per il pancreas si attesta intorno a circa l'11-12%

Vaccino a mRNA contro il cancro al pancreas.
Quasi tutti i pazienti che hanno risposto al vaccino sono ancora vivi a sei anni di distanza.
Lasciamo pure che giornalisti e politici sbraitino nelle piazze o nelle aule del Senato: la scienza va avanti.

Caro @MauroMazzaRai usi il singolare e non il plurale, abbia il coraggio delle sue azioni e non ci coinvolga. Io non sono come lei e mi stupisco che un uomo, un giornalista che ha fatto parte del servizio pubblico abbia un pensiero così gretto.

Flavio Cobolli SCONFITTO in finale a Monaco di Baviera: a trionfare è lo statunitense Shelton, che vince il suo 5° titolo ATP, il 2° su terra e il 3° in un '500', che diventa il 1° statunitense a vincere un titolo su terra che non sia di categoria '250' da Agassi (Roma 2002) 🏆
Ottima settimana comunque per Flavio, che da domani sarà 13° al mondo, eguagliando il suo career high.

Hans Niemann reveals how much top chess players actually make
“Top 3 player in the world you’re making around $1,000,000 a year depending on your endorsements”
“A top 5 player is making $600,000 to $800,000 and a top 10 player depending on sponsors is making around $300,000”
“Top 20 player in the world you’re lucky to make $100,000 to $150,000… top 40 player in the world and you’re lucky to make $100,000 a year. So there’s a huge, huge drop-off”
“I think last year I won maybe $350,000 in prize money… but if I wasn’t blacklisted I’d be making much, much more”
“I’ve had countries offer me ridiculous amounts of money to represent them”

For those without context, the supposed #1 player would be considered inactive in any other sport and wouldn’t be able to maintain his ranking. Tennis is the perfect example. Rating/rankings should reward ACTIVITY!

Orcas eat great white sharks. They hunt seals, dolphins, and baby whales. They have never killed a single human in the open ocean. Not once, in all of recorded history.
An orca's brain weighs up to 15 pounds. Yours weighs about 3. They have roughly double the brain cells we do in the regions that handle complex thought. A neuroscientist at Emory named Lori Marino put an orca brain in an MRI and found these animals can tell different species apart underwater. They do it by sending out clicks that bounce off everything around them and come back as a kind of 3D sound map (this is called echolocation). From 500 feet away, an orca knows you're a human and not a seal. It skips you on purpose.
The answer is culture. Orcas around the world are divided into at least 10 separate populations, each with its own food rules, its own language, and its own way of hunting. All of it learned from their mothers. One population eats only fish. Another eats only marine mammals like seals and sea lions. These two populations can live in the exact same water and never swap a single meal. A baby orca learns what food is from its mother, and that list stays the same for life.
In the Pacific Northwest, one population called the Southern Residents eats almost nothing but Chinook salmon. Scientists have documented them killing harbor porpoises 78 times over six decades, carrying the dead porpoises in their mouths, and never once eating them. Even when the group was starving. A 2023 study in Marine Mammal Science looked at all 78 cases and concluded it was play. These orcas would rather go hungry than eat something their culture says isn't food.
Researchers studying whale behavior in 2001 found that orca cultural traditions "appear to have no parallel outside humans." Each family group has its own dialect, its own version of the language. Calves spend about two years just learning how to make all the sounds their family uses. Mothers will slow down a hunt on purpose so their young can watch.
In 2005, a 12-year-old kid was swimming in Helm Bay, Alaska when an orca came at him full speed. At the very last second, the orca seemed to realize it was charging a human. It bent its entire body in half and turned back to open water. In captivity, it goes differently. SeaWorld's Tilikum killed three people during his life in a concrete tank. Research from 2016, published in the journal Animals, traced it to psychological collapse from being locked away from the family bonds orcas need to stay stable.
I think calling this a "mystery" undersells the science. Orcas decide what to eat based on culture, not instinct. No orca mother has ever taught her calf to hunt humans, so no orca hunts humans. Only about 75 of those salmon-eating Southern Residents are still alive. Their pregnancy failure rate is 69% because we've destroyed their salmon runs. They won't break their food culture to survive. Whether we care enough to protect theirs is the part that actually matters.

One of the biggest mysteries to me is how Orcas, the ocean’s most efficient predators, have never attacked humans in the wild… almost like they know something we don’t.
