Scientists have developed a new efficient catalyst for the most challenging part of “water splitting,” a series of two simultaneous electrochemical reactions that generate hydrogen gas, a green energy source, from water. The new catalyst was designed based on theoretical predictions and validated in laboratory tests and industrially relevant demonstrations.
In a significant leap for aerospace and mechanical engineering, researchers have developed a cutting-edge bidirectional energy-controlled piezoelectric shunt damping technology. This breakthrough not only significantly enhances the suppression of vibration amplitudes in mechanical systems without external power but also harnesses electrical energy, heralding a new era of self-powered solutions.
The exhaust heat generated by a fusing plasma in a commercial-scale reactor may not be as damaging to the vessel’s innards as once thought, according to new research about escaping plasma particles made by researchers at the Princeton Plasma Physics Laboratory, Oak Ridge National Laboratory and ITER Organization (ITER).
A new study by an international team of researchers, published today in Nature Climate Change, has revealed significant progress in the drive to reduce atmospheric levels of chemicals that destroy the Earth’s protective ozone layer, confirming the success of historic regulations limiting their production and use. Empa scientists contributed to this study with measurements from the high-alpine research station at Jungfraujoch.
Today, researchers are developing ways to accelerate discovery by combining automated experiments, artificial intelligence and high-performance computing. A novel tool developed at Oak Ridge National Laboratory that leverages those technologies has demonstrated that AI can influence materials synthesis and conduct associated experiments without human supervision.
The hearts of pregnant rats with high blood pressure increase in size more than rats experiencing a normal pregnancy, according to new computer model predictions.
Researchers have developed a new excitation modality for studying tiny molecules in super detail. The technique, known as MINFLUX, works by shining a patterned light on the molecule. This new method uses a simpler device to create the light pattern, making it faster, cheaper, and easier for future scientific discoveries.
Researchers have developed a novel cell culturing technique that reveals the hidden biomechanics of breast cancer — the end goal, “radical improvement” in the laborious process of screening chemotherapeutics.

Using an advanced artificial intelligence tool, researchers at the Icahn School of Medicine at Mount Sinai have identified rare coding variants in 17 genes that shed light on the molecular basis of coronary artery disease (CAD), the leading cause of morbidity and mortality worldwide. The discoveries, detailed in the June 11 online issue of Nature Genetics, reveal genetic factors impacting heart disease that open new avenues for targeted treatments and personalized approaches to cardiovascular care. The investigators used an in silico, or computer-derived, score for coronary artery disease (ISCAD) that holistically represents CAD, as described in a previous paper by the team in The Lancet. The ISCAD score incorporates hundreds of different clinical features from the electronic health record, including vital signs, laboratory test results, medications, symptoms, and diagnoses. To build the score, they trained machine learning models on the electronic health records of 604,914 individuals
