That same train powered Mr. Bush's own justification for a pre-emptive strike against Saddam Hussein, down to his now-discredited argument that the Iraqi leader was developing unmanned aerial vehicles capable dropping biological weapons on American troops in the Mideast, or perhaps even the United States itself.
By that reasoning, any opposite-sex marriages couplings not capable of biological production of children should be barred.
Instead, developing microbes capable of biological inhibitor attenuation, which can occur concurrently with lignocellulose hydrolysis and biofuel production, would be an advantageous approach.
As a result, strains that are capable of biological vector transmission need not result in the more rapid development of AIDS.
Some unicellular cyanobacteria such as Cyanothece and Crocosphaera are also capable of biological N2-fixation (diazotrophic) [ 3], and play a significant role in marine nitrogen (N) cycle [ 4].
The work suggests that even "aged" DPM that has been suspended in the atmosphere for more than a decade is capable of biological activity, which has important public health implications given the abundance of this pollutant in the atmosphere.
In fact, no evidence exists to date that any retrovirus is capable of biological transmission by arthropods (Webb et al. 1989; Foil and Issel 1991; Kuno 2004; Kuno and Chang 2005).
Thus, in any reconstruction of the origin of life, the threshold should be mapped to the lowest possible point, i.e., to the minimally complex system capable of biological evolution.
Although conventional thought stipulates that fresh DPM must contain ultrafine organic PM, including polycyclic aromatic hydrocarbons and quinones, to be biologically active (Wichmann 2007), our data suggest that aged DPM is not inert but is capable of biological activity.
The emergence of smart materials and structures, smart sensors and actuators capable of mimicking biological transducers, bio-inspired signal-processing techniques, modeling and control of manipulators resembling biological limbs, and the shape control of flexible systems are the primary areas in which recent technological advances have taken place.
