Researchers find cryptic genetic element in the human gut that could serve as a sensitive biomarker

A component of the human intestinal flora that has been little studied to date is the focus of a new study from Germany. Plasmids are small extrachromosomal genetic elements that frequently occur in bacterial cells and can ...

New study finds potential targets at chromosome ends for degenerative disease prevention

We depend on our cells being able to divide and multiply, whether it's to replace sunburnt skin or replenish our blood supply and recover from injury. Chromosomes, which carry all of our genetic instructions, must be copied ...

Scientists discover first nitrogen-fixing organelle

Modern biology textbooks assert that only bacteria can take nitrogen from the atmosphere and convert it into a form that is usable for life. Plants that fix nitrogen, such as legumes, do so by harboring symbiotic bacteria ...

Biologists reveal how gyrase resolves DNA entanglements

Picture in your mind a traditional "landline" telephone with a coiled cord connecting the handset to the phone. The coiled telephone cord and the DNA double helix that stores the genetic material in every cell in the body ...

Flowers may be more ancient than dinosaurs, but scientists can't agree on when they evolved

Flowers may look delicate—but flowering plants, what scientists call angiosperms, are one of the most successful evolutionary organisms on the planet. Including more than 350,000 known species, they dominate the ecological ...

Fossilized dinosaur eggshells can preserve amino acids, the building blocks of proteins, over millions of years

As a scientist, lab work can sometimes get monotonous. But in 2017, while a Ph.D. student of paleobiology at the University of Bristol in the U.K., I heard a gleeful exclamation from across the room. Kirsty Penkman, head ...
