1,3-Glucan: Silver Bullet or Hot Air?

-Glucans belong to a group of biologically active natural compounds called biological response modifiers. These substances represent highly conserved structural components of cell walls in yeast, fungi, grain and seaweed. The effects of -glucan on immune reactions are well established however direct comparisons of the biological activities of several individual glucans are extremely rare. As th...

Modern Management: Good for the Environment or Just Hot Air?*

We use an innovative methodology to measure management practices in over 300 manufacturing firms in the UK. We then match this management data to production and energy usage information for establishments owned by these firms. We find that establishments in better managed firms are significantly less energy intensive. This effect is quantitatively substantial: going from the 25th to the 75th pe...

Helium: impending crisis for radiology, or just more hot air?

It is one of the most ubiquitous elements in the universe, second only to hydrogen. Balloons filled with it are almost everywhere and can be purchased for only a few dollars. One can easily be forgiven for assuming that helium, which plays a currently irreplaceable role in the superconducting magnets used in MRI and particle accelerators, is not only relatively easily obtained but in inexhausti...

Hot topic or hot air? Climate change and malaria resurgence in East African highlands.

Climate has a significant impact on malaria incidence and we have predicted that forecast climate changes might cause some modifications to the present global distribution of malaria close to its present boundaries. However, it is quite another matter to attribute recent resurgences of malaria in the highlands of East Africa to climate change. Analyses of malaria time-series at such sites have ...
