 There is still disquiet about the impact of physical funds,especially in copper. "We're nervous about an ETF in copper.Copper actually is supply constrained so you could conceivablycreate problems in the real world by hoarding copper," said DougHepworth, executive vice president at Gresham InvestmentManagement in New York.

To manipulate the foreign DNA, the scientists used optical tweezers, which essentially tweaks a laser beam whose electromagnetic field can grab hold of and transport a plasmid-coated particle. The researchers first moved the particle to the surface of the cell membrane. Guided by the trapped particle, they then created a tiny pore in the cell membrane using an ultra-short laser pulse from a femtosecond laser. While another laser beam detected the exact location of the cell membrane, they pushed the particle through the pore with the tweezers. Using this technique, the scientists were able to ease a microparticle right up to the pore in the membrane and drop it into the cell, like a golfer sinking an easy putt.
