Drones Monitor Chimpanzee Habitat in Tanzania

Drones Monitor Chimpanzee Habitat in Tanzania

Ecologist Jeff Kerby is using Unmanned Aircraft Systems (UASs), or drones, to count chimpanzee nests and monitor their habitat in Tanzania's Ugalla Forest. Such counts typically are performed on foot, but UASs allowed researchers to cover a much larger area at reduced time and cost.

EU Conducting Unmanned Disaster-Monitoring Flights

EU Conducting Unmanned Disaster-Monitoring Flights

The European Union has been conducting simulated flood-disaster situations monitored by Unmanned Aircraft System (UAS) technology. The Driving Innovations in Crisis Management for European Resilience (DRIVER) project features a D-CODE research aircraft, a Do-228, circling over the simulated disaster, taking situational images in real time, which rescue workers can use to coordinate the disaster response.

How Many Trees Are on Earth?

How Many Trees Are on Earth?

According to a tally by an international team of scientists, there are roughly 3 trillion trees on Earth”more than seven times the number previously estimated. The study also finds that approximately 15 billion trees are cut down each year; since the onset of agriculture about 12,000 years ago, the number of trees worldwide has dropped by 46 percent.

Neutrino Map Exposes Nuclear Activity

Neutrino Map Exposes Nuclear Activity

A map published in Nature Scientific Reports shows what the world would look like if we could see the trillions of neutrinos that emanate from the surface of the planet each second. Dark spots on the map indicate nuclear reactors and parts of Earth's crust rich with radioactive uranium and thorium, which emit neutrinos when they decay.

Hubble Records Twin Jet Nebula Expansion

Hubble Records Twin Jet Nebula Expansion

A new image from the NASA/ESA Hubble Space Telescope captures the Twin Jet Nebula's shells and knots of expanding gas, as two iridescent lobes of material stretch outwards from a central star system. Within these lobes, two huge jets of gas are streaming from the star system at speeds in excess of 1 million kilometers (621,400 miles) per hour.

ABoVE Campaign to Examine Climate Change in Arctic

ABoVE Campaign to Examine Climate Change in Arctic

As part of a broad effort to study the environmental and societal effects of climate change, NASA has begun a multiyear field campaign to investigate ecological impacts of the rapidly changing climate in Alaska and northwestern Canada, such as the thawing of permafrost, wildfires and changes to wildlife habitats.
