Reply to Men with prostate cancer who also had relatives affected by the disease – or by other cancers with an inherited element like breast, ovarian or bowel cancer – were up to a fifth less likely to die from prostate cancer or any cause compared with those with no family history of cancer by giuliomagnifico

"were up to a fifth less likely to die from prostate cancer or any cause compared with those with no family history of cancer".. Misleading because "or any cause" means death for whatever reason you can think of..

Reply to comment by Feudamonia in The brain can rapidly detect and process fearful faces that are otherwise invisible to the eye. There appears to be a neural pathway for detection of fear, which operates automatically, outside of conscious awareness. by Wagamaga

Just because the alternative meaning is illogical in your mind doesn’t mean the description is accurate. Accuracy is important, why wouldn’t you want to be as precise as possible? Especially when discussing scientific topics.

To me “invisible to the eye” means that the absence of sensory perception happens in the end organ of vision, not the areas of the brain that control consciousness. In reality, the information is visible to the eye. It’s an inaccurate title.

Reply to comment by jayhasbigvballs in A new study suggests that too much screen time during infancy may lead to changes in brain activity, as well as problems with executive functioning — the ability to stay focused and control impulses, behaviors, and emotions — in elementary school. by Wagamaga

100%. Though the study did acknowledge that screen time could be a proxy for some of these family characteristics. This means it's more nuanced though, and requires someone to embrace uncertainty. "Screen time bad" and controlling screen time is a simpler narrative for the masses.

This is more than likely one of the ways that serial killers, criminals etc seem to have a preternatural ability to just know who to rob/stalk.

I once watched this interview with a serial killer where he talked about being able to identify a potential victim by their *gait*...their walk.

Some people are closer to their 'lizard brain' than normies and it's kind of frightening.

Reply to Upon hearing recordings of wolf howls, older family dogs from more ancient breeds respond with longer howls — suggesting that genetic similarity with wolves affects dogs’ repertoire by marketrent

Did you know that most modern dog breeds don’t actually come from ancient wolf breeds? More so they come from a canine offshoot that’s closer to prehistoric hyenas than actual wolves?

Funny how that works, eh?

>>“Additionally, we found that breeds which howl more also show more stress-related behaviours in this situation. We assume that more ancient breeds, which are genetically closer to wolves, can process the information encoded in wolf howls better than modern breeds.

So the hypothesis is that these dogs are more stressed out by wolf howls because they understand what they are saying?

Reply to comment by deletedtothevoid in Study links Covid-19 vaccination hesitancy in Africa to the use of media platforms that spread misinformation. The spread of the Covid-19 pandemic in sub-Saharan Africa was accompanied by unprecedented and recurring waves of misinformation and disinformation. by Wagamaga

The published paper here:

https://onlinelibrary.wiley.com/doi/full/10.1002/jmv.28187?saml_referrer

It is notable the greatest increase happened after the introduction of the vaccine. Also the greatest increase was in the younger age groups, also known to be the case with the vaccine. (Yes, it is admitted by the CDC the vaxx causes heart issues. The only dispute is if the vaxx or COVID causes more.)

To confirm the link to the vaccine further the researchers should look at even younger age groups, such as under 25. If this also shows the worse heart effects, that strongly implies the vaccine is the cause.

Also, note the researchers did not record vaccine status. So they can not determine whether there is a vaccine link. Clearly, they should review the health records to include this data to make that determination.

Reply to comment by Glittering_Airport_3 in Children as young as 4 years old show evidence of a network in the brain found in adults that tackles difficult cognitive problems, a new fMRI study found. Researchers were surprised, thinking it may take longer for the multiple demand network to differentiate in humans. by geoff199

What? No the science is increasingly showing that brain development goes on for much longer than we thought. Out to 25 years and beyond, before which you are working with an under developed brain. It's why we make such poor decisions as young adults.

Kids are definitely just dumb little people, because their brains only have rudimentary systems like the one described here.

Kids have accelerated learning in some areas, like language, but go try and teach a child how to perform a new skill, like cooking, dancing, drawing, etc. Their brain lacks development in critical areas to perform even at a basic level without lots of development. Meanwhile adults, even not particularly quick ones, can easily perform the simple neural tasks required to learn these new skills.
