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…

Dichotomies…
In a study published in Nature Astronomy, researchers from the United States and Japan unveiled the possible origins of our cosmic neighborhood’s “Great Divide”. A well-known schism which resulted to have on the one side the “terrestrial” planets, such as Earth and Mars and on the other side the more distant planets such as Jupiter…

Measuring… (What?)
A new optical atomic clock makes ultra-precise time measurements. (1) Measuring time. Even though we are not certain what time is. You see, not knowing something does not hinder you from handling it. But this goes even further than that. Not knowing something is the sole pre-requisite of handling it. Because if you knew it,…

Growing in darkness…
New research reveals how a week in the dark rewires brain cell networks and changes hearing sensitivity in adult mice long after the optimal window for auditory learning has passed. With further study, cross-modal learning — the manipulation of one sense to induce change in another sense — could be used to help people with…

Elusive motion… Only if still moving…
In temperatures millions of times colder than interstellar space, researchers have performed the coldest reaction in the known universe. But that’s not all. In such intense cold, their molecules slowed to such glacial speeds, they could see something no one has been able to see before: the moment when two molecules meet to form two…
