Princeton-led team discovers unexpected quantum behavior in kagome lattice
An international team led by Princeton researchers explored quantum structures called kagome lattices and found insights into the fundamental understanding of quantum order leading to orbital magnetism - that is, magnetism that arises from extended orbital motion of electrons rather than their spin. The findings hint at behaviors that could be precursors of unconventional superconductivity and an anomalous Hall effect.

A new 'twist' to break viscoelastic liquid bridges
Scientists have developed a new method that improves dispensing of viscoelastic fluids - a vital process for circuit board production, 3D printing and other industrial applications. The scientists found that twisting these liquid bridges breaks them in a quicker and cleaner way than the conventional method of stretching them.

Concrete wall seismic test data wins NHERI DesignSafe Dataset Award 2021
The 2010-2011 Canterbury Earthquake Sequence devastated the city of Christchurch, New Zealand, killing 185 and causing widespread damage. University of Auckland engineers conducted extensive testing on concrete walls to understand puzzlingly severe damage to steel reinforcement. The research formed the basis for revisions to structural codes in New Zealand and the US, and its dataset won a NHERI DesignSafe Dataset Award 2021.

Swim first, hunt later: Young Weddell seals need to practice navigating before hunting
Weddell seals, the southernmost born mammal, are known as champion divers. But they don't begin life that way. Cal Poly researchers examined the development of diving behavior in Weddell seal pups and found that they time their dives with their mother but likely do not learn to forage at that time. Instead, they focus their early efforts on learning to swim and navigate under the sea ice.

New models predict fewer lightning-caused ignitions but bigger wildfires by mid century
Human-caused wildfire ignitions in Central Oregon are expected to remain steady over the next four decades and lightning-caused ignitions are expected to decline, but the average size of a blaze from either cause is expected to rise, Oregon State University modeling suggests.

Underwater robot offers new insight into mid-ocean "twilight zone"
An innovative underwater robot known as Mesobot is providing researchers with deeper insight into the vast mid-ocean region known as the "twilight zone." Capable of tracking and recording high-resolution images of slow-moving and fragile zooplankton, gelatinous animals, and particles, Mesobot greatly expands scientists' ability to observe creatures in their mesopelagic habitat with minimal disturbance.

Graphene 'camera' captures real-time electrical activity of beating heart
Scientists today track electrical signals and voltage changes in neurons and muscle cells by labeling individual cells or probing with electrodes. UC Berkeley and Stanford scientists have developed a new type of sensor that employs a sheet of graphene to get a continuous measure of electric field in these tissues. Electric fields change graphene's reflectance. The physicists found a way to amplify and measure the changes caused by action potentials in a beating embryonic chicken heart.

Machine learning can now reduce worry about nanoparticles in food
While crop yield has achieved a substantial boost from nanotechnology in recent years, the alarms over the health risks posed by nanoparticles within fresh produce and grains have also increased. In particular, nanoparticles entering the soil through irrigation, fertilizers and other sources have raised concerns about whether plants absorb these minute particles enough to cause toxicity.

Nematic transition and nanoscale suppression of superconductivity in an iron chalcogenide
Examining an iron chalcogenide high-temperature superconductor, an international team of researchers has found that just before the material fully enters the nematic state, electronic nematicity first appears in nanoscale patches on its surface. In addition, minute stretching of the material, or strain, can induce local nematicity, which in turn suppresses superconductivity, according to a report in Nature Physics.

ALMA discovers earliest gigantic black hole storm
Researchers using the Atacama Large Millimeter/submillimeter Array (ALMA) discovered a titanic galactic wind driven by a supermassive black hole 13.1 billion years ago. This is the earliest-yet-observed example of such a wind to date and is a telltale sign that huge black holes have a profound effect on the growth of galaxies from the very early history of the Universe.

Soaking up the sun: Artificial photosynthesis promises clean, sustainable source of energy
Humans can do lots of things that plants can't do. But plants have one major advantage over humans: They can make energy directly from the sun. That process of turning sunlight directly into usable energy - called photosynthesis - may soon be a feat humans are able to mimic to harness the sun's energy for clean, storable, efficient fuel. If so, it could open a whole new frontier of clean energy.

Cosmic rays: Coronal mass ejections and cosmic ray observations at Syowa Station in the Antarctic
Solar activities, such as CME(Coronal Mass Ejection), cause geomagnetic storm that is a temporary disturbance of the Earth's magnetosphere. Geomagnetic storms can affect GPS positioning, radio communication, and power transmission system. Solar explosions also emit radiation, which can affect satellite failures, radiation exposure to aircraft crew, and space activity. Therefore, it is important to understand space weather phenomena and their impact on the Earth.
