Animals that have been used for research by the Food and Drug Administration (FDA) will now be available for adoption. 



Under the updated policy, which was adopted in November but not reported by the agency until now, healthy dogs, cats, rabbits, guinea pigs and some farm animals are now permitted to be transferred to shelters and sanctuaries after they’ve been used for lab experiments. 
Previously, the animals were euthanised after being involved in experiments. 
According to the new guidelines, first reported by The Hill, the policy applies to animals that have “completed a research study and have no apparent health or behaviour concerns”.
The FDA’s first initiative to retire animals used in lab experiments occurred in January 2018, when the agency retired 26 squirrel monkeys that had been involved in a nicotine study,” the outlet reported. 
Under the Animal Freedom from Testing, Experiments and Research (AFTER) Act, which was introduced in 2019 by Senator Susan Collins, federal laborat…

Pregnancy might hold the key to understanding how cancer metastasizes in various mammals -- including humans, according to researchers. Kshitiz, assistant professor in the department of biomedical engineering -- a shared department between the School of Dental Medicine, School of Medicine, and School of Engineering -- and Gunter Wagner and Andre Levchenko at Yale University used evolutionary biology to draw the connection in the Nature Ecology & Evolution journal.
Looking at cells from endometrium of various species, Scientists found that in order to resist invasion of the placenta, certain species have evolved over time to make their stromal cells -- the connective tissue cells in an organ -- highly resistant to any invasion. 
In contrast, humans are particularly vulnerable to cancer metastasis owing to their highly invasive placentation during pregnancy. This study identified the cause linking the curious similarity between pregnancy and cancer invasion across various mammals.
