Archaeologists unveil 3,500-year-old city in Peru
The 3,500-year-old city, named Peñico, is believed to have served as a key trading hub connecting early Pacific coast communities with those living in the Andes mountains and Amazon basin.
Located some 200km north of Lima, the site lies about 600 metres (1,970 feet) above sea level and is thought to have been founded between 1,800 and 1,500 BC - around the same time that early civilisations were flourishing in the Middle East and Asia.
Researchers say the discovery sheds light on what became of the Americas' oldest civilisation, the Caral.
Drone footage released by researchers shows a circular structure on a hillside terrace at the city's centre, surrounded by the remains of stone and mud buildings.
Eight years of research at the site unearthed 18 structures, including ceremonial temples and residential complexes.
In buildings at the site, researchers discovered ceremonial objects, clay sculptures of human and animal figures and necklaces made from beads and seashells.
Peñico is situated close to where Caral, recognised as the oldest known civilisation in the Americas, was established 5,000 years ago at around 3,000 BC in the Supe valley of Peru.
Caral features 32 monuments, including large pyramid structures, sophisticated irrigation agriculture and urban settlements. It is believed to have developed in isolation to other comparative early civilisations in India, Egypt, Sumeria and China.
Dr Ruth Shady, the archaeologist who led the recent research into Peñico and the excavation of Caral in the 1990s, said that the discovery was important for understanding what became of the Caral civilisation after it was decimated by climate change.
The Peñico community was "situated in a strategic location for trade, for exchange with societies from the coast, the highlands and the jungle", Dr Shady told the Reuters news agency.
At a news conference unveiling the findings on Thursday, archaeologist Marco Machacuay, a researcher with the Ministry of Culture, said that Peñico's significance lies in it being a continuation of the Caral society.
Peru is home to many of the Americas' most significant archaeological discoveries, including the Inca citadel of Machu Picchu in the Andes and the mysterious Nazca Lines etched into the desert along the central coast.

Researchers make concerning discovery embedded in tissue of staple fish — here's what you need to know
A new study has made a concerning discovery in one of Bangladesh's favorite fish. Researchers found that hilsa — a staple in kitchens across the country — is contaminated with not only toxic heavy metals but also dangerous levels of plastic embedded in its muscle tissue, liver, and intestines. As reported by The Daily Star, hilsa fish have been found to contain microplastics — tiny pieces of plastic smaller than 5 millimeters — along with cadmium, lead, mercury, and arsenic. These particles come from plastic bags, bottles, synthetic fabrics, and other items that wash into rivers and oceans. Plastic production in Bangladesh increased by 169% between 2005 and 2014, which is significantly higher than the global average of 25%. Researchers estimated that the Ganges and its tributaries may be dumping up to 30 billion microplastic particles into the Bay of Bengal every day. Hilsa and other animals ingest these particles, which then enter the food chain and our bodies. And it's not just hilsa. A 2022 study found that 17 fish species and three types of shellfish from another area were also contaminated. That means an adult eating just 300 grams of fish a week could end up ingesting over 74,000 microplastic particles a year. This raises serious public health concerns for the millions of people who eat this fish every week. Microplastics have been linked to health problems such as inflammation, hormonal disruption, and potentially cancer. Contaminating such a common food source could harm the long-term well-being of the public. Plus, many contaminated areas are also economically dependent on fishing. As fish become more polluted, communities may see their livelihoods affected, meaning more families could end up struggling financially. Microplastics also harm wildlife and disturb ecosystems, which has a ripple effect across the food chain. Even though Bangladesh has a ban on single-use plastics, it's not always enforced. Plastic bags are still used, and waste continues to end up in rivers from both industrial sources and households. There are calls for the Bangladesh government to strengthen enforcement, raise awareness about plastic pollution, and make affordable alternatives available to the public. This isn't the first time researchers have raised red flags about toxic fish. Similar discoveries have been made in the U.S. and Europe, and efforts to curb plastic production are gaining steam around the world. But with plastic production still rising, experts agree that we need to act now before more of our food becomes contaminated. Environmental groups also help with ocean cleanups to remove plastic waste before it breaks down. Everyday people can do their part by using less plastic — from ditching plastic bags and bottles to supporting refillable product systems. Do you think America has a plastic waste problem?

Archaeologist Says He's Found Atlantis in Groundbreaking Discovery
An archaeologist says he's found the lost city of Atlantis in what would obviously be a groundbreaking find. The claim was made by archaeologist Michael Donnellan at the Cosmic Summit 2025 conference, according to Diario AS. He also played a documentary at the summit "featuring images obtained through underwater technology," the site reported. He repeats the claim in the trailer for that documentary. However, notes that scholars aren't sure whether Atlantis was a myth or real; over the years, other theories have pegged it as being at different locations, including Santorini, Greece. According to Diario AS, Donnellan claims "he has identified three submerged concentric walls carved into the seabed," and that "the dimensions and layout match the city described by Plato in the dialogues Timaeus and Critias," describing Atlantis. Donnellan claims he discovered Atlantis two miles off the coast of Cadiz, Spain, according to LADBible. "If anyone had told me six years ago that I would go in search of Atlantis, I would have said they were crazy," Donnellan says in a documentary trailer that he posted on Instagram. "And yet, here we are. Knowing what we know; not a myth. Not a legend. Atlantis was real. The lost empire Plato described in such precise detail. It actually existed. I have seen these structures with my own eyes. I have touched them with my own hands. These years of field research are about to write a whole new chapter in human history. They will help resolve those eternal questions of where we came from." Cosmic Summit 2025 describes itself as a "live, four-day event where truth-seekers from 14 different countries and 45 U.S. states came together to learn from each other, having life changing conversations, party and laugh together and challenge what we think we know about human history, earth history, science, and the hidden patterns shaping our world." Other theories have the lost city located in Santorini, North Africa, or Sweden, according to LADBible. Some scholars don't believe Atlantis ever existed, the site also noted. 'It matches everything Plato says verbatim,' Donnellan said of the structures he found underwater, according to LADBible. 'He says it came from outside the straits in the region known by the Greeks, 2,400 years ago, as Gades. We know that perfectly well to this day that Gades is the modern-day Cádiz, which happens to be the oldest city in western Europe.' LADBible noted that the structure discovered by Donnellan also has "carved canals and a rectangular ruin in the middle." According to Atlantis was "a likely mythical island nation mentioned in Plato's dialogues Timaeus and Critias" that "has been an object of fascination among western philosophers and historians for nearly 2,400 years. Plato (c.424–328 B.C.) describes it as a powerful and advanced kingdom that sank, in a night and a day, into the ocean around 9,600 B.C." That site says ancient Greeks were divided as to whether Atlantis was "history or metaphor." According to Plato described Atlantis as having an advanced culture and "an island larger than Libya and Asia Minor put together, located in the Atlantic just beyond the Pillars of Hercules—generally assumed to mean the Strait of Gibraltar."Archaeologist Says He's Found Atlantis in Groundbreaking Discovery first appeared on Men's Journal on Jul 12, 2025

Researchers Discover Possible Secret to Better Memory
The secret to a better memory might be tied to your emotions. This is according to a study done by the Hangzhou Normal University in China that was published in the Journal of Neuroscience. The study included 44 university students who were shown 144 squiggly shapes, each of which were followed by a positive, neutral or negative image. Then, the process was repeated two more times for each student. After a 24-hour break, students were given a recognition memory test and the results revealed that students had better recall of the squiggly shapes that were followed by positive images. "Our findings revealed that positive emotions enhanced the retrieval of meaningless squiggles compared to negative emotions," the study said. "These results provide neural evidence for the enhanced memory performance of items associated with positive emotions and shed light on the mechanisms underlying memory formation in emotional contexts," researchers concluded. Researchers did see a similar level of increased brain activity for negative emotions as compared to positive ones, but that did not lead to better recall. The belief is that could be a result of heightened alertness for potential threats due to negative emotions. While a small study, this does lend to the idea that being positive helps in retaining information. Just something to keep in mind if you want to improve your Discover Possible Secret to Better Memory first appeared on Men's Journal on Jul 12, 2025
