Apart from carrying the information to encode proteins in, RNA molecules can adopt intricate 2D and 3D structures. Specifically, the same RNA molecule can switch between ON and OFF structures, ...

As the Trump administration reshapes biomedicine, it wants to change how scientists test drug safety: animal research.

Animals, from worms and sponges to jellyfish and whales, contain anywhere from a few thousand to tens of trillions of nearly genetically identical cells. Depending on the organism, these cells ...

Scientists test in an animal model a surgical technique to improve cell therapy for dry AMD The technique may enable higher doses and combinations of cell therapies Date: May 26, 2025 Source: NIH ...

When animals defecate, they shed living cells from their intestines, and these can be found on the outside of the dung, says Williams, a professor of fertility and reproductive health.

Researchers have developed a method to extract living cells from feces that they say could help conservationists better understand the genetic diversity of wildlife — and in the long run, could ...

Plants’ Photosynthetic Machinery Functions inside Hamster Cells Transplanted chloroplasts endured two days inside animal cells—and got to work ...

This fluorescence image shows chloroplasts (magenta colored) successfully incorporated into the hamster cells, with other features of the animal cell also highlighted (nuclei in light blue and ...

The biologists took chloroplasts—the cell components responsible for photosynthesis —from red algae and injected them into hamster cells. As a result, the animal cells gained the ability to ...

A Japanese team has developed a technique to insert chloroplasts isolated from algae into animal cells, a feat that could revolutionize sustainable energy and how artificial meat and organs are ...
