Pics: Two shipwrecks confirmed as slave ships by archaeologists

Archaeologists from the National Museum of Denmark recently announced that two 18th-century shipwrecks off the coast of Central America were confirmed to be slave ships.
According to Fox News, the remains of the two ships, known as the Fridericus Quartus and Christianus Quintus, have been located underwater off the coast of the Cahuita National Park in Costa Rica for more than 300 years. The outlet noted that the two ships were believed to have been pirate ships prior to a recent discovery.
Fox News reported that David John Gregory, an archaeologist with the National Museum of Denmark, told the outlet that the ships are now believed to have been carrying between 600 and 700 African slaves and roughly 100 crew members when the ships sank.
'When the ships were abandoned on the coast of present-day Costa Rica, almost all of the enslaved were released on the forested coast except for about 20 people, who were forced onboard smaller vessels heading for the nearby Spanish town of Portobello,' Gregory said. '[Fridericus Quartus] was set on fire by its crew, while the other, Christianus Quintus, was set free from its moorings and soon after stranded on the coast.'
The National Museum of Denmark announced last month that new information regarding the Fridericus Quartus and Christianus Quintus had been revealed by 'scientific analyses from an underwater excavation in 2023, when marine archaeologists from the National Museum of Denmark and the Viking Ship Museum took samples of wood from one of the wrecks and from the bricks that were part of the cargo more than 300 years ago.'

Gregory told Fox News that the excavation was 'minimal' and that his team surveyed approximately 21 square feet around one of the ships to 'obtain samples of the ship's timber.'
According to the National Museum of Denmark, archaeologists have been able to use dendrochronological technology to determine that the wood from the ships was from the 17th century.
The National Museum of Denmark explained, 'The timbers originate in the western part of the Baltic Sea, an area that encompasses the northeastern German province of Mecklenburg, as well as Schleswig-Holstein, Denmark and Scania — and that the tree was cut down sometime during the years 1690-1695.'
The museum added that the 'charred and sooty' wood confirmed historical sources that claimed one of the ships had been 'set ablaze.'
'The analyses are very convincing and we no longer have any doubts that these are the wrecks of the two Danish slave ships,' Gregory said. 'The bricks are Danish and the same goes for the timbers, which are additionally charred and sooty from a fire. This fits perfectly with the historical accounts stating that one of the ships burnt.'
Pictures of the remains of the two Danish slave ships have been shared on X, formerly Twitter.

Exclusive: We Thought Having a Baby Was 'Impossible.' Then Doctors Used AI

Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. The parents of the world's first baby born thanks to AI exclusively told Newsweek how a new IVF procedure powered entirely by artificial intelligence made the "impossible" a reality. The couple's hopes of starting a family were crushed when Edna, 42, and Tony, 45, were diagnosed with infertility issues, including Edna's ovarian insufficiency. But in 2023, they were introduced to a prototype study led by Conceivable Life Sciences through Hope IVF—a private clinic in Mexico City. From left to right: Luis, Dr Luis Miguel Campos (the patients' clinician), parents Edna and Tony. From left to right: Luis, Dr Luis Miguel Campos (the patients' clinician), parents Edna and Tony. Conceivable The precision of AI This study proved it was possible to control robotics within the IVF lab to perform ICSI, otherwise known as Intracytoplasmic Sperm Injection, remotely to create an embryo. This means embryos created through the robotic ICSI step receive consistent treatment with high precision and a more controlled approach to combining the egg and sperm, compared to current manual methods. The surgeon still oversees the robot and the processes, but with much improved outcomes. Edna and Tony—who are using their middle names for privacy—spoke exclusively to Newsweek about how they became the first family shaped by AI. "We represent expectations and hope for all those couples who are unable to reach their goal to become parents," they said through Spanish translation. "Once we heard the baby's heartbeat, we felt like we reached something that seemed previously impossible." A scalable model for fertility treatment The prototype study involved 41 patients and to date, has resulted in 21 pregnancies and 18 live births. Its system sees AI-powered robots help human doctors in a first step towards automating IVF treatments. The remote ICSI procedure used allows for a much gentler approach to embryo creation, helping improve quality outcomes at a microscopic level. Baby Luis (his real name) was born in Morelia in November 2024. Now seven-months-old, he has become the first baby to be conceived thanks to AI. Inside the AI system Chief medical officer at Conceivable Life Sciences, Dr. Alejandro Chavez-Badiola and one of the principal investigators on the paper, shared two scenarios: "Am I the lucky patient who is going to be treated by the best embryologist in the world at 8 a.m. after a cup of coffee and with a smile on their face, fully focused," he told Newsweek. "Or am I going to be the unlucky patient who is going to be treated by the best embryologist in the world at 1 p.m. when they're about to inject their 17th egg, thinking about lunch and having just received a distressing phone call from their partner." With this new system, the entire procedure uses mathematical algorithms and robotics to carry out the fertilization process step-by-step, with future precision likely to be beyond human capability. "Automation is not only allowing us to standardize these issues with the precision of robots, but to scale this [and] to make sure that every patient anywhere in the world, at any given time, can be treated by the best embryologists," Dr. Chavez-Badiola said. Remote ICSI photography. Remote ICSI photography. Conceivable Tony told Newsweek that the couple didn't have concerns about using the technology to finally become parents. "Although it can be directed to other purposes like weapons or other negative aspects, I feel like it should be applied on a daily basis, because well done, its purpose will be at the service of mankind," he said. While there will always be a clinical team overseeing the automated lab, remote control enables global teams to manage automated labs beyond regular hours, allowing for 18–20-hour workdays. Additionally, as the system can be operated remotely, a specialist in one country can carry out fertilization procedures for patients in another. Cost and duration were also differing factors from traditional methods, but the couple put their trust in the team at Conceivable. "By being more optimal and efficient, I feel like it will reduce the amount of attempts and the necessity of medications," Edna told Newsweek. Edna said that the process was fraught with emotion, given the negative outcomes of their previous IVF rounds. Edna was working in another city when she took the pregnancy test. "When I told Tony the news I was pregnant, it was a delightful surprise for him," she told Newsweek. "We were very happy." Luis, the first baby born from remote ICSI.

However, in their trials, the researchers also found that embryos created using this AI system had an as good—if not better—development potential than those made by humans alone, resulting in high-quality blastocysts—the stage at which embryos are typically relocated from an embryo transfer catheter to the uterus. Edna and Tony's clinician Dr. Luis Miguel Campos told Newsweek that once he had explained the process of ICSI to them, they saw it as an opportunity. "I joined this program to help two beautiful humans achieve their when they heard they were pregnant, I cried like never before," he said. As for next steps at Conceivable, Dr. Campos said consistency in outcomes is a top priority, eventually leading to an improvement in access for any patient around the world. "By [producing] consistency in results, the control process will imply reducing costs and be more efficient," he said. Ethics and AI Dr. Alexander Kotlyar, a reproductive endocrinologist and infertility specialist at Genesis Fertility, told Newsweek emerging AI tools in fertility can enhance core ethical principles, provided they are carefully assessed and properly trained. "The ethical debate around AI reminds me of the long-standing tug-of-war behind genetic testing of embryos," he said. "In both cases, there is concern about how the use of new technology, like DNA testing techniques, can truly benefit patient outcomes, [for example], getting pregnant and having a live birth." Dr. Kotlyar explained the use of AI in the fertility field has grown significantly since the first "test tube" baby was born over forty years ago. This development can be partly attributed to the fact that the processes behind AI algorithms are often not transparent, which raises questions about their outcomes and reliability. "This concern is even more profound with AI since decision-making is, at least partly, given to a machine," he told Newsweek. "However, I would reassure patients and the public that in both cases, the technology is always tested against the principles of core medical ethics and if we cannot stay true to those principles, then we do not use the technology." Hope for future parents For Edna and Tony, being the first successful participants of the prototype clinical trial is a dream come true. "We were fortunate to be selected over other candidates for this first treatment, and we feel blessed," they told Newsweek. "We encourage all those couples who are on the journey to becoming parents to not abandon their dreams and hopes." The couple received strong support from both sides of their families. "Some of them felt a little concerned but in the end, everyone was really happy for our outcome," Tony said. When he's old enough, both Edna and Tony will happily tell Luis that he was conceived using AI. "There's a lot of ignorance and certain concerns about technology, but we will explain gladly to our son." ‌Do you have a tip on a health story that Newsweek should be covering?

Video does not show astronaut exposing 'fake' life in space

"Former Astronaut Karen Nyberg Shows How NASA Fakes Space Flights.." a June 16, 2025 post on X claimed. It shares a video of a woman in front of a space station-like backdrop watching a chip bag float away from her, side-by-side with the same footage being filmed in front of a green screen. A person in a green body suit is manipulating the bag. The video garnered thousands of interactions in posts on X, Threads, Instagram and Facebook. The clip also circulated in posts making similar claims about Nyberg in French, Spanish and Italian. Nyberg is a retired NASA astronaut who completed two spaceflights during her career, including a 166-day stay on the ISS in 2013 (archived here). But she is not the woman in the green screen video. Comments on the post on X included links to previous debunks from USA Today and PolitiFact who named the woman in the video as Paige Windle. In the clip, a person off-camera is heard calling the woman Paige. Windle is the founder of a lifestyle management company and the wife of David Weiss, known online as "Flat Earth Dave," the host of "The Flat Earth Podcast." Contacted by AFP, Weiss confirmed Windle is the one on-camera. "This video never dies. It keeps coming back," Weiss said in a June 17 email. The video was originally posted on Weiss's YouTube channel as part of a series titled "Globebusters," but made no mention of Nyberg (archived here). "Someone took that clip and presented it as Karen Nyberg and it went viral a bunch of times and now it has started again," he said. He said he has repeatedly addressed the false use of the video, sharing with AFP the cover image of a YouTube video he posted in response to the false viral claims (archived here). Astronauts onboard the ISS experience microgravity, causing them and objects to float (archived here). At the altitude of the ISS, gravity is 90 percent of the total gravity one feels on Earth, but an absence of air resistance causes all objects in the ISS to fall at the same rate, producing a weightless appearance. The ISS stays afloat because it moves at a speed that matches the curve of the Earth, causing it to "fall around" the planet while staying at roughly the same altitude. The moon's orbit works in a similar way. NASA uses the ISS in part to study how extended time periods in microgravity and other conditions in space impact the human body as it prepares for future long-term missions in space. On her website, Nyberg features a video she recorded on the ISS where she worked on a quilt (archived here). Unlike in the video filmed in front of the green screen, Nyberg's hair and necklace float throughout the clip due to the microgravity conditions. AFP reached out to Nyberg's representative for comment, but a response was not forthcoming. AFP has previously debunked claims that ISS astronauts faked a video from the station.
