Study of gigantism in whales provides clues to genomic mechanism involved in tumor suppression
The functioning of certain regions of a few genes in cetaceans (whales, porpoises and dolphins) may explain why the Blue whale (Balaenoptera musculus) can reach lengths of up to 30 meters—almost 10 m more than a bus—while the Bottlenose dolphin (.....»»

AI tools help uncover enzyme mechanisms for lasso peptides
Lasso peptides are natural products made by bacteria. Their unusual lasso shape endows them with remarkable stability, protecting them from extreme conditions. In a new study, published in Nature Chemical Biology, researchers have constructed and tes.....»»
New data science tool greatly speeds up molecular analysis of our environment
A research team led by scientists at the University of California, Riverside, has developed a computational workflow for analyzing large data sets in the field of metabolomics, the study of small molecules found within cells, biofluids, tissues, and.....»»
Study reveals large ocean heat storage efficiency during the last deglaciation
As one of the largest heat reservoirs in the climate system, the global ocean absorbs more than 90% of the excess energy from ongoing anthropogenic warming. In the last century, the greatest warming in the ocean has occurred in the upper 500 m, with.....»»
Researchers identify novel endocytic recycling mechanism with "kiss-and-run" membrane fusion
Endocytosis and recycling control the uptake and retrieval of various materials in eukaryotic cells. Mammalian cells have developed several recycling routes, including the relatively extensively studied "fast" and "slow" tubulovesicular recycling pat.....»»
How a bacterial pathogen that causes dysentery manipulates molecular activity to assure its survival
Virginia Tech researchers have learned how bacteria manipulate molecules to infect the host organism. Daniel Capelluto and his research team have discovered the mechanism by which the bacterial pathogen Shigella flexneri, the causative agent of dysen.....»»

Study shows cholesterol enhances exosome-mediated RNA drug delivery
RNA interference (RNAi) technology has gradually become a cutting-edge technology for treating diseases such as genetic disorders and cancer due to its huge potential in gene expression regulation. However, the efficient delivery and safety of short.....»»
Study shows organonitrates in atmospheric particles vary with altitude
While atmospheric particles directly affect climate (e.g., cloud formation), sampling atmospheric particles aloft is practically challenging. Therefore, a full understanding of how particle composition is linked to environmental function remains limi.....»»
Study reveals gender gap in ecology research
Women working in the field of ecology contribute overproportionately to research output, as shown by a recent study that reveals facets of gender bias in the context of scientific publications that have received little attention until now......»»
Deforestation in the Amazon is driven more by domestic demand than by the export market, finds study
