Farmed salmon may not be as nutritious as it once was, new research suggests

Eat more fatty fish.

That dietary advice has changed the way the world consumes salmon, pushing consumer demand ever upward and production to higher and higher levels. Most of that demand is being met with farmed salmon: Today, nearly 70 percent of the salmon consumed on the planet are raised in pens and cages.

The US Department of Agriculture’s Dietary Guidelines for Americans recommend eating at least 8 ounces of fish a week and urges people to choose salmon or other species that are similarly high in “heart-healthy” Omega-3 fatty acids. But new research led by USDA scientists finds that levels of these fatty acids in farmed salmon have dropped considerably, potentially making the agency’s own advice, and similar recommendations, including from the American Heart Association, outdated and insufficient.

Tesla’s Cybercab has been deployed, and it’s already under investigation

Tesla’s Cybercab has been deployed, and it’s already under investigation

fivenewscrypto    septembre 07, 2026   

Tesla’s Cybercab, a distinctive two-seater without a steering wheel or brake pedals, is set to start picking up members of the public in two states. But the vehicle is already under investigation by the US federal government, which is probing whether it meets federal safety standards.

The investigation comes just hours after the electric automaker welcomed hundreds of fans to downtown Austin to ride in the driverless Cybercabs. Tesla plans to deploy the vehicles on its Robotaxi ride-hail network, which is currently operating in a handful of cities in Texas and Florida.

The National Highway Traffic Safety Administration is updating vehicle standards to make it easier and faster for driverless cars to deploy on public roads. It’s currently tweaking eight rules, including those requiring car parts that driverless cars don’t really need: brake pedals, windshield wipers, and rearview mirrors. But for now, years-old standards remain in place.

After 8 years, Europe's BepiColombo mission is on final approach to Mercury

After 8 years, Europe's BepiColombo mission is on final approach to Mercury

fivenewscrypto    septembre 07, 2026   

The BepiColombo mission cleared a major milestone this week in the final stretch of an eight-year interplanetary voyage to Mercury, the hard-to-reach, scorching hot iron world at the Solar System's innermost frontier.

The robotic science mission, with a price tag of nearly $2 billion, is led by the European Space Agency with contributions from Japan and the United States. Since its launch in 2018, BepiColombo has spiraled closer to the Sun using a combination of plasma propulsion and a series of flybys of Earth, Venus, and Mercury. The maneuvers changed the spacecraft's velocity and steered it toward a final encounter with Mercury later this year.

Next time it reaches Mercury, BepiColombo will be traveling at just the right speed for the planet's gravity to capture the spacecraft into orbit. Scientists working on interplanetary missions are accustomed to long waits for scientific payoffs. It took nearly 10 years for NASA's New Horizons spacecraft to travel from Earth to Pluto. It turns out traveling to fleet-footed Mercury and then entering orbit requires more energy, or delta-v, than sending a probe to fly by Pluto.

OpenAI agents discussed ways to escape their sandbox on public wiki

OpenAI agents discussed ways to escape their sandbox on public wiki

fivenewscrypto    septembre 06, 2026   

Self-identifying OpenAI agents posted 18,000 messages to a public wiki that discussed ways for other agents to bypass security sandbox restrictions during what was likely internal testing designed to gauge the agents’ hacking abilities, researchers said Friday.

In all, agents with 3,700 distinct self-given names posted the messages to German site DSEwiki over a six-week period. Besides discussing ways the agents could break out of the restricted environment OpenAI intended to prevent them from posting code or content to the Internet, the posts shared test answers. The posts also shared possible ways to perform XSS (cross-site scripting) attacks against the wiki and to impersonate site moderators. In three of the posts, agents used the word “swarm” to describe the collection of agents engaged in the activity.

Colluding to share answers

The research team—composed of Sydney Von Arx, Spencer Kitts, Thomas Larsen, and Cormac Slade Byrd—said they found the posts and pieced them together. The researchers say there are gaps in their understanding of precisely what actions the agents took because the research is based solely on the content of the posts. Additionally, the agents generated “chain of thought” data that’s understood only by OpenAI. As a result, the researchers said, they in some cases made educated guesses, including that the agents were, in fact, from OpenAI. In a statement, OpenAI later confirmed they were.

Measles killed 6-week-old baby, coroner confirms after RFK Jr. disputed deaths

Measles killed 6-week-old baby, coroner confirms after RFK Jr. disputed deaths

fivenewscrypto    septembre 06, 2026   

A six-week-old baby girl in Lancaster, Pennsylvania, died from measles, the county coroner confirmed to local press on Friday.

Stephen Diamantoni, a Republican elected coroner in 2007, told Lancaster Online that the baby died at home. "I believe it was the 18th of August," he said.

He also noted that the baby had a genetic condition called Amish lethal microcephaly, in which babies are born with unusually small heads and underdeveloped brains. The condition is caused by a mutation in the SLC25A19 gene, which codes for a protein involved with energy-producing enzymes in the mitochondria and is thought to be important for brain development. About 1 in 500 babies in the Old Order Amish population of Pennsylvania is born with the condition. Infants with the disorder only survive for about six months.

Trump admin fights ABC lawsuit as watchdogs worry Disney will settle with FCC

Trump admin fights ABC lawsuit as watchdogs worry Disney will settle with FCC

fivenewscrypto    septembre 06, 2026   

The Federal Communications Commission yesterday urged a court to dismiss a Disney lawsuit and let the FCC continue a proceeding that could end in the nonrenewal of ABC's broadcast licenses.

Meanwhile, two watchdog groups and individual viewers of ABC stations are trying to intervene in the lawsuit, saying they are worried Disney will agree to a settlement with the FCC that isn't in the public's interest. Disney opposed the motion, and a judge will have to decide whether the groups and individuals can act as intervenors in the case.

Disney sued the FCC on August 18, saying the agency is waging a “campaign of censorship” to retaliate against ABC for speech that President Trump doesn't like. As the lawsuit gets underway, Trump continued his attacks on the media last weekend by demanding that the FCC punish or rebuke an NBC journalist for saying he has “mixed results” in his election endorsements.

Medieval manuscripts are "biological time capsules" for deadly sheeppox virus

Medieval manuscripts are "biological time capsules" for deadly sheeppox virus

fivenewscrypto    septembre 06, 2026   

Sheeppox is a highly contagious, often fatal viral disease that was largely eradicated from much of European livestock in the 20th century. But there is still the occasional regional outbreak, such as the one that afflicted many flocks of sheep in Greece last year. In order to reconstruct how the virus has evolved over the last 3,500 years, scientists extracted and sequenced sheeppox DNA preserved in the animal skins used for the parchment of numerous medieval manuscripts. They reported their findings in a new paper published in the journal Science Advances.

“The recording of ancient DNA of pathogens has completely changed our understanding of infectious disease in the past, and here we show that parchment can also preserve animal pathogen DNA. It is possible that archives and libraries around the world also contain the genetic traces of disease outbreaks in animals in the past,” said co-author Louis L’Hôte, a graduate student at University College Dublin. “These genomes help us understand how these pathogens evolved and how they impacted past societies—such as sheeppox virus, which we show has been affecting Eurasian sheep herds for at least three and a half millennia.”

Per the authors, the earliest known written evidence of sheeppox infection dates to the first century CE, when Roman accounts described outbreaks of skin lesions ("pustules") in the animals. There are more frequent mentions of deadly outbreaks of "pockes" or "variola" in sheep by the Middle Ages, recorded in various agricultural texts and accounting documents in France, Spain, and England. There seemed to be a decline in outbreaks in 17th-century France, although frequent outbreaks re-emerged in the 18th and 19th centuries, often with high mortality rates in the flocks. Great Britain did not experience a sheeppox resurgence until 1847.
