Researchers say lab-grown retinal tissue shows blue cone cells in the developing foveola may convert into red and green cones under the influence of retinoic acid and thyroid hormones.
A 52-week phase 3 study found stronger blood sugar and weight-loss results for the once-daily pill, though higher rates of gastrointestinal side effects and treatment discontinuation may complicate its outlook.
Researchers from the SuperC consortium say a machine learning and quantum physics approach has produced two newly verified superconductors and could accelerate the broader hunt for materials that work at far higher temperatures.
A planned Independence Day spectacle in the nation’s capital is expected to feature more than 850,000 pyrotechnic effects, while internal federal analysis warns of short-term air quality risks around the National Mall.
The space agency is tying the U.S. semiquincentennial to astronomy programming, new Hubble imagery and digital activities centered on the telescope’s long-running mission.
