Beer Made With 45 Million Year Old Yeast?

The other day I came across a Reddit post entitled: “Beer Made With 45 Million-Year-Old Yeast Found in Amber.”

And I was intrigued.

The link led to an Indiegogo campaign from the Fossil Fuels Brewing Co. aiming to raise money to further their production of beer made with ancient yeast. As the story goes, the idea was born after the “chance discovery of a beautiful amber stone, replete with a 45 million year old leaf, and a single yeast spore – still alive and itching to make beer.”

Tracking the Mighty Sabertooths

This is a modern Tiger print.

Did you hear about those newly-discovered saber-toothed cat footprints? If not, check it out over at Science (there’s an awesome picture). The tracks are apparently up to 19cm across – bigger than a Bengal tiger’s! They were discovered in Argentina (because some countries have all the luck these days), and presented at a conference in May. These tracks probably belonged to a species of Smilodon, the most famous saber-toothed cats of them all.

Sabertooth tracks are rare, but these aren’t the first. I’ll get more into that later, but first: what exactly is a saber-toothed cat? Are they really cats anyway?

Island of the Tiny People

In 2003, the field of human evolution was rocked by the discovery of “hobbits,” an ancient species of human relatives who stood barely more than a meter tall. Named Homo floresiensis, they lived on the Indonesian island of Flores, and for years researchers argued over whether they represented the first-known human case of “island dwarfism” or if these ancient individuals had some sort of disease causing their short stature. If they were diseased, what disease did they have? If they were a legitimate species, where did they come from?

The disease hypothesis has mostly fallen out of favor. Numerous studies have countered suggestions that H. floresiensis had microcephaly or hypothyroidism or other proposed conditions. On Wednesday, a new study provided evidence against Down Syndrome being responsible for the fossils’ appearance. So it seems the “hobbits” were their own species, but that leaves still many questions.

The Earth's Deepest Scars

No matter how thoroughly researched and well-understood a scientific theory is, there’s always room for improvement, always something we missed. Plate tectonics is one of the most powerful and comprehensive theories in modern science, but according to a new study out today, we may have missed an important piece of the geologic puzzle. According to this research, tectonic activity may be controlled by forces deeper below the surface than we’ve realized.

Plate tectonics theory explains how the Earth’s crust moves and changes. The crust isn’t a solid shell over the Earth, it’s broken into fragments: plates. Each plate butts right up against all the surrounding plates, so there’s no space in between, but they can rotate in place, or shift like conveyor belts, sliding and grinding past each other, into each other, or underneath each other. Boundaries between plates are areas of massive geologic activity. Where plates move together, they form massive mountains or deep trenches; where plates pull apart, volcanic activity creates new crust. The surface of the Earth is constantly shaking, shifting, and deforming, mostly at these boundaries.

This is a map of the major tectonic plates of the Earth.
Notice the places where the plates meet - those are the very active plate boundaries.

"Saurian" is Already the Best Dinosaur Video Game of All Time

As popular as dinosaurs are, they’ve been surprisingly under-developed in video games. Most “dinosaur video games” – Primal Carnage, Turok, ARK, etc. – fun as they may be, feature re-hashed versions of misinformed prehistoric beasts being hunted and/or fought and/or ridden by humans. And just as the same-y anachronistic lizard-monsters of Jurassic World didn’t cut it for a lot of dino-fans, the ancient beasts of those video games similarly fail to impress. They just don’t feel like real dinosaurs.

And then there's Saurian. Watch this video:

Dinosaurs don't get realer than that.
