Phys.org / Molecular orbitals imaged in 3D, opening path to femtosecond videos

One of the most famous and intriguing results of quantum mechanics is the finding that fundamental particles, such as electrons, cannot be pinned down to one single location. Instead, a particle is described by its "wavefunction," ...

Phys.org / Egg oiling offers a targeted way to reduce raven predation on vulnerable prey

Common ravens are intelligent omnivores that regularly consume the eggs and young of nesting birds, and their populations are boosted by human-provided food and nesting resources. This has resulted in elevated predation by ...

Medical Xpress / New insights into the evolution of a gene linked to neurodevelopmental conditions

Certain variants in the PSPH gene, which encodes an enzyme called phosphoserine phosphatase, prevent the body from making sufficient amounts of the amino acid L-serine, leading to a range of nervous system problems. New research ...

Phys.org / Quantum fluid reveals hidden states that can be switched with a magnetic field

Bose-Einstein condensates (BECs) are often described as a "fifth state of matter": a quantum state in which many particles lose their individual identities and behave as one collective object. For more than 60 years, researchers ...
