Nanoprinted high-neuron-density optical linear perceptrons perform near-infrared inference on a CMOS chip
Today, machine learning permeates everyday life, with millions of users every day unlocking their phones through facial recognition or passing through AI-enabled automated security checks at airports and train stations. These tasks are possible thank.....»»
A thousand times smaller than a grain of sand—glass sensors 3D-printed on optical fiber
In a first for communications, researchers in Sweden 3D printed silica glass micro-optics on the tips of optic fibers—surfaces as small as the cross section of a human hair. The advance could enable faster internet and improved connectivity, as wel.....»»
Nvidia could turn gaming handhelds on their head
Nvidia is rumored to be co-developing a chip with MediaTek that could power PCs and even handheld gaming devices......»»
Astronomers discover merging twin quasars
Using the Subaru Telescope in Hawaii, astronomers have detected a pair of merging quasars at a high redshift, as part of the Hyper SuprimeCam (HSC) Subaru Strategic Program (SPP) survey. The serendipitous discovery is reported in the latest issue of.....»»
Cybersecurity analysis exposes high-risk assets in power and healthcare sectors
Traditional approaches to vulnerability management result in a narrow focus of the enterprise attack surface area that overlooks a considerable amount of risk, according to Claroty. Organizations must take a holistic approach to exposure management T.....»»
Tiger beetles fight off bat attacks with ultrasonic mimicry
Bats, as the main predator of night-flying insects, create a selective pressure that has led many of their prey to evolve an early warning system of sorts: ears uniquely tuned to high-frequency bat echolocation. To date, scientists have found at leas.....»»
Here’s our best look yet at the iPad Pro’s new nano-texture display [Video]
As we rounded up last night, the first M4 iPad Pro reviews are here, with most focusing on the new OLED screens, the M4 chip, and the ultra-thin design. If you’ve been on the hunt for an in-depth look at the new nano-texture glass option, a new vid.....»»
Input from young and aspiring technicians wanted for survey
TechForce Foundation is soliciting feedback from new technicians and high school and post-secondary students enrolled in automotive training programs for its inaugural Techs Talk survey......»»
How to ensure biodiversity data are FAIR, linked, open and future-proof
Within the Biodiversity Community Integrated Knowledge Library (BiCIKL) project, 14 European institutions from ten countries, spent the last three years elaborating on services and high-tech digital tools, in order to improve the findability, accessi.....»»
Researchers elucidate ultrafast laser-induced solid-to-overdense-plasma transitions
The interaction of solids with high-intensity ultra-short laser pulses has enabled major technological breakthroughs over the past half-century. On the one hand, laser ablation of solids offers micromachining and miniaturization of elements in medica.....»»
"Dancing" raisins: A simple kitchen experiment reveals how objects can extract energy from their environment
Scientific discovery doesn't always require a high-tech laboratory or a hefty budget. Many people have a first-rate lab right in their own homes—their kitchen......»»
New optical tweezers can trap large and irregularly shaped particles
Researchers have developed new optical tweezers that can stably trap particles that are large—about 0.1 mm—and irregularly shaped. While conventional optical tweezers use highly focused laser beams to trap micro- or nano-scale rod shaped or spher.....»»
Beethoven likely didn’t die from lead poisoning, new hair analysis reveals
There was also mercury and arsenic but none of the toxins likely caused composer's death. Enlarge / Portrait of Beethoven by Joseph Karl Stieler, 1820. Toxocology analysis of the composer's locks of hair showed high levels of lea.....»»
Raw-milk fans plan to drink up as experts warn of high levels of H5N1 virus

Scientists create an "optical conveyor belt" for quasiparticles
Using interference between two lasers, a research group led by scientists from RIKEN and NTT Research have created an "optical conveyor belt" that can move polaritons—a type of light-matter hybrid particle—in semiconductor-based microcavities. Th.....»»
Apple explains why it hasn’t released a touchscreen Mac (yet?)
The first iPad Pro reviews are here, and as we rounded up earlier today, they focus a lot on the new OLED displays, the M4 chip, and the limitations of iPadOS as a platform. In an interview with The Wall Street Journal, Apple marketing executive Tom.....»»

Brazil's flooded south remained paralyzed Monday, with schools and health centers shut and streets cut off as overflowing rivers showed no sign of receding after torrential rains in a disaster that has left 147 dead......»»
Self-assembled Na-doped zinc oxide for the detection of lung cancer biomarker VOCs at low concentrations
Developing high-performance gas sensors for the detection of lung cancer markers at low concentrations is a crucial step towards achieving early lung cancer monitoring through breath tests. Metal oxide semiconductors (MOS) have long been sensitive to.....»»
Evolutionary history shapes variation of wood density: Study
Ecology and evolutionary biology suggest that closely related species are more likely to exhibit morphological and functional similarities compared to distantly related species. Each tree species represents a unique genetic reservoir and is a product.....»»
