Phys.org / When humidity changes, so do the colors of sweat bees

Nature is a riot of color. In the animal kingdom, many species, from insects to cephalopods, use their permanent color or change it for communication, camouflage, and thermoregulation. While this type of reversible shift ...

Phys.org / Laser bursts flip nanoscale magnetic vortices at blistering speeds, opening a path to brain-like spintronics

Spintronics are devices that operate leveraging the spin, an intrinsic form of angular momentum, of electrons. The ability to switch magnetic states is central to the functioning of these devices, as it ultimately allows ...

Phys.org / CHIME tracks a hyperactive repeating fast radio burst source

Using the Canadian Hydrogen Intensity Mapping Experiment (CHIME), an international team of astronomers has performed radio observations of FRB 20220912A—a highly active source of repeating fast radio bursts. Results of the ...

Phys.org / Chromosomes condense in three timed chemical waves during cell division, study shows

DNA does not float freely in the cell. Instead, it is wrapped around histone proteins to form structures called nucleosomes. These histones carry numerous chemical modifications that act as molecular signals, controlling ...

Phys.org / This 2,200-year-old Roman wreck hid a repair story that rewrites how ancient ships survived long voyages

Ever since humans have embarked on sea voyages, they needed to ensure vessels were waterproof, resistant to salty seawater, and could withstand microorganisms or sea-dwellers like worms. Until the mid-20th century, however, ...

Medical Xpress / Smell loss may mark Alzheimer's start as olfactory damage map comes into focus

A research team has, for the first time, identified at the cellular level why the olfactory system is the first to be damaged in the early stages of Alzheimer's disease (dementia). The paper is published in the journal Alzheimer's ...

Phys.org / Re-engineered human cells boost gene-editing particle potency across multiple delivery systems

Gene editing has emerged as a powerful approach for targeting the genetic causes of disease, but getting the editing machinery into the right cells efficiently, safely, and at the scale needed for therapies remains one of ...

Phys.org / One-way phonon synchronization could survive noise and defects, theoretical physicists suggest

A novel approach for realizing the one-way quantum synchronization of phonons has been proposed by three theoretical physicists at RIKEN. Importantly, this method is remarkably resilient against practical challenges such ...

Phys.org / Inside the skull of a Devonian fish from Gondwana, revealed by neutron imaging

Flinders University researchers have taken a revealing look inside the head of one of the first animals to crawl from the water to live on land more than 380 million years ago. Using high-tech neutron imaging, they scanned ...

Phys.org / From the Pampas to Patagonia, DNA reveals South America's human history

A new genetic study shows that cultural diversity in the so-called Southern Cone—the roughly triangular southernmost part of South America—was strongly influenced by extensive human migration. An international research team ...

Phys.org / Nuclear war at Ukraine-Russia border could trigger years of global climate disruption and radioactive fallout

Geopolitical tensions in Eastern Europe underscore the urgency of addressing the climate and radiological consequences of a regional nuclear conflict. Even a small-scale nuclear conflict at the Ukraine–Russia border could ...
