Happy Shark Week, science fans! To mark the occasion, we had a flurry of fishy features this week, including a first look at the secret lives of whale sharks, as seen from cameras on the animals' fins, and the discovery of a "demon cavefish" beneath a World War II chemical weapons facility in Alabama.
This week, we also saw the first drone footage of the birth of a humpback whale.
Meanwhile, off the coast of Spain, the orcas are at it again, sinking yet another ship along the Iberian coast. And speaking of boats, as cargo ships continue to stall near the Strait of Hormuz, scientists have warned of an imminent biological "superspreader" event once the key shipping route reopens.

While the Northern Hemisphere battled heat waves and wildfires, Antarctica just experienced the lowest temperature recorded on Earth in over a decade. High-altitude research station Concordia, located in the icy continent's interior, logged a low of minus 119.4 degrees Fahrenheit (minus 84.1 degrees Celsius) on July 18, just shy of the coldest temperature ever recorded at the station.
"Even here, where extreme cold is expected, temperatures below minus 84 C are remarkable and highlight how variable Antarctic weather can still be," Gabriele Carugati, the station leader at Concordia for Italy's National Antarctic Research Program, told Live Science from the station.

Why do cats have 'leg whiskers'?
Cats have a tuft of four to six whiskers on the back of each front leg, each about 0.8 to 1.2 inches (2 to 3 centimeters) long. (Image credit: sellyhutapea Getty Images)Cats are known for having whiskers on their faces. But if you look closely, you'll see they also have them on their legs. So what are these leg whiskers for? And how do they differ from the ones on their face?

A significant portion of the Amazon rainforest remains unexplored, and even from above, it's almost impossible to see through the trees' thick canopies to find out what lies beneath. However, thanks to modern laser scanning technology, scientists have peered through this wall of leaves — and what they've found may offer new insight into lost human civilizations.
A new lidar survey has revealed hundreds of earthworks made by the Aquiry people, who arose 2,500 years ago in Brazil. So what can these structures teach us about this mysterious lost civilization?

Inflammation may trigger persistent 'out-of-body' experiences, emerging research hints

We're increasingly learning about the role of chronic inflammation in a range of diseases, from autoimmune conditions like rheumatoid arthritis to neurodegenerative diseases like Alzheimer's. However, scientists may have now added a new surprising side effect to this immune response: "out-of-body" experiences.
It's been known for a while that trauma can trigger altered states of consciousness, but exactly what was causing this psychiatric response was unclear. Now, scientists have found that stress triggered by trauma may dial up chronic inflammation, which could, in turn, trigger these dissociative disorders.

Chinese rocket hit by rare midair lightning strike moments after launch as onlookers gasp in horror

It's like something from a movie: Seconds after China's Long March 3B rocket launched on July 23, the spacecraft was struck by lightning. Hundreds of spectators watched in shock as at least 100 million volts of electricity hit the craft and surged around its fuselage and through its exhaust plume, before shooting down to Earth.
Despite the strike, the uncrewed rocket safely reached space and successfully deployed its payload into orbit.
