Friends, Lovers, and Microbes We may share more than good times with our friends and lovers.

Friends and lovers don’t just share advice and gossip. Amazingly, they also share microbes.

Can Probiotics Reduce Inflammation? Probiotics offer a drug-free way to treat inflammatory, autoimmune, and psychological disorders.

A lot of claims are made for probiotics, but can they really reduce inflammation?

Autism, Inflammation, and the Gut-Brain Axis Inflammation may play a surprising role in autistic behavior.

Is there is a microbial fingerprint of autism? By analyzing oral microbes, researchers can predict whether or not a child will develop autism with 80 percent accuracy.

Our gut is lined with a delicate layer of cells constantly battered by the pathogens that hitch a ride with each bite of food. The danger of infection is high, and that’s why some 80% of our immune system is concentrated around our digestive system.

I think we are in the middle of a huge shift in our understanding of our relationships with microbes. When we were kids, they were mostly regarded as harmful. Now we know that they are essential.

Emotional Resilience Emotions have a big impact on our health in times of stress. Use them to your advantage.

Laughing lowers your cortisol levels, resetting the immune system and altering gut microbes which then secrete molecules that further improve your mood.

Trials of the Firstborn It's not easy being the first kid in a family, but at least you get to inoculate your sibs.

Firstborns don’t have the luxury of a tested microbiota, typically passed down via sibling snot, to tutor their naΓ―ve immune system. That lack of education leads firstborns to overreact when exposed to new microbes.

Life Can Start Out Crappy Birth is full of microbes. That’s how nature planned it.

Your amniotic bubble having popped, you become exposed to the world. It’s your big day and everything is cold, dry and infectious. You, of course, are naked. You have no real consciousness yet, and you won't remember this day, but you know enough to cry.

Embryos Are Living In a Microbial World Embryos are full of potential, but very vulnerable. And microbes play a surprising role.

The idea that beneficial bacteria could be passed down by mothers is shocking to many doctors and scientists, who think that microbes associated with embryos are universally pathogenic. Yet researchers keep finding microbes wherever they look.

A Bed Fit for an Egg As an embryo develops, microbes play a mysterious role.

There is a connection between maternal depression and preterm birth. Surprisingly, even paternal depression can contribute to the preterm risk. However, there are hints that psychobiotic treatment can help minimize this effect.

Boy Meets Girl From an awkward and inauspicious meeting of two cells, a miracle happens.

Reproductive biology is pretty perfunctory when it comes to the male contribution. In many animals, the male is actually optional. If one isn't around, the mother can execute the whole business on her own in a process called parthenogenesis.

Epigenetics and Development If your genes represent the blueprint, epigenetics represent the construction crew.

Studies by John Cryan and Ted Dinan have demonstrated that beneficial microbe can cause epigenetic effects in the brain, favoring the growth of new nerve cells and enhancing cognition. Amazing science!

Could Mozart Change Your Microbes? We know music has an impact on our mood, but strangely enough, it also appears to change our gut microbes. Here's what we've learned.

The β€œMozart Effect” probably doesn’t make you smarter, but it may improve gut microbes, which is arguably stranger.

Pregnant Moms Need Pampering Pregnant mothers, like all of us, are stressed by modern life. This can have a long-term impact on their kids. Here are some tips for mitigating the stress.

Pregnant women who are stressed can suffer from an impaired microbiome. That can be passed down to their babies, affecting their weight, mood, and attitude, often into their teens or later.

OCD and the Gut-Brain Axis Could Your Gut Flora Be Fueling OCD?

The gut-brain axis explains the astonishing connections between the microbes that live in your gut and your brain issues, including OCD. When your gut microbes are out of balance, your mood may suffer, and your OCD may worsen.

Stressed moms have higher levels of cortisol, but also lower levels of oxytocin, the β€œcuddle hormone.” This one-two punch affects rat moms so deeply that they stop licking their pups. In that way, moms transfer stress to their pups.
