Using a simple 'mirror trick' and not-so-simple computational analysis, scientists affiliated with the Marine Biological Laboratory (MBL) have considerably improved the speed, efficiency, and resolution of a light-sheet microscope, with broad applications for enhanced imaging of live cells and embryos.
In recent years, optics and photonics, and in particular the microspectroscopic techniques, have demonstrated their effectiveness for the materials analysis. The work 'Non-contact mechanical and chemical analysis of single living cells by micro-spectroscopic techniques' which will appear in the journal Nature-Light: Science & Applications (LSA), introduces the use of a new spectrometer capable of analysing living cells in situ, in non-invasive manner and with sub-micrometric spatial resolution.
Is it going to be possible to detect features of autism at birth? At the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw a sensor has come into being that means this may become a reality. The main recognition component of the new device is a polymer layer with a carefully designed structure. It recognizes molecules of oxytocin, a compound considered to be one of the biomarkers of autism.
As any wine enthusiast knows, the 'legs' that run down a glass after a gentle swirl of vino can yield clues about alcohol content. Interestingly, the physical phenomenon that helps create these legs can be harnessed to propel tiny motors to carry out tasks on the surface of water. Scientists demonstrate the motors in a report in ACS' journal Langmuir.
A new study has revealed a chain mail-like woven microstructure that gives parrotfish teeth their remarkable ability to chomp on coral all day long - the structure could serve as a blueprint for designing ultra-durable synthetic materials.
Study shows that reefs built to reach a foot or more above the bottom develop into healthy, self-sustaining ecosystems, while those rebuilt at lower heights are quickly buried by sediment.
Lobachevsky University scientists under the supervision of Alexey Mikhailov, Head of the UNN PTRI Laboratory of Thin Film Physics and Technology, are working to develop an adaptive neural interface that combines, on the one hand, a living culture, and on the other, a neural network based on memristors. This project is one if the first attempts to combine living biological culture with a bio-like neural network based on memristors.
Researchers at Kanazawa University and the University of Tokyo report in Nature Communications the visualization of the dynamics of 'molecular scissors' -- the main mechanism of the CRISPR-Cas9 genetic-engineering technique.
ETH researchers have reprogrammed normal human cells to create designer immune cells capable of detecting and destroying cancer cells.
In an article published in Nature Communications, researchers at the University of California, Riverside and the University of Pennsylvania School of Medicine used high-powered microscopy and rheometry -- the measurement of how materials become deformed in response to applied force -- to view the blood clotting process in real time and at the cellular level. The findings will be useful in the development of new therapies for clotting disorders.
