Back to Basics: Beyond Network Hygiene

In the past, Computer Network Defense (CND) intended to be minimally intrusive to the other requirements of IT development, business, and operations. This paper outlines how different security paradigms have failed to become effective defense approaches, and what the root cause of the current situation is. Based on these observations, a different point of view is proposed: acknowledging the inh...

Looking back in time beyond the big bang

String theory can (in principle) describe gravity at all curvature scales, and can be applied to cosmology to look back in time beyond the Planck epoch. The duality symmetries of string theory suggest a cosmological picture in which the imprint of a primordial, pre-big bang phase could still be accessible to present observations. The predictive power of such a scenario relies, however, on our a...

Back to the Future: Moving Beyond “Mesenchymal Stem Cells”

The last decade was dominated by dissemination of the notion that postnatal "mesenchymal stem cells," found primarily in bone marrow but also in other tissues, can generate multiple skeletal and nonskeletal tissues, and thus can be exploited to regenerate a broad range of tissues and organs. The concept of "mesenchymal stem cells" and its applicative implications represent a significant departu...

When is meconium stained liquor actually bile stained vomit?

Three babies said to have had 'meconium stained liquor' were subsequently found never to have passed meconium. The green discoloured liquor was the result of bilious vomiting in utero secondary to intestinal obstruction.
