A new study classifies different types of wildlife traffickers and sellers in two of Central Africa's growing urban centers, providing new insight into the poorly understood urban illegal wildlife trade.
Scientists have sequenced ancient DNA from soil for the first time and the advance will transform what is known about everything from evolution to climate change. The findings have been described as the 'moon landings' of genomics because researchers will no longer have to rely on finding and testing fossils to determine genetic ancestry, links and discoveries - and it is thanks to Stone Age black bears who defecated in a remote cave in Mexico 16,000 years ago.
New, detailed study of the Renland Ice Cap offers the possibility of modelling other smaller ice caps and glaciers with much greater accuracy than hitherto. The study combined airborne radar data to determine the thickness of the ice cap with on-site measurements of the thickness of the ice cap and satellite data. Researchers from the Niels Bohr Institute - University of Copenhagen gathered data from the ice cap in 2015, and this work has now come to fruition: More exact predictions of local climate conditions.
The Andes Mountains in South America are the world's longest mountain range and a hotspot of biodiversity. But the forest that climbs up this mountain range provides another important service to humanity. Andean forests are helping to protect the planet by acting as a carbon sink, absorbing carbon dioxide and keeping some of this climate-altering gas out of circulation, according to new research published in Nature Communications.
Researchers from the Singapore-MIT Alliance for Research and Technology developed a synthetic framework known as theory-based residual neural network (TB-ResNet) to improve individual decision-making analysis used in travel behaviour research. The research explains that data-driven and theory-driven models, which are generally used as separate methods that are conflicting, are actually highly complementary and can provide valuable insights into urban transportation planning.
Researchers and physicians from the Occupational Safety and Health Administration (OSHA) and UC San Francisco have found that deaths of workers using methylene chloride paint strippers are on the rise. The solvent is widely used in paint strippers, cleaners, adhesives and sealants.
Monitoring environmental compliance is a particular challenge for governments in poor countries. A new machine learning approach that uses satellite imagery to pinpoint highly polluting brick kilns in Bangladesh could provide a low-cost solution.

In a world in which biodiversity is increasingly under threat, and nature itself under siege, the role of human activities in driving ecosystem change has never more been apparent. But is all human activity bad for ecosystems? An international team of researchers suggests not.
It will take until at least 2080 before women make up just one-third of Australia's professional astronomers, an analysis published today in the journal Nature Astronomy reveals.
Our planet's worst mass extinction event happened 252 million years ago when massive volcanic eruptions caused catastrophic climate change. The vast majority of animal species went extinct, and scientists are still learning about the patterns of which animals went extinct and which ones survived, and why. In a new study in PNAS, researchers found that while extinctions happened rapidly in the oceans, life on land underwent a longer, more drawn-out period of extinctions.
