Metasurfaces: tiny tech with big potential

Metasurfaces, ultra-thin films of nanostructures, hold immense promise for manipulating light with unprecedented control. However, their full potential hinges on overcoming the challenge of crafting these intricate patterns at large scales and high resolutions. This review explores the current nanofabrication techniques, including maskless and masked lithography, exploring their strengths and limitations. By understanding these constraints, we can pave the way for advanced nanophotonic applications powered by these light-bending marvels.

Optical Imager Captures Amplitude and Phase Information without Digital Processing

UCLA researchers introduced an all-optical complex field imager that captures both amplitude and phase information of optical fields using an intensity-based sensor array. This device employs optimized diffractive surfaces to eliminate the need for digital processing in conventional complex imaging techniques, improving imaging speed and reducing computational demand.

NIH launches intramural bioengineering center to foster technology collaboration across the agency

NIBIB has established the Center for Biomedical Engineering Technology Acceleration—BETA Center, a new intramural research program to solve a range of medicine’s most pressing problems. The BETA Center will serve the wider NIH intramural research program as a biotechnology resource and catalyst for NIH research discoveries.

Study finds risk of leukemia higher than expected in children with Down syndrome

The risk of childhood leukemia among kids with Down syndrome is higher than predicted, according to a new study led by UC Davis and UC San Francisco researchers. Early diagnosis remains critical.
