Published New Nevada experiments will improve monitoring of nuclear explosions



On an October morning in 2023, a chemical explosion detonated in a tunnel under the Nevada desert was the launch of the next set of experiments by the National Nuclear Security Administration, with the goal to improve detection of low-yield nuclear explosions around the world.
Published New eco-friendly lubricant additives protect turbine equipment, waterways



Scientists have developed lubricant additives that protect both water turbine equipment and the surrounding environment.
Published Oil palm plantations are driving massive downstream impact to watershed



The global demand for palm oil -- the most widely consumed vegetable oil on the planet, in everything from instant noodles to lipstick -- is driving worldwide tropical deforestation. While many studies have shown the loss of biodiversity when rainforests are converted to oil palm plantations, researchers have now shown the far-reaching and wide-ranging disturbances to the watersheds in which such plantations occur.
Published Human activity is causing toxic thallium to enter the Baltic sea, according to new study



Human activities account for 20% to more than 60% of toxic thallium entering the Baltic Sea over the past eight decades, according to new research. Currently, the amount of thallium, which is considered the most toxic metal for mammals, remains low in Baltic seawater. Much of the thallium in the Baltic, which is the largest human-induced hypoxic area on Earth, has been accumulated in the sediment thanks to sulfide minerals.
Published Path to easier recycling of solar modules



The use of femtosecond lasers to form glass-to-glass welds for solar modules would make the panels easier to recycle, according to a proof-of-concept study.
Published Robots invited to help make wind turbine blades



Researchers have successfully leveraged robotic assistance in the manufacture of wind turbine blades, allowing for the elimination of difficult working conditions for humans and the potential to improve the consistency of the product.
Published Wildfires in wet African forests have doubled in recent decades



Climate change and human activities like deforestation are causing more fires in central and west Africa's wet, tropical forests, according to the first-ever comprehensive survey there. The fires have long been overlooked.
Published Sugar-based catalyst upcycles carbon dioxide



New catalyst is made from an inexpensive, abundant metal and table sugar. Catalyst converts carbon dioxide (CO2) into carbon monoxide, a building block for producing a variety of useful chemicals including syngas. With recent advances in carbon capture technologies, post-combustion carbon capture is becoming a plausible option to help tackle the global climate change crisis. But how to handle the captured carbon remains an open-ended question. The new catalyst potentially could provide one solution for disposing the potent greenhouse gas by converting it into a more valuable product.
Published To bend the curve of biodiversity loss, nature recovery must be integrated across all sectors



The alarming rates of biodiversity loss worldwide have made clear that the classical way of governing biodiversity recovery based on protected areas and programs for the protection of endangered species is not enough. To tackle this, almost 200 countries committed to the active 'mainstreaming' or integration of biodiversity targets into policies and plans across relevant sectors. However, research suggests that this has until now been largely ineffective due to non-binding commitments, vaguely formulated targets, 'add-on' biodiversity initiatives, and too few resources. 'Top down regulation is also needed,' say the authors.
Published Artificial intelligence enhances monitoring of threatened marbled murrelet



Artificial intelligence analysis of data gathered by acoustic recording devices is a promising new tool for monitoring the marbled murrelet and other secretive, hard-to-study species.
Published EPA underestimates methane emissions from landfills, urban areas



The Environmental Protection Agency (EPA) is underestimating methane emissions from landfills, urban areas and U.S. states, according to a new study. The researchers combined 2019 satellite observations with an atmospheric transport model to generate a high-resolution map of methane emissions, which was then compared to EPA estimates from the same year. The researchers found: Methane emissions from landfills are 51% higher compared to EPA estimates Methane emissions from 95 urban areas are 39% higher than EPA estimates Methane emissions from the 10 states with the highest methane emissions are 27% higher than EPA estimates.
Published New computer algorithm supercharges climate models and could lead to better predictions of future climate change



A study describes a new computer algorithm which can be applied to Earth System Models to drastically reduce the time needed to prepare these in order to make accurate predictions of future climate change. During tests on models used in IPCC simulations, the algorithm was on average 10 times faster at spinning up the model than currently-used approaches, reducing the time taken to achieve equilibrium from many months to under a week.
Published Roadmap to close the carbon cycle



Reaching net-zero carbon emissions goals requires finding transformative paths to manage carbon in difficult-to-electrify economic sectors.
Published Calcium can protect potato plants from bacterial wilt



Scientists have discovered that calcium plays a significant role in enhancing the resistance of potato plants to bacterial wilt.
Published Every breath you take: Study models the journey of inhaled plastic particle pollution



With recent studies having established the presence of nano and microplastic particles in the respiratory systems of both human and bird populations, new research has modeled what happens when people breathe in different kinds of plastic particles and where they end up.
Published New Japanese lily species identified, 1st addition to sukashiyuri group in 110 years



For the first time since 1914, a new species of the Japanese lily known as sukashiyuri has been identified. A research team analyzed the morphology and DNA of these lilies and has revised the conventional classification from four taxonomic groups to eight.
Published Novel genetic plant regeneration approach without the application of phytohormones



Conventional plant regeneration approaches by cell culture require the external application of plant growth regulators, including hormones. However, optimizing culture conditions can be laborious. Now, researchers have developed a novel plant regeneration system that omits the need for hormone application by genetically regulating the expression of genes that control plant cell differentiation. Their work holds significant potential in the development of genetically modified plants in a simpler and cost-effective manner.
Published Activity in a room stirs up nanoparticles left over from consumer sprays



Common household products containing nanoparticles -- grains of engineered material so miniscule they are invisible to the eye -- could be contributing to a new form of indoor air pollution, according to a new study.
Published Astronomers share climate-friendly meeting solutions



Carbon emissions associated with air travel to professional conferences make up a sizable fraction of the emissions produced by researchers in academia.
Published Missing link in species conservation: Pharmacists, chemists could turn tide on plant, animal extinction



As the world faces the loss of a staggering number of species of animals and plants to endangerment and extinction, one scientist has an urgent message: Chemists and pharmacists should be key players in species conservation efforts.
