Imagine a close basketball game that comes down to the final shot. The probability of the ball going through the hoop might be fairly low, but it would dramatically increase if the player were afforded the opportunity to shoot it over and over. A similar idea is at play in the scientific field of membrane […]
Pain is highly personal. What to some doesn’t even deserve the name, for others can be unbereable. Now, we just discovered a difference in how we feel it: men and women have different pain receptors. Recent research has demonstrated in rodents and, importantly, primates including humans, that there are sex differences in pain receptors, also […]
Newfound ancient reptile suggests complex ecosystems Paleontologists have uncovered a previously unknown species of small land reptiles, Parvosuchus aurelioi, that lived about 237 million years ago, walked on four legs and used bladelike teeth to tear flesh. “The presence of this small predator among fossils of much larger predators suggests that these ecosystems, where Brazil […]
Topology has been at the forefront of condensed matter physics for the past two decades, influencing our understanding of quantum materials and phenomena. More recently, it has however become clear that a more general concept, that of quantum geometry, manifests itself in a series of quantum phenomena involving flat electronic bands. In condensed matter physics […]
Author: Ambuj Tewari, Professor of Statistics, University of Michigan Over 100 years ago, Alexander Graham Bell asked the readers of National Geographic to do something bold and fresh – “to found a new science.” He pointed out that sciences based on the measurements of sound and light already existed. But there was no science of […]
About 2.5 billion years ago, free oxygen, or O2, first started to accumulate to meaningful levels in Earth’s atmosphere, setting the stage for the rise of complex life on our evolving planet. Scientists refers to this phenomenon as the Great Oxidation Event, or GOE for short. But the initial accumulation of O2 on Earth was […]
Angela Potochnik’s Idealization and the Aims of Science is probably one of the most interesting and ambitious philosophy of science books of the last years. It offers a picture of scientific knowledge and of its production that elaborates on, and wisely amends, some of the best literature in the recent ‘pragmatist’ tradition of philosophy of […]
Earth’s inner core may have started slowing spin in 2010 Seismograms confirm Earth’s inner core has slowed its rotation for the first time in decades, possibly beginning in 2010 because of gravitational pull or the liquid iron outer core’s constant motion, which generates the planet’s magnetic field. The slowdown could change the length of a […]
Carbon monoxide (CO) oxidation (2CO + O2 → CO2) on platinum (Pt) group metal surfaces is the model heterogeneous gas/surface catalytic reaction. Pt itself is of the upmost importance as a catalyst for car exhaust cleaning or for the water gas shift reaction, whereas Pt crystal surfaces are model systems for investigating the catalytic CO […]
