Bi-Directional Energy Cascades and the Origin of Kinetic Turbulence in the Solar Wind

The kinetic turbulence of solar wind originates in the solar corona. The solar wind carries the fluctuations and escapes from the corona along the open magnetic field lines, and enters into the interplanetary space. The energy exchange among waves and particles...

Global Series Solutions of Nonlinear Differential Equations with Shocks using Walsh Functions

An orthonormal basis set is introduced for use in generating global solutions to nonlinear differential equations with shocks. By global, it is meant that a single series solution is generated that is valid over the entire domain, not a separate...

Correcting the Antenna Temperature of an Earth-Observing Microwave Instrument for Extraterrestrial Contamination

Microwave antennas deployed for spaceborne radiometers are diffraction-limited, with typical beam efficiency of about 90%, and provide relatively poor selectivity against radiation from celestial bodies (Moon, Sun, galaxy) when they...

Space Habitability Observation Reporting Tool (iSHORT)

As documented by the Human Research Program, there is a need for tools to aid in assessing habitability in space vehicles/habitats. Currently, human factors and habitability feedback is collected during post-mission debriefs that may occur up to several months following the end of a mission....

Geodesolver for the Geodesic Equation

NASA has a need to determine the distribution of dark matter around planets like Earth. Doing so necessitates the ability to repeatedly solve the geodesic equation in simulations of weakly interacting particles streaming through bodies described by a Schwarzschild metric. Geodesolver numerically solves the...

Passive In-Situ Gas and Chemical Sensor

In many chemical processes, it is often desirable to detect the presence, quantity, and/or qualities of certain chemicals of interest; for example, in many closed chemical processes (either batch or...

Recyclable Polymer Exhibits Practical Properties of Plastics

A polymer was discovered that possesses many of the same characteristics as plastics, such as light weight, heat resistance, strength, and durability. But the new polymer, unlike...

Solving a Problem that Plagues Scanning Tunneling Microscopes

Researchers at the University of Texas at Dallas have solved a longstanding problem that has been plaguing the scanning tunneling microscope for more than 35 years: How to prevent the tip of a scanning tunneling microscope from crashing into the surface of a material during imaging or...

Seeing the Brain’s Electrical Activity

Neurons in the brain communicate via rapid electrical impulses that allow the brain to coordinate behavior, sensation, thoughts, and emotion. Scientists who want to study this electrical activity...

Lens-Free Fluorescent Microscope

Rice engineers have developed a wide-field microscope thinner than a credit card, small enough to sit on a fingertip and capable of micrometer resolution over a volume of several cubic millimeters.

See Objects Hidden Around Corners

A driverless car is making its way through a winding neighborhood street, about to make a sharp turn onto a road where a child’s ball has just rolled. Although no person in the car can see that ball, the...

Transparent Eel-Like Soft Robot Swims Silently Underwater

An eel-like robot was developed that can swim silently in salt water without an electric motor. Instead, the robot uses artificial muscles filled with water to propel itself. The...
