I have two kids, so like all parents, I've been through some gross moments. Still, the all-natural baby decongestant Nosefrida the snotsucker brings out the giggling 15 year old in me. The picture tells the story: mom holds baby down like a prisoner and with one end of the tube in her mouth (or in my family, Dad), and the chamber tip firmly pressed onto bambino's schnozz, and snot is sucked. "Of course" product devotees will tell you, "it doesn't go up the tube, it gets captured in the chamber!!" But still. But still.
The Justice League Infant Socks 6-Pack ($15) is a pretty sweet new-baby gift, likely to be put to grateful use, and a delight when mix-and-matched (baby-socks being the sort of thing that disappear in the wash because they crumple to the size of a spitball). I still harbor free-floating guilt about some of the awesome baby-clothes we got when Poesy was born, because in the hurly-burly of consta-pooping and grosteque sleeplessness, a ton of them ended up being outgrown before they were worn. The exceptions: socks and onesies.
Nobody knows what causes Sudden Infant Death Syndrome. There are a many factors linked by correlation and lots of things that, again, correlate to a reduced risk. But the actual cause (or causes) have been elusive. Fascinatingly, research from Seattle Children's Hospital suggests that inner ear dysfunction and hearing impairment might play a role in some SIDS deaths. Sleeping mice with inner ear problems have a harder time waking themselves when they're positioned in a way that makes it hard to breathe. Meanwhile, a surprising number of SIDS victims were diagnosed with hearing problems.
TIL: There are studies that suggest new babies really do smell different, and seem to trigger special brain chemical pathways in women. But, simultaneously, the smells we more consciously associate with "new baby" — i.e., the new baby smell used in baby products and baby-fresh scents — varies widely by culture. Make of this what you will.
I'm 38 weeks pregnant now. Two weeks ago, my husband and I both got Tdap vaccines — tetanus, diphtheria, and pertussis. This despite the fact that we've both gotten Tdaps relatively recently, within the last six years, thanks to a home renovation lifestyle that involves regular exposure to rusty nails.
So why re-up on the Tdap before the birth of our baby? It's all about the pertussis. Also called whooping cough, pertussis is particularly hard on infants. Pre-vaccine, it killed 4000 Americans every year, and most of them were new babies — and infections are on the rise in this country, so there's actually a reasonable risk of a newborn coming into contact with the bacteria that causes pertussis. But the larger problem is with the pertussis vaccine, itself. It doesn't have the staying power it once did. A little over 20 years ago, we switched the formulation for pertussis vaccines. There were good reasons for doing that — the "new" formula has fewer side effects. But it also doesn't seem to protect people as well for as long. In fact, the protection starts to wear off within a year of vaccination.
The Skinner Box, as applied to human infants, was not what you think it was. Psychologist B.F. Skinner did not raise his daughter inside a box without human contact. Nor did she later grow up to be crazy and commit suicide because of said lack of contact. In fact, just a few years ago, Deborah Skinner Buzan wrote a column for The Guardian debunking those powerful urban legends herself.
Instead, what Skinner did was build his daughter the sort of crib that you might expect a scientist raised in the era of mid-20th-century Popular Science-style scientific futurism and convenience to build. He called it the "Air-Crib" and it was designed to maintain a perfectly comfortable temperature, provide baby Deborah with built-in toys to keep her entertained, be simple to clean, and make it easier to stick to the "cry it out" and heavily regimented feeding/sleeping schedules that were, at the time, standard parenting advice.
An octopus' life is short — two years is a pretty common lifespan — and heavily focused on reproduction. They only get one shot at carrying on the genetic lineage and die soon after breeding. Babies are born not by the two, or tens, or even hundreds. Instead, tens of thousands of octopus siblings enter the world all at once — tiny, translucent hatchlings that ride the waves and try not to die more quickly than they already must.
Popular Science has a great (and occasionally horrifying) slideshow of gadgets it once suggested were essential for enlightened, tech-minded parents. A lot of the inventions merely look way sketchy. For instance, the infant-sized "sleeping porch" that is actually a screened box bolted into an apartment window frame is probably mounted well enough that it's not going to kill anybody. It's just that, from the vantage point of a 100 years later, it seems a little disturbing to stick your baby into something that looks like a large AC window unit.
A full day after the birth of her cub, panda Mei Xiang gave birth to a second, stillborn, cub. The first cub is still doing great. But the second one had developmental abnormalities and wasn't ever really going to live.
This baby nautilus emerged this week from an egg laid last November at San Diego's Birch Aquarium. For this tiny cephalopod, the process of being born took not hours, or even days, but weeks. The ZooBorns site has a series of photos that show how the nautilus slooooooowly emerged from the egg.
As a woman, you do become less fertile as you get older, eventually culminating in menopause and the end of your potential babymaking years. But what does "less fertile" mean, and at what age, and how quickly does the drop-off in fertility happen?
According to this really fascinating piece by Jean Twenge at The Atlantic, some of the commonly cited scare stats — that one in three women ages 35 to 39 will not be pregnant after a year of trying, say — are based on extremely old data collected from historical birth records that don't necessarily reflect what's happening with real women who are alive right now. That statistic mentioned above, for instance, comes from French records (likely those collected by local church baptismal registries) for the years 1670 to 1830.
That matters because fertility is affected by things like quality of nutrition, infection rates, and even childhood illnesses — all of which have changed drastically for the average Western woman since the 19th century.
Look at more modern records, and the outlook for post-30 babymaking is completely different.
This article by Monique Robinson is interesting — not because it tells you anything particularly useful about what you can do before conception to influence the sex of your child, but because it provides a rundown of the many random correlations studies have linked to fetal sex determination over the years. From eating cereal to being a billionaire's kid, it's an intriguing look at how easy it is to find patterns, even when those patterns may (or may not) be totally meaningless.
I've been linking Double X Science a lot lately. That's because they're great. It's rare to get such smart, fascinating, science-centered discussion about female anatomy and reproductive issues that goes beyond the surface dressing we all already kind of know. Case in point: This piece by Emily Willingham about the development of the human heart in utero. You've probably heard at one point or another that a fetus' heart starts beating around 6 weeks (an age which is, by the way, calculated from the date of the mother's last period, NOT from the date of actual conception; so the fetus itself is really only about 4 weeks old at this point, and its mother only missed her period two weeks ago). But what's the heart actually like at that point? Turns out, absolutely nothing like what you imagine. Very cool stuff.
If you think about lactation too hard, it starts to seem a little strange — like the biological equivalent of saying the word "that" over and over until it's just a weird sound you're making. But, writes Nicholas Day at Slate, the sort of existential weirdness of breast milk is nothing compared to what's going on in the stuff at a chemical level. For instance, breast milk contains sugars that aren't actually digestible by human infants. That's because they aren't meant for the infant, itself. Rather, your breast milk is helpfully feeding your baby's intestinal bacteria. Freakier still: In monkeys, the chemical composition of breast milk can change, depending on factors like your baby's sex and whether your baby is showing signs of illness.
There is definitely a seasonality to human births, writes Beth Skwarecki at Double X Science. The complicated bit is that human baby season isn't necessarily the same (or as strongly expressed) from place to place and culture to culture. In the United States, significantly more babies are born in July, August, and September. Meanwhile, in Europe, babies seem to make their way into the world in spring. So there's clearly a cultural component to this — but culture doesn't explain it, entirely. Skwarecki's piece explores a messy place where culture, genetics, and circadian rhythms intersect.
National Geographic's Enric Sala took this photo during an expedition in Gabon. He and another researcher were using a remote operated vehicle to explore the ocean off the coast of that country's Loango National Park.
When we picked up the shell from the ROV’s arm, to our surprise, a small octopus came out of the shell. It was a female that laid her eggs inside the shell. We put shell and octopus in a tank with seawater, and after one minute thousands of octopus larvae started to stream out of the shell. The octopus eggs were hatching! That was the first time we had observed such a magnificent show. The larvae were changing coloration from transparent with dark spots to brown, and swimming like squid – although on a millimeter scale.
An 18 month-old toddler was ordered off a plane Tuesday at Ft. Lauderdale airport, after TSA representatives told airline employees they wanted to "speak" to her.
Riyanna's father was flabbergasted. "It's absurd," he said. "It made no sense. Why would an 18-month-old child be on a no-fly list?" Riyanna's parents, who asked not to be identified, said they think they know the answer to that question. They believe they were profiled because they are both of Middle Eastern descent.
They were detained for 30 minutes; no apology was forthcoming for the humiliating theatrics. The airline, JetBlue, says that the TSA asked for the baby's removal and that both it and the agency were investigating. The TSA said, however, that the event was an "airline issue" and that it was not investigating it at all.
Here's an amazing feel-good video with which to end your week, via the National Science Foundation. The really awesome footage starts around a minute and a half in.
"James C. (Cole) Galloway, associate professor of physical therapy, and Sunil Agrawal, professor of mechanical engineering -- have outfitted kid-size robots to provide mobility to children who are unable to fully explore the world on their own."
The robotic assistance devices are designed to help infants whose mobility and independence is limited by conditions such as autism, spina bifida, muscular dystrophy, Down syndrome, and cerebral palsy.
I understand that these will be among the many exhibits on display at the USA Science Fest at the Washington, DC Convention Center on Sat., April 28th. Babies probably not included.
