Why do whales and elephants have much lower rates of cancer than expected?

risk are those with a higher presence of cooperative and caring habits, while the opposite is found....:"

Coevolution of cooperative lifestyles and reduced cancer prevalence in mammals
While cooperative mammals evolve reducing cancer prevalence, oncogenes can be maintained by selection in competitive species.

The intelligence of slime mold is that of its materials

All of Physarum's intelligent behaviors can be explained by physics, as in non-living materials (e.g., water following the path of least resistance), and do not require a representation of the problem.

Was happy to write a commentary for this very cool opportunistic study of long-term neural effects of partner loss in coyotes (which are the rare sexually monogamous species). Naturalistic studies of non-model species are a great complement to lab models.

⚠️ House Republicans’ new FY26 bill would slash EPA & Fish & Wildlife funding and gut the Endangered Species Act, stripping protections from gray wolves, grizzlies, wolverines & more.

This is a direct attack on wildlife, ecosystems, and public health. We must speak out.
