When authorities in Egypt shut down Internet connections during last week’s uprising, hackers around the world started scrambling to create a work-around. Before they could succeed, the blackout was lifted. But now people are worried that similar shutdowns might occur in countries like Jordan, Syria, and Yemen—and so hackers are working to set up alternative networks in those countries, just in case.
Considering that anxiety makes your palms sweat, your heart race, your stomach turn somersaults, and your brain seize up like a car with a busted transmission, it’s no wonder people reach for the Xanax to vanquish it. But in a surprise, researchers who study emotion regulation—how we cope, or fail to cope, with the daily swirl of feelings—are discovering that many anxious people are bound and determined (though not always consciously) to cultivate anxiety. The reason, studies suggest, is that for some people anxiety boosts cognitive performance, while for others it actually feels comforting.
It sounded like a panacea for climate change: “geo-engineering” the atmosphere to block some sunlight and counter global warming. Now scientists scrutinizing the approach say it could produce dangerous cascade effects, severely disrupting weather and agriculture—and might fail to block the worst of the greenhouse effects anyway.
For people who already have their hands full keeping up with Facebook, scanning Twitter tweets, and answering email too, here’s a heads-up. The cool kids and big egos of Silicon Valley are busy colonizing a new social network—and soon you may want to as well.
As protests continue in Egypt, the government has cracked down by suspending the country’s Internet service and disrupting much of the cell-phone coverage. Reporters Without Borders closely monitors how nations restrict the Internet access of their citizens. Here are the worst violators.
Cory Booker used Twitter to help dig out residents of Newark during the last blizzard. Now, with much of the Eastern Seaboard covered in snow, more Americans implored the mayor to come to their aid. While Booker can't be everywhere, ordinary citizens inspired by his example often heeded the call.
The history of televised fitness is almost as long as the history of television. From syndicated shows to videos on demand, exercise shows have been capturing our attention for years—and making their stars national icons. Here’s a look at some of the most notable figures and biggest milestones in fitness TV.
If you follow the news about health research, you risk whiplash. First garlic lowers bad cholesterol, then—after more study—it doesn’t. Hormone replacement reduces the risk of heart disease in postmenopausal women, until a huge study finds that it doesn’t (and that it raises the risk of breast cancer to boot). Eating a big breakfast cuts your total daily calories, or not—as a study released last week finds. Yet even if biomedical research can be a fickle guide, we rely on it.
Apple CEO Steve Jobs has gone on a medical leave. With luck this will be temporary, like his last medical leave, in 2009, when Jobs, a survivor of pancreatic cancer, received a liver transplant. But what if he doesn’t come back? Ever since the previous time, people have wondered if the company could carry on without him.
NASA’s Spinoff 2010 report, which the agency publishes annually to promote the commercial applications of its investments in technological research, highlights a number of innovations that affect our lives every day. Here are some of the highlights.
With Apple CEO Steve Jobs back on medical leave—an indefinite one, unlike his last break—the company’s investors, $300 billion worth of them, are forced to envision a post-Jobs Apple. And they didn’t like the thought: shares fell as much as 10 percent before rebounding in overseas trading Monday.
The new year brings some radical new experiments in online media. First up is The Daily, a publication created by Rupert Murdoch’s News Corp. that’s set to launch this month. You won’t be able to read The Daily on a plain old Web browser. It will exist only as an app on the iPad (and, presumably, later on other tablets as well)—and you’ll have to pay $1 a week for a subscription.
It’s probably not going out on a limb to say that John Boehner’s waterworks—the man cries when his party wins control of the House, when he thinks about kids, when he walks down the House aisle to take the Speaker’s gavel—are not meant to reduce sexual arousal in women.
Tim Ferriss is one of those personalities you want to hate, a guy so wildly successful it’s almost comedic. His productivity manifesto, "The 4-Hour Workweek," was an instant New York Times bestseller when it debuted in 2007, despite Ferriss’s not knowing the first thing about publishing.
To any woman having surgery for breast cancer, the words she most wants to hear in the recovery room are, “We got it all.” But if she wants to find the surgeons who have the best track record on the most important measures, she might as well throw darts at a printout of oncologists.
My wife and I first noticed our friends’ preoccupation with autism and vaccines in late 2007, right around the time former TV star and Playboy Playmate Jenny McCarthy published the first of several bestsellers in which she claimed that the measles-mumps-rubella (MMR) vaccine had probably given her son autism.
Even before their midterm debacle, Democrats couldn’t pass an energy-climate bill worth the name. Prospects for legislation to free the country from dependence on petro-dictators—and put it on a path to a renewable energy-based economy—would seem, therefore, about as likely as John Boehner introducing a $700 billion stimulus bill. So why are renewable-energy advocates smiling?
In terms of being the director of NIH, I don’t think anybody who’s worked with me would be able to identify a circumstance where my personal beliefs about faith have in any way interfered with my role as a scientific leader.
Thanks to sophisticated imaging technology and a raft of longitudinal studies, we’re learning that the teen years are a period of crucial brain development subject to a host of environmental and genetic factors.
In 2003, after the dotcom bubble burst, technology guru Tim O’Reilly threw a party. His company, O’Reilly Media, hosted a free “un-conference” to celebrate technology—and declare that it wasn’t over. This was the first of the much-hyped Foo (Friends of O’Reilly) camps, a sort of Woodstock for technophiles like Amazon founder Jeff Bezos and Google cofounder Larry Page.
Allergies can develop when young bodies come into contact with a new substance, and an increasing number of kids have early exposure to tech tools and “adult” products that can lead to a lifetime of reactions.
Katherine Edmonson, a singer and songwriter in Austin, Texas, is finding her career on the upswing. Previously, she played regular gigs in bars and restaurants around Austin, but she has graduated to playing shows at music venues and theater spaces throughout the city. But even as she finds more success, she’s still trying to make ends meet.
Since the illness first surfaced in the U.S. in the ’80s, chronic-fatigue patients have endured skepticism from doctors, who have not known what to make of a constellation of symptoms that has no known cause, no diagnostic test, and no specific treatment.
To those who are convinced that the science of global warming is sound, as well as to those on the fence, the refusal of climate scientists to attribute any single episode of extreme weather to greenhouse-induced climate change has been either exasperating … or suspicious.
Ancient Egyptians relied on a pregnancy test that was roughly 70 percent accurate: if a woman urinated on grain seeds and they grew—thanks to high levels of estrogen and progesterone in her urine—she was probably pregnant. Today, people still place a high premium on diagnosing themselves from the comfort of their own bathrooms.
