Cats get seasonal allergies to pollen and grass, and some have year-round allergies to fleas and dust mites. Sandy Willis, a veterinary internist who advises the American Veterinary Medical Association, says that when cats interact with an allergen, their body sends immunoglobulin E antibodies to link with it, triggering the release of histamine and other chemicals that cause itchy eyes, runny noses, sneezing, hives and rashes.
The Netflix app has been available on Apple’s iOS and Windows Phone 7 since last year. When it finally came out for Android in May, some users found, to their great frustration, that it didn’t work on their phones--not even their fancy new 4G phones like the HTC Thunderbolt.
These ten awe-inspiring science projects range from the world's largest undersea observatory to the "ultimate microscope" to a Jupiter orbiter on a suicide mission--but they're all massive, often in both size and scope
To improve our view of a vast and complex universe, scientists are creating increasingly ambitious new tools. The work is not easy. Truly big science requires decades of expensive commitment from multiple nations. But the instruments that result are nearly as awe-inspiring as the new worlds they help us discover. Check out our ranking of the 10 most epic.

When officials in Santa Coloma de Gramenet, Spain, suggested placing solar panels in the town’s cemetery, they were met with significant skepticism. But after three years of public outreach, the city council prevailed and the town mounted 462 solar panels on top of a quarter-acre of mausoleums.

Every month, some 1,300 ships heading to or from the Suez Canal must pass through the lawless waters off the coast of Somalia. Pirate attacks are at an all-time high—more than 200 have already been reported this year. As of May, pirates were holding more than 500 hostages and 26 hijacked ships, and companies are losing up to $8.3 billion a year.

For a few short weeks last September, the Northwest and Northeast passages through the Arctic Ocean were simultaneously ice-free from end to end, the first such clearing in the time that satellites have monitored the region. Merchants have long sought routes through the ice packed waters that link the pacific and Atlantic. But researchers at the Naval postgraduate school in Monterey, California, say that we could now see an entire Arctic Ocean, not just passages along the coasts, with icefree summers, as soon as 2016.

The basic unit of the global economy is the humble container. Every year, a vast fleet of freighters hauls more than 17 million of them to destinations around the world. Now the ships are getting bigger, the routes are getting better, and the ports are getting smarter than ever before. Oh, and for a longer-term look at the future of shipping, check out Cargotec's plan for Port 2060.

One of the great features of Apple devices is AirPlay, the technology that enables them to wirelessly stream media to one another. The company has also set out to enable a growing range of other equipment, such as A/V receivers and speaker docks, to get content from your iTunes library simply by being near your computer or iOS device. Still, AirPlay has some Apple-imposed limitations, including the required use of iTunes and a relatively small pool of supported third-party devices.
When you need to remove a tree stump, you have several options. Sissies call a tree service. Tough guys loop a chain around the stump, hook it to the bumper of their truck, and find out which one is stronger. Others use gunpowder to blow them up, though this is not advisable in most jurisdictions (unless your cousin is the sheriff and you let him watch). But my favorite method is to convert the stump itself into gunpowder and then burn it up. That is the secret behind how chemical stump remover works.

Over the past five years, 12-volt battery-powered tools have been rapidly replacing their corded counterparts. Among these upgrades, the Rockwell Trans4mer merges the portability of a 12 volt with true versatility, combining a jigsaw and a reciprocating saw into one shape-shifting 2.6-pound tool.
You might have heard of Google's Chrome OS, and how it's essentially a computer with a web browser...and nothing else. How can a web browser replace all the other elements of a computer? It turns out, with more ease than you'd think.

The idea of a robot assuming control of your car takes some getting used to. But the race to build increasingly autonomous automotive safety systems is well under way, as the cost of cameras and sensors drops and engineers get better at programming those tools to work together.

John Underkoffler looks at his desktop computer and sees an outmoded, inadequate tool. Trackpads and touchscreens, the former MIT instructor says, are limiting. Don’t even get him started on the mouse. The future, he says, is in gesture recognition-based interfaces, which he calls “spatial operating environments,” or SOEs.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
