Send
For most scuba divers, few places underwater match the visual thrill of a kaleidoscopic coral reef teeming with colourful fish. For Jeff Milisen, a marine biologist and photographer in Kona, Hawaii, there is no better place to dive than an open stretch of deep ocean.
Chennai:
At night. âThereâs a whole lot of nothing,â he said. âThereâs no bottom, no walls, just this space that goes to infinity. And one thing you realise is there are a lot of sea monsters there, but theyâre tiny.â
Of course, there are big monsters, too, like sharks. But the creatures Milisen is referring to are part of a daily movement of larval fish and invertebrates, which rise from the depths to the surface each evening as part of one of the largest migrations of organisms on the planet. The emerging hobby of taking pictures of them is known as blackwater photography. ....

Tropical rainforests today are biodiversity hotspots and play an important role in the world s climate systems. A new study published today in
Science sheds light on the origins of modern rainforests and may help scientists understand how rainforests will respond to a rapidly changing climate in the future.

Dom Pedro aquamarine was cut from a 100-pound crystal that was mined in the late 1980s. It weighs around 4.6 pounds, making it one of the largest aquamarine gemstones in the world. (Donald E. Hurlbert, Smithsonian)
For those who study what happens when magma and crust collide, igneous rocks like pegmatites are a welcome sight. But in addition to holding clues about Earth’s mineral and geologic processes, pegmatites deposits are known for containing diverse and richly colored mineral crystals that can be cut into spectacular gems. One of the largest if not best example is the Dom Pedro Aquamarine. ....
