Antimatter
-
In a move that would please the fictional Star Trek engineer Mr. Scott, CERN is working on ways to store and transport antimatter. This isn't to power any starships secretly under construction, but as a way to better study antiprotons.
-
Antimatter is a tricky substance to store and transport, mostly because it annihilates any container you try to put it in. Now CERN researchers have outlined a new antimatter trap designed to safely carry the volatile stuff to new facilities.
-
The Standard Model of particle physics still has some holes in it. Now, a new study outlines how one hypothetical particle, the axion, may be the answer to three separate, massive mysteries of the universe – including why we’re here at all.
-
Equal amounts of matter and antimatter should have been created in the Big Bang, but this would just have annihilated itself. Now, physicists have proposed a new theory that explains the mystery – and outlined how we can find direct evidence of it.
-
The hunt for dark matter – the mysterious stuff that seems to outnumber regular matter by a ratio of five to one – has so far turned up no direct trace. Now, researchers at CERN have tried a new approach, using another strange substance – antimatter.
-
Physics tells us that a hammer and a feather, dropped in a vacuum, will fall at the same rate. Now, CERN scientists are preparing to drop antimatter in a vacuum chamber to see if gravity affects it the same way it does matter – or if antimatter falls upwards instead.
-
Particle accelerators have plenty to teach us, but these facilities involve kilometers of tunnels and equipment. Now, researchers at Imperial College London have developed a new way to accelerate antimatter particles using common equipment already found in many labs, in a much smaller space.

NOAA flew a scientific aircraft right through Hurricane Patricia in 2015. Now, the researchers have reported their findings, including the detection of a beam of antimatter being blasted towards the ground, accompanied by flashes of x-rays and gamma rays.
-
A five-year experiment is underway in central Italy to determine whether the decay of heavy neutrinos shortly after the Big Bang can explain why the universe is composed mostly of matter and very little antimatter.
-
Antimatter is tricky to store and study, since it will vanish in a burst of energy if it touches regular matter. How can you transport something that will annihilate any physical container you place it in? Now, CERN researchers are planning to trap and truck antimatter from one facility to another.
-
Gamma ray bursts are mysterious signals blasting in from the deepest reaches of space, and we still don’t have much of an idea about what causes them. In order to help unlock the secrets, researchers have managed to recreate mini gamma ray bursts in the lab for the first time.
-
There’s much more to lightning than a flash and thunder. Lightning strikes have been known to generate gamma rays, and now a team of Japanese researchers has found that those bursts can create photonuclear reactions in the atmosphere, resulting in the production – and annihilation – of antimatter.
