Inside the 8,000-year-old city at the bottom of the English channel
Inside the 8,000-year-old city at the bottom of the English channel
Ever wondered what’s hiding at the bottom of the English Channel? Deep sea divers do – partly because the cold waters and strong tides make it a notoriously difficult place to explore. One relic down there that few people have seen is the remains of an 8,000-year-old civilisation in an area called Doggerland – the landmass that once connected the British Isles to Europe. A National Geographic team led by scientist Albert Lin went down there in 2019 to find the so-called "lost city". The first thing they found were the remains of a tree, which had survived underwater for more than 8,000 years. As the divers went deeper, they came across a wooden structure that Lin thought could be a dock. “It feels like we are sitting in an ancient ghost town, but underwater,” he said. The existence of Doggerland was first confirmed in the late 19th century, but it wasn’t until about 100 years ago that ships started accidentally unearthing items of archaeological importance. In 1931, a trawler hauled up a lump of peat while fishing about 25 miles east of Norfolk. It contained an antler point, which was possibly used as a spear, dating from between 10,000BC and 4,000BC. Back on the surface, Lin described the wooden structure as “a whole platform down there. It's layered, one piece on top of the other, almost like a dock”. He added:” It’s cold down there and murky. But it's incredible. “You know, you descend down this line and out of the darkness comes the ancient past.” The wood survived because it was so deprived of oxygen, according to maritime archaeologist Garry Momber. “It's just preserved in a sort of anaerobic, oxygen-free environment. It would have stayed there for many more thousands of years. “But recently, the old landscape’s eroding away, which is how we found this.” The maritime archaeologist said finding composite structures like this was of 'international significance'. “It's 8,000 years old,” Momber added. “You don't just get these everyday.” Sign up for our free Indy100 weekly newsletter How to join the indy100's free WhatsApp channel Have your say in our news democracy.

Odd ‘demon’ particle found inside superconductor may help demystify ‘holy grail’ of physics
Odd ‘demon’ particle found inside superconductor may help demystify ‘holy grail’ of physics
Scientists have finally found a “demon” subatomic particle that was predicted to exist nearly seven decades ago and speculated to play an important role in the behaviours of a range of metals and alloys, including superconductors. Physcist David Pines in 1956 theorised that electrons, which normally have a mass and negative electric charge, can under some conditions combine to form a composite “demon” particle that is massless, neutral and does not interact with light. These theorised interesting properties, however, made these particles elude detection – until now. After a nearly 70-year search for these subatomic entities, researchers, including those from the University of Illinois Urbana-Champaign, have finally found signatures of Dr Pines’ “demon” particles in the metal strontium ruthenate. “Demons have been theoretically conjectured for a long time, but experimentalists never studied them. In fact, we weren’t even looking for it. But it turned out we were doing exactly the right thing, and we found it,” study co-author Peter Abbamonte said. Electrons – which are distributed in different energy bands within atoms – are known to lose their individuality in solids with electric interactions making the particles combine to form collective units. With some threshold energy, studies have also shown electrons can form composite particles called plasmons with a new charge and mass. However, the mass is so large that these plasmon particles cannot form with the kind of energies available at room temperature. Revelations on room-temperature semiconductors are considered to be one of the “holy grails” of physics. But Dr Pines theorised that if a solid has electrons in more than one energy band, as many metals do, their respective plasmons may combine in an out-of-phase pattern to form a new plasmon that is massless and neutral – a demon. Since these special particles are massless, he argued they can form with any energy and may exist at all temperatures – leading to speculation that the demons have important effects on the behaviour of some metals with multiple energy bands. “The vast majority of experiments are done with light and measure optical properties, but being electrically neutral means that demons don’t interact with light,” Dr Abbamonte explained. So a completely new experiment was needed to detect them. In the research, scientists were studying the compound strontium ruthenate as it is similar to high-temperature superconductors – a special kind of material where electrical resistance vanishes. For a survey of the metal’s electronic properties, they synthesised high-quality samples of the metal. They then applied a technique to study the metal that uses energy from electrons shot into the metal to directly observe the metal’s features, including plasmons that form. During their observation of the electron interactions, scientists found something unusual – an electronic mode with no mass. “At first, we had no idea what it was. Demons are not in the mainstream. The possibility came up early on, and we basically laughed it off. But, as we started ruling things out, we started to suspect that we had really found the demon,” Ali Husain, another author of the study, said. Researchers then sought to calculate how electrons are distributed across bands inside strontium ruthenate. Predictions by Dr Pines indicate there are specific conditions when “demons” are likely to form, and it remained unknown whether strontium ruthenate would have the particle. “We had to perform a microscopic calculation to clarify what was going on. When we did this, we found a particle consisting of two electron bands oscillating out-of-phase with nearly equal magnitude, just like Pines described,” found Edwin Huang, another author of the study. “Our study confirms a 67-year-old prediction and indicates that demons may be a pervasive feature of multiband metals,” scientists wrote in the study.
