Could there be life below Saturn’s moon Enceladus and Jupiter’s moon Europa?

April 16, 2017

During Cassini’s deepest dive through the plume of Saturnian moon Enceladus, Southwest Research Institute scientists discovered hydrogen gas in the erupting material in the plume. This discovery provides further evidence for hydrothermal activity (illustrated here) and heightens the possibility that the ocean of Enceladus could have conditions suitable for microbial life.

How to condense water out of air using only sunlight for energy

MIT-UC Berkeley invention may offer hope for the two-thirds of the world’s population experiencing water shortages, including the one third living in desert climates

Nanopores map small changes in DNA for early cancer detection

April 12, 2017

Nanopore cancer detection. To detect DNA methylation changes (for cancer early warning), researchers punched a tiny hole (pore) in a flat sheet of graphene (or other  2D material). They then submerged the material in a salt solution and applied an electrical voltage to force the DNA molecule through the pore. A dip in the ionic current (black A) identified a methyl group is passing through, but a dip in the electrical current (blue A) could detect smaller DNA changes.
