KAIST researchers have developed a compact, high-resolution spectrometer using double-layer disordered metasurfaces, enabling precise light wavelength analysis in devices smaller than a fingernail, with potential applications in daily life and various scientific fields.
LG Electronics has unveiled its plans for the 2024 "UltraGear" gaming monitor lineup, featuring two new OLED designs in 39" and 32" sizes. The 32GS95UE model will offer a high refresh rate and high-resolution mode, allowing users to switch between a blazing-fast 480Hz refresh rate for esports and high-refresh-rate gaming, and a 4K resolution mode with a 240Hz refresh rate for media consumption. It will also feature the industry's first "Pixel Sound Technology" for improved audio. LG has additional releases planned for CES 2024, including a 39-inch curved monitor and various other sizes.
An upcoming HONOR flagship phone, possibly from the Magic 6 series, is rumored to feature a 160MP periscope telephoto camera, surpassing the current highest-resolution telephoto cameras on rival handsets. While higher resolution allows for better long-range zoom, it may result in reduced image quality in low-light conditions. Leaks also suggest that the vivo X100 Pro Plus could potentially outdo HONOR with a 200MP telephoto camera. The HONOR phone is also expected to include 3D face unlock and other camera enhancements.
The recently launched HOTSAT-1, a high-resolution thermal satellite camera, is capturing never-before-seen thermal images of the Earth's surface temperature. With a resolution of 33 feet, it can detect temperature differences in the built and natural environment. The data collected by HOTSAT-1 will aid in monitoring wildfires, analyzing heat escape from roads and buildings, and improving energy-efficient infrastructure. The satellite operates by detecting heat, which is a longer wavelength than visible light, presenting a challenge in capturing clear images while traveling at high speeds in space.
Samsung appears to be developing two new ISOCELL camera sensors, the HW1 and HW2, with a resolution of 432 megapixels. While not exactly 1-inch sensors, they are close in size and will likely be marketed as such. The Galaxy Z Fold 6 is expected to use the same sensor as the Galaxy Z Flip 5, while the Galaxy Z Fold 7 may feature a 200-megapixel ISOCELL HP5 camera. It remains to be seen when these sensors will be released and which phones will utilize them.
Samsung is reportedly expanding its ISOCELL series of mobile device image sensors with new variants, including a 440MP sensor for automotive applications. However, the upcoming Samsung Galaxy S25 Ultra is expected to miss out on the latest 200MP ISOCELL sensor due to cost considerations. Instead, Samsung is rumored to be focusing on integrating the new sensors into devices like the next-gen Vivo X or Redmi Note series.
Scientists have developed a unique microscope called the ExA-SPIM, originally designed for defect detection in electronics manufacturing, that can capture high-resolution images of the brain. This microscope could provide unprecedented details and advance our understanding of the brain's structures and functions, benefiting neuroscience research and tissue analysis.
Researchers have developed a new brain imaging technique called Scattered Light Imaging (SLI) that combines light and X-ray scattering with MRI to map neural connections in the brain. SLI provides high-resolution results, particularly in regions with densely packed and interwoven nerve fibers, and is faster, cheaper, and more accessible than existing techniques like small-angle X-ray scattering (SAXS) and diffusion magnetic resonance imaging (dMRI). The technique could aid in understanding brain function and dysfunction and has potential applications in clinical research.
Scientists at the University of Tokyo have successfully arranged quantum sensors at a nanoscale to detect extremely small variations in magnetic fields. The high-resolution quantum sensors have potential uses in quantum materials and electronic device research, including developing hard disks that use nano-magnetic materials as storage elements. The researchers used boron vacancies or lattice defects in the two-dimensional hexagonal boron nitride to create nano-sized quantum sensors on the surface of the measurement target. The boron vacancy defect acts as an atom-sized quantum sensor for magnetic field measurements, behaving like a nano-sized “magnetic needle”.
Researchers at Duke's Center for In Vivo Microscopy have developed an MRI that can capture images of a mouse brain at a resolution 64 million times better than a clinical MRI for humans. The refined MRI provides an important new way to visualize the connectivity of the entire brain at record-breaking resolution, offering hope of understanding neurodegenerative diseases like Parkinson's and Alzheimer's. The researchers say new insights from mouse imaging will in turn lead to a better understanding of conditions in humans.
