‘Big, bad wolf’ image flawed – scientists

Image copyright Rooobert Bayer Image caption Wolves are good at working together to get food rewards New research casts doubt on the idea that dogs are naturally more tolerant and friendly than wolves.

Nasa carbon space observatory ‘watches Earth breathe’

Media captionAn animation depicts changes in atmospheric CO2 through the year A Nasa satellite has provided remarkable new insights on how CO2 is moved through the Earth’s atmosphere. The Orbiting Carbon Observatory (OCO) tracked the behaviour of the gas in 2015/2016 – a period when the planet experienced a major El NiƱo event. This climate […]

How do you build the next-generation internet?

How do you build the next-generation internet?

Image copyright Getty Images Image caption Scientists are now developing an ultra-fast quantum internet that will be partly based on light Imagine super-fast computers that can solve problems much quicker than machines today. These “quantum computers” are being developed in laboratories around the world. But scientists have already taken the next step, and are thinking […]

Ozone layer recovery could be delayed by 30 years

Ozone layer recovery could be delayed by 30 years

Image copyright SPL Image caption Researchers reported in 2015 that there was clear evidence of healing in the ozone hole Rising global emissions of some chlorine-containing chemicals could slow the progress made in healing the ozone layer. A study found the substances, widely used for paint stripping and in the manufacture of PVC, are increasing […]
