A chilling alert has emerged from Japan after a major autopsy study found that people who died suddenly of an unexpected cardiac arrest after receiving Covid mRNA booster “vaccines” have tiny “micro-scars” in their hearts.
The study found that the previously undetected scarring was caused by repeated mRNA injections.
Researchers warn that difficult-to-detect damage is responsible for global surges in sudden death in the absence of overt ischemic heart disease.
The peer-reviewed autopsy study was led by Japanese cardiologist Dr. Tomomi Koizumi and pathologists Dr. Masao Ono.
The findings of the study were published in the journal JACC: Case Reports.
Koizumi and Ono investigated the presence of cardiac multiple micro-scars (MMS) in three elderly patients who died of unexplained cardiac arrest.

Health and Human Services Secretary Robert F. Kennedy Jr. announced Tuesday that the COVID-19 vaccine was removed from the recommended immunization schedule for healthy children and pregnant women.
Kennedy was flanked by FDA Commissioner Dr. Marty Makary and National Institutes of Health Director Dr. Jay Bhattacharya when he said he “couldn’t be more pleased to make the announcement.” This comes years after Kennedy founded the Children’s Health Defense, which challenges vaccination among children amid scrutiny of side effects.
“Last year, the Biden administration urged healthy children to get yet another COVID shot despite the lack of any clinical data to support the repeat booster strategy in children,” Kennedy said. “Now we’re one step closer to realizing President Trump’s promise to make America healthy again.”

In brief: Elon Musk puts a lot of faith in Tesla’s Optimus humanoid robot. Not only does the CEO believe it will drive the EV firm’s valuation into the trillions, but he also expects thousands of the bots working at Tesla – and other companies’ – factories. However, the former Optimus team lead thinks these robots aren’t the right fit for high-speed, repetitive factory work.
In August 2021, Tesla announced that it was creating a general-purpose, bipedal, humanoid robot capable of performing tasks that are unsafe, repetitive, or boring for humans to carry out.
The robot has undergone several design changes since then, with improvements in speed, stability, weight, balance, and other areas.
Last year, Musk made the bold claim that there will be at least one humanoid robot for every person in the world and that Tesla will control a massive share of this market, pushing its value to $25 trillion. He later said that the robots would be put to work in Tesla factories helping build its vehicles – presumably lowering costs by replacing human workers.

North Korea, much like China and Russia in recent weeks, issued a scathing rebuke on Tuesday of President Donald Trump‘s pursuit of his Golden Dome missile defense system.
Trump has made the Golden Dome — a comprehensive air defense system that, once operational, will be able to intercept various missiles fired from land, sea, and space — a signature of his military policy early in his second term in office.
North Korea‘s foreign ministry said that Trump’s plan is the “height of self-righteousness, arrogance, high-handed and arbitrary practice, and is an outer space nuclear war scenario supporting the U.S. strategy for uni-polar domination with the preemptive establishment of the outer space-based military substructure, not a ‘defensive measure’ to cope with the ‘threat’ from someone.”
The ministry accused the U.S. of being “hell-bent on the moves to military outer space,” while claiming that the plan for the Golden Dome, as outlined by the Trump administration, “is also the expression of another attempt to militarize outer space coming from the past strategies for dominating outer space and the epitome of revealing the criminal past of the U.S. which plunged the whole world into the nightmare of the outbreak of a nuclear war.”

A massive asteroid named 2025 JR is drawing global attention as it speeds toward Earth for a close encounter. Roughly the size of a 25-storey building, the space rock is set to make its nearest approach on Wednesday, May 28. While it will safely bypass Earth at a distance of 4.6 million kilometers, that proximity is considered unusually close in astronomical terms. The asteroid’s size and speed—combined with its Earth-crossing orbit—have sparked interest among scientists, space agencies, and skywatchers alike. Though there is no risk of collision, the flyby serves as a vivid reminder of how close—and unpredictable—near-Earth objects can be, reinforcing the need for continued monitoring and space preparedness.
On 28 May 2025, Asteroid 2025 JR is set to pass by Earth at 8:40 am IST, which is about 250 feet (76 meters) across, a respectable size in space. It’s an Apollo-class near-Earth object (NEO)—a class marked by asteroids that have orbits that intersect with Earth’s orbit around the Sun. Being of this kind of orbital feature, these asteroids are kept under close watch for how much danger they could pose.The asteroid travels at a staggering 40,800 km/h, a speed that, were it orbiting the Earth, would finish the journey in under an hour. While 2025 JR is not deemed a “potentially hazardous asteroid” because it is below the threshold diameter of 460 feet (140 meters), it is large enough that if it were to strike the Earth, the destruction would be devastating.

The Food and Drug Administration has directed COVID-19 vaccine manufacturers to expand the warning for two forms of inflammation, according to letters made public on May 21.
The FDA told BioNTech, which produces a vaccine with Pfizer, and Moderna to update warnings regarding myocarditis—or heart inflammation—and the related condition pericarditis.
Richard Forshee, acting director of the FDA’s Office of Biostatistics and Pharmacovigilance, said that new information has emerged, including a 2024 FDA study that found some myocarditis patients had signs of heart scarring months after vaccination.
The companies must update labels to state that following administration of the 2023–24 versions, “the highest estimated incidence of myocarditis and/or pericarditis was in males 16 through 25 years of age,” Forshee said. The highest estimated incidence of the post-vaccination inflammation is about 38 cases per million doses for both vaccines, according to the proposed update.
The current warnings say the highest observed risk after Moderna vaccination is in males aged 18 to 24, and after Pfizer-BioNTech vaccination is in males aged 12 to 17.

During a briefing from the Oval Office this week, President Donald Trump revealed his administration’s plan for “Golden Dome”—an ambitious high-tech system meant to shield the U.S. from ballistic, cruise and hypersonic missile attacks launched by foreign adversaries. Flanked by senior officials, including Secretary of Defense Pete Hegseth and the project’s newly selected leader, Gen. Michael Guetlein of the U.S. Space Force, Trump announced that Golden Dome will be completed within three years at a cost of $175 billion.
The program, which was among Trump’s campaign promises, derives its name from the Iron Dome missile defense system of Israel—a nation that’s geographically 400 times smaller than the U.S. Protecting the vastness of the U.S. demands very different capabilities than those of Iron Dome, which has successfully shot down rockets and missiles using ground-based interceptors. Most notably, Trump’s Golden Dome would need to expand into space—making it a successor to the Strategic Defense Initiative (SDI) pursued by the Reagan administration in the 1980s. Better known by the mocking nickname “Star Wars,” SDI sought to neutralize the threat from the Soviet Union’s nuclear-warhead-tipped intercontinental ballistic missiles by using space-based interceptors that could shoot them down midflight. But fearsome technical challenges kept SDI from getting anywhere close to that goal, despite tens of billions of dollars of federal expenditures.

Most of us are familiar sloths, the bear-like animals that hang from trees, live life in the slow lane, take a month to digest a meal and poop just once a week. Their closest living relatives are anteaters and armadillos, and if that seems like an odd pairing, there’s a reason why. Today, there are only two sloth species, but historically, there were dozens of them, including one with a bottle-nosed snout that ate ants and another that likely resembled the ancestors of modern armadillos.
Most of these extinct sloths also didn’t live in trees, because they were too big. The largest sloths, in the genus Megatherium, were about the size of Asian bull elephants and weighed roughly 8,000 pounds.
“They looked like grizzly bears but five times larger,” said Rachel Narducci, collection manager of vertebrate paleontology at the Florida Museum of Natural History.
Narducci is co-author of a new study published in the journal Science in which scientists analyzed ancient DNA and compared more than 400 fossils from 17 natural history museums to figure out how and why extinct sloths got so big.

Contrary to conspiracy theories, the Earth’s core isn’t hollow. The dense, hot ball instead contains a stew of precious metals including platinum, ruthenium, and pretty much all of the planet’s gold. As lucrative as that sounds, there’s essentially no way humanity will ever access this natural treasure chest buried beneath more than 1,850 feet of solid rock. But according to recent discoveries made at volcanoes in Hawai’i, trace amounts of some of those coveted metals are seeping up from the planet’s deepest reaches.
“When the first results came in, we realized that we had literally struck gold,” Nils Messling, a geochemist at Göttingen University, said in a statement. “Our data confirmed that material from the core, including gold and other precious metals, is leaking into Earth’s mantle above.”
Messling and collaborators explained their findings in a study published on May 21 in the journal Nature. The team recently detected trace amounts of the precious metal ruthenium while analyzing volcanic rock samples collected across the islands of Hawai’i. More specifically, they noted the unexpected presence of the ruthenium isotope, ¹⁰⁰Ru.
“Unexpected” is the key word there. While ¹⁰⁰Ru does exist in Earth’s mantle, it’s slightly more abundant inside of the core—alongside 99.999 percent of the planet’s gold and other precious metals. That’s because during the planet’s formation about 4.5 billion years ago, some of the ruthenium that is locked inside Earth’s core originated from a different source than the small amount found in the mantle today. The discrepancies between these two forms of ruthenium is so slight that the equipment used by geologists to study these isotopes hasn’t been able to tell the two apart.

Excerpt:A new study has shown that community trust in Australian and New Zealand scientists is the highest in the developed world, and the authors say – surprisingly – it might be because local politics doesn’t get in the way.
Not everyone agrees.
The survey results were posted yesterday. The study of 70,000 respondents compares public trust in climate scientists and scientists in general across 68 countries.
It reveals that on average, participants reported moderately high levels of trust in climate scientists, with trust levels being slightly lower than in scientists in general.
“Overall, this trust gap was larger among participants who identified as politically conservative or right-leaning, but there was considerable variation across countries,” the report concludes.

A U.S. federal judge on Wednesday rejected arguments made by an artificial intelligence company that its chatbots are protected by the First Amendment — at least for now.
The developers behind Character.AI are seeking to dismiss a lawsuit alleging the company’s chatbots pushed a teenage boy to kill himself. The judge’s order will allow the wrongful death lawsuit to proceed, in what legal experts say is among the latest constitutional tests of artificial intelligence.
The suit was filed by a mother from Florida, Megan Garcia, who alleges that her 14-year-old son Sewell Setzer III fell victim to a Character.AI chatbot that pulled him into what she described as an emotionally and sexually abusive relationship that led to his suicide.
Meetali Jain of the Tech Justice Law Project, one of the attorneys for Garcia, said the judge’s order sends a message that Silicon Valley “needs to stop and think and impose guardrails before it launches products to market.”

We’ve all felt the sting of guilt when fruit and vegetables go bad before we could eat them. Now, researchers from MIT and the Singapore-MIT Alliance for Research and Technology (SMART) have shown they can extend the shelf life of harvested plants by injecting them with melatonin using biodegradable microneedles.
That’s a big deal because the problem of food waste goes way beyond our salads. More than 30 percent of the world’s food is lost after it’s harvested — enough to feed more than 1 billion people. Refrigeration is the most common way to preserve foods, but it requires energy and infrastructure that many regions of the world can’t afford or lack access to.
The researchers believe their system could offer an alternative or complement to refrigeration. Central to their approach are patches of silk microneedles. The microneedles can get through the tough, waxy skin of plants without causing a stress response, and deliver precise amounts of melatonin into plants’ inner tissues.

A new study suggests that AI could speed up the grading process for teachers, but it may sacrifice some accuracy in the process.
Many states have adopted the Next Generation Science Standards, which emphasize the importance of argumentation, investigation, and data analysis. But teachers following the curriculum face challenges when it’s time to grade students’ work.
“Asking kids to draw a model, to write an explanation, to argue with each other are very complex tasks,” says Xiaoming Zhai, corresponding author of the study and an associate professor and director of AI4STEM Education Center in University of Georgia’s Mary Frances Early College of Education.
“Teachers often don’t have enough time to score all the students’ responses, which means students will not be able to receive timely feedback.”
The study explored how Large Language Models grade students’ work compared to humans. LLMs are a type of AI that are trained using a large amount of information, usually from the internet. They use that data to “understand” and generate human language.
