Published New research could provide earlier warning of tsunamis
(via sciencedaily.com) A new method of detecting mega earthquakes, which picks up on the gravity waves they generate by using deep-learning models, can estimate earthquake magnitude in real time and provide earlier warning of tsunamis.
Published Lake Erie quakes triggered by shifting water levels? Study finds no smoking gun, urges further research
(via sciencedaily.com) In June 2019, a magnitude 4.0 earthquake occurred beneath Lake Erie just off the shoreline of Ohio, about 20 miles northeast of Cleveland.
Published Self-propelled, endlessly programmable artificial cilia
(via sciencedaily.com) Researchers have developed a single-material, single-stimuli microstructure that can outmaneuver even living cilia. These programmable, micron-scale structures could be used for a range of applications, including soft robotics, biocompatible medical devices, and even dynamic information encryption.
Published Major 2020 Alaska quake triggered neighboring 2021 temblor
(via sciencedaily.com) A study of two powerful earthquakes in adjacent areas off the Alaska Peninsula in 2020 and 2021 shows a connection between the two. It also suggests they may be a part of an 80-year rupture cascade along the fault.
Published Scientific advance leads to a new tool in the fight against hackers
(via sciencedaily.com) A new form of security identification could soon see the light of day and help us protect our data from hackers and cybercriminals. Quantum mathematicians have solved a mathematical riddle that allows for a person's geographical location to be used as a personal ID that is secure against even the most advanced cyber attacks.
Published Space-based system using GPS satellites could warn of incoming tsunamis
(via sciencedaily.com) A new method for detecting tsunamis using existing GPS satellites orbiting Earth could serve as an effective warning system for countries worldwide, according to a new study.
Published Volcanoes at fault if the Earth slips
(via sciencedaily.com) A new study has attributed the root cause of the 2016 Kumamoto earthquakes to specific geological damage. A relatively large dip-slip displacement was discovered at the site. The Futagawa strike-slip fault is a vertical break in the ground tracing a line southwest originating from Mount Aso.
Published Earliest geochemical evidence of plate tectonics found in 3.8-billion-year-old crystal
(via sciencedaily.com) Original source Plate tectonics may be unique to Earth and may be an essential characteristic of habitable planets. Estimates for its onset range from over 4 billion years ago to just 800 million years ago. A new study reports evidence of a transition in multiple locations around the world, 3.8-3.6 billion years ago, from stable 'protocrust' to pressures and processes that look a lot like modern subduction, suggesting a time when plates first got moving.
Published Neural network model helps predict site-specific impacts of earthquakes
(via sciencedaily.com) Original source In disaster mitigation planning for future large earthquakes, seismic ground motion predictions are a crucial part of early warning systems. The way the ground moves depends on how the soil layers amplify the seismic waves (described in a mathematical site 'amplification factor'). However, geophysical explorations to understand soil conditions are costly, limiting characterization of site amplification factors to date. Using data on microtremors in Japan, a neural network model can estimate site-specific responses to earthquakes based on subsurface soil conditions.
Published A swarm of 85,000 earthquakes at the Antarctic Orca submarine volcano
(via sciencedaily.com) In a remote area, a mix of geophysical methods identifies magma transfer below the seafloor as the cause.
Published New technique offers faster security for non-volatile memory tech
(via sciencedaily.com) Researchers have developed a technique that leverages hardware and software to improve file system security for next-generation memory technologies called non-volatile memories (NVMs). The new encryption technique also permits faster performance than existing software security technologies.
Published Technology has the potential to change the patient-provider relationship
(via sciencedaily.com) As personal health records (AKA patient portals) allowing patients to see test results, medications and other health information gain in popularity, scientists studied cancer patients' and doctors' differing perceptions of this tool. Patients cited potential for personal health records to deepen their relationship with their healthcare provider and to allow them to be more understood. Physicians were interested in having more clinical information sharing to facilitate better patient care.
Published Single-photon source paves the way for practical quantum encryption
(via sciencedaily.com) Researchers describe new high-purity single-photon source that can operate at room temperature. The source is an important step toward practical applications of quantum technology, such as highly secure communication based on quantum key distribution (QKD).
Published Tiny, cheap solution for quantum-secure encryption
(via sciencedaily.com) Engineers propose a new kind of encryption to protect data in the age of quantum computers.
Published Qubits: Developing long-distance quantum telecommunications networks
(via sciencedaily.com) Computers, smartphones, GPS: quantum physics has enabled many technological advances. It is now opening up new fields of research in cryptography (the art of coding messages) with the aim of developing ultra-secure telecommunications networks. There is one obstacle, however: after a few hundred kilometers within an optical fiber, the photons that carry the qubits or 'quantum bits' (the information) disappear. They therefore need 'repeaters', a kind of 'relay', which are partly based on a quantum memory. By managing to store a qubit in a crystal (a 'memory') for 20 milliseconds, a team has now taken a major step towards the development of long-distance quantum telecommunications networks.
Published Tiny magnets could hold the secret to new quantum computers
(via sciencedaily.com) Scientists have discovered a type of magnetic behavior that could help enable magnetically based quantum devices.
Published Double locked: Polymer hydrogels secure confidential information
(via sciencedaily.com) The development of highly secure but simple and inexpensive encryption technology for the prevention of data leaks and forgeries is decidedly challenging. A research team has now introduced a 'double lock' based on thermoresponsive polymer hydrogels that encrypts information so that it can only be read at a specific window in temperature and time.
Published A security technique to fool would-be cyber attackers
(via sciencedaily.com) Researchers developed a technique that effectively protects computer programs' secret information from memory-timing side channel attacks, while enabling faster computation than other security schemes.
Published The power of chaos: A robust and low-cost cryptosystem for the post-quantum era
(via sciencedaily.com) Scientists develop a chaos-based stream cipher that can withstand attacks from large-scale quantum computers.
Published How big does your quantum computer need to be?
(via sciencedaily.com) Researchers decided to explore two very different quantum problems: breaking the encryption of Bitcoin and simulating the molecule responsible for biological nitrogen fixation. They describe a tool they created to determine how big a quantum computer needs to be to solve problems like these and how long it will take.
