Keeping the photon in the dark
2025-07-09
Excitons – bound pairs of electrons and electron hole – are quasiparticles that can arise in solids. While so-called “bright” excitons emit light and are therefore accessible, dark excitons are optically inactive. As a result, they have a significantly longer lifetime – which makes them ideal for storing and controlling quantum states and using them for advanced methods to generate entanglement.
Gregor Weihs and his team from the Department of Experimental Physics at the University of Innsbruck, together with researchers in Dortmund, ...

Medical needles in the hands of AI
2025-07-09
Imagine a physician attempting to reach a cancerous nodule deep within a patient's lung – a target the size of a pea, hidden behind a maze of critical blood vessels and airways that shift with every breath. Straying one millimeter off course could puncture a major artery, and falling short could mean missing the cancer entirely, allowing it to spread untreated.
This is the high-stakes reality physicians face in thousands of procedures daily, where accuracy is critical and the task is complicated by anatomical obstacles that are non-penetrable or sensitive. Can artificial intelligence (AI) and robots help address these challenges and ...

Koalas spend only 1% of their life on the ground – but it’s killing them
2025-07-09
Koalas are a nationally endangered and iconic species in Australia, yet their populations are rapidly declining due to habitat loss, fragmentation, and disease, and very little is known about the fine-scale movements of koalas – especially when they’re on the ground. New research reveals that koalas only spend around 10 minutes per day on the ground, but this ground-time is associated with two-thirds of recorded koala deaths.
“Koalas are mostly tree-dwelling, but due to extensive land clearing, they’re increasingly forced to travel on the ground, which puts them at serious risk of injury and death,” ...
