Most liquids are in suspension. Particles too small to see by naked eye swirl everywhere as gravity and temperature changes move them around. Keeping liquids from separating can be a hassle for the foods we buy in the supermarket, but also for the pharmaceutical industry seeking to extend the shelf life of medicine as long […]

Our world is losing ice at record rate
A research team – the first to carry out a survey of global ice loss using satellite data – has discovered that the rate at which ice is disappearing across the planet is speeding up. The findings also reveal that 28 trillion tonnes of ice was lost between 1994 and 2017 – equivalent to a […]

Iodine thruster could slow space junk accumulation
For the first time ever, a telecommunications satellite has used an iodine propellant to change its orbit around Earth. The small but potentially disruptive innovation could help to clear the skies of space junk, by enabling tiny satellites to self-destruct cheaply and easily at the end of their missions, by steering themselves into the atmosphere […]

Lake heatwaves to increase due to climate change
Lake heatwaves – periods of extreme warm surface water temperature in lakes – may become hotter and longer by the end of the 21st century, according to a new study published in Nature, increasing the link between climate change and extreme events. To source
Genesis of blue lightning into the stratosphere detected from the International Space Station
Dark clouds, the smell of rain on a hot sidewalk, the flashes of intense light followed by a loud crackling and then a low, rolling thunder – who doesn’t love a good summer thunderstorm? We’ve all seen one, heard one, or been completely soaked by one. But how much do we really know about this […]

Keep this surface dirty
Image: A ‘do not touch’ directive applies to both a Matisse painting and this Matiss experiment on board the International Space Station. Designed to test the antibacterial properties of hydrophobic (or water-repelling) surfaces on the Station, the sample holders of the upgraded Matiss-2.5 experiment have done their work for roughly a year on board and […]
