Tested in pigs, a new battery design offers a safer, more reliable alternative to standard power sources for ingestible medical devices. Swallowing a battery typically requires a trip to the emergency ...

Measurements of the reactivity of volatile organic compounds emitted by urban trees show that they contribute more to ground-level ozone than do other, human-produced forms of emissions. Trees lining ...

Significant changes in global policy are generally achieved only after long-fought struggles by coalitions of key players and advocates. In the case of nuclear arms control, scientists—especially ...

The 54-qubit quantum computer Euro-Q-Exa was networked into this supercomputer at the Leibniz Supercomputing Centre in Germany. Scaling up quantum computing, and the energy it would take to do so, is ...

Chirality, a geometric property that distinguishes an object from its mirror image, is a foundational concept in physics. It appears in the asymmetry of a hand, in the spiral of DNA, in the helicity ...

With strong magnetic fields and intense lasers or pulsed electric currents, physicists can reconstruct the conditions inside astrophysical objects and create nuclear fusion reactors. If matter is ...
