Anew genetic variant that protects against Alzheimer’s disease has been identified by an international team led by Harvard Medical School investigators at Massachusetts General Hospital and Massachuse...
Unlike women, who are born with all the eggs they’ll ever have, men can continue to produce sperm throughout their adult lives. To do so, they require a constant renewal of spermatogonial stem cells, ...
Anewly described softshell turtle that lived in North Dakota 66.5 million years ago at the end of the Cretaceous Period, just before the end-Cretaceous mass extinction, is one of the earliest known sp...
通过图位克隆鉴定了控制开发花蕾的ob1基因,是位于D13染色体上的MIXTA-like MYB基因,解释了ob2位点的因果变异。运用全基因组转录组分析技术,发现ob突变体中部分MYB基因和细胞壁生物发生、毛状体分化、细胞分裂素信号转导和细胞分裂的相关基因受到抑制,花瓣生长可能因此受到抑制。
The delicate stalk and pretty white flowers of Triantha occidentalis may seem like the perfect place to perch if you're an insect, but get trapped in its sticky hairs and it will suck the nutrients fr...
Biologists believe they are one step closer to a long-held goal of making a cheap, widely available plant source for energy and fuel. One of the next big weapons in the battle against climate change m...
A fertilized human egg develops into multiple tissues, organs and about 200 distinct cell types. Each cell type has the same genes, but they are expressed differently during development and in mature ...
A study led by UC Santa Cruz researchers has found that drought dramatically increases the severity of West Nile virus epidemics in the United States, although populations affected by large outbreaks ...
Using cryo-electron microscopy, an international group of scientists has solved the atomic structure of the human aichi virus (AiV), a rather unusual but poorly characterized picornavirus that is very...
As one of the most abundant organic compounds on the planet, methanol occurs naturally in the environment as plants release it as they grow and decompose. It is also found in the ocean, where it is a ...
How nature makes its biominerals — things like teeth, bone and seashells — is a playbook scientists have long been trying to read.Among the most intriguing biominerals is nacre, or mother-of-pearl — t...
Evolutionary change in a gene resurrected in the lab from the extinct woolly mammoth altered the gene's temperature sensitivity and likely was part of a suite of adaptations that allowed the mammoth t...
Adrian Marchetti and his team of oceanographers in UNC-Chapel Hill’s College of Arts and Sciences have identified — for the first time — that a protein called proteorhodopsin could allow a major group...
Thoroughbred, a relatively recent horse breed, is best known for its use in horse racing. Although myostatin (MSTN) variants have been reported to be highly associated with horse racing performance, t...
