Is the carrot thing true? That sounds way too big of an effect

The study is here.

In 30 prospective studies with 9331 cases reporting plasma α-carotene levels, summary [relative risk] was 0.80.

10% reduction of less frequent intake of carrots seems more robustly backed by the data. Hopefully, some new study provides more info how big of an effect daily carrots have; see Figure 6.

Ok, I read the abstract, and honestly it's beyond my understanding of biology. I can usually understand how things interact at least on a basic level, I don't understand this one

Can you just dump your steam of consciousness understanding of this for me? Ideally I'd like to know how it might interact with cancer/the immune system, but your understanding of the statistics would also be appreciated. I'd like all your thoughts on this, don't worry about formatting or flow - if you just dump your thoughts on the topic it'll help me learn from it

If you don't understand the study itself or in general if you're interested in it, it's always a good idea to also read a good news report on it; see this and also this. They found carrot intake rather than beta-carotene, the focus of prior studies, has this association and figure 6 was just to show that they don't have much data on daily intake of a carrot or more.

Jeez, that's crazy... That's an insanely high effectiveness, but it does seem like there's something behind it. Guess I'm going to buy more carrots

That EEG helmet development is huge, even if it's only 40% accurate. The fact that it can be done at all just made it cross the threshold from sci-fi into just sci.

Higher accuracy was achieved in an earlier study where another team used large fMRI machines (it was featured in the version for May). There participants listened to audiobooks / speech while being in the large machine; I guess long training would be easier here but it's more limited since it's EEG. However, they claim they have exceeded 60% by now.

That hindawi bit at the bottom is important.

Hindawi, mdpi and frontiers are all suspect.
