A study by scientists at NTU Singapore has found that implementing robust air pollution control measures could mean Southeast Asian countries prevent as many as 36,000 ozone-related premature deaths each year by 2050.
A research team has developed a unified theoretical framework to better predict the performance of single-atom catalysts (SACs) for electrochemical carbon dioxide reduction (CO₂RR). Their model incorporates both pH and interfacial electric field effects—two critical factors that have often been overlooked or oversimplified in conventional catalyst studies.
In a first, researchers from NASA and Virginia Tech have used satellite data to measure the height and speed of potentially hazardous flood waves traveling down U.S. rivers. The three waves they tracked were likely caused by extreme rainfall and by a loosened ice jam.
Lake Tahoe is experiencing large-scale shifts in ultraviolet radiation (UV) as climate change intensifies wet and dry extremes in the region. That is according to a study led by the University of California, Davis's Tahoe Environmental Research Center and co-leading collaborator Miami University in Ohio.
Archaeologist Greer Jarrett at Lund University in Sweden has been sailing in the footsteps of Vikings for three years. He can now show that the Vikings sailed farther away from Scandinavia and took routes farther from land than was previously believed to have been possible. In his latest study, he has found evidence of a decentralized network of ports, located on islands and peninsulas, which probably played a central role in trade and travel in the Viking era.
The Los Angeles region has some of the most polluted air in the United States, failing to meet standards set by the Environmental Protection Agency for the last decade. Now, Caltech researchers have quantified the levels of a component of smog called ammonium nitrate, a molecule that has been notoriously difficult to measure, and have found that there is much more of it than previously calculated, especially on the most polluted days.
Members of the space exploration community are always coming up with novel ideas to solve problems that they view as holding back humanity's expansion into the cosmos. One such problem that has become more noticeable of late, due to the failure of several powered lunar landers, is the difficulty of landing on the moon.
All of the world's wine-growing regions have been impacted by climate change, but with unequal impacts that vary across the growing season, reports a new study by E.M. Wolkovich of the University of British Columbia and colleagues, published in the journal PLOS Climate.
The benefits of positive expressive writing for psychological health and well-being depend on the particular approach and on individual differences, according to a systematic review published in the journal PLOS One by Lauren Hoult from Northumbria University, U.K., and colleagues.
A serendipitous observation in a Chemical Engineering lab at Penn Engineering has led to a surprising discovery: a new class of nanostructured materials that can pull water from the air, collect it in pores and release it onto surfaces without the need for any external energy.
New research from the Sainsbury Laboratory at the University of Cambridge has shed light on how plants precisely control their growth and development, revealing that seemingly similar molecular components fulfill surprisingly different jobs.
As the number of space travelers is increasing through commercial missions, it becomes more important to understand how space affects the human body.
The global fight against infectious diseases faces two major challenges: the threat of new pandemic outbreaks and the alarming rise of antimicrobial resistance driven by the excessive use of antibiotics. As pathogens continue to evolve and spread, researchers are urgently seeking innovative technologies that can effectively combat viruses, bacteria, and fungi conveniently in everyday settings.
Infamous for their environmental persistence and potential links to health conditions, per- and polyfluoroalkyl substances (PFAS), often called forever chemicals, are being discovered in unexpected places, including beer.
Coastal communities and marine wildlife could benefit from improved monitoring of nutrient pollution in UK waters, according to new research involving scientists at the University of Plymouth.
Laser frequency combs are light sources that produce evenly spaced, sharp lines across the spectrum, resembling the teeth of a comb. They serve as precise rulers for measuring time and frequency, and have become essential tools in applications such as lidar, high-speed optical communications, and space navigation. Traditional frequency combs rely on large, lab-based lasers. However, recent advancements have led to the development of chip-scale soliton microcombs, which generate ultrashort pulses of light within microresonators.
How do insects perceive mechanical stress? This is a question of interest in many different fields, including comparative morphology, neurobiology and robotics.
Gully erosion is the most severe form of soil erosion, and it can seriously impact agricultural fields, contributing to sediment loss and severe nutrient runoff into waterways. Gullies can be triggered suddenly by a single heavy rainfall event, creating deep channels that are difficult to rehabilitate even with heavy machinery. Accurately predicting where gully erosion is likely to occur allows agricultural producers and land managers to target their conservation efforts more effectively.
In nature, ecosystems are tightly linked through the flow of organisms, detritus, and nutrients across boundaries arbitrarily imagined by humans. These systems are deeply in tune with seasonal changes, fostering a harmonious ebb and flow of resources.
As a strictly protected species, sand lizards are dependent on the preservation of their habitats—especially in view of declining populations in Germany. Sand lizards sometimes find ideal living conditions along railway lines—as a new study published in the journal Salamandra by the Museum für Naturkunde Berlin shows.
Hurricane winds are a major contributor to storm-related losses for people living in the southeastern coastal states. As the global temperature continues to rise, scientists predict that hurricanes will get more destructive—packing higher winds and torrential rainfall. A new study, published in the journal Risk Analysis, projects that wind losses for homeowners in the Southeastern coastal states could be 76% higher by the year 2060 and 102% higher by 2100.
A new study published in Science Advances by researchers from the Guangzhou Institute of Geochemistry of the Chinese Academy of Sciences (GIG-CAS), along with international collaborators, reveals that deeply subducted carbonates can cause significant variations in the redox states of Earth's mantle. This process influences the formation of sublithospheric diamonds and plays a role in the long-term evolution of cratons—ancient stable parts of the continental lithosphere.
The fundamental building blocks for planet formation can exist even in environments with extreme ultraviolet radiation, according to a new study by an international collaboration led by Penn State astronomers.
How do organisms adapt to climate change? A new study reveals the complex interplay between genetic diversity and temperature tolerance evolution.
A new study by Danish researchers has demonstrated that it is possible to develop a consortium of bacteria that can inhibit bacterial pathogens in aquaculture. This could potentially reduce the use of antibiotics in aquaculture and possibly other applications. The study was published in Microbiology Spectrum.
