More frequencies of light can pass between two coupled wavy waveguides than between two coupled straight ones, something that could allow for more flexible designs of optics-based circuits on silicon chips.

A trapped nanoparticle interacting with a laser provides a simple way to generate squeezed light, which has an unusually low level of fluctuations.
Project Mosquito barely got underway before it hit a dead end, with potential overseas designs waiting in the wings.

The man is among a handful who have gone into remission after the procedure, but it is not an option for most people.
Scientists have just found that using cubic boron arsenide in semiconductors could prove to be much better than silicon. Is silicon on its way out the door?
But Lindgren received an abrupt request to comment on the day’s big news: the new Russian space chief Yuri Borisov said the nation, which has been a steady NASA partner in space and that has ferried American astronauts up to the ISS as recently as 2020, would end their decades-long space station collaboration.
The news spread on Tuesday after the Kremlin published a transcript meant to represent a dialogue between Borisov and President Vladimir Putin, in which Borisov tells Putin that Russia will end their partnership on the ISS in 2024.
“That’s a good question,” Lindgren said after twiddling with the microphone in microgravity.
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.”
