Physicists see light waves moving through metal
Conduction of light in a metal: waveguides are observed in a semi-metal known as ZrSiSe. Credit: Nicoletta Barolini, Columbia University When we encounter metals in our daily life, we perceive them as…
An MIT physicist on the mystery of dark matter in a lecture at Harvard
Scientists know dark matter exists because even though we can’t see it, we can see the effects of what it’s doing in the world, much like a ghost bumping around a haunted…
New maps of ancient warming reveal strong response to carbon dioxide
Enlarge / World map of the evolution of precipitation due to warming 56 million years ago: green = wetter, brown = drier. The circles show where the geologic data shows it has…

Dramatic New Webb Telescope Images Show Collision of Galaxies 270 Million Light-Years Away
This NASA/ESA/CSA James Webb Space Telescope image depicts IC 1623, a pair of … [+] interacting galaxies that lie approximately 270 million light-years from Earth in the constellation Cetus. The two galaxies…
Nano-sized islands open possibilities for the application of single-atom catalysts
Credit: Unsplash/CC0 public domain A new method for anchoring single atoms of platinum-group metals to nanometer-sized islands makes it possible to effectively use these expensive metals as catalysts for a wide variety…
Researchers compress light 12 times below the diffraction limit in a dielectric material
Fabrication of a Topology Optimized Dielectric Silicon Bowtie Cavity (DBC). a Rendering of the DBC design generated by optimizing the constrained-to-tolerance topology. The normalized ā£Eā£ field is projected on the faces defining…
Galactic collision: Webb Space Telescope explores frenetic star formation in merged galaxies
The two galaxies swirl into a single chaotic object in the center. Long blue spiral arms extend vertically, weak at the edges. The hot gas is spreading horizontally across it, mostly bright…
