...ls increased. These findings established a direct correlation between climate change and population size, but how did individual voles and pocket gophers respond genetically to these episodes of global warming and cooling?

...with a plant's ability to accumulate nickel. "This correlation makes good sense," Salt said. "If you accumulate a lot of nickel, then you will need the ability to resist high levels of oxidative stress." Correlation doesn't prove causation, however, so the next step in Salt's study was to establish that glutath...Analysis of gene expression in lymphoid cells can determine lymphoma cancer

Thus, the precise mechanism behind this resistance remained unknown. A specific mlo-resist...Living at home helps young mothers stay in school

Rather, some characteristics of the young mothers (such as their maturity level) may have resulted in their staying home and their problems parenting their toddler.

We have shown that ovarian volume in women aged from 25 to 51, as measured by tranvaginal ultrasound, may be used to estimate accurately how many follicles (eggs) are left and therefore what is ...New research shows that the seasons may be involved in onset of menopause

This is reflected in a strong genetic correlation between the traits, and there is evidence that ecdysone is the mechanism for this connection: high levels of ecdysone result in large eyespots and fast development, while low lead to small eyespots and slow development.
