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…

Simple questions…
On some days, time flies by, while on others it seems to drag on. A new study from JNeurosci reveals why: time-sensitive neurons get worn out and skew our perceptions of time. (1) Senses based on specific cells or neurons. Perception based on specific body functions. What is the correct perception? What is the false…

Weird planets…
Peculiar planetary system architecture around three Orion stars explained: In our Solar System, the eight planets and many other minor objects orbit in a flat plane around the Sun; but in some distant systems, planets orbit on an incline -- sometimes a very steep one. New work could explain the architecture of multi-star systems in…

Fitness. Change. Stupid mirrors…
There's a paradox within the theory of evolution: The life forms that exist today are here because they were able to change when past environments disappeared. Yet, organisms evolve to fit into specific environmental niches. How do these mechanisms co-exist? A research tried to answer that question. There are two general possible solutions. First, the…

Rough.
Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that…
