This tragedy – that claimed the lives of 30 of those on board – launched an inquest probing how the hulking 64-cannon ship met such an shameful end. Since the ship still exists almost in its entirety – held at a dedicated museum near Stockholm – we know that investigation was largely correct in its findings. The Sinking of the Swedish WarshipOn the day itself, Vasa set sail on cal ...read more

For that reason, it is “phenomenally important,” according to Emma Nicholls, Collections Manager of Vertebrate Palaeontology at Oxford University’s Museum of Natural History.What we Know About the MegalosaurusMegalos ...read more
Whether you’re talking about sharks, crocodiles, lions, or even velociraptors, some of the most fearsome traits of these predators involve their rows of sharp, crushing, or jagged teeth.Only vertebrate animals have real teeth, though some invertebrates have hard tooth-like plates they use to eat. One of the earliest creatures with teeth were conodonts, an eel-like creature that first appeared around 500 million years ago. These creatures also have the record for the sharpest teeth, according t ...read more
One of the many unseen forces to which you owe your existence is magnetism. If it weren’t for the magnetic field that surrounds our planet, blocking cosmic radiation and solar wind, Earth would likely have little atmosphere to speak of. Life (at least of the human variety) would be impossible.Changes in the field can also play havoc with satellite communication and electric infrastructure, disrupting the modern world in a big way. Given the importance of this gargantuan bar magnet in our day-t ...read more
