Engineers describe how fluid suspensions exhibit different behaviors at different scales
Honey is already a thick liquid, but let it begin to crystalize and it can become downright clumpy. The sugar crystals in suspension seem to increase its viscosity. This phenomenon occurs throughout the natural and constructed world: From mudflows to.....»»
Miniature magnetic resonance imager made of diamond
The development of tumors begins with miniscule changes within the body's cells; ion diffusion at the smallest scales is decisive in the performance of batteries. Until now, the resolution of conventional imaging methods has not been high enough to r.....»»

Married couples and long-term romantic partners typically engage in a variety of behaviors that sustain and nourish the relationship. These actions promote higher levels of commitment, which benefits couples' physical and psychological health. A new.....»»
Researchers: Slow solutions to fast-moving ecological crises won"t work—changing basic human behaviors must come first
As the world grapples with multiple ecological crises, it's clear the various responses over the past half century have largely failed. Our new research argues the priority now should be addressing the real driver of these crises—our own maladaptiv.....»»
Scientists present the first set of global maps showing geographic patterns of beta-diversity in flowering plants
Beta-diversity serves as a crucial metric for gauging shifts in species composition over spatial or temporal scales, bridging the spectrum between localized (alpha) and broader regional (gamma) diversity. In the fields of ecology, biogeography and co.....»»

Research: Electrons in a strange metal world
Imagine a flock of birds as they wheel across the sky: surging into a mass, flowing into ribbons that twist and turn again into fantastic shapes. If you follow one bird within the flock, you can describe its actions, the way it flaps its wings or use.....»»
Using DNA as glue to hold nanostructures together and build ultra-strong colloidal crystal metamaterials
A team of chemical and biological engineers working with a group of nanotechnologists at Northwestern University in Illinois has developed a type of super-strong colloidal crystal metamaterial by gluing together metal nanostructures using strands of.....»»
Hyundai recalls 1.6 million gas-powered cars due to potential car fires
The problem is an ABS module that can leak brake fluid, causing a short, then fire. Enlarge (credit: Getty Images) After making lots of headlines due to the extremely easy-to-steal nature of some of its cheapest models,.....»»
Metaphors for human fertilization are evolving, study shows
In a common metaphor used to describe human fertilization, sperm cells are competitors racing to penetrate a passive egg. But as critics have noted, the description is also a "fairy tale," rooted in cultural beliefs about masculinity and femininity......»»
