A 'private bandwidth' for communication in bats: Evidence from insular horseshoe bats
...unication may have crucial implications for social interactions and sexual behaviour. Noticeably, in mainland regions where the three species occur together, some 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 al...Which came first, the moth or the cactus?
...and said. Traditional theory of such mutualistic interactions leads to predictions of unbounded population growth or instability and eventual doom due to one species overexploiting another. These predictions clearly don't square with what Holland and his students see happening in the Sonoran Desert, where both ...Does the desire to consume alcohol and tobacco come from our genetic makeup?
... desires is multifactorial and a result of complex interactions with the environment. Adoption and twin studies have shown that the use of these substances is likely to be inherited. Such studies have provided evidence that ones sex can influence the genetic factors for alcohol and tobacco use. In an attempt t...Evolution is driven by gene regulation
... have now shown that we can functionally map these interactions and identify the specific targeted promoters, said Snyder. We were startled to find that even the closely related species of yeast had extensively differing patterns of regulation. In this study, the authors found the DNA binding sites by aiming at...A study by the MUHC and McGill University opens a new door to understanding cancer
...his new study reveals that ubiquitin also promotes interactions between proteins known as Cb-b. In a healthy patient, Cb-b is activated when a growth factor attaches itself to the surface of a cell, its role being to mitigate the cell proliferation and growth mechanisms induced by the factor.
