Livestock farming produces large quantities of greenhouse gases, especially methane, which is particularly harmful to the climate. Among other things, it escapes during the storage of animal excrement, the slurry. A study now shows that methane emissions can be reduced by 99 percent through simple and inexpensive means. The method...

Illuminating the Science of Black Holes and Gamma-Ray Bursts Using High-Power Lasers
High-power lasers now create record-high numbers of electron-positron pairs, opening exciting opportunities to study extreme astrophysical processes, such as black holes and gamma-ray bursts.
Additive to Make Slurry More Climate-Friendly
Livestock farming produces large quantities of greenhouse gases, especially methane, which is particularly harmful to the climate.
Scientists Use Satellites To Track Earth ‘Greening’ Amid Climate Change
North Carolina State University researchers used satellite imagery and field sensors to estimate worldwide changes in plant leaf growth due to global warming.
Case study of rare, endangered tortoise highlights conservation priorities for present, future World Wildlife Days
Though wildlife trafficking has been effectively disrupted since the first World Wildlife Day -- established 50 years ago today via the 1973 Convention on International Trade in Endangered Species (CITES) of Wild Fauna and Flora -- a newly published case study on one of the world's rarest tortoise species, the...
Fluorescent protein sheds light on bee brains
An international team of bee researchers has integrated a calcium sensor into honey bees to enable the study of neural information processing including response to odors. This also provides insights into how social behavior is located in the brain.
Insights into the evolution of the sense of fairness
A sense of fairness has long been considered purely human -- but animals also react with frustration when they are treated unequally by a person. In a study with long-tailed macaques (Macaca fascicularis), researchers have now confirmed an alternative explanatory approach. A combination of social disappointment with the human experimenter...
Genomic study of indigenous Africans paints complex picture of human origins and local adaptation
An international team of researchers analyzed the genomes of 180 indigenous Africans from a dozen ethnically, culturally, linguistically, and geographically diverse populations. The results shed light on the origin of modern humans, historical migrations, linguistic evolution, and local adaptation, and lay the groundwork for more people to benefit from precision...
Robot Provides Unprecedented Views Below Antarctic Ice Shelf
High in a narrow, seawater-filled crevasse in the base of Antarctica’s largest ice shelf, cameras on the remotely operated Icefin underwater vehicle relayed a sudden change in scenery.
Keto vs Vegan: Study of Popular Diets Finds Over Fourfold Difference in Carbon Footprints
A new study from Tulane University which compared popular diets on both nutritional quality and environmental impact found that the keto and paleo diets, as eaten by American adults, scored among the lowest on overall nutrition quality and were among the highest on carbon emissions.
