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.

Researchers found a high probability of flood damage -- including monetary damage, human injury and loss of life -- for more than a million square miles of land across the United States across a 14-year period.

The United States is expected to experience as much sea level rise by the year 2050 as it witnessed in the previous hundred years. That's according to a NOAA-led report updating sea level rise decision-support information for the U.S. released in partnership with half a dozen other U.S.federal agencies.

Field surveys conducted in the days after the 7 January 2020 Puerto Rico earthquake documented more than 300 landslides and severe liquefaction in southern coastal regions, according to a new study.

Scientists develop a chaos-based stream cipher that can withstand attacks from large-scale quantum computers.

Climate change could result in the financial toll of flooding rising by more than a quarter in the United States by 2050 -- and disadvantaged communities will bear the biggest brunt, according to new research.

New research looks to improve prediction of brief but intense rainstorms that can cause devastating flash floods and landslides. Intense rain associated with narrow cold-frontal rainbands may last only a few minutes at a particular location, yet the rain can cause catastrophic flash flooding, debris flows and landslides, and can occur along with tornadoes and severe thunderstorms.

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.

The dramatic collapse of Indonesia's Anak Krakatau volcano in December 2018 resulted from long-term destabilising processes, and was not triggered by any distinct changes in the magmatic system that could have been detected by current monitoring techniques, new research has found.

Computer systems that are physically isolated from the outside world (air-gapped) can still be attacked. This is demonstrated by IT security experts. They show that data can be transmitted to light-emitting diodes of regular office devices using a directed laser. With this, attackers can secretly communicate with air-gapped computer systems over distances of several meters. In addition to conventional information and communication technology security, critical IT systems need to be protected optically as well.

A study showed that -- within an appropriate framework -- gait recognition could be a viable technique for protecting individuals and their data from potential crime.

New research examining whether forests can mitigate flood risk suggests they may offer less protection against major events than had been hoped. Although the work, which was carried out in forest sites in Ireland and the UK, showed forests can suppress small storm flows it also underlined that they are likely to make minimal difference in reducing the devastating impacts of major flood events.

Researchers have developed a method for incorporating security in the physical nature of the wireless transmission signal for 5G and future networks.

Understanding how climate change will affect the flooding of rivers may become easier with a new framework for assessing flood risk that's been developed by an interdisciplinary team.

Rising oceans get more attention in climate change discussions, but rivers are rising, too, according to new research. The research shows that rivers need more attention in policy management and disaster preparation, both at the coast and farther inland.

Researchers outline how they were able to establish a clear pattern between the strength of the monsoon season in Nepal and the amount of landsliding over a 30-year period between 1988 and 2018.

Researchers have used a nanoantenna to focus light onto a single semiconductor nanobox. This approach will enhance the utility of quantum repeater technology currently under development for advanced communication and data storage. Such technology is essential to overcoming the limitations of classical computer information for securely sharing information over long distances.

Computer scientists have discovered an inexpensive way for tech companies to implement a rigorous form of personal data privacy when using or sharing large databases for machine learning.

To counter hacking, researchers have developed a new system based on the concept of 'zero-knowledge proofs', the security of which is based on the physical principle of relativity: information cannot travel faster than the speed of light. Thus, one of the fundamental principles of modern physics allows for secure data transfer.

Physicists have described in theoretical terms how to develop codes that cannot be broken by quantum computers -- computing devices of the future. These codes rely on distributing single photons that share a quantum character solely among the parties that wish to communicate.
