phys.orgProminent academics call for more science in forensic scienceWith forensic science facing mounting scrutiny as it plays an increasingly prominent role in the administration of justice, six scientists who recently served on the National Commission on Forensic Science are calling on the scientific community at large to advocate for increased research and financial support of forensic science as well as the introduction of empirical testing requirements to ensure the validity of outcomes. Their call to action appeared in the Proceedings of the National Academy of Sciences (PNAS) the week of April 9, 2018.

The opinions contained within guest posts are those of the authors and do not necessarily reflect the official opinion of The Edvocate or Dr. Matthew Lynch.** A guest post by Anwar Dunbar Every Black History Month there are numerous African American scientists and innovators who are typically celebrated in Science (Technology, Engineering and Mathematics (STEM). It’s worth noting, however, that there are also quite few African American scientists in modern times that are worth recognizing. One such scientist is …
phys.orgRings and gaps in a developing planetary systemThe discovery of an exoplanet has most often resulted from the monitoring of a star's flicker (the transiting method) or its wobble (the radial velocity method). Discovery by direct imaging is rare because it is so difficult to spot a faint exoplanet hidden in the glare of its host star. The advent of the new generation of radio interferometers (as well as improvements in near-infrared imaging), however, has enabled the imaging of protoplanetary discs and, in the disc substructures, the inference of orbiting exoplanets. Gaps and ring-like structures are particularly fascinating clues to the presence or ongoing formation of planets.
