    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…

    Life. A mess…

    Life is built with three major components: RNA and DNA – the genetic code – and proteins, the cells that carry out their instructions. Most likely, the first cells had all three pieces. But first, RNA, DNA or proteins had to form without their partners. One common theory, known as the “RNA World” hypothesis, proposes…

    Being afraid of Nothing…

    Scientists have created the fastest spinning object ever made, taking them a big step closer to being able to measure the mysterious quantum forces at play inside ‘nothingness’. The record-breaking object will pave the way for scientists to detect unfathomably small amounts of drag caused by the ‘friction’ within a vacuum. The science of nothingness…

    Classical physics. QM. Intuitionism.

    In classical physics, it is accepted that everything has already been determined since the Big Bang. To explore the future of our cosmos, physicists employ the language of classical mathematics and represent the universe’s initial conditions conditions by real numbers. “These numbers are characterized by an infinite number of decimals that follow the dot,” says…

    Tractionless movement.

    Understanding how cells move autonomously is a fundamental question for both biologists and physicists. Experiments on cell motility are commonly done by looking at the motion of a cell on a glass slide under a microscope.  In those conditions, cells are observed to “crawl” on the surface. Crawling is well understood: cells attach themselves to…
