Stem cell study paves way for manufacturing cultured meat

Scientists have for the first time obtained stem cells from livestock that grow under chemically defined conditions, paving the way for manufacturing cell cultured meat and breeding enhanced livestock.

Mating, tattoos and leaving home: A tale of growing up guppy

Nature is full of big questions that are easy to ask and hard to answer. With some good old-fashioned hard work and help from a humble, gilled vertebrate, though, Michigan State University's Sarah Fitzpatrick and Isabela ...

Researchers call for standards for biological imaging

Stained molecules in the cell nucleus, the inner life of a synaptic cleft, or the surface of a floral leaf: Modern microscopes enable researchers to examine processes that are otherwise invisible and located in tiniest structures ...

Thousands of turtles lay eggs on Nicaraguan coast

Thousands of sea turtles laid their eggs on Nicaragua's coast over the weekend under the watchful eye of the army, which protects the nests from possible predators—including humans.

Montana seeks to end protections for Glacier-area grizzlies

CRISPRing the microbiome is just around the corner

To date, CRISPR enzymes have been used to edit the genomes of one type of cell at a time: They cut, delete or add genes to a specific kind of cell within a tissue or organ, for example, or to one kind of microbe growing in ...

Visualising cell structures in three dimensions in mere minutes

Viral pathogens like the SARS-CoV-2 coronavirus change the interior structure of the cells they infect. These changes occur at the level of individual cell components—the organelles—and can provide information on how ...

Examining the neurotoxin from a black widow

Phobias are often irrational by nature—especially in the case of spiders, as these creatures are usually more afraid of humans than vice-versa. But: some species are a force to be reckoned with—for example, the Latrodectus ...

Tigers ending their days in high-pressure cookers 

More tigers now live in illegal captivity, on so-called "tiger farms," than in the wild. The prominence of these farms is highest in Vietnam, China and Thailand. On the farms, tigers are raised as livestock for the sole purpose ...

Migratory birds have lighter-colored feathers

Migratory birds are specially adapted to find their way over extreme distances that represent remarkable tests of endurance. Now, researchers reporting December 6 in the journal Current Biology have discovered an unexpected ...

Big gaps in quest to sequence genomes of all animals

Efforts to sequence the genomes of the world's animals tend to focus on those that most resemble humans with the work conducted almost entirely in the Global North, according to an analysis led by Washington State University.

How effective are honey bees as pollinators?

Honeybees are celebrated as effective plant pollinators, but just how effective are they? Newly published UC Davis research in the American Journal of Botany yields some surprising results.
