New recyclable plastics found
PARIS — Scientists in the United States say they have devised a new class of plastics that can be recycled at room temperature and reshaped at standard manufacturing pressures, providing a potential breakthrough for one of the big environmental headaches.
Conventional plastics need to be heated to 200°C or more to be softened enough for remoulding. This treatment is expensive, carries environmental costs and weakens the material’s polymer chains, eventually making it unrecyclable.
Turkey, origin of Euro languages
PARIS —The vast group of languages that dominates Europe and much of Central and South Asia originated around 8,000 years ago among farmers in what is now Anatolia, Turkey.
So say a pair of New Zealand academics who have remarkably retraced the family tree of so-called Indo-European languages — a linguistic classification that covers scores of tongues ranging from Faroese to Hindi by way of English, French, German, Gujarati, Nepalese and Russian.
