Blair River was described as “a big guy with a big heart.” The 575-pound former high school wrestler from Mesa, Ariz., became such a fixture at the Heart Attack Grill that he was recruited to be the restaurant’s official spokesperson. His satirical ads made him a minor celebrity in central Arizona. He died in 2011 at age 29 — not because of his heart but from complications of influenza. It was not entirely surprising: Many reports have observed that heavier patients appear more likely to come down with infections during a hospital stay, acquire weaker protection from vaccinations and, as with River, suffer more complications from the flu. Weight alone may not be the entire explanation. A tantalizing line of evidence suggests that unhealthful foods — fatty, salty, sugary, processed foods — may disrupt the body’s defenses in a way that promotes inflammation, infection, autoimmune diseases and even illnesses like cancer.

Future Mars colonists will have a lot of problems to surmount: growing sustainable food, maintaining a steady supply of oxygen, and of course, staving off space cabin fever. But there’s another pressing problem that will affect them before they even land on the Martian surface: space radiation. It’s generally accepted that a long space flight is going to involve some radiation exposure, but just how damaging that radiation would be has been something of a mystery.

Would you run a mild electric current through your head to score better on a chemistry final, or to grind a bit more effectively through Call of Duty? Many folks already are. Preliminary research on the effects of transcranial direct current stimulation, or tDCS, has spurred a host of scientists—and amateurs—to explore the possibility of improving cognitive function, increasing reaction times, and even treating mental illnesses through carefully applied electrodes.

A career in science is hard enough, but stacking motherhood on top of that takes it to another dimension. This Mother’s Day, we’re thinking about all the great moms who are also great scientists, starting with the woman and outstanding scientist who led the way.
