Supporters of the large-scale Mississippi River sediment diversions currently being planned by the Louisiana Coastal Protection and Restoration Authority got a boost to their case recently when scientists published an analysis of two existing freshwater diversions on the state's coastline, one of which shows a significant amount of land having formed over the past 17 years.

Satellite observations have revealed that weak seismic ground shaking can trigger powerful landslide acceleration -- even several years after a significant earthquake.

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.

On March 11, 2011, multiple catastrophes in Japan were triggered by the Great East Japan Earthquake, including the nuclear accident at the Fukushima Daiichi Nuclear Power Plant. This event, also known as the 3/11 disaster, is what is known as a compound disaster. Now that over a decade has passed since this event, researchers are investigating how to prevent the next compound disaster.

Subduction zones, where one tectonic plate slides beneath another, produce the most devastating seismic, volcanic, and landslide hazards on the planet. A new report presents an ambitious plan to make major advances in understanding subduction zone hazards by bringing together a diverse community of scientists in a long-term collaborative effort, deploying new instrumentation in subduction zones, and developing more sophisticated and accurate models.

A devastating fire followed by an intense rainstorm triggered mudslides in Southern California in 2018 that claimed 23 lives. New findings elucidate the physics behind the deadly disaster that may inform predictive models of future mudslides.

Rapidly evolving floods are a major and growing hazard worldwide. Currently, their onset and evolution is hard to identify using existing systems. However, seismic sensors already in place to detect earthquakes could be a solution to this problem. Researchers show that a seismometer can sense a flood, such as the devastating one that hit Germany in July 2021, up to 1.5 km away. This could act as an early warning to save lives and lessen damage. They also found that being able to measure the 'seismic footprint' of the flood provides information on its magnitude, velocity and trajectory in real time, which could be used for future flood protection.

Researchers recently published a study looking at land use changes from the past and the importance of taking factors such as socio-economic development and the dynamic nature of coastal environments into consideration to make these areas more resilient to climate change.

A new large-scale analysis of hillslope connectivity at the continental scale was recently published. The study gives new understanding of mechanisms that determine how effectively hillslopes drive floods and landslides, as well as promote the presence of wetlands.

Landslides are inevitable, but landslide disasters are not. With this in mind, the U.S. Geological Survey has released a new report that details the strategic actions necessary to equitably reduce the Nation's risk from landslide hazards.

Computer scientists have succeeded in developing a method for systematically finding the optimal quantum operation sequence for a quantum computer. They have developed a systematic method that applies optimal control theory (GRAPE algorithm) to identify the theoretically optimal sequence from among all conceivable quantum operation sequences. This method is expected to become a useful tool for medium-scale quantum computers and is expected to contribute to improving the performance of quantum computers and reducing environmental impact in the near future.

University of Cincinnati geologists reconstructed a massive landslide in Nevada that wiped out an area the size of a small city more than 5 million years ago. Researchers pieced together details of the Blue Diamond landslide, a natural disaster that sent rocks and boulders tumbling more than 6 miles across what is now a desert outside Las Vegas. The landslide in Red Rock Canyon National Conservation Area had such mass and force that it propelled fragmented rock 2 miles uphill, cresting the enormous Blue Diamond Hill, and flattened an area larger than downtown Cincinnati. Rubble from the landslide stretches over an area of more than 7 square miles.

Scientists have developed a mathematical description of what happens within tiny magnets as they fluctuate between states when an electric current and magnetic field are applied. Their findings could act as the foundation for engineering more advanced computers that can quantify uncertainty while interpreting complex data.

Researchers have shown that a component of modern computer processors that enables different areas of the chip to communicate with each other is susceptible to a side-channel attack. An attacker can monitor how traffic from two different cores on a processor interferes with each other to extract secret information, like a cryptographic key.

With record temperatures this summer along with dry conditions, ongoing concerns about food security, wildlife habitats and biodiversity, having a healthy soil system is more vital and challenging than ever before. But what does the term 'soil health' mean and how should we measure it? New research says that how we think about, measure and study soil must be changed to give a better understanding of how to manage this resource effectively, with academics proposing an entirely new approach for assessing soil health.

The catastrophic debris flow that affected Montecito, Calif., in early January, 2018 was the result of a rare confluence of severe events. The Thomas Fire had been raging for weeks in Ventura and Santa Barbara counties, and an unusually strong winter storm dumped half an inch of rain in five minutes on the newly-charred hills above the suburban enclave. With the tough vegetation that holds the hillsides in place burned off by the fire, tons of water, silt, burnt plant matter and rocks roared down the slopes and engulfed the community below, causing massive damage and the death of 23 residents.

A method known as quantum key distribution has long held the promise of communication security unattainable in conventional cryptography. An international team of scientists has now demonstrated experimentally, for the first time, an approach to quantum key distribution that is based on high-quality quantum entanglement -- offering much broader security guarantees than previous schemes.

An international team has successfully implemented an advanced form of quantum cryptography for the first time. Moreover, encryption is independent of the quantum device used and therefore even more secure against hacking attempts.
