Bugula neritina is a rather inconspicuous marine organism. It looks like purplish seaweed, but it’s actually a branching colony of individual, tentacled zooids (the technical term for individuals in a colonial invertebrate) that resemble badminton shuttlecocks. It’s abundant, invasive and widely viewed as a pest as it accumulates on ships, dock sides, buoys and intake valves.
It might also contain a cure to some ...read more

Smoking: It’s bad for you. Take the smoke out of smoking, though, and you might be on to something.
That, at least, is the thought process behind newly-emerging smokeless forms of nicotine, the most prominent right now being e-cigarettes. A vape pen just doesn’t deliver the same sweet rush of nicotine and the satisfying “throat hit” smokers crave, though, leaving tobacco companies searchi ...read more
Sea urchins living in the Mediterranean have a new enemy: the bearded fireworm. This toothless but determined predator has found a way to devour sea urchins, despite their spines and stony shells. And the worms’ appetite for urchins might remake entire ocean ecosystems.
The bearded fireworm, Hermodice carunculata, grows up to a foot long and is fuzzy, not in the cute way but in the “DO NOT TOUCH” way. The white tufts that run along the worm’s bod ...read more

Bambi: A classic children’s movie about a happy-go-lucky fawn that ultimately takes a turn for the worse. Unfortunately, real life is no walk in the park for young deer either.
Early in a fawn’s life, its mother will leave for extended periods to forage for food and ensure predators stay at bay, wildlife experts say. But nesting in farm fields can be deadly for fawns, as farmers often don’t see them before it’s far too late.

Hang around any mom with a young child and eventually she’ll break out her baby voice. You know the one — the pitch of her voice goes up, her words are simple and exaggerated. It’s sometimes referred to as motherese, but researchers call it infant-directed speech. Whatever you want to call it, it’s pretty vital to little ones’ development. Says Elise Piazza, a neuroscientist at Princeton University, it “helps babies to segment this hug ...read more
Easter Island, or Rapa Nui, is best known for its giant carved moai. (Credit Terry Hunt)
Thanks to its geography, the southeastern Pacific island of Rapa Nui — also known as Easter Island — has been in the center of a long-running debate about how early people may have sailed back and forth across the planet’s biggest ocean. One theory suggested that, long before Europeans arrived, the island was a meeting point for Polynesians and Native Americans.
Spoiler alert: a new s ...read more
The MOOSE concept. GE.
Imagine an astronaut on board a dying spacecraft in orbit. The vehicle is losing power and there’s no way it will be able to make it safely back through the atmosphere. There’s no evacuation system in place and no other spacecraft ready to send up on a rescue mission. Without a way to get home, without some life boat of sorts, that astronaut is going to die in space…
This was the nightmare scenario General Electric had in mind when it developed a space ...read more

For the first time since September 2011, Kirishima in Japan has started erupting. On the morning of October 11, new ash emissions began from the Shinmoe-dake cone on the large, complex volcano on the north end of Kagoshima Bay. The eruption have been relatively small ash-and-gas plumes that reached less than 1 kilometer (~3,200 feet) over the volcano and spread shards of volcanic glass (aka as ...read more

You have probably heard of solar flares before. These bright eruptions from the Sun’s surface are triggered when knotted magnetic field lines within the Sun suddenly snap and reconnect, accelerating fireballs of plasma outward to distances up to 35 times the diameter of the Earth.
But have you ever heard of nanoflares?

Ask people to name the most famous historical woman of science and their answer will likely be: Madame Marie Curie. Push further and ask what she did, and they might say it was something related to radioactivity. (She actually discovered the radioisotopes radium and polonium.) Some might also know that she was the first woman to win a Nobel Prize. (She actually won two.)
But few will know she was also a major hero ...read more
