Scientists at NYU Abu Dhabi have created an AI model that forecasts solar wind speeds up to four days in advance with far greater accuracy than existing methods. The breakthrough, published in The Astrophysical Journal Supplement Series, could protect satellites, navigation systems, and power grids from harmful space weather events.
Scientists created the most accurate three-dimensional map of star-formation regions in our Milky Way galaxy, based on data from the European Space Agency’s Gaia space telescope. This map will teach us more about these obscure cloudy areas, and the hot young stars that shape them.
Xinting Yu, assistant professor in the Department of Physics and Astronomy at The University of Texas at San Antonio, is one of two recipients of the 2025 Harold C. Urey Prize.
The national award from the American Astronomical Society’s Division for Planetary Sciences recognizes early-career scientists shaping the future of space research.
Yu was honored for her research in planetary and exoplanetary science — the study of planets in our solar system and beyond. Her work focuses on how planetary surfaces and atmospheres interact and evolve.
The first ab initio calculation of the rarest electromagnetic transition in atomic nuclei, the hexacontatetrapole E6 transition in 53Fe, has been performed. Using the valence-space in-medium similarity renormalization group (VS-IMSRG) methods with realistic nuclear force and bare nucleon charges, the study has successfully explained both the excitation energies and electromagnetic decay rates of the unique T1/2 = 2.54-minutes Jπ = 19/2- isomer at 3.0 MeV. This study provides unprecedented insights into nuclear structure under extreme conditions and validates ab initio approaches for describing the high-multipole electromagnetic transitions in atomic nuclei. The research demonstrates that the formation of 19/2- isomer arises from the pure 0f7/2 orbital configuration.
Pharmaceutical scientists at the National University of Singapore (NUS) have developed a method that can measure the kinetic efficiency of an enzyme against more than 200,000 potential peptide substrates in a single experiment.
Characterising the interactions between enzymes and their substrates is a fundamental task in biochemistry, essential for engineering new biocatalysts, understanding disease mechanisms, and designing therapeutics. While existing techniques can study many enzymatic reactions in parallel, scaling such methods to comprehensively analyse an enzyme's preferences across a vast space of possible substrates remains a practical challenge.
Assistant Professor Alexander Vinogradov from the NUS Department of Pharmacy and Pharmaceutical Sciences has developed a strategy called DOMEK (mRNA-display-based one-shot measurement of enzymatic kinetics) that addresses this need.
