I struggle to keep my footing on a narrow ridge of earth snaking between flooded fields of rice. The stalks, almost ready to harvest, ripple in the breeze, giving the valley the appearance of a shimmering green sea. In the distance, steep limestone hills rise from the ground, perhaps 400 feet tall, the remains of […]
Wonders of the microscopic world
I have a background in microbiology – for my PhD I studied the corkscrew-shaped bacterium Campylobacter jejuni – so when I was recently asked to interview Rutgers University microbiologist Paul Falkowski for the brilliant website Five Books, I jumped at the chance to hear about his recommended reads. First up was what Falkowski describes as […]

Here’s a gorgeous video featuring a mechanical model of the solar system, attributed to the famed Greek inventor Archimedes and now reconstructed by the London-based mechanician Michael Wright. This globe, made from copper and brass (although the original would have been bronze) displays the movements of the Sun, Moon and planets as they travel through […]

Each spore consists of a spherical body with four spindly legs. In humid conditions these legs wrap […]

Despite my growing bump I was on my knees scrubbing skirting boards and climbing ladders to roller paint the ceiling. With my second pregnancy too, I couldn’t stop tidying […]
