44+ min ago   (55+ words) Radar systems are the invisible guardians of modern aviation, shipping, and defense, but they operate in an increasingly hostile electromagnetic environment. Adversaries deliberately flood the spectrum with jamming signals designed to blind radars, confuse their receivers, and mask real targets....

1+ hour, 12+ min ago   (91+ words) Digital images have become the default currency of communication, evidence, commerce, and journalism, yet every photograph that travels across an open network is exposed to silent modification. A cropped receipt, a spliced face, a doctored medical scan, or an altered…...

1+ hour, 35+ min ago   (56+ words) Piezoelectric polymers have long promised a future in which the flex of a shoe sole, the flutter of a breath, or the vibration of a bridge quietly generates its own electricity, powering sensors and wearables without a single battery swap....

2+ hour, 37+ min ago   (489+ words) Tin halide perovskites have long been the tantalizing alternative to lead-based perovskites in next-generation solar cells. They offer a narrower bandgap that is ideal for harvesting more of the solar spectrum, and they replace toxic lead with an environmentally friendlier…...

2+ hour, 51+ min ago   (639+ words) Researchers at the University of Málaga have unveiled GenPot, a generative honeypot architecture that uses fine-tuned large language models to lure attackers into elaborate, entirely fake web services — and in a controlled trial, cybersecurity experts were unable to distinguish it…...

3+ hour, 35+ min ago   (84+ words) A sweeping new survey published in Multimedia Tools and Applications maps the full arc of the deepfake era, from the first crude face swaps to today’s diffusion models capable of producing hyper-realistic, temporally coherent synthetic video. The study, led by…...

4+ hour, 8+ min ago   (614+ words) A team of geotechnical engineers has released an open-source software package that could upend how slopes, dams, and embankments are analyzed around the world....

5+ hour, 11+ min ago   (698+ words) Perovskite solar cells have spent more than a decade rewriting the record books, but the most valuable real estate in these devices has always been the interface, the razor-thin boundary where the light-absorbing perovskite layer meets the contacts that siphon…...

5+ hour, 57+ min ago   (55+ words) Three-dimensional printing has rapidly become one of the most versatile fabrication strategies for advanced energy storage devices, offering unprecedented control over geometry, porosity and material distribution. Compared with conventional slurry-based manufacturing, which relies on coating, calendaring and layer-by-layer stacking, additive…...
