Seagrasses provide the foundation of one of the most highly biodiverse‚ yet vulnerable‚ coastal marine ecosystems globally. They arose in three independent lineages from their freshwater ancestors some 100 million years ago and are the only fully submerged‚ marine flowering plants.

The spongelike structure of metal-organic frameworks (MOFs) allows these polymers to possibly carry and deliver a range of therapeutic compounds. Now‚ researchers reporting in ACS Applied Bio Materials have treated a chromium-containing MOF with a dose of acetic acid‚ more concentrated than in vinegar‚ to expand its pore size and surface area. The puffed-up MOF held more ibuprofen or chemotherapy drug than the original version and showed improved performance as a potential drug-delivery vehicle.

Imagine a catastrophic event that blocked out the sun‚ such as the eruption of a large volcano‚ or even a nuclear war.

What happens when you expose tellurite glass to femtosecond laser light? That's the question that Gözden Torun at the Galatea Lab at Ecole Polytechnique Federale de Lausanne‚ in collaboration with Tokyo Tech scientists‚ aimed to answer in her thesis work when she made the discovery that may one day turn windows into single material light-harvesting and sensing devices. The results are published in Physical Review Applied.

If life ever existed on Mars‚ the Perseverance rover's verification of lake sediments at the base of the Jezero crater reinforces the hope that traces might be found in the crater.

They are among the most productive and biodiverse areas of the world's oceans: coastal upwelling regions along the eastern boundaries of the Atlantic and Pacific Oceans. There‚ equatorward winds cause near-surface water to move away from the coast. This brings cold‚ nutrient-rich water from the depths to the surface‚ inducing the growth of phytoplankton and providing the basis for a rich marine ecosystem in these regions.

A recently discovered solar system with six confirmed exoplanets and a possible seventh is boosting astronomers' knowledge of planet formation and evolution. Relying on a globe-spanning arsenal of observatories and instruments‚ a team led by researchers at the University of California‚ Irvine has compiled the most precise measurements yet of the exoplanets' masses‚ orbital properties and atmospheric characteristics.

Recording the activity of large populations of single neurons in the brain over long periods of time is crucial to further our understanding of neural circuits‚ to enable novel medical device-based therapies and‚ in the future‚ for brain–computer interfaces requiring high-resolution electrophysiological information.

A group of survivors of Nazi death camps will mark the 79th anniversary of the liberation of the AuschwitzBirkenau camp during World War II in a modest ceremony Saturday in southern Poland.

Columbia engineers have built a new AI that shatters a long-held belief in forensics–that fingerprints from different fingers of the same person are unique. It...
