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 New Zealand's flightless birds are retreating to moa refuges



Researchers have found New Zealand's endangered flightless birds are seeking refuge in the locations where six species of moa last lived before going extinct.
Published Exploring consciousness with eureka moments



We all know what it's like when the penny suddenly drops. Animals too experience such moments of insight. They could prove useful for research of consciousness.
Published Rock art and archaeological record reveal humans' complex relationship with Amazonian animals



Rock art explored by archaeologists in the Colombian Amazon has provided an insight into the complex relationship between the earliest settlers on the continent and the animals they encountered.
Published Size doesn't matter for mammals with more complex brains



Mammals that have evolved more developed brains tend to have a smaller size difference between males and females of that species, according to new research.
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 How evolution tamed a deadly virus and why we should still worry



Over the last century, a once-deadly mosquito-borne virus has evolved so that it no longer sickens humans. New research shows that changes in the virus's ability to target human cells paralleled the decline in illness and death. The findings offer important lessons in virology that may help guide better preparedness for future outbreaks of other viral diseases.
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 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 Hens blush when they are scared or excited, study finds



Hens fluff their head feathers and blush to express different emotions and levels of excitement, according to a new study.
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 Proof-of-concept study to find functional cure for HIV



Researchers conducted a breakthrough proof-of-concept study that found an HIV-like virus particle that could cease the need for lifelong medications.
Published See less to move better: Dynamic schooling of fish by visual selection and focus



Sometimes less is more. Researchers accurately modeled dynamic fish schooling by incorporating the tendency of fish to focus on a single visual target instead of the whole school, as well as other visual cues.
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.
