US president Joe Biden announced a pardon for thousands of people convicted for possession of marijuana under federal law

If the electricity supply from the continent ceases, households in England, Scotland and Wales may need to ration their own power use at peak times to keep the lights on

Falling launch costs for satellites mean space advertising may now make commercial sense, according to a feasibility study, but the idea remains controversial

Standard silkworm silk has been made stronger than spider’s silk, one of the toughest materials known, by bathing it with metals and respinning it

Astronomers used radio telescopes to estimate the temperature of molten rock on Io, the most volcanically active world in the solar system

Scientists have found three strange asteroids that orbit relatively close to the sun – one is the closest to the sun we’ve ever found, and another may someday hit Earth

Orchids that grow on trees in the forest canopy may access food by connecting to a network of fungal threads

Scientists have found a way to use leaked electromagnetic radiation to measure nutrients in microwaved meals

My late wife was an environmentalist and wanted an eco-friendly funeral. I have seen to her wishes, but a woodland burial isn't possible for all those who would like one, writes Graham Lawton

The UK government’s bid to slash environmental protections is an onslaught on nature and the laws that protect it. We are angry, and we are not alone, says RSPB chief executive Beccy Speight

Tom Mustill's How to Speak Whale and Karen Bakker's The Sounds of Life explore what we know about the way life on Earth communicates, from whales to coral reefs. They are both must-reads
