Observing Proteins And Cells In The Wild: "Quantum Dots" May Allow Researchers To Track Proteins And Cells In Their Natural Environments

Summary:
Imagine if molecular and cell biologists could watch proteins and cells at work in their natural habitat in the same way that wildlife biologists observe animals in the wild. They'd sit back and witness first hand their microscopic subjects' daily routines, interactions and movements, and the places they prefer to be. This fantasy is rapidly becoming a reality thanks to new Rockefeller University research that takes advantage of "quantum dot" technology.

Imagine if molecular and cell biologists could watch proteins and cells at work in their natural habitat in the same way that wildlife biologists observe animals in the wild. They'd sit back and witness first hand their microscopic subjects' daily routines, interactions and movements, and the places they prefer to be. This fantasy is rapidly becoming a reality thanks to new Rockefeller University research that takes advantage of a technology originally developed in the early 1980s for use in computers. Called "quantum dots," these fluorescent nanocrystals can be made to glow brightly in any desired color and thus for years have glimmered in the eyes of biologists hoping to use them for molecular and cellular imaging. But, while their potential has been clear, scientists have not been able to persuade living biological tissues to explicitly and safely take up the synthetic dots - until now.

Porsche CEO Says Supercar Is Not Dead: Cue the Spyder 918

TheStreet (Apr. 16, 2014) The Porsche Spyder 918 proves that, in an automotive world obsessed with fuel efficiency, the supercar is not dead. Porsche North America CEO Detlev von Platen attributes the brand's consistent sales growth -- 21% in 2013 -- with an investment in new technology and expanded performance dynamics. The hybrid Spyder 918 has 887 horsepower and 944 lb-ft of torque, but it can run 18 miles on just an electric charge. The $845,000 vehicle is not a consumer-targeted vehicle but a brand statement.
