An Alzheimer’s vaccine might be possible

Posted by in categories: biotech/medical, neuroscience

The cause of Alzheimer’s is still not fully understood, but we might be able to vaccinate against it anyway.

We might have Alzheimer’s all wrong

Posted by in categories: biotech/medical, neuroscience

For over 30 years, toxic proteins were thought to cause Alzheimer’s. However, recent studies suggest it might be metabolic reprogramming.

Brain stimulation boosts memory for at least a month

Posted by in category: neuroscience

Brain zapping, or more technically “transcranial alternating current stimulation” (tACS), can improve memory recall in people aged 65 to 88.

Is IQ a load of BS?

Posted by in category: futurism

What’s IQ good for?

Just because something has, historically, been used for immense evil doesn’t necessarily mean it is, in itself, unfit for purpose. So, with what we know today, how far should IQ be trusted?

Edible electronics: When will we be eating technology?

Posted by in categories: biotech/medical, health

Americans endlessly chatter about what to eat. Low fat, high protein, vegan, ketogenic — but what about electronic? Since the turn of the 21st century, a dedicated group of scientists, engineers, and technologists has been trying to create edible electronics, not necessarily for human nutrition, but rather for medical purposes.

Electronic devices composed of digestible materials that gradually break down in the body over a matter of days could precisely deliver medication inside the body and measure drug uptake. They could monitor symptoms of gastrointestinal disorders and the gut microbiome. They could allow doctors to remotely observe patients’ internal health without a visit to the hospital, further enhancing the telehealth revolution and allowing more people access to healthcare.

10 Paradoxes That Will Stretch Your Mind

Posted by in categories: alien life, existential risks, physics

As in physics, paradoxes in biology really are just unsolved puzzles. Enter Peto’s paradox. Biologist Richard Peto noticed in the 1970s that mice had a much higher rate of cancer than humans do, which doesn’t make any sense. Humans have over 1,000 times as many cells as mice, and cancer is simply a rogue cell that goes on multiplying out of control. One would expect humans to be more likely to get cancer than smaller creatures such as mice. This paradox occurs across all species, too: blue whales are much less likely to get cancer than humans, even though they have many more cells in their bodies.
