From droughts and forest fires to floods and big freezes, extreme weather events are on the rise. But to what extent are these linked to climate change? Just months before the world’s first wind monitoring satellite enters orbit, scientists have finalised a climate model with exceptional resolution, and the new tools will help identify how climate change impacts weather-related natural disasters like storm surges, hurricanes and heatwaves.
A theory developed with the late Professor Stephen Hawking stating that the universe is more simple and uniform than current models suggest was so shocking that it had to be sat on for a while before it was released to the world, according to co-author Professor Thomas Hertog from KU Leuven in Belgium.
The world’s largest radio telescope, known as the Square Kilometre Array (SKA) and situated over two continents, will be able to detect the first stars and galaxies emerging from the ‘murk’ at the beginning of the universe and much more besides, according to Professor Phil Diamond, Director General of SKA.He spoke to Horizon at the opening of the Shared Sky art exhibition in Brussels, Belgium on 16 April, where indigenous artists from SKA host nations South Africa and Australia use traditional painting and folk art to explore the themes of astronomy, spirituality and a borderless sky.
The search for alien life with next-generation telescopes, a self-healing heart capable of restarting itself, and safer roads with smarter cars are expected to feature as the some of the key scientific breakthroughs in the coming year.
Understanding more about how solar storms interact with the outermost part of Earth's environment, known as the foreshock, could refine space weather forecasts to predict their effects at a local level and help protect vital technology, according to Dr Lucile Turc, a space physicist at the University of Helsinki, Finland.
Orbiting the sun from far beyond planet Neptune, the recently discovered planetoid Haumea is a fast-spinning elongated object, completing one rotation every four hours. Now, following fresh observations, astronomers have discovered this dwarf planet also has a ring system in orbit around it.
It's easy to picture a black hole as a kind of all-powerful cosmic drain, a sinkhole of super-strong gravity that snags and swallows passing nebulae or stars. While it is true we can’t observe matter once it crosses a black hole’s event horizon, scientists are zeroing in on what happens in the margins, where molecular clouds release vast amounts of energy as it circles the plughole.
A circular economy needs new business models and reusable products, says Felipe Maya.
The first step in limiting global warming should be curbing energy demand, says Dr Keywan Riahi.
Professor Eva Hevia talks about chemistry’s green movement.
