Microbes play important roles in ecosystems, and these roles are changing with global warming. Scientists also now know that most types of microbes are infected by viruses, but they know relatively little about how these ...

Inside the proton are elementary particles called quarks. Quarks and protons have an intrinsic angular momentum called spin. Spin can point in different directions. When it is perpendicular to the proton's momentum, it is ...

Increasing either temperature or nutrients can hurt ecosystems by destabilizing food webs, which are all of the interconnected food chains that make communities behave the way they do. When temperature and nutrients increase ...

There is so much that we do not yet know about neutrinos. Neutrinos are very light, chargeless, and elusive particles that are involved in a process called beta decay. Understanding this process may reveal the origin of matter ...

An atomic nucleus assumes discrete energy levels when added energy excites that nucleus. These energy levels are the nucleus' unique fingerprint; no two nuclei have identical energy patterns. For exotic nuclei, which have ...
