A breakthrough in high-speed, eye-safe LIDAR is made possible by heavy-metal-free quantum dots

By Lurker,
There are many different frequencies of light that reach Earth, some of which are visible to us and others of which are not. Because of its special characteristics, shortwave infrared (SWIR) stands out among these frequencies and is very helpful for Light Detection and Ranging (LIDAR) systems.
Like SONAR, which utilizes sound waves to determine distances, LIDAR employs laser pulses.
The danger of SWIR waves is that they do not reach the retina through the cornea and lens of the huma
Researchers develop holistic tool to help plan urban vacant lots

By Lurker,

Vacant lots, though overlooked or seen as eyesores by many, represent opportunities.
UConn College of Agriculture, Health and Natural Resources doctoral researcher Pan Zhang and Assistant Professor Sohyun Park, both in the Department of Plant Science and Landscape Architecture, have created a framework to help cities and community members assess and prioritize which lots will have the biggest impact—for everyone—if they are repurposed. Their research is published in the journal Sustainabili
Multi-frequency microwave model advances land surface monitoring

By Lurker,

A new study introduces the Community Land Active Passive Microwave Radiative Transfer Modeling platform (CLAP)—a unified multi-frequency microwave scattering and emission model designed to revolutionize land surface monitoring. This cutting-edge platform combines active and passive microwave signals to offer potentially accurate simulations of soil moisture and vegetation conditions.
By incorporating advanced interaction models for soil and vegetation, CLAP has the potential to address key
Finnish researchers map endangered wolverine habitats using satellite data

By Lurker,

Researchers at Aalto University have, for the first time, investigated the occurrence of wolverines across the whole of Finland using satellite imagery, field measurements, and snow track observations.
The wolverine, a predator typically found in the fells and forests of northern Finland, was classified as endangered in the country already in the 1980s. Although information on the species' historical range is limited, wolverines are known to have inhabited southern Finland as recently as th
Tern AI’s low-cost GPS alternative actually works

By Lurker,
We’ve all experienced that moment of frustration when the GPS glitches and you miss an exit on the highway. The team at Tern AI, which is building a low-cost GPS alternative, says that’s because the current technology is limited by its reliance on satellite positioning.
Tern AI says it has figured out how to locate the position of a vehicle using only map information and a vehicle’s existing sensor data. The company’s pitch: It’s a cheap system that doesn’t require any additional expensive
