Time in a bottle: Scientists watch evolution unfold

A 21-year Michigan State University experiment that distills the essence of evolution in laboratory flasks not only demonstrates natural selection at work, but could lead to biotechnology and medical research advances, researchers ...

Yeast missing sex genes undergo unexpected sexual reproduction

An emerging form of the pathogenic yeast Candida is able to complete a full sexual cycle in a test tube, even though it's missing the genes for reproduction. And it may also do so while infecting us, according to Duke University ...

Engineers uncover new mechanism for gene transfer

If you still remember that "Dear King Phillip Came Over For Good Spaghetti," you'll likely also recall the corresponding taxonomic ranks of biology: domain, kingdom, phylum, class, order, family, genus and species. The domains ...

A bacterial toolkit for colonizing plants

Using a novel experimental approach, Max Planck researchers have discovered a core set of genes required by commensal bacteria to colonize their plant hosts. The findings published in Nature Communications may have broad ...

Researchers compile world's first 'atlas' of airborne microbes

Bacteria are truly abundant across the Earth's surface, from the soil to the oceans. The microbial population of the air that surrounds us is comparatively unknown, but a research expedition led by PolyU scientists is about ...

How maize makes an antibiotic cocktail

Maize (Zea mays) produces a plethora of antibiotics called zealexins. Even though scientists have identified at least 15 zealexins, they suspect there are even more to find. Zealexins are produced in every corn variety and ...
