Archant © 2009 Scientists from the University of East Anglia have helped discover an active volcanic heat source beneath Antarctica’s fastest melting glacier. They are part of an international team to find that a volcanic heat source under the Pine Island Glacier plays an important role in its movement and melting. But the research team say climate change is still causing the bulk of glacial melt. Prof Karen Heywood, the expedition’s chief scientist, from UEA’s School of Environmental Sciences, said: “We measured a gas called helium in the water coming out of the cavity beneath a floating ice shelf. This gas comes from the earth’s mantle, where there are active volcanoes under the Antarctic ice sheet. The discovery of volcanoes beneath the Antarctic ice sheet means there is an additional source of heat to melt the ice, lubricate its passage towards the sea, and adding to the melting from warm ocean waters. … [Read more...] about UEA scientists in Antarctica volcanic heat discovery

Picture: Google Archant A shop owner has slammed telecoms companies after being left without broadband and a working phone line for almost a month despite promises the problem would be fixed within a couple of days. Andrew Shepherd, of St Aubyn’s Road in Lowestoft, said his street along with St Peter’s Road, Carlton Road, Lorne Road, and Richmond Place had all been left without any service, with more believed to be affected. Mr Shepherd, who runs Parrs in London Road South, said his home phone line had initially stopped working on Wednesday, May 30, before engineers said the problem would be fixed within two days on Thursday, May 31. On Monday, July 4, the repair work was pushed further back with Mr Shepherd told it would not be solved until the end of the week, before it was once again delayed at the end of that week to … [Read more...] about Broadband and phone line outage described as “intolerable” by business owner

PUBLISHED: 11:35 13 June 2018 | UPDATED: 12:31 13 June 2018 Jessica Frank-Keyes The Tacolneston Transmitter Archant Freeview viewers across Norfolk have described their loss of signal as ‘very annoying’ after being asked to retune their TVs. Users of the TV service were told to retune their sets last week to make sure they kept receiving a full set of channels. But some people have been experiencing problems after the engineering works were carried out on the main transmitter at Tacolneston, near Long Stratton. Lorraine Smith, from Honing, said: “Can’t get any BBC channels. “Rang Freeview and they sent someone out and they told me I need a new aerial. “Well I didn’t have any problems before so does that mean everyone now needs a new aerial now they’ve done whatever they have done?” Ann Eccleston, from Weybourne, added: “Can’t get channels one, two or three in Weybourne and keep losing five. “It’s … [Read more...] about Freeview viewers in Norfolk describe signal loss as ‘very annoying’

DNA takes the form of a double helix but researchers at the UEA have discovered a way to change it.. jm1366 The shape of DNA can be changed with a range of triggers including copper and oxygen according to research from the University of East Anglia. UEA - University of East Anglia. Picture: ANTONY KELLY The structure of DNA is widely accepted to exist as a double helix, but different DNA structures can also be made. It was previously known that DNA could be changed using acid, which causes it to fold up. This can be used as a switch for on and off in DNA nano-machines and using copper salts will cause DNA to change into a hairpin shape. Her new findings show that other triggers, including oxygen and a substance similar to Vitamin C, can also change its shape. Lead researcher Dr Zoe Waller from UEA’s School of Pharmacy said: “The potential changes in shape can be used as on/off switches for logic gates in DNA computing. Our findings could also be used in nanotechnology, … [Read more...] about UEA discovers DNA can be changed with oxygen
