This is the true story of 14 tiger sharks, six Galapagos sharks, five sandbar sharks, five bluntnose sixgill sharks and a prickly shark, picked to swim in the ocean and have their lives taped to find out what happens when sharks stop being polite and start getting real.

It took 192 lasers and a building big enough to contain three football fields, but physicists have finally produced a pair of nuclear fusion reactions that created more energy than was in the fuel to start with.

The cost of the anti-vaccine backlash
Columnist Michael Hiltzik brings attention to a startling manifestation of the anti-vaccination movement: The return of illnesses like the measles and whooping cough in countries that had previously beaten them to the curb.
Above is a visualization of outbreaks of measles (in red) and whooping cough (green).

What you’re looking at right now are some of the earliest galaxies ever observed by human eyes, dated to just 500 million years after the big bang.
Science reporter Amina Khan has the full story on these crazy astronomical spirals here.
The Last Launch of Space Shuttle Endeavour
Space Shuttle Endeavour has retired from service, and for the moment NASA is reliant on Russian rockets to keep the International Space Station stocked up and operating. NASA is developing a replacement for the Shuttle – the Orion CEV – but for the moment, lets take a look at the Shuttle and remember the many years of sterling service it has given us.

Some incredible photos, and another reminder of the Endeavour’s victory lap around Los Angeles before settling down in the California Science Center.

Greetings from the new Space Race
So long, Russia vs. U.S. galactic rivalry: With NASA hobbled by budget cuts, the pool of nations vying for the top spot beyond the Earth has grown to dozens of countries, punctuated by China’s recent success on the moon.
It was a moment of national pride when images of the six-wheel rover, dubbed Jade Rabbit, were transmitted live back to Earth, showing the redand gold Chinese flag on the moon for the first time.
"Now as Jade Rabbit has made its touchdown on the moon surface," the state-run Xinhua news agency said, "the whole world again marvels at China’s remarkable space capabilities."
Find out who’s looking to challenge Russia and China in the new race to space here.

As confirmed by the British Medical Journal, James Bond is a bit of a booze hound.
The six-sided weather pattern currently sitting atop the planet’s north pole, which contains a gigantic hurricane - has been raging since 1981.
Lisa Nilsson is making bodies. In her latest show, “Connective Tissue,” the artist takes the increasingly common image of an MRI-like cross-section of a human body and recreates it with swirls of tightly wound paper under glass. Most of the images come from the Visible Human project, a research database maintained by the National Library of Medicine, along with some 19th century medical texts — so everything you see here is anatomically accurate, and each body once belonged to a living person.
For your super-freaky-Saturday-science reading pleasure.

This amazing reentry fireworks was observed from the International Space Station on 2 November at 12:04 GMT. We can see European Space Agency’s fourth Automated Transfer Vehicle, Albert Einstein, disintegrating and burning up in the atmosphere over an uninhabited area of the Pacific Ocean, in the most spectacular way, after it left the International Space Station a week earlier with 1.6 tonnes of waste.

Solar flare marathon may continue
Over the last week, 28 solar flares have exploded on the sun, a quick turn of events from the star, which has been relatively quiet during this period of the sun’s activity cycle.
But there’s little cause for concern, as reporter Deborah Netburn assures:
The good news is that none of the rapid-fire solar flares of the last week have had much effect on life on Earth. Our atmosphere protects us from the sun’s occasional powerful bursts of light and radiation, but solar flares do occasionally interact with our communications systems. The radiation can mess with an upper layer in our atmosphere called the ionosphere and cause radio signals to act funky.
But that doesn’t stop the flares from looking pretty awesome, as you can see above.
As ridiculous as it seems, the U.S. military wants an Iron Man
The metal suit the Pentagon wants would be all but impervious to bullets and shrapnel, and be able to continuously download and display live video feeds from overhead drones. Relying on tiny motors, the exoskeleton would enable a soldier to run and jump without strain while carrying 100 or more pounds.
Happy birthday to the Internet!
You know, that thing that brings us cats and stuff. Forty-four years ago today, a message moved between two computers connected through a network designed to enable the sharing of information between various government funded science projects.
Columnist Michael Hilzik looks back at the web’s infancy, including a forward-looking 1968 paper titled “The Computer as a Communication Device,” co-written by Robert W. Taylor, one of the lead officers at the Defense Department’s Advanced Research Projects Agency.
"In a few years," the paper began, "men will be able to communicate more effectively through a machine than face to face."
Communicating online, he concluded, “will be as natural an extension of individual work as face-to-face communication is now.”
