Animal models have long shaped how biomedical research is conducted. They have influenced how diseases are studied, how risks are assessed, and how potential treatments move from early discovery ...

Our body's "blood factory" consists of specialized tissue made up of bone cells, blood vessels, nerves and other cell types. Now, researchers have succeeded for the first time in recreating this ...

Scientists have developed a new surgical technique for implanting multiple tissue grafts in the eye's retina. The findings in animals may help advance treatment options for dry age-related macular ...

New organ-on-a-chip recreates the cervix’s microbiome and immune system, revealing how bacteria shape STI infection risk.

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

Using mathematical analysis of patterns of human and animal cell behavior, scientists say they have developed a computer program that mimics the behavior of such cells in any part of the body. Led by ...

Every year, more than 100 million animals are used globally in biomedical research, yet over 90% of drugs that appear effective in animal trials fail during human clinical testing. 1 This staggering ...

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 ...
