  1. Over the last two years, scientists have used NASA's James Webb Space Telescope to explore what astronomers refer to as Cosmic Dawn -- the period in the first few hundred million years after the big bang where the first galaxies were born.
  2. Fossils found on the shoreline of Lake Kariba in Zimbabwe represent a completely new dinosaur species. This remarkable find, named Musankwa sanyatiensis, marks only the fourth dinosaur species named from Zimbabwe.
  3. People who report early memory problems and whose partners also suspect they have memory problems have higher levels of tau tangles in the brain, a biomarker associated with Alzheimer's disease.
  4. Researchers found that mutated mouse embryos showing an abnormal epidermal differentiation and injected with mouse pluripotent stem cells grew large patches of mature epidermis derived from the donor cells that survived transplantation to adult mice and grew natural-looking fur. Injecting the embryos with human keratinoctyes produced sheets of semi-humanized skin, suggesting that this system could be developed further to grow autologous skin grafts for treating severe skin wounds.
  5. Researchers demonstrated a scalable, modular hardware platform that integrates thousands of interconnected qubits onto a customized integrated circuit. This 'quantum-system-on-chip' (QSoC) architecture enables them to precisely tune and control a dense array of qubits.
