Horrifying ancient meal loved by Neanderthals is a dieter's dream – but would YOU eat sickening dish?
But the pungent delicacy was more than simply "starvation rations", said Melanie Beasley, assistant professor of anthropology at Purdue University, Indiana.

A number of Indigenous communities have viewed putrefied - or fermented - meat as highly desirable.
It is easier to digest, meaning the body can better and more quickly absorb nutrients without cooking.
Experts have long known that Neanderthals - our extinct human ancestor - were omnivores, eating meat and vegetables like most modern people.
But chemical signatures found in Neanderthal remains suggest they ate as much meat as lions.

Analysis of their bones found too much nitrogen than what a classic omnivore would have.
But hominins simply cannot tolerate eating the high levels of protein that large predators can.
When humans eat as much protein as Earth's apex predators – or hypercarnivores – over long periods of time, without consuming enough other nutrients they can develop protein poisoning.
Also known as "rabbit starvation", protein poisoning can lead to malnutrition and death.

Research from Beasley and her team suggests that Neanderthals had a hidden delicacy: maggots.
Similar to the historical diets of some indigenous communities, Neanderthals too may have dined on decaying meat.

"We found that stable nitrogen isotope values increase modestly as muscle tissue decomposes, ranging from -0.6 permil to 7.7 permil."
The researchers found that maggots found in dried, frozen or cached animal foods would have inflated the nitrogen levels in ancient humans during the Late Pleistocene era.

It is still unclear how many maggots an ancient human would need to eat to account for so much nitrogen.
More research is needed on changes in nitrogen-15 values of foods processed, stored and cooked following Indigenous traditional practices to "help us better understand the dietary practices of our ancient relatives," said Beasley.

Extinct creature found INSIDE ‘magical' Ancient Roman amulet lost for 2,000 years in ‘world first' discovery
A LONG extinct creature has been found inside a 2,000-year-old amulet that ancient Romans may have believed held magic powers, according to a new study. The mysterious marine creature, a trilobite, went extinct more than 250million years ago. 5 The fossil, now a common collector's item, showed clear signs of modifications that suggest it was made to be worn as a pendant or bracelet, according to researchers Credit: Archaeol Anthropol Sci (2025) 5 The small creatures would scavenge at the bottom of the ocean Credit: iStock - Getty It is the first time archaeologists have found a trilobite that was manipulated during Roman times, the Springer Nature journal. And it is only the third on record believed to have been deliberately collected by humans over a thousand years ago. The fossil, now a common collector's item, showed clear signs of modifications that suggest it was made to be worn as a pendant or bracelet, according to researchers. While the researchers did not find any holes or piercings in the fossil, they believe it was likely embedded in metal like gold or silver. READ MORE ON ARCHAEOLOGY Microscopic examination and high-contrast photographs of the fossil reveal human-made modifications, including seven artificial facets on the left and underside. These changes were used to flatten the fossil for use within a pendant or bracelet, the researchers said. 5 The fossil was found at the Roman settlement of A Cibdá de Armea in northwestern Spain Credit: Archaeol Anthropol Sci (2025) The fossil, found at the Roman settlement of A Cibdá de Armea in northwestern Spain, had been preserved in a natural cast mineralised with iron oxide , giving it a reddish hue. Trilobite fossils are frequently found in this way, and the colouring may have even made it appear more desirable as jewellery. Most read in Science After examining the weathering of the fossil, the researchers said the specimen was similar to fossils from the southern Central Iberian Zone, located approximately 430km from the discovery site. Weirdest fossil ever the 'Beelze-frog' was giant dog-sized toad that ate baby dinosaurs & had bite as strong as a Tiger The significant distance between the two places suggests ancient Romans intentionally transported these mysterious fossils for a purpose. The researchers say the interest from ancient Romans was possibly rooted in the belief that these specimens carried magical or protective powers. Trilobites are one of the earliest groups of arthropods to appear in the fossil record, and scuttled across ocean floors for almost 270million years. Among more than 22,000 species of trilobites, the researchers identified this ancient specimen as Colpocoryphe sp. It was unearthed alongside a bronze coin adorned with the face of Emperor Augustus, the first Roman Emperor who reigned from 27 BC until his death in 14 AD. According to the ancient historian Suetonius, Augustus was an avid collector of fossils. The Roman Emperor would import them from Greece, as well as personally excavate them on the island of Capri which had developed into a private resort. Augustus is credited with creating one of the first known paleontological museums at his villa, displaying the bones of long-lost creatures now understood to be fossils. 5 Among more than 22,000 species of trilobites, the researchers identified this ancient specimen as Colpocoryphe sp Credit: Archaeol Anthropol Sci (2025) 5 Trilobites are one of the earliest groups of arthropods to appear in the fossil record, and scuttled across ocean floors for almost 270million years Credit: SWNS:South West News Service A brief history of the Roman Empire Here's what you need to know...

Elon Musk's Neuralink brain chip lets paralysed woman write her name after 20 YEARS ‘just by thinking'
A PARALYSED woman has written her name for the first time in 20 years using only her mind. Audrey Crews is one of the participants in Elon Musk's Neuralink trial, having had a computer chip installed in her brain. 4 The telepathic powers were granted to Crews as part of the company's PRIME study, which aims to test BCI chips in human subjects Credit: X / @NeuraNova9 4 Once inserted in the participants' brain, the chip allows users to control digital interfaces through brain signals alone Credit: Getty The chip, or brain-computer interface (BCI) as Neuralink calls it, connects Crews' brain to a computer and allows her to control the mouse on the screen. Crews lost movement at age 16, and is the first woman to receive the implant. Sharing the moment on X (formerly Twitter), Crews posted: 'I tried writing my name for the first time in 20 years. I'm working on it. Lol #Neuralink.' In shaky writing on her laptop screen is the word 'Audrey'. READ MORE ON NEURALINK Musk, co-founder of Neuralink, replied to the post, saying: "She is controlling her computer just by thinking. Most people don't realise it is possible."

Neanderthals likely ate fermented meat with side of maggots
Scientists long thought that Neanderthals were avid meat eaters. Based on chemical analysis of Neanderthal remains, it seemed like they had been feasting on as much meat as apex predators such as lions and hyenas. But as a group, hominins - that's Neanderthals, our species and other extinct close relatives - aren't specialised flesh eaters. Rather, they are more omnivorous, eating plenty of plant foods, too. It is possible for humans to subsist on a very carnivorous diet. In fact, many traditional northern hunter-gatherers such as the Inuit subsisted mostly on animal foods. But hominins simply cannot tolerate consuming the high levels of protein that large predators can. If humans eat as much protein as hypercarnivores do over long periods without consuming enough other nutrients, it can lead to protein poisoning - a debilitating, even lethal condition historically known as "rabbit starvation". So, what could explain the chemical signatures found in Neanderthal bones that seem to suggest they were healthily eating tons of meat? I am an anthropologist who uses elements such as nitrogen to study the diets of our very ancient ancestors. New research suggests a secret ingredient in the Neanderthal diet that might explain what was going on - maggots. Isotope ratios reveal what an animal ate The ratios of various elements in the bones of animals can provide insights into what they ate while alive. Isotopes are alternate forms of the same element that have slightly different masses. Nitrogen has two stable isotopes: nitrogen-14, the more abundant form, and nitrogen-15, the heavier, less common form. Scientists denote the ratio of nitrogen-15 to nitrogen-14 as δ¹⁵N and measure it in a unit called permil. As you go higher up the food chain, organisms have relatively more of the isotope nitrogen-15. Grass, for example, has a very low δ¹⁵N value. A herbivore accumulates the nitrogen-15 that it consumes eating grass, so its own body has a slightly higher δ¹⁵N value. Meat-eating animals have the highest nitrogen ratio in a food web; the nitrogen-15 from their prey concentrates in their bodies. By analysing stable nitrogen isotope ratios, we can reconstruct the diets of Neanderthals and early Homo sapiens during the late Pleistocene, which ran from 11,700 to 129,000 years ago. Fossils from various sites tell the same story - these hominins have high δ¹⁵N values. High δ¹⁵N values would typically place them at the top of the food web, together with hypercarnivores such as cave lions and hyenas, whose diet is more than 70% meat. But maybe something else about their diet was inflating Neanderthals' δ¹⁵N values. Uncovering the Neanderthal menu It is suspected that maggots could have been a different potential source of enriched nitrogen-15 in the Neanderthal diet. Maggots, which are fly larvae, can be a fat-rich source of food. They are unavoidable after you kill another animal, easily collectible in large numbers and nutritionally beneficial. To investigate this possibility, a dataset that was originally created for a very different purpose was used: a forensic anthropology project focused on how nitrogen might help estimate time since death. I had originally collected modern muscle tissue samples and associated maggots at the Forensic Anthropology Center at University of Tennessee, Knoxville, to understand how nitrogen values change during decomposition after death. While the data can assist modern forensic death investigations, in our current study we repurposed it to test a very different hypothesis. We found that stable nitrogen isotope values increase modestly as muscle tissue decomposes, ranging from -0.6 permil to 7.7 permil. This increase is more dramatic in maggots feeding on decomposing tissue: from 5.4 permil to 43.2 permil. To put the maggot values in perspective, scientists estimate δ¹⁵N values for Pleistocene herbivores to range between 0.9 permil to 11.2 permil. Maggots are measuring up to almost four times higher. Our research suggests that the high δ¹⁵N values observed in Late Pleistocene hominins may be inflated by year-round consumption of ¹⁵N-enriched maggots found in dried, frozen or cached animal foods. Cultural practices shape diet In 2017, my collaborator John Speth proposed that the high δ¹⁵N values in Neanderthals were due to the consumption of putrid or rotting meat, based on historical and cultural evidence of diets in northern Arctic foragers. Traditionally, Indigenous peoples almost universally viewed thoroughly putrefied, maggot-infested animal foods as highly desirable fare, not starvation rations. In fact, many such peoples routinely and often intentionally allowed animal foods to decompose to the point where they were crawling with maggots, in some cases even beginning to liquefy. This rotting food would inevitably emit a stench so overpowering that early European explorers, fur trappers and missionaries were sickened by it. Yet Indigenous peoples viewed such foods as good to eat, even a delicacy. When asked how they could tolerate the nauseating stench, they simply responded, "We don't eat the smell." Neanderthals' cultural practices, similar to those of Indigenous peoples, might be the answer to the mystery of their high δ¹⁵N values. Ancient hominins were butchering, storing, preserving, cooking and cultivating a variety of items. All these practices enriched their paleo menu with foods in forms that nonhominin carnivores do not consume. Research shows that δ¹⁵N values are higher for cooked foods, putrid muscle tissue from terrestrial and aquatic species, and, with our study, for fly larvae feeding on decaying tissue. The high δ¹⁵N values of maggots associated with putrid animal foods help explain how Neanderthals could have included plenty of other nutritious foods beyond only meat while still registering δ¹⁵N values we're used to seeing in hypercarnivores. We suspect the high δ¹⁵N values seen in Neanderthals reflect routine consumption of fatty animal tissues and fermented stomach contents, much of it in a semi-putrid or putrid state, together with the inevitable bonus of both living and dead ¹⁵N-enriched maggots. What still isn't known Fly larvae are a fat-rich, nutrient-dense, ubiquitous and easily procured insect resource, and both Neanderthals and early Homo sapiens, much like recent foragers, would have benefited from taking full advantage of them. But we cannot say that maggots alone explain why Neanderthals have such high δ¹⁵N values in their remains. Several questions about this ancient diet remain unanswered. How many maggots would someone need to consume to account for an increase in δ¹⁵N values above the expected values due to meat eating alone? How do the nutritional benefits of consuming maggots change the longer a food item is stored? More experimental studies on changes in δ¹⁵N values of foods processed, stored and cooked following Indigenous traditional practices can help us better understand the dietary practices of our ancient relatives.
