SLAC National Accelerator Laboratory —

Tangled magnetic fields power cosmic particle accelerators

SLAC scientists find a new way to explain how a black hole’s plasma jets boost particles to the highest energies observed in the universe. The results could also prove useful for fusion and accelerator research on Earth.

Watching brain cells fire in real time

Brain scientists have plenty of ways to track the activity of individual neurons in the brain, but they’re all invasive. Now, Daniel Palanker and colleagues have found a way to literally watch neurons fire – no electrodes or chemical modifications required.

How bacterial communities transport nutrients

Figuring out how bacteria bring in nutrients could point to ways of killing them without poison. This research could also reveal how small organisms cooperate by generating networks of flow patterns.

A glimpse into future oceans

Volcanic carbon dioxide vents off the coast of Italy are rapidly acidifying nearby waters. This natural laboratory provides a crystal ball-view into potential future marine biodiversity impacts around the world.

Receiving genetic information can change risk

Simply learning of a genetic risk can alter a person’s physiology, a recent study found, causing people to perform less well on exercise tests or altering hormones that indicate fullness after a meal.
