Titan Powers Data Dive into Tropical Soil Microbes

Using high-performance computing, an Oak Ridge National Laboratory-led research team analyzed how the availability of phosphorous affects microbes’ foraging strategies in a tropical ecosystem. At right, microbial genes encode the production of phytase enzymes that break apart phytate molecules, releasing much needed phosphate for the microbes’ survival. Every life-form depends…

A Shortcut to Modeling Sickle Cell Disease

https://vimeo.com/251490525 Each year, 500,000 babies are born with a genetic disorder called sickle cell disease, a chronic illness that causes patients’ red blood cells to be abnormally shaped and to stick to the walls of blood vessels. The disorder can cause blockages, debilitating pain, and even damage to the body’s…

Scaling Deep Learning for Science

Deep neural networks—a form of artificial intelligence—have demonstrated mastery of tasks once thought uniquely human. Their triumphs have ranged from identifying animals in images, to recognizing human speech, to winning complex strategy games, among other successes. Now, researchers are eager to apply this computational technique—commonly referred to as deep learning—to…

Assembling Life’s Molecular Motor

Despite the grand diversity among living organisms, the molecule used to store and transmit energy within aerobic, or oxygen-using, cells is remarkably the same. From bacteria to fungi, plants, and animals, adenosine triphosphate (ATP) serves as the universal energy currency of life, fueling the processes cells need to survive and…

Predictive Power

Few jobs are more massive than that of building a nuclear power plant, a project that takes years and billions of dollars to complete. But once a new plant is finished, how do engineers know it will operate as designed? In October 2016, the Tennessee Valley Authority (TVA) began full…

A Seismic Mapping Milestone

Because of Earth’s layered composition, scientists have often compared the basic arrangement of its interior to that of an onion. There’s the familiar thin crust of continents and ocean floors; the thick mantle of hot, semisolid rock; the molten metal outer core; and the solid iron inner core. But unlike…
