Unlike the embryos of other vertebrates, early snake embryos coil as they get longer, typically forming clockwise spirals.

A new study offers an explanation for why embryonic snakes go through these contortions—and why they tend to curve in one direction.

Digging Into History: Students Sort Shark Tooth Hill Fossils!

Excitement is running high as students dive hands-on into the prehistoric past!

Using material from California's legendary Shark Tooth Hill in the Central Valley, students are carefully sorting through matrix to discover ancient marine fossils.

What is Shark Tooth Hill?

Located near Bakersfield, California, the Round Mountain Silt formation (commonly known as Shark Tooth Hill) dates back roughly 15 to 16 million years to the middle Miocene epoch. Back then, a rich marine sea covered much of the Central Valley.

What Are They Finding?

Shark Teeth: Including massive teeth from the extinct Megalodon relative, the Megallamna or ancient great whites (Carcharodon hastalis).

Ray & Skate Dental Plates: Fossilized pavement teeth from ancient rays.

Marine Mammal Bones: Fragments of ancient whales, sea lions, and desmostylians.

Fun Fact: Shark Tooth Hill is one of the densest bonebeds in North America, preserving millions of marine creatures from a time when California's climate and coastline looked completely different!

Bringing paleontology into the classroom (or the lab) is an incredible way to spark curiosity about earth science, evolution, and California's prehistoric ecosystems.

What’s the coolest fossil you’ve ever found?

A personalized mRNA cancer vaccine has become the first of its kind to clear a Phase 3 clinical trial, putting it on a potential path toward FDA approval.

Unlike traditional cancer treatments that use a one-size-fits-all approach, researchers tailor each vaccine to target a patient’s cancer cells, giving the immune system the genetic instructions it needs to identify and attack the tumor. The trial included more than 1,000 melanoma patients at risk of recurrence, offering researchers insights into how this treatment could fit into cancer care. https://on.natgeo.com/5pdCvB

The Family in the Wood

Pick up a rotting log sometime. Not a punky one, not one that crumbles to powder when you lift it. Look for the solid kind, the one that still holds its shape but gives a little when you press your thumb in. There is a world inside it.

If you are lucky, you will find bess beetles. They are big for beetles, shiny and black and deliberate. They do not scatter when you expose them the way most insects do. They pause. They seem, for a moment, to consider you.

What is happening inside that log is something we do not usually expect from beetles. There is a family there. A mother and a father, and if the season is right, larvae curled in chambers of chewed wood, pale and soft, waiting. The adults have already done the difficult task. They chew the rotting wood into a fine, moist pulp and the larvae consume its cellulose fibers and the fungi woven through them. A bess beetle larva cannot manage raw wood on its own. It needs what its parents have already transformed.

Rachel Carson wrote that the more clearly we can focus our attention on the wonders and realities of the universe around us, the less taste we shall have for destruction. I think she would have loved this log. She would have seen past the rot to the industry inside it, to the economy of care that holds the whole small civilization together.

The beetles also speak to each other. They stridulate, rub their wings against their bodies, and the sounds are different depending on who is making them and why. The larvae call to the adults. The adults answer. Fourteen distinct signals, some say. It is a language we are only beginning to hear.

If you press your ear close to the log, you can hear the chewing. It is a small, steady sound. It does not stop.

The older offspring stay too. Adult sons and daughters that have already completed their own metamorphosis remain in the colony, helping to feed the newer larvae and to construct the protective cases where the next generation will transform.

When the time comes to pupate, the larva does not simply curl up and wait. It builds. Working with the adult beside it, it packs chewed wood and frass, digested wood passed through a body and transformed, into a tight case around itself. The material is fibrous and dense, faintly damp, smelling of the log's deep interior. The adult piles debris against the outside until the pupa is sealed in something snug and wrought, a small room made of what the forest has already used and given back.

Mary Oliver would have knelt down. She would have gotten her knees dirty. She would have asked the question she always asked, the one that cuts right through: what is it you plan to do with your one wild and precious life? The bess beetle does not hesitate. It tends the young. It chews the wood. It answers when called. It builds the case around the pupa with its own body and its own labor.

My childhood mentor, Lola would have knelt down beside you. She would have said: what do you notice? She would have waited, really waited, while you looked. She would have asked you what questions were rising up in you, and she would have treated every one of them as worthy. She would have found in this beetle, this brilliantly black, deliberate, shining creature going about its subtle work, something worth honoring. Not because it was rare. Not because it was beautiful in any obvious way. But because it was alive, and doing what it was made to do, and doing it with what can only be called devotion.

That would have been her gift to you. Not the answer. The looking.

🏜️ Canyon Makers in the Making!

Yesterday our young geologists got their hands on one of geology’s biggest mysteries. How did the Grand Canyon form?

Using just a paint tray and sand, students modeled the Spillover Theory: a prehistoric lake called Lake Bidahochi slowly filled with water from the ancestral Colorado River until one day, it spilled over. That spill, repeated and magnified over millions of years, carved one of the most spectacular landscapes on Earth.

And here’s the exciting part — this isn’t just an old idea. In April 2026, USGS scientists published brand-new research in the journal Science confirming that Lake Bidahochi played a direct role in shaping the Grand Canyon and the entire Colorado River system. Our students were modeling cutting-edge geology! 🌊🪨

Science is never finished. There’s always more to discover and sometimes the biggest answers start with a tray of sand and a good question.

Shout out to our SSW geologist Kelly Henry Staab for introducing the Spillover Theory to me during the Covid shutdown and for designing the hands-on experience for our students. 😀

A Living Legend Meets Its Match! 🐟🗿

​Check out this deep-sea celebrity!

My Coelacanth (pronounced see-la-kanth) plushie is taking a well-deserved nap on a bed of actual fossils. It’s a poetic pairing: a "living fossil" resting on the remnants of a world that time forgot.

​The Fish That Fooled the World

​For decades, scientists thought these guys went extinct 66 million years ago along with the dinosaurs. They were known only from stone imprints until a legendary woman named Marjorie Courtenay-Latimer changed history in 1938.

​Marjorie, a young museum curator in South Africa, was rummaging through a fisherman's "pile of junk fish" when she spotted a flash of iridescent blue. Despite the local mortuary refusing to store the "stinky fish" and her boss telling her it was just a common cod, she followed her gut.

​When an expert finally saw her sketches, he said it felt like a "bomb burst in his brain." She had found a ghost! To honor her, the scientific name is officially Latimeria chalumnae.

​Why This Fish is Totally Marvelous:

​Lobed Fins: Those chunky fins have bones structurally similar to our own arms and legs. They’re basically the cousins of the first fish that crawled onto land!

​Electrosensory Snout: They have a "rostral organ" in their nose to detect the electrical impulses of prey in the pitch black of the ocean.

​Late Bloomers: They can live for 100 years and don't even hit "puberty" until they're about 40.

​From a stinky pile of fish in 1938 to a cozy spot on my desk today—long live the Coelacanth! 🌊✨

🪱✨ The worm's MAGIC COLLAR! ✨🪱

Today our young naturalists made one of the best discoveries of the year — the clitellum.

That little raised band toward the front of the worm's body? The kids called it the magic collar the moment they spotted it. And honestly? They're not wrong. The clitellum produces a ring that slides off the worm's body and forms a cocoon — containing eggs, stored s***m, and nutrients for the developing embryos inside. That modest-looking collar builds a tiny, self-contained nursery.

Watching a five-year-old hold a worm still, squint at it, and whisper "I found it!" — that is exactly what science is supposed to feel like.

🌱 For centuries, Europeans thought earthworms were pests. Then Charles Darwin spent 40 years watching them, weighing their castings — and yes, actually listening to them. He played piano near their pots. He had his son blast a bassoon. He shouted at them. The worms ignored all of it — until someone put their pot ON TOP of the piano. Turns out earthworms don't hear sound. They feel vibration. Darwin figured that out in his living room.

That one scientist changed everything. Aristotle had known worms mattered. Cleopatra had protected them by law. Darwin convinced the rest of the world.

Today, so did we.
