Today, about a third of the world’s population is infected with a strange disease called toxoplasmosis — and most of them never even know it. And while the parasite can multiply in practically any host, it can only reproduce sexually in the intestines of cats. Could this disease be the reason so many people love cats and keep them as pets? Jaap de Roode shares what we know about toxoplasmosis.

The London team were pleased to welcome Patrick McGinnis to Google, to discuss his latest book "The 10% Entrepreneur" and the multiple paths you can follow to invest your cash, time, and expertise in areas you feel passionate about.
Recorded in London, May 2016
Patrick is on Twitter at @pjmcginnis
About the book:
Choosing between the stability of a traditional career and the upside of entrepreneurship? Why not have both? What if there was a way to have the stability of a day job with the excitement of a startup? In The 10% Entrepreneur, Patrick McGinnis shows you how, by investing just 10% of your time and resources, you can become an entrepreneur without losing a steady paycheck. McGinnis details a step-by-step plan that takes you from identifying your first entrepreneurial project to figuring out the smartest way to commit resources to it. A successful 10% Entrepreneur himself, McGinnis explains the multiple paths you can follow to invest your cash, time, and expertise in a start-up including as a founder, angel, adviser, or aficionado. When you put McGinnis s 10% principles into action, you’ll quickly start racking up small wins, then watch as they snowball into your new (and far more entrepreneurial) life.

Can Martian rocks help us combat climate change?
Ninety seven percent of scientists agree that our planet is warming, with negative social, ecological and financial effects. Our exhibit reveals how one solution to our Earthbound global warming problems may lie underground on Mars, where we believe carbon dioxide from the planet’s ancient atmosphere is now stored as rock.
Our free, week-long festival (Monday 4 July - Sunday 10 July) features 22 curated exhibits and a series of inspiring talks and activities for all ages. https://royalsociety.org/events/summe...

Are you above average? Is your child an A (or D) student? Is your employee an introvert or an extrovert? Every day we are measured against the yardstick of averages, judged according to how closely we resemble it or how far we deviate from it.
The assumption that metrics comparing us to an average—like developmental milestones, GPAs, personality assessments, standardized test results, and performance review rankings—reveal something meaningful about our potential is so ingrained in our consciousness that we don’t even question it. That assumption, says Harvard’s Todd Rose, is spectacularly—and scientifically—wrong.
In The End of Average, Rose draws on insights from the new science of the individual to show that no one is average. Not you. Not your kids. Not your employees. This isn’t hollow sloganeering—it’s a mathematical fact with enormous practical consequences.
But while we know people learn and develop in distinctive ways, these unique patterns of behaviors are lost in our schools and businesses which have been designed around the mythical “average person.” This average-size-fits-all model ignores our differences and fails at recognizing talent. It’s time to change it.
Rose offers an alternative—the three principles of individuality—and reveals how to take full advantage of them to gain an edge in school, in our careers, and in life.

Musser's book is "Spooky Action at a Distance: The Phenomenon That Reimagines Space and Time--and What It Means for Black Holes, the Big Bang, and Theories of Everything" (http://goo.gl/iUwrnU).

Transcript - So spooky action at a distance was Einstein’s kind of appellation for the idea of nonlocality. Non-locality is the technical term for it. So the example I often give is two coins. So you can treat some of these particles as having two possible outcomes of a measurement. And you can think about it as heads or tails of a coin. So you create two of them. You give one to your friend. Your friend goes off somewhere and you keep the other. And you both flip the coin and you come up with heads, they come up with heads. You come up with tails, they come up with tails. Heads, tails. It just goes back and forth. And yet they’re the same answer on both sides.
So this non-local connection among these particles or whatever kind of object is bearing that connection seems to violate our intuition from Einstein’s Theory of Relativity. So that theory among other things said that influences in nature are limited by the speed of light. So you can’t have any kind of subspace radio or answerable like they have in science fiction. There has to be a limit to the speed at which influences the signals can propagate. So these particles which can exist on the opposite sides of the universe seem to disobey that principle. But the situation’s kind of subtle and the reason it’s subtle is that the particles are unable to send an ordinary communication. You can’t use them to radio signal or have some kind of telemetry or remote control across that gap. And the reason is quite simple. The reasons are the outcomes of those particle experiments or the flips of the coin are random. So they just come up heads or tails and heads or tails and you can’t decide is it heads or is it tails. So you’ve got no way to manipulate the coin and thereby produce an outcome at the distant location. So you can’t communicate. You can’t send a signal. So on the one hand the phenomena seems to violate relativity theory. But on the other hand it kind of pulls back from the precipice. It doesn’t actually violate it in a practical sense. You can’t send a signal faster than light.
It still however poses kind of a theoretical conundrum. Why are these particles able to coordinate their behavior even though they’re so far apart. So there’s a tension with Einstein’s Theory of Relativity not perhaps an outright observed contradiction of the theory.
The question of why these particles can coordinate, why these coins can land on the same side no matter where they might be is really it could be very perplexing. And Einstein was troubled by it. He thought the particles for instance were basically had a mechanism in them or some kind of like gimmick built into them like a magician would have kind of a trick coin. And he thought the particles were also like trick coins that they were preprogrammed to land on one side or the other. But in the 60s and 70s that particular explanation was ruled out. So the other possibility is that there might be some kind of signal going between them. But that seems to be ruled out because you couldn’t do the experiment kind of in synchrony. You can do it at the same time and yet the coins can still act in a coordinated way. So you’re kind of left with like what’s going on. It’s just a mystery here. There’s almost like a magical magic wand or Obi-Wan sensing the disruption of all Alderaan kind of situation going on here. It’s kind of a magical situation. So the thinking today is that it represents a violation, a kind of undermining of space, the very fabric of space.
That things in the universe seem to be located far apart from one another. They have individual locations and they need to interact by mechanisms that propagate within space. And these particles violate that expectation so it seems to indicate that space itself is somehow not fundamental. It’s not a real or deep feature of reality.
