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.

The medicinal secrets of the Chilean soapbark tree have been laid bare, unlocking a future of more potent, affordable, and sustainably sought vaccines. Researchers have taken a major step forward in addressing this problem, by using a combination of genome mining and bioengineering techniques to produce saponin-based vaccine adjuvants in the laboratory without harvesting material directly from trees.

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.

Researchers have discovered how a South African daisy makes fake lady flies on its petals to trick male flies into pollinating it.

Research has revealed that diversity in genes coding for immunity may have facilitated adaptation to farming lifestyles in prehistoric periods.

Microplastic pollution reduces energy production in a microscopic creature found in freshwater worldwide, new research shows.

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.

The impact of multi-story building design considerations on embodied carbon emissions, cost, and operational energy has been revealed.

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.

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.

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.

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.

Some plants can survive months without water, only to turn green again after a brief downpour. A recent study shows that this is not due to a 'miracle gene.' Rather, this ability is a consequence of a whole network of genes, almost all of which are also present in more vulnerable varieties.

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.

The first study into the biological response of the upper ocean in the wake of South Pacific cyclones could help predict the impact of warming ocean temperatures, researchers believe.

Scientists have created a comprehensive 'roadmap' to guide global efforts to convert waste energy into clean power.

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.

     (via sciencedaily.com) 

By combining lab experiments and mathematical modelling, researchers have found a way to predict the movement of species that could guide conservation efforts to reconnect fragmented habitats.

Engineers have developed a new water treatment that removes 'forever chemicals' from drinking water safely, efficiently -- and for good.

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.
