POSTECH and Linyi University develop ‘SLY,’ a Probe That Glows Yellow Only in Tumor Cells.

A research team combined metabolomic and transcriptomic analyses to uncover how brain chemistry regulates aggressive behavior.

Gut bacteria are known to be a key factor in many health-related concerns. However, the number and variety of them is vast, as are the ways in which they interact with the body’s chemistry and each other. For the first time, researchers from the University of Tokyo used a special kind of artificial intelligence called a Bayesian neural network to probe a dataset on gut bacteria in order to find relationships that current analytical tools could not reliably identify.

Pretrained jet foundation models can successfully be utilized on a new dataset and on a new set of tasks: the multi-task hadronically decaying tau reconstruction problem.

This study investigates tunneling spectroscopy in Ti/ LaAlO3/KTaO3 junctions, revealing potential p-wave superconductivity at the LaAlO3/KTaO3 interface and offering a universal approach to identifying the most sought-after superconducting states.

In a study published in National Science Review, researchers present multiple lines of observational and modeling evidence for a ~4% decline in global atmospheric oxidation capacity in 2020, reflected by a drop in hydroxyl radical (OH) concentrations. Using satellite-based carbon monoxide data, as well as methane and methyl chloroform observations, the study reveals that this OH reduction occurred in both hemispheres—approximately 2.4% in the Northern Hemisphere and 5.7% in the Southern Hemisphere—driven by distinct mechanisms. In the Northern Hemisphere, reduced NO_x emissions due to COVID-19 lockdowns led to lower OH and tropospheric ozone levels, while in the Southern Hemisphere, massive emissions of reactive carbon from unprecedented Australian wildfires caused OH depletion but tropospheric ozone increases. This contrast in tropospheric ozone anomalies is further corroborated by satellite data. The findings help explain one of the record-breaking rises in atmospheric methane in 2020 and underscore the critical role of both natural and anthropogenic factors in shaping Earth’s atmospheric chemistry and global methane budget.
