The recent discoveries of two rare deep-sea dwelling oarfish have sparked fears of a looming natural disaster.
The fish were discovered in separate incidents in India and Tasmania within the last week.
In the first incident, fishermen in Tamil Nadu, India, pulled a 30-foot oarfish from the water. The massive fish required seven men to hold it for the video.

On June 2, a dogwalker named Sybil Robertson encountered a dead nine-foot specimen washed up on a Tasmanian beach and posted photos to a citizen scientist group on social media.
"I just knew it was something unusual and weird," Sybil Robertson told The Daily Mail, describing the oarfish's markings as "fabulous".
A 'Doomsday' Fish?
Oarfish are sometimes known as "doomsday fish"—a reputation that stems from interpretations of the oarfish in Japanese folklore.
As per Forbes, at least a dozen oarfish washed up onto Japan's coastline in the year before the 2011 Fukushima earthquake and tsunami, which brought the deep-sea creatures back to the forefront of the imagination.

Ben Fraber, an ichthyologist and the marine vertebrate collection manager at Scripps Institution of Oceanography in San Diego, told Newsweek in a phone interview that the mythology was "compelling enough" to capture the public's attention.
"You do see when there's a big change in pressure on land, birds and other animals will move out of the way," Fraber said.
However, researchers in Japan took a closer look at the phenomenon, bringing in data points that included beached whales and anglerfish, as well as known natural disasters and earthquakes dating back to the early 1900s.
"They found almost no correlation whatsoever," Fraber noted. "It's really interesting to think about, but it doesn't seem to have a statistical link that we can find."
A Rare Find
Fraber has seen oarfish in person—last year, two oarfish were discovered by employees of Scripps Institution of Oceanography who were out snorkeling for the day.
The employees notified lifeguards, and the institute was able to work with the National Oceanic and Atmospheric Administration (NOAA) to bring the oarfish in.
Fraber preserved the fish in formaldehyde and alcohol, and members of the public can see one of them currently in the Birch Aquarium at Scripps in San Diego.
Fraber said oarfish sightings are relatively rare in Southern California—the two his team encountered were only the 21st and 22nd discovered since 1901.
"Having the samples in person instead of just a video allows us to look at their stomach contents, look at their genetics, we'll get nitrogen and carbon isotopes that can tell us where they are in the open ocean food web," Fraber said.
"And we preserve them so people in the future can continue asking questions from them."
According to Fraber, oarfish are filter feeders whose jaws are modified so they can push them forward and vacuum water in, creating suction that traps food similar to bass or large whales.
Oarfish primarily eat krill and small fish, which may be confused by the oarfish's silvery body that refracts light.
"You're a little school of fish, you're swimming around, you see this thing, but it kind of just looks like a big jelly or gelatinous organism, something you're not too concerned about because a jellyfish is not going to try to eat you," Fraber said.
"So you swim up and it's actually not that. It's this big fish that has a highly modified mouth that can protrude and create a kind of vacuum cleaner. It slurps up all these fish."
A "Wow" Reaction
Having handled and seen oarfish in person, Fraber understands the hype.
"I think part of it is the size," he said. "Part of it is the look, they have this beautiful bright red fin, big silvery body, large eyes.
"And part of it is the scale. We're not used to seeing animals that big—with the exception of sharks, dolphins and whales—so it elicits this kind of 'wow' reaction."
Fraber noted that the mythology of sea serpents is probably related to misidentified oarfish long ago.
"It's like actually getting to see this semi-mythological thing in person, it's not a myth, it's a real animal that's living with us on our planet, I think that makes it really amazing," he said.
"Even though I've worked on fish for almost 20 years, and have handled many oarfish specimens, these two last year were the first time I actually got to see them fresh and unpreserved in person, and it was pretty magical."

Japan launches third rocket to measure climate change

A Falcon 9 with Dragon Spacecraft carrying NASA's SpaceX Crew-10 Mission lifts off from Launch Complex 39A at Kennedy Space Center in Florida, in partnership with Japan Aerospace Exploration Agency in March. File photo by Pat Benic/UPI | License Photo June 29 (UPI) -- A Japanese company has launched a rocket designed to monitor sea temperature and greenhouse gases as part of its overall mission to study the effects of climate change on the atmosphere. The Japanese Aerospace Exploration Company launched its 50th and final H-2A rocket mission, sending the GOSAT-GW into orbit from the Yoshinobu Launch Complex at the Tanegashima Space Center in Japan on Sunday. This is the third GOSAT mission to study the effects of climate change on ocean temperatures and fossil fuel and other greenhouse gases and their effect on the planet's ecosystems. The Sunday mission joins the previous flights already in orbit, GCOM-W2, which launched in 2012, known as "SHIZIKU," and GOSAT-1, known as "IBUKI," which was deployed in 2009. Among other instruments, GOSAT-GW is carrying a spectrometer named TANSO to aid in measuring the effects of greenhouse-related climate change. "The obtained data will be used to monitor water vapor profiles, sea ice, and soil water content," the GOSAT website said. Other instruments will monitor sunlight reflection during daylight hours and target and other large emission sources such as power loans and oil and gas facilities.

Higher Risk of Miscarriage in IVF When Father Is Elder Millennial

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. Paternal age plays a critical role in IVF success—even when using eggs from young, healthy donors—a study has found. At the 41st ESHRE Annual Meeting, researchers reported that male partners over 45 have higher miscarriage risks and lower live birth chances during IVF with donor eggs. The research, spanning 1,712 donor egg IVF cycles conducted between 2019–2023 in Italy and Spain, aimed to isolate the impact of paternal age by controlling for maternal variables.

Doctor providing compassionate healthcare consultation while young couple patient holding hand, comfort each other after infertile report. Moment Makers Group All cycles involved fresh oocytes (immature eggs found in the ovaries) from young donors (average age 26.1), frozen sperm from male partners and a single blastocyst embryo transfer. The average age of female recipients was 43.3. When results were analyzed, stark differences emerged between the two paternal age groups: Miscarriage rates were 23.8 percent among couples with male partners over 45, compared to 16.3 percent in those with younger male partners. "It was genuinely surprising to see how strongly paternal age affects miscarriage and live birth rates, even in oocyte donation programs," lead author and embryologist Maria Cristina Guglielmo of Eugin Italy told Newsweek. Live birth rates dropped to 35.1 percent in the older paternal group, versus 41 percent for those aged 45 or younger. "This challenges the common perception that maternal factors are the primary drivers of reproductive success and highlights the need to pay more attention to paternal factors in fertility," said Guglielmo. She explained that biological changes in sperm linked to aging—such as increased DNA mutations, abnormal chromosome counts, DNA fragmentation and altered epigenetics—can compromise embryo development and raise miscarriage risk. "Together, these factors affect both the genetic integrity and the functional quality of sperm, which can impair embryo development and contribute to a higher risk of miscarriage," she added. Importantly, the study only included first embryo transfers and excluded repeat cycles, allowing for a clearer comparison. According to Guglielmo, this strengthens the evidence that paternal age is not just a minor variable, but a significant factor in reproductive outcomes. "Our hypothesis is that time does not change the ability of sperm to produce embryos however, some genetic defects in sperm only become apparent later in the process, potentially leading to adverse effects on embryo development and contributing to negative selection outcomes in the fetus," she said. For couples who are considering starting a family later on in life via IVF, Guglielmo advises to consult with a fertility specialist early to understand how paternal age might affect chances and explore all the available options. "All women know how the miscarriage is associated to mother age; however, it's time to inform the couple about how the father age is also important, especially during the pregnancy, in order to evaluate a prenatal screening," she said. "Being well-informed and proactive can help couples make the best decisions for their family-building journey and improve their chances of achieving a successful and healthy live birth."

Ex-NASA Chief Sounds Alarm Over Space Agency's Future

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 former head of NASA has said that the space agency is "being savaged," in response to proposed cuts by the Trump administration. Bill Nelson, NASA administrator from 2021 to 2025, said: "If they continue on the path that they're on, it will be a crippled agency." NASA has been working on plans to bring astronauts back to the moon for the first time since 1972 with the Artemis program, and to build the Lunar Gateway space station on the moon for long-term lunar scientific exploration. These plans are now on hold amid a proposed Republican budget that would cut as much as half of NASA's science funding. President Donald Trump's budget request to NASA, which must be debated by Congress before October 1, called for the agency to "terminate unaffordable missions," cut "woke" education programs and implement a "more sustainable, cost-effective approach to lunar exploration." Overall, the budget proposes reducing the agency's annual budget from $24.9 billion to $18.8 billion. Newsweek has contacted NASA for comment via email outside of working hours. The Mary W.

Puskar/AP Photo Why It Matters The Trump administration says that the proposed reductions are necessary to rein in excessive spending, eliminate underperforming projects, and reorient NASA toward more cost-efficient private partnerships. The White House has highlighted examples such as the $4 billion-per-launch cost of the Space Launch System, NASA's expendable heavy-lift rocket. Critics say the proposed budget cuts threaten American progress in space and in scientific endeavor more broadly. In parallel, the administration has proposed eliminating climate satellite projects. Previous scientific cuts by the Trump administration include Health Secretary Robert F. Kennedy Jr. firing vaccine advisers from the Department of Health and Human Services (HHS) and a decrease in grants for scientific research. What To Know Cuts to NASA are creating "chaos" and will likely have "significant impacts to our leadership in space," a Democratic House staffer, speaking on condition of anonymity, told The Sunday Times, a U.K. newspaper. NASA's Artemis project was launched during the first Trump administration and has already cost more than $26 billion for the new Space Launch System. Cutting NASA's budget would also heavily impact space science across Europe, as NASA has partnerships with the European Space Agency (ESA), which was collaborating with NASA and Airbus to build part of the new rockets to the moon and a Gateway space station. This collaboration, which has already cost ESA €840 million in Airbus payments and another €650 million in future Airbus contracts, was supposed to result in three European astronauts going on the new lunar mission. The future of this plan is uncertain. Elon Musk's space exploration company SpaceX still works with NASA, including on lunar exploration. However, he left the federal government and has criticized budget cuts amid a rift with Trump. The future of SpaceX's partnership with NASA is now also uncertain. "The easiest way to save money in our Budget, Billions and Billions of Dollars, is to terminate Elon's Governmental Subsidies and Contracts," Trump wrote on Truth Social in June. What People Are Saying Bill Nelson told reporters at a POLITICO summit: "That's like eating our seed corn. We're not going to have anything to plant next year in the quest of trying to understand what is part of the statutes for NASA, which is to search for life, and therefore to understand who we are, what we are, and where we are." Acting NASA Administrator Janet Petro in a statement in May: "This proposal includes investments to simultaneously pursue exploration of the Moon and Mars while still prioritizing critical science and technology research. I appreciate the President's continued support for NASA's mission and look forward to working closely with the administration and Congress to ensure we continue making progress toward achieving the impossible." The White House in a statement in May: "The Budget phases out the grossly expensive and delayed Space Launch System (SLS) rocket and Orion capsule after three flights. SLS alone costs $4 billion per launch and is 140 percent over budget. The Budget funds a program to replace SLS and Orion flights to the Moon with more cost-effective commercial systems that would support more ambitious subsequent lunar missions." Daniel Neuenschwander, ESA director of human and robotic exploration, quoted in The Sunday Times: "We want to work on reducing the risks of the projects where we are dependent on US decisions. We want to increase the projects which are done in autonomy, where we are the masters of the decisions we take." What Happens Next ESA leaders are looking to work on projects that do not rely on American money or American political decision-makers, turning to work with India and Japan, and possibly even China, instead. Senator Ted Cruz, chair of the Senate Commerce Committee which oversees NASA's budget, has supported Artemis in the past, so it is not certain that NASA's budget will be cut by as much as the Trump administration's proposal by the October 1 deadline.
