Hybrid sliding-rocking bridge columns are more earthquake-resistant

Researchers are developing bridge columns that are earthquake-resistant. Credit: Texas A&M University Bridges make travel faster and more convenient, but, in an earthquake, these structures are subject to forces that can cause extensive damage and make them unsafe. Now civil and environmental engineer Petros Sideris of Texas A&M University is leading an NSF-funded research project… read more »

Ransomware attacks on cities are rising

Credit: Shutterstock A ransomware campaign that targeted 23 US cities across Texas has raised serious concerns about the vulnerability of local governments and public services to cyber-attacks. These events come not long after similar attacks on governmental and business organizations in Indiana, Florida and elsewhere.

Delivering new concepts for urban citizens

Engineers, data scientists and architects will have to work more closely together in the cities of the future. Credit: Swinburne University of Technology The city could be thought of as a living organism that requires inputs of energy, nutrients, and water and exudes wastes. Traditionally, engineers designed and managed the systems that bought energy and… read more »

Researcher finds that U.S. wireless networks are throttling video streaming 24/7

A new study by David Choffnes, an assistant professor of computer and information science at Northeastern, found that almost all wireless carriers pervasively slow down internet speed for video streaming, even when networks are not overloaded.

ONR tech makes sure aviators and aircraft are a perfect fit

Nick Sievert, a machine learning developer at Naval Surface Warfare Center Dahlgren, uses the computerized Anthropometric Measurement Device to measure a student naval aviator to gauge what type of aircraft cockpit will best accommodate the aviator’s body. The device, developed through support from the Office of Naval Research Global TechSolutions program, features enhanced optical scanning… read more »

Sensitive data from a US anti-terror program was easily available for years, records show

Credit: CC0 Public Domain The Department of Homeland Security stored sensitive data from the nation’s bioterrorism defense program on an insecure website where it was vulnerable to attacks by hackers for over a decade, according to government documents reviewed by the Los Angeles Times. The data included the locations of at least some BioWatch air… read more »
