Thought-to-Text Interfaces are Just Around the Corner

While mind-reading interfaces that convert thoughts to text sound like a dystopian sci-fi plot that could go horribly wrong disturbingly fast, the reality may not be so far away — or as fallible, either.

When you first hear “thought to text,” your knee-jerk response might be, “Uhh, no way. What if I have an intrusive thought that I don’t really mean to send? Or an impulse to text someone I know I shouldn’t?” But the most recent brain-computer face interface studies don’t rely on decoding your internal monologue or raw thoughts.

Rather, researchers have programmed a brain-computer interface that decodes “attempted handwriting movements” from motor cortex activity. This technology allows people who have been paralyzed for years to imagine handwriting and translate that into texting at speeds of 90 characters per minute with 94.1 percent accuracy, which is comparable to average smartphone typing speeds.

Furthermore, that accuracy climbs to 99 percent with general-purpose autocorrect.

Radiotrophic Fungi: The Fungus Among Us that Eat Radiation

Mushrooms: everybody’s favorite quirk of nature. From the psychedelic genus psilocybe and the Ophiocordyceps unilateralis that “mind control” ants, to the mushrooms that clean up oil spills and the mushrooms that may serve as planetary habitats, researchers have found yet another use for fungi: radiation protection.

“The greatest hazard for humans on deep-space exploration missions is radiation,” says a preliminary report in the bioRxiv journal. “Certain fungi thrive in high-radiation environments on Earth, such as the contamination radius of the Chernobyl Nuclear Power Plant… These organisms appear to perform radiosynthesis, using pigments known as melanin to convert gamma radiation into chemical energy. It is hypothesized that these organisms can be employed as a radiation shield to protect other lifeforms.”

Radiosynthesis runs parallel to photosynthesis — but instead of eating sunlight (UV radiation), these shrooms are eating gamma radiation. And it’s all possible through melanin, the same pigment that determines hair and skin color.

Moonshrooms: How Fungi Could Shape Life on Mars

NASA recently announced they’re exploring new, green ways to sustain human life in outer space through the help of our beloved fungal friends: mushrooms, or rather, their mycelia.
