A clearer understanding of the risk of permafrost thawing in Alaska
Cost estimates of infrastructure damage up to mid- or late-century caused by predicted warming and thawing permafrost forecasts compared to annual average climate and weather disaster price tags. Credit: Communications Earth & Environment (2025). doi:10.1038/s43247-025-02191-7 In the Arctic, permafrost plays an important role in building infrastructure. However, when the area gets warmer and the permafrost is thawed, the infrastructure is…

Enhanced Raman microscopy enables clearer chemical imaging of cryofixed samples
Raman image of snap-frozen HeLa cells with high signal-to-noise ratio and wide field of view. Image acquisition time was 10 hours. The distribution of Raman signals from cytochromes (750 cm-1), lipids (2850 cm-1), and proteins (2920 cm-1) are shown in green, red, and blue, respectively. Credit: Science Advances (2024). DOI: 10.1126/sciadv.adn0110 Understanding the behavior of the molecules and cells that…

Improved spin-density correlation simulations give researchers clearer insight into neutron stars
Neutrinos travel through a gas of neutrons and are sensitive to the correlation between the spin and density of the neutronic material. These correlations determine how much energy is transferred from the neutrino to the neutron. Credit: Dean Lee When a star dies in a supernova, its remains can become a neutron star. Inside a neutron star, protons and electrons…
