Phys.org / Looped polymers unlock stronger, faster molecular binding through entropy, model suggests

Entropy gets a bad rap. Typically associated with randomness and chaos, it can also correlate with freedom and diversity. Cornell researchers have found that, thanks to the latter qualities, entropy can help bind certain ...

Phys.org / Why gradual environmental change can trigger sudden species collapse and fragmented populations

When species are subjected to changing environments, they can survive in their current location through genetic adaptation. However, this ability is not unlimited. In a study published in PNAS, biomathematician Jitka Polechová ...
