A prototype microscope that uses neutrons instead of light to "see" magnified images

A prototype microscope that uses neutrons instead of light to "see" magnified images has been demonstrated at the National Institute of Standards and Technology. Neutron microscopes might eventually offer certain advantages over optical, X-ray and electron imaging techniques such as better contrast for biological samples.

Miniature spectroscopic instruments and software to look at changes that occur within the cells and tissue of the brain

When molecules in cells are stimulated by light, they respond by becoming excited and re-emitting light of varying colors (fluorescence) that can be captured and measured by highly sensitive optical equipment.

Light-sensitive probe to help doctors spot breast cancer

A light-sensitive probe is being developed to help doctors spot breast cancer in some of the 70,000 American women each year whose malignancies fail to show up in needle biopsies.

New technology acts as third eye during breast biopsies

Doctors currently use X-ray or ultrasound - two-dimensional pictures - to guide the biopsy needle into a three-dimensional region. To ensure that they are doing the biopsy at the right spot, they take up to a dozen tissue samples.

Positron emission tomography offers a better way to observe the damage that strokes and neurodegenerative diseases wreak on brain cells

A laser-based microscopy technique may have settled a long-standing debate among neuroscientists about how brain cells process energy

Pulsed dye laser therapy not effective in treating acne

Unfortunately, there also appears to be no benefit, at least with one type of laser treatment called pulsed dye laser therapy, according to new research from the University of Michigan Health System.

Positive benefits of sun exposure

There is no getting around the fact that sunlight is hard on your skin. But what about the positive benefits of sun exposure? The June Harvard Health Letter discusses the good and the bad of the sun.

3-D micro-imaging technology licensed to Carl Zeiss Jena by Cornell

Biomedical microscopic imaging deep inside living tissue with unprecedented clarity could become routine and widely available with the signing of technology-transfer and collaborative-research agreements today (May 28, 2004) by Carl Zeiss Jena GmbH, a leading maker of microscopy instrumentation, and by CCTEC, the technology, enterprise and commercialization arm of Cornell University.

New optical glucose sensor could mean help for diabetics

Researchers at the University of California, Santa Cruz, have developed a novel optical glucose sensor that could be used to provide continuous monitoring of glucose levels in diabetics and hospitalized patients. Recently published studies showed that the sensor detects glucose under physiological conditions, giving a reversible fluorescent signal that changes intensity in response to changes in the concentration of glucose.
