Dashing the dream of ideal ‘invisibility’ cloaks for stress waves

Roman Colosseum (stock image). Roman arenas have survived in many earthquake-prone regions. Did the Romans inadvertently build seismic wave cloaks when they designed colosseums? Some researchers believe they did due to the arenas' resemblance to modern experimental elastodynamic cloaking devices.

Climate change benefits for giant petrels

Giant petrels (stock image). Credit: © Nick Dale / Adobe Stock Giant petrels will be "temporary" winners from the effects of climate change in the Antarctic region -- but males and females will benefit in very different ways, a new study shows. The study, by experts from the University of Exeter and the British Antarctic…
