Published Machine learning, from you


Many computer systems people interact with on a daily basis require knowledge about certain aspects of the world, or models, to work. These systems have to be trained, often needing to learn to recognize objects from video or image data. This data often contains superfluous content that reduces the accuracy of models. So researchers found a way to incorporate natural hand gestures into the teaching process. This way, users can more easily teach machines about objects, and the machines can also learn more effectively.
Published Mathematicians explain how some fireflies flash in sync


A new study by mathematicians shows that math borrowed from neuroscience can describe how swarms of these unique insects coordinate their light show, capturing key details about how they behave in the wild.
Published A faster experiment to find and study topological materials


Researchers have found an efficient way to identify 'topological' materials, whose surfaces can have different electrical or functional properties than their interiors. The approach should make it easier uncover materials that could be the basis of next-generation computer chips or quantum devices.
Published Rewards only promote cooperation if the other person also learns about them


Researchers show that reputation plays a key role in determining which rewarding policies people adopt. Using game theory, they explain why individuals learn to use rewards to specifically promote good behavior.
Published Unveiling the dimensionality of complex networks through hyperbolic geometry



Reducing redundant information to find simplifying patterns in data sets and complex networks is a scientific challenge in many knowledge fields. Moreover, detecting the dimensionality of the data is still a hard-to-solve problem. A new article presents a method to infer the dimensionality of complex networks through the application of hyperbolic geometrics, which capture the complexity of relational structures of the real world in many diverse domains.
Published Mathematical modeling suggests U.S. counties are still unprepared for COVID spikes



America was unprepared for the magnitude of the pandemic, which overwhelmed many counties and filled some hospitals to capacity. A new study suggests there may have been a mathematical method, of sorts, to the madness of those early COVID days.
Published Music class in sync with higher math scores -- but only at higher-income schools


Music and arts classes are often first on the chopping block when schools face tight budgets and pressure to achieve high scores on standardized tests. But it's precisely those classes that can increase student interest in school and even benefit their math achievement, according to a new study.
Published Research reveals magma activity beneath Mount Edgecumbe


Magma beneath long-dormant Mount Edgecumbe volcano in Southeast Alaska has been moving upward through Earth's crust, according to research the Alaska Volcano Observatory rapidly produced using a new method.
Published Detailing a disastrous autumn day in ancient Italy


The Plinian eruption of Mount Vesuvius around 4,000 years ago -- 2,000 years before the one that buried the Roman city of Pompeii -- left a remarkably intact glimpse into Early Bronze Age village life in the Campania region of Southern Italy. The village offers a rare glimpse into the lives of the people who lived there, and the degree of preservation led the researchers to pinpoint the timing of the eruption, based on archaeobotanical record.
Published Earth's newest secret: How volcanoes really work


It isn't every day that we learn something that fundamentally changes how we understand our world. But for volcanologists across the globe, such a revelation has occurred.
Published Wave created by Tonga volcano eruption reached 90 meters -- nine times taller than 2011 Japan tsunami


New research reveals more about the magnitude of January eruption, as researchers call for better preparedness The eruption of the Hunga Tonga-Hunga Ha'apai volcano in January created an initial wave 90 meters high -- almost the height of the Statue of Liberty (93m). Tsunami expert calls for better warning systems to detect volcanic eruptions, saying systems are '30 years behind' comparable earthquake detection tools.
Published Risk of volcano catastrophe 'a roll of the dice'


While funding is pumped into preventing low-probability scenarios such as asteroid collision, the far more likely threat of a large volcanic eruption is close to ignored -- despite much that could be done to reduce the risks, say researchers.

Published Volcanic super eruptions are millions of years in the making -- followed by swift surge


Researchers have discovered that super-eruptions occur when huge accumulations of magma deep in the Earth's crust, formed over millions of years, move rapidly to the surface disrupting pre-existing rock.
Published Cloud study demystifies impact of aerosols


Aerosol particles in the atmosphere have a bigger impact on cloud cover -- but less effect on cloud brightness -- than previously thought, new research shows.
Published New method can improve explosion detection


Computers can be trained to better detect distant nuclear detonations, chemical blasts and volcano eruptions by learning from artificial explosion signals, according to a new method.
Published Shockwave caused by Tonga underwater eruption may help scientists predict future tsunami


Using data from the eruption of the underwater volcano near Tonga in 2022, researchers used disturbances in Earth's upper atmosphere to track the airwaves that cause tsunami. Their findings may lead to speedier predictions of these giant waves.
Published Fiber optic sensing detects tremor from Icelandic subglacial volcano


Researchers used a fiber optic cable on the ice cap of an Icelandic subglacial volcano to detect low-frequency volcanic tremor, suggesting this technology could be useful in monitoring other ice-covered volcano systems.
Published Volcano's eruption will help scientists plot weather, climate


As it captivated people around the world, the January eruption of the Hunga Tonga-Hunga Ha'apai volcano gave scientists a once-in-a-lifetime chance to study how the atmosphere works, unlocking keys to better predict the weather and changing climate.
Published Tonga volcano eruption among the most powerful ever observed, triggering atmospheric gravity waves that reached the edge of space


The eruption of the Hunga Tonga-Hunga Ha'apai submarine volcano in January 2022 was one of the most explosive volcanic events of the modern era, a new study has confirmed.
