Incredible Aurora Photos by Daniel Forster Light Up the Night
This week, North America was audience to an unusually large and powerful solar storm, which created dazzling Northern Lights across larges swaths of the continent.
Indeed, from Canada down to Arizona and even Florida, the aurora borealis was visible.
Photographer Daniel Forster was ready, and captured some truly stunning views of the colorful sky over Colorado’s Garden of the Gods.
The photos below showcase the extent of the vibrant aurora, which look astounding behind the craggy rock formation outside of Colorado Springs.

But what can you actually DO about the proclaimed ‘AI bubble’? Billionaires know an alternative…
Sure, if you held your stocks since the dotcom bubble, you would’ve been up—eventually. But three years after the dot-com bust the S&P 500 was still far down from its peak. So, how else can you invest when almost every market is tied to stocks?
Lo and behold, billionaires have an alternative way to diversify: allocate to a physical asset class that outpaced the S&P by 15% from 1995 to 2025, with almost no correlation to equities. It’s part of a massive global market, long leveraged by the ultra-wealthy (Bezos, Gates, Rockefellers etc).

Meet the Jellyfish That Never Dies
The Jellyfish That Rewinds Its Life
Nature hides strange wonders, but few are as jaw dropping as a jellyfish that refuses to grow old.
Turritopsis dohrnii begins life like any ordinary jellyfish, drifting and pulsing through the sea.
When it faces stress or the natural decline of age, it performs a biological magic trick.
Instead of dying, it reverts its cells and transforms back into its youthful polyp stage. It literally starts over.
The Very Last U.S. Penny Was Minted This Week
A penny for your thoughts on this one…
The U.S. penny, long seen as a virtually-valueless coin, has finally ceased production at the U.S. Mint in Philadelphia.
Indeed, the very last new penny was minted on Wednesday, bringing a long end to the copper-plated coin.
The Abraham Lincoln penny that we know so well has been in circulation since 1909, though the United States has had a once cent coin as far back as 1787.
Over the years, as prices have risen, the usefulness of a penny has come into question, especially as it costs over 2¢ to make a single 1¢ coin.
With the retirement of the penny, consumers will still be able to use them as currency, but they will no longer be produced.
With billions of them still in circulation, we don’t see the penny becoming a collector’s item for quite some time, however.
Toyota’s Crab-Like Wheelchair That Walks
Unveiled at the Japan Mobility Show, the company’s new autonomous wheelchair concept trades traditional wheels for four folding, articulated legs.
Entitled ‘Walk Me’, the concept is distinctly elegant but also alien-like.
The legs extend and contract like a robotic animal, letting the chair climb stairs, handle uneven ground, and even lower itself gently to floor level.
The effect is part gentle companion, part sci-fi exoskeleton. Instead of treating obstacles as barriers, the chair simply changes shape, adapting its stance to the environment. The way the legs articulate and fold to ‘sit’ look particularly creature-like.
Sagrada Família Becomes Tallest Church in the World as it Nears Completion
A whopping 143 years after it started construction, the massive, ornate Sagrada Família cathedral in Barcelona is nearing completion.
New video showcases the enormous cathedral’s lower cross being placed by crane, officially making it the tallest church in the world.

When the exterior is completed in 2026, it will reach an impressive 172 meters (564.3 feet) into the air, towering over much of Barcelona.

The Catalan architect Antoni Gaudí is the mastermind behind the design, which is unlike anything else in the world of architecture, and combines Gothic and curvilinear Art Nouveau forms.

Nature Fact of the Day

The black sapote, also called the chocolate pudding fruit, ripens into a dark, custard-like flesh with a flavor uncannily close to rich chocolate. It even has the silky texture of mousse.
People bake with it, spread it on toast, and use it as a natural dessert base. Yet most of the world has never heard of it.
