The rivers running through the hearts of Australia's major cities and towns are often carrying heavy loads of nutrients and sediments.
Staff in public and private hospitals in Mexico City are likely to follow well-established and reinforced earthquake early warning (EEW) protocols for evacuation, according to an ongoing study.
Beaver ponds contain nitrogen, an essential nutrient that can become a pollutant when too much is present. Land managers need to know if beaver ponds are storing or releasing nitrogen, but chemical testing can be expensive. A new study shows how simple mapping of a beaver pond's depth and sediment can tell managers whether it's a nitrogen source or sink.
Tsunami deposits identified in a coastal mangrove pond in Northwest Puerto Rico could have come from a megathrust earthquake at the Puerto Rico Trench that occurred between 1470 and 1530, according to research reported at the Seismological Society of America (SSA)'s 2023 Annual Meeting.
In recent years, large, intense wildfires, known as megafires, have increasingly caused severe damage to forests, homes, and crops. In addition to megafires fatally impacting humans and wildlife alike, they may also be impacting climate change. New research led by UMBC's Stephen Guimond provides insight into how the large smoke plumes produced by megafires can be more accurately modeled and...
In 1876, when University of Illinois professor Manly Miles established the Morrow Plots, he couldn't have imagined the plots would become the oldest continuous agricultural experiment in the Western Hemisphere. Nor could he imagine, more than a century before the dawn of the internet, that the plots' data would be digitized and made available online to scientists, students, and educators around...

An international team of researchers lays the foundation to examine how extracellular RNA and its carrier proteins found in bodily fluids function in a healthy as well as a diseased setting, potentially providing a means to accurately implement early detection and monitor disease processes.
In autumn 2022 and winter 2023, a total of 20 cheetahs from Namibia and South Africa were introduced to Kuno National Park in India to establish a free-ranging population -- for the first time since their extinction in India 70 years ago. Although the idea may be commendable, getting it right is not so easy. Scientists see shortcomings in the reintroduction plan: In southern Africa, cheetahs live...
A new article shows how the choice of network representation can influence the observed effects. Their work focuses on the phenomenon of synchronization, which emerges in systems from circadian clocks to vascular networks.
Engineers developed a method to create synthetic spider silk at high yields while retaining strength and toughness using mussel foot proteins.
A decade's worth of research at oil and gas operations in the central and eastern United States has confirmed that fluid injection from hydraulic fracturing and wastewater disposal can induce seismicity.
ChatGPT faced off against students on accounting assessments. Students scored an overall average of 76.7%, compared to ChatGPT's score of 47.4%. On a 11.3% of questions, ChatGPT scored higher than the student average, doing particularly well on AIS and auditing. But the AI bot did worse on tax, financial, and managerial assessments, possibly because ChatGPT struggled with the mathematical...
Last month, OpenAI launched its newest AI chatbot product, GPT-4. According to the folks at OpenAI, the bot, which uses machine learning to generate natural language text, passed the bar exam with a score in the 90th percentile, passed 13 of 15 AP exams, and got a nearly perfect score on the GRE Verbal test.
]An international team led by researchers at Baylor College of Medicine with the National Institutes of Health Extracellular RNA Communication Consortium and the Bogdan Mateescu laboratory at the ETH Zürich and University of Zürich has developed a new powerful resource to study extracellular RNA (exRNA), a novel form of cell-to-cell communication.
At least seven deceased California condors from a northern Arizona population were infected with highly pathogenic avian influenza this spring, the Oregon Veterinary Diagnostic Laboratory at Oregon State University has found.
The harm caused to the Northern Hemisphere's peatlands as a result of wildfires could lead to greater quantities of carbon dioxide being released into the atmosphere, a new study involving the University of Plymouth has warned.
Non-classical states of light such as single photons and entangled photons are key ingredients for chips dedicated to quantum computation, quantum sensing, quantum measurement, etc. Fabrication of a traditional chip is hard, but with billions of dollars of specialized equipment (and guys in white bunny suits) it can be done. Fabrication of a quantum chip is even harder. In addition, sources of...
Scientists from Southwest Research Institute (SwRI) led a team in the unique Citizen Continental-America Telescopic Eclipse (CATE) experiment to image the Sun's outer atmosphere, the corona, during a short solar eclipse on the opposite side of the Earth. Using four platforms in the northwest corner of Australia, the team successfully observed the million-degree solar corona at the April 20 eclipse...
Researchers use networks to model the dynamics of coupled systems ranging from food webs to neurological processes. Those models originally focused on pairwise interactions, or behaviors that emerge from interactions between two entities. But in the last few years, network theorists have been asking, what about phenomena that involve three or more? In medicine, antibiotic combinations may fight a...
Scientists have long been intrigued by the remarkable properties of spider silk, which is stronger than steel yet incredibly lightweight and flexible. Now, Fuzhong Zhang, a professor of energy, environmental and chemical engineering at the McKelvey School of Engineering at Washington University in St. Louis, has made a significant breakthrough in the fabrication of synthetic spider silk, paving...
Even if you are not a quantum physicist, you will most likely have heard of Schrödinger's famous cat. Erwin Schrödinger came up with the feline that can be alive and dead at the same time in a thought experiment in 1935. The obvious contradiction—after all, in everyday life we only ever see cats that are either alive or dead—has prompted scientists to try to realize analogous situations in...
Researchers at UT Southwestern Medical Center have discovered how a bacterium that infects people after they eat raw or undercooked shellfish creates syringe-like structures to inject its toxins into intestinal cells. The findings, published in Nature Communications, could lead to new ways to treat food poisoning caused by Vibrio parahaemolyticus.
