All living things have a fleet of tiny copy machines that turn instructions from DNA into RNA molecules responsible for helping build proteins that keep organisms alive. One of those nanoscale machines, called eukaryotic ...
Neanderthals are largely associated with colder climates across Eurasia. But researchers know that both Homo sapiens and Neanderthals moved through nearby Southwest Asia between about 100,000 and 50,000 years ago, and Arabia ...
100 million years ago, long before human intervention, ancestors of grasses, including wheat, rice and maize, developed "bypasses" in chemical pathways used to create two critical compounds: lignin and starch. These more ...
Nearly every cell in the human body contains essentially the same genetic information, yet different cells activate different genes. For regulatory proteins to reach these genes, DNA must be accessible. This accessibility ...
It's one of the origins-of-life chicken-or-egg problems: How could RNA have helped give rise to the first cells before there were cells to contain it?
Where they could once hop and amble freely, urbanization is diminishing amphibians' habitats. Yet small-scale water bodies managed by people—such as those found in the gardens of Japan's temples, shrines and schools—remain ...
Rye is not only a hardy and high-yielding crop, but also possesses a valuable gene pool for wheat breeding. An international research team led by the IPK Leibniz Institute has significantly improved the foundations for research ...
Take a walk in London's Trafalgar Square this summer, and people of all body sizes—some tall, some short—will be wilting in the heat: a real mix of sizes.
For more than a decade, anglers on Lake Memphremagog—which straddles the Quebec–Vermont border—have been catching brown bullhead catfish marked with distinctive black lesions.
Scientists studying one of nature's greatest reproductive innovations have discovered how some lizards evolved from laying eggs to giving birth to live young. The new research is the first to reveal the evolutionary process ...
