Investigating quantum and molecular plumbing in nanofluidics research‎

Our body contains an intricate system of tiny vessels through which blood, water and other molecules flow. When the size of the pipes shrinks to the nanoscale, where only a few molecules can fit side by side, the classical laws of physics governing the behavior of water are influenced by the atomic structure of the walls. "It's not that classical hydrodynamics breaks down, but rather that it gets mixed with the condensed matter physics of the solid walls," says Nikita Kavokine, tenure-track assistant professor and leader of the EPFL Quantum Plumbing Lab.

Marmoset monkeys adapt their voices to sound more like their social partners, study finds‎

Many animal species that live in groups are known to adjust their behavior to strengthen their social bonds or increase their coordination with others around them. For instance, humans and some other animals exhibit vocal plasticity, meaning they tend to modify the sounds they produce based on their past experiences and the peers they have interacted with.

125-million-year-old fossil reveals 'pregnant' shellfish‎

An international team of scientists led by Dr. Graciela Delvene of the Geological and Mining Institute of Spain (CSIC) has uncovered the oldest known evidence of maternal care in shellfish, revealing that some freshwater species were protecting and incubating their young more than 125 million years ago. Published today in Scientific Reports, the new research found fossilized soft tissues preserved inside ancient shells. This is a remarkable discovery because such tissues normally decay soon after an animal dies. Among these tissues were microscopic embryos and larvae preserved within the gills.

Digital know-how, not just money basics, may ease retirement anxiety‎

A Hiroshima University-led study conducted with Rakuten Securities finds that practical digital skills, positive financial attitudes and self-protection are more consistently associated with lower old-age anxiety than traditional financial knowledge alone.

Electron-Ion Collider's radiofrequency controls system passes first real-world test‎

The U.S. Department of Energy's (DOE) Brookhaven National Laboratory has reached a key early milestone in developing radiofrequency control systems for the Electron-Ion Collider (EIC)—a next-generation research facility that will collide electrons with ions to reveal how the building blocks of matter are held together.

New research advances amaranth as a nutritious and high-performing leafy green crop‎

Two complementary studies, appearing in HortScience, from Rutgers University are advancing the potential of amaranth (Amaranthus spp.) as a valuable leafy green by combining detailed morphological characterization with evaluations of horticultural performance and nutritional quality. Amaranth is gaining attention as a versatile crop with strong adaptability, rapid growth and high nutritional value.
