In which John Green explores how Spain went from being a middling European power to one of the most powerful empires on Earth, thanks to their plunder of the New World in the 16th and 17th centuries. Learn how Spain managed to destroy the two biggest pre-Columbian civilizations, mine a mountain made of silver, mishandle their economy, and lose it all by the mid-1700s. Come along for the roller coaster ride with Charles I (he was also Charles V), Philip II, Atahualpa, Moctezuma, Hernán Cortés, and Francisco Pizarro as Spain rises and falls, and takes two empires and China down with them.

Dolphins are among the most unique mammals. Despite the fact that they look like really big fish, they are not! They breathe air, give live birth to their young, nurse their babies with milk, have hair at some point, and are warm-blooded. Did you know that dolphins are actually part of the larger group of animals called whales? Enjoy the full video here:

Glacier ice is weird. It’s solid. Solid things aren’t supposed to flow. But glacier ice flows like a liquid, and it does that without melting! How is this possible? I traveled to Mendenhall Glacier in Juneau, Alaska to find out.

A critical security flaw has emerged in the Anthropic’s Claude Google Chrome Extension, sparking major concerns across the cybersecurity landscape. Uncovered by Oren Yomtov from Koi Security, this vulnerability was exposed through a detailed report sent to The Hacker News. The alarming flaw allowed any website to insert prompts into the Claude assistant without needing the user’s permission through clicks or interactions. By merely visiting a webpage, users could inadvertently activate this exploit, enabling malicious actors to alter the assistant's behavior, effectively bypassing security protocols. ⛔🌐😱

The implications are vast; these silent prompt injections could enable unauthorized actions on an AI assistant, risking user data security significantly. Such vulnerabilities not only pose immediate data threats but also undermine trust in browser extensions, especially those with integrated AI capabilities. 🛡️🔍

Technically, the root of this vulnerability stemmed from inadequate input validation, which, when absent, allows external forces like websites to manipulate extension behavior. Properly validating input data is crucial for security, and its absence made silent injections feasible. 🔨🔧

Upon recognizing this flaw, Anthropic quickly patched the issue, working closely with the security researcher to protect users. This joint effort underscores the importance of cooperative problem-solving in cybersecurity. Developers are urged to continuously validate inputs, test extensively, and regularly audit for security to thwart future vulnerabilities. Users should ensure extensions are updated and periodically review permissions to safeguard against emerging threats. 🔄🔒

Song Lyrics:
Kaylee found a talking frog,
and being a kind little miss,
she picked up the frog, who asked her,
"Would you kindly give me a kiss?"
She kissed the frog on the top of his head,
then jumped back in surprise.
The talking frog turned into a king,
right before her eyes!

The king gave Kaylee the key to his kingdom,
and asked, "Will you marry me?"
Kaylee married the king, and they had lots of kids,
and forever lived happily!

Hooray! (Hooray!) Hooray! (Hooray!) for the letter k!
The one that comes right after the letter j.
I could sing about k all day.
Hooray! (Hooray!) Hooray! (Hooray!) for the letter k!

Kenny was a musical kid,
who played songs on his kazoo.
But when he did, it tickled his nose,
and made him sneeze, "Kerchoo!"
He had a little sister named Kimmy,
who liked to fly her kite.
Kenny helped Kimmy to tie on a string
and told her, "Hold it tight!"

But Kimmy couldn't keep holding on,
and the kite flew way up high.
When it disappeared behind a cloud,
she kissed that kite goodbye!

Hooray! (Hooray!) Hooray! (Hooray!) for the letter k!
The one that comes right after the letter j.
I could sing about k all day.
Hooray! (Hooray!) Hooray! (Hooray!) for the letter k!

So here's to Kaylee, the king, the kiss, and the key,
to Kenny and his kazoo,
to Kimmy's kite that flew out of sight,
and the sneeze that went, "Kerchoo!"

Hooray! (Hooray!) Hooray! (Hooray!) for the letter k!
The one that comes right after the letter j.
I could sing about k all day.
Hooray! (Hooray!) Hooray! (Hooray!) for the letter k!

Hooray! (Hooray!) Hooray! (Hooray!) for the letter k!
The one that comes right after the letter j.
I could sing about k all day.
Hooray! (Hooray!) Hooray! (Hooray!) for the letter k!
