Engineers have developed a new kind of membrane that separates chemicals within wastewater so effectively that they can be reused, presenting a new opportunity for industries to improve sustainability, while extracting valuable by-products and chemicals from wastewater.

A research team recently developed a stable artificial photocatalytic system that is more efficient than natural photosynthesis. The new system mimics a natural chloroplast to convert carbon dioxide in water into methane, a valuable fuel, very efficiently using light. This is a promising discovery, which could contribute to the goal of carbon neutrality.

Researchers have sequenced the complete genome for einkorn wheat, the world's first domesticated crop and traced its evolutionary history. The information will help researchers identify genetic traits like tolerance to diseases, drought and heat, and re-introduce those traits to modern bread wheat.

A new image of the galaxy cluster known as 'El Gordo' is revealing distant and dusty objects never seen before, and providing a bounty of fresh science. The infrared image displays a variety of unusual, distorted background galaxies that were only hinted at in previous Hubble Space Telescope images.

Researchers have analyzed the shifting patterns of entire dune fields on Earth and Mars, as seen from orbit, and found they are a direct signature of recent environmental change. This new tool can be applied anywhere with dunes, such as Mars, Titan, and Venus.

An evaluation of 17 previously published studies suggests that exposure to lead in the womb or in childhood is associated with an increased risk of engaging in criminal behavior in adulthood -- but more evidence is needed to strengthen understanding.

The closure in January 2016 of one of Pittsburgh's biggest coal-processing plants led to immediate and lasting declines in emissions of fossil fuel-related air pollutants. These in turn were linked to near-instant decreases in local heart-related emergency department visits and hospitalizations for cardiovascular diseases, a new study shows. The impact of the closure persisted through at least December 2018, the last month for which data were analyzed.

Moving to more polluted areas was associated with an increase in body mass index, according to an analysis of more than 46,000 children and adolescents living in Catalonia.

Nature-based solutions (NBS) can help grand challenges, such as climate change and food security, but, as things stand, communities outside of Europe do not stand to benefit from these innovations. New research has found that more than 60% of NBS are located in Europe, with other regions showing poor use of the technologies.

Researchers have revealed the unique 'cheating' strategy a New Zealand insect has developed to avoid being eaten -- mimicking a highly toxic species.

Major government and private funding is being invested in planting trees as a powerful tool to fight climate change. But new research shows a troubling bottleneck that could threaten these efforts: U.S. tree nurseries don't grow close to enough trees--nor have the species diversity needed--to meet ambitious planting and restoration goals.

Researchers offer insight into the source of cosmic magnetic fields. The research team used models to show that magnetic fields may spontaneously arise in turbulent plasma. Their simulations showed that, in addition to generating new magnetic fields, the turbulence of those plasmas can also amplify magnetic fields once they've been generated, which helps explain how magnetic fields that originate on small scales can sometimes eventually reach to stretch across vast distances.

An asteroid discovery algorithm -- designed to uncover near-Earth asteroids for the Vera C. Rubin Observatory's upcoming 10-year survey of the night sky -- has identified its first 'potentially hazardous' asteroid, a term for space rocks in Earth's vicinity that scientists like to keep an eye on. The roughly 600-foot-long asteroid, designated 2022 SF289, was discovered during a test drive of the algorithm with the ATLAS survey in Hawaii. Finding 2022 SF289, which poses no risk to Earth for the foreseeable future, confirms that the next-generation algorithm, known as HelioLinc3D, can identify near-Earth asteroids with fewer and more dispersed observations than required by today's methods.

The dry summer of 2018 hit Swedish forests hard -- and hardest affected were the managed secondary forests.

In past ice ages, the intensity of summer insolation affected the emergence of warm and cold periods and played an important role in triggering abrupt climate changes, a study by climate researchers, geoscientists, and environmental physicists suggests. Using stalagmites in the European Alps, they were able to demonstrate that warm phases appeared primarily when the summer insolation reached maxima in the Northern Hemisphere.
