00:46 2D metals made using sapphire pressTaking inspiration from industrial forging, researchers have demonstrated a way to squeeze molten metals into atomically-thin layers, creating relatively large flakes of 2D metals. Using a hydraulic press containing two sapphire anvils, a team was able to create sub-nanometer thick sheets of different metals — these sheets had diameters exceeding 0.1 mm, orders of magnitude larger than other methods have achieved. 2D metals have been theorized to possess several useful properties not seen in their larger, 3D counterparts, but have been difficult to make at scale, something this method may help overcome.Research Article: Zhao et al.News and Views: Metals squeezed to thickness of just two atoms09:36 Research HighlightsThe discovery of ancient puppets on remains of a large pyramid offers a glimpse into rituals in Mesoamerica, and how the presence of a certain pattern of sleep brainwaves might help predict which people will recover from an unresponsive state.Research Highlight: Ancient puppets that smile or scowl hint at shared ritualsResearch Highlight: Who’s likely to wake up from a coma?
