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 / 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 / AI flood map reveals 11 million Americans may be omitted from official risk zones
Official flood maps shape disaster preparedness, insurance decisions and urban planning, but large parts of the United States remain unmapped or under-mapped. This means some communities may be left unaware of the risks they ...
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 / 3D map of cell signaling sites could help improve cancer treatment
Cell-communication molecules called kinases play a key role in the growth and spread of many cancers. But exactly which kinases are active in a particular cancer is not always clear—there are 1.8 million sites on human proteins ...
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 / Novel insights into aerosol behavior could improve air-quality forecasting
New research from Purdue University demonstrates how organic aerosol molecules can influence one another's behavior in ways that existing atmospheric models do not fully capture.
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 / Foldamer–protein pair unlocks precise building blocks for artificial molecular materials
Proteins form complex three-dimensional shapes and can join together to create larger structures. Researchers want to use these properties to make artificial materials. However, arranging proteins and synthetic molecules ...
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 / 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 ...
