Doctors warn of a stealth opioid 20x more potent than fentanyl

Nitazenes, a powerful and largely hidden class of synthetic opioids, are quickly becoming a deadly factor in the overdose crisis. Over 20 times stronger than fentanyl, these drugs often go undetected on routine drug tests, making overdoses harder to diagnose and reverse. Cases from Tennessee reveal a disturbing pattern of fatalities, with nitazenes frequently mixed into counterfeit pills alongside fentanyl and methamphetamine. Source link

How parakeets make new friends in a surprisingly human way

Monk parakeets ease into new friendships, slowly approaching strangers to avoid aggressive encounters. Researchers watched how birds shared space, groomed each other, and escalated to deeper social bonds over time. The results show a clear pattern of cautious exploration echoing similar studies in other animals. Even for birds, making a friend can be a delicate dance. Source link

A mysterious metal find in Sweden is rewriting Iron Age history

A Swedish plano-convex ingot once thought to be from the Bronze Age was revealed through chemical and isotopic testing to belong to the Iron Age. Its composition closely matches Iron Age finds from Poland, leading researchers to uncover new evidence of long-distance connections across the Baltic. The study highlights how collaboration and scientific analysis can transform isolated artifacts into clues about ancient trade and networking. Source link

Shocking study exposes widespread math research fraud

A sweeping investigation has revealed widespread fraud in mathematics publishing, where commercial metrics and rankings have incentivized the mass production of meaningless or flawed papers. The study highlights shocking distortions—such as a university without a math department ranked as having the most top mathematicians—and the explosion of megajournals willing to publish anything for a fee.

This surprising building material is strong, cheap, and sustainable

A team at RMIT University has created a cement-free construction material using only cardboard, soil, and water. Strong enough for low-rise buildings, it reduces emissions, costs, and waste compared to concrete. The lightweight, on-site process makes it ideal for remote areas, while its thermal properties naturally cool buildings. Researchers see it as a key step toward greener, more resilient architecture.

This vibrant moth fooled scientists for generations

For more than a century, a dazzling pink-and-yellow moth was mistaken for a common European species, but DNA analysis revealed it as entirely new: Carcina ingridmariae. Found across the eastern Mediterranean, this hidden beauty had evaded recognition until advanced barcoding techniques exposed its genetic secrets. Entomologist Dr. Peter Huemer confirmed the discovery and, in a heartfelt gesture, named the moth after his wife on their 42nd anniversary, celebrating both science and love. Source link

Tylenol in pregnancy linked to higher autism risk, Harvard scientists report

Researchers reviewing 46 studies found evidence linking prenatal acetaminophen (Tylenol) exposure with higher risks of autism and ADHD. The FDA has since urged caution, echoing scientists’ advice that the drug be used only at the lowest effective dose and shortest duration. While important for managing fever and pain in pregnancy, prolonged use may pose risks to fetal development. Experts stress careful medical oversight and further investigation. Source link

This forgotten king united England long before 1066

Æthelstan, crowned in 925, was the first true king of England but remains overshadowed by Alfred the Great and later rulers. A new biography highlights his military triumphs, legal innovations, and cultural patronage that shaped England’s identity. From the decisive Battle of Brunanburh to his reforms in governance and learning, Æthelstan’s legacy is finally being revived after centuries of neglect. Source link

A tiny enzyme may hold the key to safer pain relief

Researchers have uncovered a surprising way the brain switches pain on, revealing that neurons can release an enzyme outside the cell that activates pain signals without disrupting normal movement or sensation. This enzyme, called VLK, modifies nearby proteins in a way that intensifies pain and strengthens connections tied to learning and memory. Removing VLK in mice dramatically reduced post-surgery pain while leaving normal function untouched, offering a promising path toward safer, more targeted pain treatments. Source link

Scientists may have found the planet that made the Moon

About 4.5 billion years ago, a colossal impact between the young Earth and a mysterious planetary body called Theia changed everything—reshaping Earth, forming the Moon, and scattering clues across space rocks. By examining subtle isotopic fingerprints in Earth and Moon samples, scientists have reconstructed Theia’s possible composition and birthplace. Source link

Four strange secrets scientists just found in beer and wine

Beer and wine, staples of human history for millennia, are still yielding new surprises. Recent research highlights how yeast extracts can cloud lagers, gluten can be quickly detected with a simple test strip, tannins give red wine its lip-puckering edge, and sulfites alter gut bacteria in unexpected ways. These discoveries not only deepen our understanding of these drinks’ sensory qualities but also hint at implications for health and brewing innovation. Source link

Why Gen X women can’t stop eating ultra-processed foods

Researchers found that middle-aged adults, especially women, are far more likely to be addicted to ultra-processed foods than older generations. Marketing of diet-focused processed foods in the 1980s may have played a major role. Food addiction was linked to poor health, weight issues, and social isolation, highlighting long-term risks. Experts warn that children today could face even higher addiction rates in the future. Source link

Viral apple cider vinegar weight loss study retracted for flawed science

BMJ Group has pulled a widely reported apple cider vinegar weight-loss study after experts uncovered major flaws in its data and analysis. Attempts to replicate the results failed, and irregularities raised questions about the trial’s reliability. The authors admitted mistakes and agreed to the retraction, while editors stressed the importance of transparency and warned against citing the discredited findings. Source link

Black hole blast outshines 10 trillion Suns

A colossal black hole 10 billion light-years away has been caught devouring one of the universe’s biggest stars, unleashing a flare 30 times brighter than any seen before. The flare, detected by Caltech’s ZTF, likely marks a tidal disruption event — when a star is shredded by a black hole’s gravity. Source link

How gaslighting tricks the brain into questioning reality

Gaslighting, often seen as a form of manipulation, has now been reframed by researchers at McGill University and the University of Toronto as a learning process rooted in how our brains handle prediction and surprise. Instead of merely being explained through outdated psychodynamic theories, this new model highlights how trust and close relationships can be exploited by manipulators who repeatedly undermine a person’s confidence in their own reality.
