The debilitating, chronic loss of joint cartilage known as osteoarthritis causes pain and bone decay for hundreds of millions ...

Researchers have developed a method that lets them genetically modify each cell differently in animals. This allows them to study in a single experiment what used to require many animal experiments.

If you think back to your high school biology classes, chances are you’ll have a rudimentary memory of photosynthesis. The process by which plants absorb light from the sun and use it – along with ...

Prefer Newsweek on Google to see more of our trusted coverage when you search. In a world first that challenges what we thought we knew about biology, scientists have successfully engineered animal ...

Animal cell and molecular biology encompasses the study of eukaryotic cells as the fundamental units of life, focusing on their structure, function, development, and the intricate regulatory ...

Energy-making chloroplasts from algae have been inserted into hamster cells, enabling the cells to photosynthesize light, according to new research in Japan. It was previously thought that combining ...

Chloroplasts, the parts of cells that allow plants and algae to photosynthesize, are thought to have originated more than 1 billion years ago, when photosynthetic cyanobacteria lived symbiotically ...

Experiments on animals (“in vivo” experiments) have long been the norm for learning about human health and disease, because testing on live animals enables researchers to investigate how chemicals, ...

Last November, the UK government announced a bold plan to phase out animal testing in some areas of research. Animal tests for skin irritation are scheduled for elimination this year, and some studies ...
