Published Global natural history initiative builds groundbreaking database to address 21st century challenges
(via sciencedaily.com) 
A group of natural history museums has mapped the total collections from 73 of the world's largest natural history museums in 28 countries. This is the first step of an ambitious effort to inventory global holdings that can help scientists and decision makers find solutions to urgent, wide-ranging issues such as climate change, food insecurity, human health, pandemic preparedness, and wildlife conservation.
Published The global economics of climate action
(via sciencedaily.com) 
Climate change has serious consequences for the environment and people and is a major threat to economic stability. A new assessment reviews innovative, integrated research that underpins the economic case for strong near-term climate action.
Published Microplastics limit energy production in tiny freshwater species
(via sciencedaily.com) 
Microplastic pollution reduces energy production in a microscopic creature found in freshwater worldwide, new research shows.
Published Improved wastewater treatment could lead to significant reduction in greenhouse gas emissions
(via sciencedaily.com) 
New research has shown that methane emissions from urban areas are underestimated by a factor of three to four and that untreated wastewater may be a contributing factor.
Published What really matters in multi-story building design?
(via sciencedaily.com) 
The impact of multi-story building design considerations on embodied carbon emissions, cost, and operational energy has been revealed.
Published At least 80% of the world's most important sites for biodiversity on land currently contain human developments
(via sciencedaily.com) 
At least 80% of sites identified as being internationally important for biodiversity on land currently contain infrastructure -- of which more than 75% contain roads. In the future, more sites that are important for biodiversity could contain powerplants, mines and oil and gas infrastructure.
Published Closed loop for circular economy: New polymer recycling strategy ensures both high stability and complete recyclability
(via sciencedaily.com) 
Large amounts of plastic waste are incinerated or deposited in landfills. This degrades the environment and depletes valuable resources. In this light, recycling plastics such as polymers is promising. However, recycling diminishes their quality. Recently, researchers have proposed a 'closed-loop' recycling process based on polymer microparticles. It produces fully recyclable polymer films with high mechanical stability and fracture energy, which they retain upon recycling.
Published New wood-based technology removes 80% of dye pollutants in wastewater
(via sciencedaily.com) 
Researchers have developed a new method that can easily purify contaminated water using a cellulose-based material. This discovery could have implications for countries with poor water treatment technologies and combat the widespread problem of toxic dye discharge from the textile industry.
Published Pressure-based control enables tunable singlet fission materials for efficient photoconversion
(via sciencedaily.com) 
Applying hydrostatic pressure as an external stimulus, researchers demonstrate a new way to regulate singlet fission (SF), a process in which two electrons are generated from a single photon, in chromophores, opening doors to the design of SF-based materials with enhanced (photo)energy conversion. Their method overrides the strict requirements that limit the molecular design of such materials by realizing an alternative control strategy.
Published Without this, plants cannot respond to temperature
(via sciencedaily.com) 
Scientists have significantly advanced the race to control plant responses to temperature on a rapidly warming planet. Key to this breakthrough is miRNA, a molecule nearly 200,000 times smaller than the width of a human hair.
Published Drought, heat waves worsen West Coast air pollution inequality
(via sciencedaily.com) 
A new study found drought and heat waves could make air pollution worse for communities that already have a high pollution burden in California, and deepen pollution inequalities along racial and ethnic lines. The study also found financial penalties for power plants can significantly reduce people's pollution exposure, except during severe heat waves.
Published Robotic system offers hidden window into collective bee behavior
(via sciencedaily.com) 
Researchers have developed a temperature-modulating robotic system that can be seamlessly integrated into notoriously sensitive honeybee hives, providing both a never-before-seen view of honeybee behavior and a means to influence it.
Published Global experts propose a path forward in generating clean power from waste energy
(via sciencedaily.com) 
Scientists have created a comprehensive 'roadmap' to guide global efforts to convert waste energy into clean power.
Published Road noise makes your blood pressure rise -- literally
(via sciencedaily.com) 
If you live near a busy road you might feel like the constant sound of roaring engines, honking horns and wailing sirens makes your blood pressure rise. Now a new study confirms it can do exactly that.
Published Copper artifacts unearth new cultural connections in southern Africa
(via sciencedaily.com) 
Chemical and isotopic analysis of artifacts from southern Africa called copper ingots reveals new cultural connections among people living in the region between the 5th and 20th centuries.
Published Babies or beauty? Ancient origin of how female butterflies invest
(via sciencedaily.com) 
When resources are scarce, most animals have to choose. A new study reveals an ancient origin to how female butterflies invest.
Published New water treatment zaps 'forever chemicals' for good
(via sciencedaily.com) 
Engineers have developed a new water treatment that removes 'forever chemicals' from drinking water safely, efficiently -- and for good.
Published Photosynthesis 'hack' could lead to new ways of generating renewable energy
(via sciencedaily.com) 
Researchers have 'hacked' the earliest stages of photosynthesis, the natural machine that powers the vast majority of life on Earth, and discovered new ways to extract energy from the process, a finding that could lead to new ways of generating clean fuel and renewable energy.
Published Sea ice will soon disappear from the Arctic during the summer months -- and it has happened before
(via sciencedaily.com) 
In a new study, an international team of researchers warn that the Arctic Sea ice may soon be a thing of the past in the summer months. This may have consequences for both the climate and ecosystems. Ten thousand years ago, the ice melted at temperatures similar to those we have today.
Published Mercury emission estimates rarely provide enough data to assess success in eliminating harmful global gold mining practice
(via sciencedaily.com) 
A global treaty called the Minamata Convention requires gold-mining countries to regularly report the amount of toxic mercury that miners are using to find and extract gold, designed to help nations gauge success toward at least minimizing a practice that produces the world's largest amount of manmade mercury pollution.
