Genetic analysis identified a previously unrecognized gentoo penguin species on the Kerguelen Islands and showed that gentoos comprise four distinct species. The study also warns that warming oceans could leave several island populations with little suitable habitat by 2050.

Oak Ridge National Laboratory researchers used inexpensive aluminum-based molten salts to break polyethylene into smaller hydrocarbons under relatively mild conditions. The process produced a mixture containing about 60% gasoline-range fuel, along with diesel-like products.
9:08 AMScienceDaily
Researchers developed a flexible, needle-thin implant that can record neural activity, deliver drugs, and stimulate several brain regions through one fiber. Tests in mice suggest the device could support more precise brain research and eventually neurological treatments.

NASA has activated the Nancy Grace Roman Space Telescope's 300-megapixel infrared camera, which will survey large regions of the universe at Hubble-like sharpness. Its coronagraph, designed to study exoplanets, is also operating as expected, with science operations planned for 2027.

A large Amazon analysis found that protecting existing forests from fire and logging produced the strongest biodiversity gains and nearly matched deforestation prevention for carbon storage. Restoration helped in heavily cleared areas but cost more and was less effective when used alone.
7:54 AMScienceDaily
Researchers found that the human brain develops from two distinct cellular systems, suggesting that evolution combined ancient nervous systems with different functions. The work also enabled them to grow human hindbrain neurons in the laboratory for disease research.
