Phys.org / Genetic 'switches' could program 3D-printed bone tissue for blood vessel growth
An interdisciplinary team of engineers and chemists at Penn State has laid the groundwork for 3D printing spheroids—tiny clusters of living cells—capable of regenerating bone tissue in response to severe trauma or infections.
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 / Climate taxonomy tool turns risk assessments into practical adaptation guidance
As climate impacts such as heat waves, floods and fires intensify worldwide, there is an urgent demand for information on how to respond. IIASA researchers and partners have developed a new tool that meets that need, integrating ...
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 / 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 / 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 / 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 / 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 / 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 / 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 / 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 / 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.
