Study paves the way for new photosensitive materials

Photocatalysts are useful materials, with a myriad of environmental and energy applications, including air purification, water treatment, self-cleaning surfaces, pollution-fighting paints and coatings, hydrogen production ...

The future looks bright for infinitely recyclable plastic

Plastics are a part of nearly every product we use on a daily basis. The average person in the U.S. generates about 100 kg of plastic waste per year, most of which goes straight to a landfill. A team led by Corinne Scown, ...

ANYbotics reveals full-scale robotic inspection solution

The Swiss robotics company ANYbotics has announced the launch of a new end-to-end robotic inspection system for the energy and industrial processing arenas. This solution aims to answer the call for better safety at production ...

A strategy to rejuvenate dead lithium inside batteries

Li-ion batteries and other emerging lithium-based battery technologies are currently used to power a wide range of devices, including smartphones, laptops, tablets and cameras. Despite their advantages, batteries containing ...

Researchers trace spinal neuron family tree

Spinal cord nerve cells branching through the body resemble trees with limbs fanning out in every direction. But this image can also be used to tell the story of how these neurons, their jobs becoming more specialized over ...

NASA's Mars helicopter makes second flight

NASA successfully carried out a second flight on Mars on Thursday of its mini helicopter Ingenuity, a 52-second sortie that saw it climb to a height of 16 feet (five meters).

Using exoplanets as dark matter detectors

In the continuing search for dark matter in our universe, scientists believe they have found a unique and powerful detector: exoplanets.

Transient grating spectroscopy with ultrafast X-rays

Researchers at the Paul Scherrer Institute PSI have succeeded for the first time in looking inside materials using the method of transient grating spectroscopy with ultrafast X-rays at SwissFEL. The experiment at PSI is a ...

'Stickiness' key to better diagnostics and pharmaceuticals

The 'stickiness', or viscosity, of microscopic liquids can now be measured thousands of times faster than ever before, potentially leading to better understanding of living cells, disease diagnostics and pharmaceutical testing.

Japan strengthens 2030 emissions cut target

Japan aims to cut emissions 46 percent by 2030, significantly more than previously pledged, the country's prime minister announced Thursday ahead of a key US-hosted climate summit.

Can machine learning improve debris flow warning?

Machine learning could provide up an extra hour of warning time for debris flows along the Illgraben torrent in Switzerland, researchers report at the Seismological Society of America (SSA)'s 2021 Annual Meeting.

Plastic: What we eat and breathe

Take a deep breath, drink a glass of water, eat a snack. If you do any of these things, it's likely that you are also inhaling and ingesting tiny particles of plastic, as much as a credit card's weight each week. Plastic ...
