Evolutionary insights into shape-shifting proteins
Over millions of years a protein that now folds into two stable structures likely favored first one configuration, then the other, before settling on both.
Sturdy nanoribbons are a cross between a soap bubble and a bulletproof vest
A new strategy for molecular design takes self-assembled materials where they’ve never gone before.
Topological phases emerge in an ecological model
An exotic phenomenon in condensed-matter systems illuminates the behavior of a one-dimensional model akin to the game rock-paper-scissors.

Stressed? Depressed? You are not alone
Many physicists find that establishing work–life balance is crucial to battling the COVID-related stresses of isolation, low productivity, and despondency.
The undermining of science is Trump’s legacy
The past four years saw interference in the scientific process, inaction on climate change, and a weakened federal science workforce. Artificial intelligence and quantum information science benefited.

Quantum firmware and the quantum computing stack
Integrated quantum-control protocols could bridge the gap between abstract algorithms and the physical manipulation of imperfect hardware.
A quantum leap in security
One-photon and two-photon interferences have recently led researchers to develop new classes of quantum cryptographic protocols.
The three physicists
Since 1951, the Prize of the Three Physicists has been awarded by the École Normale Supérieure in honor of Henri Abraham, Eugène Bloch, and Georges Bruhat—successive directors of the university’s physics laboratory. These are their stories.
