Twice a day, Mars may briefly host water that could support life
Frost-covered regions present the best candidates for the future habitability of Mars and further astrobiological exploration, research into brines shows. Mars, once thought too cold and dry for liquid water, may briefly host salty brines twice a day during certain seasons. These fleeting bursts wouldn’t be enough to sustain humans, but they could have supported hardy life in Mars’ past—and may guide future missions searching for signs of it.
Due to extreme temperatures and the dryness of Mars, it’s thought to be impossible for liquid water to form on the planet’s surface, a critical precondition for habitability. The only hope of finding liquid water appears to be in the form of brines, which are liquids with high concentrations of salts that can freeze at much lower temperatures. But the question of whether brines can even form on Mars has yet to be answered.
Vincent Chevrier, an associate research professor at the University of Arkansas’ Center for Space and Planetary Sciences, has been studying that question for 20 years and now thinks he knows the answer: ‘yes they can.’
Symmetry-based Floquet optical selection rules help explain light-induced sidebands
Researchers at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD), in collaboration with international partners, have developed momentum-resolved Floquet optical selection rules. They show how these symmetry-based rules determine the spectral weight distributions of photon-dressed sidebands in time- and angle-resolved photoemission spectroscopy (TrARPES) experiments across different pump-probe configurations. This fundamental work has now been published in Science Advances.
Scientists Crack the Code of China’s Mysterious “Matrix Tide”
Last year, spectators along China’s Qiantang River witnessed an unusual sight: waves arranging themselves into a grid-like formation.
This striking pattern, named the “matrix tide,” arose from the river’s famous tidal bores that rush upstream against the flow. In this case, two undular bores — shockwave-like surges that spread outward like ripples on water — traveled in different directions and collided, creating the effect.
