It was first spotted in Houston. But then so many strange phenomena are.

Now it's heading your way, regardless of where you might be keeping safe in these excitable United States.

It might seem to you as if it's had a few drinks. But no amount of offering it your Jack or your Bacardi will keep it from one thing it really wants in its mouth.

Yes, your S4, iPhone 5 or, indeed, anything that smacks of electronica.

Nylanderia fulva is its name. But you, at least as far as scientists are concerned, can call it the "crazy ant."… Read more

It sounds like an old black-and-white monster movie. Crazy, tech-nesting ants invade America! That would make for a great matinee, but it's oh so very real. Tawny crazy ants, known scientifically as Nylanderia fulva, are marching into territories once dominated by fire ants -- and they're not being very good neighbors.

While fire ants have made their sting notorious, tawny crazy ants have a propensity to infiltrate unwelcome places en masse. They're making fire ants look positively polite. The South American native ants are attracted to electronics in particular. Once inside, they create short circuits, says University of Texas research assistant Edward LeBrun.

"When they get electrocuted, they release an alarm pheromone," he says, adding that this attracts more ants and exacerbates the problem.… Read more

Humans have a lot in common with magpies. We gravitate toward shiny things.

It's easy, then, to see why the Glowing Plants project on Kickstarter has more than doubled its goal and still has 38 days to go. It's a fascinating mix of botany, science, and unexpected glowing things.

Some people can boast a green thumb, but very few people can boast a glowing green thumb. For a pledge of $40, Glowing Plants will send you 50 to 100 seeds to let you raise your own glowing plant at home. The project's creators say that this is a one-off opportunity and the seeds will not be available commercially later on.… Read more

If the apparel oft proclaims the man, as Polonius said in "Hamlet," then the camo suit proclaims the robot.

Boston Dynamics is showing off new duds for its Petman humanoid robot platform, and it looks rather badass.

Peman is a walking, squatting, flexing hazmat suit testing machine. It's designed to stand up to chemical warfare agents.

With nothing on, it looks like The Terminator. But when it's wearing this camouflage chemical suit and gas mask, you could mistake it for a real soldier. … Read more

Devices that monitor inner ear activity could eventually be powered by the ear itself, according to research detailed in the current issue of the journal Nature Biotechnology by scientists from MIT, Massachusetts Eye and Ear Infirmary (MEEI), and the Harvard-MIT Division of Health Sciences and Technology (HST).

They say that for decades we have known the inner ear houses its own natural battery, but this is the first demonstration of its ability to power something external without compromising hearing.… Read more

Countless childhood dreams dissolved today upon the news that the calculated half-life of DNA figures out to around 521 years, all but invalidating the chances of a real-life "Jurassic Park."

The DNA fact-finding project involved a team of palaeogeneticists testing 158 leg bones belonging to three species of extinct giant moa birds ranging from 600 to 8,000 years old.

After running a series of comparisons between the age of the various bones and DNA degradation within each specimen, the researchers estimated that DNA's half-life works out to about 521 years after being kept in a swamp with an average temperature of 13.1 Celsius (55 Fahrenheit). Even a more ideal preservation temperature of minus 5 Celsius (23 Fahrenheit) would only result in readable DNA from specimens up to 1.5 million years old, meaning there is no possible way we can see a 65-million-year-old T-Rex waving its tiny arms about in this time frame. … Read more

Imagine being able to navigate our own biological tissue much in the way Google Earth allows us to zoom in on our own backyards. Only instead of mailboxes and fences, you could spot, say, rogue cancer cells.

Researchers out of Leiden University Medical Center in the Netherlands may be making such a future possible by stitching together molecular- and cellular-level images of biological tissues into truly gigantic composite images.

One such landscape -- of a zebrafish embryo -- consists of 26,000 images, is 281 gigapixels, and boasts a resolution of 16 million pixels per inch.

The researchers explain their … Read more

Roughly 20,000 years ago the great ice sheets that buried much of Asia, Europe, and North America stopped their creeping advance. Within a few hundred years sea levels in some places had risen by as much as 10 meters -- more than if the ice sheet that still covers Greenland were to melt today. This freshwater flood filled the North Atlantic and also shut down the ocean currents that conveyed warmer water from equatorial regions northward. The equatorial heat warmed the precincts of Antarctica in the Southern Hemisphere instead, shrinking the fringing sea ice and changing the circumpolar winds. … Read more

There's a lot of ways to visualize your Twitter and Facebook feeds, but no one's ever gone down to the cellular level to do so.

Until now, that is. This morning, San Francisco startup Bloom released its latest iPad app, Biologic, which aims to bring an all-new metaphor to looking at the flow of information coming in from leading social networks.

Last year, Bloom--which was funded by Betaworks, SV Angel, and Flickr co-founder Stewart Butterfield, and which was founded by veterans of Stamen Design and frogdesign--released its first app, Planetary. That app brought a galactic approach to users' … Read more
