For a long time, we’ve been sold the idea that Genghis Khan, the 13th-century founder of the Mongol Empire, was so phenomenally prolific that one in 200 men alive today carries his exact Y chromosome.

Chromosomes are masters of organization. These long strings of DNA fold down into an ensemble of compact structures that keep needed parts of the genome accessible while tucking away those that aren't ...

Scientific progress depends on results that can be repeated – yet across disciplines, too many experiments fail that test. From medicine to economics, the replication crisis reveals not just flawed ...

Extreme heat in Japan and Australia. Flash floods in Texas and across Europe. Billion-dollar-damaging storms in the Caribbean and Southeast Asia. Weslynne Ashton is a professor of environmental ...

Here’s a quick reality check: ice cream sales go up in summer, and so do drownings. But no one thinks Ben & Jerry's is a silent killer. It’s correlation, not causation. Yet this same logical ...

Human egg cells are often prone to chromosomal errors. As women age, the error rate increases sharply — and can contribute to infertility, pregnancy loss, and ...

The initiation of chromosome replication is exquisitely regulated in both time and location. It has been estimated that there are 200-400 autosomal replication sequence elements (ARSs) in the yeast ...

Neil Hunter, a professor in the Department of Microbiology and Molecular Genetics, has discovered a crucial step in how chromosomes stay connected during the development for egg cells and sperm, ...

A team of Chinese researchers led by Prof. GAO Caixia from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences has developed two new genome editing technologies, ...

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

In a groundbreaking discovery, researchers from Florida Atlantic University's Charles E. Schmidt College of Medicine have identified a never-before-seen mechanism that enables the human ...
