A study reconstructs rainfall patterns during the extreme warming during the early Paleogene Period, 66 to 48 millions years ago. Conducted by University of Utah atmospheric scientists and Colorado School of Mines geologists, the research examined “proxies” in the geologic record and drew conclusions that suggest rainfall becomes more intense, but more irregular when Earth gets hot.

A record of repeated retreat of the West Antarctic Ice Sheet during the past warm climates has been identified by IODP Exp379 Scientists. By analyzing deep-sea sediments from the Amundsen Sea and tracing their geochemical signatures, the study shows that the ice sheet retreated far inland at least five times during the warm Pliocene Epoch. The findings highlight the ice sheet’s sensitivity to warming and its potential to drive future sea-level rise.

An multi-institutional group of researchers have outlined changes to the research and peer review process that have the potential to increase the reliability of experimental results: sharing more data and openly discussing alternative explanations. 

Scientists at the University of Connecticut have developed a handheld ‘pocket microscope’ that directly visualizes DNA and proteins in living cells without stains or labels. The system uses deep-ultraviolet light to map molecules with femtogram sensitivity, achieving 308-nanometer resolution across centimeter-wide areas. The device enables instant pathology diagnosis, identifies cancer cells, and maps brain neurons -- all while preserving samples’ natural state. This technology could transform medical diagnostics, from operating rooms to space missions.

Researchers at the Department of Energy’s Oak Ridge National Laboratory have developed an innovative energy storage system design that introduces a safer, more efficient method for electrical charge transfer. This study advances fundamental understanding of how functional groups impact the mechanical and electrochemical performance of highly charged polyelectrolyte membranes — thin, charged polymer sheets that help control the movement of ions in energy devices.

Solar physicists say they have found a key source of intense gamma rays unleashed when Earth’s nearest star produces its most violent eruptions.

In findings published in Nature Astronomy, scientists at NJIT’s Center for Solar-Terrestrial Research (NJIT-CSTR) have pinpointed a previously unknown class of high-energy particles in the Sun’s upper atmosphere responsible for generating the long-puzzling radiation signals observed during major solar flare events for decades.
