Oct. 3, 2024 Toddlers in the UK obtain nearly half (47%) of their calories from ultra-processed foods (UPFs), and this rises to 59% by the age of seven, according to a new study. The most common UPFs consumed by the toddlers -- who were 21 months when their parents recorded their diets -- were flavored yogurts and wholegrain breakfast cereals, products typically seen as healthy. By the age of seven, the most ...

Oct. 7, 2024 Researchers have discovered the most distant Milky-Way-like galaxy yet observed. Dubbed REBELS-25, this disc galaxy seems as orderly as present-day galaxies, but we see it as it was when the Universe was only 700 million years old. This is surprising since, according to our current understanding of galaxy formation, such early galaxies are expected to appear more ...

Oct. 3, 2024 Looking deep into the early universe with NASA's James Webb Space Telescope, astronomers have found something unprecedented: a galaxy with an odd light signature, which they attribute to its gas outshining its stars. Found approximately one billion years after the big bang, galaxy GS-NDG-9422 (9422) may be a missing-link phase of galactic evolution between the universe's first stars and familiar, ...
