While the brain is vastly complex, there is still much more to explore and understand about this organ and neurodegenerative diseases that can occur. The adequate flow of blood to and from the brain is vital for the proper functioning of our bodies and minds. Via a network of capillary vessels in our bodies, tissues and organs (including the brain) are supplied with oxygen and nutrients. But when blood flow is blocked for any reason, such as a building up of white blood cells, certain neurodegenerative diseases can seem to simultaneously arise. Could reduced blood flow play a role in the onset of these diseases? At the Meinig School of Biomedical Engineering at Cornell University, Oliver Bracko, PhD student Nancy Ruiz and colleagues investigate the important role that brain blood…

Science illustration is vital in medical fields to help medical students and staff continually learn and conceive of medical concepts. Quality medical illustrations support doctors and medical researchers with their life-saving work. Pursuing a career as a medical illustrator can be deeply challenging, collaborative and stimulating within an institution. This is particularly the case for Peter M. Lawrence who is working as a medical illustrator at the Barrow Neurological Institute. Having a background in fine art, his illustrative skills are continually cultivated here while working alongside surgeons to create accurate and educational medical art.

Protecting reefs is becoming increasingly important for regions like the southern Gulf of Mexico where tourism and population is rising. In the past, at first glance, isolated reefs in particular seemed to be relatively safe from the harmful impacts of man-made industry, being cut-off compared to other reef systems. However, in recent times, is this still the case, particularly in areas that have been unprotected? Fabio Favoretto is a marine ecologist who conducted ecological research at isolated reefs off the coast of the southern Gulf of Mexico. The research team went diving with underwater measurement tools, counting and measuring the marine life in isolated reefs. Some isolated reefs are protected from the dangers of overfishing, however some are not. Fabio and the research team made some striking discoveries about how…

For centuries, philosophers and scholars have wondered if the stars in the night sky might have their own planets. And yet, it has only been in the past few decades that astronomers have been able to find any extrasolar planets (aka. exoplanets). In fact, it wasn’t until 1992 that the first two exoplanets were officially confirmed orbiting a pulsar (PSR B1257+12) 2,300 light-years away. Since then, thousands of exoplanets have been detected and confirmed, most of them in just the past decade. All of this is due to a combination of technological advancements, refinements in exoplanet-hunting methods, and improved coordination between observatories worldwide. In the coming years, we can expect many more discoveries as new observatories become operational, space telescopes are launched, and machine learning and citizen scientists get better…
