Even with federal grants largely restored, scientists say the Trump administration is still preventing those funds from reaching them. The consequences, they say, are already becoming clear.

Why mammals cannot regenerate limbs like amphibians do presents a long-standing puzzle in biology. To uncover the underlying differences, we compared amputation responses of embryonic mouse (Mus musculus) and Xenopus laevis tadpole limbs. Lowering ...

Nature Ecology & Evolution - This Review discusses recent advances in the molecular evolution of vertebrate organs, including rates of evolution of organs and cell types, molecular mechanisms...

The molecular, cellular, and functional restoration of the axolotl thymus after de novo regeneration is described.

Iain Cheeseman and colleagues reveal the underappreciated role of single genes producing multiple proteins in atypical presentations of rare disease, and present case studies of affected patients thro...

To study pathways that lead to aneuploidy during aging, the authors provide a system that enables cohesion protein depletion in mouse oocytes, mimicking effects that occur during aging. They uncover a...

We discover and study reverse transcriptases

The Department of Human Evolutionary Biology at Harvard University invites applications for a Postdoctoral Fellow in the Evolutionary and Developmental Genetics Laboratory of Dr. Terence D. Capellini....

Nature Reviews Neuroscience - Recent studies have shed further light on the evolutionary origins of chemical synapses, In this Review, Colgren and Burkhardt explore how ancient proteins were...

During menstruation, an inner layer of the endometrium is selectively shed, while an outer, progenitor-containing layer is preserved to support repeated regeneration. Progress in understanding this co...

Understanding how life is adapting to urban environments represents an important challenge in evolutionary biology. In this work, we investigate a widely cited example of urban adaptation, Culex pipie...

The villous syncytiotrophoblast in humans is the interface between maternal blood and the placenta and its functions are essential for a successful pregnancy. The syncytium can be damaged in vivo foca...
