A 'private bandwidth' for communication in bats: Evidence from insular horseshoe bats
...e overlap does occur. Bats move long distances, so gene
flow may operate between populations living in sympatry (i.e. occurring in the same areas) and allopatry (living in separate areas) with R. mehelyi, countering the establishment of local differences. Being sufficiently isolated (ca. 180 km distant) f...

...y TNT. In the new study, researchers inserted a gene
for a TNT-transforming bacterial enzyme into a tobacco plant. Then they tested the plants effect on TNT-contaminated soil in comparison to regular tobacco plants grown in the same soil for several weeks. The genetically modified plants significantly...

pool of this species is getting more and more fragmented, and gene

Gene regulation, not just genes, is what sets humans apart

regulation, the complex cross-talk that governs when genes are turned on and off, appears to be significantly different. Positive selection, the process by which genetic changes that aid survival and reproduction spread throughout a species, has ...
Green tea boosts production of detox enzymes, rendering cancerous chemicals harmless
..., Chow added. Green tea catechins somehow increase gene
expression of these enzymes, which can be an advantage to people with low levels to start with. Green tea has long been of interest to researchers given studies that have shown populations in which it is often consumed, such as the Chinese and Japa...
