Internet fiber optics could provide valuable insight into geological phenomena

Fiber-optic cables run underneath nearly all city grids across the United States and provide internet and cable TV to millions, but what if those systems could also provide valuable information related to hazardous events such as earthquakes and flooding? A team of researchers at Penn State have found they can do just that.
The scientists are using fiber-optic distributed acoustic sensing (DAS) technology to turn existing telecommunication infrastructure that is already installed underground into a valuable resource for monitoring ground vibrations.

NASA is seeking proposals for ground and flight demonstrations of integrated megawatt-class powertrain systems for subsonic aircraft. The deadline for proposals for this solicitation is 5 p.m. EST April 20.
The demonstrations will help rapidly mature and transition integrated Electrified Aircraft Propulsion (EAP) technologies and associated EAP vision systems for introduction into the global fleet by 2035. Integrated EAP concepts are rapidly emerging as potentially transformative solutions to significantly improve the environmental sustainability of the next generation of subsonic transport vehicles. EAP electrical systems are being developed to replace or boost fuel-burning aircraft propulsion systems, analogous to how electric or hybrid motors are used in automobiles.

Using a novel technology Griffith University Institute for Glycomics researchers are closer to the development of a new vaccine aimed at preventing the deadly Streptococcus A (Strep A), which kills more than 500,000 people globally per year.
“Strep A colonises the upper respiratory tract and skin. Repeated infections can cause auto-immune complications and progress to invasive and immune-mediated diseases such as rheumatic fever and rheumatic heart disease,” says lead researcher Dr Manisha Pandey.
“There is currently no vaccine available as immunity to Strep A in humans takes years to develop. This is because it is highly virulent and subverts innate and acquired immunity.”
