Winners declared in SUSY bet

Physicists exchanged cognac in Copenhagen at the conclusion of a bet about supersymmetry and the LHC. As a general rule, theorist Nima Arkani-Hamed does not get involved in physics bets. “Theoretical physicists like to take bets on all kinds of things,” he says. Show More Summary

Five facts about the Big Bang

It’s the cornerstone of cosmology, but what is it all about? Astronomers Edwin Hubble and Milton Humason in the early 20th century discovered that galaxies are moving away from the Milky Way. More to the point: Every galaxy is moving away from every other galaxy on average, which means the whole universe is expanding. Show More Summary

The $100 muon detector

A doctoral student and his adviser designed a tabletop particle detector they hope to make accessible to budding young engineering physicists. When Spencer Axani was an undergraduate physics student, his background in engineering led...Show More Summary

The physics photographer

Fermilab’s house photographer of almost 30 years, Reidar Hahn, shares four of his most iconic shots. Science can produce astounding images. Arcs of electricity. Microbial diseases, blown up in full color. The bones of a long-dead beasts. Show More Summary

#AskSymmetry Twitter chat with Risa Wechsler

See cosmologist Risa Wechsler's answers to readers' questions about dark matter and dark energy. [View the story "#AskSymmetry Twitter Chat with Risa Wechsler - Aug. 9, 2016" on Storify]

Dark matter hopes dwindle with X-ray signal

A previously detected, anomalously large X-ray signal is absent in new Hitomi satellite data, setting tighter limits for a dark matter interpretation.   In the final data sent by the Hitomi spacecraft, a surprisingly large X-ray signal previously seen emanating from the Perseus galaxy cluster did not appear.

Sterile neutrinos in trouble

The IceCube experiment reports ruling out to a high degree of certainty the existence of a theoretical low-mass sterile neutrino. This week scientists on the world’s largest neutrino experiment, IceCube, dealt a heavy blow to theories...Show More Summary

The contents of the universe

How do scientists know what percentages of the universe are made up of dark matter and dark energy? Cosmologist Risa Wechsler of the Kavli Institute for Particle Astrophysics and Cosmology explains. Video of d6S4PyJ01IA Have a burning...Show More Summary

LHC bump fades with more data

Possible signs of new particle seem to have washed out in an influx of new data. A curious anomaly seen by two Large Hadron Collider experiments is now looking like a statistical fluctuation. The anomaly—an unanticipated excess of photon...Show More Summary

Higgs boson resurfaces in LHC data

The Higgs appeared in the second run of the LHC about twice as fast as it did in the first. The Higgs boson is peeking out of the new data collected during the second run of the Large Hadron Collider, scientists reported today at the...Show More Summary

Q&A: The future of CERN

CERN’s Director General is enthusiastic about the progress and prospects of the LHC research program, but it’s not the only thing on her plate. Physicist Fabiola Gianotti started her mandate as the fifteenth Director General of CERN on January 1. Show More Summary

The deconstructed Standard Model equation

The Standard Model is far more than elementary particles arranged in a table. The Standard Model of particle physics is often visualized as a table, similar to the periodic table of elements, and used to describe particle properties, such as mass, charge and spin. Show More Summary

The Atomki anomaly

A result from an experiment in Hungary catches the attention of a group of theorists in the United States. Scientists at the Large Hadron Collider aren’t the only ones investigating a possible sign of a new particle. In a result published...Show More Summary

The most important website in particle physics

The first website to be hosted in the US has grown to be an invaluable hub for open science. With tens of thousands of particle physicists working in the world today, the biggest challenge a researcher can have is keeping track of what everyone else is doing. Show More Summary

Dark matter evades most sensitive detector

In its final run, the LUX experiment increased its sensitivity four-fold, but dark matter remains elusive.  After completing its final run, scientists on the Large Underground Xenon (LUX) experiment announced they have found no trace...Show More Summary

Pokémon Go shakes up the lab routine

At Fermilab and CERN, students, lab employees and visitors alike are on the hunt for virtual creatures. At Fermi National Accelerator Laboratory near Chicago, the normal motions of people going about their days have shifted. People who parked their cars in the same spot for years have moved.

The science of proton packs

Ghostbusters advisor James Maxwell explains the science of bustin'. There's a new proton pack in town. During the development of the new Ghostbusters film, released today, science advisor James Maxwell took on the question: "How would...Show More Summary

Who you gonna call? MIT physicists!

As science advisors, physicists Lindley Winslow and Janet Conrad gave the Ghostbusters crew a taste of life in the lab. Tonight, two MIT scientists are going to the movies. It’s not just because they want to see Kristin Wiig, who plays a particle physicist in the new Ghostbusters film, talk about grand unified theories on the big screen. Show More Summary

A primer on particle accelerators

What’s the difference between a synchrotron and a cyclotron, anyway? Research in high-energy physics takes many forms. But most experiments in the field rely on accelerators that create and speed up particles on demand. What followsShow More Summary

Scientists salvage insights from lost satellite

Before Hitomi died, it sent X-ray data that could explain why galaxy clusters form far fewer stars than expected. Working with information sent from the Japanese Hitomi satellite, an international team of researchers has obtained the first views of a supermassive black hole stirring hot gas at the heart of a galaxy cluster.
