We need new fuels to transport people and goods around the globe as society moves away from coal, natural gas and oil. Here’s how things are shaping up.
Is nuclear power a necessary part of the energy transition away from fossil fuels? As the debate rages on, new technologies and smaller reactors may be shifting the balance.
An international treaty aims to bring the shipping industry to net-zero emissions by around 2050. Can novel fuels, wind power and coordination on a global scale get it there?
As wind power grows around the world, so does the threat the turbines pose to wildlife. From simple fixes to high-tech solutions, new approaches can help.
Scientists have been chasing the dream of harnessing the reactions that power the Sun since the dawn of the atomic era. Interest, and investment, in the carbon-free energy source is heating up.
The technology could transform how growers protect their harvests, by detecting plant diseases very early on. But the challenge is to develop tools that are as affordable as they are effective.
Innovative thinking has done away with problems that long dogged the electric devices — and both scientists and environmentalists are excited about the possibilities
For thousands of years, humanity has had a love affair with cement and concrete. But now, industry groups and researchers are seeking solutions to the huge amounts of carbon dioxide that cement-making generates.
In Nevada and other US states, entrepreneurs are anticipating the coming boom in retired lithium-ion batteries from electric cars and hoping to create a market for recycled minerals
Marketed to meat lovers, plant-based burgers like Impossible and Beyond claim to taste like the real thing and to have far lighter environmental footprints. Here’s what the numbers have to say.
Specialized glass that keeps heat in during winter and lets it out during summer could make buildings much more efficient — if costs and complexities don’t get in the way
The world’s natural history collections hold billions of biological specimens, many of which still contain DNA. Scientists exploring these genetic repositories are gaining new, historical perspectives on how animals evolve.
ACs and refrigerators help keep people safe — but they also further warm the planet. Scientists are working on eco-friendlier solutions as global demand for cooling grows.
Substances that persistently luminesce are already used in some bike lanes, and in the future could be applied to sidewalks, streets and buildings — saving energy and reducing urban heat
Covid-19 has been a stress test for the world’s food supply chains — and a preview of looming threats. That’s making efforts to improve the journey from farm to fork more urgent than ever.
