#sensing technology

"Scientists first detected electrical “brain waves” a century ago, but seeing large-scale patterns of these neural oscillations has remained a challenge. Now, researchers have developed an optical technique for capturing these waves up to frequencies of roughly 100 Hz.

The technique, dubbed TEMPO (for “trans-membrane electrical measurements performed optically”), incorporates an optical-fiber sensor that can detect electrical activity in the brains of mice while they are awake and moving, rather than sedated (Cell, doi:10.1016/j.cell.2025.06.028). TEMPO also uses an optical “mesoscope,” an imaging device with a wide field of view and high spatial resolution. “This technology allows us to look at multiple brain areas at once and see the brain waves sweeping across the cortex with cell-type specificity,”(...)."

"The Stanford researchers say their illumination is roughly 10 times more stable than existing voltage-sensing photometry systems. This type of stability is key to picking up the signals from genetically encoded voltage indicators (GEVIs), or proteins that fluoresce in response to voltage differences across cell membranes."

“The latest images of Jupiter from the James Webb Space Telescope (JWST) are stunners.Captured on July 27, the infrared images—artificially colored to make specific features stand out—show fine filigree along the edges of the colored bands and around the Great Red Spot and also provide an unprecedented view of the auroras over the north and south poles.”

“"This image illustrates the sensitivity and dynamic range of JWST's NIRCam instrument," Fouchet said. "It reveals the bright waves, swirls and vortices in Jupiter's atmosphere and simultaneously captures the dark ring system, 1 million times fainter than the planet, as well as the moons Amalthea and Adrastea, which are roughly 200 and 20 kilometers across, respectively. This one image sums up the science of our Jupiter system program, which studies the dynamics and chemistry of Jupiter itself, its rings and its satellite system."”

“Archaeologists are aware of the voids thanks to a previous scan but they're planning to use more intense tech to get a better look.“

A team of researchers revealed in their study: "We plan to field a telescope system that has upwards of 100 times the sensitivity of the equipment that has recently been used at the Great Pyramid."

“Spectacular ice age landscapes beneath the North Sea have been discovered using 3D seismic reflection technology. Similar to MRI (magnetic resonance imaging) the images reveal in unprecedented detail huge seafloor channels—each one 10 times wider than the River Thames.

For the first time an international team of scientists can show previously undetectable landscapes that formed beneath the vast ice sheets that covered much of the UK and Western Europe thousands to millions of years ago. These ancient structures provide clues to how ice sheets react to a warming climate.

“Entanglement is the basis for quantum communication and quantum sensing. It can be understood as a quantum link between two objects which makes them behave as a single quantum object.”
