By the time doctors detect pancreatic cancer, it’s often too late to treat effectively. But a new study suggests that artificial intelligence might be able to find signs of the disease before tumors are visible on a scan. An AI model developed at the Mayo Clinic in Rochester, Minnesota, detected abnormalities on patients’ CT scans up to three years before they were diagnosed with pancreatic cancer, according to research published this week in the journal Gut. The scientists behind the model, which is now being evaluated in a clinical trial, trained it by feeding it CT scans from patients who...

A team of astronomers in Japan has detected a thin atmosphere around (612533) 2002 XV93, a trans-Neptunian object about 500 km in diameter — an object far too small and cold to retain one. An artist’s conception of the trans-Neptunian object 2002 XV93. Image credit: NAOJ. “In the cold reaches of the outer Solar System lie thousands of small objects known as trans-Neptunian objects (TNOs) because they lie outside the orbit of Neptune,” said Dr. Ko Arimatsu from Ishigakijima Astronomical Observatory and colleagues. “A thin atmosphere has been observed around Pluto, the most famous TNO, but studies of other TNOs...

Explanation: Orion is rarely seen like this. To achieve this majestic vista, you need a camera capable of taking such long duration exposures that faint features in the night sky become revealed. Iconic nebulas that appear include the Orion Nebula, the Flame Nebula, and Barnard's Loop. For contrast, it also helps to have a volcano on the foreground, in this case the Teide volcano on Tenerife on the Canary Islands of Spain. But if you want your Teide volcano snow-covered, you also need good timing -- because that only happens, typically, for a few days each year. Good timing also...

Minocqua Brewing Company owner Kirk Bangstad, who offered free beer in the event of President Donald Trump's death, announced his bid for Wisconsin governor on Sunday. "I’m running for Governor because I believe Wisconsin needs a battle-hardened fighter to join the rest of America to save our Democracy from Trump’s regime, and that person doesn’t exist in the crowded field of Democrats currently running in Wisconsin’s Gubernatorial primary," Bangstad wrote in a Substack post on Sunday. Bangstad's announcement came a little over a week after his brewery advertised free beer in the event of Trump's death. The Facebook comments came...

Overshadowed by the rise of the Roman Empire, the Etruscan civilization -- and their exquisite art, progressive society, and advanced engineering -- was largely forgotten by history. This film reclaims their story, revealing how Etruscan innovations and customs were the foundation upon which the entire Roman world was built, and how their legacy continues today.

In the ancient Egyptian city of Oxyrhynchus, archaeologists recently discovered a 1,600-year-old tomb with several mummies inside. Some of them were decorated with gold leaf or geometric patterns—features commonly found in burials of this kind.But one of the mummies was unearthed alongside a particularly unusual artifact: a papyrus fragment from Homer's Iliad, the epic poem set during the Trojan War. The ancient Greek text had been tucked beneath the wrappings on the mummy's abdomen during the embalming process."The fact that in this case the text, in Greek, refers to a literary text is truly novel," say Maite Mascort and Esther...

According to a statement released by the University of South Florida, a mass grave containing the remains of victims of the Plague of Justinian (A.D. 541–750) has been identified at the site of Jerash in northern Jordan by a team of researchers led by Rays H.Y. Jiang of the University of South Florida. Hundreds of people were buried within several days in this mass grave dug in the city's hippodrome. "By linking biological evidence from the bodies to the archaeological setting, we can see how disease affected real people within their social and environmental context," Jiang said. Examination of the...

BRAKER hitting its target - US Army One of the biggest hitters in the conventional arsenal merged with drone technology, as the US Army tested a bunker-buster warhead combined with an expendable Unmanned Aerial Vehicle (UAV) for field testing at Redstone Arsenal in Alabama. Bunker busters are a classic example of using brute force to overcome a seemingly impossible obstacle. There is something audacious about responding to the challenge of an impregnable fortress with what amounts to the arms equivalent of “hold my beer.” The idea is to deal with a heavily armored or deeply buried target by dropping a...

According to a statement released by the Max Planck Institute of Geoanthropology, an international team of researchers compared models for the distribution of three major mosquito complexes, paleoclimate models, and places where early humans lived in sub-Saharan Africa between 5,000 and 74,000 years ago. The resulting map indicates that people avoided or died out in areas where Plasmodium falciparum-induced malaria, a disease transmitted by mosquitoes, was likely prevalent. "The effects of these choices shaped human demography for the last 74,000 years, and likely much earlier," said Andrea Manica of the University of Cambridge. "By fragmenting human societies across the landscape,...

According to a statement released by Antiquity, analysis of skeletal remains recovered from a seventeenth-century hospital cemetery in Basel, Switzerland, suggests that young laborers were the people most likely to die during an outbreak of plague. As a trade center that drew people in from abroad, the city of Basel was vulnerable to the spread of Yersinia pestis bacteria and outbreaks of plague. The last recorded outbreak of the disease in Basel occurred between 1665 and 1670. Researchers led by osteoarchaeologist Laura Rindlisbacher of the University of Basel examined skeletal remains recovered from the hospital cemetery dated to this period,...

According to a statement released by the University of Copenhagen, analysis of the remains of 132 individuals unearthed near a megalithic tomb in northern France suggests that the site was initially used by one group of people, but that population declined around 3000 B.C. and was eventually replaced by another group. "We see a clear genetic break between the two periods," said Frederik Valeur Seersholm of the University of Copenhagen. Genetic testing revealed that the earlier group was composed of early farmers from northern France and Germany, while the later group was linked to people in southern France and the...

American attack helicopters sank six Iranian small boats in the Strait of Hormuz on Monday — as the Trump administration works to back the regime into a corner — forcing it to choose between allowing ships through the strait or attacking them and provoking a return to war. Two US-flagged cargo ships successfully passed through the strait as part of a new American initiative, “Project Freedom.” Frustrated by the lack of progress with Iranian negotiators, Trump is allegedly forcing Iran’s hand by deploying US warships directly into the Strait of Hormuz to escort neutral vessels that have been trapped in...

Live Science reports that Joachim Burger of Johannes Gutenberg University Mainz and his colleagues examined more than 250 sets of human remains of people who lived in what is now southern Germany, on what was the frontier of the Roman Empire, between A.D. 400 and 700. The researchers analyzed DNA samples from the bones, performed strontium isotope analysis to look for chemical signatures in the bones, and compared the results of the tests with 2,500 ancient and 379 modern genomes. The study suggests that many people engaged in monogamy, and nearly one-quarter of the children lost at least one parent...

'He was hiding in plain sight.' ANebraska middle school teacher is accused of utilizing artificial intelligence to create more than a hundred child sexual abuse images — and the teacher allegedly masturbated to the disturbing child pornography while at a school, according to multiple reports. The Nebraska State Patrol said in a statement that 47-year-old Matthew Lund was arrested at his Omaha home at approximately 6:15 a.m. April 22. Lund was booked into Douglas County Corrections and charged with possession of child sexual abuse material and distribution of child sexual abuse material. A judge set Lund's bond at $1 million...

Explanation: Why are there huge, unusual masses inside the Earth? No one is sure. By noting how earthquakes rumble through our planet's interior, humanity has discovered two deep structures that appear to have unusual temperatures and/or chemical compositions. One hypothesis holds that the superplumes are sunken debris left over from the Earth-shattering collision that created Earth's Moon about 4.5 billion years ago. A competing hypothesis is that they are graveyards for old tectonic plates that slowly slid under each other over the past few billion years. No matter their origin, the superplumes are thought to affect Earth’s surface volcanism, possibly...

Here is the unvarnished truth that has been kept secret by the choices of important people. At present population levels, there may be more than enough energy in the world for the next 100,000 years (maybe for millions of years) that is relatively easy to obtain, clean, and safe, and that would be productive of peace among men, because there would be fewer fights over resources. The fuel of the future is thorium, and it is being withheld from the world because too few people know about it to demand it—and there’s no reason for this ignorance. Why the secrecy?...

Interesting concept of solar panel system plugged directly into a household outlet for a do it yourself supplemental power supply. According to the video (and other sources) it's newly legal in Utah and several other states. It's also in wide spread use in Europe. I know there are several Freepers who have solar power of different types, I've always been interested in the subject but have never gone past solar battery charging for boats or cars or cameras.

I still remember fondly the time I got an A- on my 8th grade earth science paper. It was one of my proudest moments as a student. Meanwhile, as MIT boasts, some folks are, well, a bit beyond that. Physics is riddled with paradoxes: Think of how information leaks from supposedly inescapable black holes or how the conventional laws of physics break down at the quantum scale. Sabrina Gonzalez Pasterski '13 believes that within these apparent contradictions, new discoveries await. Ah yes, "how the conventional laws of physics break down at the quantum scale." I think about that often! Well,...

Explanation: Dust pillars are like interstellar mountains. They survive because they are more dense than their surroundings, but they are slowly being eroded away by a hostile environment. Visible in the featured picture by the Hubble Space Telescope is the end of a huge gas and dust pillar in the Trifid Nebula (M20), punctuated by a smaller pillar pointing up and an unusual jet pointing to the upper left. Many of the bright dots are newly formed stars. A star near the small pillar's end is slowly being stripped of its accreting gas by radiation from a tremendously brighter star...

If everything goes to plan, Alex Bellini could become the first person to live on an iceberg, where temperatures hover between 5 to −4 degrees Fahrenheit and gale-force winds blow. The 38-year-old Italian public speaker and adventurer, who crossed two oceans alone on a row boat and ran across the U.S. in 70 days, recently spoke about his project, Adrift, a years’-long ambition to live in a survival capsule on a Greenland iceberg. Once a suitable iceberg is selected, Bellini plans to conduct research on climate change‘s affect on ice sheets and to test the limits of human endurance and...
