Phys.org / Single-celled organisms have more complex DNA epigenetic code than multicellular life, researchers discover
Multicellular organisms (animals, plants, humans) all have the ability to methylate the cytosine base in their DNA. This process, a type of epigenetic modification, plays an important role in conditions such as cancer and ...
Tech Xplore / Google unveils Gemini 3, aiming to turn its search engine into a 'thought partner'
Google is unleashing its Gemini 3 artificial intelligence model on its dominant search engine and other popular online services in the high-stakes battle to create technology that people can trust to enlighten them and manage ...
Phys.org / How a genetic circuit may have helped the evolution of insect wings
In most developing tissues, signals called morphogens act like lighthouses, guiding nearby cells toward their fate and telling them what to become. Each cell relies on such signals for organized structures like organs and ...
Phys.org / Chiral skyrmion flows enable new approach to nanoscale logic devices
In magnetic materials with antisymmetric exchange interactions, novel particle-like spin textures called magnetic skyrmions can appear and be manipulated by electrons. First observed in 2009, they have been created and controlled ...
Phys.org / Machine learning framework can scan for signs of extraterrestrial life
A machine learning framework can distinguish molecules made by biological processes from those formed through non-biological processes and could be used to analyze samples returned by current and future planetary missions. ...
Phys.org / Nanoparticles promise swift Vibrio control for safer seafood and healthier fish
Vibrio bacteria are major pathogens in the aquaculture industry, triggering vibriosis—a disease that can cause mortality rates of up to 90% within two days. This not only results in billions of dollars in economic losses ...
Phys.org / Supercomputer simulates quantum chip in unprecedented detail
A broad association of researchers from across Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley have collaborated to perform an unprecedented simulation of a quantum microchip, ...
Medical Xpress / Chronic lymphocytic leukemia: New origins and biomarkers revealed
Researchers at the University of Eastern Finland and their international collaborators have identified key developmental and molecular differences between the two main subtypes of chronic lymphocytic leukemia, CLL. The findings, ...
Phys.org / The genome editing playbook is different in neurons and other nondividing cells, researchers discover
The gene editing tool known as CRISPR-Cas9 is changing what's possible for treating a wide range of diseases caused by genetic mutations. But so far, attempts to use the technology to address brain-based genetic disorders ...
Medical Xpress / Heavy cannabis use during pregnancy linked to disruption in brain growth
McGill University researchers at the Douglas Research Center have found evidence that heavy cannabis use during pregnancy can cause delays in brain development in the fetus that persist into adulthood.
Phys.org / Illuminating the messages that cells leave behind: Cells trek along vesicle 'breadcrumbs'
In stunning new time-lapse videos, biological nanoparticles scoot and flit across a starry field of glowing dots. Guided by the invisible chemistry of attraction, these microscopic travelers eventually group together to form ...
Medical Xpress / AI can improve mental health questionnaires by detecting overlaps and redundancies
Large language models can help improve questionnaires used to diagnose mental illness by optimizing symptom generalizability and reducing redundancy. They can even contribute to new conceptualizations of mental disorders. ...
