Scientists have developed a novel triple-junction perovskite/Si tandem solar cell that can achieve a certified world-record power conversion efficiency of 27.1 per cent across a solar energy absorption area of 1 sq cm, representing the best-performing triple-junction perovskite/Si tandem solar cell thus far. To achieve this, the team engineered a...
New research shows migrating animals learn by experience
Individual white storks incrementally straightened their migration routes to find more direct ways to move between destinations during the spring migration to summer breeding and nesting grounds, suggesting that experiential learning is an important part of successful migration.
Protecting joints from bacteria with mussels
A collaborative team of researchers developed an implant coating triggering antibiotic release in response to bacterial infection.
Unraveling the mystery of chiton visual systems
You'd probably walk past a chiton without even seeing it. These creatures often look like nothing more than another speck of seaweed on the crusty intertidal rocks. But it sees you. At least, if it's one of the species with eyes dotting its platemail shell.
A model for the evolution of intelligence
When certain species of wild birds and primates discover new ways of finding food in the wild, it can serve to measure their flexibility and intelligence. In the largest experimental study ever conducted on this topic, researchers have shown that foraging problems requiring overcoming obstacles, such as removing the lid...
An evolutionary mystery 125 million years in the making
Plant biologists have uncovered an evolutionary mystery over 100 million years in the making. It turns out that sometime during the last 125 million years, tomatoes and Arabidopsis thaliana plants experienced an extreme genetic makeover. Just what happened remains unclear. But the mystery surrounds CLV3, a gene key to healthy...
2020 extreme weather event that brought fires and snow to western US
The same weather system that led to the spread of the devastating Labor Day wildfires in 2020 brought record-breaking cold and early-season snowfall to parts of the Rocky Mountains. Now, new research is shedding light on the meteorology behind what happened and the impacts of such an extreme weather event.
Orcas demonstrating they no longer need to hunt in packs to take down the great white shark
An orca (killer whale) has been observed, for the first-ever time, individually consuming a great white shark -- and within just two minutes.
Study identifies multi-organ response to seven days without food
New findings reveal that the body undergoes significant, systematic changes across multiple organs during prolonged periods of fasting. The results demonstrate evidence of health benefits beyond weight loss, but also show that any potentially health-altering changes appear to occur only after three days without food.
Researchers create coating solution for safer food storage
Galvanized steel containers and surfaces are used for harvested produce because of their durability, strength and lower cost compared to stainless steel. However, bacteria residing in storage containers can cause corrosion. The new coating will reduce corrosion by at least 70 percent, researchers say.
