A new study into the Earth beneath our feet has discovered that an ancient ocean floor structure could be wrapped around the planet's core which could be taller that Mount Everest in some areas. A brand new high-resolution mapping of the core has uncovered things that scientists previously didn't know according to a study that was first published in April. The discovery found that a thin but dense layer sits at around 2,900 kilometers below the surface at the Core Mantle Boundary where rocks meet the molten outer core of the planet. Geologist Samantha Hansen from the University of Alabama is quoted in the study saying: "Seismic investigations, such as ours, provide the highest resolution imaging of the interior structure of our planet, and we are finding that this structure is vastly more complicated than once thought." She adds: "Our research provides important connections between shallow and deep Earth structure and the overall processes driving our planet.” Hansen and her team conducted the research from 15 different stations in Antarctica by using seismic waves created by Earthquakes to create a map of what the inside of the planet looks like. The team identified the unexpected energy within seconds of the boundary-reflected wave from the seismic data. The findings show that although the layer is very thin it does spread for many, many kilometers and has been called the ultra-low velocity zone (ULVZs) due to its strong wave speed reductions. Due to the properties of the ULVZs the experts believe that the layer could vary dramatically in height. Geophysicist Edward Garnero from Arizona State University adds: "The material's thickness varies from a few kilometers to [tens] of kilometers. This suggests we are seeing mountains on the core, in some places up to five times taller than Mt. Everest." These underground mountains could play a significant role in how heat escapes from the Earth's core and power magnetic fields and volcanic eruptions. The team's studies suggest that the layer could encase all of the core but further research will have to be carried out to determine if that is the case.

The emphasis on a good night's sleep is nothing new. But now, neuroscientist, Dr Andrew Huberman, has shared one routine that he suggested can make you "better at everything." In a YouTube talk on After Skool, Dr Huberman said he immediately starts his day with a sunrise walk at 6.30am. "Getting outside for a 10-minute walk or a 15-minute walk is absolutely vital to mental and physical health," he shared. Despite coffee being the get-up-and-go drink for most, Huberman says the first beverage he consumes is salty water, as he claims it helps improve bodily functions. "There are certain foundational behaviours - certain dos and don'ts that set the stage for you to be better at everything," he continued. "It always comes back to two elements - that's sleep and what I call non-sleep deep rest. Sleep is the fundamental practice or part of our 24-hour cycle where if you don't get it on a consistent basis, you are down-regulating your ability to do everything." He went on to discuss a "90-minute bout of work," in which he says he turns his phone off to fully optimise this time. "You'd be amazed how much you can get done in 90 minutes if you are focused," he said. Huberman then ensures he gets in an hour's worth of exercise before exposing himself to cold temperatures such as an ice bath. The NHS states that there are no official guidelines regarding how much sleep a person should get each night as everyone is different. "On average, a 'normal' amount of sleep for an adult is considered to be around seven to nine hours a night. Children and babies may sleep for much longer than this, whereas older adults may sleep less," they wrote. Sign up for our free Indy100 weekly newsletter Have your say in our news democracy.
