Glowing Algae Change Morphology to Avoid Light
Bright light triggers the chloroplast of a bioluminescent algae to fold into a pattern that minimizes the chloroplast’s exposed area. Continue reading
An Astronomer’s Appeal for Satellite Regulation
Samantha Lawler would like to see more done to reduce the detrimental impact of satellites on dark skies, telescope data, and publicly funded research. Continue reading
Adding Certainty to Plutonium’s Fission Yield
A first-of-its-kind measurement reveals the energy spectrum of the neutrons produced during the fission of plutonium, a common nuclear fuel component. Continue reading
Spider-Inspired Microphone Detects Tiny Gusts of Sound
A small device senses sounds using a spiderweb-like design—a strategy that could lead to chip-size microphones that are less affected by thermal noise. Continue reading
A Better Way to Charge a Quantum Battery
Coupling the charger and battery to a common reservoir induces a direct flow of energy into the battery. Continue reading

Filamentation Observed in Wakefield Acceleration
A particle-beam-generating method—called wakefield acceleration—uses proton bunches, which can fragment into high-density filaments as a result of their interactions with plasma, new experiments show. Continue reading
Lithium-Ion “Traffic Jam” Behind Reduced Battery Performance
Real-time in situ x-ray observations of new nickel-rich lithium-ion batteries reveal that reduced performance comes from lithium ions getting trapped in the cathode. Continue reading
Quantum Machine Learning Goes Photonic
Measuring a photon’s angular momentum after it passes through optical devices teaches an algorithm to reconstruct the properties of the photon’s initial quantum state. Continue reading
