The probe of an atomic force microscope (AFM) scans a surface to reveal details at a resolution 1,000 times greater than that of an optical microscope. That makes AFM the premier tool for analyzing physical features, but it cannot tell scientists anything about chemistry. For that they turn to the mass spectrometer (MS).

Inspired by 1970s method, Stanford scientists find a way to go back and improve past scientific results.

The new experimental assay can help scientists find the precise locations of repair of DNA damage caused by UV radiation and common chemotherapies. The invention could lead to better cancer drugs or improvements in the potency of existing ones.

With Apple's launch of new health tracking tools for the iPhone and medical researchers' forays into Facebook to recruit clinical trial volunteers, Web and mobile apps are increasingly seen as a new source for health data.

Salk Institute findings on premature aging syndrome could lead to way of slowing or reversing aging process.

6 weeks remaining to submit oral papers.

From joy to sadness, facial expressions could soon be decipherable to robots.

In certain types of cancer, nerves and cancer cells enter an often lethal and intricate waltz where cancer cells and nerves move toward one another and eventually engage in such a way that the cancer cells enter the nerves.

The switchgrass exhibited mosaic symptoms—splotchy, discolored leaves—characteristic of a viral infection, yet tested negative for known infections. Deep sequencing, a new technology, revealed the plants were infected with a new virus in the genus mastrevirus, the first of its kind found in North America.

Few Ontarians eat enough dark green and yellow vegetables despite their nutritional benefits, according to a University of Guelph study.
