Unfortunately, science education research and practice tend to exist in parallel universes. If we care about science education, we have to face the research-practice divide.

Flashback Friday: Here's a list of what's currently living in your belly button. - Seriously, Science? | Exploring Life Course Resources | Scoop.it
Have you ever wondered what exactly is inside your belly button? Well, besides the lint (which is mostly derived from actual lint), there is a whole ecosystem of microorganisms that call the navel their home. The authors of this study used DNA sequencing to identify these organisms, determining that the belly button microbiome is dominated …

“Natural” doesn’t necessarily mean better | Exploring Life Course Resources | Scoop.it
If there’s one fallacy that grips the brains of proponents of “natural healing,” “holistic medicine,” or, as the vast majority of it is, quackery, it’s an appeal to nature. Basically, the idea that underlies the appeal to nature is a profane worship of nature as being, in essence, perfect, with anything humans do that is…

Newly Created Fungus Is Part Human, Part Yeast : DNews

Newly Created Fungus Is Part Human, Part Yeast : DNews | Exploring Life Course Resources | Scoop.it

living yeast that is part human and part fungus has been engineered by scientists in a feat that shows how, despite a billion years of evolution separating humans from yeast, the two species share hundreds of genes in common.

Those genes remain, in part, from the last common ancestor of humans and yeast.

“Cells use a common set of parts and those parts, even after a billion years of independent evolution, are swappable,” Edward Marcotte, a professor at The University of Texas at Austin, said in a press release.

“It’s a beautiful demonstration of the common heritage of all living things — to be able to take DNA from a human and replace the matching DNA in a yeast cell and have it successfully support the life of the cell.”

That’s just what Marcotte and his colleagues did, as they describe in their study published in the journal Science. Although yeast (such as the Baker’s yeast that might be in your refrigerator now) consists of a single cell and humans have trillions of cells organized into complex systems, multiple genes are shared between the two.

Of those, about 450 are critical for yeast’s survival, so the researchers removed the yeast version of each one and replaced it with the human version and waited to see whether the yeast would die.

They wound up creating hundreds of new strains of yeast, each with a single human gene. About half of these resulted in an organism that could survive and reproduce.

While this might sound like an eerie Frankenstein-like experiment, the goal is to produce a new way of researching human genetic diseases caused by mutations.

It’s actually cutting edge research, since the technique could help to reduce or even eliminate testing on live animals.

Another benefit is that the testing could lead to treatments designed for a particular individual. For example, researchers might insert precise versions of a human gene mutation into yeast and then expose the yeast to different drugs to test new therapies. As a result, the treatments could be tailored to a person’s precise genetic mutation.

What Lives Inside Your Navel

A similar technique could be used to test treatments for other animals too, such as dogs and cats.

“We could find out if one of the standard treatments would work on your particular version of the gene or if maybe another drug would be even better,” explained co-author Claus Wilke.

Multiple genes might also be able to be inserted at once into yeast, permitting researchers to examine more complete systems as opposed to just a single mutated gene.

“This work is basically showing that you can take a fuel injector from a tractor and swap it for a fuel injector in your Toyota and it will still work, more or less, because they’re both fuel injectors,” Marcotte said.

The infant gut microbiome: New studies on its origins and how it's knocked out of balance | Exploring Life Course Resources | Scoop.it
A fecal sample analysis of 98 Swedish infants over the first year of life found a connection between the development of a child's gut microbiome and the way he or she is delivered. Babies born via C-section had gut bacteria that showed significantly less resemblance to their mothers compared to those that were delivered vaginally.
