Spotlight Stories Headlines
🗞 TECHNOLOGY NEWS💻🔧🖥:
POLISH FIRM OPENS CUTTING-EDGE SOLAR ENERGY PLANT
A Polish company on Friday launched the world’s first industrial production line of solar panels based on groundbreaking perovskite technology, which could revolutionise access to solar power.
RARE EARTH SUPPLY DISRUPTIONS HAVE LONG-RANGE IMPACTS, COMPUTER MODEL SHOWS
Rare earth materials are essential to a variety of industries. A new study from Argonne explores the effects of supply disruptions such as mine shutdowns.
BEST WAYS TO CUT CARBON EMISSIONS FROM THE CEMENT INDUSTRY EXPLORED
A new Imperial report identifies alternative materials and carbon capture technologies as critical in decarbonising the cement industry.
🗞 PHYSICS NEWS⚙♨:
RESEARCHERS SEE ATOMS AT RECORD RESOLUTION
In 2018, Cornell researchers built a high-powered detector that, in combination with an algorithm-driven process called ptychography, set a world record by tripling the resolution of a state-of-the-art electron microscope.
NEW DETECTOR FINDS GAMMA RAYS FROM SURPRISING COSMIC SOURCES
Astrophysicist Cao Zhen opens a steel hatch on a windswept Tibetan Plateau and climbs down a ladder into inky darkness. His flashlight picks out a boat floating on a pool of purified water above thousands of glittering orbs the size of beachballs.
A NEW SPINTRONIC PHENOMENON: CHIRAL-SPIN ROTATION FOUND IN NON-COLLINEAR ANTIFERROMAGNET
Researchers at Tohoku University and the Japan Atomic Energy Agency (JAEA) have discovered a new spintronic phenomenon—a persistent rotation of chiral-spin structure.
🗞 EARTH NEWS🌏:
PLUTONIUM PARTICLES FROM NUCLEAR TESTING MORE COMPLEX THAN PREVIOUSLY THOUGHT
More than 100 kg of highly toxic uranium (U) and plutonium (Pu) was dispersed in the form of tiny ‘hot’ radioactive particles after the British detonated nine atomic bombs in remote areas of South Australia, including Maralinga.
SAND’S URBAN ROLE DEMANDS KEY PART ON SUSTAINABILITY STAGE
Over 20 Indonesian islands mysteriously disappear. One of the world’s deadliest criminal syndicates rises to power. Eight cities the size of New York will be built every year for the next three decades. What connects them is sand, embedded in the concrete of nearly all of the world’s buildings, roads, and cities, the glass in the windows, laptops and phone screens, and COVID-19 vaccine vials.
ARCTIC SEA ICE SUCCUMBS TO ATLANTIFICATION
With alarm bells ringing about the rapid demise of sea ice in the Arctic Ocean, satellite data have revealed how the intrusion of warmer Atlantic waters is reducing ice regrowth in the winter. In addition, with seasonal ice more unpredictable than ever, ESA’s SMOS and CryoSat satellites are being used to improve sea-ice forecasts, which are critical for shipping, fisheries and indigenous communities, for example.
🗞 ASTRONOMY & SPACE NEWS🌪🎇:
SALTS COULD BE IMPORTANT PIECE OF MARTIAN ORGANIC PUZZLE, SCIENTISTS FIND
A NASA team has found that organic salts are likely present on Mars. Like shards of ancient pottery, these salts are the chemical remnants of organic compounds, such as those previously detected by NASA’s Curiosity rover. Organic compounds and salts on Mars could have formed by geologic processes or be remnants of ancient microbial life.
TARDIGRADES SURVIVE IMPACTS OF UP TO 825 METERS PER SECOND
A pair of researchers at the University of Kent has found that tardigrades are able to survive impacts at speeds of up to 825 meters per second. In their paper published in the journal Astrobiology, Alejandra Traspas and Mark Burchell describe experiments they conducted that involved firing canisters containing tardigrades at high speeds at sand targets.
LANDING ON MARS IS DIFFICULT, OFTEN FAILS, AND WILL NEVER BE RISK-FREE
China’s rover Zhurong, named after the mythological fire god, successfully touched down on Mars on May 14—the first time that China has successfully landed a rover on the red planet.
🗞 NANOTECHNOLOGY NEWS⛄☃:
NANOPARTICLES: THE COMPLEX RHYTHM OF CHEMISTRY
Most commercial chemicals are produced using catalysts. Usually, these catalysts consist of tiny metal nanoparticles that are placed on an oxidic support. Similar to a cut diamond, whose surface consists of facets oriented in different directions, a catalytic nanoparticle also possesses crystallographically different facets—and these facets can have different chemical properties.
GREEN LIGHT ON GOLD ATOMS: NANO-ANTENNAS MAKE NANO-DEFECTS VISIBLE TO THE NAKED EYE
Because individual atoms or molecules are 100 to 1000 times smaller than the wavelength of visible light, it is notoriously difficult to collect information about their dynamics, especially when they are embedded within larger structures.
NEW METHOD FOR OBSERVES GRAPHENE GROWING USING STANDARD ELECTRON MICROSCOPE
Researchers from the University of Surrey have revealed a new method that enables common laboratory scanning electron microscopes to see graphene growing over a microchip surface in real time.
