Methane-eating bacteria discovered beneath Antarctica

Published

Study: Beneath Antartica

METHANE-EATING bacteria discovered in a lake beneath Antarctica may prevent the powerful greenhouse gas from being release into the atmosphere as ice sheets melt, scientists believe.

Researchers from Aberystwyth University, Louisiana State University and Montana State University have analysed samples of water and sediment retrieved from Lake Whillans which lies 800 metres below the West Antarctic Ice Sheet.

Isolated from direct contact with the atmosphere for many thousands of years, the lake was successfully drilled by the Whillans Ice Stream Subglacial Access Research Drilling (WISSARD) project in 2013.

The team used a combination of measurements of methane concentrations and genomic analyses to describe how lake bacteria chemically convert methane in a way that reduces the warming potential of subglacial gases during ice sheet retreats.

The prevalence of methane-consuming bacteria in the upper lake sediment suggests a ‘methane bio-filter’ prevents the gas from entering the subglacial water, where it can eventually drain into the ocean and be released into the atmosphere.

The bacteria obtain energy from digesting the methane.

Their findings have been published in a paper in the journal Nature Geoscience – Microbial oxidation as a methane sink beneath the West Antarctic Ice Sheet.

Pupils at Ysgol Bro Pedr asked to self-isolate as COVID-19 case confirmed

Published

on

A SMALL number of pupils at Ysgol Bro Pedr, Lampeter have been asked to self-isolate for 14 days following the confirmation of a COVID-19 case at the school.

The Contact Group have been asked to self-isolate as a precautionary measure in the first instance. All confirmed contacts of the positive case must remain at home for 14 days to reduce the possible spread of the virus to family, friends and the wider community.

In addition, pupils travelling on the same bus as the confirmed positive case have also been contacted and asked to self-isolate for 14 days again as a precautionary measure in the first instance. These pupils come from more than one Year Group from Ysgol Bro Pedr.

Due to the strong procedures that have been put in place in the school, only a small amount of pupils are having to self-isolate. All parents have been contacted by the School.

The Council urges all parents to refer their children for a test if they develop any of the symptoms, which are:

  • a high temperature
  • a new continuous cough
  • a loss or change to sense of smell or taste.

Parents should also be aware of other symptoms early on, such as headaches, tiredness and general aches and pains usually associated with the flu.

You can apply for a test on https://gov.wales/apply-coronavirus-covid-19-test or by phoning 119.

No further details will be provided regarding this matter.
