Earth’s oceans are having a rough go of it these days. On top of being the repository for millions of tons of plastic waste, global warming is affecting the oceans and upsetting marine ecosystems in potentially irreversible ways.

“Just how old do you think my dog is in dog years?” is a question I hear on a regular basis. People love to anthropomorphize pets, attributing human characteristics to them. And most of us want to extend our animal friends’ healthy lives for as long as possible.

The whale shark is the largest fish in the world, but much of its life cycle remains shrouded in mystery. These gentle giants gather in just a handful of places around the globe – something which has long baffled scientists – but our new research has started to explain why. Better understanding of whale shark movements could help prevent further population loss in a species that has already experienced a 63% population decline over the past 75 years.

There’s a tree that once covered the whole of Australia, then dwindled to a dozen examples, and is now spread around the world. We call it the Wollemi pine (Wollemia nobilis), but you could call it the dinosaur tree.

For their first 100 million years on planet Earth, our mammal ancestors relied on the cover of darkness to escape their dinosaur predators and competitors. Only after the meteor-induced mass extinction of dinosaurs66 million years ago could these nocturnal mammals explore the many wondrous opportunities available in the light of day.

When it comes to bees, it seems that nothing really does matter. As shown in a paper published today, our research demonstrates that the honeybee can understand the quantitative value of nothing, and place zero in the correct position along a line of sequential numbers.

Marine zooplankton are tiny animals, roughly the size of insects you might see on a summer day, that drift with ocean currents. Many of them are lovely, but except for scientists who study them, few people are aware that they are among the most numerous – and important – animals on Earth.

Starting about 7,000 years ago, and extending over the next two millennia, recent studies suggest, the genetic diversity of men—specifically, the diversity of their Y chromosomes—collapsed. The collapse was so extreme it was as if there were only one man left to mate for every 17 women.

Declines in bee populations around the world have been widely reported over the past several decades. Much attention has focused on honey bees, which commercial beekeepers transport all over the United States to pollinate crops.

Unfortunately, both mammoth and most of the mammoth steppe ecosystem today have long but disappeared. But a group of geneticists from Harvard are hoping to change this by cloning living elephant cells that contain a small component of synthesized mammoth DNA

In a simulated small intestinal microbiome, a cocktail of viruses successfully targeted and killed E. coli without harming its bacterial neighbors.

Earth’s crust is made up of fractured slabs of rock, like a broken shell on an egg. These plates move around at speeds of about 5cm per year – and eventually this movement brings all the continents together and form what is known as a supercontinent. The last supercontinent on Earth was Pangaea, which existed between 300-180m years ago.

Genetic analysis reveals new evidence to explain how the hogfish uses its skin to “see.”The hogfish is a pointy-snouted reef fish that can go from pearly white to mottled brown to reddish in a matter of milliseconds as it adjusts to shifting conditions on the ocean floor.

If you go down to the shore today, you’re sure of a big surprise. Many will have witnessed the presence of a starfish or two when visiting the seashore or a public aquarium. Starfish come in an exciting range of colours and sizes, but have you ever given a thought to how this multi-armed wonder manages to exist in our oceans when it’s so unlike the other animals we know?

What do birds and aerospace engineers have in common? Both have invented incredibly dark, “super-black” surfaces that absorb almost every last bit of light that strikes them.

Years ago, we believed that we weren’t animals and that animals were here solely for our use. Indeed, a cow was just a walking burger, steak of Sunday roast, keeping itself fresh and tasty ready for when we were hungry.

Humans have built high-rises since ancient Roman times, but it wasn’t until the 20th century that they became the default work space for a significant slice of the world’s workers. While these buildings are certainly efficient, they can cause real health issues.
