🚨PREPRINT ALERT How different are males and females? In physiology we mostly treat that as a fixed property of a species, something to control for. In mice, we found it is not fixed at all. It depends on what the animal ate while growing up.

Juvenile protein restriction compresses sexual dimorphism in mice

Sexual dimorphism is canonically understood as a fixed adult trait, scaled by gonadal hormones at puberty, but whether its magnitude is shaped earlier in life by juvenile nutrition during the post-wea...

🔴A few years ago, we reported vinyl copolymers with faster hydrolytic degradation than aliphatic polyesters, and tunable UCST, synthesized by rROP of acrylamide and cyclic ketene acetals (CKA) doi.org/10.1038/s414... However, this interesting step forward in the field of rROP was left unexplained⁉️

Vinyl copolymers with faster hydrolytic degradation than aliphatic polyesters and tunable upper critical solution temperatures - Nature Communications

The non-degradability of vinyl polymers has long limited their use in biomedical applications. In this article, the authors demonstrate a system based on acrylamide and cyclic ketene acetals to obtain...

Two extraordinary charts from today’s PISA test results: 1) School test scores continue to collapse internationally, underscoring how this is no longer a Covid effect but sustained decline. Those falls in reading and maths are equivalent to about two years of lost schooling.
