 | A type of beetle that lives its entire life burrowing through stored grain has been found to lack full colour vision, and what's more the vision it does have breaks the rules. Most other insects have trichromatic vision -- they are sensitive to ultraviolet, blue and long wavelength light. Scientists now reveal that this beetle has lost photoreceptors that are sensitive to blue wavelengths. ...> Full Article |
Researchers have solved the structure of a DNA-protein complex that is crucial in the spread of antibiotic resistance among bacteria. Knowing this structure also provides fundamental insight into how cells successfully divide into two new cells with intact DNA.

The adaptive significance of the unique ability in many primates to distinguish red hues from green ones (i.e., trichromatic color vision) has always enticed debate among evolutionary biologists. The conventional theory is that primates evolved trichromatic color vision to assist them in foraging, specifically by allowing them to detect red/orange food items from green leaf backgrounds. However, the results from several empirical studies have called into question the extent to which trichromacy functions in foraging and if it provides a performance advantage over dichromatic primates (who lack red-green color vision). Other studies have suggested that trichromacy evolved in primates so that they could use physical traits like red skin in socio-sexual communication, such as a male providing information to a female about his mate quality.
