Bejr Ronin Provides Alternate Pathway to Pristine Embryonic Stem Cells
Scientists have found a way to 鈥榮witch鈥?the structure of DNA using copper salts and EDTA (Ethylenediam yeezys inetetraacetic acid) 鈥?an agent commonly found in shampoo and other household produ nbbalance cts.It was previously known that the structure of a piece of DNA could be changed using acid, which causes it to fold up into what is known as an 鈥榠-motif鈥?But new research reveals that the structure can be switched a second time into a hair-pin structure using positively-charged copper (copper cations). This change can also be reversed using EDTA.The applications for this discovery include nanotechnology - where DNA is used to make tiny machines, and in DNA-based comput yeezy 700 ing 鈥?where computers are built from DNA rather than silicon.It could also be used for detecting the presence of copper cations, which are highly toxic to fish and other aquatic organisms, in water.Lead researcher Dr Zo毛 Waller, from UEA鈥檚 School of Pharmacy, said: 鈥淥ur research shows how the structure of our genetic material - DNA - can BOGOTA:Mudslides in southern Colombia have claimed at least 16 lives and injured some 65 people following recent torrential rains, the authorities said.Governor Sorrel Aroca of the Putumayo department called the development "an unprecedented tragedy," telling W Radio there were "hundreds of families we have n nb ot yet found, and whole neighborhoods missing."Strong quake of 6.9 magnitude hits Russia's far eastCarlos Ivan Marquez, director of the National Disaster Risk Management Unit adidas sneakers campus , told AFP that newbalance while "initially we are talking about 16 deaths," further fatalities were possible.The mudslides late Friday were caused by the rise of the Mocoa River and three tributaries, he said.Flash floods take dramatic toll in Lima and northern PeruPresident Juan Manuel Santos said he would travel to Mocoa, the Putumayo capital, to supervise rescue and assistance efforts in the heavily forested region.His presence would "guarantee attention to the victims of this tragedy, which has all Colombians in mour
