New epoch of miniaturized Cherenkov detectors
Recently, the research team led by Prof. Yu Luo from the school of Electrical and Electronic Engineering, Nanyang Technological University, discovered surface Dyakonov-Cherenkov radiation. This new type of Cherenkov radiation not only presages the ne.....»»
Designing detectors for DUNE
The most abundant, massive particles in the universe may be ones you've never even heard of: neutrinos. These particles are all around us—even streaming through us—though they almost never interact with other particles. They are so light and weak.....»»
3D-printed facet-attached microlenses (FaML) could overcome photonic packaging challenges
Photonic integrated circuits (PICs) are on the verge of significant disruption through the unlocking of novel applications. This success largely relies on advanced wafer-level miniaturized photonic device fabrication, combining outstanding functional.....»»
Crawford Lake: What the past can teach us about urban living today
When I heard that Crawford Lake in southern Ontario was selected as the "Golden Spike" candidate for placing the beginning of the Anthropocene epoch in 1950—essentially, the best place in the world to show how humans impacted the planet's fossil re.....»»
Did the Anthropocene start in 1950—or much earlier? Here"s why debate over our world-changing impact matters
It made world news last week when a small lake in Canada was chosen as the "Golden Spike"—the location where the emergence of the Anthropocene is most clear. The Anthropocene is the proposed new geological epoch defined by humanity's impact on the.....»»
New method to search for strongly interacting dark matter inside neutrino detectors
Physicists worldwide are trying to detect dark matter (DM) particles and their interactions with visible matter using various strategies and detectors. As these particles do not emit, reflect or absorb light, they have so far proved to be very diffic.....»»
A Novel Type of Neural Network Comes to the Aid of Big Physics
The machine learning tool is helping physicists with the daunting challenge of analyzing large but nearly empty data sets, like those from neutrino detectors or particle colliders......»»
Crawford Lake chosen as the primary marker to identify the start of the Anthropocene epoch
An international team of researchers has chosen the location which best represents the beginnings of what could be a new geological epoch, the Anthropocene......»»
Rapid fabrication of a polymer lens on a laser chip for miniaturized spectroscopy
There is a growing demand for portable gas sensors, from both environmental and health sciences users as well as industry. Resonant optical sensors, in particular planar micro-resonators, combine high sensitivity and small footprint, which makes them.....»»
Why AI detectors think the US Constitution was written by AI
Can AI writing detectors be trusted? We dig into the theory behind them. Enlarge / An AI-generated image of James Madison writing the US Constitution using AI. (credit: Midjourney / Benj Edwards) If you feed America's mo.....»»
Humans" impact on Earth began a new epoch in the 1950s called the Anthropocene, scientists say
From climate change to species loss and pollution, humans have etched their impact on Earth with such strength and permanence since the middle of the 20th century that a special team of scientists says a new geologic epoch began then......»»
Signs of the human era, from nuclear fallout to microplastics
As scientists make the case that humans have fundamentally transformed the planet enough to warrant our own geological epoch, another question arises: is there anything left untouched by humanity's presence?.....»»
Review: Unihertz Jelly Star: Miniaturized Maker Mobile
Manufacturer: Unihertz Kickstarter Campaign Price: $170 Unihertz Jelly Star: Miniaturized Maker Mobile? I remember my first phone: it was transparent blue, and it … plugged into the wall. But once things became a bit more mobile, I was very excite.....»»
Astronomers use dead stars to measure gravitational waves produced by ancient black holes
An international team of astronomers has detected a faint signal of gravitational waves reverberating through the universe. By using dead stars as a giant network of gravitational wave detectors, the collaboration—called NANOGrav—was able to meas.....»»
Next generation gravitational wave detectors could pin down dark matter
Gravitational astronomy is a relatively new discipline that has opened many doors for astronomers to understand how the huge and violent end of the scale works. It has been used to map out merging black holes and other extreme events throughout the u.....»»
NASA"s new detectors could improve views of gamma-ray events
Using technology similar to that found in smartphone cameras, NASA scientists are developing upgraded sensors to reveal more details about black hole outbursts and exploding stars—all while being less power hungry and easier to mass produce than de.....»»
Precision nuclear physics in Indium-115 beta decay spectrum using cryogenic detectors
Certain isotopes such as Indium-115 (In-115) are extremely long lived, taking over 100 trillion years for half of the Indium atoms to decay away. These isotopes allow scientists to probe the precise internal processes that govern other extremely long.....»»
