Hydration redirects electron-induced chemistry in uracil
This research indicates that even a single water molecule can suppress covalent bond rupture in electron-attached uracil and redirect the molecule toward water loss instead.

No compelling synchrotron pair echo candidates were found near KM3-230213A
This research indicates that none of the identified subthreshold gamma-ray sources near the KM3-230213A neutrino event seem to be compelling candidates for synchrotron pair echo emission.

Low-multipole CMB temperature power is lower than Planck prediction
This research indicates that the cosmic microwave background temperature power at multipoles below 30 is lower than expected from the best-fit Planck 2018 Lambda cold dark matter spectrum, with a low quadrupole, a dip at multipoles 20 to 27, and an overall low power level.

Reciprocating swimmer moves in viscoelastic granular hydrogel
This research indicates that a scallop-like swimmer can move in a cohesive granular hydrogel when its flapping frequency matches the material’s inverse relaxation time, and that the motion can reverse direction compared with cohesion-free granular material.

Wavefunction collapse yields emergent time and damped extra modes
This research indicates that wavefunction collapse in general relativity can produce emergent time, a monotonically increasing scale factor, and physical graviton modes, while strongly damping constraint-violating excitations.

Pruned moment tensor potentials run faster with minimal accuracy loss
This research indicates that post-training pruning can remove expensive basis functions from Moment Tensor Potentials with minimal loss of accuracy, producing models that are up to seven times faster.

Curvature drives chiral transport and entanglement in fermions
This research indicates that spacetime curvature and black hole horizons can shape real-time chiral transport, wave propagation, and entanglement in Dirac fermions through an effective magnetic field and position-dependent chiral chemical potential.

Starobinsky model remains compatible in parts of parameter space
This research indicates that parts of the Starobinsky inflation model can remain consistent with the latest observational data, and that adding a cubic R^3 correction can shift its predictions toward the Planck and ACT measurements.
