New tool helps researchers study remote glaciers

As warming atmospheric temperatures lead to glacier thinning and retreat around the world, understanding how glaciers are responding to climate change, algal growth, and impurities like dust and black carbon is vital. Understanding ...

Detailed insight into friction: How objects start to slide

Chemists and physicists at the University of Amsterdam shed light on a crucial aspect of friction: how things begin to slide. Using fluorescence microscopy and dedicated fluorescent molecules, they are able to pinpoint how ...

Making mini-magnets that induce a quantum anomalous Hall effect

A new device has been fabricated that can demonstrate the quantum anomalous Hall effect, in which tiny, discrete voltage steps are generated by an external magnetic field. This work may enable extremely low-power electronics, ...

Low-cost disease diagnosis by mapping heart sounds

Aortic valve stenosis occurs when the aortic valve narrows, constricting blood flow from the heart through the artery and to the entire body. In severe cases, it can lead to heart failure. Identifying the condition can be ...

Harvesting resources on Mars with plasmas

An international team of researchers came up with a plasma-based way to produce and separate oxygen within the Martian environment. It's a complementary approach to NASA's Mars Oxygen In-Situ Resource Utilization Experiment, ...

Simulating 3D-AFM images for systems not in equilibrium

Researchers at Kanazawa University report in the Journal of Physical Chemistry Letters how to simulate 3D atomic force microscopy images of out-of-equilibrium systems involving biomolecules. The approach makes use of a celebrated ...

Light polarization creates art, explains mathematical concepts

The polarization of light underpins a variety of recent technological innovations, including 3D cinema and LCDs. In LCDs, tiny electronically controllable liquid crystal elements are sandwiched between polarizers. If, instead, ...

High school students measure Earth's magnetic field from ISS

A group of high school students used a tiny, inexpensive computer to try to measure Earth's magnetic field from the International Space Station, showing a way to affordably explore and understand our planet.

Study illustrates nuances of gravitational pull of ice sheets

It is well known that global warming is causing sea levels to rise via two processes: thermal expansion, when water expands because of its increased temperature, and melting of land-based ice, when meltwater flows into the ...
