While some existing sensors can monitor the microscopic matter behind these issues, they often have limitations. A primary example is a device known as a field-effect transistor—a tiny component that controls the flow of electrical current in a system—that struggles to remain stable when exposed to liquid. https://phys.org/news/2026-03-graphene-sensors-stay-stable-liquids.html Nanomaterials Tue, 17 Mar 2026 17:10:01 EDT news692981281 At a potluck, you ate the best chocolate chip cookie—golden-brown, thick and chewy. Unfortunately, you don't know who made the cookie to get the recipe from, so you decide to recreate it. Using forward design principles, you might randomly choose a recipe from dozens of options, bake and observe the resulting cookies. If they are too thin, you might start over with a new recipe, add more flour or chill the dough longer and make a new batch. An alternative method is to start from the cookie characteristics you want and ask: What recipe and baking settings will produce that type of cookie? This method is called inverse design. https://phys.org/news/2026-03-inverse-pathway-custom-functional-polymers.html Polymers Tue, 17 Mar 2026 09:00:07 EDT news692956417 The COVID-19 pandemic brought messenger RNA (mRNA) vaccines to the forefront of global health care.
