This Akhal-Teke horse looks like it's made of gold... and yes, it sold for $15 million.
The Akhal-Teke is a rare Turkmen horse breed, famous for its distinctive, shiny, metallic coat, often described as "golden," earning it the nickname "Golden Horse." Originally from Turkmenistan, it is considered one of the oldest and purest breeds, renowned for its exceptional speed, endurance, and intelligence.

Sweden is committing more than €100 million to a sweeping classroom overhaul: replacing tablets and screens with traditional printed textbooks to help reverse falling student performance and sharpen focus.
After more than a decade of embracing digital-first education, Swedish authorities are now pivoting back to paper-based learning. Official data and recent studies cited by the Ministry of Education show that prolonged screen use in class has been linked to shorter attention spans, weaker reading comprehension, and reduced critical-thinking abilities.
Research consistently finds that reading on illuminated screens requires greater mental effort and invites more distractions compared to the calm, linear experience of physical books—factors believed to have contributed to declining academic outcomes in recent years.
Under the new plan, every student will receive printed textbooks for all core subjects, restoring books as the central learning tool. Digital devices and online resources will remain available as supportive tools, but they will no longer dominate daily instruction.
This bold €100+ million investment signals Sweden’s leadership in rethinking the role of technology in education. It underscores a broader, growing recognition worldwide: while screens provide speed and access, the hands-on, distraction-free engagement of physical books supports deeper concentration, stronger memory retention, and more effective long-term learning.
By choosing paper over pixels, Sweden is charting a path toward a more balanced, evidence-informed classroom future—one that puts proven pedagogical principles ahead of unchecked digital trends.

A 15-pound honey badger can survive a cobra bite that would kill a full-grown man in under two hours. Then it finishes eating the snake. A biology grad student at the University of Minnesota wanted to know how. She needed badger blood to find out, and the only samples she could get were from two American zoos in San Diego and Indiana.
What she found in the DNA was one tiny change. There's a small socket on your muscle cells that your nerves plug into to tell your muscles to move. Cobra venom kills you by jamming that socket shut, so your lungs stop working. The honey badger's socket has a swapped-out amino acid that gives it a positive electrical charge. Cobra venom is also positively charged. Like magnets pointing the wrong way, the venom gets pushed off before it can lock in, and the muscles keep firing.
The same workaround showed up separately in hedgehogs and pigs. Mongooses got there too, with a slightly different molecular trick. Four different animals with no shared ancestor all arrived at the same solution because venomous snakes kept biting them for millions of years.
That only covers snakes like cobras and mambas. Puff adders work differently, destroying tissue instead of paralyzing muscle, and the DNA trick doesn't help there. So when a puff adder lands a solid bite, the badger collapses into a kind of coma for two or three hours. Then it wakes up groggy and eats the snake anyway.
The skin is maybe the unfairest part of all this. It's about a quarter inch thick, rubbery, and so loose it fits like a wetsuit two sizes too big. A lion can clamp its jaws on a honey badger and the badger will twist halfway around inside its own skin and start clawing the lion's face while still in its mouth. Bee stingers barely get through. Porcupine quills don't either.
Which brings us back to the bees in that photo. They're annoying. A few sneak through to the face, and enough stings have killed honey badgers in the wild. Honey badgers still die. But they're running three different defense systems at the same time, and one of them is a genetic lottery ticket evolution has pulled four times.

The dentate gyrus is the main region of your adult brain that keeps generating new neurons. Two hours of silence a day produces more of them than Mozart, pup calls, or white noise.
Your hippocampus encodes memory. Inside it sits the dentate gyrus, where adult neurogenesis actually happens. New cells sprout there throughout your life, migrate a few millimeters, and wire themselves into existing memory circuits.
In 2013, Imke Kirste's lab at Duke ran four mouse groups through two-hour daily auditory stimuli: Mozart's KV 448, pup distress calls, white noise, and silence as the control. Silence was meant to do nothing. It beat every sound condition. BrdU staining showed a significant jump in Sox2-positive precursor cells in the dentate gyrus, and follow-up imaging showed those cells differentiating into functional neurons that integrated into the circuit.
The second mechanism shows up in cardiovascular data. Luciano Bernardi's 2006 study in Heart randomized 2-minute silent pauses between music tracks across 24 subjects. The silent gaps dropped heart rate, blood pressure, and minute ventilation below baseline, more than any "relaxing" music produced. Vagus nerve activity rises, parasympathetic tone takes over, cortisol drops. The nervous system treats silence as an active recovery signal.
The third is the Default Mode Network. When your auditory cortex stops parsing incoming sound, the DMN lights up across the medial prefrontal cortex, posterior cingulate, and angular gyrus. Marcus Raichle's work showed this network consumes nearly as much energy at rest as your brain does when task-focused. Memory consolidation, future planning, and associative thinking all happen inside it. Silence gives it floor space.
Three systems at once. Neurogenesis in the one part of adult brain that still grows. Parasympathetic recovery through the vagus nerve. Default Mode activation for memory consolidation and insight.

UNUSUAL🚨: Scientists discover that silence regenerates the brain─ being in complete silence for at least 2 hours a day can stimulate the creation of new brain cells, especially in regions linked to memory and learning.
