Cryptococcus gattii, a tropical fungus that only grows on rotting wood, was introduced to Pacific Northwest waters via ship ballast from Brazil around 1900. The 1964 Alaska tsunami spread it inland, where it adapted for decades — by the 1990s it was causing mysterious fatal outbreaks that baffled epidemiologists.

One of the earthquake's most puzzling aspects was the speed of local tsunamis. Standard tsunami models couldn't account for waves arriving at coastal towns within just 4 minutes of the quake — the physics simply didn't work [1] — Chuck "Scientists couldn't explain why some coastal Alaskan towns were hit by tsunamis within just 4 minutes of the earthquake. The answer: Alaska…" 23:50 . The explanation, when scientists finally found it, was hidden in Alaska's unique geography. The state's deeply carved fjords — ancient glacial channels — had over centuries deposited enormous quantities of silt onto the seafloor at their mouths. When the earthquake hit, it stirred all of that silt and sediment like sand in a shaken glass, triggering massive underwater landslides. These landslides, in turn, generated their own local tsunamis — arriving far faster than any wave from a distant epicentre could. A new scientific term was coined: the landslide tsunami. It's a phenomenon that now shapes how coastal communities everywhere think about post-earthquake safety, and it was identified here first.
Scientists couldn't explain why some coastal Alaskan towns were hit by tsunamis within just 4 minutes of the earthquake. The answer: Alaska's jagged fjord coastline had deposited centuries of silt on the ocean floor, and the quake triggered massive underwater landslides — a phenomenon now called a landslide tsunami.
Social norms compress behavior so effectively that we assume other minds are similar to ours. They almost never are. After running over 100 psychology studies, Greenberg's biggest finding is that humans are far more different from each other than we intuitively believe.
The widely shared claim that we have a credit card's worth of plastic in our brains may be a massive overestimate. Researchers used nitrile gloves to measure microplastics — and nitrile gloves shed microplastic particles onto the measuring device. A second paper found the original tool used was unreliable, and that we may have far less plastic than reported.
RSD isn't just hurt feelings — it's a dopamine-deficient brain with a hyperactive amygdala and a frayed connection to the prefrontal cortex. Add a surge of norepinephrine and you get chest pain, sweating, and trembling that convinces your body something catastrophic is happening.
In Dan Ariely's door experiment, participants sacrificed the highest-reward door — repeatedly — just to avoid seeing other doors disappear. Even when researchers trained them to use the best door, they kept wasting clicks to maintain options. This is the bias that runs our lives: we'll take a worse outcome to preserve the feeling of optionality.
Dan Gilbert discovered that the brain has a 'psychological immune system' — it misremembers, reframes, and rationalizes to keep you satisfied with whatever you chose. The fear before commitment is all about potential regret. But after committing, your brain quietly starts justifying the choice — and the more irreversible the decision, the stronger the effect.
The psychological immune system can get you through the first few months of any commitment. But durable, long-term well-being requires self-concordance — choosing commitments that are genuinely aligned with your values and what you actually want. Without that alignment, the satisfaction fades fast.
Vision didn't just help animals find food — it ignited the Cambrian explosion of speciation. Half of the human cortex is devoted to visual processing, and that same visual hierarchy directly inspired the neural network architectures powering today's AI.
Peptides come loaded with a powerful narrative: regenerative, subcutaneous, targeted, cutting-edge. That narrative can genuinely move outcomes, especially for pain, energy, and recovery. The RCT's job is to quantify how much additional benefit comes from the molecule itself — above and beyond the compelling story surrounding it.
A pharmaceutical is not an amino acid sequence — it is the successful solution to manufacturing, purification, formulation, and consistency challenges. When clinical trials prove a drug works, they validate a specific product under specific processes, not every preparation that shares the same sequence.
