Together with researchers from Ulm and Neuchâtel, Empa will soon be studying material samples on the ISS. The material in question are super-hard and corrosion-resistant alloys of palladium, nickel, copper and phosphorus - also known as "metallic glasses". A high-tech company from La Chaux-de-Fonds, which produces materials for the watch industry, is also involved.
A cross-college collaboration at The University of Alabama in Huntsville (UAH) has developed a self-learning artificial intelligence (AI) platform that uses big data analytics to discover how new pharmaceutical drugs and various molecules work inside living cells.

Using valved respirators to prevent the spread of COVID-19 has been discouraged due to concerns that valves do not effectively filter particles from exhaled air, but few studies actually have looked at this. Now, researchers report in Environmental Science & Technology Letters on their performance.
Researchers reporting in ACS’ Environmental Science & Technology show that some children’s products advertised as water- or stain-resistant contain potentially harmful per- and polyfluoroalkyl substances (PFAS), even items labeled “green” or “nontoxic.”
What do gunpowder, penicillin and Teflon all have in common? They were inventions that took the world by storm, but they were all created by complete accident.
Wet electrolyte could be a key to inexpensive energy storage.
ORNL researchers have developed and tested novel small-molecule antivirals in an effort to design new drugs to treat COVID-19. The so called hybrid inhibitor molecules are made from repurposed drugs used to treat hepatitis C and the original coronavirus outbreak in the early 2000s. The experimental research results show the molecules are similarly as effective as some of the leading drugs on the market today.
New experiments have shown the source of the aurora borealis. Researchers have demonstrated Alfvén waves accelerating electrons under conditions that correspond to Earth’s magnetosphere. The new experiments show that electrons “surf” on the electric field of the Alfvén wave in a plasma. These electrons are the ultimate source of the light we call the aurora borealis.
Polaritons offer the best of two very different worlds. These hybrid particles combine light and molecules of organic material, making them ideal vessels for energy transfer in organic semiconductors. They are both compatible with modern electronics but also move speedily, thanks to their photonic origins.
Large ion clusters known as aggregates are an important emerging topic for research on electrolytes in batteries. The research indicates that aggregates can affect electrolyte properties, including stability and ion transport.
UPTON, NY—Minfang Yeh, a senior scientist at the U.S. Department of Energy’s Brookhaven National Laboratory, has won the American Physical Society’s 2021 Division of Particles and Fields (DPF) Instrumentation Award. The award honors Yeh’s pioneering work in the development and production of high-performance water-based liquid scintillators for particle physics experiments, including metal loaded scintillators for rare process experiments.
Quantum computing holds the potential to be a game-changing future technology in fields ranging from chemistry to cryptography to finance to pharmaceuticals.
Scientists have tried to develop a silver coating for implantable medical devices to combat infection with limited success. In ACS Central Science, one team reports a new, long-acting silver-ion releasing coating that, in rats, prevents bacteria from adhering to implants and then kills them.
Morris Bullock has led PNNL's pursuit of the efficient conversion of electrical energy and chemical bonds through control of electron and proton transfers.
A groundbreaking study published today in JAMA demonstrates significant inconsistencies with pediatric reference intervals, which are essential to high quality pediatric medical testing. Completed by AACC’s laboratory medicine experts, this study identifies some of the most pressing issues in this area, thereby paving the way for the medical community to develop more reliable pediatric reference intervals and vastly improve children’s medical care.
Micropollutants in water often are hormones that accumulate in the environment and may have negative impacts on humans and animals. Researchers of Karlsruhe Institute of Technology (KIT) and Leibniz Institute of Surface Engineering (IOM) in Leipzig have now developed a process for the photocatalytic degradation of these pollutants when they flow through polymer membranes. It is presented in Nature Nanotechnology. Irradiation with light triggers a chemical reaction, as a result of which steroid hormones are degraded on the membranes coated with titanium dioxide.

Irvine, Calif., April 22, 2022 — Physicists at the University of California, Irvine have demonstrated the use of a hydrogen molecule as a quantum sensor in a terahertz laser-equipped scanning tunneling microscope, a technique that can measure the chemical properties of materials at unprecedented time and spatial resolutions.
A geologic formation near Aix-en-Provence, France, is famed as one of the world’s chief treasure troves of fossil species from the Cenozoic Era. Since the late 1700s, scientists there have been unearthing amazingly well-preserved fossilized plants and animals.
The need for negative emissions technologies to address our climate crisis has become increasingly clear. At the rate that our planet is emitting carbon dioxide – adding about 50 gigatons every year – we will have to remove carbon dioxide at the gigaton scale by 2050 in order to achieve “net zero” emissions.
We share the FDA’s goal of alerting the public to the potential misuse of non-invasive prenatal screening (NIPS) tests. This is why we’ve been advocating for the modernization of how laboratory-developed tests (LDTs) are regulated by the Centers for Medicare and Medicaid Services (CMS).
