A passage in the Norse "Sverris Saga," the 800-year-old story of King Sverre Sigurdsson, describes a military raid that occurred in AD 1197, during which a body was thrown into a well at Sverresborg Castle, outside Trondheim in central Norway, likely as an attempt to poison the main water source for the local inhabitants.

For the first time, EPFL researchers have exclusively observed molecules participating in hydrogen bonds in liquid water, measuring electronic and nuclear quantum effects that were previously accessible only via theoretical simulations.

Fine-tuning the reactions that produce hydrogen (H2) for use as a clean fuel is an important endeavor to fight against climate change. Researchers at Tohoku University and the Tokyo University of Science have succeeded in improving the catalytic activity for this reaction. The researchers established a synthesis method that can control the surface structure of small metal particles with a diameter of about 1 nm.

In cooperation with researchers from the China University of Petroleum, the working group of Dr. Werner Nau, Professor of Chemistry at Constructor University, has demonstrated the effectiveness of a new method of intracellular protein transport.

Research from Dr. Giovanni Sena's group in the Department of Life Sciences highlights an intriguing method to help protect plants from pathogen attacks using weak electric fields.

A team of chemists at the University of Cambridge has developed a metal-free way to convert symmetrical diols selectively into one of two mirror-image isomers. In their paper published in the journal Science, the group took advantage of the ability of chiral versions of quinuclidine—which were derived from Cinchona alkaloids—to catalyze the dememorization of meso-diols under a blue light in conjunction with a photocatalyst and extract hydrogen atoms from symmetrical molecules.

A new framework bridges a gap in understanding RNA therapeutics by linking the structure of lipid nanoparticles to immune response. It can help scientists and engineers expand the use of RNA medicines beyond vaccines to other therapeutic applications.

Researchers Tomohito Amano and Shinji Tsuneyuki of the University of Tokyo with Tamio Yamazaki of CURIE (JSR-UTokyo Collaboration Hub) have developed a new machine learning model to predict the dielectric function of materials, rather than calculating from first-principles.

The Attosecond Science group at the Center for Free-Electron Laser Science has developed a novel light source capable of producing extremely short pulses for the investigation of UV-induced molecular dynamics with unprecedented temporal resolution. Scientists from the University of Hamburg and from DESY describe their unique observations in an article published in Nature Communications.

A research team led by Assistant Professor Makoto Miyoshi of the National Astronomical Observatory of Japan (NAOJ) has independently re-analyzed observation data of the supermassive black hole at the center of the Milky Way galaxy obtained and published by the international joint observation project Event Horizon Telescope (EHT). They found that the structure is slightly elongated in the east-west direction.
