Heatmaps of historical (1970–1999) and predicted (2070–2098) changes in Shannon’s diversity index according to the nine studied elevation ranges. Credit: Geophysical Research Letters (2024). DOI: 10.1029/2024GL109483 As climate change advances, its impacts are not universally equal, with temperature rising differently by latitude and elevation. Climate heterogeneity is the study of this diversity in Earth’s climate … Read more

An Indian rhinoceros wades through flood water in Assam state on June 20. Devastating floods in India’s northeast that have killed scores of people also swamped a national park, drowning six threatened rhinos and other wildlife, government officials said Tuesday. Floods have begun to ease, Assam state Chief Minister Himanta Biswa Sarma said in a … Read more

Credit: Opto-Electronic Advances (2024). DOI: 10.29026/oea.2024.240029 A new study in Opto-Electronic Advances discusses super-resolution machining of single crystalline sapphire by GHz burst mode femtosecond laser-induced plasma assisted ablation. GHz burst-mode femtosecond (fs) laser, which emits a series of pulse trains (burst pulse) with extremely short intervals of several hundred ps, offers distinct characteristics in materials … Read more

CURIE will investigate where solar radio waves originate in coronal mass ejections, like this one seen in 304- and 171-angstrom wavelengths by NASA’s Solar Dynamics Observatory. Credit: NASA/Goddard Space Flight Center NASA’s CubeSat Radio Interferometry Experiment, or CURIE, is scheduled to launch July 9, 2024, to investigate the unresolved origins of radio waves coming from … Read more

Credit: Unsplash/CC0 Public Domain Coral reefs, those vibrant underwater cities, stand on the precipice of collapse. While rising ocean temperatures and coral bleaching grab headlines, a new essay in Current Biology reveals a hidden layer of complexity in this fight for survival: the often-overlooked roles of the reefs’ smallest inhabitants. Scientists have long understood the … Read more

An artificial photoenzymatic cascade was built through combining the photocatalytic H2O2 production by COF-TfpBpy with the H2O2-dependent enzymatic activity of P450 peroxygenases, achieving efficient sacrificial reagent free synthesis of 1-alkenes and hydroxyl fatty acids from naturally abundant fatty acids with only water, air and visible light.
