New studies of the oldest light and sound in the cosmos suggest novel physics—rather than systematic errors—could explain an unsolved scientific mystery.
In 2023, the ALICE experiment was ready for their best year yet, until a mysterious signal threatened everything. As the LHC wraps up its 2025 lead-ion run, physicists recall how they worked together to solve the puzzle.
In the 1990s, astronomical observations revealed that the expansion of the universe is accelerating. Not knowing what causes this acceleration, scientists began to attribute the phenomenon to some unknown source of energy, coined "dark energy" by astrophysicist Michael Turner.
Ken McMullen says he does not feel comfortable with categories. That's why when, given a choice between defining himself as a painter or a film-maker, he prefers to be called an artist instead.
Chip Edstrom routinely tidies the Fermilab Main Control Room to stay awake while working as an accelerator operator on the owl shift. One night, while cleaning equipment and peeling off decades-old labels, Edstrom decided to replace the old ones with fresh ones. In Russian.
Berkeley Lab physicist Hitoshi Murayama and SLAC physicist Herman Winick have provided audio segments for One-Minute How-To, a Web site that provides 60-second explanations ranging from "How to write a flawless email," to "How to organize a river clean-up," to "How to sto
Even in the company of a two-story nose-picking machine, human cupcakes, battling robots, and power-tool drag races, the giant Tesla coil stands out. Maybe it's the loud buzz and crackle of artificial lightning bolts, writhing like fiery serpents from the top of the thing.
Scientists have sought to create better medical imaging techniques ever since Wilhelm Röntgens 1896 discovery that X-rays can reveal bones and other anatomical structures in a noninvasive way.
