High-Speed Movie Aids Scientists Who Design Glowing Molecules

JellyfishiStock.jpg

In a recent experiment conducted at the Department of Energy’s SLAC National Accelerator Laboratory, a research team used bright, ultrafast X-ray pulses from SLAC’s X-ray free-electron laser to create a high-speed movie of a fluorescent protein in action. With that information, the scientists began to design a marker that switches more easily, a quality that can improve resolution during biological imaging.

Locking Down the Big Bang of Immune Cells

GraphicalAbstract-1.jpg

Scientists have found that ignored pieces of DNA play a critical role in the development of immune cells (T cells). These areas activate a change in the structure of DNA that brings together crucial elements necessary for T cell formation. This “big bang” discovery may aid in combating diseases.

Scientists Sequence Asexual Tiny Worm—Whose Lineage Stretches Back 18 Million Years

FitchGunsalus.jpg

A team of scientists has sequenced, for the first time, a tiny worm that belongs to a group of exclusively asexual species that originated approximately 18 million years ago—making it one of the oldest living lineages of asexual animals known.

Dino-Killing Asteroid's Impact on Bird Evolution

Liliput_Timeline_final.jpeg

Human activities could change the pace of evolution, similar to what occurred 66 million years ago when a giant asteroid wiped out the dinosaurs, leaving modern birds as their only descendants. That's one conclusion drawn by the authors of a new study published in Systematic Biology.

Sensing Their Way to the Future

NAISE_Figure-1Final_900x.jpg

The Northwestern Institute of Science and Engineering this summer offered its inaugural summer research program for 12 undergraduate science and engineering majors. During the 10-week program, the students worked on projects of mutual strategic importance to Argonne and the university in machine learning, environmental sensing, synthetic biology, materials synthesis and characterization, and energy storage.
