• Shutting Down Nuclear Power Could Increase Air Pollution

    Nearly 20 percent of today’s electricity in the United States comes from nuclear power. If reactors are retired, polluting energy sources that fill the gap could cause more than 5,000 premature deaths, researchers estimate.

  • From High to Low in 15 Years: Coal Continues Its Precipitous Decline

    The country’s power generators used more coal in 2007 than ever before — a little over one billion tons. This year, coal use by U.S. electric-power producers would likely not reach 400 million tons. Roughly 40 percent of the country’s current coal-fired capacity is set to close by 2030. “This is not an economic cycle that is simply going to go away,” says an expert. “It is a real phaseout across the industry of the use of coal.”

  • Sea-Level Rise Poses Particular Risk for Asian Megacities

    Sea-level rise this century may disproportionately affect certain Asian megacities as well as western tropical Pacific islands and the western Indian Ocean. Among the Asian megacities that may face especially significant risks: Chennai, Kolkata, Yangon, Bangkok, Ho Chi Minh City, and Manila.

  • How the U.S. Rail System Works

    A spate of train derailments, most notably in East Palestine, Ohio, has reinvigorated the debate over the nation’s railroad infrastructure. Here’s how U.S. rail could be brought up to speed.

  • Buildings Left Sanding in Turkey Offer Design Guidance for Future Earthquake-Resilient Construction

    The Feb. 6, 2023, earthquakes in Turkey and Syria put to the test advanced building technologies that can minimize damage and keep buildings functioning after a quake. Several hospitals built with one such technology – called a seismic isolation system – survived the earthquakes with almost no harm.

  • Texas Senate Moves to Set Aside Billions for Future Water Needs

    The Texas Senate on Monday passed a bill that would create a new state fund tailored for large or long-shot water supply projects, including marine desalination. The bill will advance to the House.

  • Polish Shale Gas May Be the answer to the EU's Energy Shortage

    Although there is currently no shale gas production in Europe, Polish energy experts say it could easily be brought back to the table to alleviate the European energy crisis.

  • AI Could Set a New Bar for Designing Hurricane-Resistant Buildings

    Being able to withstand hurricane-force winds is the key to a long life for many buildings on the Eastern Seaboard and Gulf Coast of the U.S. Determining the right level of winds to design for is tricky business, but support from artificial intelligence may offer a simple solution.

  • Kites Aim to Tap Unused High-Altitude Wind Power

    There is a growing interest in harvesting what are known as high-altitude winds. At a height of 200 meters (656 feet) and more, winds tend to blow stronger and more steadily than those closer to the ground. High-altitude winds remain a huge untapped source of renewable energy, but a race to the sky is well underway.

  • What Is the National Cybersecurity Strategy? What the Biden Administration Has Changed

    On 2 March 2023 the Biden administration released its first National Cybersecurity Strategy. Some of the key provisions in the Strategy relate to the private sector, both in terms of product liability and cybersecurity insurance. It also aims to reduce the cybersecurity burden on individuals and smaller organizations. It provides some innovative ideas that could strengthen U.S. cybersecurity in meaningful ways and help modernize America’s technology industry, both now and into the future.

  • Is Your Cybersecurity Strategy Undermined by These Six Common Pitfalls?

    Many security specialists harbor misconceptions about lay users of information technology, and these misconceptions can increase an organization’s risk of cybersecurity breaches. These issues include ineffective communications to lay users and inadequately incorporating user feedback on security system usability.

  • Preventing Fires and Explosions

    Lines in natural gas grids have to be maintained and serviced regularly. This entails using flares to vent the natural gas. With FlareSimulator, research scientists at the Fraunhofer Institute for Factory Operation and Automation IFF have developed an assistive tool that calculates the correct distance of flares to houses, trees and other nearby objects. This makes it easy to maintain minimum distances and prevent potential hazards and explosions.

  • New Method Helps Locate Deposits of Critical Metals

    The global shift to a carbon-free energy system is set to drive a huge increase in the demand for rare or limited earth minerals. This presents an urgent need to locate new sustainable sources of these elements. New technique could help locate new deposits of critical metals needed to enable the green-energy transition.

  • An Early Warning System for Landslides Protects Sitka, Alaska

    A hard rain was rattling against the rooftops of Sitka, Alaska, as day broke on August 18, 2015. Just before 10 a.m., a hillside gave way. A river of mud, rocks, and broken trees surged down the slope and crashed through the subdivision.

  • If the Price Is Right: Fusion's Future in the U.S. Could Come Down to Dollars and Cents

    Fusion energy is often hailed as a limitless source of clean energy, but new research suggests that may only be true if the price is right. The researchers say that the engineering challenges of fusion energy are only part of the problem — the other part lies in economics.
