s what the analog astronauts do daily at the HI-SEAS moonbase habitat in Hawaii as they prepare for future missions to the moon and Mars, says Michaela Musilova of the International MoonBase Alliance (IMA) and director of HI-SEAS, the Hawaii Space Exploration Analog and Simulation.
RADIO ASTRONOMERS DISCOVER 8 NEW MILLISECOND PULSARS
A group of astronomers has discovered eight millisecond pulsars located within the dense clusters of stars, known as “globular clusters,” using South Africa’s MeerKAT radio telescope.
NEW COMPUTER MODEL HELPS BRINGS THE SUN INTO THE LABORATORY
Every day, the sun ejects large amounts of a hot particle soup known as plasma toward Earth where it can disrupt telecommunications satellites and damage electrical grids. Now, scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and Princeton University’s Department of Astrophysical Sciences have made a discovery that could lead to better predictions of this space weather and help safeguard sensitive infrastructure.
🗞 NANOTECHNOLOGY NEWS⛄☃:
RESEARCHERS USE A NANOSCALE SYNTHETIC ANTIFERROMAGNET TO TOGGLE NONLINEAR SPIN DYNAMICS
Researchers at the University of California, Riverside, have used a nanoscale synthetic antiferromagnet to control the interaction between magnons—research that could lead to faster and more energy-efficient computers.
A PATH TO GRAPHENE TOPOLOGICAL QUBITS
In the quantum realm, electrons can group together to behave in interesting ways. Magnetism is one of these behaviors that we see in our day-to-day life, as is the rarer phenomena of superconductivity. Intriguingly, these two behaviors are often antagonists, meaning that the existence of one of them often destroys the other. However, if these two opposite quantum states are forced to coexist artificially, an elusive state called a topological superconductor appears, which is exciting for researchers trying to make topological qubits.
