Author: Jeremiah Bartz, Associate Professor of Mathematics, University of North Dakota A shard of smooth bone etched with irregular marks dating back 20,000 years puzzled archaeologists until they noticed something unique – the etchings, lines like tally marks, may have represented prime numbers. Similarly, a clay tablet from 1800 B.C.E. inscribed with Babylonian numbers describes […]
PET (polyethylene terephthalate), a widely used polymer in packaging due to its favourable properties, increases rapidly in global plastic production and waste. Between 2000 and 2019, global plastic production rose from 234 to 460 million tonnes and is projected to reach 1,231 million tonnes by 2060. As a result, plastic waste more than doubled from […]
I finished my last entry expressing my perplexity by the ‘solution’ mathematicians offered six decades ago to the problem of the continuum : Cohen’s theorem according to which both the assumption that there is some set (say, C) larger than the set of natural numbers but smaller than the set of real numbers, and the […]
In the realm of modern physics, few materials have captured the imagination quite like graphene, a single layer of carbon atoms arranged in a honeycomb lattice. Its remarkable properties, such as exceptional electrical conductivity and strength, have made it a cornerstone of research into quantum materials. A recent study published in Nature takes this fascination […]
Author: Ari Koeppel, Postdoctoral Scientist in Earth and Planetary Science, Dartmouth College Andy Weir’s bestselling story “The Martian” predicts that by 2035 NASA will have landed humans on Mars three times, perfected return-to-Earth flight systems and collaborated with the China National Space Administration. We are now 10 years past the Hollywood adaptation’s 2015 release and […]
Kirigami is a traditional Japanese art form that entails cutting and folding paper (origami is just folding it) to produce complex three-dimensional (3D) structures or objects. Over the past decades, this creative practice has also been applied in the context of physics, engineering, and materials science research to create new materials, devices and even robotic […]
All cellular life as we know it today stems from a single common ancestor, from which all modern lineages emerged. The origin of cellular life is thought to be the node in the Tree of Life from which Archaea and Bacteria, the two primary domains, diverged. The universality of some features across cellular life evidences […]
New bacterium found on Tiangong space station Researchers have discovered a previously unknown bacterium, Niallia tiangongensis, on China’s Tiangong space station. The bacterium, found in swabs taken by the Shenzhou-15 crew, shows unique traits that may help it survive the harsh space environment. Full Story: ScienceAlert Unique facial tattoos discovered on 800-year-old mummy Researchers have […]

Nanotechnology is like a playground for scientists, where they tinker with materials at the scale of atoms to create new tools and devices with extraordinary properties. One of the most exciting areas in this field involves nanographenes, which are tiny pieces of graphene—a single layer of carbon atoms arranged in a honeycomb pattern, known for […]
Author: Sergi Basco, Adjunct Professor of Economics, Universitat de Barcelona A global reserve currency is one that is extensively held by foreign Central Banks. Since the 1944 Bretton Woods agreement this position has been occupied by the US dollar and it still holds true – according to IMF data from late 2024, the dollar represented […]
