The ins and outs of how we colour our food
Nestle’s new television adverts for Smarties are a cross between grown-up Teletubbies in head-to-toe lycra jumpsuits and the parable of the prodigal son. You’ve probably caught a glimpse of their idyllic, pastoral scene being abruptly disrupted by the appearance of Blue Smartie on the ridgeline. His former friends flee to the safety of their tubular home, dispatching Yellow to get rid of the unwelcome intruder. All is well though, because [...]

Where do we come from? Paul Rodgers charts some of the latest work exploring the movement and development of humans based on DNA and the full mitochondrial genome
Where do we come from? It’s an abiding question, and one that has been only partially answered by science. While little doubt remains that our species evolved in East Africa, details of its spread around the world are still obscure. And the further back we peer, the harder it is to get a clear picture.
What evidence we have falls into three categories: physical remains, such as stone tools and [...]

Having discovered chaos, Lorenz explored deeper and found that a form of unpredictable order could spontaneously arise from it. Paul Rodgers on a remarkable scientist
Could the flap of a butterfly's wings in Brazil set off a tornado in Texas, asked mathematician and meteorologist Edward Lorenz in a 1972 paper? It was a small question, with an appropriately huge answer.
The weather, Professor Lorenz demonstrated, is extremely sensitive to minute changes in initial conditions. Forecasting a month in advance is all but impossible. Though Lorenz shied away from blaming storms around Houston on the [...]

The very real dangers posed to our honey bees
"If the bee disappeared off the surface of the globe then Man would have only four years of life left. No more bees, no more pollination, no more plants, no more animals, no more life.” This quote, often attributed to Albert Einstein though there is no record of him saying anything like it, has been doing the rounds in apian circles since the nineties. If the calculation is true, notwithstanding [...]
Embryology and Catholicism

Why is it that the Catholic Church is so vehemently opposed to something that has so many possibilities?
In the Iliad, Homer described Chimera as “lion-fronted and snake behind, a goat in the middle, and snorting out the breath of the terrible flame of bright fire”. She was a monster, good only as a target for Bellerophon’s lead-tipped spear. To listen to the spiritual descendants of the Greek hero, you might think modern-day chimera were equally foul. The Catholic bishops leading the pro-life brigade don’t just want to [...]

Paul Rodgers explains why he thinks it's time for a very famous British institution to close
For a science-mad kid growing up in the West Midlands during the 1960s, the centre of the universe lay in a muddy field 20 miles south of Manchester. While the Americans had Cape Kennedy, we had Jodrell Bank. And if Britain couldn't quite land a man on the Moon, we stood a much better chance of being the first to hear from the aliens every nine-year-old just knows are already [...]
