Irish Water is due to begin repair works to a burst water main in the North East today.

A specially engineered section of pipe has been manufactured in Belfast - however the utility is warning it could be the weekend before supply is fully restored to 50,000 homes in Louth and Meath.

Once the pipe is installed it will be necessary to return the system to full pressure “very gradually” as there are fears the pipe may rupture again once the water is turned back on.

Irish Water has also warned that similar bursts may happen in other areas across the country due to ageing infrastructure.

It's claimed turning aluminium foil into a bio fuel catalyst could help tackle global waste and energy problems.

A researcher at Queen's University Belfast says he has developed a new technique to transform used tinfoil into an ingredient that can speed up the process of making green fuels.

Its unique thermal, chemical and mechanical stability means it can also be used as an absorbent, in electronic device fabrication or as an alternative for surgical material for implants.
