A stark new discovery has revealed that cannibalism was a common practice in Europe to commemorate the dead 15,000 years ago. Research from London’s Natural History Museum (NHM) found human remains at a famed Paleolithic site in Cheddar Gorge that appeared to have bite marks across 100 of the bones. Scientists believe this is sufficient evidence of cannibalism in the Magdalenian group. "We interpret the archaeological evidence that cannibalism was practised on multiple occasions across northwest Europe over a short period of time as an indication that such behaviour was part of a funerary behaviour among Magdalenian groups, and not simply practised out of necessity," Dr Silvia Bello, paleoanthropologist and principal researcher said in a statement. Postdoctoral researcher William Marsh went on to say that the study contextualised the area by reviewing all sites "attributed to the Magdalenian culture." "During the terminal time period of the Palaeolithic, you actually see a turnover in both genetic ancestry and funerary behaviour, indicative of population replacement as Epigravettian groups migrated northwards," he said, as per IFL Science. "We believe that the change in funerary behaviour identified here is an example of demic diffusion where essentially one population comes in and replaces another population and that brings about a change in behaviour." Fast forward to 2023, and now people are having their bodies frozen in hopes they can "wake up" in the future. Cryonics "is the practice of preserving humans and animals at cryogenic temperatures in the hope that future science can restore them to a healthy living condition as well as rejuvenate them," according to the National Library of Medicine. "At present cryonics can only be performed after pronouncement of legal death of the cryonics subject." Sign up for our free Indy100 weekly newsletter Have your say in our news democracy.

Researchers funded by the US Air Force are developing a new type of device that can invite comparisons to a weapon used by a Batman villain. Scientists, including Patrick Hopkins from the University of Virginia in the US, are working on a new device to be used for on-demand surface cooling for electronics inside spacecraft and high-altitude jets. The device may seem similar to the freeze gun used by Batman villain Mr Freeze to “ice” his enemies. “A lot of electronics on board heat up, but they have no way to cool down,” said Dr Hopkins, whose lab has been granted $750,000 over three years to develop the technology. On Earth, electronics in military craft can rely on nature to cool themselves, but in space, this may be a challenge, scientists said. Citing an example, researchers said the Navy uses ocean water in its liquid cooling systems while flying jets can rely on air that is dense enough to help keep components chilled. “With the Air Force and Space Force, you’re in space, which is a vacuum, or you’re in the upper atmosphere, where there’s very little air that can cool,” Dr Hopkins said. “So what happens is your electronics keep getting hotter and hotter and hotter. And you can’t bring a payload of coolant onboard because that’s going to increase the weight, and you lose efficiency,” he explained. In such extra-terrestrial environments, a jet of plasma, the fourth and most common state of matter in the universe, can be used in the interior of a craft. “This plasma jet is like a laser beam; it’s like a lightning bolt. It can be extremely localized,” Dr Hopkins explained. One of the strange qualities of plasma is that while it can reach temperatures as hot as the surface of the Sun, it chills before heating when it strikes a surface. In the new research, published recently in the journal ACS Nano, scientists fired a purple jet of plasma generated from helium through a hollow needle encased in ceramic, targeting a gold-plated surface. When researchers turned on the plasma, they could measure temperature immediately at the point where the plasma hit, and could see that the surface cooled first and then heated up. “We were just puzzled at some level about why this was happening, because it kept happening over and over,” Dr Hopkins said. “And there was no information for us to pull from because no prior literature has been able to measure the temperature change with the precision that we have. No one’s been able to do it so quickly,” he said. The strange surface-cooling phenomenon, according to scientists, was the result of blasting an ultra-thin, hard-to-see surface layer, composed of carbon and water molecules. Researchers compare this to a similar process that happens when cool water evaporates off of our skin after a swim. “Evaporation of water molecules on the body requires energy; it takes energy from body, and that’s why you feel cold. In this case, the plasma rips off the absorbed species, energy is released, and that’s what cools,” the researchers explained. Using the method, scientists could reduce the temperature of the setup by several degrees for a few microseconds. While this may not be dramatic, they said it is enough to make a difference in some electronic devices. Now, thanks to the Air Force grant, researchers are looking at how variations on their original design might improve the apparatus. “Since the plasma is composed of a variety of different particles, changing the type of gas used will allow us to see how each one of these particles impact material properties,” researchers said.

Scientists have claimed to make a breakthrough that would be “one of the holy grails of modern physics” – but experts have urged caution about the results. In recent days, many commentators have become excited by two papers that claim to document the production of a new superconductor that works at room temperature and ambient pressure. Scientists in Korea said they had synthesised a new material called LK-99 that would represent one of the biggest physics breakthroughs of recent decades. Superconductors are a special kind of material where electrical resistance vanishes, and which throw out magnetic fields. They are widely useful, including in the production of powerful magnets and in reducing the amount of energy lost as it moves through circuits. They are also often impractical, since they require low temperatures and high pressure. That means that they cannot be used in most traditional circuits, for instance. Since the beginning of the last century, scientists have been working not only to understand superconductivity but also develop new materials that would allow the phenomenon to be harvested at ambient temperatures and pressures. That has not been successful, and the discovery of such a material would mark a major breakthrough in physics. The new papers, published in recent days as a preprint on the website arXiv, claims to have overcome that problem. The researchers said they had not only found a way to synthesise such a superconducting material, but also that it could be done relatively easily – leading to huge excitement on social media. One Twitter thread from Alex Kaplan, a recent Princeton graduate who is now head of coffee product at startup Cometeer, helped propel the news into the mainstream. His thread had been viewed 8.5 million times, Twitter said, and has been retweeted more than 10,000 times. “Today might have seen the biggest physics discovery of my lifetime. I don’t think people fully grasp the implications of an ambient temperature / pressure superconductor,” he wrote in a long thread that went on to explain the possible applications of the material. Mr Kaplan pointed to the fact that vast amounts of energy are lost in the transmission of electricity across the world, that the the authors claimed material could be made in just 34 hours with simple equipment, and that such a superconductor would have revolutionary uses in everything from nuclear fusion reactors to batteries and quantum computers. Scientists away from the work agreed that such a breakthrough would be hugely significant. But they urged caution, pointing to the fact that the paper has not yet gone through the peer review process, the results have not been replicated, and that there could be other explanations for the apparently astonishing behaviour described in the work. “A real, working room-temperature superconductor which works at ambient pressure would be one of the holy grails of modern physics, unlocking major new developments in energy, transportation, healthcare, and communications,” said Mohammad Yazdani-Asrami of the University of Glasgow’s James Watt School of Engineering. “As it stands, however, the paper is not yet peer-reviewed and has not yet been tested in other labs to see if other researchers can reproduce its results. These are both key to determining for sure whether the world should be getting excited about the authors’ claims, which need much more scrutiny at this early stage. If the claims of findings are approved, perhaps, this is one of the most significant achievements of last few decades in physics and material engineering.” Others voiced specific concerns about the paper. Some of the results meant that other researchers working on superconductors were not convinced by the claims made in the paper. “The recent preprint by Lee, Kim and Kwon suggesting that they have observed room temperature superconductivity in the copper doped lead phosphate system, without the need for very high applied pressures, is interesting, but not yet wholly convincing,” said Susannah Speller, Professor of Materials Science at the University of Oxford, and Chris Grovenor, Professor of Materials at the University of Oxford. Professors Speller and Grovenor pointed to the fact that the data did not show the behaviour that would be expected to happen when the material became superconducting. Features that would be expected to be evident in the results were not, they said, and “and so it is too early to say that we have been presented with compelling evidence for superconductivity in these samples”. John Durrell, professor of superconductor engineering at Cambridge University, said that it could take considerable time to see the practical benefits of the breakthrough, even if the team’s results were confirmed. “There will be understandable scepticism about this result in the community as there have been numerous reports of room temperature superconductors over the years which have not held up,” he told The Independent. “I would, therefore, personally withhold judgement on this work until it becomes clear if the result is reproducible in other laboratories. “From my engineering point of view, a practical room temperature superconductor would be potentially transformative – allowing a host of exciting applications such as cheap MRI machines, more compact and efficient motors and low loss power transmission. “However, there can be significant challenges in turning a newly discovered superconducting material into a practical material. In previous cases, this has taken one or two decades and is not always possible.” Read More Europe to cover continent in fast EV chargers under new law Elon Musk takes control of @X account from user who had held it for 16 years iPhone users urged to check their photo library amid fears they could be deleted Europe to cover continent in fast EV chargers under new law Elon Musk takes control of @X account from user who had held it for 16 years iPhone users urged to check their photo library amid fears they could be deleted
