Fossil fuel-free jet propulsion with air plasmas

Humans depend on fossil fuels as their primary energy source, especially in transportation. However, fossil fuels are both unsustainable and unsafe, serving as the largest source of greenhouse gas emissions and leading to ...

Broadband invisibility in the microwave range

(PhysOrg.com) -- In the series Star Trek, Klingons and Romulans have spaceships outfitted with cloaking devices that hide their presence from sight, as well as from the sensors of their rivals' spaceships. Unlike current ...

'Quantum dot' technology may help light the future

Advances at Oregon State University in manufacturing technology for "quantum dots" may soon lead to a new generation of LED lighting that produces a more user-friendly white light, while using less toxic materials and low-cost ...

Novel method for easier scaling of quantum devices

In an advance that may help researchers scale up quantum devices, an MIT team has developed a method to "recruit" neighboring quantum bits made of nanoscale defects in diamond, so that instead of causing disruptions they ...

Novel metamaterial sensor provides bigger picture
