Visitors to London Zoo last autumn stood enthralled, watching the family dynamics of the critically endangered Sumatran tiger playing out before them. The two newborn cubs, instinctively mischievous, repeatedly pounced and climbed up their 280-pound father, claws unsheathed. Crowds admired this tiger, built for predatory power, turning his obvious annoyance into gentle reprimands. The scene is reminiscent of Aslan the lion, whom C. S. Lewis used to capture some of the attributes of God—tender but also powerful and “not a tame lion.”
Today, these majestic cats are the focus of World Wildlife Day, along with the other big cats that are under threat on our watch—no, because of our watch. Habitat loss, conflict with people, and poaching are just some of the reasons for their drastic declines. There has been a 95 percent drop in tiger numbers over the last hundred years and a 40 percent drop in African lions over just 20 years.
It’s obvious that our own planet is friendly to life, but what about the rest of the universe? Is the rest of space too cold and dark – or hot – to allow life to develop? Was the development of life on earth a hugely improbably event, or pretty much a forgone conclusion? The Nobel Prize-winning biochemist Christian de Duve spent the last few years of his career investigating this question, and came up with a surprising answer. In this post I’ll share five of the characteristics of life that he studied. Continue reading →
Children are delighted by living things that most adults think are icky or mundane. Last spring my daughter Lucy, now age 6, found a large earthworm and named it Cinderella. She played with it for hours. Not a week later my son Josiah, 4, caught a big brown toad in our backyard and squealed repeatedly, “He’s adorable!” (Not everyone would pick that adjective, but I agreed.) They fixate on the fish tank at the dentist’s office or our family’s ant farm, taking in every detail and pestering me with a steady stream of questions.
Some of the questions they ask are profound. We were almost to school the other day when Lucy asked, “Is there any number bigger than infinity?” and then, “Is God bigger than infinity?” I paused, breathless with parental joy, before I responded. Continue reading →
I am an ex-cell biologist. Whilst I was a PhD student, it felt like cells were involved in every aspect of my life. I would grow cells, study cells, read about cells, spin them in centrifuges, look at them down a microscope, and visit them at 2am to take timepoints for particularly gruelling experiments. When I spoke to my relatives, the question ‘How are you?’ was often followed by: ‘How are your cells behaving?’. Continue reading →
As they were going out, they met a man from Cyrene, named Simon, and they forced him to carry the cross. They came to a place called Golgotha (which means ‘the place of the skull’). There they offered Jesus wine to drink, mixed with gall; but after tasting it, he refused to drink it. When they had crucified him, they divided up his clothes by casting lots. And sitting down, they kept watch over him there. Above his head they placed the written charge against him:
this is jesus, the king of the jews.
Some of the most beautiful things in the world have an ugly side. I was recently Continue reading →
Certainly the body isn’t one part but many. If the foot says, ‘I’m not part of the body because I’m not a hand’, does that mean it’s not part of the body? If the ear says, ‘I’m not part of the body because I’m not an eye’, does that mean it’s not part of the body? If the whole body were an eye, what would happen to the hearing? And if the whole body were an ear, what would happen to the sense of smell? But as it is, God has placed each one of the parts in the body just like he wanted. If all were one and the same body part, what would happen to the body? But as it is, there are many parts but one body. So the eye can’t say to the hand, ‘I don’t need you’, or in turn, the head can’t say to the feet, ‘I don’t need you’. Instead, the parts of the body that people think are the weakest are the most necessary.
(1 Corinthians 12.14 –22, CEB)
In this passage, St Paul is referring to parts of the body that we can see, but equally important are the millions of molecular machines and processes that we cannot see but nevertheless sustain our every Continue reading →
