Time-reversal-based quantum metrology with many-body entangled states
Linear quantum measurements with independent particles are bounded by the standard quantum limit, which limits the precision achievable in estimating unknown phase parameters. The standard quantum limit can be overcome by entangling the particles, but the sensitivity is often limited by the final state readout, especially for complex entangled many-body states...

Broadband metasurface superstrate for polarization-independent wave focusing and gain enhancement at Ka-band
A broadband metasurface flat lens is proposed as a polarization-independent wideband superstrate for wave focusing and gain enhancement at Ka-band. The proposed metasurface structure consists of four metal layers and is designed with diagonally symmetric unit cells to accommodate both the vertical and horizontal polarizations. The focusing ability of the proposed...
Isolation of hetero-telechelic polyethylene glycol with groups of different reactivity at the chain ends
Hetero-telechelic polymers (HTPs) with different reactive functional groups at the chain ends, which can react selectively with other molecules or surfaces to form new chemical bonds, are attractive in the context of reaction selectivity and elaborate polymer modification. However, effective synthetic routes to HTPs remain limited, especially those based on postpolymerization...
This map shows which US lakes contain brain-eating amoebas
A few days ago, a Missouri resident who went swimming in the Lake of Three Fires in Taylor County, Iowa, was hospitalized after a microscopic amoeba entered through their nose and started eating away at their brain. Better known as Naegleria fowleri, the single-celled organism that thrives in warm...
Observation of the all-optical Stern"“Gerlach effect in nonlinear optics
Celebrating its centennial anniversary, the Stern"“Gerlach experiment has proven to be one of the cornerstones of quantum mechanics, unravelling the quantized nature of the spin angular momentum, and being used in various applications ranging from matter-wave interferometry to weak measurements. Here we report an analogous all-optical Stern"“Gerlach experiment in nonlinear optics,...
Sub-nanometer mapping of strain-induced band structure variations in planar nanowire core-shell heterostructures
Strain relaxation mechanisms during epitaxial growth of core-shell nanostructures play a key role in determining their morphologies, crystal structure and properties. To unveil those mechanisms, we perform atomic-scale aberration-corrected scanning transmission electron microscopy studies on planar core-shell [email protected] nanowires on α-Al2O3 substrates. The core morphology affects the shell structure involving plane...
A computational approach to quantifying miscounting of radiation-induced double-strand break immunofluorescent foci
Immunofluorescent tagging of DNA double-strand break (DSB) markers, such as γ-H2AX and other DSB repair proteins, are powerful tools in understanding biological consequences following irradiation. However, whilst the technique is widespread, there are many uncertainties related to its ability to resolve and reliably deduce the number of foci when counting using...
Powerful Tonga Volcano Eruption Triggered Atmospheric Gravity Waves That Reached the Edge of Space
The eruption of Hunga Tonga-Hunga Ha’apai in January 2022 was unique in observed science, creating waves that reverberated around the earth and reached 100 km (60 miles) into the ionosphere. A new study has confirmed that one of the most explosive volcanic events of the modern era happened...
