If we could rewind the tape of species evolution around the world and play it forward over hundreds of millions of years to the present day, we would see biodiversity clustering around regions of tect...
中国科学院化学研究所专利:一类用于DNA原位杂交荧光检测(FISH)技术的生物试剂及其制备和应用
2023年3月17日,中国科学院深圳先进技术研究院合成微生物组学研究中心、深圳合成生物学创新研究院戴磊课题组在Nature Communications上发表了基于成像的空间微生物组最新研究成果,题为"Spatial profiling of microbial communities by sequential FISH with error-robust encoding"。该团队发展了一种可...
A team of U.S. National Science Foundation-funded scientists has identified at least 11 species of fish suspected to have land-walking abilities.The findings are based on CT scans and a new evolu...
Using the same mechanism, several species of fish have adapted to harsh environments, calling into question the idea of evolutionary chance, according to a National Science Foundation-funded stud...
对杂交三倍体泥鳅(4n♀×2n♂)的胚胎染色体进行了C带及染色体荧光原位杂交(FISH)分析,首次探讨了杂交三倍体泥鳅C带特征,为准确鉴别染色体提供依据,研究了核糖体5.8S+28S rDNA在杂交三倍体泥鳅胚胎中期染色体上的数目和位置。C带结果表明,杂交三倍体泥鳅的染色体C带包括臂端C带和着丝粒C带,没有发现臂间C带。M染色体只有1号染色体既有臂端C带又有着丝粒C带,但臂端C带均比着丝粒C带大,...
According to the Guinness World Records, the longest any person has held a continuous vocal note is just shy of two minutes. That’s quite an achievement. Compared to the Pacific midshipman fish, howe...
An unspoken frustration for evolutionary biologists over the past 100 years, says Craig Albertson at the University of Massachusetts Amherst, is that genetics can only account for a small percentage o...
In 1988, Irish singer and songwriter Enya released a lead single titled “Orinoco Flow” from her second studio album, which went on to become an international hit, earn a Grammy Award nomination, and h...
Sex-changing fish exhibit differences in androgen receptor (AR) expression in muscles that are highly sensitive to androgens (male sex hormones) and essential for male courtship behavior, according to...
The sensory system in fish fins evolves in parallel to fin shape and mechanics, and is specifically tuned to work with the fish’s swimming behavior, according to new research from the University of Ch...
In a new study, researchers at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science examined how the interaction of two genomes in animal cells—the mitochondrial and nuclea...
Scientists once thought that being part of a community would protect animal populations from infectious disease outbreaks, but now they've learned otherwise, according to a study published this week i...
While a dominant male fish from northern Mexico mates with a female, a small fella bides his time in the offing. Suddenly, the little guy darts in ahead of Mr. Big and plants his seeds on freshly laid...
Background: Meat and fish intakes have been associated with various chronic diseases. The use of specific biomarkers may help to assess meat and fish intake and improve subject classification accordin...
