- KAIST, the National University of Singapore (NUS), and Singapore Management University (SMU) jointly develop “SweepLED,” an AI technology that detects hidden cameras using only a smartphone and a LED device.
- SweepLED detects hidden cameras in chargers, clocks, remote controls, and other everyday objects in under five seconds, achieving approximately 94% detection accuracy.
- Introduces a low-cost, smartphone-based detection technology that accessible to everyday users without specialized equipment.
A new Concordia study finds that fast fashion’s carbon footprint can be significantly reduced by using sea rather than air freight, producing fewer garments and extending clothing lifespans, with durability potentially mattering more than whether a T-shirt is cotton or polyester. (concordia.ca)
UT researchers teamed up with the world's largest semiconductor foundry to fabricate and test an emerging memory technology that could help deal with the increasing energy demand of artificial intelligence.
Researchers have developed fluorescent molecules that permit imaging how DNA is packaged inside living cells at unprecedented resolution, and in preserved cells, close to the width of the double helix itself. The advance raises the possibility that one day they could train an AI to look at how DNA occupies three-dimensional space inside cells for diagnosing and treating cancer and other types of conditions.
Scientists from Gladstone Institutes, UC San Francisco, and Stanford University, in collaboration with Biohub, have unveiled a massive, high-resolution functional map of human immune cells that promises to transform our understanding of how genetics control health and disease. Published in the journal Cell, the study represents a landmark achievement in immunology and genomics. By systematically stress-testing genes across the genome in 22 million human immune cells, scientists moved beyond mere DNA sequencing to decode the dynamic circuits that govern how these genes actually work in the context of health and disease.
JMIR Publications this week released seven feature News and Perspectives articles covering how digital tools are transforming clinical research, public health readiness, health care institutions, and consumer choices.
Electrochemical CO2 reduction to formate is a promising route to convert greenhouse gases into value-added liquid chemicals, but persistent cell voltage rise during operation has long limited high-concentration product accumulation and long-term stability. A research team led by scientists from the University of Science and Technology Beijing has identified that unidirectional cation migration across the ion exchange membrane is the dominant cause of voltage growth, and proposed a simple yet effective "concentration-gradient" strategy. By pairing high-concentration anolyte (3.37 mol·L−1) with low-concentration catholyte (0.5 mol·L−1) to generate reverse diffusion potential, the strategy confines cell voltage fluctuations within ±0.5 V and enables over 30 hours of continuous stable operation — 3 to 4 times longer than conventional systems. Normalized formate productivity reaches 200% of the average level, and the strategy works universally across cation-based electrolyte systems.
Phosphine (PH3) is a deadly industrial byproduct that poses a severe threat to human health and the environment. A research team from Yunnan Minzu University and Kunming University of Science and Technology has developed a sustainable "waste-to-wealth" strategy that captures toxic PH3 tail gas and transforms it in situ into a robust Ni2P/Ni5P4 heterostructure electrocatalyst. This innovative approach not only achieves high-efficiency gas purification but also provides a low-cost, high-performance solution for green hydrogen production, bridging the gap between pollution control and clean energy.
