Phys.org / New method to degrade PFAS 'forever chemicals' found effective in the lab
Per-and poly-fluoroalkyl substances (PFAS) are known as "forever chemicals" because they are notoriously resistant to degradation. Due to their stable chemical structure, PFAS—which are found in thousands of variants—are ...

Phys.org / Half of world's lakes are less resilient to disturbance than they used to be
Nearly half of the world's large lakes have lost resilience, or the ability to bounce back after an abrupt disturbance, in recent decades, according to the first global assessment of long-term changes in lake resilience. ...

Phys.org / Boosting 'natural killer' cell activity could improve cancer therapy
Yale researchers have uncovered a way to make a type of white blood cells known as natural killer cells—which kill infected, damaged, or malignant cells in the body—more effective against cancer. The approach, they say, ...

Phys.org / Researchers use gold membrane to coax secrets out of surfaces
Using a special wafer-thin gold membrane, ETH researchers have made it significantly easier to study surfaces. The membrane makes it possible to measure properties of surfaces that are inaccessible to conventional methods.

Phys.org / Radioactive isotopes trace hidden Arctic currents
The Arctic Ocean is warming four times faster than the rest of the world's oceans, a trend that could potentially spill over to the rest of the world in the form of altered weather patterns and other climate consequences. ...

Phys.org / Quantum annealer improves understanding of quantum many-body systems
Physicists have long been pursuing the idea of simulating quantum particles with a computer that is itself made up of quantum particles. This is exactly what scientists at Forschungszentrum Jülich have done together with ...

Phys.org / Bats use four key tactics for accurate target tracking
The ability of "target tracking," i.e., keeping a target object in sight, is essential for various activities and has improved in animals and machines through the evolution of life and technology, respectively. Because most ...

Phys.org / Study finds strong path dependence in Plio-Pleistocene glaciations through climate model simulations
The climate modeling community has been particularly vexed by the glacial/interglacial cycles of the past three million years, when the Northern Hemisphere oscillated between times with and without large ice sheets.

Phys.org / 3D-printed chip sensor detects foodborne pathogens for safer products
Every so often, a food product is recalled because of some sort of contamination. For consumers of such products, a recall can trigger doubt in the safety and reliability of what they eat and drink. In many cases, a recall ...
