Kirigami, inverse design with no advanced computational tools

MathematicsPhysics

By Mapping Ignorance

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 […]

The light of someone’s life might not be just another person, but light in the literal sense. According to a recent study , every living system emits light without requiring external excitation due to a biological phenomenon known as ultraweak photon emission (UPE). In mice, UPE was linked to vitality as live mice emitted significantly […]

What if the universe rotates?

What if the universe rotates?

AstrophysicsCosmology

By Mapping Ignorance

A new study suggests the universe may rotate—just extremely slowly. The finding could help solve one of astronomy’s biggest puzzles. Current models say the universe expands evenly in all directions, with no sign of rotation. This idea fits most of what astronomers observe. But it doesn’t explain the so-called Hubble tension—a long-standing disagreement between two […]

First video of catalysis in action at the atomic level

CatalysisChemistry

By Mapping Ignorance

An international team of scientists has, for the first time, directly observed catalysis in-action at the atomic level. In mesmerizing new videos, single atoms move and shake during a chemical reaction that removes hydrogen atoms from an alcohol molecule. By viewing the process in real time, the researchers discovered several short-lived intermediate molecules involved in […]

Using the 10.4-m Gran Telescopio Canarias (GTC), astronomers have detected methane in the atmosphere of WISEA J181006.18−101000.5—the closest T dwarf to Earth. Brown dwarfs are intermediate objects between planets and stars. Astronomers generally agree that they are substellar objects occupying the mass range between 13 and 80 Jupiter masses. One subclass of brown dwarfs (with […]

How perceptions are influenced by expectations

How perceptions are influenced by expectations

NeurobiologyNeurolinguisticsNeurosciencePsychology

By Mapping Ignorance

Past neuroscience and psychology studies have shown that people’s expectations of the world can influence their perceptions, either by directing their attention to expected stimuli or by reducing their sensitivity (i.e., perceptual acuity) to variations within the categories of stimuli we expect to be exposed to. While the effects of expectations on perceptions are now […]

BiochemistryBiologyChemistry

By Mapping Ignorance

Life may not have begun with a dramatic lightning strike into the ocean but from many smaller “microlightning” exchanges among water droplets from crashing waterfalls or breaking waves. New research shows that water sprayed into a mixture of gases thought to be present in Earth’s early atmosphere can lead to the formation of organic molecules […]
