New Bacteria Could Make You Poop Rainbows

In 2009, students at Cambridge University genetically engineered E. coli bacteria, adding DNA sequences in order to create colors visible to the naked eye (standard E. coli does not have a pigment). The students called this new strain E. chromi, and it has limited uses today, primarily related to detecting pollution or other chemicals -- if the bacteria detects a chemical, it changes color.

That's all well and good, but how do we take this and go nuts with it, creating a Terminator-like dystopian horrorscape? I'm so glad you asked. In the short film below (which is largely fictional), an example is given in which an advanced form of this bacteria could be ingested by humans, and it could then identify illnesses within the GI tract...which you'd learn about after pooping a rainbow of bacteria-laden diagnostic material. (Oh, were you eating? I should have warned you.)

I should emphasize: this is a speculative art project based on some limited real-world science. But who among us does not dream of a poop-rainbow-filled tomorrow? I, for one, welcome our new bacterial overlords.

This Giant Baking-Soda-and-Vinegar Volcano Tops Any Science Fair Project

The baking-soda-and-vinegar volcano, an elementary school staple, has received a super-sized upgrade. As Atlas Obscura reports, the Oregon Museum of Science and Industry revealed their 34-feet version of the classic science project in celebration of their new Pompeii exhibition.

The mountainous structure relied on the same chemical reaction as smaller artificial volcanoes, but this time the reaction was recreated on a much larger scale. After wrapping the three-story scaffolding with brown tarp, museum staff filled it with 66 gallons of vinegar and 50 gallons of baking soda, plus water and red food dye to create two geysers of pink liquid.

While it's still a fraction of the height of Mount Vesuvius, the volcano towers over anything you’d find in an elementary school science fair. After showing off the project in front of a crowd of 3000 people, the museum plans to submit its creation to the Guinness World Records committee for consideration.

Science Explains Why You're Not a Morning Person

Can't get out of bed in the morning? Allow science to tell you why—and whether or not you can change that.

I’m awful in the mornings. Can science fix me?

Maybe not, but it can explain why you’re such a sleepyhead (which may or may not be of interest to your boss). “There are morning people and evening people,” says Sonia Ancoli-Israel, director of education at UC-San Diego’s Sleep Medicine Center. “We call them larks and owls.” Which one you are has to do with your circadian system.

How does my circadian system work?

A region of 20,000 nerve cells in your brain called the suprachiasmatic nucleus keeps your body on schedule throughout the day, regulating everything from hormone levels to when you digest food. And, of course, when you feel sleepy.

How does that explain me?

Larks are “phase advanced,” meaning they feel tired early in the evening. Owls are “phase delayed”—a pattern most common in teens and young adults—and don’t feel tired until late at night.

Should I be concerned?

Larks do have a mental edge. In 2013, a study found that early and late risers have structurally different brains. Larks have more quality white matter, which helps nerve cells communicate.

Can I change that?

A little bit. Your circadian rhythm changes over your lifetime. Babies wake at dawn, while teenagers can’t get out of bed before noon. As adults age, mornings typically get easier. You can also hack your clock by sticking to a regimented sleep schedule and avoiding light before bed. Light receptors in the eye tell your brain when to call it a night.

Can I blame this on genetics?

You bet! In 2012, scientists discovered a single nucleotide near a gene called “Period 1” that determines whether you’re an owl, a lark, or in between.
