Published Toward a code-breaking quantum computer



Building on a landmark algorithm, researchers propose a way to make a smaller and more noise-tolerant quantum factoring circuit for cryptography.
Published Physicists develop new method to combine conventional internet with the quantum internet



Researchers send entangled photons and laser pulses of the same color over a single optical fiber for the first time.
Published Recent volcanic 'fires' in Iceland triggered by storage and melting in crust



Scientists have detected geochemical signatures of magma pooling and melting beneath the subsurface during the 'Fagradalsfjall Fires', that began on Iceland's Reykjanes peninsula in 2021. Samples show that the start of the eruption began with massive pooling of magma, contrasting initial hypothesis for magma ascent straight from the mantle.
Published Optical fibers fit for the age of quantum computing



A new generation of specialty optical fibers has been developed by physicists to cope with the challenges of data transfer expected to arise in the future age of quantum computing.
Published New study disputes Hunga Tonga volcano's role in 2023-24 global warm-up



New research is exploring the climate impact of the 2022 Hunga Tonga volcano eruption and challenging existing assumptions about its effects in the process.
Published Mass layoffs and data breaches could be connected



A research team has been exploring how mass layoffs and data breaches could be connected. Their theory: since layoffs create conditions where disgruntled employees face added stress or job insecurity, they are more likely to engage in risky behaviors that heighten the company's vulnerability to data breaches.
Published Mechanical computer relies on kirigami cubes, not electronics



Researchers have developed a kirigami-inspired mechanical computer that uses a complex structure of rigid, interconnected polymer cubes to store, retrieve and erase data without relying on electronic components. The system also includes a reversible feature that allows users to control when data editing is permitted and when data should be locked in place.
Published Iceland's volcano eruptions may last decades



Scientists predict from geochemical data that Iceland is entering a new volcanic era that will last for decades, possibly centuries. Under an hour's drive from the country's capital city, the ongoing eruptions pose considerable risks for economic disruption, and they leave evacuated communities uncertain of a possible return.
Published Video analysis of Iceland 2010 eruption could improve volcanic ash forecasts for aviation safety



Video footage of Iceland's 2010 Eyjafjallaj kull eruption is providing researchers with rare, up-close observations of volcanic ash clouds -- information that could help better forecast how far explosive eruptions disperse their hazardous ash particles.
Published Mapping lava flows with groundbreaking field instrument



Researchers develop a tool for measuring the viscosity of lava that could increase our understanding of molten rock as well as better improve models of its movement, giving authorities crucial guidance for keeping people safe. They attached a metal rod to a force gauge for accurate measurements and coupled it with a second rod to measure displacement. The entire instrument is designed to be both lightweight enough to be hand-held and durable enough to hold up in a volcanic environment.
Published Earth scientists describe a new kind of volcanic eruption



By analyzing the dynamics of 12 back-to-back explosions that happened in 2018, researchers describe a new type of volcanic eruption mechanism. The explosions were driven by sudden pressure increases as the ground collapsed, which blasted plumes of rock fragments and hot gas into the air, much like a classic stomp-rocket toy.
Published Highly sensitive fiber optic gyroscope senses rotational ground motion around active volcano



Researchers have built a prototype fiber optic gyroscope for high resolution, real-time monitoring of ground rotations caused by earthquakes in the active volcanic area of Campi Flegrei in Naples, Italy. A better understanding of the seismic activity in this highly populated area could improve risk assessment and might lead to improved early warning systems.
Published Clues from deep magma reservoirs could improve volcanic eruption forecasts



New research into molten rock 20km below the Earth's surface could help save lives by improving the prediction of volcanic activity.
Published VR may pose privacy risks for kids: A new study finds parents aren't as worried as they should be



New research finds that, while an increasing number of minors are using virtual reality (VR) apps, not many parents recognize the extent of the security and privacy risks that are specific to VR technologies. The study also found that few parents are taking active steps to address those security and privacy issues, such as using parental controls built into the apps.
Published Computer scientists unveil novel attacks on cybersecurity



Researchers have found two novel types of attacks that target the conditional branch predictor found in high-end Intel processors, which could be exploited to compromise billions of processors currently in use.
Published This tiny chip can safeguard user data while enabling efficient computing on a smartphone



A new chip can efficiently accelerate machine-learning workloads on edge devices like smartphones while protecting sensitive user data from two common types of attacks -- side-channel attacks and bus-probing attacks.
Published Clear guidelines needed for synthetic data to ensure transparency, accountability and fairness, study says



Clear guidelines should be established for the generation and processing of synthetic data to ensure transparency, accountability and fairness, a new study says.
Published Breakthrough promises secure quantum computing at home



The full power of next-generation quantum computing could soon be harnessed by millions of individuals and companies, thanks to a breakthrough guaranteeing security and privacy. This advance promises to unlock the transformative potential of cloud-based quantum computing.
Published Cloud engineering could be more effective 'painkiller' for global warming than previously thought



Cloud 'engineering' could be more effective for climate cooling than previously thought, because of the increased cloud cover produced, new research shows.
Published Protecting art and passwords with biochemistry



A new molecular test method helps to prove the authenticity of works of art. The new method could also help to make passwords secure against quantum computers.
