Stonehenge served as an ancient solar calendar - new analysis
Mar 07, 2022 (SPX)
New finds about the stone circle's history, along with analysis of other ancient calendar systems, prompted Professor Timothy Darvill to take a fresh look at St...
Closest black hole system found to contain no black hole
Mar 03, 2022 (SPX)
The original study on HR 6819 received significant attention from both the press and scientists. Thomas Rivinius, a Chile-based ESO astronomer and lead author o...
A new way to control atomic interactions
Mar 01, 2022 (SPX)
These shapes were produced not by physically moving the atoms, but by controlling the way atoms exchange particles and "sync up" to share certain properties. By...
Quantum boomerang
Mar 01, 2022 (SPX)
"It's really a fundamentally quantum mechanical effect," said atomic physicist David Weld, whose lab produced the effect and documented it in a paper published ...
New evidence proves acceleration of quasar outflows at scale of tens of parsecs
Feb 28, 2022 (SPX)
According to modern theories on galactic formation and evolution, the mechanism of Active Galactic Nuclei (AGN) feedback suggests that the gigantic black hole a...
Scientists reveal 4.4 million galaxies in a new map
Feb 28, 2022 (SPX)

Physicists observe an exotic multiferroic state in an atomically thin material
Feb 24, 2022 (SPX)
"Two-dimensional materials are like LEGOs - you put one on top of another to make something different from either piece alone," says study author Nuh Gedik, pro...
Evidence for exotic magnetic phase of matter
Feb 23, 2022 (SPX)
The new magnetic state involves strong magnetic attraction between electrons in a layered material that make the electrons want to arrange their magnetic moment...
Credit card-sized device focuses terahertz energy to generate high-resolution images
Feb 21, 2022 (SPX)
Terahertz waves, located on the electromagnetic spectrum between microwaves and infrared light, exist in a "no man's land" where neither classic electronics nor...
JILA atomic clocks measure Einstein's general relativity at millimeter scale
Feb 17, 2022 (SPX)
The experiments, described in the Feb. 17 issue of Nature, suggest how to make atomic clocks 50 times more precise than today's best designs and offer a route t...
Time crystals leave the lab
Feb 17, 2022 (SPX)
Scientists have recently discovered that a similar effect can be witnessed in time. Symmetry breaking, as the name suggests, can arise only where some sort of s...

Einstein's photoelectric effect: The time it takes for an electron to be released
Feb 11, 2022 (SPX)
Although the photoelectric effect in molecules has been studied extensively in the meantime, it has not yet been possible to determine its evolution over time i...
Early findings from HERA telescope promise deeper understanding of the cosmic dawn
Feb 11, 2022 (SPX)
HERA researchers are looking for the earliest signs of star formation and galaxy structure. Specifically, scientists including Jacqueline Hewitt, the Julius A. ...
