KCE Structural Engineers, a firm that is part of the team investigating the partial collapse of the Champlain Towers South condominium in Surfside, Fla., has determined one nearby building of a similar age needs further structural investigation, and another should be shored. The determinations come as the National Institute of Standards and Technology prepares for the technical phase of its investigation. NIST is capturing high- and low-resolution lidar scans of the site, and radio frequency identification chips have been used to tag pieces of evidence.
Japan has proposed a metro project in Panama would include a 3.1-mile tunnel 210 feet under the Panama Canal. The tunnel would replace previously rejected plans to build a fourth bridge over the canal for the metro.
Cities across Europe are becoming greener and less car-centric. Carolin Werthmann explores several examples, including ambitious CO2-reduction goals in Vienna, the use of smart planning technology in Oslo and innovations being implemented in smaller German cities.
Asphalt modified with rubber from used tires offers economic, performance and environmental advantages for highway agencies, according to a report by the US Tire Manufacturers Association, the University of Missouri and nonprofit The Ray. The report calls for additional research on the life cycle effects of the material as well as its properties and characteristics.
The potential for energy recovery and mineral recycling from construction and demolition materials will be the subject of a study by the US Army Corps of Engineers, Holcim and its Geocycle unit. The study will begin with a waste characterization analysis.
Big data collected from cell phones to track local resident traffic patterns can support real-time evaluation of how well a community recovers from disasters. Researchers at Texas A&M University who compiled such data after Hurricane Harvey have produced a framework that can be applied in the aftermath of any other natural disaster.
Adding red and blue pigments to concrete yields little effect, but green pigments tend to weaken the concrete, according to researchers at Xi'an Jiaotong-Liverpool University. Green pigment was expected to add strength due to the presence of chromium oxide, but the opposite result is traced to impurities introduced in the pigment's production.
A soft robotic hand dexterous enough to beat the first level of Super Mario Bros. was 3D printed in a few hours thanks to a single process that left no need for subsequent assembly. The hand's need for complex microfluidic circuits complicated the 3D printing process, but researchers with the University of Maryland overcame that obstacle with the use of a multimaterial printer that solidifies one layer before moving on to the next.
The term robot comes from Karel Čapek's play "R.U.R.: Rossum's Universal Robots". The play depicts a factory where thousands of synthetic humanoids run and operate the facility, replacing their human counterparts. The robots were so efficient; they reduced production costs by 80 percent. The word robot comes from the Czech word robota.

Duke University engineers have designed a special 3D printer that produces titanium scaffolding to allow bone to grow in patients who suffer breaks. The technology could one day be used in other types of reconstructive surgery, said professor Kenneth Gall.
