Local decision-makers looking for ways to reduce the impact of heat waves on their communities have a valuable new capability at their disposal: a new study on vegetation resilience. Scientists completed a study of how well vegetation survived extreme heat events in both urban and rural communities across the country...
Swarms of miniature robots clean up microplastics and microbes, simultaneously
When old food packaging, discarded children's toys and other mismanaged plastic waste break down into microplastics, they become even harder to clean up from oceans and waterways. These tiny bits of plastic also attract bacteria, including those that cause disease. Researchers describe swarms of microscale robots (microrobots) that captured bits...
Why is breaking down plant material for biofuels so slow?
Tracking individual enzymes during the breakdown of cellulose for biofuel production has revealed how several roadblocks slow this process when using plant material that might otherwise go to waste. The research may lead to new ways to improve the breakdown process and make the non-edible parts of plants and other...
It flickers, then it tips — study identifies early warning signals for the end of the African humid period
Tipping points in the climate system can be the result of a slow but linear development. However, they can also be accompanied by a 'flickering', with two stable climatic states that alternate before a final transition occurs -- and the climate tips permanently.
US geographic region results in vastly different anal cancer risk for people with HIV
For people with HIV, the risk of anal cancer varies according to their geographic region.
Efficacy of solar panels boosted
Solar energy is a crucial asset in the fight against climate change, and researchers have now devised a smart approach to optimize its effectiveness. Their innovative method includes incorporating artificial ground reflectors, a simple yet powerful enhancement.
Surviving Ash Trees May Hold Key to Saving Multiple Species of the Trees
The invasive insect emerald ash borer is killing ash trees at an unprecedented rate in the United States, and now five North American species of ash are considered critically endangered, according to the U.S. Department of Agriculture (USDA) Forest Service.
Unraveling the Mysteries of Consecutive Atmospheric River Events
In California’s 2022-2023 winter season, the state faced nine atmospheric rivers (ARs) that led to extreme flooding, landslides, and power outages – the longest duration of continuous AR conditions in the past 70 years.
The Future of Coral Restoration in the Florida Keys After Unprecedented Marine Heat Wave of 2023
In the summer of 2023, portions of the Florida Keys experienced an extreme marine heat wave, unlike any other in recorded history for the region.
Origin of Roman lead
Three ingots from the site of Los Escoriales de Do a Rama (Belmez) and dating from the Roman era demonstrate the importance of lead production and exportation in northern Cordoba.
