For tens of thousands of years, Aboriginal Australians have created some of the world's most striking artworks. Today their work continues long lines of ancestral traditions, stories of the past and connections to current cultural landscapes, which is why researchers are keen on better understanding and preserving the cultural heritage...
Autonomous underwater imaging: Faster and more accurate
Recently conducted tests used new algorithms to outperform state-of-the-art programming for autonomous underwater sonar imaging, significantly improving the speed and accuracy for identifying objects such as explosive mines, sunken ships, airplane black boxes, pipelines and corrosion on ship hulls.
How to tie-dye cotton with acorns and rust
Tie-dyeing is a fun activity that can spice up clothes with colorful patterns. Although kits are available in stores, nature provides dyes that can be extracted from items found in one's yard -- for example, acorns and rust. Researchers now present a 'green' process for tie-dyeing cotton with renewable resources...
Discovery offers starting point for better gene-editing tools
New research has big implications for genomic medicine. Scientists have defined with atomic precision a new genome editing tool that is less than half the size of CRISPR-Cas9 -- currently the most reliable genome editing system. This new tool would allow scientists to fit genetic editors into smaller viral delivery...
Pacific Northwest National Laboratory Plans Transition to Net-Zero Greenhouse Gas Emissions
From buildings, to transportation, to electricity generation and energy storage, Pacific Northwest National Laboratory has long been a leader in providing clean energy solutions.
Arc volcanoes are wetter than previously thought, with scientific and economic implications
This increased amount of water has broad implications for understanding how Earth's lower crust forms, how magma erupts through the crust, and how economically important mineral ore deposits form, according to a new article
Producers and consumers must share burden of global plastic packaging waste
Plastic packaging waste is everywhere. Our plastic bottles, food wrappings, and grocery bags litter the landscape and pollute the global environment. A new study explores the global patterns of plastic packaging waste. The study finds three countries -- the U.S., Brazil, and China -- are the top suppliers of waste.
A unique catalyst paves the way for plastic upcycling
A recently developed catalyst for breaking down plastics continues to advance plastic upcycling processes. In 2020, scientists developed the first processive inorganic catalyst to deconstruct polyolefin plastics into molecules that can be used to create more valuable products. Now, the team has developed and validated a strategy to speed up...
Wealthiest homeowners most at risk of wildfire hazard
The top ten per cent most valuable homes in the western United States are 70% more likely to be in high wildfire hazard areas than median-value properties, according to a new study.
People must be ‘heart’ of climate action
Tackling the climate crisis can only be achieved by 'placing people at the heart of climate action', researchers say.
