Why we age

open access: yesBiological Reviews, EarlyView.
ABSTRACT Three categories of explanations exist for why we age: mechanistic theories, which omit reference to evolutionary forces; weakening force of selection theories, which posit that barriers exist that prevent evolutionary forces from optimising fitness in ageing; and optimisation theories, which posit that evolutionary forces actually select for ...

The flexible, the stereotyped and the in‐between: putting together the combinatory tool use origins hypothesis

open access: yesBiological Reviews, EarlyView.
ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated

Harnessing Carbon‐Containing Materials for Next‐Generation High‐Temperature Electromagnetic Wave Absorbers

open access: yesCarbon Energy, EarlyView.
Traditional carbon materials show limited high‐temperature oxidation resistance, which becomes pronounced above 673 K and significantly restricts their practical applicability. To address this challenge, enhancing polarization loss and leveraging its negative temperature dependence to offset the temperature‐induced increase in conductance loss are ...
