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

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 […]

Condensed matterMaterials

By Mapping Ignorance

A team of researchers has experimentally demonstrated a quantum tornado for the first time by refining an established method. In the quantum semimetal tantalum arsenide (TaAs), electrons in momentum space behave like a swirling vortex. This quantum phenomenon was first predicted eight years ago. Scientists have long known that electrons can form vortices in quantum […]

A team of researchers has developed a reproducible and scalable method for producing graphene oxide (GO) nanosheets from commercial carbon fibres, marking a breakthrough in sustainable nanomaterial synthesis. The process involves exfoliating carbon fibres with nitric acid, which provides high yields of one-atom-thick sheets of graphene oxide with characteristics comparable to commercial GO sourced from […]

In a leap forward for quantum computing, a Microsoft team led by UC Santa Barbara physicists on Wednesday unveiled an eight-qubit topological quantum processor, the first of its kind. The chip, built as a proof-of-concept for the scientists’ design, opens the door to the development of the long-awaited topological quantum computer. “We’ve got a bunch […]

The surprising diversity of exploding white dwarfs

Astrophysics

By Mapping Ignorance

For decades, Type Ia supernovae have played a pivotal role in the discovery and study of dark energy—the mysterious force responsible for the accelerating expansion of the Universe. To do so, cosmologists compare two quantities: the redshift, i.e., the photon’s wavelength stretch caused by the geometrical expansion of the Universe ; and the Supernovae brightness […]
