Can the Los Angeles River be Restored?
The LA River where it meets the Pacific Ocean in Long Beach, California. This is the entry point for migrating steelhead salmon that would hope to return to their spawning grounds in the mountains above Los Angeles. This marks the start of a nearly 40 mile journey upstream, though barriers above prevent a successful migration.

A Rare Glimpse of Disappearing Snowy Owls
This is the ultimate test to compare iPhone camera with my DSLR. It's amazing how well this came out, but still some limitations balancing the shadows of the bush on the rocks with the highlights on the mountain. I even tried to adjust this one a bit afterward, but the contrast range just wasn't there, even considering that I was shooting in RAW mode.

The Stegosaurus Was An Ancient Relic To The T. Rex

By: Joanie Faletto

These two popular dinosaurs never crossed paths.

August 01, 2019

Humans and the Tyrannosaurus rex are closer on the world's timeline than the T. rex and Stegosaurus. Weird, right?

Why It Matters

It's a common error to lump together all non-avian dinosaurs into a single time period. The truth is, dinosaurs roamed the Earth for a long time, and they all most certainly did not exist together. For example, the Stegosaurus roamed the Earth during the late Jurassic period, between 156 and 144 million years ago. On the other hand, the Tyrannosaurus rex lived during the late Cretaceous period, about 67–65 million years ago. The T. rex actually existed closer in history to humans than to the Stegosaurus. Yes, to the T.rex, the Stegosaurus was ancient.

Why It's Relevant

Relative to how long the dinosaurs roamed the Earth, we humans have been around for a blip in time. It can be tempting to think of all non-avian dinosaurs as a single group living at a single point in time, but in reality, that couldn't be further from the truth. When it comes to dinosaurs, most of us have a lot to learn.

Supertrees That Suck Up More Carbon Could Be Forest Climate Fix

Forestation and tree growth are perhaps the most powerful tool for reducing levels of the greenhouse gas carbon dioxide (CO2) in Earth’s atmosphere and tackling climate change. Now genetically modified (GM) ‘supertrees’ that grow faster and rapidly take up CO2 could be used to address the climate crisis.
