Lasers Trigger Magnetism in Atomically Thin Quantum Materials

A cartoon depiction of the light-induced ferromagnetism that the researchers observed in ultrathin sheets of tungsten diselenide and tungsten disulfide. Laser light, shown in yellow, excites an exciton – a bound pair of an electron (blue) and its associated positive charge, also known as a hole (red). This activity induces long range exchange interactions among other holes trapped within the moiré superlattice, orienting their spins in the same direction.Xi Wang/University of Washington

Researchers have discovered that light – in the form of a laser – can trigger a form of magnetism in a normally nonmagnetic material. This magnetism centers on the behavior of electrons...

Jupiter’s Moon has Splendid Dunes

Potential dunes on Jupiter’s moon Io. An analysis indicates that the dark material (lower left) is recently emplaced lava flows, while the repeated, line-like features dominating the image are potential dunes. The bright, white areas may be newly emplaced grains as the lava flows vaporize adjacent frost. Credit: NASA/JPL-Caltech/Rutgers

New way dunes can form on varied celestial surfaces. Scientists have long wondered how Jupiter’s innermost moon, Io, has meandering ridges as grand as any that can be seen in movies like “Dune.” Now, a Rutgers research study has provided a new explanation of how dunes can form even on a surface as icy and roiling as Io’s.

The study, published in the journal Nature Communications, is based on a study of the physical processes controlling grain motion ...

How Air Pollution Alters Lung Tissue, increasing Cancer Susceptibility

Inhaled fine particulate matter (shown here in red) pulls strings of collagen to disturb the immune defence in mice with lung cancer cells. This activity delays the movement of cytotoxic T-cells (purple) as they migrate towards the cancer cells (green) to destroy them. Image credit: Wang et al. 

Scientists have identified a mechanism that explains how fine air pollution particles might cause lung cancer, according to a study published today in eLife.

The findings could lead to new approaches for preventing or treating the initial lung changes that lead to the disease.

Tiny, inhalable fine particulate matter (FPM) found in air pollutants has been recognised as a Group 1 carcinogen and a substantial threat to global health...

Researchers take step toward developing ‘Electric Eye’

Using nanotechnology, scientists have created a newly designed neuromorphic electronic device that endows microrobotics with colorful vision. The newly designed artificial vision device could have far-reaching applications for the fields of medicine, AI, and microrobotics.

Georgia State University researchers have successfully designed a new type of artificial vision device that incorporates a novel vertical stacking architecture and allows for greater depth of color recognition and scalability on a micro-level. The new research is published in the top journal ACS Nano.

“This work is the first step toward our final destination-to develop a micro-scale camera for microrobots,” says assistant professor of Physics Sidong Lei, who led the research...
