Small cell lung cancer (SCLC) is an aggressive malignancy with limited treatment options and poor prognosis. Understanding the molecular drivers of SCLC is essential for developing effective therapies. This study identified FAK splicing variants as a novel feature of SCLC that promote tumor progression and confer therapy resistance. Targeting these variants sensitized SCLC cells to treatment, revealing a promising therapeutic vulnerability. These findings provide new insights into SCLC biology and suggest potential therapeutic strategies for this difficult-to-treat cancer.

Glycomics, the comprehensive study of glycans and glycoconjugates, has emerged as a powerful tool for disease biomarker discovery. Changes in glycosylation patterns accompany many pathological processes, reflecting alterations in cellular metabolism and function. This review presents insights from cohort studies that have linked specific glycan signatures to disease risk, progression, and outcomes. We discuss the potential of glycomics for precision medicine and early disease detection. The integration of glycomics with other omics approaches promises to enhance our understanding of disease mechanisms and improve diagnostic capabilities.

Chronic kidney disease and end-stage renal disease (ESRD) represent significant global health burdens. Genetic factors contribute substantially to ESRD susceptibility, yet much of the heritability remains unexplained. This X chromosome-wide association study (XWAS) identified novel loci on the X chromosome associated with ESRD risk. Our findings expand the genetic architecture of kidney disease and may inform future therapeutic targets. The study highlights the importance of including the X chromosome in genetic association studies, as it harbors variants that may contribute to disease susceptibility.

Shortly after transcription initiation, RNA polymerase II (Pol II) pauses near gene promoters before entering productive elongation, representing a key regulatory step in gene expression. In the recent study published in Science Bulletin, researchers from the Institute of Genetics and Developmental Biology, Chinese Academy of Sciences, combined acute protein degradation with genome-wide analyses to capture the immediate functions of the transcription factor GABPA in mouse embryonic stem cells. They discovered that, independently of its canonical partner GABPB, GABPA recruits the Integrator complex to promoter regions, thereby promoting productive transcription elongation. The study uncovers an unexpected role for a classical transcription factor and reveals how the Integrator complex is selectively recruited to specific genes.

Dr Lana Ciarniello is an independent wildlife research biologist and co-chair of the IUCN SSC Bear Specialist Group's human-bear conflict expert team. She is currently the principal investigator for the Orphaned Grizzly Bear Rewilding Project, which is the only rehabilitation and research program for grizzly bears in North America. In a new Frontiers in Conservation Science article, Ciarniello explores why current attempts to rehabilitate orphaned grizzly bears to the wilderness might be backfiring. Based on her findings from five years of monitoring rehabilitated grizzly cubs, she poses the question of whether rehabilitation programs in their current form are an effective conservation tool or sympathetic management.

How dinosaurs digested food has long remained a mystery because soft tissues such as stomachs and intestines are rarely preserved in the fossil record. In a new study, researchers analyzed the shapes and wear patterns of gastroliths—stones preserved in the abdominal cavities of dinosaurs—and compared them with those of living birds and crocodilians. The results suggest that rounded, heavily worn gastroliths indicate the presence of muscular stomachs used to grind food, while angular gastroliths are associated with less muscular stomachs. Applying this framework to dinosaurs, the team found evidence that different groups evolved distinct digestive strategies. Some toothless theropods likely processed plant material using bird-like muscular stomachs, whereas herbivorous dinosaurs such as sauropods and ornithischians may have relied more on their teeth and prolonged intestinal fermentation than on gastrolith-assisted grinding. The study presents a new hypothesis for the evolution of dinosaur digestive systems and provides a framework for reconstructing feeding biology by integrating gastrolith evidence with other dietary indicators.
