The study's results come as the Federal Aviation Administration (FAA) considers a proposal to raise the mandatory age of retirement for commercial airline pilots to 65 from the current age of 60.
For the study, researchers tested 118 non-commercial airline pilots, age 40 to 69, annually for three years. All pilots were currently flying, had between 300 and 15,000 hours of total flight time, and had a FAA medical certificate. Pilots were tested on accuracy of executing communications, traffic avoidance, scanning cockpit instruments to detect emergencies, and executing a visual approach landing.
The study found while older pilots initially performed worse than younger pilots, older pilots showed less of a decline in overall flight summary scores than younger pilots, and over time their traffic avoidance performances improved more than that of younger pilots. The study also found pilots with advanced FAA pilot ratings and certifications showed less performance decline over time, regardless of age.
"These findings show the advantageous effect of prior experience and specialized expertise on older adults' skilled cognitive performances," said study author Joy L. Taylor, PhD, with the Stanford/VA Aging Clinical Research Center in Palo Alto, California. "Our discovery has broader implications beyond aviation to the general issue of aging in the workplace and the objective assessment of competency in older workers."
Researchers suggest that pilots with advanced FAA pilot ratings may maintain performance over time due to a mechanism of preserved task-specific knowledge, known as crystallized intelligence, which is similar to what is seen in music or expert chess playing.

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.
Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
