Combining two semiconductor thin films into a tandem solar cell can achieve high efficiencies with a minimal environmental footprint. Teams have now presented a CIGS-perovskite tandem cell that sets a new world record with an efficiency of 24.6%, certified by an independent body.
New study model with clues to anti-aging
Scientists have created genetically-engineered mice that could help accelerate anti-aging research.
Why do plants transport energy so efficiently and quickly?
Photosynthesis -- mainly carried out by plants -- is based on a remarkably efficient energy conversion process. To generate chemical energy, sunlight must first be captured and transported further. This happens practically loss-free and extremely quickly. A new study shows that quantum mechanical effects play a key role in this...
How healthy stem cells turn into oral cancer
Researchers have identified the molecular and cellular mechanisms that transform healthy stem cells into oral cancer at the earliest stages of the disease.
New device uses electrically assisted wind to fight fires
Researchers have developed a new portable tool that could improve how firefighters douse fires, making the process more efficient and far less risky.
Half a degree further rise in global warming will triple area of Earth too hot for humans
New assessment warns area the size of the USA will become too hot during extreme heat events for even healthy young humans to maintain a safe body temperature if we hit 2 degrees Celsuis above preindustrial levels. For those aged over 60, the same 2 degree rise would see more...
New study assesses impact of agricultural research investments on biodiversity, land use
New, groundbreaking research shows how, at a local scale, agricultural research and development led to improved crop varieties that resulted in global benefits to the environment and food system sustainability.
The cost of preventing extinction of Australia’s priority species
A new study has estimated it would cost $15.6 billion per year for 30 years to prevent extinction for 99 of Australia's priority species. The research highlights the urgent need for increased funding to combat threats such as habitat destruction, invasive species and climate change.
New research on ancient life found in Yellowstone hot springs
New work offers insight into how early life adapted from a low-oxygen atmosphere to the one that exists today.
Discovery of water droplet freezing bridges atmospheric science, climate solutions
A groundbreaking study on the freezing of water droplets suspended in air sheds light on a key process in Earth's water cycle: the transformation of supercooled water into ice.
