RESEARCHERS CREATE NEW ZINC-AIR POUCH CELLS
Zinc-air batteries (ZABs) are among the most promising next-generation battery technologies due to their many advantageous characteristics. Most notably, these batteries have unique half-open structures, a significant theoretical energy density (1,086 and 1,370 Wh kg−1 when including and excluding oxygen, respectively), flexible electrodes and an inherently aqueous electrolyte. Moreover, in contrast with other materials used in batteries, Zinc (Zn) is less harmful for the environment and more abundant.
STUDY TESTS VIABILITY OF TESLA’S 100-YEAR OLD PATENTED DEVICE
A valve invented by engineer Nikola Tesla a century ago is not only more functional than previously realized, but also has other potential applications today, a team of researchers has found after conducting a series of experiments on replications of the early 20th-century design.
US AIR FORCE AUTONOMOUS DRONE SKYBORG COMPLETES FIRST FLIGHT
Last month, the United States Air Force successfully test flew an unnamed aerial vehicle (UAV) called Skyborg, operating on an autonomous hardware/software suite, for the very first time.

DIAMONDS ENGAGE BOTH OPTICAL MICROSCOPY AND MRI FOR BETTER IMAGING
When doctors or scientists want to peer into living tissue, there’s always a trade-off between how deep they can probe and how clear a picture they can get.
QUANTUM COMPUTING: COLD CHIPS CAN CONTROL QUBITS
Researchers and engineers from QuTech in the Netherlands and from Intel Corp., jointly designed and tested a chip to control qubits that can operate at extremely low temperatures, and opens the door to solving the “wiring bottleneck,” an important step toward a scalable quantum computer. Their results are published in the scientific journal Nature.
RESEARCHERS DEVELOP ALGORITHM TO SEE INSIDE MATERIALS WITH SUBATOMIC PARTICLES
The University of Kent’s School of Physical Sciences, in collaboration with the Science and Technology Facilities Council (STFC) and the Universities of Cardiff, Durham and Leeds, have developed an algorithm to train computers to analyze signals from subatomic particles embedded in advanced electronic materials.

PERMAFROST CARBON FEEDBACKS THREATEN GLOBAL CLIMATE GOALS
Since it was first signed more than five years ago, the Paris Agreement has set the bar for the global effort to reduce greenhouse gas emissions, with more than 70 countries taking on ambitious nationally determined contributions that exceed initial commitments laid out in the agreement. However, a new paper released today in Proceedings of the National Academy of Sciences argues that the carbon budget these commitments are based on does not take into account the latest science on Arctic feedback loops, and calls for global leaders to rethink emissions goals.
PART OF THE GREENLAND ICE SHEET MAY BE CLOSE TO A TIPPING POINT
Data from the Jakobshavn drainage basin of the Central-Western Greenland ice sheet reveals that the distinct mark of this part of the ice sheet has reached a tipping point. That is the conclusion by Niklas Boers from Potsdam Institute for Climate Impact Research, Germany and Martin Rypdal from the Arctic University of Norway, after careful studies of the development in melt rates and ice-sheet height changes during the last 140 years. The two authors propose close monitoring of the Greenland ice sheet to assess the situation. The work, published in PNAS today, is part of the TiPES project, coordinated and led by the University of Copenhagen, Denmark, and the Potsdam Institute for Climate Impact Research, Germany.
GREENHOUSE GASES ARE SHRINKING THE STRATOSPHERE
An international team of climate scientists has found evidence showing that human-created greenhouse gases have led to a shrinking stratosphere. In their paper published in the journal Environmental Research Letters, the group describes analyzing data from satellites to create computer models.
? ASTRONOMY & SPACE NEWS??:
SUPERNOVA REMNANT G53.41+0.03 INVESTIGATED IN DETAIL
Astronomers have conducted detailed X-ray observations of a recently discovered supernova remnant (SNR) known as G53.41+0.03. Results of the observational campaign provide important insights into the properties of this object. The study was detailed in a paper published May 7 on the arXiv pre-print server.
SCIENTIST DATED SOME OF THE OLDEST STARS WITH UNPRECEDENTED PRECISION
Scientists have succeeded in dating some of the oldest stars in the galaxy with unprecedented precision by combining data from the stars’ oscillations with information about their chemical composition.
CHINA LANDS ON MARS IN MAJOR ADVANCE FOR ITS SPACE AMBITIONS
China landed a spacecraft on Mars for the first time on Saturday, a technically challenging feat more difficult than a moon landing, in the latest step forward for its ambitious goals in space.

FUTURE SPARKLES FOR DIAMOND-BASED QUANTUM TECHNOLOGY
Marilyn Monroe famously sang that diamonds are a girl’s best friend, but they are also very popular with quantum scientists—with two new research breakthroughs poised to accelerate the development of synthetic diamond-based quantum technology, improve scalability, and dramatically reduce manufacturing costs.
DIRECT-ACTING ANTIVIRAL TO TREAT COVID-19 DEVELOPED IN QLD
An international team of scientists from the Menzies Health Institute Queensland (MHIQ) at Griffith University and from City of Hope, a research and treatment center for cancer, diabetes and other life-threatening diseases in the US, has developed an experimental direct-acting antiviral therapy to treat COVID-19.
A LiDAR DEVICE THE SIZE OF A FINGER NOW AVAILABLE
A nanophotonics-based LiDAR technology developed by a POSTECH research team was presented as an invited paper in Nature Nanotechnology, the leading academic journal in the field of nanoscience and nanoengineering.
