Structural insights into light-driven anion pumping in cyanobacteria

Here, the authors present four high-resolution structures of SyHR protein from cyanobacterial anion pumps family: chloride and sulfate bound forms and two active state structures. These structures provide insights into the molecular mechanisms of SyHR and cyanobacterial anion pumps in general.

Widespread horse-based mobility arose around 2200 bce in Eurasia

Analyses of 475 ancient horse genomes show modern horses emerged around 2200 bce, coinciding with sudden expansion across Eurasia, refuting the narrative of large horse herds accompanying earlier migrations of steppe peoples across Europe.

A subgroup of light-driven sodium pumps with an additional Schiff base counterion

Light-driven sodium-pumping rhodopsins are unique ion transporters. Here, authors present a characterization of such rhodopsins with a modified active center allowing for efficient sodium transport under various environmental conditions.

Observation of an ultra-high-energy cosmic neutrino with KM3NeT

A very high-energy muon observed by the KM3NeT experiment in the Mediterranean Sea is evidence for the interaction of an exceptionally high-energy neutrino of cosmic origin.

Femtosecond-to-millisecond structural changes in a light-driven sodium pump

Crystallographic ‘snapshots’ taken at intervals of femtoseconds to milliseconds after activation show how a light-activated sodium pump carries sodium ions across the cell membrane.

A wide and collimated radio jet in 3C84 on the scale of a few hundred gravitational radii

Interferometric observations of 3C84 reveal a broad cylindrical jet a few hundred gravitational radii from the black hole, implying that the jet either undergoes a rapid lateral expansion on even smaller scales or is launched from the accretion disk.

Unperturbed inverse kinematics nucleon knockout measurements with a carbon beam

Initial- and final-state interactions distort the kinematics in particle knockout scattering experiments, complicating their interpretation. These effects are suppressed by detecting ¹¹B nuclei in quasi-free scattering of ¹²C ions from hydrogen.
