Published New study disputes Hunga Tonga volcano's role in 2023-24 global warm-up



New research is exploring the climate impact of the 2022 Hunga Tonga volcano eruption and challenging existing assumptions about its effects in the process.
Published Thousands of birds and fish threatened by mining for clean energy transition, study finds



Our increasing demand for metals and minerals is putting over four thousand vertebrate species at risk, with the raw materials needed for clean energy infrastructure often located in global biodiversity hotspots, a study has found.
Published Folded peptides are more electrically conductive than unfolded peptides



What puts the electronic pep in peptides? A folded structure, according to a new study. Researchers combined single-molecule experiments, molecular dynamics simulations and quantum mechanics to validate the findings.
Published 'Kink state' control may provide pathway to quantum electronics



The key to developing quantum electronics may have a few kinks. According to researchers, that's not a bad thing when it comes to the precise control needed to fabricate and operate such devices, including advanced sensors and lasers. The researchers fabricated a switch to turn on and off the presence of kink states, which are electrical conduction pathways at the edge of semiconducting materials.
Published Nitrogen emissions have a net cooling effect: But researchers warn against a climate solution



An international team of researchers has found that nitrogen emissions from fertilizers and fossil fuels have a net cooling effect on the climate. But they warn increasing atmospheric nitrogen has further damaging effects on the environment, calling for an urgent reduction in greenhouse gas emissions to halt global warming.
Published Quantum sensor for the atomic world



In a scientific breakthrough, an international research team has developed a quantum sensor capable of detecting minute magnetic fields at the atomic length scale. This pioneering work realizes a long-held dream of scientists: an MRI-like tool for quantum materials.
Published Great Salt Lake a significant source of greenhouse gas emissions



Newly announced research examining greenhouse gas emissions from the drying lake bed of Great Salt Lake, Utah, calculates that 4.1 million tons of carbon dioxide and other greenhouse gases were released in 2020. This research suggests that drying lake beds are an overlooked but potentially significant source of greenhouse gases, which may further increase due to climate change.
Published A recipe for zero-emissions fuel: Soda cans, seawater, and caffeine



Engineers discovered that when the aluminum in soda cans is purified and mixed with seawater, the solution produces hydrogen -- which can power an engine or fuel cell without generating carbon emissions. The reaction can be sped up by adding caffeine.
Published Scientists study how to bring you 'climate-smart coffee'



Coffee beans consumed across the globe come from two species: Coffea arabica and Coffea canephora. By 2050, about 80% of Arabica production is predicted to decrease because of climate change. Researchers are investigating to see if they can find alternative coffee cultivars.
Published Better way to produce green hydrogen



Researchers have developed a material that shows a remarkable ability to convert sunlight and water into clean energy.
Published Raindrops grow with turbulence in clouds



Tackling a long-time mystery, scientists have found that the turbulent movements of air in clouds play a key role in the growth of water droplets and the initiation of rain. The research can improve computer model simulations of weather and climate and ultimately lead to better forecasts.
Published Parched Central Valley farms depend on Sierras for groundwater



New research shows California's Central Valley, known as America's breadbasket, gets as much as half of its groundwater from the Sierra Nevadas. This is significant for a farming region that, in some parts, relies almost entirely on groundwater for irrigation.
Published Spin qubits go trampolining



Researchers have developed somersaulting spin qubits for universal quantum logic. This achievement may enable efficient control of large semiconductor qubit arrays. The research group recently published their demonstration of hopping spins and somersaulting spins.
Published Seven steps to achieving the right to clean indoor air post-pandemic



Seven lessons learned from the COVID-19 pandemic about ventilation's crucial role in preventing the spread of airborne pathogens has been set out in a new article.
Published Waters along Bar Harbor, Acadia home to billions of microplastics



Researchers reveal there are an estimated 400 billion microplastic fibers on the surface of Frenchman Bay, which borders Bar Harbor and Acadia National Park in Maine, and several connected rivers and estuaries where freshwater from rivers meet salty seawater. The watershed contains an average of 1.8 fibers per liter of water. The team also investigated how microplastics traveled throughout the watershed by sampling water from nine sites on Mount Desert Island, particularly within Bar Harbor.
Published How Saharan dust regulates hurricane rainfall



New research underscores the close relationship between dust plumes transported from the Sahara Desert in Africa, and rainfall from tropical cyclones along the U.S. Gulf Coast and Florida.
Published Researchers record images and data of a shark experiencing a boat strike



Researchers have captured what they believe is the first ever video of a shark or any large marine animal being struck by a boat.
Published Drawing water from dry air



A prototype device harvests drinking water from the atmosphere, even in arid places.
Published Better carbon storage with stacked geology



According to new research subsurface reservoirs that are covered by a collection of hundreds of smaller lids -- collectively called a 'composite confining system' -- may be the better option for keeping carbon trapped for the long term. That's good news for the carbon storage industry. This type of distributed system is common in a range of geological environments.
Published Researchers develop more environmentally friendly and cost-effective method for soil remediation



Chemists have developed a rapid electrothermal mineralization (REM) process, which in seconds can remediate the accumulation of synthetic chemicals that can contaminate soil and the environment.
