Exploring collective interactions of matter and antimatter

STRIP AWAY ELECTRONS FROM THEIR ATOMS and you get a plasma — a collection of negatively charged electrons and positively charged ions. But at high energies around compact cosmic objects such as black holes, quasars Continue Reading →

The Princeton Plasma Physics Laboratory: The quest for clean energy continues

FUSION — the energy-making process that powers the sun — could provide us with a near limitless source of energy, ending our dependence on fossil fuels for making electricity. This summer, after a nearly three-year Continue Reading →

Elusive particles found

IN THE PAST YEAR, PRINCETON PHYSICISTS have detected two particles that were predicted decades ago to exist but had not been found until now. Both particles were detected using a scanning-tunneling microscope to image the Continue Reading →

Striking resemblance: A physical law may govern very different biological activities

FLOCKS OF BIRDS FLY ACROSS THE SKY in shifting configurations. In the retina of an eye, millions of neurons ignite in ever-changing combinations, translating light into meaningful images. Yet both of these seemingly random behaviors Continue Reading →

A farewell to arms? New technique could aid nuclear disarmament

SCIENTISTS at Princeton University and the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) are developing a system to verify the presence of nuclear warheads without collecting classified information, as a step toward the Continue Reading →

Telescopes take the universe’s temperature

Two telescopes on a Chilean mountaintop are poised to tell us much about the universe in its infancy. They are surveying the faint temperature fluctuations left over from the explosive birth of the universe, with Continue Reading →

Planck mission brings universe into sharp focus

Princeton researchers contributed extensively to the Planck space mission that earlier this year released the most accurate and detailed map ever made of the oldest light in the universe, revealing new information about its age, Continue Reading →
