Sensors that detect changes in atmospheric pressure due to ground shaking can also obtain data about large earthquakes and explosions that exceed the upper limit of many seismometers, according to new research.

Pharmaceutical drugs can save lives, but taking these medications as prescribed—especially among those with chronic conditions—can be challenging, for a variety of different reasons. Improving medication adherence could reduce unfavorable health outcomes, hospitalizations, and preventable deaths, while simultaneously reducing health care costs by up to $300B annually in the United States...
The Mastcam-Z instrument aboard NASA's Perseverance Mars rover recently collected 152 images while looking deep into Belva Crater, a large impact crater within the far larger Jezero Crater. Stitched into a dramatic mosaic, the results are not only eye-catching, but also provide the rover's science team some deep insights into the interior of Jezero.
To help learners of all ages understand how to safely observe the Oct. 14, 2023, annular solar eclipse and the April 8, 2024, total solar eclipse, NASA has released a new set of resources for educators.
Produce such as lettuce and spinach is routinely tested for foodborne pathogenic bacteria like salmonella, listeria monocytogenes and pathogenic types of E. coli in an effort to protect consumers from getting sick.
For the first time, a newly published artificial intelligence (AI) algorithm is allowing researchers to quickly and accurately estimate coastal fish stocks without ever entering the water. This breakthrough could save millions of dollars in annual research and monitoring costs while bringing data access to least-developed countries about the sustainability of their fish stocks.
Scientists are often trained to seek out the absolute best solution to a given problem. On a chalk board, this might look something like drawing a graph to find a function's minimum or maximum point. When designing a turbojet engine, it might mean tweaking the rotor blades' angles a tiny degree to achieve a tenth of a percent increase in efficiency.
Since Michigan is the nation's leading producer of tart cherries, Michigan State University researchers were searching for the genes associated with tart cherry trees that bloom later in the season to meet the needs of a changing climate. They started by comparing DNA sequences from late-blooming tart cherry trees to the sequenced genome of a related species, the peach. However, in a surprise to...
Researchers of the HSE Centre for Language and Brain have investigated the impact of both auditory and visual noise on semantic processing during reading to determine if it results in a more superficial reading style that emphasizes the meanings of individual words over connections between them in a sentence.
When individuals share videos about surprise reunions with their intimate partners on the internet, the reaction from viewers may not be the roses and unicorns the posters expected. Viewers' responses to shared videos have the potential to shape offline relationships, a case study of one such video found.
Across the United States over the past decade, an average of over 61,000 wildfires have burned some 7.2 million acres per year. Once a wildfire starts spreading, the firefighting task is exacerbated by issues like spot fires, where winds carry lofted sparks and start new fires outside of the original fire perimeter. The greater the potential spot fire distance, the more difficult wildfires are to...
Reading about climate-induced immigration prompted negative, nativist attitudes among people toward the affected migrants—an unintended, perhaps even paradoxical effect of many delivering the original messages, according to researchers at the University of Michigan and elsewhere.
Globally, critical thinking (CT) is regarded as a highly desirable cognitive skill that enables a person to question, analyze, and assess an idea or theory from multiple perspectives. CT has become an integral and mandatory part of global educational curricula, but its definition varies across contexts and cultural backgrounds.
For more than 10 years, Guoliang Huang, the Huber and Helen Croft Chair in Engineering at the University of Missouri, has been investigating the unconventional properties of "metamaterials"—an artificial material that exhibits properties not commonly found in nature as defined by Newton's laws of motion—in his long-term pursuit of designing an ideal metamaterial.
Climbing caribou numbers in northeastern British Columbia prove that collaborations between Indigenous and colonial governments can reverse decades-long declines, but focus needs to shift to culturally meaningful recovery targets, a consortium of researchers and community members say in a new paper published this week in Science.
The tiny visual systems of flying insects have inspired researchers of the Hong Kong Polytechnic University (PolyU) to develop optoelectronic graded neurons for perceiving dynamic motion, enriching the functions of vision sensors for agile response.
When most people think of crystals, they picture suncatchers that act as rainbow prisms or the semi-transparent stones that some believe hold healing powers. However, to scientists and engineers, crystals are a form of materials in which their constituents—atoms, molecules, or nanoparticles—are arranged regularly in space. In other words, crystals are defined by the regular arrangement of...
High power/energy ultrafast fiber lasers have broadband applications in material processing, medicine, advanced manufacturing and other fields. Compared with solid-state lasers, fiber lasers have the advantages of compact systems, flexibility, good heat dissipation and high beam quality.
Every second, the planet loses a stretch of forest equivalent to a football field due to logging, fires, insect infestation, disease, wind, drought, and other factors. In a recently published study, researchers from the U.S. Geological Survey Earth Resources Observation and Science (EROS) Center presented a comprehensive strategy to detect when and where forest disturbance happens at a large scale...
Zachary Zhong had heard his grandparents' stories about the Japanese invasion in 1944 of neighboring counties in his hometown in China. As the Japanese army continued their advance, civilians were killed and injured, while others fled the invaders' path, some taking shelter in his family's ancestral home.
With Colorado's snowpack ranging from ample to exceptional this spring, hikers who adore wildflowers may already be envisioning days of strolling along lush landscapes of spectacular blooms under columbine-blue skies when all that snow melts.
Joan Palumbo wasn't told the danger she was in when she stepped under the showerhead in her bathroom in Jacksonville, North Carolina.
After years of pioneering work, researchers at the Department of Energy's SLAC National Accelerator Laboratory have completed the detector towers that will soon sit at the heart of the SuperCDMS SNOLAB dark matter detection experiment.
Researchers have reported a strategy to disentangle the activity-selectivity tradeoff for direct conversion of syngas, a mixture of carbon monoxide and hydrogen, into desirable ethylene, propylene, and butylene. These hydrocarbons are known as light olefins and are the most-used building blocks for plastics.
Since their protection under the Endangered Species Act, wolf populations have been making a comeback in the continental United States. Conservationists have argued that the presence of wolves and other apex predators, so named because they have no known predators aside from people, can help keep smaller predator species in check.
