Tech Xplore / Optical wireless quantum security: Free-space QKD and Li-Fi in one system
The German consortium QuINSiDa has achieved a major step toward mobile quantum-secure communication. They demonstrated a one-of-a-kind free-space data transfer channel supporting, for the first time, LiFi and major quantum ...
Phys.org / Gold-coated optical fiber rapidly gathers microscopic targets for faster, more sensitive detection
Osaka Metropolitan University researchers have developed a light-driven technique that quickly amasses thousands of bacteria into a single spot, boosting detection speed and sensitivity. Their approach paves the way for earlier ...
Phys.org / Neptune's mysterious moon Nereid may be original survivor of Triton's chaotic arrival
Neptune's far-flung moon Nereid may be the last of the planet's original companions that managed to survive a cosmic crash, scientists reported Wednesday.
Science X / A 6,000-year-old necropolis in central Spain is forcing a radical rethink of who built Europe's first great tombs
Archaeologists working in Toledo, central Spain, have discovered what they believe is the oldest documented monumental necropolis in the interior of the Iberian Peninsula. This ancient site dates back to about the end of ...
Medical Xpress / RSV mutations tied to severe childhood cases uncovered after 2022 surge
Respiratory Syncytial Virus (RSV) is a common childhood disease. Most people catch and recover from it by the age of three. 2022 was different, though. There was a severe and early outbreak of RSV that overwhelmed hospitals.
Medical Xpress / Short exposures to common air pollutants have distinct impacts on lung function and brain activity, study shows
New research by a collaboration of U.K.-based scientists has revealed that common indoor and outdoor air pollutants can alter both brain and respiratory function within just four hours of exposure, offering key insights into ...
Phys.org / Physicists figure out how to reduce formation of 'viscous fingers'
When they reach the bottom of a soap dispenser, frugal handwashers might try adding water to the bottle to push out the last bit of soap. But usually, the water drills right through the soap and jets out an only slightly ...
Phys.org / Researchers develop Bayesian inference for hidden dependence structures in multi-group high-dimensional data
In today's scientific and industrial fields, high-dimensional data in which numerous variables are observed simultaneously, such as genomic, climate, financial, and sensor data, are rapidly increasing. In such data, it is ...
Tech Xplore / AI's growing footprint raises fire safety challenges for data centers
Over the past decade, the ability of artificial intelligence to speed up complex processes has made it a key tool in engineering research. Many people associate AI with cloud computing, but its growth requires expanding infrastructure, ...
Phys.org / When order gives way to chaos—the turbulent birth of magnetic nanovortices
Magnetic switching processes are considered a prime example of controllable physics at the nanometer scale: in certain thin-film systems, a short electrical current pulse is sufficient to reverse the magnetization in a targeted ...
Phys.org / Researchers upcycle pomegranate peel into high-performance water purifier
Pomegranate peel discarded by food vendors could soon help clean up contaminated water, thanks to research from the Department of Chemistry at the Faculty of Science. Led by Professor Sam Li, the research team developed a ...
Phys.org / Nearly half of every T-shirt goes to waste before you even buy it
The global consumption of clothing is enormous. However, a significant portion of the textile fibers is lost before the garments even reach the market. "When we talk about textile waste, the debate often focuses on the clothes ...
