Science

A long-overlooked heavy neutrino could help explain why matter prevailed over antimatter

Phys.org says the particle's slow decay may have let it briefly dominate the early universe's energy density.

Arctic winter sea ice likely to shrink about 1 million square kilometers more than projected

Phys.org reports the projection draws on clues from a warmer Arctic 6,000 years ago.

Seasonal CO₂ exchange swings grew 48% in the equatorial Indian Ocean from 1980 to 2019

Phys.org reports that larger seasonal swings do not necessarily mean the ocean absorbed more carbon overall.

Three silicon spin qubits exceed 99.99% gate fidelity while operating simultaneously

Phys.org reports the qubits operated through one shared microwave line, limiting errors that typically reduce accuracy during parallel control.

Electrical pulses switch four-layer graphene between magnetic and nonmagnetic states

Phys.org reports that the states persist after voltage is removed; pulses slide graphene's layers into different atomic arrangements.
