The UCLA Academic Senate overwhelmingly passed a resolution Tuesday calling on administrators to reverse a decision to close the university’s childcare centers in June 2027.  UCLA will shut down the E...

An expert at the University of Copenhagen said his team had been sharing its research with the company’s A.I. model, Claude, and that its new finding matched their work.

UCLA will close its remaining child-care centers in June, leaving hundreds of families scrambling to find new care amid an acute countywide shortage.

We show that purely lossy defects in one- and two-dimensional non-Hermitian photonic crystals can induce transmission matrix singularities not accessible with lossless defects. These singularities in ...

Magneto-optic photonic systems can violate Kirchhoff's law of thermal emission by breaking Lorentz reciprocity. We develop a dispersive perturbation theory yielding an analytical expression for magnet...

Development and application of the integrated linkage disequilibrium score (iLDS) reveals both selective pressures impacting the human gut microbiome and the mechanisms by which gut bacteria adapt to ...

The number of first-year students at the University of California, San Diego, whose math skills fall below a middle school level has increased nearly 30-fold over the past five years, according to a n...

Space applications require the highest performing photovoltaic devices. Typically these are multi-junction devices that are capable of converting a larger bandwidth of the solar spectrum. However, the...

In passive sky-facing radiative cooling, wavelength-selective thermal emitters in the atmospheric transparency window of 8-13 $μ$m can reach lower temperatures compared to broadband emitters, but broa...

The Richmond resident, preservationist and chemical engineer, for whom William & Mary’s history department is named, also had the distinction of being the grandson of a man who became U.S. president i...

Nature Sustainability, Published online: 05 May 2025; doi:10.1038/s41893-025-01558-0Active radiant cooling is an emerging technology that consumes less energy than traditional air conditioning. This work demonstrates an outdoor radiant cooling structure incorporating infrared-reflective surfaces that delivers enhanced thermal comfort.

Even after 60+ years, Lawrence of Arabia is one of the best-looking films out there; this video explores why. I got to see Lawrence of Arabia on a big screen last fall and it was stunning — the colors, the amount of de

Prior to WWII the U.S was a distant second in science and engineering. By the time the war was over, U.S. science and engineering had blown past the British, and led the world for 85 years. It happ…

Warming Mars with artificial aerosols appears to be feasible.

Tuning the spatial extent of directional thermal emission across an arbitrary, and fixed spectral bandwidth is a fundamentally enabling capability for a range of emerging applications such as thermoph...

We synthesized crystalline films of neodymium nickel oxide (NdNiO3), a perovskite quantum material, switched the films from a metal phase (intrinsic) into an insulator phase (electron-doped) by field-...

With drones and A.I., researchers managed to double the number of mysterious geoglyphs in a matter of months.

Voltage conversion is a fundamental electronic process critical to engineered systems across a wide spectrum of applications and spanning many orders of magnitude in scale. Conventional approaches lik...
