Music enhances plant growth and keeps pests at bay
A recent AoB blog caught my eye (ear?). Do plants respond to music? The blog refers to an experiment in which plants were assembled in Cadogan Hall, London for a 3-hour recital performed by the UK’s Royal Philharmonic Orchestra to investigate the effects of music on plant growth. Knowing that CAB Abstracts is a good…
Generating energy from sewage will soon become a reality in the north of England
Being a wastewater treatment specialist, I have often pointed out that more projects should be making use of waste by-products to generate renewable energy. Anaerobic digestion (AD) processes, which are widely used in wastewater treatment processes produce biogases. These are mainly methane and carbon dioxide gases, which are often wasted. In a recent paper McCarty…
He’s OK if you don’t get on the wrong side of him
Most of us have preferences such as left- or right-handedness, and tend to favour one eye over another to look down a telescope. These biases are the result of brain lateralisation, with a dominant left side of the brain leading to right handedness, and vice versa. Many animals show comparable biases. Lesley Rogers believes a…

She was barefoot and limping. Flies dotted her face, craving the moisture of her eyes, lips,…

Some moths…
How green is bioenergy?
It is well known that there is an international effort to replace fossil energy with biomass in an effort to reduce greenhouse gas (GHG) emissions and curb global warming. It was widely assumed that biomass combustion would be inherently 'carbon neutral' because it only releases carbon taken from the atmosphere during plant growth. However, there…
If I ruled the world…
On the way home yesterday I was musing about the UN summit on non-communicable diseases (NCDs) happening next week. If I was in charge what would I do? As we are dealing with limited resources in many countries, prevention could achieve more than concentrating on cure. What I’d do about NCDs would be to ban…
