Scientists discover 140000-year-old lost city in..., its history will leave you in fear
Scientists around the world are constantly exploring the mysteries of the past, and a recent discovery near Indonesia's Java Island has revealed something fascinating. Over 6,000 fossils have been recovered from the ocean floor, including bones of the extinct human ancestor species, Homo erectus. This discovery suggests that there was an unknown population of Homo erectus living in Southeast Asia, possibly interacting with early modern humans.
What makes this find even more unique is that it's the first time fossils have been unearthed from the sunken parts of the Indonesian archipelago. Around 140,000 years ago, sea levels were much lower, and islands like Java were connected to the Asian mainland through a region known as Sundaland. This region was rich with grasslands, rivers, and wildlife.
Newly found fossils show that those rivers were home to fish, turtles, river sharks, and even hippos. On land, elephants, buffaloes, and a now-extinct elephant-like animal called stegodon roamed the area. Homo erectus likely lived and hunted in these fertile lands, particularly between Java and Madura islands, an area now submerged and known as the Madura Strait.
Some of the fossils bear cut marks, indicating that early human relatives in this region hunted turtles and large animals. These marks provide the oldest known evidence of turtle hunting in Southeast Asia. Fossil clues also suggest that these early hominins hunted animals similar to modern cows.
Interestingly, this type of hunting was more common among early modern humans living on the Asian mainland. This raises the possibility that Homo erectus may have learned these techniques from other human species they came into contact with. Who Were the Homo Erectus?
Homo erectus holds a very important place in the story of human evolution. This ancient species appeared around 2 million years ago and was the first of our ancestors to have a body structure similar to modern humans. They were also the first human species to leave Africa and travel all the way to Southeast Asia.
Along the way, other ancient human species like the Neanderthals and Denisovans also appeared in different parts of the world, including parts of Asia. However, scientists still don't know for sure how much interaction happened between these different species.
According to research, Homo erectus lived on the Indonesian island of Java until about 117,000 to 108,000 years ago, after which they went extinct. Much later, around 77,000 years ago, our own species Homo sapiens arrived in Southeast Asia.

Did UV rays doom Neanderthals?

What happened to the Neanderthals? Our ancestral cousins went mysteriously extinct around 40,000 years ago, while humans did not. The demise of one and survival of the other continues to flummox paleoanthropologists—but some researchers now think sunscreen and tailored clothing might have played a role. Around the time Neanderthals bit the dust, a weakening of the Earth's magnetic field resulted in exposure to higher doses of harmful ultraviolet radiation. Clothing would have offered some protection. Both groups wore animal skins, but evidence suggests Neanderthals tended to wear loosefitting cloaks, while Homo sapiens sewed form-fitting garments. Humans also coated themselves with mineral pigments, which would have functioned as an ancient SPF. It is unlikely that these differences in behavior alone would have resulted in the Neanderthals' demise, but researchers think that their exposure to increased radiation would have had detrimental effects. The increased exposure occurred when Earth's north and south magnetic poles began to wander from their traditional positions. The rotation of the planet and its molten core help generate a protective magnetic field that keeps our planet's ozone layer robust and protects us from high-energy particles that constantly flow from the sun. The field is anchored at the poles, where magnetic forces are most concentrated. But small changes in the core can cause the poles to wander. During the twilight of the Neanderthals, such a wandering caused the magnetic field to drop to about 10% of its average strength. Scientists call this the Laschamps event. To test the effects of the Laschamps, Agnit Mukhopadhyay, a University of Michigan space scientist, and his group created 3-D models of what Earth's magnetic field would have looked like during the event. The results, published in the journal Science Advances, showed where the magnetic field was compromised, allowing radiation and particles to slip through. Researchers know the magnetic field went haywire way back then by examining minerals smaller than the width of a human hair found within ancient deep-sea sediments and volcanic rocks. These tiny grains, which contain iron, become magnetized, and their alignment offers clues about the state of Earth's magnetic field at the time. The researchers' analysis suggests Earth's northern and southern latitudes up to 40 degrees would have been disproportionately affected by the weakening. This area in the Northern Hemisphere—including what is today Spain—is where many Neanderthal and Homo sapiens populations lived. 'As an anthropologist, I was intrigued, because I think a lot about how climate and weather might have affected Homo sapiens and other species, but I never thought about space," said Raven Garvey, a professor of anthropology at the University of Michigan and Mukhopadhyay's co-author. For about a millennium or two, during the Laschamps event, Earth would have experienced higher levels of invisible, cosmic radiation. But the impact of a thinner ozone layer wasn't just about increased radiation exposure. It also would have affected cloud cover, wind belts, rainfall and general weather patterns. 'It's not that the UV kills everybody," said Alan Cooper, an evolutionary biologist at Charles Sturt University in Australia who wasn't involved in the recent work but has published research with similar conclusions. 'It's climate change. Everything goes completely wild at that point." Not only did Neanderthals disappear from the fossil record around this time, Cooper added, but so did other species across the disproportionately affected areas. Mukhopadhyay's group suggested two theories of what helped Homo sapiens, who interbred with Neanderthals, to survive: the use of a primitive kind of sunscreen known as ocher—a naturally occurring pigment composed of iron oxide often used for cave art—to protect their bodies from the sun, and clothing that hugged the body and covered more skin. Right around the time of the Laschamps event, there was an uptick in cave art at sites archaeologists have linked to Homo sapiens, according to Cooper. Anthropologists hypothesize that Homo sapiens also used ocher on their skin based on the fact that populations living in Africa and Australia today apply the pigment as a skin protectant, said Andrew Zipkin, an archaeological scientist affiliated with Arizona State University who wasn't involved in the recent study. Archaeological sites linked to Neanderthals and modern humans have both yielded stone tools called scrapers used for processing animal hides to make them supple and wearable, Garvey said. But researchers have found evidence of a broader clothing-making tool kit at Homo sapiens-related sites. 'We're also seeing things like needles and awls and the kinds of implements that would be very useful to poke holes in these hides and then stitch them together with sinew in the mass production of tailored clothing," she added. Anthropologists are careful to note that the coincident timing of the Neanderthal extinction and the Laschamps event could have been mere chance. Differences in population sizes and other things could also have made the species's survival less likely, according to Tony Capra, a University of California, San Francisco evolutionary geneticist who wasn't involved in the work. The goal of the recent work, according to the study authors, was to focus on one aspect of a multifaceted mystery. 'Whoever had the tailored clothing probably did have this advantage," Garvey said. 'But was it exclusive to one group and was it enough to lead to the extinction of one and the proliferation of the other? These are million-dollar questions." Write to Aylin Woodward at

Radioactive horns: South Africa's bold approach to rhino conservation

In a world-first effort to combat the ruthless poaching of rhinos, scientists in South Africa have developed a groundbreaking method: injecting rhino horns with radioactive material. The initiative, known as the Rhisotope Project, is the brainchild of researchers from the University of the Witwatersrand (Wits University) and marks a bold, science-driven attempt to save one of Africa's most iconic animals. South Africa is home to the largest population of rhinos in the world—particularly white rhinos and the critically endangered black rhinos. Yet, this very distinction has turned the country into a poaching hotspot. According to conservation charity Save the Rhino , over 400 rhinos have been poached in South Africa every year since 2021, driven by illegal trade networks that stretch from African parks to Asian markets. Read more: After humans, this mammal rules the Earth, and 5 countries with its thriving population (no, not cows!) Rhino horns are highly sought after in parts of Asia, where they are believed to have medicinal properties and are also viewed as luxury status symbols. The lucrative black market has made it difficult for governments and conservationists to keep pace. A radioactive breakthrough Enter the Rhisotope Project, a six-year research effort that cost roughly £220,000 ($290,000) and involved collaboration with the International Atomic Energy Agency (IAEA). The method involves injecting a tiny amount of radioactive isotope into a rhino's horn, a process that has been rigorously tested and deemed completely safe for the animals. Wits University professor James Larkin, one of the key figures behind the project, told the BBC that the innovation shifts the approach from reactive to proactive. 'At least one animal a day is still being poached,' he said. 'This is a significant tool to help reduce the numbers of poaching.' The idea is not to harm anyone who touches the horn but to make the horn detectable by radiation monitors at ports, airports, and border crossings. Customs officers, who already use radiation detectors for other security purposes, could easily identify smuggled rhino horns—even those hidden inside massive 40-foot shipping containers. Pilot study The initial pilot involved 20 rhinos, all of whom responded well to the treatment. Larkin confirmed the material was 'completely safe' and did not harm the animals. The team's success in proving that the radioactive horns can be tracked through international freight systems marks a pivotal moment in the fight against wildlife trafficking. Jessica Babich, head of the Rhisotope Project, emphasized the scale of their ambition: 'Our goal is to deploy the Rhisotope technology at scale to help protect one of Africa's most iconic and threatened species. By doing so, we safeguard not just rhinos but a vital part of our natural heritage.' Read more: 5 snake parks in India that are absolutely fang-tastic and what makes them special Conservationist Jamie Joseph, director of Saving the Wild , called the project 'innovative and much needed.' She noted that while this solution isn't the 'endgame,' it can still disrupt smuggling networks and help experts better understand trafficking routes through hard data. 'It will certainly help disrupt the flow of horns leaving the country and help experts better map out the illegal channels by providing reliable data,' she added. Despite its promise, the Rhisotope Project is not a silver bullet. Activists and scientists alike stress the need for stronger laws, enforcement, and political will. Without these structural changes, even the most advanced technologies may only offer short-term deterrence. Still, the Rhisotope Project represents a rare intersection of nuclear science, conservation, and real-world impact—an example of how innovation can step into spaces where policy and enforcement have lagged. As poachers use more sophisticated tools, so tools used to fight them are also being enhanced.

5 common mistakes that attract mosquitoes to you

They may be tiny, but mosquitoes are considered the deadliest animals on Earth, responsible for spreading diseases like malaria, dengue, Zika, and yellow fever. According to the World Mosquito Program, these buzzing bloodsuckers contribute to over one million deaths every year, making it worth understanding what draws them in. Not considering your blood type Some blood types are more attractive to mosquitoes than others — and unfortunately, this isn't something you can control. In a 2022 study , researchers found that different mosquito species show distinct preferences: Type O: Highly attractive to the Asian tiger mosquito ( Aedes albopictus ) Type AB: A favorite of the marsh mosquito ( Anopheles gambiae ) Even more interesting : around 80% of people naturally secrete a substance through their skin that reveals their blood type. If you're a "secretor," you're more likely to get bitten — regardless of your actual blood group. Producing more carbon dioxide Mosquitoes have a strong sense for carbon dioxide, and they can detect it from over 100 feet away. That's bad news if you breathe heavily, talk a lot outdoors, and sleep with your mouth open. Because CO₂ is exhaled through your nose and mouth, mosquitoes are often drawn to your head and face first. That constant buzzing near your ear? Not your imagination. Letting sweat and skin bacteria build up Mosquitoes don't just smell sweat; they analyze it. Your skin produces several chemical cues that they love- lactic acid and ammonia in sweat, bacteria that mix with sweat to form unique body odors, and carboxylic acids, or fatty acids, which one study found in higher concentrations in people most prone to bites. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like They Were So Beautiful Before; Now Look At Them; Number 10 Will Shock You Cash Roadster Undo Overlooking Factors Like Pregnancy and Alcohol Certain conditions can amplify your mosquito appeal. One such is pregnancy. A 2000 study in Africa found that pregnant women attracted twice as many mosquitoes as non-pregnant women. This was linked to increased carbon dioxide output and higher body temperature during late pregnancy. Another is beer. Even a single bottle can make a difference. In one study, participants who drank a liter of beer attracted significantly more mosquitoes than those who drank water. The reason isn't fully understood, but it may be due to alcohol's effect on body chemistry and temperature. Wearing the wrong clothes and eating the wrong foods Clothing and diet also matter. Mosquitoes are visual hunters, and they're drawn more to dark colors like green and black than to lighter shades such as white or gray. As for food, while evidence is still emerging, one study from the University of Wisconsin found that eating bananas increased mosquito contact. Folk wisdom also points to salty, sweet, spicy, or potassium-rich foods as potential culprits, but the banana link is one of the few backed by research.
