The oldest type of molecule in the universe has been located at last

digitaltrends.com – A milestone in the development of the early universe was the combination of helium and hydrogen atoms into a molecule called helium hydride. It would be expected that helium hydride would still be present in some parts of the universe. But strangely enough, it has never been detected in space before now.

Synthetic speech generated from brain recordings

sciencedaily.com – A state-of-the-art brain-machine interface created by neuroscientists can generate natural-sounding synthetic speech by using brain activity to control a virtual vocal tract -- an anatomically detailed computer simulation including the lips, jaw, tongue, and larynx. The study was conducted in research participants with intact speech, but the technology could one day restore the voices of people who have lost the ability to speak due to paralysis or neurological damage.

Scientists Observe Gravitational Instability in Which ‘Bubbles’ of Lighter Sand Form and Rise through Heavier Sand

sci-news.com – Gravitational (Rayleigh-Taylor, or R-T) instabilities are produced by the interactions of two fluids of different densities that do not mix -- oil and water, for example -- because the lighter fluid pushes aside the heavier one. Now, a team of researchers from Columbia University and ETH Zurich has observed an unexpected R-T-like instability in which lighter grains rise through heavier grains in the form of ‘fingers’ and ‘granular bubbles.’
