Vibrational spectroscopy technique enables nanoscale mapping of molecular orientation at surfaces

Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at ...

Enceladus plumes may hold a clear clue to ocean habitability

How can scientists estimate the pH level of Enceladus' subsurface ocean without landing on its surface? This is what a study ...

The race to build a super-large ground telescope is likely down to two competitors

I have been writing about the Giant Magellan Telescope for a long time. Nearly two decades ago, for example, I wrote that ...
