NTU Singapore scientists invent glue activated by magnetic field
Wednesday, 23 December 2020 07:49Scientists from Nanyang Technological University, Singapore (NTU Singapore), have developed a new way to cure adhesives using a magnetic field. Conventional adhesives like epoxy which are used to bond plastic, ceramics and wood are typically designed to cure using moisture, heat or light. They often require specific curing temperatures, ranging from room temperature up to 80 degrees Celsiu

NASA, UN sign Memorandum of Understanding on Peaceful Uses of Space
Wednesday, 23 December 2020 07:49NASA and the United Nations Office for Outer Space Affairs (UNOOSA) have signed a memorandum of understanding (MOU) pledging cooperation in areas of science and technology to support the peaceful use of outer space. The MOU, signed Thursday, Dec. 17, brings together NASA's wealth of publicly available Earth observation data and dynamic exploration opportunities with UNOOSA's unique positio
Ultracold atoms reveal a new type of quantum magnetic behavior
Wednesday, 23 December 2020 07:49A new study illuminates surprising choreography among spinning atoms. In a paper appearing in the journal Nature, researchers from MIT and Harvard University reveal how magnetic forces at the quantum, atomic scale affect how atoms orient their spins. In experiments with ultracold lithium atoms, the researchers observed different ways in which the spins of the atoms evolve. Like tippy balle
Compressive fluctuations heat ions in space plasma
Wednesday, 23 December 2020 07:49New simulations carried out in part on the ATERUI II supercomputer in Japan have found that the reason ions exist at higher temperatures than electrons in space plasma is because they are better able to absorb energy from compressive turbulent fluctuations in the plasma. These finding have important implications for understanding observations of various astronomical objects such as the images of
NASA finds what a glacier's slope reveals about Greenland ice sheet thinning
Wednesday, 23 December 2020 07:49As glaciers flow outward from the Greenland Ice Sheet, what lies beneath them offers clues to their role in future ice thinning and sea-level rise contribution. Outlet glaciers are rivers of ice flowing within the cracks of the bedrock and draining into the surrounding sea. They retreat and start to thin as climate warms, and this thinning works its way toward the center of the ice sheet.
Mapping out a transient atom
Wednesday, 23 December 2020 07:49An international team from Germany, Sweden, Russia and the USA, led by scientists from European XFEL, has published the results of an experiment that could provide a blueprint for the analysis of transitions states in atoms and molecules. This would open up new opportunities to gain insights into important processes such as photocatalysis, elementary steps in photosynthesis and radiation damage.
Brazilian researcher experiments with electron-plasma interactions
Wednesday, 23 December 2020 07:49A paper on research conducted by Meirielen Caetano de Sousa, postdoctoral fellow at the University of Sao Paulo's Physics Institute (IF-USP) in Brazil, is highlighted as Editor's Pick in the September issue of Physics of Plasmas, published by the American Institute of Physics with the cooperation of The American Physical Society. The paper, entitled "Wave-particle interactions in a long tr
Earthlings and astronauts chat away, via ham radio
Tuesday, 22 December 2020 20:37The International Space Station cost more than $100 billion. A ham radio set can be had for a few hundred bucks.
Perhaps that explains, in part, the appeal of having one of humankind's greatest scientific inventions communicate with Earth via technology that's more than 100 years old. But perhaps there's a simpler explanation for why astronauts and ham radio operators have been talking, and talking, for years.
NASA astronaut Doug Wheelock was just a few weeks into his six-month mission at the space station when feelings of isolation began to set in.
Wheelock would be separated from loved ones, save for communication via an internet phone, email or social media. At times, the stress and tension of serving as the station's commander could be intense.
One night, as he looked out a window at the Earth below, he remembered the space station's ham radio. He figured he'd turn it on—see if anyone was listening.
"Any station, any station, this is the International Space Station," Wheelock said.
A flood of voices jumbled out of the airwaves.
Astronauts aboard the space station often speak to students via ham radio, which can also be used in emergencies, but those are scheduled appearances.

A-68A iceberg thinning at 2.5 cm per day
Tuesday, 22 December 2020 15:30Latest images reveal that the A-68A iceberg has shattered into multiple pieces, with two large fragments of ice breaking off from the main berg and floating away in the open ocean. Scientists using satellite data have not only been monitoring the iceberg’s journey across the South Atlantic Ocean, but have been studying the iceberg’s ever-changing shape.
Using AI to count and map craters on the moon
Tuesday, 22 December 2020 15:01A team of researchers affiliated with several institutions in China, one from Italy and one from Iceland has used a machine-learning artificial intelligence application to count and note the location of over 100,000 craters on the moon. In their paper published in the journal Nature Communications, the group describes programming their system to recognize craters by training it with data collected by Chinese lunar orbiters.
Prior work identifying and mapping craters on the moon has tended to be a slow process—it has generally been done by hand, with researchers studying photographs and transferring those observations to maps or moon globes. In this new effort, the researchers have found a way to dramatically speed up the process by teaching a computer to identify craters and then to count them.
Teaching a computer to recognize craters on the moon has been a difficult process due to the many forms craters can take. Not all are round, and they are of different ages, which means defining characteristics have eroded over long periods of time.
