Science Needs for a Terrestrial Biosphere Tipping Point Early Warning System

Reviews of Geophysics, Volume 64, Issue 4, December 2026.
Abstract Tipping points in the Earth system have the potential to cause major detrimental impacts to the biosphere and societies. Their inherent nonlinearity implies that even relatively small additional increases in external forcing might result in disproportionately large adjustments to components of the Earth system.

Patient‐reported outcomes and visual function after four refractive strategies in cataract surgery: A randomized controlled trial

Acta Ophthalmologica, Volume 104, Issue 8, Page 855-867, December 2026.
Abstract Purpose To evaluate patient‐reported outcome measures (PROMs) and visual function across four groups of public cataract patients: emmetropia, mini‐monovision, monovision with partial‐range of field (RoF) narrow intraocular lenses (IOLs) and patients implanted with partial‐RoF extended IOLs.

Rare Multiple Ionospheric Disturbances Observed During the Artemis‐II Lunar Flyby Voyage

Geophysical Research Letters, Volume 53, Issue 22, 28 November 2026.
Abstract The total electron content observations during the Artemis‐II Lunar mission revealed rare ionospheric perturbations occurring at three different occasions. The launch at 2235 UT on 1 April 2026 from Kennedy Space Center induced shock‐acoustic and gravity wave modulations.

Free‐Standing Bilayer Metasurface With Physically Separated Phase Modulations for Low‐Crosstalk Polarization Multiplexing

Nanophotonics, Volume 15, Issue 22, 25 November 2026.
This paper presents a free‐standing bilayer spin‐decoupled metasurfaces that achieves almost complete decoupling of two circular polarization channels by physically separating the geometric phase and propagation phase modulations into distinct layers.

Observation of Return‐Stroke Current Wave Speed in a Long Channel Formed by Preceding Upward Connecting Leader

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Direct measurements of return‐stroke current propagation speed inside lightning channels remain extremely challenging, so the propagation speed of return‐stroke luminosity is widely used as a proxy. We present the first direct measurement of return‐stroke current propagation speed along a natural lightning channel, using synchronized lightning
