### Sticking with Scotland: Orkney’s Rare Mammals Recover as Stoats Are Eradicated
A conservation project on Scotland’s Orkney Islands aims to rid the archipelago of invasive stoats, which have upset the native ecosystem by preying on voles. Since the initiative started in 2019, the number of Orkney voles—the island’s unique mammal species—has reached its highest level in years. This recovery also benefits birds of prey like hen harriers and short-eared owls, which feed on voles. Ecologist Matt Marsh from the Orkney Native Wildlife Project expressed optimism about the positive trend.

### Weight Loss Drug to Target Heart Disease in the UK
The UK’s health service plans to prescribe semaglutide, the active compound in weight loss drugs Wegovy and Ozempic, to over one million people with cardiovascular disease. Clinical trials have shown semaglutide reduces the risk of heart attacks and strokes regardless of weight loss. It will be administered as a weekly injection along with lifestyle changes like a healthy diet and more exercise. Dr Sonya Babu-Narayan of the British Heart Foundation emphasized that semaglutide provides important health benefits beyond weight loss.

### Solar Breakthrough Could Boost Panel Efficiency by 30%
Researchers at Kyushu University, Japan, have reported a breakthrough in solar panel efficiency. Their prototype panels can capture solar energy with 130% efficiency by harvesting energy previously lost as heat, surpassing the conventional 100% efficiency limit. This “glass ceiling” breakthrough could lead to ultra-efficient solar panels in the future. The work is currently in the proof-of-concept stage, with further experiments planned.
