Weeding robots can sometimes struggle to tell weeds from crops, but genetically modifying the plants we want to keep to make them brightly coloured would make the job easier, suggest a group of researchers

Investigations of the paradoxical link between tinnitus and hearing loss have revealed a hidden form of deafness, paving the way to possible new treatments

Up to 17 US states could be peppered with more than a trillion cicadas this spring, and though it has been a while since these two specific broods emerged at once, double broods are not that rare

Ground-up concrete can remove carbon dioxide from the atmosphere in a similar way to ground-up rocks, according to a field study in Ireland

We know little about how embryonic development in animals evolved from single-celled ancestors, but simple organisms with a multicellular life stage offer intriguing clues

A serendipitous lab accident revealed that hibernating bumblebee queens can make it through days of flooding, revealing that they are less vulnerable to extreme weather than previously thought

Starfish feet are coordinated purely through mechanical loading, enabling the animals to bounce rhythmically along the seabed without a central nervous system

Traditional economics makes ludicrous assumptions and poor predictions. Now an alternative approach using big data and psychological insights is proving far more accurate

Modelling that shows how the world can remain below 1.5°C of warming assumes we can store vast amounts of carbon dioxide underground, but a new analysis reveals that achieving this is extremely unlikely

A black hole would be tough to destroy, but in the season two premiere of Dead Planets Society our hosts are willing to go to extremes, from faster-than-light bombs to time travel

Remote-controlled cockroaches with computers mounted on their backs can move as a swarm towards a target location, and could be used for search missions

A black hole 33 times the mass of the sun is the largest stellar black hole ever spotted, and its strange companion star could help explain how it got so huge
