Anthropogenic climate change accelerating faster than earlier, natural analogs
Whilst large-scale volcanic activity has been responsible for huge temperature rises millions of years ago, human-made climate change is happening at a far faster rate.
Ecologists sound alarm on plastic pollution
Unless growth in plastic production and use is halted, a fundamental transformation of the plastic economy to a framework based on recycling is essential.
Cement made from plant oil and waste sulfur
Researchers combine waste vegetable oil and sulfur to create an eco-friendly, sturdy and lightweight cement substitute that can be remelted as often as desired.
Compressed air cars for urban transportation
Researchers have increased the efficiency of compressed air cars with the aid of phase change materials for heat recovery, making them a viable carbon-free alternative for future passenger cars.
Giant hornet: Potential spread and impact on honeybees
Spread of the giant Asian hornet (Vespa mandarinia) in the USA threatens honeybee colonies, and new analysis assesses the possible impact.
The effects of ocean warming
Marine biologist Ian Bouyoucos investigated blacktip reef sharks in French Polynesia. In this interview, he reveals that not everything in this paradise is as it should be thanks to climate change.
Dual aluminum-nitrogen battery that stores energy and fixes nitrogen
A rechargeable aluminum-nitrogen battery serves the dual purpose of not only storing and retrieving energy, but also being able to fix its nitrogen stream as ammonia.
Towards long-lasting lithium-sulfur batteries
A new titanium nitride sulfur composite reduces the notorious shuttle effect and improves the overall performance of lithium-sulfur batteries.
Micro- and nanoplastics detectable in human tissues
A new study is the first to examine micro- and nanoplastic occurrence in human organs, providing the first clues on potential exposure sources and routes.
The temporal politics and ethics of hydropower development in the Himalayas
As hydropower projects are built across the Himalayan region, recognizing the temporal politics inherent to hydropower development will become increasingly critical.
A new design for better redox flow batteries
A new design for vanadium redox flow batteries could help fundamental research and accelerate commercialization of this energy storage technology.
