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…

One… Two… Many…
Phase transitions describe dramatic changes in properties of a macroscopic system - like the transition from a liquid to a gas. Starting from individual ultracold atoms, physicists were able to observe the emergence of such a transition with an increasing number of particles. (1) One. Two. Three. Many. The whole cosmos can be explained by…

Time & Place…
Two new studies shed new light on how the brain encodes time and place into memories. The findings not only add to the body of fundamental research on memory, but could eventually provide the basis for new treatments to combat memory loss from conditions such as traumatic brain injury or Alzheimer's disease. (1) Take my…

Random predictability…
Scientists have generated a huge true random number using DNA synthesis. It is the first time that a number of this magnitude has been created by biochemical means. (1) Random. Based on something. But everything started from nothing. Think again. Look at the obvious as you once did. Without asking for anything but what you…

Weighting the Weightless…
It is thought that over 1,000 kilograms of so-called interplanetary dust falls to Earth every day. This dust is essentially an untold number of small faint meteors, discarded remnants of asteroids and comets that pass by the Earth. Two ways to study faint meteors are radar and optical observations, each with advantages and limitations. Astronomers…
