The zebra jumping spider known as Nefertiti makes its rounds inside a habitat on the International Space Station during a student-designed experiment.

The spider who became the star of an Egyptian teenager's outer-space experiment has settled into the Smithsonian Institution's National Museum of Natural History after returning from a three-month stint aboard the International Space Station.

The zebra jumping spider, known as Nefertiti, was sent into orbit aboard a Japanese cargo ship in July as part of the YouTube Space Lab project. Amr Mohamed, an 18-year-old student from Alexandria, Egypt, proposed the trip as part of an experiment to see whether the "spidernaut" could adapt to zero gravity and pounce on its prey the way it would on Earth. NASA astronaut Sunita Williams kept watch on the spider and confirmed that it could adjust its jumping trajectory to catch small insects.

"I think the spider's absolutely adapted to space," PhysicsCentral quoted Williams as saying in September.

After its stint in orbit, Nefertiti was brought back to Earth aboard SpaceX's Dragon capsule and returned to BioServe Space Technologies, a center at the University of Colorado that facilitates life-science experiments on the space station. The natural history museum's director, Kirk Johnson, personally escorted the spider from Colorado to the museum's Insect Zoo in Washington.

"The Insect Zoo is one of our most popular exhibitions, and we are thrilled that having such a great educational space also gives us the opportunity to host a critter as special as this space-traveling spider," Johnson said in a news release issued today. "And don't think it’s lost on me that the common name for this spider is the 'Jumping Johnson'; we’re practically family already!"

Nefertiti's life span is estimated to be about six months. It will spend its remaining time on display inside the same habitat it occupied in space, which is now set up adjacent to the Insect Zoo's Live Butterfly Pavilion. Although the Smithsonian says "Neffi" is the first jumping spider to return from orbit and successfully readjust to life on Earth, it's not the first spidernaut. Spiders have been spinning their way into Earth orbit for decades. And don't get me started about the Spiders From Mars....

Researchers have engineered silkworms to produce silk with the strength and elasticity of spider silk. The breakthrough avoids the task of spider farming.

Researchers have hacked the silkworm genome to spin fibers containing spider-silk proteins, a breakthrough that could lead to a long-sought biomaterial for a range of applications such as sutures, artificial ligaments and even bulletproof vests.

To prove the engineered silkworms were actually producing the synthetic silk, the researchers tagged some with green fluorescent protein, creating green-glowing silk.

As spooky as this may seem, it is a big step on a path to manufacturing silk with spider-silk-like qualities without having to venture into the even scarier proposition of spider farming.

Indeed, spider farming isn't even a viable option given spiders' penchant for "territorialism and cannibalism," note the researchers in this week's issue of Proceedings of the National Academy of Sciences.

The team, led by Donald Jarvis at the University of Wyoming, isn't the first to incorporate spider silk proteins into silkworms, but is the first to report stable integration of spider proteins in the composite silk fibers.

"On average, the composite fibers produced by our transgenic silkworm lines were significantly tougher than those produced by parental animals and as tough as native dragline spider silk fiber," the team concludes.

The caveat is that "very few of the transgenic animals produced anything nearly so tough. And there was little consistency among the different transgenic lines," John Timmer notes in Ars Technica.

Improved results could come with further transgenic constructs or knocking out some of the silkworm's native genes, he says, but adds improving the inconsistent quality of the silk is "a tough hurdle to clear."
