A TECHNIQUE TO PLAN PATHS FOR MULTIPLE ROBOTS IN FLEXIBLE FORMATIONS
Multi-robot systems have recently been used to tackle a variety of real-world problems, for instance, helping human users to monitor environments and access secluded locations. In order to navigate unknown and dynamic environments most efficiently, these robotic systems should be guided by path planners, which can identify collision-free trajectories for individual robots in a team.
HIBERNATION AND TRASH FEATURES ABOUND FOR THE UPCOMING ANDROID 12
Among other features, the new Android version 12 will both automatically set unused apps to idle mode to provide more space as well as support a trash bin for deleted files.
BRAIN-ON-A-CHIP WOULD NEED LITTLE TRAINING
A neural network that mimics the biology of the brain can be loaded onto a microchip for faster and more efficient artificial intelligence.

HOLOGRAPHIC METASURFACE GAS SENSORS FOR INSTANTANEOUS VISUAL ALARMS
Biological and chemical substances can be rapidly detected in real-time for public health and environmental monitoring purposes. In a new report now on Science Advances, Inki Kim and a research team in mechanical engineering, materials science and electrical engineering in the Republic of Korea and in Pakistan proposed a compact sensor platform to integrate liquid crystals (LCs) and holographic metasurfaces to sense the existence of a volatile gas, and then provide an immediate visual holographic alarm. The team combined the setup to form ultracompact gas sensors without complex instruments in order to detect gas via visual cues. The researchers proved the applicability of the compact sensors by integrating the metasurface-based gas sensor on safety goggles via a one-step nanocasting process.
FLUSHING A PUBLIC TOILET? DON’T LINGER, BECAUSE AEROSOLIZED DROPLETS DO
Flushing a toilet can generate large quantities of microbe-containing aerosols depending on the design, water pressure or flushing power of the toilet. A variety of pathogens are usually found in stagnant water as well as in urine, feces and vomit. When dispersed widely through aerosolization, these pathogens can cause Ebola, norovirus that results in violent food poisoning, as well as COVID-19 caused by SARS-CoV-2.
COMBINING LIGHT, SUPERCONDUCTORS COULD BOOST AI CAPABILITIES
As artificial intelligence has attracted broad interest, researchers are focused on understanding how the brain accomplishes cognition so they can construct artificial systems with general intelligence comparable to humans’ intelligence.
? EARTH NEWS?:
ROCK GLACIERS WILL SLOW HIMALAYAN ICE MELT
Some Himalayan glaciers are more resilient to global warming than previously predicted, new research suggests.
CAN EXTREME MELT DESTABILIZE ICE SHEETS?
Nearly a decade ago, global news outlets reported vast ice melt in the Arctic as sapphire lakes glimmered across the previously frozen Greenland Ice Sheet, one of the most important contributors to sea-level rise. Now researchers have revealed the long-term impact of that extreme melt.
NASA STUDY PREDICTS LESS SAHARAN DUST IN FUTURE WINDS
During 2020, global average surface temperatures were the hottest on record, tying with 2016 as the warmest recorded year. Last year was also the most active hurricane season to date, with many storms quickly intensifying. Temperature and weather systems each interact with, and are influenced by, a multitude of Earth systems, each affected by the warming climate. One of those is the global transport of massive dust plumes from one continent to another.
? ASTRONOMY & SPACE NEWS??:
ASTRONAUTS’ MENTAL HEALTH RISKS TESTED IN THE ANTARCTIC
Astronauts who spend extended time in space face stressors such as isolation, confinement, lack of privacy, altered light-dark cycles, monotony and separation from family. Interestingly, so do people who work at international research stations in Antarctica, where the extreme environment is characterized by numerous stressors that mirror those present during long-duration space exploration.
ASTRONAUTS FLYING REUSED SPACEX ROCKET, CAPSULE FOR 1ST TIME
For the first time, NASA is putting its trust in a recycled SpaceX rocket and capsule for a crew.
RUSSIA SAYS TO LAUNCH OWN SPACE STATION IN 2025
Russia’s space agency said Tuesday it hoped to launch its own orbital station in 2025 as Moscow considers withdrawing from the International Space Station programme to go it alone.
? NANOTECHNOLOGY NEWS⛄☃:
SURPRISING IONIC AND FLOW BEHAVIORS WITH FUNCTIONALIZED NANOCHANNELS
Nanochannels have important applications in biomedicine, sensing, and many other fields. Though engineers working in the field of nanotechnology have been fabricating these tiny, tube-like structures for years, much remains unknown about their properties and behavior.
2D NANOMATERIAL MXENE: THE PERFECT LUBRICANT FOR ROVERS
You can lubricate a bicycle chain with oil, but what do you do with a Mars rover or a red-hot conveyor belt in the steel industry? Very special nanomaterials have now been studied by the TU Wien together with research groups from Saarbrücken (Germany), Purdue University in the U.S. and the Universidad de Chile (Santiago, Chile).
RESEARCH DEMONSTRATES HOW SMALL AMOUNTS OF STRAIN CAN BE USED TO CONTROL A MATERIAL’S PROPERTIES
New research on an atomically-thin semiconductor demonstrates how a material’s magnetism can be controlled using small amounts of strain. Published in Nature Nanotechnology, this study provides key insights for applications ranging from new spintronic devices to faster hard drives. This research was conducted by graduate student Zhuoliang Ni and led by assistant professor Liang Wu in collaboration with Penn’s Charlie Kane and Eugene Mele, as well as researchers from the University of Tennessee, Knoxville, Texas A&M University, the University of Fribourg, and Oak Ridge National Laboratory.
