This week's Question: MasterCard has tested facial biometrics for payment authentication and has now begun rolling out its MasterCard Identity Check, or "selfie pay," to a greater number of users. The biometric authentication app is available throughout Europe, including Austria, Belgium, the...

A research team led by faculty scientist Ali Javey at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has created a transistor with a working 1-nanometer gate — the smallest to date.

This week's Question: Solar Roadways — a startup developing solar powered road panels — will soon install the first solar road tiles in Sandpoint, Idaho. The transparent solar road panels contain colorful LEDs, which can be controlled by a computer to create the impression of signs and lines, without the need of...

NASA’s Jet Propulsion Laboratory has developed an advanced energy-storage device to accommodate portable devices, minimize emissions from automobiles, and enable more challenging space missions. The use of silicon for the anode of lithium ion (Li-ion) batteries is...

PyTMatrix is a Python interface to a T-matrix numerical scattering computation code originally developed at NASA GISS (Goddard Institute for Space Studies). It integrates into the NumPy/SciPy scientific framework. The software provides streamlined access to numerical T-matrix...

NASA’s Glenn Research Center is offering a sensor and actuator networking innovation applicable to smart vehicle or component control. This innovation requires no additional connectivity beyond the wiring providing power. This results in lower system weight, increased ease and flexibility...

Innovators at NASA’s Glenn Research Center have developed a microwave power module to power radar, communications, and/or navigation interchangeably. This high-efficiency, all-solid-state microwave power module (MPM) is based on a multi-stage distributed-amplifier design, which is capable of very wideband operation....

NASA’s Langley Research Center has created a collection of innovations for rapid, precise, and verified crimps. Wiring crimp failures can be a threat to safety and may lead to a loss of critical functions in high-risk applications, such as aerospace. In addition to the safety...

Innovators at NASA’s Glenn Research Center have developed a low-cost, high-efficiency solar cell that uses a thin layer of selenium as the bonding material between wafers. Selenium is a semiconductor, and it is also transparent to light at photon energies below the band gap. The...

Lithium-ion (Li-ion) cells are increasingly used in high-voltage and high-capacity modules. The Li-ion chemistry has the highest energy density of all rechargeable battery chemistries, but associated with that energy is the issue of catastrophic thermal runaway with a fire. With...

One of the main heritage tools used in scientific and engineering data spectrum analysis is the Fourier Integral Transform and its high-performance digital equivalent — the Fast Fourier Transform (FFT). The Fourier view of nonlinear mechanics that has existed for...
