Batteries were invented in 1800, but their complex chemical processes are still being explored and improved. While there are several types of batteries, at its essence a battery is a device that converts chemical energy into electric energy.

Cyber resilience, which is also sometimes referred to as cyber resiliency, is the ability to weather adverse events in a computing environment. The National Institute of Standards and Technology (NIST) defines cyber resilience as “the ability to anticipate, withstand, recover from, and adapt to adverse conditions, stresses, attacks, or compromises on systems that use or are enabled by cyber resources.” Cyber resilience applies to both physical and virtual assets.

Americans rely on critical infrastructures to protect the nation, maintain a strong economy, and enhance quality of life. These infrastructures—which include the electrical power grid, transportation systems, information networks, banking and finance systems, manufacturing and distribution, and more—are evolving and modernizing. They have become increasingly complex, connected, and vulnerable to adverse conditions, such as cyber and physical attacks.

Export controls are U.S. laws and regulations that govern the shipment, transmission, or transfer of sensitive equipment, information, and software to foreign countries, persons, or entities. Export controls exist to protect the national security and foreign policy interests of the United States. These laws and regulations work to achieve adequate oversight on the transfer and use of the products and materials required for developing proliferation-sensitive parts of the nuclear fuel cycle.

Bioinformatics uses computers to make sense of the vast amount of data researchers can now glean from living things. These things can be as seemingly simple as a single cell or as complex as the human immune response. Bioinformatics is a tool that helps researchers decipher the human genome, look at the global picture of a biological system, develop new biotechnologies, or perfect new legal and forensic techniques, and it will be used to create the personalized medicine of the future.

Fentanyl analogs are illicit—and often deadly—alterations of the medically prescribed drug fentanyl. The analogs have similar—but not the same—chemical structure, and they mimic the pharmacological effects of the original drug.
