CyberTracker's software, developed in collaboration with indigenous communities, enables nearly anyone to collect complex biodiversity data. Even individuals who are illiterate can collect detailed data.
Researchers analyzed 1.8 billion genetic letters from over 9,500 species of flowering plants. The research reveals the evolutionary history of flowering plants.
Flash droughts occur suddenly and quickly, but now researchers at NASA's Jet Propulsion Laboratory have found a way to detect them early. Plants' "glow" diminishes before a flash drought, and this change can be observed by satellites.
Scientists have identified the fundamental components of sperm whale communication. Through the analysis of over 8,700 clips of sperm whale clicks, a complex communication system resembling a phonetic alphabet has been revealed.
According to the Global Footprint Network, ecological "overshoot" occurs when human demand exceeds the regenerative capacity of natural ecosystems. The later in the year this day occurs, the better. (But the model also has clear flaws.)
A study published in Science, in which 59,000 people in 63 countries were surveyed, showed that 86% "believe" in climate change. 86% think that people in their country "should try to combat global warming." However, they wrongly believe that others do not think the same.
