Medical Xpress / Newly discovered virus linked to colorectal cancer
Colorectal cancer is one of the most common types of cancer in the Western world and a leading cause of cancer-related deaths. Age, diet and lifestyle are known risk factors. However, in most cases we still lack a precise ...
Phys.org / Giant DNA viruses encode their own eukaryote-like translation machinery, researchers discover
In a new study, published in Cell, researchers describe a newfound mechanism for creating proteins in a giant DNA virus, comparable to a mechanism in eukaryotic cells. The finding challenges the dogma that viruses lack protein ...
Phys.org / The Princess of Bagicz: Dendrochronology settles debate over age of rare Roman-era wooden coffin
Dr. Marta Chmiel-Chrzanowska and her colleagues conducted a multidisciplinary analysis of the only known preserved wooden coffin from the Roman Iron Age, the Princess of Bagicz. The study, published in Archaeometry, used ...
Phys.org / New chip-scale microcomb uses lithium niobate to generate evenly spaced light
Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have discovered a new way to generate ultra-precise, evenly spaced "combs" of laser light on a photonic chip, a breakthrough ...
Phys.org / Cheaper green hydrogen? New catalyst design cuts energy losses in AEM electrolyzers
Producing clean hydrogen from water is often compared to storing renewable energy in chemical form, but improving the efficiency of that process remains a scientific challenge. Researchers at Tohoku University have now developed ...
Phys.org / A 'magic blueprint' for converting CO₂ into resources through atom-level catalyst design
A research team led by Professor Su-Il In of the Department of Energy Science and Engineering at DGIST has uncovered the principle that the products and reaction pathways of carbon dioxide (CO2) conversion to fuel via solar ...
Phys.org / Nature-inspired method forms ZnO quantum dots in solid crystals at room temperature
In nature, tiny crystals known as nanocrystals are formed slowly over many years. Rocks and minerals react with air, water, and carbon dioxide in a process called chemical weathering. These reactions happen gently, at room ...
Phys.org / Obstacle or accelerator? How imperfections affect material strength
Imagine a material cracking—now imagine what happens if there are small inclusions in the material. Do they create an obstacle course for the crack to navigate, slowing it down? Or do they act as weak points, helping the ...
Phys.org / Scientists unlock a massive new 'color palette' for biomedical research by synthesizing non-natural amino acids
Ozempic has been making headlines for its remarkable success in treating obesity and diabetes. Yet it is just one in a rapidly growing class of drugs called peptide therapeutics that sits between small molecules (like aspirin) ...
Phys.org / A key out-of-Africa site just got older: Dating methods push 'Ubeidiya site back at least 1.9 million years
A new study provides a clearer timeline for one of the most significant prehistoric sites worldwide for the study of human evolution. By integrating three advanced dating techniques, researchers have determined that the site ...
Phys.org / Study links 'dark pool' trading to higher risk of sudden stock price crashes
More stock trading is moving away from traditional public stock exchanges and into places called "dark pools." These are private, electronic markets where investors buy and sell stocks without showing their orders to the ...
Medical Xpress / Fiber-free processed foods hit emotional memory fast, especially in older brains
Past studies in animals have shown that a highly processed diet is linked to memory problems and inflammation in the aged brain—and the effect can happen fast, after just three days of poor eating.
