Harnessing muons allows us to see through and inside objects to uncover their secrets.
A muon beam discovered a previously unknown room deep inside the Great Pyramid at Giza. Now DARPA wants to build muon beam imagers.
This is because cosmic rays consist of electrically charged particles, meaning as they journey billions of light-years from their source to Earth, they are repeatedly deflected by the magnetic fields of galaxies, making their sources impossible to spot.

Some of the processes and events that launch cosmic rays also blast out astrophysical neutrinos, and these ‘ghost-like’ particles could be used as ‘messengers’ to solve this puzzle, a team of astrophysicists believes.
City College of New York physicist Pouyan Ghaemi and his research team are claiming significant progress in using quantum computers to study and predict how the state of a large number of interacting quantum particles evolves over time. This was done by developing a quantum algorithm that they run on an IBM quantum computer. “To the best of our knowledge, such particular quantum algorithm which can simulate how interacting quantum particles evolve over time has not been implemented before,” said Ghaemi, associate professor in CCNY’s Division of Science.
Entitled “Probing geometric excitations of fractional quantum Hall states on quantum computers,” the study appears in the journal of Physical Review Letters.
“Quantum mechanics is known to be the underlying mechanism governing the properties of elementary particles such as electrons,” said Ghaemi. “But unfortunately there is no easy way to use equations of quantum mechanics when we want to study the properties of large number of electrons that are also exerting force on each other due to their electric charge.”

New research shows a direct interaction between dark matter particles and those that make up ordinary matter.
A new paper, published in the *Astronomy and Astrophysics* journal, discovered unexpected characteristics for the elusive dark matter that likely goes against our best theory of the universe — the Lambda-Cold Dark Matter model.

We’re only days into James Webb’s scientific operations, and the giant infrared observatory has already broken its own record for the most distant galaxy ever observed.
Last week, a team unearthed an observation of a galaxy that existed 400 million years after the Big Bang. This week, a new analysis revealed a galaxy a mere 235 million years after the Big Bang. It is located 35 billion light-years away from Earth.
James Webb peers further into the universe than ever before

New software being developed at MIT is proving able to autonomously repair software bugs by borrowing from other programs and across different programming languages, without requiring access to the source code. This could save developers thousands of hours of programming time and lead to much more stable software.
Bugs are the bane of the software developer’s life. The changes that must be made to fix them are often trivial, typically involving changing only a few lines of code, but the process of identifying exactly which lines need to be fixed can be a very time-consuming and often very frustrating process, particularly in larger projects.
