Faster than one pixel at a time—new imaging method for neutral atomic beam microscopes

Posted by in category: futurism

Microscope images could be obtained much more quickly—rather than one pixel at a time—thanks to a new imaging method for neutral atomic beam microscopes developed by Swansea University researchers. It could ultimately lead to engineers and scientists getting faster results when they are scanning samples.

Crashes, blackouts and climate tipping points: How can we tell when a system is close to the edge?

Posted by in category: climatology

According to the infamous myth, groups of lemmings sometimes run off cliffs to their collective doom. Imagine you are one of these rodents: On a sunny day you join your companions in a joyous climb up a mountain beneath clear skies, traipsing across grass and dirt and rock, glad to be among friends, until suddenly you plunge through the brisk air and all goes black.

Physicists uncover new phenomena in fractional quantum Hall effects

Posted by in categories: particle physics, quantum physics

Imagine a two-dimensional flatland, instead of our three-dimensional world, where the rules of physics are turned on their head and particles like electrons defy expectations to reveal new secrets. That’s exactly what a team of researchers, including Georgia State University Professor of Physics Ramesh G. Mani and recent Ph.D. graduate U. Kushan Wijewardena, has been studying at Georgia State’s laboratories.

Theoretical research holds promise for advancing modular quantum information processing

Posted by in categories: quantum physics, supercomputing

The operation of a quantum computer relies on encoding and processing information in the form of quantum bits—defined by two states of quantum systems such as electrons and photons. Unlike binary bits used in classical computers, quantum bits can exist in a combination of zero and one simultaneously—in principle allowing them to perform certain calculations exponentially faster than today’s largest supercomputers.

Enhanced two-photon microscopy method could reveal insights into neural dynamics and neurological diseases

Posted by in categories: biotech/medical, neuroscience

Researchers have developed a new two-photon fluorescence microscope that captures high-speed images of neural activity at cellular resolution. By imaging much faster and with less harm to brain tissue than traditional two-photon microscopy, the new approach could provide a clearer view of how neurons communicate in real time, leading to new insights into brain function and neurological diseases.

Scientists characterize shale cap rocks at tiny scales

Posted by in category: nanotechnology

A team of researchers is working on a multidisciplinary approach to advancing the exploration of shale rock as a suitable geological seal for resource recovery and underground storage. Given that the pore space in shale rock is predominantly sub-micron, these studies focus on the micro and the nanoscale.

NASA’s DART: Crashing Into Discovery With World’s First Planetary Defense Test

Posted by in categories: futurism, space

Following NASA ’s DART mission, which successfully tested asteroid deflection techniques by colliding with the moonlet Dimorphos, extensive research has revealed insights into the geological features and evolutionary history of the Didymos asteroid system.

Studies have characterized the surface and interior of these celestial bodies, examined their formation processes, and assessed their response to impacts. These findings not only provide a clearer understanding of binary asteroid systems but also enhance planetary defense strategies.
