High-resolution images from satellite company Planet are revealing glimpses of some of the fires currently devastating the Amazon rainforest. While many of the images currently being shared on social media and by news outlets are from past fires — some from as long as 15 years ago — satellites can provide a near real-time view of what’s unfolding in the Amazon. With near-daily overflights and high-resolution imagery, Planet’s constellation of satellites is providing a clear look at some of the fires now burning in the Brazilian Amazon.

The Seattle-based Amazon.com has applied for its brand to be a generic top-level domain name (.amazon), but South American governments argue this would prevent the use of this internet address for environmental protection, the promotion of indigenous rights and other public interest uses. Along with dozens of other disputed claims to names including ".patagonia" and ".shangrila", the issue cuts to the heart of debates about the purpose and governance of the internet.

Energy efficiency gains are failing to keep pace with the Internet's rapid rate of expansion, says a new paper published in the journal Science. Noting that the world's data centers already consume 270 terawatt hours and Internet traffic volume is doubling every three years, Diego Reforgiato Recupero of the University of Catania argues for prioritizing energy efficiency in the design of devices, networks, data centers, and software development. Recupero highlights two approaches for improving efficiency: smart standby and dynamic frequency scaling or CPU throttling.

A newly discovered light-producing cockroach, Lucihormetica luckae, may have already been driven to extinction by a volcanic eruption in Ecuador. The species, only formally described by scientists this year, hasn't been spotted since the Tungurahua Volcano erupted in July 2010. The new species was notable because it represented the only known case of mimicry by bioluminescence in a land animal. Like a venomless king snake beating its tail to copy the unmistakable warning of a rattlesnake, Lucihormetica luckae's bioluminescent patterns are nearly identical to the poisonous click beetle, with which it shares (or shared) its habitat.

The Kihansi Spray Toad went extinct in the wild in 2005 when its habitat in Tanzania was destroyed by a dam. However conservationists at the Bronx Zoo managed to maintain a captive population which is now large enough to allow a bold experiment to move forward: reintroducing the toad into its old habitat. To make the once tropical gorge moist again, engineers have designed an artificial misting system that should allow toads to survive in the wild. The effort marks what may be the first time conservationists have ever re-established an "extinct" species in a human-engineered ecosystem.

A new tool developed by NASA and other researchers shows where forest is being chopped down on a quarterly basis. The global forest disturbance alert system (GloF-DAS) is based on comparison of MODIS global vegetation index images at the exact same time period each year in consecutive years. GloF-DAS could help users detect deforestation shortly after it occurs, offering the potential to take measures to investigate clearing before it expands.

Google has populated several major cities with more than 80 million virtual trees based on an automated process that identifies trees in satellite images. The realistic 3D representations are based on actual tree species found in urban areas. But Google has also extended realistic tree coverage to rainforests in Africa, Mexico, and the Amazon
