I suppose looking at it in terms of the great lofty visions of transhumanism — longer healthy lifespans, better brains, intelligent machines, cyborg body parts, genomic evolutions and so forth – what once were dreams and small projects are now dreams and well-funded projects and even companies that hope to bring products to market. This means that there has been enough incremental scientific and technological progress to bring it to the point where investors, scientists, engineers and so on are taking this stuff seriously.Ecologists Say Metabolism Accounts for Why Natural Selection Favors Only Some Species
"Organisms whose designs fit the physiological window have been favored by natural selection across all of life's major kingdoms," he said. "This observed, narrow range might therefore be considered as the preferred, optimal range for the functioning of living matter as a whole." - "Species had to invent diverse tricks to remain near the metabolic optimum, from which the progressive evolutionary increase in body size – from prokaryotes to largest vertebrates and plants – was continually taking them away," Li said.Self-propelled microbots navigate through blood vessels
Researchers at the École Polytechnique de Montréal, in Canada, led by professor of computer engineering Sylvain Martel, have coupled live, swimming bacteria to microscopic beads to develop a self-propelling device, dubbed a nanobot. While other scientists have previously attached bacteria to microscopic particles to take advantage of their natural propelling motion, Martel's team is the first to show that such hybrids can be steered through the body using magnetic resonance imaging (MRI).
