If you’re far from the Equator, most birds tend to have drab colors, but the closer you … Read more

How iBuyers are changing real estate racial disparities and individual homeownership rates in one major city

How iBuyers are changing real estate racial disparities and individual homeownership rates in one major city

University of Washington researchers investigated how iBuyers—companies that use automated algorithms to quickly buy and sell homes—have affected the well-documented racial bias against Black home sellers. In Mecklenburg County, North Carolina, they found that on average iBuyers paid more equal prices to Black and white home sellers than individual buyers, largely because iBuyers paid white … Read more

Construction of multi-element co-segregated grain boundary complexion

Construction of multi-element co-segregated grain boundary complexion

In un-doped ZrO2-SiO2 system, the GBs between ZrO2 nanocrystallites were clean without dopant segregation. When heating the material, Zr and O atoms could easily cross the GBs, resulting in grain coarsening. In comparison, when multiple dopants were added to the material system, GB complexions with multiple dopants co-segregated were formed. The GB complexions acted as … Read more

‘Miracle’ filter turns store-bought LEDs into spintronic devices

Stack of the spin-LED emitting circularly polarized electroluminescence. The (R-MBA2Pbl) acts as a spin filter, allowing only polarized carriers (blue circles) to flow through the LED and recombine in the multiple quantum wells (MQW)s emitting circularly polarized light (yellow helix).

Homeless service providers could help more people if they measured success differently, researcher says

Credit: Unsplash/CC0 Public Domain Homelessness is a major problem in the U.S., and it’s getting worse: A record 650,000 Americans were homeless on a single night in January 2023, according to the most recent point-in-time report released by the U.S. Department of Housing and Urban Development. That amounts to 1 out of every 500 people … Read more
