With recent studies having established the presence of nano and microplastic particles in the respiratory systems of both human and bird populations, a new University of Technology Sydney (UTS) study has modelled what happens when people breathe in different kinds of plastic particles and where they end up.
Artificial Intelligence Enhances Monitoring of Threatened Marbled Murrelet
Artificial intelligence analysis of data gathered by acoustic recording devices is a promising new tool for monitoring the marbled murrelet and other secretive, hard-to-study species, research by Oregon State University and the U.S. Forest Service has shown.
Improved AI Process Could Better Predict Water Supplies
A new computer model uses a better artificial intelligence process to measure snow and water availability more accurately across vast distances in the West, information that could someday be used to better predict water availability for farmers and others.
Malaria may shorten leukocyte telomeres among sub-Saharan Africans
The length of telomeres in white blood cells, known as leukocytes, varies significantly among sub-Saharan African populations, researchers report. Moreover, leukocyte telomere length (LTL) is negatively associated with malaria endemicity and only partly explained by genetic factors.
Activation of innate immunity: Important piece of the puzzle identified
Researchers have deciphered the complex interplay of various enzymes around the innate immune receptor toll-like receptor 7 (TLR7), which plays an important role in defending our bodies against viruses.
Wild orangutan treats wound with pain-relieving plant
A wild orangutan was observed applying a plant with known medicinal properties to a wound, a first for a wild animal.
Microneedles and suction cup for blood diagnostics, modeled on leeches
A new device for taking blood samples uses microneedles and a suction cup instead of a large needle. People with a phobia of needles stand to benefit. More blood can be obtained than with the classic finger prick, making diagnostic measurements more reliable. Because the device can be produced at...
Medical school scientist creates therapy to kill hypervirulent bacteria
Researchers are on a mission to kill drug-resistant bacteria, and a new study has identified a therapy that can penetrate the slime that such infections use to protect themselves from antibiotics.Researchers have shown that an antimicrobial peptide from cows has potential for treating incurable infections from the bacterium Klebsiella pneumoniae....
EPA underestimates methane emissions from landfills, urban areas
The Environmental Protection Agency (EPA) is underestimating methane emissions from landfills, urban areas and U.S. states, according to a new study. The researchers combined 2019 satellite observations with an atmospheric transport model to generate a high-resolution map of methane emissions, which was then compared to EPA estimates from the same...
Archaea can be picky parasites
A parasite that not only feeds of its host, but also makes the host change its own metabolism and thus biology. Microbiologists have shown this for the very first time in a specific group of parasitic microbes, so-called DPANN archea. Their study shows that these archaea are very 'picky eaters',...
