Phys.org / How proximity steals energy from nanoresonators
Nanomechanical resonators are miniature vibrating structures on chips that oscillate at frequencies ranging from a few kilohertz to gigahertz. They are used as ultrasensitive detectors of mass and force, temperature and pressure, ...
Phys.org / Simple cell migration mechanism may explain how hair follicles organize before birth
In mammals, hair follicles emerge during embryonic development, forming geometric patterns that vary from one species to another. But how is the position of each hair determined? A team from the University of Geneva (UNIGE) ...
Phys.org / Watching how molecules change shape in slow motion could inform future molecular machines
Researchers at the Nano Life Science Institute (WPI-NanoLSI) at Kanazawa University, the Institute for Molecular Science and SOKENDAI have uncovered the hidden mechanism behind a molecular switch—a molecule that can change ...
Phys.org / EV-SELEX speeds GPCR drug discovery by capturing receptor-bound DNA aptamers
G protein-coupled receptors (GPCRs) are the most abundantly expressed proteins in the human body, regulating diverse physiological processes ranging from pain perception to hormone signaling. Owing to their central roles ...
Phys.org / Paleontologists make 'one in a million' discovery of soft tissue preserved in 450-million-year-old fossil
Before the oldest dinosaur, before animals or even plants had expanded onto dry land, ancient relatives of starfish called crinoids, resembling stalked sea flowers, were among the first creatures to flourish in Earth's earliest ...
Phys.org / Larger brain, smaller face: Human evolution took a different course than previously thought
A new study, published July 6, 2026, in the journal Nature Communications, suggests that two of the best-known trends in human evolution—brain growth and the reduction in the size of the face and jaw—may be far less attributable ...
Phys.org / Cave finds reveal modern humans and Neanderthals may have shared long-term cultural continuity
Tens of thousands of years ago, Homo sapiens coexisted with Neanderthals, Homo neanderthalensis. Many of us living today carry a small amount of Neanderthal DNA, indicating that the two species may have shared much more than ...
Phys.org / Early parenting shapes the brain and socio-sexual behavior, rodent study shows
Past psychology studies have consistently highlighted the importance of social bonds for survival, showing that enduring relationships are linked with a longer life expectancy, a more resilient immune system, better cardiovascular ...
Phys.org / Ancient hobbit-like humans may have survived on meat left behind by Komodo dragons
Arguably one of the most curious ancient human relatives is Homo floresiensis, a 3-foot-tall species that lived on the Indonesian island of Flores and has been nicknamed "hobbit" for its diminutive stature. Even though they ...
Phys.org / Chemists capture structure of the elusive borylnitrene trapped in a crystal using X-ray
Nitrenes are the ghosts of synthetic chemistry, formed in an instant and gone just as quickly, rearranging into something entirely different. These highly reactive intermediates are widely used in synthesis, yet remain notoriously ...
Phys.org / First synthetic protein motor moves along DNA in controlled, programmable steps
Researchers from UNSW Sydney have built the first artificial protein motor capable of taking controlled, directional steps along a DNA track. The protein, dubbed Tumbleweed, moves by alternating between three "feet" that ...
Phys.org / Traces of Earth's primordial magma ocean discovered in lava from a modern volcanic eruption
In May 2018, the island of Mayotte, between Madagascar and Mozambique, began to experience a series of earthquakes that led to the discovery of an underwater volcano, now called Fani Maoré. Multiple scientific expeditions ...
