It’s our January issue and we wanted to kick off the year with a big bang, so we asked one of our favourite writers, Marcus Chown, to give us a concise guide to nothing less than the biggest mysteries in the Universe. No one writes quite like Marcus, so grab yourself a hot drink, curl up in a corner away from wintry chills and turn to p46. Speaking of the weather, researchers at Stanford University have discovered that the human body has its own set of seasons. At particular times, molecules and microbes inside us fluctuate to meet to the changing environment around us. It’s a fascinating piece of work that demonstrates the kinds of discoveries we might make with a multiomics approach to medicine: that is, being able to study…

Buzz off! WASHINGTON STATE, US In October, the US’s first confirmed nest of Asian giant hornets (Vespa mandarinia) was destroyed by scientists in Washington state. The invasive insects are also known as ‘murder hornets’ as they are voracious predators of honeybees, which are important pollinators of crops. The team attached tiny tracker devices to some worker hornets, which led them back to the nest in a tree cavity. The vacuum device seen here was used to extract the insects, before carbon dioxide was pumped into the tree to anaesthetise any stragglers. The scientists had to wear protective suits, as the hornets can sting multiple times and are able to spray venom. While US bees cannot defend themselves against the hornets, Japanese honeybees, having evolved alongside the predators, have a trick to ward off attacks:…

Plastic-henge After reading your article about Prof Trevor Cox’s work at Stonehenge (October, p22) I found myself asking, “what’s missing from this experiment?” Many years ago, I qualified as a stonemason. We learned how to tell if a stone had any flaws: you take your chisel and bang it against the stone: the sound resonance will either ring true and clear, like flicking a crystal glass, or give a dull thud if the stone is flawed. So, how can any sound reflected from a piece of printed plastic give a true indication of the actual sound, especially from the harder bluestones from the Preseli Hills? I’m sure Cox thought of this, but it wasn’t mentioned in the article. I’d be very interested to know what he thinks. Gary Sansom Our experiments were not concerned…
