Astronomers used the powerful ALMA telescope to discover that in other parts of the Milky Way Galaxy (seen here) there is potentially a large population of young planets -- similar in mass to Neptune or Jupiter -- at wide-orbit that are not detectable by other current planet searching techniques.

Thyalacoleo carnifex, the 'marsupial lion' of Pleistocene Australia, was an adept hunter that got around with the help of a strong tail, according to a new study. These insights come after newly discovered remains, including one nearly complete fossil specimen, allowed these researchers to reconstruct this animal's entire skeleton for the first time.

Why did the first big, complex organisms spring to life in deep, dark oceans where food was scarce? A new study finds great depths provided a stable, life-sustaining refuge from wild temperature swings in the shallows.

A team of astronomers has conducted ALMA's first large-scale, high-resolution survey of protoplanetary disks, the belts of dust and gas around young stars.

Small imperfections in a wine glass or tiny creases in a contact lens can be tricky to make out, even in good light. In almost total darkness, images of such transparent features or objects are nearly impossible to decipher. But now, engineers have developed a technique that can reveal these "invisible" objects, in the dark.

A research team has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Move over, trap-jaw ants and mantis shrimp: There's a faster appendage in town. According to a new study, the Dracula ant, Mystrium camillae, can snap its mandibles at speeds of up to 90 meters per second (more than 200 mph), making it the fastest animal movement on record.

NOAA's annual report card on the Arctic, released today, shows that the Arctic region experienced the second-warmest air temperatures ever recorded; the second-lowest overall sea-ice coverage; lowest recorded winter ice in the Bering Sea; and earlier plankton blooms due to early melting of sea ice in the Bering Sea.

The effects of a supernova -- and possibly more than one -- on large ocean life like school-bus-sized Megalodon 2.6 million years ago are detailed in a new article.

Our future on Earth may also be our past. Researchers show that humans are reversing a long-term cooling trend tracing back at least 50 million years. And it's taken just two centuries.
