The farthest galaxy…
A team of astronomers used the Keck I telescope to measure the distance to an ancient galaxy. They deduced the target galaxy GN-z11 is not only the oldest galaxy but also the most distant. It's so distant it defines the very boundary of the observable universe itself. The team hopes this study can shed light…

The bar mystery…
The majority of spiral galaxies, like our home the Milky Way, host a large bar-like structure of stars in their canter. Knowledge of the true bar size and rotational speed is crucial for understanding how galaxies form and evolve. However our galaxy's bar size and rotational speed have been strongly contested in the last 5…

Computations
Scientists have borrowed a technique from applied mathematics to rapidly predict the behavior of fusion plasma at a much-reduced computational cost. (1) Trying to compute things. But we will never do that. Unless we use the whole universe. And have it standing still. Just computing things. We will then know it all. And right then…

Grain… Seed… Born!
Researchers examined stable isotopes from bone collagen and dental enamel to reconstruct the diets of ancient Mongolians. Findings challenge the popular notion of a completely nomadic prehistoric population, linking grain cultivation with the success of the Xiongnu Empire (c. 200 BCE-150 CE) and showing continual grain consumption during the Mongol Empire of the Khans (c.…

Ancestral asymmetries…
The left and right side of the brain are involved in different tasks. This functional lateralization and associated brain asymmetry are well documented in humans, but little is known about brain asymmetry in our closest living relatives, the great apes. Using endocasts (imprints of the brain on cranial bones), scientists now challenge the long-held notion…
