Biological polymers often face a trade-off between stiffness, strength, and extensibility: Materials that are strong and stiff tend to be brittle, while those that are elastic and extensible usually ...

There’s a small, but fierce, jawbone in Argentina’s national natural science museum in Buenos Aires. It’s 6 inches long and studded with backward-curving fangs that would have hooked into flesh to rip ...

Assessing the ergodicity of graphene liquid cell electron microscope measurements, we report that loop states of circular DNA interconvert reversibly and that loop numbers follow the Boltzmann ...

Optical linear and nonlinear spectroscopy is the preferred method for studying the interaction between a solute molecule and its surrounding solvent in liquids because photons are minimally intrusive ...

In the spring of 2022, the Calf Canyon/Hermit’s Creek fire burned over 300,000 acres in New Mexico (1), including terrain near the Rio Gallinas School for Ecology and the Arts in Las Vegas, New Mexico ...

For a number of years, I have argued that we are now, thanks to the effects of human-caused warming, experiencing a new class of monster storms—”category 6” hurricanes. That is to say, we are ...

Computational modeling has become a valuable tool for science and policy, but community standards to share model details have not kept pace. For research to be replicated, evaluated, and improved, ...

Open in Viewer RoBMA PSMA model-averaged posterior mean effect size estimates with 95% credible intervals and Bayes factors for the absence of the effect for the combined sample or split by either the ...

Contributed by Haïm Brezis, December 31, 2020 (sent for review December 8, 2020; reviewed by Lawrence C. Evans, Alessio Figalli, and Fang-Hua Lin) ...

A number of trends in national and international politics greatly affect our capacity to achieve the cooperation that will be necessary to address the challenges facing society over the coming decades ...

There is now an intensifying international effort to develop robust propulsion systems for hypersonic and supersonic flight. Such a system would allow flight through our atmosphere at very high speeds ...

The half-inch-long corn rootworm larva packs a surprising punch. It feasts on the root system of corn before pupating into a black and yellow beetle that does further damage to the plant’s leaves.
