New particle discovered at CERN is a long-lived double charmer

Physicists at CERN have discovered an exotic new particle that’s quite charming. Known as Tcc+, the particle belongs to a rare class called tetraquarks, and its unusual composition makes it the longest-lived exotic hadron found so far.Continue ReadingC… Continue reading New particle discovered at CERN is a long-lived double charmer→

Laser pincers generate antimatter by recreating neutron star conditions

Some of the greatest mysteries in cosmology revolve around antimatter, and it’s hard to study because it’s rare and hard to produce in the lab. Now a team of physicists has outlined a relatively simple new way to create antimatter, by firing two lasers… Continue reading Laser pincers generate antimatter by recreating neutron star conditions→

The light galaxy at the heart of a dark dispute

Dark matter is considered the glue that holds galaxies together – but a few years ago, a team of astronomers claimed to have found a galaxy that didn’t have any. Other scientists later argued it was a calculation error, but now the original team has us… Continue reading The light galaxy at the heart of a dark dispute→

Particle seen switching between matter and antimatter at CERN

A subatomic particle has been found to switch between matter and antimatter, according to Oxford physicists analyzing data from the Large Hadron Collider. It turns out that an unfathomably tiny weight difference between two particles could have saved t… Continue reading Particle seen switching between matter and antimatter at CERN→

New state of matter unlocks a secret of perovskite solar cells

Perovskite solar cells are advancing at a rapid rate, and is drawing interest from scientists working to not just boost their performance but better understand how they offer such incredible, ever-increasing efficiencies. By turning their tools to pero… Continue reading New state of matter unlocks a secret of perovskite solar cells→

CERN scientists cool antimatter with lasers for the first time

Scientists at CERN have used lasers to cool down antimatter for the first time. The milestone could help unlock some of the secrets of this weird substance, including why it didn’t annihilate the universe soon after the Big Bang.Continue ReadingCategor… Continue reading CERN scientists cool antimatter with lasers for the first time→

CERN is building containers for storing and transporting antimatter

In a move that would please the fictional Star Trek engineer Mr. Scott, CERN is working on ways to store and transport antimatter. Sorry, this isn’t to power any starships secretly under construction, but as a way to better study antiprotons to learn m… Continue reading CERN is building containers for storing and transporting antimatter→

Cold gas cloud in our galaxy could be hiding universe’s missing matter

By studying the twinkling of stars, astronomers in Australia have discovered a huge cloud of cold gas in our galaxy, not far from Earth. This invisible mass could provide new hints about where to find the universe’s missing matter.Continue ReadingCateg… Continue reading Cold gas cloud in our galaxy could be hiding universe’s missing matter→

Mean temperature of the universe is rising over billions of years

Earth isn’t the only place that’s heating up of late – the universe seems to be too. Astronomers at Ohio State University have taken the mean temperature of cosmic gas at different distances and ages, and found that it’s roughly 10 times hotter today t… Continue reading Mean temperature of the universe is rising over billions of years→
