...t the nature of migration, which can be seen as an adaptation to fluctuating resources. Susanne kesson and Anders Hedenstrm describe experimental approaches to the question of how migrants achieve their navigations, and suggest that future research will need to investigate a range of natural cues.

Scientists crack the genome of the parasite causing trichomoniasis

...eve the pathogen's large genome is likely to be an adaptation for its lifestyle. Trichomonas vaginalis is typically a pear-shaped organism. When it sticks to the vaginal wall, the parasite flattens, looking almost squashed. That flattening dramatically increases its surface area. The scientists hypothesize t...

Finding a cure for cancer: The holy grail of science

... response machinery, or a phenomenon of checkpoint adaptation (when the cell arrest is long-term and not irreversible) may allow the cell to escape from the DNA damage-imposed blockade and despite its damaged DNA, it may multiply. This can give birth to a tumour. Bartek and his team have found that if an inhi...

Blue eyes -- A clue to paternity

The laws of genetics state that eye color is inherited as follows: If both parents have blue eyes, the children will have blue eyes. If both parents have brown eyes, a quarter of the children ...

HIV gets a makeover

...or the HIV one -- and then another round of forced adaptation to create viruses that would multiply with vigor. The researchers dubbed their end result simian tropic HIV (stHIV): a form of HIV-1 that only differs from the original by about 10 percent, but can effectively infect primate cells and be used to te...
