• Local Focus Can Prevent Failures in Large Networks

    We live in an increasingly connected world, a fact underscored by the swift spread of the coronavirus around the globe. Underlying this connectivity are complex networks — global air transportation, the internet, power grids, financial systems and ecological networks, to name just a few. The need to ensure the proper functioning of these systems also is increasing, but control is difficult.

  • Climate Change, Land-Use Changes Increase Likelihood of Flood Events

    The German government estimates the total losses resulting from the disastrous floods in July 2021 at 32 billion euros. To improve future preparedness for such extreme events, researchers advise that risk assessments take greater account of the landscape and river courses, how they change, and how sediments are transported. In addition, projections show an increase in the spatial extent and frequency of such extreme events, as well as higher amounts of precipitation.

  • How Not to Solve the Climate Change Problem

    When politicians talk about reaching “net zero” emissions, they’re often counting on trees or technology that can pull carbon dioxide out of the air. What they don’t mention is just how much these proposals or geoengineering would cost to allow the world to continue burning fossil fuels. I’ve been working on climate change for over four decades. Let’s take a minute to come to grips with some of the rhetoric around climate change and clear the air, so to speak.

  • Strengthening U.S. Government’s Enhanced Potential Pandemic Pathogen Framework, Dual Use Research

    Group of scientists, public health experts, policy researchers propose strengthening of U.S. government’s policies regarding enhanced potential pandemic pathogen framework and dual use research of concern.

  • Review: IT in Health Care Has Produced Modest Changes — So Far

    Large study of existing research shows incremental improvement in patient outcomes and productivity, without big employment changes.

  • New Imaging Method Reveals Concealed Objects

    Imaging scenes that lie outside an observer’s direct line of sight could greatly enhance search and rescue missions, such as finding a lost child in an abandoned factory, as well as military and police surveillance operations, such as exposing a hidden terrorist or enemy stronghold. Using submillimeter radiation naturally emitted by objects and people, researchers see around corners.

  • Europe Heat Wave: U.K. Records Hottest-Ever Temperature

    Western Europe continues to bake in extreme heat, with the UK recording a temperature over 40 degrees Celsius for the first time, and wildfires burning through French forests. Relief is expected later in the week.

  • Britain Isn’t Built to Withstand 40°C – Here Is Where Infrastructure Is Most Likely to Fail

    Climate change is intensifying heatwaves in the UK, an affluent country with the capacity and resources to adapt to warmer temperatures. Still, very little has been done over the past ten years to address overheating in buildings and the rising risk to critical infrastructure. The country is unprepared to handle temperatures of more than 38°C consistently for long periods, which is more common in Mediterranean countries.

  • Quantum-Inspired Approach Allows Lidar to Be used for Facial Recognition

    Quantum-inspired technique can be used to perform lidar imaging with a much higher depth resolution than is possible with conventional approaches. Lidar, which uses laser pulses to acquire 3D information about a scene or object, is usually best suited for imaging large objects such as topographical features or built structures due to its limited depth resolution. By capturing more details, new approach could make lidar useful for facial recognition.

  • Warning System for Dangerous Heavy Rain and Flash Floods

    In recent years, there have been repeated flash floods in Germany, some with devastating effects, which have been triggered by localized heavy rainfall. New project aims to provide prototypical warnings at different spatial scales, from the whole of Germany to individual federal states and down to the municipal level.

  • Water Resources to Become Less Predictable with Climate Change

    Many regions of Earth rely on the accumulation of snow during the winter and subsequent melting in the spring and summer for regulating runoff and streamflow. Water resources will fluctuate increasingly and become more and more difficult to predict in snow-dominated regions across the Northern Hemisphere.

  • New Computing Security Architecture Protects Sensitive Private Data

    Protecting sensitive information on the internet has become an essential feature for computing architectures. Applications that process such data must trust the system software they rely on, such as operating systems and hypervisors, but such system software is complex and often has vulnerabilities that can risk data confidentiality and integrity.

  • Safer Web Surfing with a New Method for Detecting Malicious Code Patterns

    With the ever-increasing importance of the Internet in our lives, there are growing attempts to exploit software vulnerabilities in our PCs for personal benefit. One way to do so is by infecting the victim’s PC with a malicious code injected through a website. A fast and reliable detection approach can analyze distribution patterns of malicious codes in websites.

  • U.S. Dominated by Remarkable Heat, Dryness

    June kicked off a very warm and dry start to meteorological summer for the U.S. The U.S. struck with 9 separate billion-dollar disasters so far this year. The average June temperature across the contiguous U.S. was 70.7 degrees F — 2.2 degrees above average.

  • Pegasus Spyware Maker NSO Is Conducting a Lobbying Campaign to Get Off U.S. Blacklist

    The cybersecurity firm has invested heavily in top lobbyists and law firms in an effort to lift restrictions on doing business in America. NSO is hoping the Israeli prime minister will raise the issue with Joe Biden when the two meet this week.
