Citizen scientists discover hidden galaxies at record speed

The distant universe looks a little clearer, thanks to tens of thousands of citizen scientists who classified more than 6 million images over three days. This week, encouraged by a program on the BBC, more than 55,000 citizen scientists powered up th... Continue reading

Former CMS deputy takes reins of experiment

Tiziano Camporesi became head of the CMS experiment this month as UC Santa Barbara physicist Joe Incandela’s term came to a close. At the beginning of the month, physicist Joe Incandela, who led the CMS experiment during the discovery of the Hi... Continue reading

Astrophysicists use lens to study black-hole jet

Using an entire galaxy as a lens to look at an object in the far distance, researchers are learning more about powerful jets emitted when matter falls into a black hole. Using an astronomer’s trick, scientists analyzing data from the Fermi Gamma-ra... Continue reading

Particle accelerators join fight against brain cancer

Accelerator technology could be key to developing an effective treatment for a type of brain tumor currently considered incurable. One of the most common and aggressive types of malignant tumor originating in the human brain is called a glioblastoma ... Continue reading

Physicists harness the power of probability

What do the stock market, weather models and the discovery of the Higgs boson all have in common? They all are deeply indebted to statistics. Albert Einstein was greatly disturbed by the idea that the universe is governed by an intrinsic randomness. ... Continue reading

Physicists look toward the high-energy horizon

A panel met at Brookhaven National Laboratory to chart the course for US investment in particle physics experiments. Nature guards its secrets closely, and there may be more than one way to pry them free through experiments at the frontiers of partic... Continue reading

Santa at nearly the speed of light

This time of year, children who know their physics may start to question if Santa could possibly be real. As symmetry pauses for the holidays, we offer this thought experiment to put their hearts at ease. About this time of year, inquisitive chi... Continue reading

CERN’s Lego scavenger hunt

Somewhere inside the CERN Computing Centre lurk a werewolf, a gorilla, a leprechaun and other tiny exotic creatures. How many can you find? Stefan Lüders—CERN’s computer security officer—loves Legos. He started collecting them as a kid and lat... Continue reading
