A team of researchers has developed a reproducible and scalable method for producing graphene oxide (GO) nanosheets from commercial carbon fibres, marking a breakthrough in sustainable nanomaterial synthesis. The process involves exfoliating carbon fibres with nitric acid, which provides high yields of one-atom-thick sheets of graphene oxide with characteristics comparable to commercial GO sourced from […]
In the previous entry I introduced my definition of a concept of empirical verisimilitude of a proposition H given the evidence E (or how close to the truth H seems under the light of data E), Vs(H,E) , as the combination of the similarity or coherence between H and E, and that between E and […]
How did the brain of Vesuvius victim turn into glass? A victim of the Vesuvius volcano eruption in 79 CE experienced a unique condition when his brain turned into glass. Researchers determined that the brain was subjected to temperatures over 510 degrees Celsius, followed by rapid cooling that kept “the ultra-fine neural structure of the […]
Superconductivity, the phenomenon where electrical current flows without resistance, has long captivated scientists and engineers. This unique state of matter holds promise for revolutionizing technologies, from power grids to magnetic levitation. A recent study delves into the intriguing world of graphene-based superconductors, shedding light on how twisting multiple layers of graphene can influence their superconducting […]
You have probably heard the saying that the eyes are the windows to the soul, but now it turns out that they are also connected to how we breathe. Scientists have long studied the size of our pupils to understand attention, emotion and even medical conditions. But now, new research has surprisingly revealed that they […]
In a leap forward for quantum computing, a Microsoft team led by UC Santa Barbara physicists on Wednesday unveiled an eight-qubit topological quantum processor, the first of its kind. The chip, built as a proof-of-concept for the scientists’ design, opens the door to the development of the long-awaited topological quantum computer. “We’ve got a bunch […]
Author: José R. Pineda got his Ph.D. from University of Barcelona in 2006. Since 2007 he has worked for Institut Curie and The French Alternative Energies and Atomic Energy Commission. Currently he is a researcher of the UPV/EHU. He investigates the role of stem cells in physiologic and pathologic conditions. Schizophrenia is a chronic and […]
Orchids deploy parasitism to boost growth New research on the orchid species Oreorchis patens reveals that these plants can switch to parasitism by extracting nutrients from fungi near decomposing wood, without abandoning photosynthesis. This dual strategy allows the orchids to grow larger and produce more flowers. Full Story: Popular Science Permafrost thaw alters size of […]
Hydrogels are fascinating materials that can absorb and retain large amounts of water, making them useful in various fields such as medicine, environmental science, and engineering. A recent study has explored a new type of hydrogels made from cellulose nanofibres (CNFs) and lignocellulose nanofibres (LCNFs), aiming to enhance their strength and water-absorbing capabilities. Cellulose and […]
The ability to uptake cellular debris and process the engulfed antigens for MHC class I presentation is mainly performed by a minority subset of dendritic cells . Immunologists identified them as “conventional-type 1 dendritic cells”, and characterized them identifying the presence of surface coexpression of CD11c, XCR1, and DNGR-1 molecules . In mice, two subsets […]
