Foreign DNA trapped inside you may be changing your behavior
There may be another human’s DNA trapped inside of you. This foreign DNA could potentially influence which hand is dominant or the propensity to develop Alzheimer’s.
There may be another human’s DNA trapped inside of you. While it may sound like a weird science sequel to The Exorcist, according to Peter Kramer at the University of Padua, “A very large number of different human and non-human individuals are all incessantly struggling inside us for control.”
Kramer and his colleague Paola Bressan just published a paper about this strange phenomenon — microchimerism — that influences our behavior. Basically, we pick up DNA perhaps in the womb from a twin, a subsumed twin, an older sibling, our mothers, or later in life from a pregnancy. In one study, 63 per cent of women who’d had children were harboring male cells in their brains.

While it’s been studied that the bacteria in our guts can influence everything from our mood to our appetites, less is known about how this shadow human DNA may sway our decisions and feelings. This foreign DNA could potentially influence which hand is dominant or the propensity to develop Alzheimer’s. In one study of Danish women who’d been pregnant, epidemiologists determined that the leftover Y chromosomes improved the overall health of the women.
What’s stranger still is that microchimerism of male cells in women occurred even when they’d never given birth to a son — the DNA possibly transferred by an older brother or even sexual intercourse with a man. It seems then that the human body is far from fixed at birth and instead picks up DNA the way our browser does cookies.
Bryan Sykes, founder of Oxford Genetics, says everyone should be proud of their own genes.
Research in plant neurobiology shows that plants have senses, intelligence and emotions.
- The field of plant neurobiology studies the complex behavior of plants.
- Plants were found to have 15-20 senses, including many like humans.
- Some argue that plants may have awareness and intelligence, while detractors persist.
E-cigarettes may be safer than traditional cigarettes, but they come with their own risks.
- A new study used an MRI machine to examine how vaping e-cigarettes affects users' cardiovascular systems immediately after inhalation.
- The results showed that vaping causes impaired circulation, stiffer arteries and less oxygen in their blood.
- The new study adds to a growing body of research showing that e-cigarettes – while likely safer than traditional cigarettes – are far from harmless.
Since the idea of locality is dead, space itself may not be an aloof vacuum: Something welds things together, even at great distances.
- Realists believe that there is an exactly understandable way the world is — one that describes processes independent of our intervention. Anti-realists, however, believe realism is too ambitious — too hard. They believe we pragmatically describe our interactions with nature — not truths that are independent of us.
- In nature, properties of Particle B may be depend on what we choose to measure or manipulate with Particle A, even at great distances.
- In quantum mechanics, there is no explanation for this. "It just comes out that way," says Smolin. Realists struggle with this because it would imply certain things can travel faster than light, which still seems improbable.
