Phys.org / A 100-year-old mystery in the cat kidney may be linked to scent communication
Many animals obtain information about others from scent marks left in the environment, including urine. Because these marks remain after the sender has left, they allow animals to communicate across space and time. But odor ...
Phys.org / Greenwashing firms are scrutinized less if they are in politicians' pockets, study finds
Companies with strong political connections are more likely to escape scrutiny over greenwashing, according to new research from Durham University Business School. Greenwashing occurs when organizations overstate or misrepresent ...
Phys.org / Jellyfish reveal how rapid cell turnover may suppress early cancer growth
Although increased cell proliferation is a hallmark of cancerous tissues, in some cases it may actually protect against tumor growth, according to a new study by Caltech researchers. Using mathematical models, the work suggests ...
Phys.org / Metastable 3D printing 'ink' enables a closed-loop material cycle
Polymers used for light-based 3D printing are very stable because of their chemical structure, but they are typically hard to recycle. A research team led by Professor Dr. Eva Blasco, a researcher at the Institute for Molecular ...
Phys.org / Antarctica's brief rebound was caused by climate variability, not a 'new normal'
Between 2021 and 2023, Antarctica appeared to be growing. Heavy snowfall fueled by wetter weather caused parts of the continent to gain mass, leading some to question whether climate change is really causing the ice to melt. ...
Phys.org / Peru's highest mountain confirms tropics were a major methane source before the industrial era
A new analysis of ice cores collected from the Andes in Peru has produced the first global record of historical tropical methane, filling a critical gap in our understanding of the origins of Earth's greenhouse gases.
Phys.org / New lipid nanoparticle delivers capped circular RNA for longer-lasting gene expression
Researchers at Nagoya University in Japan in collaboration with FUJIFILM have developed a novel way of delivering circular RNA (cirRNA) into cells, paving the way for longer-lasting mRNA-based therapeutics including cancer ...
Phys.org / Reusing liquid pickle waste to produce omega-3 fatty acids
Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are omega-3 fatty acids known to have beneficial effects and are popular as functional foods and dietary supplements. They are polyunsaturated fatty acids (PUFAs); ...
Phys.org / Neutron capture experiment sheds light on ancient stardust
Niobium-94, an isotope of niobium with 41 protons and 53 neutrons, is a critical crossroads in the complex nuclear processes that forge heavy elements under the intense pressures and temperatures of dying stars. In an article ...
Phys.org / Quantum simulators gain quantitative error bars in 51-ion test
In the coming years, increasingly larger and more powerful quantum systems are expected to tackle problems that are difficult or impossible to solve using conventional computers. However, the more powerful quantum simulations ...
Phys.org / Archaeologists unveil skeletal remains believed to be ritual offering in Peru
Archaeologists on Tuesday unveiled the skeletal remains of an adult they believe was buried as an offering near the base of Huaca Pucllana, an ancient adobe pyramid in Peru's capital of Lima.
Phys.org / Lost 'mega-escarpment' across ancient USA may explain Grand Canyon's missing billion years
Scientists have found evidence that a colossal cliff stretching thousands of kilometers across ancient North America may have exposed the heart of the Grand Canyon nearly a billion years before it was carved by the Colorado ...
