The construction of an 1100-foot tall multi-use skyscraper is underway in downtown Los Angeles. At 2.1 million square feet and 73 stories tall the Wilshire Grand will be the tallest building west of the Mississippi River. While this is an impressive height, especially for L.A., it is dwarfed, worldwide, by roughly 40 structures. The majority of these buildings, around 34, exist outside of the U.S.
Non-military drones are growing in popularity with the use by local police departments traffic reporters, and now the oil and gas industry is looking to get into the action. Researchers and industry alike are hard at work developing new technologies to improve methane detection in hydraulic fracturing operations that are compatible with drones. Many corporations currently use varied forms of aircraft, such helicopters and satellites, equipped with laser sensors or infrared cameras to detect methane. Lighter, less expensive, faster, and more sensitive sensors currently in development are making the use of drones more appealing.

Since the Oso landslide, the emerging question in many meetings, panel discussions and brainstorming sessions is about other slopes across the country having a significant collapse potential with the deadly effects as the Oso event. Geotechnical engineer Joe Wartman, member of the scientific team studying the landslide answers that it is not possible to know. The reason for this being primarily the lack of data.
Four new craters in the Siberian permafrost in northern Russia are raising fears that global warming may be causing underground gas explosions. Scientists are still investigating the causes for the crate formation stating that this could be the same phenomenon that formed the Bermuda Triangle.
Engineers at the Technical University of Munich (TUM) have come up with a way to prevent concrete spalling caused by excessive temperature built up during a tunnel fire. The new technology consists of fibers added in the concrete but the changes in concrete behavior remain still to be investigated.
