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',...
Therapy to kill hypervirulent bacteria developed
A study has identified a therapy that can penetrate the slime that such infections use to protect themselves from antibiotics. Scientists showed that an antimicrobial peptide from cows has potential for treating incurable infections from the bacterium Klebsiella pneumoniae. The bacteria, commonly found in the intestines, is usually harmless. It...
Father’s gut microbes affect the next generation
Researchers changed the composition of the gut microbiota in male mice through common antibiotics, inducing a condition called dysbiosis, and found that: - Mouse pups sired by a dysbiotic father show significantly lower birth weight, and have increased risk of growth disorders and postnatal mortality.
Roadmap to close the carbon cycle
Reaching net-zero carbon emissions goals requires finding transformative paths to manage carbon in difficult-to-electrify economic sectors.
Calcium can protect potato plants from bacterial wilt
Scientists have discovered that calcium plays a significant role in enhancing the resistance of potato plants to bacterial wilt.
Novel genetic plant regeneration approach without the application of phytohormones
Conventional plant regeneration approaches by cell culture require the external application of plant growth regulators, including hormones. However, optimizing culture conditions can be laborious. Now, researchers have developed a novel plant regeneration system that omits the need for hormone application by genetically regulating the expression of genes that control plant...
Revised dating of the Liujiang skeleton renews understanding of human occupation of China
Researchers have provided new age estimates and revised provenance information for the Liujiang human fossils, shedding light on the presence of Homo sapiens in the region. Using advanced dating techniques including U-series dating on human fossils, and radiocarbon and optically stimulated luminescence dating on fossil-bearing sediments, the study revealed new...
Every breath you take: Study models the journey of inhaled plastic particle pollution
With recent studies having established the presence of nano and microplastic particles in the respiratory systems of both human and bird populations, new research has modeled what happens when people breathe in different kinds of plastic particles and where they end up.
