A TACTILE SENSING FOOT TO INCREASE THE STABILITY OF LEGGED ROBOTS
In order to effectively navigate real-world environments, legged robots should be able to move swiftly and freely while maintaining their balance. This is particularly true for humanoid robots, robots with two legs and a human-like body structure.
SMALL GENERATOR CAPTURES HEAT GIVEN OFF BY SKIN TO POWER WEARABLE DEVICES
Scientists in China have developed a small, flexible device that can convert heat emitted from human skin to electrical power. In their research, presented April 29 in the journal Cell Reports Physical Science, the team showed that the device could power an LED light in real time when worn on a wristband. The findings suggest that body temperature could someday power wearable electronics such as fitness trackers.
A MODULAR BUILDING PLATFORM FOR THE MOST INGENIOUS OF ROBOTS
A team of scientists from the Max Planck Institute for Intelligent Systems (MPI-IS) have developed a system with which they can fabricate miniature robots building block by building block, which function exactly as required.

UNDERSTANDING THE CHARGE PUMPING AND RELAXATION OF THE CHIRAL ANOMALY IN A DIRAC SEMIMETAL
The 3D Dirac and Weyl semimetals can be characterized by a charge chirality with the parallel or antiparallel locking of electron spin in its momentum. Such materials can exhibit a chiral magnetic effect associated with the near conservation of chiral charge. In this work, Bing Cheng and a research team in physics and astronomy at the Johns Hopkins University and materials science at the University of California, Santa Barbara, used magneto-terahertz spectroscopy to study epitaxial cadmium arsenide (Cd3As2) films—a widely explored material in solid-state physics to extract their conductivities as a function of chiral magnetic effect . When the team applied the field, they noted a markedly sharp Drude response – a highly acclaimed model of electronic transport suggested by physicist Paul Drude more than 100 years ago. The Drude response rose out of the broader background of this system as a definitive signature of a new transport channel consistent with the chiral response. The field independence of the chiral relaxation established that it was set by the approximate conservation of the isospin in the setup.
MACHINE LEARNING ALGORITHM HELPS UNRAVEL THE PHYSICS UNDERLYING QUANTUM SYSTEMS
Scientists from the University of Bristol’s Quantum Engineering Technology Labs (QETLabs) have developed an algorithm that provides valuable insights into the physics underlying quantum systems—paving the way for significant advances in quantum computation and sensing, and potentially turning a new page in scientific investigation.
SILICON MULTIPLEXER CHIP WILL DRIVE NEXT GENERATION COMMUNICATIONS
Researchers from Osaka University, Japan and the University of Adelaide, Australia have worked together to produce the new multiplexer made from pure silicon for terahertz-range communications in the 300-GHz band.
🗞 EARTH NEWS🌏:
THE ARCTIC’S GREENING, BUT IT WON’T SAVE US
There was a hope that as more plants start to grow in Arctic and boreal latitudes as our warming climate makes those regions more hospitable for plants, those photosynthesizing plants would work to help sequester the atmospheric carbon dioxide that helped them flourish in the first place. But new research led by scientists at UC Irvine and Boston University, out in Nature Climate Change, suggests that all the new green biomass is not as large a carbon sink as scientists had hoped.
‘SELF-HEALING’ CONTINENTAL ROOTS HAVE IMPLICATIONS FOR PRECIOUS MINERAL EXPLORATION
A new study led by University of Alberta geologists is shedding light on a fundamental mechanism of how Earth’s continental plates heal, with implications for diamond exploration and locating economically important minerals.
LIGHTNING AND SUBVISIBLE DISCHARGES PRODUCE MOLECULES THAT CLEAN THE ATMOSPHERE
Lightning bolts break apart nitrogen and oxygen molecules in the atmosphere and create reactive chemicals that affect greenhouse gases. Now, a team of atmospheric chemists and lightning scientists have found that lightning bolts and, surprisingly, subvisible discharges that cannot be seen by cameras or the naked eye produce extreme amounts of the hydroxyl radical—OH—and hydroperoxyl radical—HO2.

HUBBLE WATCHES HOW A GIANT PLANET GROWS
Ever made a complete mess in your kitchen while baking? At moments it may look like flour is floating in the air, but once you’ve added plenty of water and formed your dough, the bread becomes more like a ball. A similar process is at work in a far-flung solar system known as PDS 70, except the flour and water are swapped for gas and dust. In the case of planet PDS 70b, gas and dust are slowly being drawn in as this distant world builds mass over millions of years.
HOW LONG IS A DAY ON VENUS? SCIENTISTS CRACK MYSTERIES OF OUR CLOSEST NEIGHBOR
Venus is an enigma. It’s the planet next door and yet reveals little about itself. An opaque blanket of clouds smothers a harsh landscape pelted by acid rain and baked at temperatures that can liquify lead.
CHINA LAUNCHES MAIN PART OF ITS 1ST PERMANENT SPACE STATION
China on Thursday launched the main module of its first permanent space station that will host astronauts long term, the latest success for a program that has realized a number of its growing ambitions in recent years.
🗞 NANOTECHNOLOGY NEWS⛄☃:
TARGETING TUMORS WITH NANOWORMS
Drugs and vaccines circulate through the vascular system reacting according to their chemical and structural nature. In some cases, they are intended to diffuse. In other cases, like cancer treatments, the intended target is highly localized. The effectiveness of a medicine —and how much is needed and the side effects it causes —are a function of how well it can reach its target.
