According to Professor Katerina Herberty from the University of Tübingen, “The Middle Pleistocene was crucial for human evolution, marking a period when complex behaviors emerged.”

“This era also showcases the earliest reliable evidence of the targeted use of plants for technological purposes.”

The 430,000-year-old wooden tools discovered at the Marathusa 1 site, led by Professor Harbati and his team, consist of worked alder trunks and small willow/poplar artifacts.

The primary tool is made from alder wood (Alnus sp.) and features engraving marks along with associated stop and chop marks, indicating intentional shaping.

This approximately 81 cm long artifact displays signs of usage consistent with a multifunctional rod likely employed for paleolakeshore excavation.

The second tool, a small piece of willow/poplar (Salix sp./Populus sp.), measures 5.7 cm and exhibits signs of rounding.

This object shows two signs of potential processing, suggesting that growth rings have been removed from one end.

Researchers hypothesize that this small wooden tool’s function remains uncertain but may have been utilized for modifying stone tools.

Alongside these wooden tools, scientists uncovered butchered remains of an elephant with straight tusks (Paleoloxodon Antique), as well as stone artifacts and processed bones.

Dr. Annemieke Milks, a researcher at the University of Reading, states, “Unlike stone artifacts, wooden objects need special conditions to survive over long durations.”

“We meticulously examined all tree remains, analyzing the surfaces under a microscope.”

“Our findings revealed clear evidence of cutting and carving on these two objects, strongly indicating that early humans intentionally shaped them.”

Additionally, researchers found a large fragment of an alder trunk exhibiting deep carved stripes, interpreted as fossilized claw marks from a large carnivore. This suggests potential competition between early humans and carnivores at this site.

Evidence of cuts and damage on the elephant remains indicate that early hominins had access to the carcass, while gnawing marks reveal subsequent carnivorous activity.

Dr. Milks added, “Previous discoveries of ancient wooden tools have occurred in countries such as Britain, Zambia, Germany, and China, comprising weapons, digging sticks, and tool handles.” However, she noted that these finds date newer than the Marathusa 1 artifacts.

“The only evidence of ancient wood used by humans, dating to around 476,000 years ago, comes from the Kalambo Falls site in Zambia, where the wood served as structural material rather than tools.”

“We have now identified the oldest known wooden tools and the first of their kind from southeastern Europe,” emphasized Professor Herberty.

“This discovery highlights the exceptional conservation conditions at the Marathusa 1 site.”

“The concurrent evidence of human activity and large carnivores in the vicinity of the butchered elephant indicates a competitive dynamic between them.”

Details of these findings are published in Proceedings of the National Academy of Sciences.

Historic Discovery: Oldest Supernova in History Illuminates Earliest Star

James Webb Space Telescope image of SN Eos supernova

Astronomers have identified a colossal star’s explosion shortly after the universe emerged from the Cosmic Dark Ages, offering insights into the birth and demise of the first stars.

When a star exhausts its fuel, it explodes in a spectacular event known as a supernova. While nearby supernovae are exceedingly bright, the light from ancient explosions takes billions of years to reach Earth, fading into invisibility by the time it arrives.

This is why astronomers typically detect distant supernovae only during exceptional circumstances, such as Type Ic supernovae, which are the remnants of stars stripped of their outer gas and producing intense gamma-ray bursts. However, the more common Type II supernova, the predominant explosion observed in our galaxy, occurs when a massive star depletes its fuel but remains too faint for casual observation.

Notably, David Coulter, a professor at Johns Hopkins University in Baltimore, Maryland, and his team utilized the James Webb Space Telescope to discover a Type II supernova named SN Eos, dating back to when the universe was only 1 billion years old.

Fortunately, the supernova’s explosion took place behind a vast galaxy cluster, whose potent gravity amplified the light, rendering SN Eos dozens of times brighter than it would typically appear, facilitating detailed studies.


Researchers meticulously analyzed the light spectrum from SN Eos, confirming it as the oldest supernova detected via spectroscopy. Their findings denote it as a Type II supernova, attesting to its origins from a massive star.

Additionally, evidence suggests that the progenitor star contained remarkably low quantities of elements beyond hydrogen and helium—less than 10% of the elemental abundance present in the Sun. This aligns with theories about the early universe, where multiple stellar generations hadn’t existed long enough to create heavier elements.

“This allows us to quickly identify the type of stellar population in that region. [This star] exploded,” stated Or Graul from the University of Portsmouth, UK. “Massive stars tend to explode shortly after their formation. In cosmological terms, a million years is a brief interval, making them indicators of ongoing star formation within their respective galaxies.”

Light from such vast distances is typically emitted by small galaxies, allowing astronomers to infer the average characteristics of the stars within these galaxies. However, studying individual stars at these distances tends to be unfeasible. As noted by Matt Nicholl of Queen’s University, Belfast, UK, “This discovery provides us with exquisite data on an individual star. [Distance] has kept us from observing an isolated supernova here, but the data confirms this star’s uniqueness compared to others in the local universe.”

This observation occurred just a few hundred million years following the Era of Reionization, a pivotal period in the universe’s history. During this time, light from the inaugural stars began ionizing neutral hydrogen gas, transitioning it into translucent ionized hydrogen. This relates to SN Eos, as it serves as a supernova from a time we would expect to see.

“This discovery closely coincides with the reionization era when the universe emerged from darkness, permitting photons to travel freely once more and allowing us to observe,” said Graul.

Paleontologists Uncover Earliest Evidence of Ancient Honey Bees Nesting in Vertebrate Fossil

Bees exhibit an extraordinary range of species and behavior, from solitary types that nest in burrows to social variants that construct intricate nests. This nesting diversity is partially captured in the fossil record, with trace fossils dating from the Cretaceous to the Holocene. In a recent study, Field Museum paleontologist Lázaro Vignola López and his colleagues unveil novel nesting behaviors based on trace fossils unearthed from Late Quaternary cave deposits on the Caribbean island of Hispaniola. Osnidam Almontei was discovered within the cavity of a vertebrate corpse.

“The initial descent into the cave isn’t very deep. You secure a rope to the side and rappel down,” Dr. Vignola López explained.

“Entering at night, you can spot the eyes of tarantulas residing there. As you navigate through the 10-meter-long underground tunnel, fossils start to emerge.”

Fossil layers were separated by carbonate deposits formed during rainy periods in antiquity.

Although rodents made up most of the fossils, remains of sloths, birds, and reptiles—over 50 species in total—were also found. Together, these fossils narrate a compelling story.

“We hypothesize this cave served as a home for owls over generations, potentially for hundreds or even thousands of years,” Dr. Vignola López remarked.

“The owl would venture out to hunt and return to the cave to regurgitate pellets.”

“We’ve collected fossils of the prey the owl consumed, its own remains, and even bones of turtles and crocodiles that may have inadvertently fallen into the cave.”

Dr. Vignola López and his colleagues observed that the sediments in empty tooth sockets of mammalian jaws didn’t accumulate randomly.

“The surface was notably smooth and slightly concave, which is unusual for sediment burial. I noticed this pattern across multiple specimens and thought to myself, ‘There’s something peculiar here.’ It reminded me of a hornet’s nest,” he noted.

Many well-known nests constructed by bees and wasps belong to social species that coexist in large colonies, raising their young together—like the bees in honeycombs or paper wasp nests.

“However, the majority of bee species are solitary. They deposit eggs in small cavities and leave pollen for their larvae’s nourishment,” Dr. Vignola López continued.

“Some bee species create nests in tree hollows, in the ground, or utilize vacant spaces. Certain species in Europe and Africa even nest within discarded snail shells.”

To investigate the possible insect nests within the cave fossils, the researchers conducted CT scans and X-rays of the bones, capturing 3D images of the compacted soil in the tooth sockets without damaging the fossils.

The shape and composition of the deposits bore similarities to mud nests created by some contemporary bee species. Some of these nests contained ancient pollen grains that mother bees had sealed for their larvae.

The researchers propose that bees combined saliva and soil to construct small nests for their eggs, smaller than the eraser on a pencil.

Nesting within larger animal bones provided protection for bee eggs from potential predators such as wasps.

While the bees themselves were not preserved, the unique characteristics of the nests allowed for a taxonomic classification.

They named the nests Osnidam Almontei, in honor of the scientist Juan Almonte Milan, who first discovered this cave.

“Since no bee remains were found, they may have belonged to a currently existing species. Our knowledge on the ecology of various bee species in these islands is limited,” Dr. Vignola López stated.

Scientists speculate that this behavior arises from a combination of factors. With little soil covering the limestone terrain in this region, bees may have opted for caves as their nesting sites, rather than digging into the ground like many other species.

Additionally, this cave had been home to generations of owls, with numerous owl pellets accumulating over the years, providing the bees with ample use of the bones the owls left behind.

“This finding illustrates the peculiarities of bees. They can be surprising, and it emphasizes the importance of meticulous examination when studying fossils,” Dr. Vignola López remarked.

Archaeologists Uncover Earliest Evidence of Fire Creation

Archaeologists have discovered a heated deposit that is 400,000 years old, along with a fire-cracked flint hatchet in Burnham, Suffolk, England, as well as two pieces of pyrite—a mineral historically used to create sparks from flint. This finding suggests that humans were capable of making fire approximately 350,000 years earlier than previously thought.

The ability to start and control fire represents a significant milestone in human evolution. Fire provided essential warmth, protection from predators, and enabled cooking, thereby broadening the range of edible foods.

Evidence of fire in areas occupied by humans dates back over a million years.

Nonetheless, pinpointing when humans first learned to ignite fire remains challenging.

Fire likely began with early humans taking advantage of natural wildfires before they developed the skill to deliberately start their own fires.

Previously, indications of early fire use were found at Neanderthal locations in France dating back 50,000 years, where hand axes possibly used for striking pyrite to create sparks were discovered.

Recent findings by Professor Nick Ashton of the British Museum and the Institute of Archaeology at University College London, along with his team, indicate that fire-making might have been practiced at the Burnham site as far back as 400,000 years ago.

Archaeologists uncovered heated deposits in the ancient soil, along with a flint hatchet damaged by fire.

These indicators suggest that fires were maintained purposefully within human habitats, marking the third piece of evidence that fire-starting was intentional.

Two pyrite fragments were found at the site. Due to the mineral’s rarity in the area, researchers hypothesize that the pyrite may have been deliberately transported to the site for fire-starting purposes.

Together, these discoveries illustrate the sophisticated behaviors of early humans at the Burnham location.

For instance, these hominins may have comprehended the ignition properties of pyrite and incorporated it into their fire-starting techniques.

Mastering this skill would have offered numerous benefits, including cooking abilities and advancements in technology, such as the creation of adhesives for tools, potentially influencing significant developments in human behavior.

Professor Chris Stringer, a paleoanthropologist at the Natural History Museum in London, commented: “Based on the morphology of contemporary fossils from Swanscombe, Kent, and Atapuerca in Spain, we believe the individuals who ignited the Burnham fire 400,000 years ago were early Neanderthals, and early Neanderthal DNA has been preserved.”

“This represents the most astounding discovery of my career, and I take great pride in the collaborative effort that led to this groundbreaking conclusion,” said Professor Ashton.

“It’s astonishing that some of the oldest Neanderthal groups understood the characteristics of flint, pyrite, and tinder at such an early time.”

“The implications of this finding are immense,” stated Dr. Rob Davies, project curator at the British Museum.

“The capability to create and manage fire was one of the most crucial turning points in human history, offering practical and social advantages that significantly shaped human evolution.”

“This remarkable discovery shifts this pivotal moment back to about 350,000 years ago.”

The study detailing these findings is published in this paper in today’s edition of Nature.

Earliest RNA Sample Discovered from a Woolly Mammoth

The skin and muscles of Yuka’s left front leg are remarkably intact.

love darren

The oldest known RNA has been obtained from a woolly mammoth preserved in Siberian permafrost for close to 40,000 years.

This specimen, named Yuka and found in 2010, is regarded as the best-preserved woolly mammoth (Mammuthus primigenius) identified to date. Initially believed to be a young female that perished between the ages of 6 and 8—likely due to an attack by a cave lion.

Researchers have successfully extracted DNA from various woolly mammoths, including some over a million years old. Advances in genome reconstruction have sparked hopes of potentially reviving this species through genetic engineering.

DNA carries the genetic blueprint for protein production in animals. When a specific gene is activated, the code is transcribed into another molecule known as RNA, which is far less stable than DNA and typically breaks down within hours after death.

The oldest RNA previously retrieved was from a wolf preserved in Siberian permafrost over 14,000 years ago. Recently, love darren from Stockholm University has extracted nearly three times the RNA amount from Yuka’s leg than had been recorded before.

The research team employed techniques similar to those used to extract RNA from contemporary samples, fine-tuning them to target smaller and older molecules.

“Yuka is exceptionally well preserved,” remarks Darren. “The specimen likely experienced deep freezing and prolonged burial in permafrost, evidenced by the preservation of both muscle tissue and wool-like fur. This significantly boosts the chance of RNA preservation.”

However, Yuka’s temporary thawing during transport from northeastern Siberia to Yakutsk posed a challenge. “We assumed that any truly ancient RNA still present in the sample would have degraded into smaller fragments,” says Darren.

The team exercised extreme caution to prevent sample deterioration and avoid contamination. “We utilized liquid nitrogen for grinding, along with sterile materials, filtered air, protective clothing, and controlled lab conditions to eliminate modern contamination in sequencing data,” he explains.

RNA sequencing reveals which genes were active at the time of the animal’s death. In the RNA extracted from Yuka’s muscle and skin, the researchers identified signs of gene activity associated with muscle metabolism and cellular stress, aligning with the hypothesis of Yuka’s death resulting from a cave lion’s attack.

A surprising finding was that a combination of DNA and RNA analysis led the research team to conclude that Yuka was actually male. “I’ve anticipated something like this for a long time,” shares Darren. “Even though Yuka is remarkably preserved for being 40,000 years old, it’s not entirely intact, making it difficult to determine an organism’s morphological sex.”

Researchers also probed for RNA viruses such as influenza and coronaviruses but found no significant results. “Yet I believe we will see future studies on Ice Age RNA viruses,” Darren mentions. “For instance, we possess some Pleistocene bird carcasses that would be intriguing to investigate concerning avian influenza.”

Darren, a scientific advisor to Colossal Biosciences, the company claiming to have revived the dire wolf earlier this year, stated that the RNA sequences retrieved in this study do not directly contribute to the revival of the mammoth. However, the study may offer valuable insights into genes responsible for certain traits. “In the future, mammoth RNA profiles might uncover how specific traits, such as wool, were genetically regulated in these animals.”

Merlin Crossley, a researcher at the University of New South Wales in Sydney, noted that while acquiring such ancient RNA is an impressive feat, it doesn’t reveal much about mammoth ecology. “It’s akin to maneuvering a light airplane under the Sydney Harbor Bridge,” he explained. “It’s a remarkable technical accomplishment, but we gain little insight from it.”

Crossley believes that while older RNA samples may be unearthed in the future, the limits of RNA’s longevity are close at hand. Given the rarity of specimens like Yuka’s, he concludes that it’s unlikely that additional mammoths will yield significant information.

Ancient Silver Goblet Features the Earliest Depiction of the Universe’s Creation

“Ain Samiya’s Silver Goblet”

Israel Museum, Jerusalem/Ardon Bar Hama

A silver chalice dating back 4,300 years, found in Palestine’s West Bank, displays a depiction of the universe’s formation from primordial chaos, marking it as the oldest recorded visual interpretation of a creation myth.

“It’s a one-of-a-kind design,” says Eberhard Sanger from the Lewisian Research Foundation in Switzerland. “It conveys a complex narrative using a minimal number of lines.”

Measuring about 8 cm in height, the “Ain Samiya” goblet was uncovered 55 years ago in an ancient tomb located a few miles northeast of Ramallah, on the western edge of the Fertile Crescent, an area where early civilizations thrived.

The goblet features two distinctive scenes. The first shows a large serpent confronting a chimera with a human upper body and animal legs, positioned on a small flower-like circle. The second scene depicts a smiling serpent lying on the ground beneath a much larger flower-like circle, supported by two humanoid figures—of which only one is currently visible due to the goblet’s damage.

Archaeologists of the 1970s proposed that these scenes could represent Enuma Elish, the Babylonian creation myth in which the primordial entity Tiamat is overcome by the god Marduk, resulting in Tiamat’s body transforming into heaven and earth. However, Zanger notes that this interpretation has its shortcomings; notably, there are no battle representations on the goblet, and it is approximately 1,000 years older than Enuma Elish itself.

<section></section>
<span class="js-content-prompt-opportunity"/>
<p>This has led other scholars to suggest alternative meanings. For instance, they propose that the goblet might represent the cyclical rebirth of a year and the passing of another.</p>
<p>Nonetheless, Zanger and his associates, including independent researcher <a href="https://utoronto.academia.edu/DanielSarlo">Daniel Sarlo</a> from Toronto, and <a href="https://fabiennehaasdantes.academia.edu/">Fabienne Haas Dantes</a> from the University of Zurich, argue that the original interpretation remains the most accurate. They contend that the scenes depict the creation of the universe, drawing from ancient creation stories that predate even <em>Enuma Elish</em>.</p>

<p>Zanger's research team views the first scene as ambiguous. The chimera signifies a weaker god combined with an animal. The small flower-like circles beneath its legs symbolize the powerless sun. A colossal serpent dominates this chaos. In contrast, the second scene reveals that order has emerged from chaos, with gods distinguished from animals, transforming into potent humanoid figures. They raise the powerful sun atop a "vessel of heaven," indicating the separation of heaven from earth, while the chaotic serpent lies defeated beneath the sun.</p>
<p>Zanger also mentions that cuneiform texts from another area of the Fertile Crescent, dating similarly to the goblet, discuss how deities divided heaven and earth. This indicates that by the time of the goblet's creation, the locals had already contemplated the theme of world creation. "The remarkable aspect of this artifact is that it allows us to glimpse their conception of this narrative," he states.</p>
<p><a href="https://independent.academia.edu/JLisman">Jan Lisman</a>, an independent researcher from the Netherlands, remains skeptical of this interpretation. "What it depicts is the daily journey of the sun," he argues. "But it certainly does not reflect 'origin' or 'chaos.'"</p>

<p><a href="https://www.altestestament.unibe.ch/about_us/people/prof_em_dr_schroer_silvia/index_eng.html">Sylvia Schroer</a>, a professor at the University of Bern, Switzerland, shows some willingness to entertain the notion that the goblet signifies world creation. However, she believes a different aspect of the new analysis is problematic.</p>

<p>According to Zanger, some images on the Ain Samiyah goblet, notably the giant snake, resonate with ancient cosmological tales from the Fertile Crescent and adjacent areas. They posit that this implies a profound connection among various creation myths which may trace back to a singular, more ancient narrative. Illustrating this, they cite a celestial vessel resembling that in the goblet, which is carved on a pillar at Göbekli Tepe in modern-day Turkey, a location dating back 11,500 years—7,000 years prior to the goblet's creation. "This is astonishing," Zanger remarks.</p>
<p>Nonetheless, Schroer argues that it might be too speculative to assert that all creation narratives in the region are tightly intertwined. "Even with similarities, it doesn't necessitate clear influence," she maintains.</p>

99-Million-Year-Old Amber Contains the Earliest Mosquito Larvae

This newly discovered fossil, preserved in amber from Myanmar’s Kachin region, marks the first instance of a mosquito larva found in amber and represents the earliest immature mosquito of the Mesozoic era, designated as a new genus and species: Cletosabetes primaevus. This discovery strongly suggests that the mosquito family Culicidae has its origins in the Jurassic period and indicates that its larval structure has remained largely unchanged for at least the past 99 million years.

Larva of Cletosabetes primaevus. Image credit: Amaral et al., doi: 10.1016/j.gr.2025.09.011.

Mosquitoes comprise a vast group of insects, with over 3,727 known species alive today.

Although small, they are quite noticeable and widely distributed, playing significant roles in ecosystems, human history, and both human and veterinary health.

To date, 31 species of mosquito fossils have been documented. These ancient mosquitoes closely resemble modern species and are classified within the same genus as their modern counterparts.

“The earliest known mosquito fossils are adults, also found in amber dating back about 99 million years,” stated Dr. Andre Amaral from Ludwig-Maximilians-University of Munich and his team.

“Given their morphological distinctions from living species, they are considered part of a separate group, Burmaculicinae, representing an extinct lineage within Culicidae.”

The authors note that Cletosabetes primaevus belongs to the Sabetini group, which includes existing species.

Similar to the larvae of current Sabetini species, this new species’ larvae likely thrived in small water bodies.

“According to currently uncovered fossils, the evolutionary roots of mosquitoes are believed to be in the Jurassic period, roughly 201 to 145 million years ago,” the researchers remarked.

“Molecular phylogeny analyses yield varying conclusions, from the Triassic to Jurassic periods.”

“Our research strongly indicates that mosquitoes had already diversified during the Jurassic period, with their larval structure remarkably consistent for nearly 100 million years.”

“This finding challenges previous notions regarding the early evolution of this insect group and offers fresh insights into its evolutionary ecology.”

A segment of amber containing Cletosabetes primaevus larvae was sourced from the Kachin Amber Mine in Myanmar’s Hukaung Valley.

This amber dates back to the Late Cretaceous, about 98.79 million years ago.

“This fossil stands out as the larva closely resembles modern species. Unlike other mosquito fossils from this period, it displays distinct morphological features no longer found in today’s species,” Dr. Amaral explained.

A paper detailing Cletosabetes primaevus was published in this month’s edition of Gondwana Research.

The Earliest Known Dome-Headed Dinosaurs of Mongolia

Artistic representation of the pachycephalosaur Zavacephale rinpoche

Masaya Hattori

A dinosaur with a dome-shaped head, discovered in Mongolia, boasted a mouth full of formidable teeth and an unusually large eye socket on its skull.

The newly identified species, named Zavacephale rinpoche, roamed the Earth during the early Cretaceous period about 108 million years ago. It belongs to a group known as the Pachycephalosaurs. These dinosaurs were characterized by their dome-like skulls, which may have served defensive purposes or been used for social and mating displays.

Paleontologists exploring the Gobi Desert of Mongolia report having uncovered a fossilized skull protruding from the rocks, likening it to a “cabochon gem.” Lindsey Zanno from the North Carolina Museum of Natural Sciences stated, “This is how we came up with the species name Rinpoche, which translates to ‘precious things’ in Tibetan.”

Z. rinpoche represents the most complete specimen of its kind discovered to date, being about 15 million years younger than other known Pachycephalosaur species. It includes nearly the entire skull and limb bones, significant portions of the vertebrae, and pelvic bones. Additionally, the team was able to recover hand bones and gastroliths, which were likely used to grind food.

The dome of the fossil shows distinct dimples, possibly indicating other unidentified features of the head.

“The skull of Pachycephalosaurs is quite striking,” says Zanno. “They not only feature domes, but also bone spikes and nodes surrounding their skulls for aesthetic purposes. These embellishments served as sort of decorative accessories for the dome.”

To ascertain the age at which the dinosaur perished, researchers examined thin slices of the bones from its lower limbs. They classified it as a “teenager,” measuring approximately one meter in length and weighing just under six kilograms. It remains uncertain how large it might have become as an adult, though other members of its group reached lengths exceeding four meters and weights around 400 kilograms.

“The preserved tissues show two growth rings, suggesting that it was actively growing at the time of its death,” noted Zanno. “The spinal bones exhibit no signs of wear, indicating room for further growth.”

CT scans of the skull dome revealed it was fully developed, emphasizing its significance at a younger age.

The Earliest Human Mummies: A 14,000-Year-Old Smoking Process

SEI 265721258

Carefully preserved through smoking practices up to 14,000 years ago, a human body has been found at archaeological sites in Southeast Asia, making it the world’s oldest known mummy.

This custom continues today among the Dani people in West Papua, Indonesia, who mummify their deceased relatives by exposing them to smoke and treat them with care and respect as part of the household. Many of these mummies are found in a tightly bound squatting position.

Similar “highly flexed” ancient remains have also been discovered in Australia, China, the Philippines, Laos, Thailand, Malaysia, South Korea, and Japan.

Hsiao-Chun Hung from the Australian National University in Canberra noted the striking similarities between burial remains excavated in relation to Dani traditions while working on ancient skeletons in Vietnam in 2017.

Hung and her team analyzed the burial practices of 54 hunter-gatherers from 11 archaeological sites across Southeast Asia dated between 12,000 and 4,000 years ago to uncover evidence of smoking. Most sites were based in northern Vietnam and southern China.

Numerous remains displayed clear signs of partial burning, though not enough to indicate cremation. The researchers utilized two analytical methods, X-ray diffraction and infrared spectroscopy, on several bone samples to assess thermal exposure.

Over 90% of the 69 skeletal samples displayed indications of heat exposure. The findings suggest that while human remains were not subjected to extreme temperatures, they likely endured lower temperatures, potentially from smoking for extended periods.

The oldest mummy examined by a Vietnamese team from Hang Cho dates back over 11,000 years. However, a tightly bound skeleton from another site, Hang Mooy, indicates practices recorded over 14,000 years ago. “We didn’t need X-rays or infrared to analyze this one because it’s evidently partially burned and visible to the naked eye,” explains Hung.

Previously, the oldest known mummy was believed to come from northern Chile, approximately 7,000 years ago, and ancient Egypt around 4,500 years ago.

Hung suggests that the evidence indicates this burial tradition likely spread across southern China and Southeast Asia at least 14,000 years ago, as agricultural societies became prevalent in the region around 4,000 to 3,500 years ago. The constricting bindings of mummified bodies may have facilitated their transport, she notes.

Ethnographic studies indicate that these traditions persisted in southern Australia until the late 19th and early 20th centuries, according to Hung. “Additionally, our literature review in the New Guinea highlands reveals that these practices continue among some communities today.”

“Our results signify a unique blend of techniques, traditions, culture, and a profound connection to ancestry that spans an extraordinary timeframe, covering vast regions from the Paleolithic era to the present,” she states.

Vito Hernandez from Flinders University in Adelaide suggests that this study challenges long-standing beliefs that such practices were exclusive to arid regions like Chile’s Atacama and Egypt’s Nile Valley. “It highlights the role of tropical environments in nurturing distinct mortuary traditions among early modern humans across the Far East and potentially into the Pacific,” he remarks.

“By extending the timeline of mummification by at least 5,000 years, the Chinchalo culture [of South America] emphasizes Southeast Asia’s role as a center for cultural innovation, demonstrating a deep continuity that connects early Holocene hunter-gatherers with present-day indigenous groups in New Guinea and Australia,” Hernandez adds.

The Galaxy Potentially Discovered by JWST Might Be the Earliest We’ve Ever Observed

SEI 264756217

A potentially newly discovered galaxy from the James Webb Space Telescope

NASA, ESA, CSA, CEERS, G. Gandolfi

Astronomers might have found galaxies that formed very early in the universe, approximately 200 million years apart from their closest counterparts, but they caution that alternative explanations could exist.

Giovanni Gandolfi from the University of Padua, along with his team, examined data from the James Webb Space Telescope (JWST) in search of distant cosmic formations from the universe’s 13.8 billion-year timeline.

The greater the distance of a galaxy from Earth, the longer it takes for its light to reach us, and it will be redshifted due to the universe’s expansion.

Until now, the earliest confirmed galaxy identified by JWST, named Mom-Z14, has a redshift of 14.4, indicating that it has been moving toward us since the universe was just 280 million years old. Gandolfi and his colleagues, however, have reported finding 32 intriguing objects with redshifts, placing them at a time when the universe was merely 90 million years old. They have named this discovery Capotauro after the Italian mountains.

“Capotauro could represent the most distant galaxy we’ve encountered,” states Gandolfi.

The team derived their conclusion from observing minor fluctuations in a deep JWST survey of the sky that resemble a distant galaxy. By utilizing various filters on the telescope, they were able to determine the redshift of the light emitted by the galaxy, arriving at a count of 32.

If validated, this object might represent a very young galaxy in formation, or potentially a primitive black hole enveloped by a dense atmosphere.

Nonetheless, this presumed galaxy appears uncommonly bright, akin to those observed in later redshift instances like Mom-Z14, suggesting it has a mass approximating a billion times that of the Sun.

For a galaxy to reach such mass, its efficiency in converting gas into stars must be near 100%, according to Nicha Reese Chawarit from the National Institute of Astronomy in Thailand, indicating that the stars cannot explode. Modelling, however, suggests that achieving 10-20% or even lower is plausible. “I believe there’s something amiss,” she remarks.

If this is not a galaxy, Gandolfi and his team propose that the object could alternatively be a brown dwarf (a star that didn’t ignite). These alternative theories are also compelling, Gandolfi notes, particularly if it is a cold brown dwarf or distant planet, possibly 6000 light years away and at room temperature.

“It could represent one of the first substellar objects ever formed in our galaxy,” adds Gandolfi.

To confirm this, the team requires additional observing time on the JWST to precisely analyze the light from the object. Leethochawalit supports the notion that it may not be a galaxy but also states that such follow-up research could still be worthwhile.

“If it turns out to be a galaxy with a redshift of 32, then a lot of our previous assumptions might be entirely wrong,” she states.

The Earliest High-Speed Radio Burst Illuminates Early Star Formation

A magnetar, a type of neutron star, can be the source of fast radio bursts

Science Photo Library/Alamy

A peculiar burst of light from the early universe aids astronomers in mapping elusive gases found between galaxies, much like flashlights in dark spaces.

The Fast Radio Burst (FRB) is an extremely brief yet potent burst of radio frequency emissions that has puzzled astronomers since its discovery in 2007. Currently, we know of only a few thousand instances in the universe, leaving much still to be understood about them, especially as most originate from galaxies neighboring the Milky Way.

Now, Manisha Kaleb from the University of Sydney, Australia, along with her research team, has identified a remarkably distant FRB, tracing back to a galaxy that existed merely 3 billion years post-Big Bang.

Kaleb and her collaborators first detected a burst designated 20240304B using the South African Meerkat Radio Telescope in March 2024, corroborating their findings with observations from the James Webb Space Telescope. They determined that the burst originated from a small, faint galaxy that appeared relatively youthful, characterized by rapid star formation.

“This discovery is extraordinarily distant,” stated Jason Hessel from the University of Amsterdam, Netherlands. The FRB 20240304B is from an epoch in the universe’s timeline known as the ‘midday’ of the universe, a period when the rate of new star formation peaks. This hints that during the galaxy’s formative years, this FRB—and possibly others—may have stemmed from a young star that underwent a supernova and collapsed into a magnetar, according to Hessel.

A key reason astronomers focus on FRBs lies in their ability to shine a light on ionized gases and lost electrons from radiation emitted by stars, which constitute most of the universe’s matter. Understanding its distribution is crucial for unraveling how larger structures—such as stars and galaxies—form. However, like the FRB, this gas remains largely invisible unless illuminated by a light source.

“This luminous flash reveals all the ionized material between us and the origin of the flash, allowing us to map both the gas and the magnetic fields amidst the stars and galaxies,” Hessel added.

The discovery of FRB 20240304B implies that the universe’s first stars were actively ionizing their surroundings, which can help establish a timeline of when these stars first ignited, according to Anastasia Fialkov from Cambridge University. The insights gleaned will only enhance with the detection of even more distant FRBs.

Arizona’s Unique Bone Bed Uncovers North America’s Earliest Known Pterosaurs

Paleontologists have uncovered the fossilized jawbone of a newly identified pterosaur species, along with a multitude of fossils, including one of the world’s oldest turtles, in a secluded bone bed located within Petrified Forest National Park in Arizona, USA.

The newly discovered pterosaur species, Eotephradactylus chintireae, existed in what is now Arizona during the late Triassic period, approximately 209 million years ago.

“The winged reptile was small enough to comfortably perch on a person’s shoulder,” stated Dr. Ben Krigman from the Smithsonian Institution’s National Museum of Natural History.

“One of the most exciting aspects of this discovery was that the teeth remained intact in the bones, making the identification of these animals significantly easier,” added Suzanne McIntier, a volunteer preparer who dedicated 18 years at Fossil Lab at the National Museum of Natural History.

“The teeth-filled jaws provided crucial insights into the lifestyle of the earliest pterosaurs.”

“The worn tips of the teeth suggest a high likelihood that they consumed armored fish and other prey,” she explained.

Eotephradactylus chintireae coexisted with large amphibians, armored crocodile ancestors, frogs, and turtles.

In addition to this flying reptile, paleontologists have found over 1,200 individual fossils, which include bones, teeth, fish scales, and coprolites.

“This collection represents 16 different vertebrate groups that previously inhabited diverse ecosystems,” they noted.

“The braided rivers in this region were teeming with fish, such as freshwater sharks, coelacanths, and ancient amphibians.

The surrounding environment was also home to some of the formidable reptiles that evolved during the early Triassic, including giant alligator-like armored herbivores and predatory creatures.”

The newly identified bone bed is part of the Upper Sinru Formation in Petrified Forest National Park.

“This area of northeastern Arizona was situated in the heart of Pangaea on the supercontinent, positioned just above the equator 209 million years ago,” the researchers added.

“The semi-arid landscape was interspersed with small river channels, which were prone to seasonal flooding. These floods deposited sediment and volcanic ash into the channels.”

“One of these floods might have buried creatures that remain in the bone beds. The site is rich in small fossils, making it impossible to excavate all of them in the field.”

The research team believes the new site will help bridge gaps in the fossil record prior to the final extinction event (ETE).

“About 1.5 million years ago, volcanic eruptions linked to the fragmentation of Pangaea drastically altered the world’s climate and led to the extinction of approximately 75% of Earth’s species,” the scientists commented.

“This opened the door for new groups, such as dinosaurs, to emerge and thrive in ecosystems globally.”

“Due to the lack of fossil outcrops from just before the ETE, it is challenging to find direct evidence of this transition on land.”

“This site captures the shift toward a more modern terrestrial vertebrate community, marking the beginning of the flourishing of groups following the Mesozoic era, alongside these older species that survived into the Triassic period.”

“Such fossil beds provide evidence that all these animals coexisted.”

The team’s study was published in Proceedings of the National Academy of Sciences.

Fossils from 73 Million Years Ago Reveal the Earliest Evidence of Bird Nesting in Polar Regions

Polar ecosystems are bolstered and enriched by birds that nest there seasonally, serving as keystone members of these ecosystems. Despite the significant ecological role of polar birds, the origins of high-center nests remain unclear due to limited fossil evidence. A recent study conducted by paleontologists explored an extensive collection of bird fossils from the late Cretaceous Purine Cream Formation in Alaska.

“Birds have existed for 150 million years,” stated Lauren Wilson, a doctoral candidate at Princeton University.

“For a significant portion of that time, they constructed nests in the Arctic.”

In their research, Wilson and colleagues studied the bones and teeth of fossilized birds from the Alaska Prune Creek Formation, dating back 73 million years.

They identified various bird types, including land birds, seagull-like birds, and diving birds that bear similarities to some modern ducks and geese, all of which were nesting in the Arctic while dinosaurs roamed the same territory.

Before this research, the earliest known evidence of breeding birds in the Arctic or Antarctic was approximately 47 million years ago, following the asteroid impact that wiped out 75% of Earth’s species.

“This will extend the timeline by 25-30 million years for records of birds breeding in the polar regions,” remarked Dr. Pat Druckenmiller, director of the University of Alaska Museum.

“The Arctic is recognized as a modern nursery for birds.”

“Finding bird bones from the Cretaceous period is exceptionally rare,” Wilson noted.

“Discovering baby bird bones is almost unheard of, making these fossils particularly significant.”

“We conducted extensive mapping of Alaska for fossil birds—it wasn’t on anyone’s radar,” added Dr. Druckenmiller.

“Now, we are one of the premier locations in the country for bird fossils from the dinosaur age.”

“Given the richness of this information, these small bones and teeth offer exceptional insights into the fauna from that era.”

It remains uncertain whether these newly discovered specimens are the earliest recognized members of Neornithes, a category that encompasses all modern birds.

Some of the newly unearthed bones exhibit skeletal characteristics exclusive to this group. Additionally, like contemporary birds, some did not possess true teeth.

“If they belong to a modern bird lineage, they would represent the oldest fossils ever found,” explained Dr. Druckenmiller.

“Currently, the oldest such fossils are about 69 million years old.”

“However, establishing that requires the discovery of a partial or complete skeleton.”

Survey results I will be featured this week in the journal Science.

Earliest Evidence of Ancient Birds Nesting Beyond the Arctic Circle

Illustration of an ancient bird nesting above the Arctic Circle

Gabriel Ugueto

Recent findings of bone fragments from Alaska indicate that birds have been nesting and breeding in the Arctic for at least 73 million years.

“It’s quite unusual, as raising a newborn in the Arctic is challenging,” explains study author Lauren Wilson from Princeton University.

Currently, around 250 bird species can thrive at the poles. Some migrate great distances to enjoy continuous daylight in summer, while others brave the winter, enduring extreme cold and long periods of darkness. However, knowledge about how these birds first adapted to the highest latitudes remains limited.

Wilson and her team searched for ancient avian traces within the Princreek Formation in northern Alaska, which formed on coastal floodplains about 73 million years ago. At that time, northern Alaska was approximately 1,000-1,600 kilometers closer to the Arctic than it is today.

The researchers retrieved ancient soil samples from several narrow rock layers, encountering temperatures of -30°C (-22°F) in a makeshift tent. “This has definitely been the most demanding fieldwork I’ve undertaken,” Wilson admits.

Back at the lab, they spent hours peering through microscopes at sediments smaller than two millimeters, hunting for tiny fossil bone fragments.

The team uncovered over 50 fossil fragments belonging to ancient birds, primarily from chicks and even embryos. The fossilized bones of these young birds exhibit a sponge-like texture, indicative of rapid bone growth.

Although birds likely began nesting in the Arctic Circle 73 million years ago, these fossils represent the earliest evidence of such behavior, extending the timeline of avian presence back by 30 million years.

However, many fossils are fragmented and do not clarify whether these birds remained year-round or only in the warm summer months.

“The Arctic’s food web, which supports life in extreme cold and darkness, couldn’t exist without the plethora of birds that inhabit high latitudes,” says Steve Brusatte from the University of Edinburgh, who wasn’t involved in the study. “These fossils illustrate that birds have been a vital part of these high-latitude ecosystems for tens of millions of years.”

Wilson’s team identified three major bird groups represented among the fossil fragments: extinct tooth-like birds similar to ducks, extinct tooth-like birds reminiscent of gulls, and various species that may be related to modern birds.

Conversely, the samples did not include bones from older bird groups known as enantiornithines, or “opposite birds.” Gerald Mayle from the Senckenberg Institute in Germany, who also wasn’t part of the study, noted that this finding suggests that more advanced bird ancestors could survive the harsh Arctic conditions due to certain evolutionary advantages that older birds lacked.

The ecosystems that shaped the Princreek Formation existed when non-avian dinosaurs dominated the planet, with evidence that ancient birds coexisted with species like tyrannosaurs and horned ceratopsians in these Arctic environments. Some dinosaurs even nested within the Arctic Circle.

The earliest evidence of transport vehicles is the 22,000-year-old trucks

Illustrations of two types of traboa, or sledge, which may be used by ancient people in North America

Gabriel Uguet

Drugmarks and human footprints, composed up to 22,000 years ago, have been found at several sites in White Sands National Park in New Mexico. These are thought to have been made by people pulling long pieces of wood stacked with goods, and are the earliest evidence of such activities.

This type of primitive vehicle is known as the trabore. “It’s basically a wheelless wheel.” Matthew Bennett He is a member of a team studying track at Bournemouth University in the UK.

They were widely used all over the world, but this is the oldest evidence of their use, says Bennett. “Nothing is this old.”

There are many ancient animal footprints in the ancient arid lake of White Sands, but in 2017, human footprints were discovered. In 2019, the team found a long drug mark in connection with human footprints.

“They happen in many different regions, so it was widespread,” Bennett says. “It’s not just an original family using travois.”

Some of the drag marks are made up of a single row. The team believes this was made by a trabore made up of two long wood joined in the form of a triangle. One end of each piece is held in one hand, but there is only a single point of contact on the ground.

The other drag marks consist of two parallel lines. These were probably the result of a trabore where two wood intersected in an x-shape, providing two handles and two ground contact points, which would have been more stable.

Drugmarks often pass through the footsteps of people who are supposed to be pulling a travoy, as expected. In some cases, there are parallel tracks with footprints (often children’s footprints), indicating that others are walking together.

Elsewhere in the world, Trabois was often pulled by dogs and horses, says Bennett, but there is no evidence that white sand people used animals.

Footprint dates, Announced in 2021 challenging the traditional idea that humans did not move to America until the ice sheet began retreating about 15,000 years ago.

“The people in the US debate are very controversial, but we’re pretty confident about the date,” says Bennett. “The traditional story is that the ice sheets have parted ways and they have come, but you can go through before the door closes.” Another recent discovery is that humans have 33,000 years ago. It suggests that they may have reached the Americas.

Bennett says it’s very likely that there are tracks around the world that are not aware of what they are. In fact, he says his team has already discovered similar markings elsewhere in the US.

Vegavis Iaai was an ancient relative of ducks and geese, but it dived for fish like graves and runes

Mark Whitton

The 69 million-year-old skull found in Antarctica is identified as a relative of geese and ducks, making it the oldest known modern bird.

It belongs to the first identified species named 20 years ago Vegavis Iaai, He lived alongside the last dinosaurs in the late Cretaceous period. However, only fragments of the skull had been discovered previously, so scientists were unable to agree on what kind of bird it was, or whether it was a non-vian dinosaur like a bird instead.

The fossil skull was discovered in 2011 on Vega Island off the coast of Antarctic Peninsula. However, it was enveloped in such a fierce rock that the excavator had to scrape away the surrounding stones for hundreds of hours before scanning to reveal details about its interior.

Patrick O'Connor At Ohio University, which worked on the analysis, it says that two almost perfect skull features occur only in modern birds. First, the upper beak is made up of bones, which are primarily called the anterior axis, and the size of the second bone, the maxilla, is significantly reduced, contributing only to a small portion of the bone-palate.

Second, in modern birds, the forebrain is huge compared to the rest of the brain. Like pre-modern birds and dinosaurs of nearby birds Velociraptorthese areas are proportionally much smaller.

meanwhile Vegavis According to O'Connor, it has the ability to clearly mark it as being in the same group of waterfowls as ducks and geese. The bird's beak shape, jaw muscle tissue and hind legs suggest that they were very specialized in diving into the pursuit of fish.

“Perhaps you can easily mistake it for modern graves and runes. This is only related to ducks and each other,” he says.

Jacqueline Nguyen The Australian Museum in Sydney says that this ancient species has been the subject of many debate among bird evolutionary scientists, but new research will help resolve the debate.

“together, [the evidence] It suggests that Vegavis It looks completely different from the duck and geese parents, and this could have been an “evolutionary experiment” in the early history of this group of birds.” says.

Possible Discovery: Stone dating back 12,000 years could be the earliest known wheel-like tool

A pebble with holes excavated from the ruins of Nahal Ein Geb II. Could be an ancient spindle whorl

Laurent Davin

A 12,000-year-old set of perforated pebbles unearthed in northern Israel may be the oldest known hand-spun whorls. This weaving technique may have ultimately helped inspire the invention of the wheel.

The whorl at the bottom of the spindle, which acted as a flywheel, allowed people to efficiently spin natural fibers into yarn and yarn to make clothing and other textiles. Newly discovered stone tools represent early axle-based turning technology, thousands of years before the first carts appeared, researchers say. Talia Yashuv at the Hebrew University of Jerusalem.

“If you look back at the discovery of the first car wheel 6,000 years ago, it didn't just come out of nowhere,” she says. “It's important to look at the functional evolution of how transportation and wheels have evolved.”

Yashuv and her colleagues leoa grossmanAlso at Hebrew University in Jerusalem, researchers studied 113 partially or fully perforated stones at the site of Nahal Ein Geb II, an ancient village just east of the Sea of ​​Galilee. Archaeologists have been discovering these chalky, primarily limestone artifacts since 1972. It was probably made from raw pebbles found along the nearby shore.

The 3D scan revealed that the hole had been drilled part way from both sides using a flint hand drill, but unlike modern drills, it remained in the shape of a narrow, twisted cone, Yashuf said. says. A hole 3 to 4 centimeters in diameter usually passes through the center of gravity of the pebble.


Drilling holes from both sides would have balanced the stone and made it more stable to rotate, Yaszhu said. Some of the partially perforated stones had off-center holes, suggesting they may have been discarded by mistake.

Yashov said the team suspected that the stones, which weigh an average of 9 grams, would be too heavy and “ugly” to be beads, and too light and fragile to be used as fishing weights. Their size, shape, and balance around the hole led researchers to believe that these artifacts were spindle-like whorls.

To test their hypothesis, the researchers created a replica whorl using nearby pebbles and a flint drill. then they asked yonit crystalWhy not try your hand at flax spinning with a traditional craftsman?

“She was really surprised at how well they worked, because they weren't perfectly circular,” Yaszhu says. “But in reality, all you have to do is place the hole in the center of the mass, and it's balanced and works.”

If the stone is indeed a spiral, it could be the oldest known rotating spiral, she says. 1991 study of bone and antler artifacts She found what are likely 20,000-year-old whorls, but added that the researchers who examined them suggested the fragments were probably decorative accents on clothing. Still, people may have been using whorls even earlier, using wood and other biological materials that would have degraded.

The discovery suggests that people were experimenting with spinning techniques thousands of years before they invented potter's wheels and cart wheels about 5,500 years ago, and perhaps the whirlpool helped lead to those inventions. Yaszhu says it's possible.

carol cheval But a professor at the University of the Cote d'Azur in Nice, France, isn't so sure. She explains that the whorl works more like a spinning top than a wheel.

And while the artifact is very likely a whorl, the study lacks microscopic data that would reveal any traces of use, as the threads may have made their mark on the stone over time. , says Cheval.

Trace analysis is “beyond the scope” of the current study, Yashuv said.

Ideally, researchers studying ancient whorls would be skilled at spinning themselves, but the study authors said this was not the case. “It really changes the way you think about archaeological discoveries,” she says.

Earliest Human Occupation of Europe Marked by Discovery of 1.4-Million-Year-Old Stone Tools in Ukraine

Archaeologists have dated ancient stone tools unearthed at the Korolevo site along the Tisza River in western Ukraine to 1.42 million years ago. Therefore, these artifacts are homo erectus — provides the earliest evidence of humans in Europe and supports the hypothesis that the continent was colonized from the east.

“To the east of Europe is the important site of Dmanisi, Georgia, where layers containing human skull remains and stone tools have been reliably dated to approximately 1.85 million to 1.78 million years ago.” said lead author and archaeologist Dr. Roman Garba. Institute of Archeology and Nuclear Physics of the Czech Academy of Sciences, and colleagues.

“The path from Africa to Dmanisi through the Levantine Corridor is consistent with Mode 1 stone artefacts recorded in Jordan's Zarqa Valley, dating back approximately 2.5 million years.”

“The earliest dated evidence of humans in Europe was found at two sites in the southwest: Atapuerca, Spain, the oldest hominin fossils at Sima del Elefante are dated to about 1.2 million years old. and 1.1 million years ago. And in the Valone Cave in southern France, stone artifacts are limited to about 1.2 to 1.1 million years ago.”

“However, the vast spatial and temporal gap separating the Caucasus from southwestern Europe leaves important aspects of the first human dispersal into Europe largely unresolved.”

The Korolebo website is first discovered It was discovered in 1974 by Ukrainian archaeologist Vladislav Gradylin.

It is located near where the Tisza River, a tributary of the Danube, emerges from the eastern Carpathians and spreads southwest across the Pannonian Plain.

“The layers of loess and paleosoil accumulated here are up to 14 meters deep and are known to contain thousands of stone artifacts. Korolevo is an important raw material for their production. ” said co-author Dr. Vitalij Usyk, an archaeologist at the Institute of Archeology of the Czech Academy of Sciences.

“We have identified seven epochs of human occupation in the stratigraphic strata, and at least nine different Paleolithic cultures have been recorded in the region. I lived here until a year ago.”

The stone tools of Korolevo are oldowan stylethe most primitive form of tool making.

“We applied two complementary dating methods to calculate ages from measured concentrations of beryllium-10 and aluminum-26 of cosmic origin,” said lead author, Czech Academy of Sciences Geophysical Research said Dr. John Jansen, a researcher at the institute.

“However, the most accurate age was obtained from our proprietary method based on mathematical modeling known as P-PINI.”

“This study is the first time our new dating approach has been applied to archeology.”

“We expect our new dating approach to have a major impact on archaeology, as it can be applied to highly fragmented deposits – deposits with lots of erosional voids.”

“In archaeology, we almost always find a fragmentary record, whereas the traditional long-distance dating method, magnetostratigraphy, relies on a more continuous record.”

According to the research team, Korolevo is the northernmost known archaeological site. homo erectus.

“The radiometric dating of the first human presence at the Korolevo site not only bridges the large spatial gap between the Dmanisi and Atapuerca sites, but also shows that the first dispersal pulse of humans into Europe came from the east or southeast. This also supports our hypothesis,'' Dr. Garba said.

“Based on climate models and field pollen data, we identified three possible interglacial warm periods during which the first humans most likely followed the Danube migratory corridor to reach Korolevo. .”

New Insights from a 45,000-year-old Bone Hole into the Lives of our Earliest Ancestors

In a cave beneath a medieval German castle, researchers have discovered a bone pit that is said to reveal the secrets of early humans.

The remains, buried in layers of soil in a collapsed cave, contained genetic material from cave bears and hyenas, as well as the bones of 13 early humans who died about 45,000 years ago.

The discovery, described in three papers published Thursday in the journals Nature and Nature Ecology & Evolution, suggests that early humans may have traveled further north earlier than scientists realized. It shows that they went on an adventure, they were able to make spear-shaped tools, and then humans were able to make spear-shaped tools. A means to thrive in temperatures much colder than today’s climate.

These discoveries, perhaps made through the development of new DNA techniques, are reshaping the way scientists understand the time when humans and Neanderthals roamed the European continent.

The discovery could bring scientists closer to understanding why Neanderthals ultimately became extinct and what role humans played in their demise.

John Hawkes, a paleoanthropologist at the University of Wisconsin-Madison who studies ancient human relatives but was not involved in the study, said the study shows that as Neanderthals neared their demise, different human cultures He said this helps solidify the theory that these spots were developing.

“These groups are doing research. They’re going to go to new places. They live there for a while. They have different lifestyles,” he said of early humans. “They feel comfortable moving into areas where Neanderthals were.”

These discoveries were only possible because previous researchers left no stone unturned. Archaeologists in the 1920s and 1930s previously excavated the Ilsenhöhle Cave beneath Ranis Castle in the Thuringia region of Germany. The castle was built over the cave long before any excavations took place.

That’s when scientists were unable to drill into critical layers of the cave, which collapsed after hitting rock more than five feet thick.

In 2016, researchers returned with updated drilling techniques and new forms of analysis. About 24 feet below the surface, they discovered a layer containing leaf tips (like the tip of a spear) and human bone fragments.

The discovery of human bone fragments led researchers to dig deep into material excavated nearly 90 years ago, where they discovered additional skeletal fragments.

Researchers have developed the ability to forecast which organs are most likely to fail earliest

New research suggests that scientists may now be able to predict which organs will fail first, providing an opportunity for doctors to target aging organs earlier, before disease symptoms appear.

A study published in Nature found that one in five healthy adults over the age of 50 have at least one aging organ, increasing their risk of developing disease in that organ over the next 15 years. This discovery provides insight into the aging process of the body.

How does aging occur at different rates in the body?

We all have two ages: the chronological age that increases by one each year and the “biological age,” which is more flexible and changes based on health status. By studying biological signs within the body, scientists can determine a person’s biological age.

In a study of 5,678 people, researchers at Stanford Medicine determined the biological age of their organs by analyzing proteins in the blood, revealing that if a person’s organs are older than others of the same age, they are at a higher risk of disease.

Each organ in our body dies at a different rate, with certain proteins in the blood associated with specific organs. Scientists developed a machine learning algorithm using protein combinations to predict a person’s biological age and verified its accuracy on 4,000 people.

The study focused on the biological age of 11 important organs and revealed that people with rapidly aging organs are at a higher risk of disease and mortality. The research team hopes to replicate these findings in a larger group of people to detect which organs are aging at an accelerated rate, allowing for early treatment.
