Across Appalachia and the Rust Belt region, including throughout the city of Pittsburgh, former industrial sites are being transformed into new neighborhoods, research centers and technology hubs.
The malaria parasite is able to detect changes in its host's environment and respond by increasing the production of sexual forms capable of being transmitted to mosquitoes. A study led by the Barcelona Institute for Global Health (ISGlobal) identifies the molecular mechanism underlying this process. The findings, published in Nature Microbiology, answer what has been one of the major unanswered questions in malaria research for decades.
Across South Africa, natural springs are more than sources of freshwater. Some are places of healing, spiritual cleansing and rituals, where communities collect water and maintain longstanding cultural connections with the environment. For example, during cleansing rituals, people bathe in or collect spring water as a way of seeking spiritual renewal, healing and protection. These are known as sacred springs.
The first storm warning for the Miami area wasn't issued until only a few hours before the powerful cyclone made landfall just south of downtown, leaving residents with little time to prepare for what would become the hurricane of their nightmares.
The electronic properties of materials are typically determined by their structure under normal, undisturbed conditions, when they are in a state known as equilibrium. Intense light beams, however, can temporarily reshape a material's electronic band structure (i.e., the range of energy states available to electrons), potentially giving rise to new electronic behaviors.
Cells rely on complex signaling networks in which different molecular pathways communicate with one another. Small GTPases act as molecular switches in these networks, controlling diverse cellular processes such as intracellular transport and cell morphogenesis. Although crosstalk between different families of small GTPases is established in animal cells, whether and how such crosstalk occurs in plants has remained largely unknown.
Stretching more than 200,000 square kilometers (77,000 square miles) across southern Australia, the vast, flat plains of the Nullarbor mark one of the world's largest regions of limestone. It formed when an ancient shallow sea retreated some 14 million years ago.
Ice sheets are fundamental components of the Earth system. Antarctica and Greenland, the two ice sheets currently on Earth, don't just affect their own regions: What happens on these vast masses of land ice influences weather, climate, society and the environment around the planet.
Researchers at the Department of Energy's (DOE) Oak Ridge National Laboratory (ORNL) have released LandScan Mosaic, a next-generation global population distribution dataset that estimates where people are by modeling how buildings are used and occupied throughout the day. Built on the foundation of ORNL's widely used LandScan Global, one of the world's most accurate population distribution datasets, Mosaic's enhancements will improve disaster response, humanitarian assistance, infrastructure planning and national security missions worldwide.
The fight against climate change has a new, spiral-tusked ally: the narwhal.
A previously unknown cat species has been identified in plain sight: at a wildlife sanctuary in Bolivia, where the small, spotted feline had been living for years.
Denny Glover was hoping for a big catch when he went fishing with buddies on the Sacramento River, but he wasn't expecting a fully grown humpback whale.
For decades, an idea has grown in paleontology that, long before scientists began digging up and reconstructing dinosaur bones, the Indigenous San and Basotho in southern Africa noticed them too, incorporating them into songs, myths and immortalizing them on cave walls. But under closer scrutiny, these claims begin to crumble.
This programmable DNA computer can perform arithmetic without the continuous energy input needed by other systems.
When you were in school, what stressed you out the most? For many students, classroom assessments—graded tests, quizzes, group work, presentations, labs and the like—would be near the top of the list.
For nearly two decades, biologist Lauren Deaner has worked with Florida scrub-jays, contributing to population recovery efforts and translocations. Now, as a doctoral researcher in UCF's integrative biology program, she is using that field experience to investigate how genetics, behavior and population dynamics influence the long-term recovery of imperiled species.
New research suggests that a perplexing signal created by a pair of colliding black holes may have been warped by a space-time phenomenon known as gravitational lensing. This theory could finally explain the "impossible" size of the merging singularities, but it also poses a new problem.
Scientists map the hidden protein network that helps red blood cells adapt to oxygen
A study initiated by Dr. Dan Theodorescu, a physician-scientist at the University of Arizona Cancer Center, revealed that the loss of the Y chromosome in men's body tissue could pave the way for cancer to develop. According to research recently published in JCI Insights, the loss of the chromosome, which is common in men as they age, creates a preneoplastic field effect, a hidden zone of genetic vulnerability in normal tissue that provides fertile ground for cancer to develop.
Many of the moons orbiting Saturn, Uranus and Neptune likely conceal oceans of liquid water beneath miles of icy shell. Because life as we know it needs water, these buried oceans rank among the most promising places to search for life beyond Earth.
Across the country, kids are settling into new school-year routines. Parents buy backpacks, teachers arrange desks and lesson plans, and friends reconnect. But in recent years, empty chairs are becoming a more common sight—especially in classrooms where students are already facing the most adversity.
The human brain uses about the same amount of wattage as a lightbulb
Climate models are numerical models used to project future climate change. They simulate the climate from the present into the future by calculating changes in the atmosphere, ocean and other components of the climate system. However, simulations of the present-day climate do not perfectly reproduce observations and contain various biases. The model characteristics that cause these biases can also affect simulations of the future climate. Understanding the causes and impacts of present-day climate biases is therefore important for improving the reliability of future climate projections.
Some children have blond hair that darkens as they grow up. What causes this change?
The Korea Institute of Civil Engineering and Building Technology (KICT) announced that it will apply its early detection technology for quasi-stationary linear rainbands and sudden localized torrential rainfall to the Urban Flood Forecasting Platform operated by the Han River Flood Control Office in Korea for urban flood forecasting.
Before murdering Molly Ticehurst in April 2024, court documents show Daniel Billings had threatened to exploit the limits of policing in her country town: "I will come in the middle of the night … The police won't stop me. I will get to you quicker than they will."
Sexual harassment between peers begins as early as Grade 4 and continues throughout lower secondary school. Most of those who sexually harass others have also experienced harassment themselves. These are among the findings of a doctoral thesis in psychology by Aziz-Kaan Dönmez from the University of Gothenburg, who studied peer sexual harassment among Swedish children and adolescents in Grades 4–9. Dönmez will defend his thesis on October 2.
