Microscopy in the body

Biotechnologists and medical researchers at FAU have developed a miniaturized multi-photon microscope that can be used in endoscopes, illuminating the body's own molecules to enhance imaging. This technology offers high-resolution three-dimensional images of living tissue, supplementing or even making biopsies superfluous.

'Lovely' and 'scientific' -- Medical student evaluations differ by gender and minority status

Student teams use O.R. and analytics to help GM introduce new autonomous vehicles to fleet

In the INFORMS O.R. & Analytics Student Team Competition, student teams from around the world used operations research (OR) and analytics to optimize autonomous vehicle delivery processes for General Motors. The winning team from Korea Advanced Institute of Science and Technology minimized total costs while satisfying all constraints.

Study finds natural variation in sex ratios at birth and sex ratio inflation in 12 countries

A new estimation method for assessing natural variations in the sex ratio at birth was developed by an international team of researchers. The study found regional baseline SRB imbalances and identified 12 countries with strong evidence of sex ratio inflation, leading to fewer female births than expected.
