Modular Biosensor Patch

Researchers are identifying new biomarkers to help monitor cognition and stress in the human body and enhance human performance. Traditional biomarkers like heart rate, temperature, oxygen partial pressure, blood glucose, electrolyte concentration, and others have been correlated with cognition and stress states. However, the correlation is indirect. Molecular biomarkers with stronger and more specific links are preferred.

Making Flight Safer With the “Internet of Airplanes”

The Virtual Sky platform was developed to fuse and analyze flight sensor data correctly, reliably, and quickly. Virtual Sky would serve as a model extension of the FAA’s Next Generation Air Transportation System, a modernization of the National Airspace System that includes greater use of computer and satellite systems in air traffic elements like communication, navigation, weather, information management, and tracking.

New Flight Strategy Could Land Heavier Vehicles on Mars

The heaviest vehicle to successfully land on Mars is the Curiosity Rover at 1 metric ton. Sending more ambitious robotic missions to the surface of Mars, and eventually humans, will require landed payload masses in the 5- to 20-ton range. A recent study was conducted to determine how to land more mass.
