These ancient quasars shouldn't exist so soon after the Big Bang

Quasars rank among the brightest and most powerful objects in the universe. They are fueled by supermassive black holes that consume surrounding material at the centers of galaxies, producing so much energy that they can be seen across billions of light years. Now, an international team of researchers has identified…

Gallium was discovered in 1875 by French chemist Paul Émile Lecoq de Boisbaudran. It is best known for…

Trees keep absorbing carbon long after they stop growing

Trees do not necessarily keep growing for as long as they keep photosynthesizing, according to a new study published in Science Advances. Researchers found that oak trees continue absorbing carbon dioxide well after their annual growth has ended, suggesting forests may store less carbon in wood than many climate models…

A vitamin A discovery is changing what scientists know about vision

Scientists at Johns Hopkins University have uncovered how humans develop sharp central vision before birth, identifying a carefully timed interaction between a vitamin A derived molecule and thyroid hormones in the retina. The discovery challenges a decades old explanation for how key light sensing cells form and could guide future…
