A new engineered gene-editing system, proven in bacteria and showing promise for use in plants, animals and humans, addresses some limitations of current gene-editing tools, with the goal of improving their use in research, ...
Researchers studying a giant tortoise named Jonathan say it's not just good genes but a lack of genetic wear and tear that has kept him going for nearly two centuries.
Understanding changes in North American bat populations is critical to measuring the risk of extinction from emerging threats such as habitat loss, climate change, white-nose syndrome and other disturbances. A study published ...
As waves of humans left Africa tens of thousands of years ago, eventually populating the entire planet, they were joined on their world-conquering ride by the trillions of microorganisms that compose the gut microbiome.
Scientists Henri B. Kagan and Kenso Soai won the Nobel Prize in chemistry Wednesday for untangling mysterious mirror images in molecules, a discovery that has been used to develop countless drugs and transformed modern medicine.
Research into molecules that regulate sleep and appetite or methods for editing genes could be among the contenders for the Nobel Prize in chemistry, to be announced Wednesday, commentators say.
For Dr. Jamaluddin Jompa, the ocean has never been simply a subject of scientific study. He was born in Takalar, a coastal region of South Sulawesi, Indonesia, and his connection with the sea was forged early. Witnessing ...
DNA can be more than just a double helix. When four strands are folded into a compact bundle, they form a G-quadruplex (G4). These bundles form in guanine-rich regions across the genome, including telomeres at the ends of ...
Extreme heat can have a profound impact on wild animals, causing their death in the most extreme cases and leaving less visible marks in others. Understanding the effects of temperature changes on specific species could inform ...
One of the unresolved mysteries about the history of the Americas is when the first people arrived. Despite extensive debate centering on genetic, archaeological and environmental evidence, there is still no consensus or ...
