Phys.org / Three-dimensional visualization of nanoplastic distribution in the neonatal mouse brain

Nanoplastics—plastic particles smaller than one micrometer—are generated through the degradation and abrasion of plastic products and are increasingly detected in food, drinking water, air and biological tissues. Although ...

Phys.org / 2D quantum memory device reaches single-electron limit of information storage

Most electronic memory storage devices require the ability to trap large numbers of electrons for each bit of memory. In an ideal world, however, it would take only one electron. This would reduce space requirements and power ...

Phys.org / Strain turns non-chiral crystals left- or right-handed on demand

Mechanical strain is one of the most common tools used to tailor the properties of materials. In piezoelectric materials, stretching or compressing a crystal generates an electrical polarization. In piezomagnetic materials, ...

Phys.org / Non-monogamy may reduce jealousy overall, but feeling less desirable can still strain relationships

Comparing yourself with your partner is more common than you'd think. Psychologists even have a term for it: mate value discrepancy (MVD), which is the gap between how attractive, smart or successful each partner feels compared ...

Phys.org / Bringing complex field physics to the tabletop: A photonic stage for non-Abelian gauge fields

For most theories in physics, the order of operations has little impact on the result. When setting a dial to a certain position, for example, it doesn't matter whether it's turned clockwise or counterclockwise—the result ...
