Optical-resolution photoacoustic microscopy (OR-PAM), a new hybrid imaging technique, allows us to listen to the sound of light and see the color of biological tissue itself. It can be used for live, multicontrast functional imaging, but the limited wavelength choice of most commercial lasers and the limitations of the existing scanning methods have meant that OR-PAM can obtain only one or two different types of contrast in a single scan. These limitations have made multicontrast functional imaging time-consuming, and it s been difficult to capture the dynamic changes of functional information in biological tissues.

The International Society for Stem Cell Research (ISSCR) is launching a new three-part digital series on Computational Stem Cell Biology starting 15 March, 2021. This series is part of the Society s growing portfolio of topic-specific digital scientific programming for members - also offered to non-members for fee. All ISSCR Digital programs are available live and on-demand.
This series explores the groundbreaking advances in RNA- and DNA-sequencing and bioinformatic technologies that have presented stem cell biologists with new insights into complex biological, developmental, and disease processes. This programming focuses on the latest developments in this rapidly advancing field.
Part 1: Exploring Stem Cells with Single Cell and Combinatorial Analyses

LOWELL, Mass. - The U.S. Department of Energy has awarded UMass Lowell researchers $1.8 million to develop recyclable plastics and manufacturing technologies to help the country reduce its greenhouse-gas emissions and improve its environmental sustainability.
The grant is funded through the REMADE Institute, a public-private partnership created by the DOE to help the U.S. move toward what s known as a circular economy, in which waste is eliminated as much as possible by continually reusing and recycling resources.
The UMass Lowell project will seek ways to improve the recycling of plastic films from industrial and consumer goods that typically end up in landfills. The research aims to create new uses for the plastic waste and possibilities for the re-manufacturing of sustainable products. Innovative plastics-processing technologies developed by the researchers and industrial partners would create new opportunities for manufacturers across the country, according to UM

If you were given ultrasound in a word association game, sound wave might easily come to mind. But in recent years, a new term has surfaced: bubbles. Those ephemeral, globular shapes are proving useful in improving medical imaging, disease detection and targeted drug delivery. There s just one glitch: bubbles fizzle out soon after injection into the bloodstream.
Now, after 10 years work, a multidisciplinary research team has built a better bubble. Their new formulations have resulted in nanoscale bubbles with customizable outer shells so small and durable that they can travel to and penetrate some of the most inaccessible areas in the human body.
