Analysis of a volcanic ash tuff layer, only a few millimeters thick and discovered during excavations in 2024, revealed that the fossil-bearing Bromacker rocks are 294 million years old—four million years older than previously ...
Phys.org / Friendly fungi hijack plant regulator to promote symbiosis
Plants are constantly on guard. Their roots are equipped with molecular alarm systems that detect invading microbes and trigger immune responses. Yet beneficial soil fungi routinely enter living root cells and establish close ...
Phys.org / Asymmetric spin torque unlocks deterministic control of antiferromagnetic memory
A research team led by Prof. Shao Dingfu from the Hefei Institutes of Physical Science, Chinese Academy of Sciences, has proposed a universal mechanism that enables deterministic electrical control of collinear antiferromagnets—overcoming ...
Medical Xpress / Why street layouts may matter for aging brains: Brain scans link walkability to memory
The simple act of crossing a road could help shield the brain from dementia and other cognitive conditions, according to new research from the Australian Catholic University and UNSW Sydney's Center for Healthy Brain Aging ...
Phys.org / What primate faces reveal about empathy: Humans mirror emotions across species
Humans perceive emotional expressions displayed by non-human primates and spontaneously mimic these expressions, according to a study published in the open-access journal PLOS One by Ursula Hess from Humboldt University of ...
