You've probably heard a bit about ultra-processed foods by now, and if so, you likely know they're not the healthiest things you can eat. These industrially manufactured foods are increasingly being linked to heightened risk of disease, and research suggests they may affect how we think and harm our mental health. In light of all the concerning associations scientists are finding, it's easy to assume that ultra-processed foods are unhealthy because they're packed full of nutritionally poor ingredients – but what if there's more to it than that? "We know that the majority of ultra-processed foods are high in fat, they're high in sugar, they're low in fiber, and they're low in protein," says neuroscientist Alex DiFeliceantonio from Virginia Tech. "But if we artificially hold all of those things constant, is there something about the processing that leads to a different outcome? "The answer, it seems, is yes, according to a surprising finding reported in Nature Metabolism. Ultra-processed foods seem to produce a different metabolic response, even when nutrients and calories are matched.

The age of exoplanet science took shape with the Kepler mission, and gained more momentum with the TESS mission. The initial goal had a simple definition: use the transit method to find planets orbiting other stars. Beyond that, scientists have worked hard and used multiple tools at their disposal to determine exoplanet compositions and other characterstics. Now exoplanet science is advancing beyond these initial stages. Planetary scientists want to understand not only the wide diversity in the exoplanet population; they also want to understand the different types of solar systems they're detecting.
