Thumb-sucking and Nail-biting Reduce Common Allergies?

Thumb-sucking and Nail-biting Reduce Common Allergies?

Thumb sucking and nail-biting early in life may reduce allergies later in life. Linus’ thumb-sucking habit just might reduce his risk of common allergies. An article in Pediatrics found that kids who had their fingers in their mouths at ages 5, 7, 9, and 11 years old were less likely to have a reaction to a skin prick test for allergies later in life (ages 13 and 32 years) [1]. Study participants were pricked with common allergens including: house dust mites, grass, cat, dog, horse, wool, and several fungi at ages 13 and 32.

Microbial Media and Bacterial Biofilms: #SciComm Round-up

Microbial Media and Bacterial Biofilms: #SciComm Round-up

So many excellent new videos and articles written to a general audience are being produced so frequently. Here I’m rounding up my favorites from May. Bacterial Biofilms TED-Ed (Scott Chimileski and Roberto Kolter): “The microbial jungles all over the place (and you).” In nature, yourself included, bacteria live in cities of mucus they and sometimes other microbes. This video does an awesome job of talking about the importance of biofilms for bacterial survival. It is a little surprising that they didn’t mention antibiotic resistance or issues with biofilms on medical devices, but it was refreshing that it focused more on environmental bacteria instead of human issues with pathogens. Gut Microbiome FiveThirtyEight: “Gut Science” – includes articles on probiotics, gut science’s WIERD bias, constipation worries, and more. There’s even a video “What Your Poop Says About You” General Microbiome PhD Comics  and Elaine Hsiao’s video “The HIDDEN World of Microbiomes” gets a 2 pili up rating for producing an excellent, informative video. I love that this video includes environmental microbiomes as well as the human microbiome. Certainly, and perhaps coincidentally?, this video was produced in partnership with the Kavli Foundation and released a few weeks before the National Microbiome Initiative. If this is the

It’s All About the Breast Milk Sugars, Baby

It’s All About the Breast Milk Sugars, Baby

Helpful infant gut bacterium, Bifidobacterium infantis, uses special breast milk sugars to grow that other bacteria can’t use. Breast Milk Sugars Don’t Feed the Infant As parents we often try to limit sugar for our kids. However, with breast milk – the sugars are essential food for helpful bacteria that grow in an infant’s gut. Along with fats, water, antioxidants from mom’s diet, antibodies, and other compounds, breast milk has a diversity of complex carbohydrate sugars. Called human milk oligosaccharides (HMO), these chains of carbohydrates bonded together are difficult to break apart. Humans do not make the enzymes that can break these breast milk sugar bonds [1, 2]. Our helpful gut bacteria do [3-6]. Infants and most gut bacteria don’t have the enzymes in their guts to digest the sugars that dominate human breast milk. The beneficial bacterium, Bifidobacterium infantis, uses enzyme Endo BI-1 for breaking sugars to use for food. This may explain why B. infantis dominates the gut of breast fed babies. HMO sugars are extremely different from their refined and over-processed cousins that we use to sweeten our drinks and solid foods. Refined and processed sugars are primarily simple carbohydrates made of a few carbon molecules bound together

Time is Running Out for “Culture as Medium”

Time is Running Out for “Culture as Medium”

  If you are in the Baltimore area between now and May 20th and haven’t experienced an aspect of the science-art exhibit – Culture as Medium – time is running out! Culture as Medium, celebrates Baltimore as a growing and thriving biotechnology and artistic hot spot, while encompassing the complexity and diversity of the city. The exhibit explores the intersection of art and science through exhibiting art by internationally recognized scientists and artists, as well as several performance art/science opportunities. Culture as Medium is an “evolving” exhibit inviting visitors to explore and merge the boundaries of art and science, the visible and invisible portions of our world. Opening at the Motor House Curated by Margaret MacDonald of the Maryland Institute of Art (MICA), Culture as Medium, spans different areas of the city. The first installation of the exhibit opened at the Motor House in the Station North Arts and Entertainment District on April 1st. Dr. François Joseph Lapointe from the University of Montreal conducted a performance “microbiome selfie” collecting microbiome samples from his tongue every 10 minutes after eating kimchi for an hour. Kimchi was chosen for his food microbiome selfie to honor the Koren population in the surrounding area. Visitors

Book Review: The Invisible War

Book Review: The Invisible War

The graphic novel “The Invisible War: A Tale on Two Scales” tells stories of the macroscopic (nurses) and microscopic (bacteriophage) heroes fighting dysentery at the Western Front of World War I. Interweaving Views of Tales, Scales, and Heroes “The Invisible War: A Tale of Two Scales” works its magic, interweaving the stories of two rarely discussed topics – dysentery and bacteriophage – and two rarely intertwined fields of study – science and history. The resulting story is a rich tapestry full of action and information at both the macroscopic and microscopic levels. “The Invisible War” tells about Annie, a nurse at a field hospital at the Western Front of World War I. In her nursing experience, Annie has learned the symptoms and consequences of dysentery, at a time when the cause wasn’t well understood and no reliable cure was known.
