Published Rare opportunity to study short-lived volcanic island reveals sulfur-metabolizing microbes


On the short-lived island of Hunga Tonga Hunga Ha'apai, researchers discovered a unique microbial community that metabolizes sulfur and atmospheric gases, similar to organisms found in deep sea vents or hot springs.
Published Predicting lava flow


A team is collecting data that will be used to create models that can help improve lava flow forecasting tools that are useful in determining how hazards impact populations. One such tool, known as MOLASSES, is a simulation engine that forecasts inundation areas of lava flow.
Published Using drones to monitor volcanoes: Researchers analyze volcanic gases with the help of ultra-lightweight sensor systems


The main gases released by volcanoes are water vapor, carbon dioxide, and sulfur dioxide. Analyzing these gases is one of the best ways of obtaining information on volcanic systems and the magmatic processes that are underway. The ratio of carbon dioxide levels to those of sulfur dioxide can even reveal the likelihood of an impending eruption. Drones are employed to carry the necessary analytical systems to the site of activity.
Published Signals from the ionosphere could improve tsunami forecasts


The powerful volcanic eruption in January 2022 created ripple effects throughout the world's atmosphere and oceans. Analysis of the Hunga Tonga eruption shows how signals from the ionosphere could help monitor future volcanoes and tsunamis.
Published Purchasing loot boxes in video games associated with problem gambling risk, says study


Gamers who buy 'loot boxes' are up to two times more likely to gamble, shows new research.
Published Online gaming enhances career prospects and develops soft skills, finds new study


Online gaming behavior can encourage gamers to gain a variety of soft skills which could assist them with training to support their career aspirations, according to new research.
Published Microlaser chip adds new dimensions to quantum communication


With only two levels of superposition, the qubits used in today's quantum communication technologies have limited storage space and low tolerance for interference. Engineering's hyperdimensional microlaser generates 'qudits,' photons with four simultaneous levels of information. The increase in dimension makes for robust quantum communication technology better suited for real-world applications.
Published Monitoring 'frothy' magma gases could help evade disaster


Volcanic eruptions are dangerous and difficult to predict. A team has found that the ratio of atoms in specific gases released from volcanic fumaroles (gaps in the Earth's surface) can provide an indicator of what is happening to the magma deep below -- similar to taking a blood test to check your health. This can indicate when things might be 'heating up.' Specifically, changes in the ratio of argon-40 and helium-3 can indicate how frothy the magma is, which signals the risk of different types of eruption. Understanding which ratios of which gases indicate a certain type of magma activity is a big step. Next, the team hopes to develop portable equipment which can provide on-site, real-time measurements for a 24/7 volcanic activity monitoring and early warning system.
Published Tonga volcano had highest plume ever recorded


Using images captured by satellites, researchers have confirmed that the January 2022 eruption of the Hunga Tonga-Hunga Ha'apai volcano produced the highest-ever recorded plume. The colossal eruption is also the first to have been directly observed to have broken through to the mesosphere layer of the atmosphere.
Published Volcanic activity and low ocean oxygen events linked to climate warming and rapid ice melt during last ice age, study finds


A chemical analysis of sediment cores from the North Pacific Ocean show a consistent pairing of volcanic ash and hypoxia, a low ocean oxygen interval spanning thousands of years, during times of rapid climate warming at the end of the last ice age, new research shows.
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 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 Electronic gaming can trigger potentially lethal heart rhythm problems in susceptible children


Electronic gaming can precipitate life-threatening cardiac arrhythmias in susceptible children whose predisposition may have been previously unrecognized, according to a new report. The investigators documented an uncommon, but distinct pattern among children who lose consciousness while playing electronic (video) games.
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 As few as 1 in 5 COVID cases may have been counted worldwide, mathematical models suggest


Mathematical models indicate that as few as one in five cases of COVID-19 which occurred during the first 29 months of the pandemic are accounted for in the half billion cases officially reported.
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 Gamers can have their cake and eat it too


New research from Japan shows that multiple cognitive abilities may be empirically measured from a complex game experience depending on the game's design.
Published The way you talk to your child about math matters


'You're so smart!' -- This encouraging response may actually do more harm than good to children's math performance, according to a new study. The study found that encouraging children with responses related to their personal traits or innate abilities may dampen their math motivation and achievement over time.
Published Reasons behind gamer rage in children are complex -- and children are good at naming them


Children's outbursts of rage while playing digital games are causing both concern and public debate around the topic. Taking a novel approach to gamer rage, a new study examines the topic from a child's perspective, finding complex reasons for gamer rage in children.
