Meal planning, shopping lists, soup from shrivelled vegetables - all valid ways of lowering food waste. Scientists, meanwhile, are constantly thinking of ways to reduce methane generated by food waste dumped at landfill sites. Using vegetables for solar cells, for example, or bread for drinks. Now researchers have discovered that leftover food can be converted to sustainable aviation fuel...

Black Lives Matter is changing things. Not least when it comes to financing startups. More and more venture capital firms are recognising the value of diverse teams and are investing accordingly. Now a non-profit diversity organisation from England has developed a certification programme. With it, VC companies can highlight their commitment to diversity and inclusion. With the help of...

Innovation is when two or more things combine to make something new. Or get rid of something. Like the startup making wind turbines minus the rotor blades (the latter are neither sustainable nor safe for birds.) The cylindrical turbines vibrate in the wind, generating electricity as they go. Gears, brakes or oil? Not required. A 2.75 metre high turbine...

Diarrhoea is easily recognised. Diabetes less so. Now an international team has developed an AI platform that could help detect vascular diseases. The system learns using a combination of 2D video images of blood flow and the laws of physics. This way, conclusions can be drawn about the speed of blood flow compared to healthy vessels, and how much...

We’re glad of our heating in winter. Greenhouse vegetables are too. But rooftop solar panels made from silicon cells can’t be used here to generate electricity sustainably. Because they take the light away from the plants. That’s why US researchers have been investigating the use of organic solar cells (OSCs). These require only a limited colour spectrum to generate...

Spending time in restaurants or pubs has become almost a thing of the past. And the beer industry is suffering too. Fear not, however, for a leading Manchester brewery has found a novel way of making sure its product is not wasted. Beer that was once destined for pubs is instead filled back into the brewing kettle and added...
