Arsenic's atmospheric journey: New methods reveal environmental toxin's transport pathways

On the Pic du Midi in the Pyrenees, ETH researchers have analyzed particulate matter, clouds and rainwater for traces of arsenic. Using newly developed measurement methods, they have elucidated the transport pathways of the ...

Spiders 'smell' with their legs, new research finds

Spiders have always lived alongside humans, so it's surprising how much we still don't know about them. One long-standing mystery was related to how spiders detect smells. Now, our latest research has finally uncovered the ...

Antimatter propulsion is still far away, but it could change everything

Getting places in space quickly has been the goal of propulsion research for a long time. Rockets, our most common means of doing so, are great for providing lots of force but are extraordinarily inefficient. Other options ...

Garden produce grown near Fayetteville works fluorochemical plant contains GenX, other PFAS

Residential garden produce grown near the Fayetteville Works fluorochemical plant can expose those who consume it to per- and polyfluoroalkyl substances (PFAS), according to a new study conducted by researchers from North ...

Experts study where microplastics are winding up—and what risks they pose

While photos of littered beaches and floating garbage patches are unsettling, perhaps the most problematic plastic is barely visible to the naked eye. Called microplastics—chunks less than 5 millimeters across—these bits ...

New technologies could help destroy persistent 'forever chemicals'

Scientists and engineers are developing new ways to destroy per- and poly-fluoroalkyl substances (PFAS) efficiently and sustainably. This class of chemicals is known as "forever chemicals" because PFAS persist and accumulate ...
