Clues to bee health found in their gut microbiome

The local environment plays a pivotal role in the health and diversity of the gut microbiome of wild bees which could help detect invisible stressors and early indicators of potential threats, say York University scientists ...

Retro technique advances modern bacterial engineering for bioenergy

Oak Ridge National Laboratory scientists had a problem mapping the genomes of bacteria to better understand the origins of their physical traits and improve their function for bioenergy production. The method they had successfully ...

Competition among worm sperm speeds up evolution

From elaborate dances to stunning plumage displays to dramatic head-butting, male animals have an array of ways to distinguish themselves from competitors while wooing a potential mate. But it's not their only chance to prove ...

Gene editing now possible in ticks

Researchers have successfully used CRISPR-Cas9 to edit the genomes of the black-legged tick. To accomplish this feat, they developed an embryo injection protocol that overcame a major barrier in the field. The work appears ...

Male-biased protein expression discovered in fruit flies

Fruit flies (Drosophila) are important model organisms for biological research. Molecular tools exist that can turn on (or induce) gene expression in fruit flies, allowing researchers to learn more about the functions of ...

Breeding beetle-resistant potatoes

Potatoes are the most consumed vegetable in the United States. According to the USDA, US farmers grew more than 42 billion lbs. of potatoes in 2019. That's 128 lbs. of potatoes per person.

Just 7% of our DNA is unique to modern humans, study shows

What makes humans unique? Scientists have taken another step toward solving an enduring mystery with a new tool that may allow for more precise comparisons between the DNA of modern humans and that of our extinct ancestors.

Researchers improve efficiency and accessibility of CRISPR

One of the most powerful tools available to biologists these days is CRISPR-Cas9, a combination of specialized RNA and protein that acts like a molecular scalpel, allowing researchers to precisely slice and dice pieces of ...
