Remote monitoring of large swathes of inaccessible ocean from satellites that orbit the Earth some 700 km above our heads is set to revolutionise the way that marine biologists and climate scientists study the ocean. Every year more than a quarter of global CO2 emissions from burning fossil fuels and cement production are taken up […]
When tunas dive down to cold depths their body temperature stays warm but their heart temperature can fall by 15 degrees within minutes. The heart is chilled because it receives blood directly from the gills which mirrors water temperature. This clearly imposes stress upon the heart but it keeps beating, despite the temperature change. In most other animals the heart would stop.
Humans are not infallible. We get sick, we get injured. Humans are a clever bunch though, and since prehistoric times we have used medicine to try and heal our ailments. Medical science has made huge leaps and bounds, providing treatments and vaccinations, surgical procedures, and physical and psychological therapies that have allowed people to survive […]
A recent stranding of a basking shark (Cetorhinus maximus) in north-western Bali is the first confirmed record of this large, filter-feeding shark species in Indonesian waters. The shark was an adult male. It is possible that the Indonesian throughflow – the warm ocean current which moves water from the Pacific to the Indian Ocean – is […]
Green sea turtles may stop basking on beaches around the world within a century due to rising sea temperatures, a new study suggests. Naturalists as early as Darwin observed beach basking in green turtles (Chelonia mydas). It helps the threatened animals regulate their body temperatures and may help their digestion and immune systems. After analysing […]
Mother turtles find their way back to nesting beaches by looking for unique magnetic signatures along the coast, according to a new study published in Current Biology. Loggerhead turtles, for example, leave the beach where they were born as hatchlings and traverse entire ocean basins before returning to nest, at regular intervals, on the same stretch of […]
For 50 years the Natural History Museum in London has run the Wildlife Photographer of the Year competition – harnessing the power of photography to inspire greater understanding of the natural world, challenge perceptions and encourage change to preserve the beauty and diversity of the Earth. They are looking for photos that represent the natural […]

Humpback whales work together whilst foraging on the bottom for food – but how do they co-ordinate their behaviour? The answer might be a “tick-tock” song.
