🗞 TECHNOLOGY NEWS💻🔧🖥:
NEW BRAIN-LIKE COMPUTING DEVICE SIMULATES HUMAN LEARNING
Researchers have developed a brain-like computing device that is capable of learning by association.
AI, CAPTAIN! FIRST AUTONOMOUS SHIP PREPARES FOR MAIDEN VOYAGE
The “Mayflower 400″—the world’s first intelligent ship—bobs gently in a light swell as it stops its engines in Plymouth Sound, off England’s southwest coast, before self-activating a hydrophone designed to listen to whales.
A ZERO-GAP GAS DIFFUSION ELECTRODE-BASED ELECTROLYZER WITH IMPROVED STABILITY
A team of researchers from the University of Szeged has developed a zero-gap GDE-based electrolyser that has better stability than others in its category. In their paper published in the journal Nature Energy, the group describes their work, which involved attempting to improve the prospects of using electrolysers as a means for creating fuel sources. Klaas Jan P. Schouten with the University of Amsterdam has published a News & Views piece describing the work in the same journal issue.
🗞 PHYSICS NEWS⚙♨:
RESEARCHERS DEVELOP COMPACT ON-CHIP DEVICE FOR DETECTING ELECTRIC-FIELD WAVEFORMS WITH ATTOSECOND TIME RESOLUTION
Understanding how light waves oscillate in time as they interact with materials is essential to understanding light-driven energy transfer in materials, such as solar cells or plants. Due to the fantastically high speeds at which light waves oscillate, however, scientists have yet to develop a compact device with enough time resolution to directly capture them.
In work that could turn cell phones into sensors capable of detecting viruses and other minuscule objects, MIT researchers have built a powerful nanoscale flashlight on a chip.
‘BAT-SENSE’ TECH GENERATES IMAGES FROM SOUND
By cleverly analyzing the results, the algorithm can deduce the shape, size and layout of a room, as well as pick out in the presence of objects or people. The results are displayed as a video feed which turns the echo data into three-dimensional vision.
🗞 EARTH NEWS🌏:
ANTARCTIC ICE-SHEET MELTING TO LIFT SEA LEVEL HIGHER THAN THOUGHT, STUDY SAYS
Global sea level rise associated with the possible collapse of the West Antarctic Ice Sheet has been significantly underestimated in previous studies, meaning sea level in a warming world will be greater than anticipated, according to a new study from Harvard researchers.
IN A FIRST, SCIENTISTS MAP PARTICLE-LADEN RIVERS IN THE SKY
Windy regions high in the atmosphere can transport pollutants like dust or soot thousands of miles around the world and disrupt everyday life for thousands of people.
MODEL COULD CREATE HURRICANE FORECASTS UP TO 18 MONTHS IN ADVANCE
Every spring, researchers publish their projected forecasts of the upcoming hurricane season—how many storms may form, and how severe they may be. But what if you could create these forecasts up to a year and a half in advance? A new model from North Carolina State University incorporates machine learning to create long-range hurricane forecasts with similar accuracy to those currently in use.
🗞 ASTRONOMY & SPACE NEWS🌪🎇:
RESEARCHERS DISCOVER THE MECHANISM THAT LIKELY GENERATES HUGE WHITE DWARF MAGNETIC FIELDS
A dynamo mechanism could explain the incredibly strong magnetic fields in white dwarf stars according to an international team of scientists, including a University of Warwick astronomer.
MARS HELICOPTER MAKES 4TH FLIGHT, GETS EXTRA MONTH OF FLYING
After proving powered, controlled flight is possible on the Red Planet, NASA’s Mars Ingenuity helicopter has new orders: scout ahead of the Perseverance rover to assist in its search for past signs of microbial life.
THE DALI EXPERIMENT: SEARCHING FOR THE AXION, A PROPOSED COMPONENT OF DARK MATTER
The detection of the axion would mark a key episode in the history of science. This hypothetical particle could resolve two fundamental problems of Modern Physics at the same time: the problema of Charge and Parity in the strong interaction, and the mystery of dark matter. However, in spite of the high scientific interest in finding it, the search at high radio frequency—above 6 GHz—has been almost left aside for the lack of the high sensitivity technology which could be built at reasonable cost. Until now.
🗞 NANOTECHNOLOGY NEWS⛄☃:
SELF-ORGANIZATION OF NANOPARTICLES AND MOLECULES IN PERIODIC LIESEGANG-TYPE STRUCTURES
Chemical organization in reaction-diffusion systems offer a strategy to generate materials with ordered morphologies and architecture. Periodic structures can be formed using molecules or nanoparticles. An emerging frontier in materials science aims to combine nanoparticles and molecules. In a new report on Science Advances, Amanda J. Ackroyd and a team of scientists in chemistry, physics and nanomaterials in Canada, Hungary and the U.S. noted how solvent evaporation from a suspension of cellulose nanocrystals (CNCs) and L-(+)-tartaric acid [abbreviated L-(+)-TA] caused the phase separation of precipitation to result in the rhythmic alteration of CNC-rich, L-(+)-TA rings. The CNC-rich regions maintained a cholesteric structure, while the L-(+)-TA-rich bands formed via radially elongated bundles to expand the knowledge of self-organizing reaction-diffusion systems and offer a strategy to design self-organizing materials.
RESEARCHERS ANALYZE CIRCULATING CURRENTS INSIDE GOLD NANOPARTICLES
According to classical electromagnetism, a charged particle moving in an external magnetic field experiences a force that makes the particle’s path circular. This basic law of physics are exploited in designing cyclotrons that work as particle accelerators. When nanometer-size metal particles are placed in a magnetic field, the field induces a circulating electron current inside the particle. The circulating current in turn creates an internal magnetic field that opposes the external field. This physical effect is called magnetic shielding.
