British scientist Ian Wilmut, whose research was central to the creation of the cloned animal, Dolly the Sheep, has died at the age of 79, the University of Edinburgh said on Monday.
His death on Sunday years after being diagnosed with Parkinson’s disease, was announced by the University of Edinburgh, where he worked, Reuters said.
Wilmut, along with Keith Campbell from the animal sciences research institute in Scotland, generated news headlines and heated ethical debates in 1996 when they created Dolly, the first mammal to be cloned from an adult cell.
"He led efforts to develop cloning, or nuclear transfer, techniques that could be used to make genetically modified sheep. It was these efforts which led to the births of Megan and Morag in 1995 and Dolly in 1996," the university said in a statement.
Dolly, named after country singer Dolly Parton, was the first mammal to be cloned from an adult cell, using a process called somatic cell nuclear transfer (SCNT).
This involved taking a sheep egg, removing its DNA and replacing it with DNA from a frozen udder cell of a sheep that died years before. The egg was then zapped with electricity to make it grow like a fertilized embryo. No sperm were involved.
Dolly’s creation triggered fears of human reproductive cloning, or producing genetic copies of living or dead people, but mainstream scientists have ruled this out as far too dangerous.
Wilmut, who was born near Stratford-upon-Avon, attended the University of Nottingham, initially to study agriculture, before switching to animal science.
He moved to the University of Edinburgh in 2005, received a knighthood in 2008 and retired from the university in 2012.

One of the Amazon River's main tributaries has dropped to its lowest level ever recorded, Brazil's geological service said Friday, reflecting a severe drought that has devastated the Amazon rainforest and other parts of the country.

The level of the Negro River at the port of Manaus was at 12.66 meters on Friday, as compared with a normal level of about 21 meters. It is the lowest since measurements started 122 years ago.

The previous record low level was recorded last year, but toward the end of October.

The Negro River's water level might drop even more in coming weeks based on forecasts for low rainfall in upstream regions, according to the geological service's predictions.

Andre Martinelli, the agency's hydrology manager in Manaus, was quoted as saying the river was expected to continue receding until the end of the month.

Water levels in Brazil's Amazon always rise and fall with its rainy and dry seasons, but the dry portion of this year has been much worse than usual.

All of the major rivers in the Amazon basin are at critical levels, including the Madeira River, the Amazon River's longest tributary.

The Negro River drains about 10% of the Amazon basin and is the world's sixth-largest by water volume. Manaus, the biggest city in the rainforest, is where the Negro joins the Amazon River.

For locals, the drought has made basic daily activities impossible. Gracita Barbosa, 28, works as a cashier on a floating shop on the Negro River.

She's out of work because boats that once stopped there can no longer navigate the river due to the low water levels.

Barbosa can no longer bathe in the river and now has to travel longer distances to collect drinking water.
