Not only did they demonstrate the strategy's abundance, but they also discovered tools that control it and send signals that tell bacteriophage viruses to flip from chill (lysogeny) into kill (lysis) mode. They showed that in polylysogeny, phages can coexist, their viral DNA or RNA hidden tucked inside the bacterium's own, replicating right along with the cells. But the infiltrating phages aren't exactly peaceful; it's more like mutually assured destruction. And the tenuous detente lasts only until something triggers one or more of the phages to switch into kill mode.

They hijack a little-known piece of the cell's DNA repair function to close themselves into a ring-like shape and then create a matching double strand. The finding upends 40 years of conventional wisdom and may offer new insights into cancer, viral infections and immune responses. It could also offer a new way to insert sequences into the genome.

A recent study led by environmental scientists provided the first evidence of frequent interactions between viruses and bacteria in human-made environments. It found that viruses can potentially help host bacteria adapt and survive in nutrient-depleted human-made environments through a unique gene insertion.

Fri, 30 Jun 2023 12:31:22 EDT //www.koonmotors.com/releases/2023/06/230630123122.htm Virus-like transposons wage war on the species barrier //www.koonmotors.com/releases/2023/06/230629193248.htm Scientists have known for decades that genes can be transferred from one species to another, both in animals and plants. However, the mechanism of how such an unlikely event occurs remained unknown. Now, researchers identify a vector of horizontal gene transfer (HGT) in worms. The findings could lead to the discovery of further vectors of HGT in eukaryotes and might find applications in pathogen control. Thu, 29 Jun 2023 19:32:48 EDT //www.koonmotors.com/releases/2023/06/230629193248.htm A new species of mosquitoes found in Finland -- official count of species now at 44 //www.koonmotors.com/releases/2023/06/230629125737.htm The mosquito species Culex modestus has been found in Finland for the first time. In Southern Europe it is known to spread West Nile virus, but it is highly unlikely for the disease to occur in Finland. Culex modestus has become the 44th mosquito species found in Finland, and the northernmost record of the species in Europe. The previous findings closest to Finland, but further south, have been made in the Leningrad Province in Russia and in Skåne in Sweden.
