Phys.org / From mother to offspring: Young birds show how 'forever chemicals' accumulate
New research has found young birds living near contaminated industrial and military sites in suburban Melbourne carry especially high concentrations of PFAS, so-called "forever chemicals."
Phys.org / AI faces trusted more than faces of real people, warn researchers
Images of faces created by artificial intelligence (AI) are seen as more trustworthy than images of genuine faces, researchers say, warning of the risks of online fraud and other harms. This is the first study to examine ...
Phys.org / Wolves around the world have evolved different skull shapes—humans are also shaping their evolution
A new international study led by researchers at the University of Oulu, Finland, shows that wolves living in different parts of the world are not anatomically identical. Their skulls differ in shape and size according to ...
Phys.org / Birds' efficient red blood cells convert metabolic 'waste' into fuel for rapid recovery
New research finds that birds can use lactate, often thought of as a metabolic waste product, as a cellular fuel that aids in rapid recovery from a harmful state that impairs oxygen delivery. Hemoglobin, the protein that ...
Phys.org / Inferring multicellular interactions in tumors from standard pathology slides
Understanding how cells within and around a tumor interact provides key information about a cancer's architecture, a patient's immune response to the disease and even how susceptible the cancer may be to various types of ...
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 / Raptorial insect forelegs evolved repeatedly but never converged on one winning design
The evolutionary paths that created snatching forelimbs in insects multiple times moved in a similar direction but didn't end at a single solution. Kobe University research is pioneering a study of how organs with similar ...
Phys.org / Bacteria discovered with the ability to jettison cells as a survival mechanism
Popular science fiction is no stranger to escape-pod scenarios, typically featuring characters who narrowly avoid their demise by jettisoning from a spaceship—think R2-D2 and C-3PO shooting away from a rebel spaceship in ...
Phys.org / Bulk ferromagnetic quasicrystals emerge without rapid quenching, unlocking stable magnetic studies
Ferromagnetism has long been studied in a wide range of periodic crystals and amorphous materials. In quasicrystals (QCs), which possess long-range quasiperiodic order and unconventional rotational symmetries, such as 10-fold ...
Phys.org / New biobased polymers exhibit excellent tensile properties beyond polyolefins
The research group of Professor Kotohiro Nomura, Tokyo Metropolitan University, in cooperation with the research groups of Senior Researcher Hiroshi Hirano and Director Seiji Higashi of the Osaka Research Institute of Industrial ...
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 / 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, ...
