Sets & the city: World Science Festival 2012, New York-style (Part 1 of 2)

(Âé¶¹ÒùÔº) -- New York City is the nexus of all things intellectual, cultural and academic. (Being a native New Yorker, I admit being somewhat biased.) Either way, one highlight in this complex and vibrant metropolis is the ...

Solving energy problems, one molecule at a time

Jeffrey Grossman says Cambridge has a better climate than California — for carrying out materials science research, that is. That’s why Grossman decided, two years ago, to make the move from the University of California ...

Âé¶¹ÒùÔºicists uncover new data on adenine, a crucial building block of life

Early Earth's atmosphere provided little shielding for ultraviolet light from space, so many prebiotic molecules, bombarded by it and light of other wavelengths, had a hard time surviving at all. But some molecules became ...
