1,050 °C from sunlight: better blast furnaces for steel production

Instead of replacing coal with hydrogen, the direct route promises to be much more efficient. You would only need enough mirrors to capture sufficient sunlight, which has hardly been practical up to now. A new material is now set to change this.

Strategy games a dying breed study claims — interest wanes in tactical gameplay mechanics despite steady player counts

A recent survey of 1.7 million gamers found that games that involve “strategic thinking and planning” are becoming less popular amongst gamers. Out of twelve different motivations, strategic thinking in games has seen the biggest decline, regardless of gender or nationality, and researchers speculate that declining attention spans may contribute to the lack of interest in strategy-centric games.
