By harnessing the power of strong winds at higher altitude than turbines reach, airborne wind energy could be another key source of renewable energy, but it will need a combination of successful designs, more robust software and good storytelling to really take off.
By 2030, a fifth of the fuel that motorists put into the petrol tanks of their cars could be alcohol, according to research concluding that new petrol and ethanol blends can reduce carbon emissions from Europe’s transport sector with little additional cost to consumers.
There is a certain romance to speleology, the study of caves, if you can see past the cold and the damp and the dark. Caves are ancient and often beautiful places. And they can be useful. Rock formations in caves, it turns out, hold within them chemical secrets that provide a window on both ancient civilisations and the climate of the future.
Male seahorses not only become pregnant and give birth, but do so in ways that take different forms, which make them unique research subjects to understand the evolution of pregnancy, according to Dr Olivia Roth from the Helmholtz Centre for Ocean Research Kiel (GEOMAR) in Germany.
Fragrant aromas from plants can actually be a response to attacks by insects, and can alert neighbours to an attack or summon the insects’ predators. Now, scientists are deciphering these secret codes to develop better, greener chemicals to defend crops against herbivorous insects.
Delivering online shopping to people’s homes is a huge source of greenhouse gas emissions, particularly when deliveries fail and the journey needs to be repeated. Researchers are now re-thinking home deliveries to see if there is a better way of doing things, with ideas including robot couriers, jointly owned parcel lockers and an ‘Uber’ for parcels.
The brown bear is one of Europe’s five large carnivores and can sometimes cross paths with people, with potentially fatal consequences. But bears have different personalities and behaviours, say researchers, and understanding this is the key to reducing conflict and protecting both them and humans.
A fine layer of dust thought to have been left by the first winter monsoon ever to cross northeastern Tibet has been uncovered by scientists, revealing the moment when the great weather phenomenon that waters much of Asia’s summers and dries its winters may have begun.
Across Europe’s cities, the demand for delivery services is increasing. But these deliveries affect urban life as they add to traffic congestion, noise and pollution and many cities are now trying out alternative modes of transport that could help.
Scientists are developing a pipeline to churn out remedies for almost any newly emerging virus.
Airborne energy systems aim to capitalise on the stronger winds at high altitudes.
The more satellite launches we do, the bigger the risk of damage or debris, says Dimitra Stefoudi.
