A cheap charcoal air filter can reduce nitrogen dioxide (NO2) inside vehicles by as much as 90%, compared to levels outside the vehicle.
Most detailed geological model reveals Earth’s past 100 million years
Previous models of Earth's recent (100 million years) geomorphology have been patchy at best. For the first time a detailed continuous model of the Earth's landscape evolution is presented, with potential for understanding long-term climate and biological development.
Livestock farming: Additive to make slurry more climate-friendly
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...
Wildfires in 2021 emitted a record-breaking amount of carbon dioxide
Carbon dioxide emissions from wildfires, which have been gradually increasing since 2000, spiked drastically to a record high in 2021, according to an international team of researchers.
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...
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...
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.
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...
Wisconsin cave holds tantalizing clues to ancient climate changes, future shifts
A newly published study of a stalagmite found in Cave of the Mounds reveals previously undetected history of the local climate going back thousands of years. Researchers describe evidence for an ice age punctuated by massive and abrupt warming events across much of the Northern Hemisphere.
Bald eagles aren’t fledging as many chicks due to avian influenza
Bald eagles are often touted as a massive conservation success story due to their rebound from near extinction in the 1960s. But now a highly infectious virus may put that hard-fought comeback in jeopardy. New research showed highly pathogenic avian influenza, also known as H5N1, is killing off unprecedented numbers...
