' You can't see this brain-computer interface.

Georgia Tech researchers have just shared a game-changing breakthrough: a nearly invisible brain-computer interface (BCI) that fits between hair follicles and sits just beneath the skin. No bulky headgear, no conductive gel – just a wireless sensor smaller than a millimeter, picking up brain signals with 96.4% accuracy, even while walking or running.

This ultra-tiny BCI uses microneedles to gently and painlessly penetrate the top layer of skin, getting closer to the brain’s electrical signals while avoiding hair – a smart workaround that drastically improves signal quality and reduces noise.

In tests, participants used this wearable sensor to control augmented reality video calls completely hands-free – just by focusing on visual cues. The interface tracked their neural activity for up to 12 hours straight, capturing which contact they looked at and helping them make or accept AR calls – all while staying fully mobile.
Why does this matter?

This technology could change daily life for people with disabilities, neurological conditions, or mobility challenges – giving them new ways to communicate, interact with technology, and regain independence. It also opens doors for everyday users to control digital devices with thought alone, potentially transforming how we engage with AR, VR, and smart environments.

Most BCI systems today are too bulky for daily use and struggle with movement. But this new design is small, stable, wireless, and wearable – opening doors to seamless brain-based control in real life.

This could be the future of human-machine connection – no wires, no discomfort, and no downtime.

' How to Find Direction Using Trees 🌳🧭

When lost without a compass, nature offers subtle clues to help you orient yourself. One such method is observing the way tree branches grow, particularly in temperate regions.

Key Concept:
🌞 The southern side of the tree (in the Northern Hemisphere) generally receives more sunlight throughout the year.
🌳 This causes branches on the south side to grow longer, fuller, and more horizontally, as they reach toward the light.
🌳 The northern side remains shaded, so branches are typically shorter, sparser, and more vertical.

How to Use:
1️⃣ Find a solitary tree in an open area — ideally not crowded by other trees.
2️⃣ Observe the branch growth pattern:
🔸 Longer, fuller branches → South
🔸 Shorter, thinner branches → North
3️⃣ Cross-check with other natural signs if possible:
🔸 Moss growth
🔸 Snow melt
🔸 Sun position (daytime), stars (night).

Important:
✅ Works best in the Northern Hemisphere.
✅ In the Southern Hemisphere, this pattern reverses (north-facing side gets more sunlight).
✅ Works better with older, open-grown trees.

Caution:
⚠️ Not foolproof — always cross-check with other navigation methods!

The High-Tech Battle for Your Brain with Joshua Stylman

I met Josh Stylman in March 2024 when I gave a briefing on the control grid to a group of freedom fighters assembled by Naomi Wolf. After the briefing, Josh approached me and humbly asked, “What can I do to help?” I suggested that he could make a major contribution by deep-diving the topic of mind control to help people understand how and why mind control is so fundamental to the construction of a control grid.

Josh was just the person to undertake such a task, having spent over three decades building and growing companies in the digital economy. Since the publication of his excellent four-part series titled “MKULTRA: The Hidden Hand” at his Substack (April/May 2025), I have not stopped recommending it.

' Rebecca Helm, a biologist and an assistant professor at the University of North Carolina, Asheville US writes:

Friendly neighborhood biologist here. I see a lot of people are talking about biological sexes and gender right now. Lots of folks make biological sex sex seem really simple. Well, since it’s so simple, let’s find the biological roots, shall we? Let’s talk about sex...[a thread]

If you know a bit about biology you will probably say that biological sex is caused by chromosomes, XX and you’re female, XY and you’re male. This is “chromosomal sex” but is it “biological sex”? Well...

Turns out there is only ONE GENE on the Y chromosome that really matters to sex. It’s called the SRY gene. During human embryonic development the SRY protein turns on male-associated genes. Having an SRY gene makes you “genetically male”. But is this “biological sex”?

Sometimes that SRY gene pops off the Y chromosome and over to an X chromosome. Surprise! So now you’ve got an X with an SRY and a Y without an SRY. What does this mean?

A Y with no SRY means physically you’re female, chromosomally you’re male (XY) and genetically you’re female (no SRY). An X with an SRY means you’re physically male, chromsomally female (XX) and genetically male (SRY). But biological sex is simple! There must be another answer...

Sex-related genes ultimately turn on hormones in specifics areas on the body, and reception of those hormones by cells throughout the body. Is this the root of “biological sex”??

“Hormonal male” means you produce ‘normal’ levels of male-associated hormones. Except some percentage of females will have higher levels of ‘male’ hormones than some percentage of males. Ditto ditto ‘female’ hormones. And...

...if you’re developing, your body may not produce enough hormones for your genetic sex. Leading you to be genetically male or female, chromosomally male or female, hormonally non-binary, and physically non-binary. Well, except cells have something to say about this...

Maybe cells are the answer to “biological sex”?? Right?? Cells have receptors that “hear” the signal from sex hormones. But sometimes those receptors don’t work. Like a mobile phone that’s on “do not disturb’. Call and cell, they will not answer.

What does this all mean?

It means you may be genetically male or female, chromosomally male or female, hormonally male/female/non-binary, with cells that may or may not hear the male/female/non-binary call, and all this leading to a body that can be male/non-binary/female.

Try out some combinations for yourself. Notice how confusing it gets? Can you point to what the absolute cause of biological sex is? Is it fair to judge people by it?

Of course you could try appealing to the numbers. “Most people are either male or female” you say. Except that as a biologist professor I will tell you...

The reason I don’t have my students look at their own chromosome in class is because people could learn that their chromosomal sex doesn’t match their physical sex, and learning that in the middle of a 10-point assignment is JUST NOT THE TIME.

Biological sex is complicated. Before you discriminate against someone on the basis of “biological sex” & identity, ask yourself: have you seen YOUR chromosomes? Do you know the genes of the people you love? The hormones of the people you work with? The state of their cells?

Since the answer will obviously be no, please be kind, respect people’s right to tell you who they are, and remember that you don’t have all the answers. Again: biology is complicated. Kindness and respect don’t have to be.

Note: Biological classifications exist. XX, XY, XXY XXYY and all manner of variation which is why sex isn't classified as binary. You can't have a binary classification system with more than two configurations even if two of those configurations are more common than others.

Biology is a shitshow. Be kind to people.

Many thanks to Traci Drake for finding this. '
