Various water-striding insects use small body sizes, long legs, and fine hairs on their feet to skate on the surfaces of ponds and streams. But life on the open ocean presents tougher challenges than landlocked waterways. Waves, fishes, salt, and birds should spell disaster for such small striders.

A new study published in the journal Gondwana Research has identified a rather out-of-place bone from a theropod dinosaur called an elaphrosaur that apparently didn’t eat meat.¹ In fact, it was toothless.

A recent study, published in Frontiers in Marine Science, reports on the recurring problem of humpback whales colliding with large estuary-trafficking ships.¹

A new study published in the Proceedings of the National Academy of Sciences has again tried to explain a global erosional surface known as the Great Unconformity.¹ This boundary surface marks a major gap in the rock record between Precambrian rocks below and younger sedimentary rocks above.

A new study published in Nature has found that tectonic plates may change directions rapidly, or “wobble,” several months before a massive quake is released.¹ Scientists are not sure why, but it may lead to a future breakthrough in earthquake predictions.
