A novel meta-absorber efficiently captures noise across seven octaves–spanning most of the human hearing range–by engineering how fine-tuned resonator arrays manipulate and dissipate energy.
New research in FEBS Open Bio reveals the potential of compounds that inhibit bitter taste receptors to make artificial sweeteners more palatable.
Australian researchers have developed LAARMA — the world’s first AI-powered roadside system that detects wildlife near roads and warns drivers in real time, cutting vehicle speeds and reducing collision risk.
Tested in Far North Queensland cassowary hotspots, LAARMA detected birds with 97% accuracy and triggered flashing signs that slowed drivers by up to 6.3 km/h. The system uses self-learning AI that gets smarter over time — no reprogramming needed.
In a global first, the AI code is now open source on GitHub, meaning conservationists worldwide can adapt it to protect species from red pandas in Nepal to snow leopards in Central Asia.
Why it matters:
Protects endangered wildlife and human lives.
Low-cost, deployable at crash-prone locations.
Globally adaptable for different species.

A recent study published in the International Journal of Extreme Manufacturing by researchers from Beijing University of Technology and international collaborators investigates atomic-scale electrochemical deposition as a method for precise control of material properties. The research highlights the potential of this technique to support future developments in areas such as semiconductors, quantum computing, and nanomedicine.
A landmark study published in the Journal of Palaeogeography (Chinese Edition) uncovers how plume-driven tectonics shattered a Permian carbonate ramp into a complex platform system, creating a 400-kilometer-long dolostone hydrocarbon reservoir belt now pivotal to China’s energy exploration. Led by Prof. Yuan Haifeng (Chengdu University of Technology) and Dr. Zhang Benjian (PetroChina Southwest Oil and Gas Field Company), the research resolves decades of debate by precisely dating the tectonic-sedimentary pattern transition to 263–262 Ma using conodont biostratigraphy, while also revealing novel exploration targets.
