Clostridium botulinum bacteria produce a potent neurotoxin called botulinum toxin, which causes the serious illness botulism. The toxin attacks the nervous system, leaving the body unable to control its muscles and making every breath a struggle. Without immediate treatment, botu
Researchers at Keele University have discovered that migratory butterflies may use different navigation systems to find their way during migrations, highlighting the importance of understanding how different species may respond to environmental changes.
Vultures were long thought to make few and fairly simple sounds. Yet no one had investigated in detail how the birds use sound to communicate. For his master's thesis in Jorg Massen's Vulture Cognition Lab, Connor Proudfoot studied the critically endangered Rüppell's vulture. He
More than 1 in 4 Detroiters cannot easily produce up-to-date documentation of their U.S. citizenship that matches their current name, according to a new survey from the University of Michigan's Detroit Metro Area Communities Study, in partnership with Outlier Media.
The trauma of war has long-lasting reverberations, influencing business decisions made decades later, argue Eun Hye Jo and Jenny Jung-Wha Lee, accounting professors at Costello College of Business based at George Mason University Korea.
Many structures in biology are bounded by membranes, but not all of them. Droplets of a liquid called a coacervate, which form when oppositely charged molecules come together in water, have attracted attention as models for membraneless compartments inside cells and for "protocel
Marine heat waves are usually seen as destructive events that can disrupt entire ocean ecosystems and trigger massive environmental damage. In 2018 and 2019, an extreme heat wave hit the Bering Sea, causing spring sea ice levels to plummet.
Scientists have cracked a 178-year-old mystery surrounding a train delayed by a solar storm, revealing that the famous incident happened in 1848 rather than 1841. The discovery rewrites the early history of space weather and highlights a threat that still endangers modern power g
Rising temperatures caused by climate change are making it harder to organize outdoor sports events safely. Exercising in the heat lowers performance and raises the risk of heatstroke, which is a leading cause of nontraumatic death among professional athletes.
Your phone vibrates, a notification pops up, or you just take a quick glance at the screen. Even minor interruptions can affect your concentration—not least when you're in class. Now, a large randomized trial involving more than 16,000 students in India shows that teaching withou
Graduate students in Penn State's College of Agricultural Sciences contributed to the first complete genome sequence of a harmful plant pathogen from an ornamental Prunus host through an active-learning activity in a plant disease diagnosis course.
Scientists have learned a lot about what happens to the human body as we age. But there's still much to learn about how other species age, including dogs. Even carrying extra weight could affect a dog's cognitive health. Alexandra Genualdi, a student at Oklahoma State University
Small fish such as sardinella are an affordable source of protein and essential nutrients for millions of people across West Africa.
About 20,000 years ago, an enormous, floating ice shelf more than a mile (1.6 kilometers) thick helped lock in three of the largest ice sheets in northern Canada and Greenland. When that ice shelf disappeared, it helped unlock part of these ice sheets, which contributed to hundre
A new study from Indiana University shows that being in a positive mood leads orangutans to value what they learned more strongly. The study comes from the lab of Erica Cartmill, professor of animal behavior, anthropology and cognitive science in the College of Arts and Sciences
California's coastal bluffs and beaches look rugged, but they can be surprisingly fragile in the face of a powerful El Niño.
Whenever I drive amid the mazelike bustle of Tokyo's Shuto Expressway, where approximately 1 million vehicles transit daily, I see billboard advertisements for all manner of businesses: dentists, hotels, car and tire companies, and affordable funerals. Lots and lots of funerals.
Salt marsh sediment and vegetation can remain largely intact even during extreme storm surges. This was demonstrated in a large-scale experiment in which researchers transported sections of salt marsh to an experimental facility capable of producing the world's largest artificial
Researchers at Eötvös Loránd University (ELTE) have reconstructed approximately 16,000 years of summer temperature changes from sediments collected at Lake Prokoško in Bosnia and Herzegovina. The findings show how the Western Balkans responded to rapid climate changes at the end
New active ingredients for drugs to treat infections, cancer or other serious diseases are often based on substances originally discovered in microorganisms, plants or other living organisms. Producing or improving such active ingredients in a targeted manner using microorganisms
Imagine you have a bag you really like. It felt like "the one" when you bought it. Over time, it starts to look worn. There are some scuffs on it. Nothing is actually wrong with the bag, and it still works exactly as it should. Yet, once you notice those imperfections, you start
What causes adversaries to escalate conflicts into costly, prolonged wars even when neither side wants to fight? And in the fog of war, what might help them break that cycle and find a path to peace?
Imagine planning a vacation across India's Golden Triangle: Delhi, Agra and Jaipur. You could compare dozens of websites, scroll through reviews and ask friends for recommendations.
