How likely is it that biological agents will be used deliberately to cause widespread harm?

D uring the past few years, there has been substantial debate concerning the risks and benefits of certain experiments with pathogens—initially motivated by two publications in 2012 that described laboratory efforts to enhance the mammalian transmissibility of the avian H5N1 influenza virus. One of these two reports was particularly noteworthy because the experiments were designed to yield new ...

Livable Housing Design – Is It Likely to Work?

The lack for accessible housing in Australia has contributed to the marginalisation and exclusion of people with disability, older people and their families (Saugeres, 2010). It has also resulted in significant cost to the community, through an over-reliance on support services and specialist accommodation, and responses to avoidable home-based injuries (Ozanne-Smith, Guy, Kelly & Clapperton, 2...

Proteus--is it a likely aetiological factor in chronic polyarthritis?

RNA catalysis--is that it?

Ribozymes are RNA molecules that accelerate chemical reactions, enzymes that happen to be made of RNA rather than protein. Aside from the chemical challenge of trying to explain how a nucleic acid can do that, why should anyone care? Although these species created a lot of interest when the RNA journal began 20 years ago, they have slipped out of fashion more recently, and some may think RNA ca...

Why Believe That There Is a God?

This article presents an argument for the existence of God, showing that the evident phenomena are best explained by supposing that a God causes them. The argument is based on the inductive force of four very evident general phenomena: that there is a physical Universe; that it is governed by very simple natural laws; that those laws are such as to lead to the existence of human bodies; and tha...
