Swarms of genetically modified mosquitoes could be released into the wild to combat dengue fever around the world.

Scientists are using sterile males to mate with infected females in the fight to curtail spread of disease that kills 25,000 people a year. A small-scale trial of the strategy, which was carried out in the Cayman Islands, had cut mosquito numbers by an impressive 80% in six months.

The World Health Organization estimates there are 50m cases of dengue fever a year. About 2.5 billion people are at risk, mostly in Africa and south-east Asia.

Pollution Paste
London Mayor, Boris Johnson, recently embarked on an ambitious plan to spray city streets with a pollution paste.

The "dust suppressant" acts as an adhesive to paste particulate matter to the streets instead of re-circulating in the air. Transport of London will spray the suppressant at two traffic-heavy spots over the next six months during the pilot phase. The city hopes the move will curb concentrations of particulate matter by 10 percent to 20 percent, similar to results from other pilot tests in Europe.

London is close to exceeding European Union limits for particulate matter, which complicates the respiratory systems of children and seniors.
