追踪藻类物种的相互作用,以帮助预测有害藻类的大量繁殖

Harmful algal blooms, sometimes called HABs, occur when algae grow out of control. Algae are photosynthetic organisms that mostly live in water and rely on the sunlight for energy. Because of climate change, the frequency and intensity of harmful algal bl

分析发现“Protura姐妹”假说存在缺陷:重新评估早期六足类系统发育

The early lineages of hexapods (broadly defined insects) have long been debated. Researchers at University of Tsukuba and collaborators critically examined the newly proposed "Protura-sister" phylogenetic hypothesis. This analysis revealed a fun

剪接体:从原子水平研究细胞在制造mRNA时如何避免错误

A complex molecular machine, the spliceosome, ensures that the genetic information from the genome, after being transcribed into mRNA precursors, is correctly assembled into mature mRNA. Splicing is a basic requirement for producing proteins that fulfill

某些种类的须鲸可能会因为歌声太低而无法被听到,从而避免吸引虎鲸

Killer whales are the only natural predator of baleen whales—those that have "baleen" in their mouths to sieve their plankton diet from the water. More solitary than toothed whales, baleen whales face predatory attacks from killer whales, especi

细菌物种研究挑战了结构相似性预测蛋白质行为的假设

A new study published in Biochemistry sheds light on how bacteria regulate their genes, challenging long-held assumptions about protein behavior. The research compares how two bacterial species—Escherichia coli and Mycobacterium tuberculosis—use a signali
