Labs to hold particle physics photo competition

Participants will go behind the scenes at eight particle physics laboratories in Asia, Australia, Europe and North America. Back by popular demand, eight of the world’s leading particle physics laboratories are joining together to host...Show More Summary

Scientists below the surface

How do you get to work when your office is a clean room a mile below ground? Getting into the Majorana Demonstrator clean room is an adventure. Unless you have to do it every day for work, in which case, it’s probably a chore. It all starts in Lead, South Dakota, a town once built around and seemingly forever linked to the underground.

Combined results find Higgs still standard

The CMS and ATLAS experiments combined forces to more precisely measure properties of the Higgs boson. The ATLAS and CMS experiments on the Large Hadron Collider were designed to be partners in discovery. In 2012, both experiments reported...Show More Summary

Construction approved for world's most powerful digital camera

It would take 1500 high-definition television screens to display just one image from the Large Synoptic Survey Telescope's high-resolution camera. The US Department of Energy has approved the start of construction for a 3.2-gigapixel digital camera—the world’s largest—at the heart of the Large Synoptic Survey Telescope. Show More Summary

Looking for strings inside inflation

Theorists from the Institute for Advanced Study have proposed a way forward in the quest to test string theory. Two theorists recently proposed a way to find evidence for an idea famous for being untestable: string theory. It involves...Show More Summary

Scientists accelerate antimatter

Accelerating positrons with plasma is a step toward smaller, cheaper particle colliders. A study led by researchers from SLAC National Accelerator Laboratory and the University of California, Los Angeles, has demonstrated a new, efficient way to accelerate positrons, the antimatter opposites of electrons.

All about supernovae

Exploding stars have an immense capacity to destroy—and create. Somewhere in the cosmos, a star is reaching the end of its life. Maybe it’s a massive star, collapsing under its own gravity. Or maybe it’s a dense cinder of a star, greedily...Show More Summary

Q&A: Marcelle Soares-Santos

Scientist Marcelle Soares-Santos talks about Brazil, neutron stars and a love of discovery. Marcelle Soares-Santos has been exploring the cosmos since she was an undergraduate at the Federal University of Espirito Santo in southeast Brazil. Show More Summary

The age of the universe

How can we figure out when the universe began? Looking out from our planet at the vast array of stars, humans have always asked questions central to our origin: How did all of this come to be? Has it always existed? If not, how and when...Show More Summary

Dark Energy Survey finds more celestial neighbors

The observation of new dwarf galaxy candidates could mean our sky is more crowded than we thought. Scientists on the Dark Energy Survey, using one of the world’s most powerful digital cameras, have discovered eight more faint celestial objects hovering near our Milky Way galaxy. Show More Summary

MicroBooNE sees first cosmic muons

The experiment will begin collecting data from a neutrino beam in October. A school bus-sized detector packed with 170 tons of liquid argon has seen its first particle footprints. On August 6, MicroBooNE, a liquid-argon time projection...Show More Summary

Q&A: Underground machinist

What’s it like being the machinist at the deepest machine shop in the world? The Majorana Demonstrator searches for a rare decay process a mile below the surface at Sanford Lab in Lead, South Dakota. To craft the experiment’s precise...Show More Summary

Testing the nature of neutrinos

The Majorana Demonstrator experiment is looking for a sign that neutrinos are their own antiparticles. A mile below the Earth’s surface, a large copper cylinder sits behind a thick shield of lead bricks stacked into what could be confused for a wood-burning pizza oven. Show More Summary

NOvA experiment announces first results

The NOvA detector has seen its first neutrino oscillations. Scientists on the NOvA experiment saw their first evidence of oscillating neutrinos, confirming that the extraordinary detector built for the project not only functions as planned,...Show More Summary

The mystery of particle generations

Why are there three almost identical copies of each particle of matter? The Standard Model of particles and interactions is remarkably successful for a theory everyone knows is missing big pieces. It accounts for the everyday stuff we know like protons, neutrons, electrons and photons, and even exotic stuff like Higgs bosons and top quarks. Show More Summary

IceCube sees highest-energy neutrino ever found

Observations of this kind could lead scientists to the source of ultra-high-energy cosmic rays. In 2013, the IceCube neutrino experiment at the South Pole reported the observation of two ultra-high-energy neutrino events, which they named after Sesame Street characters Bert and Ernie. Show More Summary

One Higgs is the loneliest number

Physicists discovered one type of Higgs boson in 2012. Now they’re looking for more. When physicists discovered the Higgs boson in 2012, they declared the Standard Model of particle physics complete; they had finally found the missing...Show More Summary

Is this the only universe?

Our universe could be just one small piece of a bubbling multiverse. Human history has been a journey toward insignificance. As we’ve gained more knowledge, we’ve had our planet downgraded from the center of the universe to a chunk of...Show More Summary

W bosons remain left-handed

A new result from the LHCb collaboration weakens previous hints at the existence of a new type of W boson. A measurement released today by the LHCb collaboration dumped some cold water on previous results that suggested an expanded cast...Show More Summary

The Standard Model of particle physics

Explore the elementary particles that make up our universe. The Standard Model is a kind of periodic table of the elements for particle physics. But instead of listing the chemical elements, it lists the fundamental particles that make...Show More Summary
