AQA - Which came first, the chicken or the egg?

In this episode of Any Question Answered, Ross Exton answers two questions from visitors to the science centre, At-Bristol:

‘When lightning strikes the sea, why don’t all the fish die?’
‘Which came first, the chicken or the egg?’

If you have any questions you want the answer to, tweet either Ross or At-Bristol with the hashtage #abAQA; one will be picked one to include in the next AQA to feature alongside the questions from visitors.

Beyond their pretty remarkable ability to “think” and problem-solve, slime molds are just plain beautiful.

John Bonner, a professor emeritus at Princeton, has been studying them for seventy years. He’s been fascinated by the ability of this “bag of amoebae encased in a thin slime sheath” to operate like a simple brain, despite its biological simplicity. He’s used the gooey little guys to further the study of evolution and development for over half a century, and some of the images he’s collected are stunning.

The GIFs above are from this collection of half-century-old film clips captured by a young Bonner, showing the life cycle of a slime mold. Lastly, you absolutely do not want to miss this gorgeous new collection of close-up slime mold photos SciAm’s Alex Wild.

Old and new, these little creatures are as beautiful in form as they are amazing in biology.

infinity-imagined:

The DNA Replication Complex, an assembly of proteins that synthesizes new DNA before cell division. It consists of Helicase, Primase, Single-strand binding proteins, and DNA polymerase III. Because DNA strands can only be copied in one direction, the complex must pull out loops of one strand and replicate it in fragments. At this moment there are hundreds of trillions of these molecular machines in constant activity within your body.

Elon Musk Wants to Build 80,000-Person Mars Colony | Wired Science | Wired.com:

wildcat2030:

Elon Musk doesn’t just want to send a person to Mars — he wants to send 80,000. According to Space.com, the billionaire founder and CEO of the private spaceflight company SpaceX spilled details about his hopes for a future Mars colony during a talk at the Royal Aeronautical Society in London on Nov. 16. Earlier this year, SpaceX became the first private U.S. company to deliver cargo to the International Space Station. Musk has never been shy about his ambitions to take human colonists to another planet, mentioning in the past that he wants to provide flights to Mars for about $500,000 a person. But now he’s talking about building a small-city-sized settlement on the Red Planet, starting with a 10-person crew in the coming decades to begin establishing and building infrastructure. That first flight would be expensive and risky but “once there are regular Mars flights, you can get the cost down to half a million dollars for someone to move to Mars,” Musk told Space.com. ”Then I think there are enough people who would buy that to have it be a reasonable business case.” Musk added that he sees the future 80,000-person colony as a public-private enterprise costing roughly $36 billion. Science-fiction inspired plans are one thing. Musk still has many challenges ahead of him before such a scheme could become reality, including figuring out exactly how to deal with radiation on the way to Mars, how to land humans on the planet’s surface, and how to keep them alive once there. Wired Magazine Editor Chris Anderson interviewed Musk in the November issue, where he outlines a few ways that could help us get there:
