Influence of gravity waves on the climatology of high-altitude Martian carbon dioxide ice clouds [PDF]
Carbon dioxide (CO2) ice clouds have been routinely observed in the middle atmosphere of Mars. However, there are still uncertainties concerning physical mechanisms that control their altitude, geographical, and seasonal distributions.

Can PV or solar thermal systems be cost effective ways of reducing CO 2 emissions for residential buildings? [PDF]
This paper compares two solar systems, an actual building integrated, photovoltaic roof (BIPV) and a notional solar thermal system for a residential block in London, UK.

core
A food‐grade cooling composite made from starch and recycled eggshell powder offers a scalable, ultra‐low‐cost solution for passive daytime radiative cooling. Easily prepared using basic kitchen tools, this material empowers communities, even in areas with limited infrastructure, to stay cooler during worsening summer heat waves.

Ozone chemical equilibrium near the Martian nighttime OH* layer: observational constraints
Simultaneous measurements of ozone concentrations and vibrationally excited hydroxyl (OH*) emissions provide a method for determining atomic oxygen (O) and atomic hydrogen (H) concentrations, which are otherwise difficult to measure directly.

A chiral photodetector capable of selectively distinguishing left‐ and right‐handed circularly polarized light is experimentally demonstrated. The device, which features a nanopatterned electrode inverse‐designed by a genetic algorithm within a metal–dielectric–metal nanocavity that incorporates a vacuum‐deposited small‐molecule multilayer, exhibits ...

Ceres: Organic‐Rich Sites of Exogenic Origin?
Ceres, the largest object in the asteroid belt, is the only potential ocean world in the inner Solar System. Previous studies identified deposits of aliphatic organics in and around the Ernutet crater, and at small locations at Inamahari and Urvara ...

Cyclic sunspot activity during the first millennium CE as reconstructed from radiocarbon
Context. Solar activity, dominated by 11-year cyclic evolution, has been observed directly since 1610 CE. Indirect cosmogenic proxy data have been used to reconstruct solar activity for millennia prior to 1610.
