Particle physicist Fabiola Gianotti has become the first woman to head CERN, the organization based in Switzerland that is home to the Large Hadron Collider. She succeeds outgoing director-general Rolf Heuer, who oversaw the laboratory’s operations for the last seven years.
Basic physics suggests that electrons are essentially immortal. A fascinating experiment recently failed to overthrow this fundamental assumption. But the effort has produced a revised minimum lifespan for electrons: 60,000 yottayears, which is — get this — about five-quintillion times the current age of the Universe.
The nuclear strong force binds the smallest bits of matter together to form atoms, thereby making our material world possible. Physicists at Brookhaven National Laboratory have made the first-ever measurement of a similar strong force for antimatter — the mirror image of regular matter that lies at the heart of one of…
There’s a long and colorful history of people trying to unlock the secret of how the Egyptian pyramids were built—and possibly find hidden rooms and corridors, for good measure. And now, a new international project aims to peer through the stone walls of these ancient structures, using cosmic rays.
“Space is big,” said Douglas Adams. “You just won’t believe how vastly, hugely, mind-boggingly big it is.” But why must this be so? And why does our Universe exhibit such tremendous scale, from the very tiny to the extremely large? Here are some possible answers.
After two years of upgrades, the world’s largest particle accelerator is back in business. And it’s already bashing subatomic particles together at higher energies than ever before to probe the most fundamental questions about the nature of the universe.
Late yesterday, CERN scientists made history by using the most powerful particle accelerator in the world to hurl beams of protons together at the record-breaking energy of 13 TeV (tera-electronvolts) — a full 5 TeV higher than the previous standard.
Particle physicist and musician Piotr Traczyk has taken data plots from the historic discovery of the Higgs boson and converted it into music that can be played by two guitars. Heavy metal guitars, to be more precise. The result is as nerdy as it is excellent.
The electronic camera on a chip in your smartphone is the same style of technology used in the Large Hadron Collider. Now a group of astrophysicists wants to capitalize on the similarity to recruit citizen sciences to track the fallout from ultra high energy cosmic rays hitting our atmosphere.
Katie Silver has penned an article for BBC Earth in which she explores the idea of finding a single theory that describes the entire Universe. But as her article aptly points out, it's a challenge that appears to be getting increasingly difficult.
It's been closed for renovations and upgrades since 2013, but on Sunday, the Large Hadron Collider powered on with no sign of complications, and successfully carried two proton beams, fired in opposite directions, around its 27km circumference.
Information can escape the clutches of a black hole, say researchers from Buffalo University. And incredibly, they say this information is not just gobbledygook — it can actually be deciphered to show what lies beneath.
The Large Hadron Collider (LHC) is the most audacious physics experiment in human history. Now scientists are about to restart the giant particle collider for a new set of experiments. Last time, they did the almost-impossible and found the Higgs Boson. This time, they might find something even more exciting.
The staff of symmetry has created a fun set of physics-themed Valentines to share with the people you love. And because ours is a universe that contains both matter and antimatter, they've created a complementary set of anti-Valentines, for the people you love to hate.
Since 1922, astronomers have been baffled as to the precise origin and composition of the diffuse interstellar bands seen through the Milky Way's stellar medium. This new interactive map doesn't solve the mystery, but it shows us exactly where these enigmatic molecules reside.
The coming year is shaping up to be a rather extraordinary one. Over the next 12 months, we'll be visiting dwarf planets, unlocking the secrets of a 400,000-year-old genome, and resuming the hunt for exotic particles. Here are the science stories to look out for in 2015.
A helium balloon fitted with six telescopes is currently floating over Antarctica. It's called SPIDER, and it could show what happened during the Big Bang. Scientists will use it to search for patterns of polarization that could have only been made in primordial light in the fractions of seconds after the birth of the…
We're made of flesh and bone and fat, which are in turn made of protons and electrons, which are (mostly) made of quarks. Which, even though they are the most basic form of matter, are a minuscule percentage of your body's mass. Wait, what? Why do we have so much more mass than what we're made of?
It appears that our planet's built-in force field is much stronger than we thought. Scientists studying the Van Allen belts have discovered the presence of a nearly impenetrable barrier that prevents some of the fastest and most powerful "ultrarelativistic" electrons from reaching the surface.
Particle physicists working at the Large Hadron Collider have detected two new subatomic particles that were predicted to exist but never seen. The discovery of the two new baryon particles stands to deepen our understanding of the universe.
