Genomes of tapeworms studied
Researchers study the genomes of four tapeworm species to find adaptations that helped them evolve into parasites.
Genetics
Differences in mutation rates may lead to faster evolution
In Bacillus subtilis, there are higher rates of mutation in genes found on the lagging strand during replication as opposed to those found on the leading strand. This could lead to faster evolution of these genes!
Quality control of DNA replication
Researchers examine how cells know to make only one copy of DNA before division.
Analysis of bat genomes provides insight on flight evolution
Flight adaptation in bats may have had an inadvertent negative effects on immune system function, and potentially also on life expectancy.
Analysis of pig genome provides insight to evolution
These researchers compared the genomes of wild and domestic pigs from around the globe. Turns out these nosy creatures have a lot of genes related to olfaction.
Visualization of important protein molecules
This paper uses total internal reflection microscopy (TIRF) to visualize single molecules of proteins that are important in decoding, copying, and rearranging DNA.
Antibiotics in early life alter the gut microbiome
Administration of antibiotics is shown to alter the gut microbiome in mice. Significant changes in taxonomy and metabolic gene expression were observed.
