Senescent cells that express the cell cycle inhibitory protein p16INK4A have been found to actively drive naturally occurring age-related tissue deterioration3,4 and contribute to several diseases associated with ageing, including atherosclerosis5 and osteoarthritis6.
Furthermore, children with conduct problems are at risk of being rejected and disliked by peer students as early as preschool and have been found to actively seek peers who are behaviorally similar to themselves [ 8].
Plants have been observed to demonstrate root segregation (Schenk et al. 1999) which makes sense from this perspective; however in different contexts they have been found to actively proliferate into areas of competition (Hodge et al. 1999 c ; Robinson et al. 1999).
Next to light-shading, reduction of the coral's defensive potential and possible impairment of mucociliary feeding, epizoic acoelomorph flatworms have been found to actively compete with their coral host for zooplankton (Wijgerde et al., 2011b), which could reduce prey acquisition by the host.
It may be remarked that both Fermat and Maupertuis were guided by Aristotelian notions of economy in nature that have been found, if not actively misleading, too imprecise to retain a place in modern science.
Cells cultured under mild hypothermic conditions (30°C to 35°C) have been found to induce an actively regulated growth reduction in cells within the S or G1 phase of the cell cycle [ 23] and an increased rate of recombinant protein synthesis.
A large number of functional RNAs called small RNAs (sRNAs) have been found in bacteria which are not actively translated.
But it's in Turkey where the most child soldiers have been found, since 1994 the Kurdish separatists have been actively recruiting children into their ranks, going so far as to creating child-only regiments in the ongoing conflict with the Turkish government.
Methylobacterium species have been found in association with several species of plants, actively colonizing leaves, stem, branches and roots [ 54– 60].
Only actively cellulolytic rumen species have been found to cause extensive solubilisation of plant cell wall material in pure culture.
