The failure of SpaceX's latest Falcon launch brings at least one encouraging note: It confirms the daring of the private sector as it explores space flight possibilities. In this case, the rocket was to return itself safely from its mission and land on a barge.
A BCC Research report predicts the value of the worldwide self-monitoring health technologies market will hit $18.8 billion in 2019, up from $3.2 billion last year. The study also found that 81% of the roughly 21 million people who monitored their health using smartphones in 2013 were from the U.S., where self-tracking is expected to grow at a compound annual growth rate of 27.9% in the five-year period from 2014 to 2019.
A wood-burning incinerator draws on the high winds of northern Kenya to burn medical waste using a fifth of the fuel normally required. The Wamba incinerator can dispose of as much as 44 pounds of medical waste a day, and efforts are now aimed at designing an even more efficient device that uses the power of the sun.
Great communicators throughout history have used techniques that can be adopted and emulated by less confident speakers, writes Megan Allen. These orators know the power of a clear, succinct message, and also the importance of connecting with the audience while displaying their emotions.
The U.S. Navy will be calling on industry in September to advance 3D-printing technology with the goal of creating shipboard printers to produce spare parts only as needed. "We're developing quality [additive manufacturing] metal processes for naval applications with titanium, aluminum and stainless-steel alloys," said program manager Billy Short. Aviation and ground applications could follow.
In addition to third-generation nuclear reactors such as the AP1000 models under construction at operator Southern Co.'s Plant Vogtle in Georgia, proposals for fourth-generation reactors are already underway. While third-generation versions are light water reactors with advanced safety systems that improve on previous technology, fourth-generation reactors use substances such as pressurized gas or liquid metal to stay cool while running on used nuclear fuel from existing plants and other innovative fuel sources. "By 2025, we can have operating commercial Gen 4 reactors," said Samuel Brinton, a clean energy fellow at Third Way.
The National Security Agency can continue its bulk collection of telephone records for a six-month transitional period even after Congress voted to eliminate the program, the Foreign Intelligence Surveillance Court ruled.
Elon Musk's futuristic Hyperloop is now a reality -- at 1:24 scale. Mechanical engineering students at the University of Illinois have created the model using an oval-shaped metal tube and electromagnetic motors to move its vehicle at the scaled-down equivalent of 160 mph. However, the model uses roller bearings rather than the air bearings Musk envisioned.
An aircraft similar to the hoverbikes seen in "Star Wars" movies may become reality for the military in just a few years. The Army Research Laboratory in Maryland is working with a British company, Malloy Aeronautics, and U.S. defense contractor Survice Engineering to develop an aircraft that uses a motorcycle engine and small rotors to lift it as high as 9,000 feet. "The Army is looking at using it … close to the ground. So we are looking at technology to make sure it's safe in that kind of environment," Survice official Mark Butkiewicz.
President Barack Obama has unveiled rules to increase the salary threshold for workers to be automatically eligible for overtime pay. The rules, which could take effect in 2016, do not need congressional approval, although they will likely face pushback from Republicans and business groups.
