Infamous for their environmental persistence and potential links to health conditions, per- and polyfluoroalkyl substances (PFAS), often called forever chemicals, are being discovered in unexpected places, including beer. Researchers publishing in ACS’ Environmental Science & Technology tested beers brewed in different areas around the U.S. for these substances. They found that beers produced in parts of the country with known PFAS-contaminated water sources showed the highest levels of forever chemicals.
Ferromagnetic semiconductors, which combine semiconductor and magnetic properties, are key to developing spin-based devices. Previously studied materials, such as (Ga,Mn)As, have Curie temperatures below room temperature, thereby limiting their practical use. Now, researchers from Institute of Science Tokyo and The University of Tokyo have overcome these limitations by utilizing the step-flow growth method, achieving a record-high Curie temperature of 530 K, facilitating the development of stable, room-temperature semiconductor spintronic devices.
If you’ve ever sat waiting at the doctor’s office to give a blood sample, you might have wished there was a way to find the same information without needles.
But for all the medical breakthroughs of the 20th century, the best way to detect molecules has remained through liquids, such as blood. New research from the University of Chicago, however, could someday put a pause on pinpricks. A group of scientists announced they have created a small, portable device that can collect and detect airborne molecules—a breakthrough that holds promise for many areas of medicine and public health.
Examining complex heat transfer processes in detail, even under extreme conditions such as those found in power plants and industrial plants – this is now possible with the COSMOS-H research facility at Karlsruhe Institute of Technology (KIT) which was opened on Thursday, May 8, 2025. For the first time, scientists have an infrastructure at their disposal to investigate flow and boiling phenomena in detail, even under realistic high-pressure conditions.
