Apr. 8, 2024 Scientists describe a new mechanism impacting the phage-bacterial arms race, a nanosized epibiotic parasite, TM7x, which helps its host bacterium (a Schaalia odontolytica strain called XH001) achieve resistance to lytic ...

Apr. 29, 2024 Researcher discovered that two species in the genus Angelica are pollinated primarily by hornets. This overturns the conventional belief that Angelica species are 'generalists,' meaning that there is not one primary pollinator but a variety of species. As hornets are rarely primary pollinators, the discovery also impacts future ecological research and conservation ...

Apr. 29, 2024 Many bacteria produce substances to gain an advantage over competitors in their highly competitive natural environment. Researchers have discovered a new so-called lantibiotic, namely epilancin A37. It is produced by staphylococci that colonize the skin and acts specifically against their main competitors there, the corynebacteria. This specificity is presumably mediated by a very special ...

Apr. 25, 2024 Researchers have published a comprehensive study on the invasion of lionfish in the Mediterranean Sea, highlighting a rapid spread and the potential ecological impacts. The research shows the lionfish species Pterois miles has significantly expanded its territory in the Mediterranean since the invasion began around ten years ago. The invasive species has established presence in the eastern ...

Apr. 29, 2024 Europe's forests have already been severely affected by climate change. Thousands of hectares of trees have already died due to drought and bark beetles. Scientists have now investigated which trees can be used for reforestation. Their findings: only a few tree species are fit for the future, such as English oak in the UK. However, mixed forests are important for the survival of forests, ...

Apr. 23, 2024 Bioluminescence first evolved in animals at least 540 million years ago in a group of marine invertebrates called octocorals, according to the results of a new study. The study focuses on an ancient group of marine invertebrates that includes soft corals, pushes back the previous oldest dated example of trait by nearly 300 million ...

Apr. 25, 2024 'Bookworm' is a cute thing to call a voracious reader, but actual bookworms -- as well as microorganisms and time -- break down the flour pastes commonly used to keep old publications in one piece. Now, researchers have analyzed the proteins in wheat-based glues applied in historic bookbinding to provide insights on their adhesiveness and how they degrade. This information could help conservators ...
