Solar evaporator offers a fresh route to fresh water

Researchers at the University of Maryland have developed a self-cleaning solar evaporator made of wood that can efficiently produce clean drinking water from salty water. The device uses interfacial evaporation technology and minimizes maintenance needs, making it suitable for off-grid water generation in low-income countries.

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

Researchers analyzed over 90,000 narrative medical school evaluations, finding significant differences in how female and underrepresented minority students are described. Evaluators often used personal descriptors to describe performance, with strikingly different words for men and women. The study also identified biases in descriptive...

NASA study verifies global warming trends

A NASA study has verified recent global warming figures, showing high consistency between satellite-based AIRS data and station-based GISTEMP analysis over the past 15 years. The findings also suggest that surface-based data may be underestimating temperature changes in the Arctic, indicating faster warming at the poles.
