Staying awake at night…
What’s keeping us up at night? One of the largest longitudinal studies to date examined evening consumption of alcohol, caffeine and nicotine among an African-American cohort and objectively measured sleep outcomes in their natural environments instead of laboratory or observatory settings. The study involved 785 participants and totaled 5,164 days of concurrent actigraphy and daily […]
Kronus… Hot ice… Cold fire…
The spectacular planetary nebula NGC 7009, or the Saturn Nebula, emerges from the darkness like a series of oddly-shaped bubbles, lit up in glorious pinks and blues. This colourful image was captured by the MUSE instrument on ESO’s Very Large Telescope (VLT). The map – which reveals a wealth of intricate structures in the dust, […]
Transformations. Modern alchemy. Ancient secrets…
Since the Middle Ages, alchemists have sought to transmute elements, the most famous example being the long quest to turn lead into gold. Transmutation has been realized in modern times, but on a minute scale using a massive particle accelerator. Researchers have now taken a different approach to that alchemists’ ancient goal by making one […]
Iced water. With no ice. Alchemy. Summer breeze…
Water can remain liquid below zero degrees Celsius. It is called supercooled water and is present in refrigerators. At even smaller temperatures, supercooled water could exist as a cocktail of two distinct liquids. Unfortunately, the presence of ice often prevents us from observing this phenomenon. (1) Water has got super high surface tension and apparently, […]
Superconductivity. Intrinsic abilities. Alchemy. Being.
Scientists activated the intrinsic ability of graphene to superconduct (carry an electrical current with no resistance). Before that, superconductivity in graphene has only been achieved by doping it with, or by placing it on, a superconducting material – a process which can compromise some of its other properties. But in the study (published on January), […]
