The most cost-effective climate change actions are also those that could help us achieve sustainable development goals (SDGs) such as ending poverty and hunger, according to Dr Keywan Riahi, director of the energy program of the International Institute Applied Systems Analysis (IIASA) in Austria, who says the first step should be to cut our energy demand.
From about 245 to 66 million years ago, dinosaurs roamed the Earth. Although well-preserved skeletons give us a good idea of what they looked like, the way their limbs worked remains a bigger mystery. But computer simulations may soon provide a realistic glimpse into how some species moved and inform work in fields such as robotics, prosthetics and architecture.
Thousands of soiled nappies that were destined to clog Italian landfill sites or incinerators are being redirected to a recycling plant that is turning them into streams of high quality raw materials, in a new process that it is hoped will be replicated around Europe.
Seaweed has long been touted for its potential as a sustainable ingredient for biofuels, green chemicals and biodegradable materials, but scaling up production to industrial levels in a way that maintains its environmental credentials is proving a real challenge for scientists.
We may never be able to entirely predict earthquakes such as those that hit central Italy in 2016, but we could better assess how they’re going to play out by joining up data from different scientific fields in a new Europe-wide observatory, say scientists.
The air in our offices and homes can contain a higher mix of chemicals than outdoors, but next-generation purifiers - including one that uses plants as natural biofilters and another that turns pollutants into water and carbon dioxide - are aiming to absorb the harmful particles and let us all breathe a bit easier.
It was a life-altering event. Around 66 million years ago, at the end of the Cretaceous period, an asteroid struck the Earth, triggering a mass extinction that killed off the dinosaurs and some 75% of all species. Somehow mammals survived, thrived, and became dominant across the planet. Now we have new clues about how that happened.
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.
