Can brain tissue be stored without freezing? In a new PNAS Science Sessions episode, researchers explore vitrification—a glass-like preservation method that maintained key structures and functions in mouse brain tissue after rewarming. Listen now: https://ow.ly/O9fH50Z9lc4
2024 broke global mean surface temperature records, but was the heat inexplicable, as some have asserted? A study finds that the 2024 record was consistent with standard climate model predictions, especially given that it was an El Niño year. In PNAS: https://ow.ly/qZEX50Z8VVS
The extreme conditions of the 1945 Trinity nuclear test created trinitite, a silicate glass containing rare metallic phases. A sample of red trinitite was found to contain a silicon-rich cubic clathrate within a copper-rich metal droplet. [DS1.1]In PNAS: https://ow.ly/w43u50Z9thZ
Machine learning helps predict the speed at which rock glaciers move across the Pamir-Karakoram-Kunlun region in High Mountain Asia. Upslope connection to a glacier is a critical factor controlling rock glacier velocities. In PNAS Nexus: https://ow.ly/qlCU50Z9pay
Climate determines the plant characteristics that favor naturalization. In cold or dry regions, successful newcomers must be similar to native plants to survive. In hot and humid regions, distinctiveness makes new plants more competitive. In PNAS: https://ow.ly/Lnla50Z8VyU
Average support for gender equality worldwide has plateaued, in part because of higher population growth in countries where support for women’s rights is low and because of higher fertility among those with less egalitarian views. In PNAS Nexus: https://ow.ly/byTk50Z9pi5

The presence of manganese oxides has been used as a proxy for oxygenation on early Earth, but experiments show that manganese-bearing carbonates can photo-oxidize under the UV wavelengths present on early Earth and Mars—even without oxygen. In PNAS: https://ow.ly/1Kvw50Z8Vfe

People who have overcome adversity often oppose reform to make the goals they achieved less arduous for others. This tendency to “pull up the ladder” stems from a desire to protect the value of a hard-won achievement, according to a study. In PNAS Nexus: https://ow.ly/wAIM50Z8UK4
