‘Naturally Insulating’ Material Emits Pulses of Superfluorescent Light at Room Temperature

Graphic shows process of achieving superflorescence at room temperature.
The process for achieving superflorescence at room temperature is shown in a new paper in Nature Photonics.

Researchers looking to synthesize a brighter and more stable nanoparticle for optical applications found that their creation instead exhibited a more surprising property: bursts of superfluorescence that occurred at both room temperature and regular intervals. The work could lead to the development of faster microchips, neurosensors, or materials for use in quantum computing applications, as well as a number of biological studies.

Superfluorescence occurs when atoms within a material synchronize and simultaneously emit a short but intense burst of light...

X-Shaped Radio Galaxies might Form More Simply than expected

X-shaped radio galaxies might form more simply than expected

Simple simulation accidentally leads to X-shaped galaxy for first time. When astronomers use radio telescopes to gaze into the night sky, they typically see elliptical-shaped galaxies, with twin jets blasting from either side of their central supermassive black hole. But every once in a while — less than 10% of the time — astronomers might spot something special and rare: An X-shaped radio galaxy, with four jets extending far into space.

Although these mysterious X-shaped radio galaxies have confounded astrophysicists for two decades, a new Northwestern University study sheds new insight into how they form — and its surprisingly simple. The study also found that X-shaped radio galaxies might be more common than previously thought.

The study will be published on Aug...

Revealing Roles of Dementia Proteins in Normal Memory

This study maps tau interactomes in mouse brain and neurons using proximity labelling. Direct interaction of tau with the vesicle and receptor trafficking factor NSF inhibits NSF ATPase activity and controls synaptic glutamate receptors underlying associative learning.

New research has revealed how the tau protein, a critical element in the formation of Alzheimer’s disease, is also involved in normal learning processes in the healthy brain — potentially providing a focal point for future drug therapies.

In the study, published in The EMBO Journal, Flinders University researchers have provided new insights into the tau protein, whose role has long been enigmatic, finding it may help molecular processes of memory formation.

Employing a sensitive method named proximity labelling, th...

A Silicon Image Sensor that Computes

As any driver knows, accidents can happen in the blink of an eye—so when it comes to the camera system in autonomous vehicles, processing time is critical. The time that it takes for the system to snap an image and deliver the data to the microprocessor for image processing could mean the difference between avoiding an obstacle or getting into a major accident.

In-sensor image processing, in which important features are extracted from raw data by the image sensor itself instead of the separate microprocess...
