Phys.org / World's oldest juniper shrub discovered in Finland—annual rings suggest it's 1,647 years old
Researchers from the University of Padua in Italy found a juniper at Utsjoki in Finnish Lapland, which they analyzed to be 1,647 years old by examining the annual rings. The paper is published in the journal Ecology.
Phys.org / Implanted medical devices coated with copper nanoparticles could reduce infection risk
Scientists have developed copper oxide nanoparticles which can be coated onto implanted medical devices to reduce the risk of infection after operations. A team at Nottingham Trent University has led the work, which it is ...
Phys.org / Contamination detection tool merges synthetic biology and nanotech for ultrasensitive water testing
A platform developed nearly 20 years ago previously used to detect protein interactions with DNA and conduct accurate COVID-19 testing has been repurposed to create a highly sensitive water contamination detection tool.
Phys.org / Xolography-based method enables 3D printing of living tissues with light
Xolography is a novel light printing technique that has been explored for dental products and in-space manufacturing. At Eindhoven University of Technology (TU/e), this technique has now been adapted to 3D print living cells. ...
Phys.org / How did life develop on early Earth? New source of nitrogen discovered
Living organisms need nitrogen as a central building block for protein formation, for example. However, although our atmosphere contains plenty of nitrogen, neither humans nor the vast majority of plants can absorb it directly ...
Phys.org / Artificial photosynthesis converts organic waste into useful pharmaceuticals and energy
A research team led by Assistant Professor Shogo Mori and Professor Susumu Saito at Nagoya University has developed a method of artificial photosynthesis that uses sunlight and water to produce energy and valuable organic ...
Phys.org / Computer vision system tracks plant growth to guide specialty crop monitoring
Soilless growing systems inside greenhouses, known as controlled environment agriculture, promise to advance the year-round production of high-quality specialty crops, according to an interdisciplinary research team at Penn ...
Phys.org / Utah dig site reveals increased diversity of fossilized eggshells
A team of biological, Earth and environmental scientists from North Carolina State University, Stellenbosch University and the University of Minnesota has found new types of ancient eggshells in the Mussentuchit Member in ...
Phys.org / Optimized approach enables super-resolution 3D direct laser writing with unprecedented speed and resolution
For the first time, researchers have used high-speed laser writing to create lines spaced just 100 nm apart on a glass substrate. The optimized printing approach could enable super-resolution 3D direct laser writing (DLW) ...
Phys.org / Weak rocks and melting ice sheet explain rapid ground uplift in Southeast Greenland
The coastline of Southeast Greenland is uplifting more rapidly than other parts of the island. This is caused by weak rocks beneath this part of Greenland, combined with the melting of the ice sheet, according to researchers.
Phys.org / Solar energy has become politically polarized, social media reveals
A new analysis of social media posts finds public support for solar energy remains high, though that support declined significantly from 2016 to 2022. The study also found solar power has become an increasingly polarized ...
Phys.org / Next-generation organic nanozymes offer safe, cost-effective solution for agricultural and food industries
Nanozymes are synthetic materials that have enzyme-like catalytic properties, and they are broadly used for biomedical purposes, such as disease diagnostics. However, inorganic nanozymes are generally toxic, expensive, and ...
