Blood sampling in rodents is common practice in scientific studies. Some of the refined methods widely used are the puncture of the saphenous vein or tail vein, or even tail docking. The handling ...

Mice are the most commonly used laboratory animal, yet there are limited studies which investigate the effects of repeated handling on their welfare and scientific outcomes. Furthermore, simple ...

Microplastics in the bloodstream may cause blockages the brain and affect our brain functioning and behavior, according to recent research. Environmental biologists tested the effects of microplastics ...

With microplastics now permeating our food and our bodies, researchers are keen to assess the potential damage these tiny fragments could be doing. A new study shows how plastics may lead to dangerous ...

In a study straight out of science fiction, scientists have increased the lifespans of old mice by 10 percent by fusing them and their bloodstreams with younger animals. For the first time, the team ...

In what sounds like dystopian sci-fi, researchers have recently shown that infusions of youthful blood can improve the health of older people. A new study has found that an existing arthritis drug can ...

When cells are exposed to stress and damage, cellular senescence occurs. This phenomenon increases with aging. Senescent cells (SnCs) attain permanent growth arrest and exhibit senescence-associated ...

Infusions of youthful blood led older mice to live 6 to 9 percent longer, a new study found. By Carl Zimmer A team of scientists has extended the lives of old mice by connecting their blood vessels to ...
