A Nagoya University team has overcome one of the key limitations of X-ray technology by making the mirror using only a single-crystal piezoelectric thin wafer instead of the usual two-part structure. Using this technique, they changed X-ray beam size by more than 3,400 times. This improved dynamic range massively improves both imaging and analysis, improving the efficiency of advanced techniques and massively enhancing workflows.
A new study has revealed for the first time that zooplankton migration contributes significantly to carbon sequestration in the Southern Ocean—a process overlooked in climate models.
To elucidate the molecular mechanisms underlying cellular response to graded hypoxia, Wei Wang's team at Nanjing University, developed a quantitative regulatory network model of HIF-1α. By integrating dynamic simulations, bifurcation analysis, mechanistic prediction, and functional validation, the study systematically revealed that HIF-1α activation is a progressive process. This activation is primarily governed by the sequential inactivation of two classes of hydroxylases—prolyl hydroxylases (PHDs) and factor inhibiting HIF (FIH)—which orchestrate tiered cellular adaptive responses.
Just the word “quantum” can make even seasoned science teachers break into a sweat. But a national pilot program led by The University of Texas at Arlington is helping take the mystery out of the subject for students and educators alike. This week, 50 high school students and science teachers gathered at Arlington Martin High School to dive into the topic through Quantum for All, a program launched by Karen Jo Matsler, a professor of practice and master teacher in UT Arlington’s UTeach program.
