Quadrantid Meteor Shower Tonight: How to Watch Online

Stargazers around the world are hoping for clear skies when the first meteor shower of 2013 peaks tonight, but if foul weather does spoil your view, don't fret. You can also track the meteor shower online.

NASA scientists at the Marshall Space Flight Center in Huntsville, Ala., will provide a live webcast of the Quadrantid meteor shower tonight through Friday (Jan. 2 to 4), to capture the peak of the annual "shooting stars" display.

You can watch the meteor shower on SPACE.com here, courtesy of NASA's webcast.

"Peaking in the wee morning hours of Jan. 3, the Quadrantids have a maximum rate of about 80 per hour, varying between 60-200," Marshall center officials explained in an announcement. "Unfortunately, light from a waning gibbous moon will wash out many Quadrantids, cutting down on the number of meteors seen by skywatchers."

The Quadrantid meteor shower occurs every year in early January when the Earth passes through a stream of dusty debris cast off by the asteroid 2003 EH1, a space rock that astronomers suspect is actually a chunk of a centuries-dead comet. The shower appears to originate in the eastern sky from the outdated constellation called Quadrans, which is located near the northern tip of the constellation Bootes, the Herdsman, NASA officials said.

According to NASA, the Quadrantids will peak between midnight and 3 a.m. (your local time), with the best views expected for stargazers in the Northern Hemisphere, though the display should be visible from anywhere on Earth north of the latitude 51 degrees south.

"To view Quadrantids, go outside and allow your eyes 30-45 minutes to adjust to the dark. Look straight up, allowing your eyes to take in as much of the sky as possible," NASA officials advised. "You will need cloudless, dark skies away from city lights to see the shower."

If you do venture out to see the Quadrantids, here are some other useful tips:

Dress warmly:?Since the best sky show will be in the Northern Hemisphere, where winter is in full swing, you will want to wear extra layers to ward off the chill during your observing period.

Get comfortable:?A comfy reclining outdoor chair or blanket may be just the ticket for a long night of meteor-watching. Your neck will thank you in the morning.

Look straight up:?NASA scientists have said the best way to watch a meteor shower is not to strain your eyes at the shower's radiant ? the patch of the sky where it appears to emanate from. Looking straight up is the best method to see any meteors or fireballs during the night.

Big Data: Can We Predict Population Trends (Like Happiness) via ...

Big Data: Can We Predict Population Trends (Like Happiness) via Health Apps?More than five years ago, I penned a piece entitled Reliability and Validity in a Web 2.0 World. It spoke about the concerns of gathering data from biased samples ? without first understanding in what ways, exactly, those samples may be biased.

Now, with the ubiquity of apps ? downloadable programs for people?s smartphones ? I?m seeing the same problem arise. Developers and entrepreneurs are pursuing data from these apps without understanding the basics of good, reliable, scientific data collection. And why it matters ? especially when you start wanting to analyze all of this ?big data? (a somewhat silly term? in epidemiology, for instance, scientists just call it ?data?).

Can personal health data be collected by these apps without bias, and somehow be transformed into measuring something bigger?

The short answer: no, not easily.

Sure, there are people who are part of a ?quantified self? movement ? who want to track and measure every aspect of their personal health (and assumedly, mental health). But those people are currently outliers, and in no way representative of the population in general.

Such minorities can quickly make up the majority of an effort to collect larger datasets in order to analyze health or well-being trends. While the resulting analyses can tell you something about this group of people, it would be inappropriate to suggest it generalizes to the rest of the population (who, demographically and behaviorally, may look and act very differently).

This won?t change anytime soon, because most health apps are downloaded by people, used once or twice, and then abandoned. There?s a reason most people stop using health apps ? especially ones meant to act as a data diary. They?re boring! Collecting data on yourself is just a very boring task for most of us to commit to actively doing every day (or even every week).

The Complicated Answer: Apps Need to Be Smarter, Connected

Health apps meant to collect data ultimately fail because they require active input by the user. This is why personal health records have largely never taken off in any meaningful way. People are too busy living their lives to be bothered with telling an app what their daily metrics are.

For health apps to ultimately succeed where most other attempts at personal health tracking software has failed is for them to collect their data passively. That means that no input from the user is required.

Of course, we?re a far way from such metrics providing meaningful data. Sure, there are running devices that track how much you run (from Nike, of course). But a running app is useless if it doesn?t talk to my diet app, or my nutrition app, or my exercise app. Or my mindfulness app. It?s one app measuring a single metric in the complex being that is me. It simply isn?t much to go on.

Trust is a Key Cornerstone

Adoption of such networked apps sharing all of your health data have another, less technical, obstacle as well ? trust. Companies like Facebook and Nike ultimately answer to only one set of people ? their shareholders. That means that if it?s in their best interests to analyze your data for things they can make money off of, they will.

Startups are no better, because instead of shareholders, they answer only to venture capitalists ? money lenders who are only looking for the best and quickest return on their investment.

Why would I want to trust my health information ? data that could be used against me for future denial of insurance or setting of my insurance rates ? to companies who have little interest in protecting my privacy?

Which brings us back again to the first point ? a biased sample. People who gladly give all of their health information to for-profit companies to analyze, collate, and eventually associate back to you (even if such data is initially anonymized) are not like most people. Most of us still care about keeping our health information to ourselves, just as most of us still want to keep our financial information to ourselves.

Where We Go from Here

Attempting to gather population-based data (e.g., conducting epidemiological research) from health apps has some issues and opportunities I?ve identified:

  • Biased sampling because of the tiny minority of people who actively and continuously use health apps
  • Sampling and continued usage could be improved by passive versus active data collection
  • Sampling and use could be further improved by use of a trustworthy authority to collect and store data (not a for-profit company or startup)
  • Apps that are aware of one another and exchange relevant health data about me are the next generation ? instead of the current wealth of siloed, unaware (stupid?) apps

I think it?s great that developers look at a health problem, develop an app for it, and release it to the world. But all too often these apps go nowhere, with no audience. Or they are orphaned by the original developers for lack of interest. The few popular health apps that gain a robust audience are the exception, not the rule. And even when they do gain widespread acceptance, just like our country?s electronic medical record systems, they don?t talk to one another.

If you want to be able to say something authoritative or meaningful about data collected from an app, you have to show that data comes from a representative sample of the population. Lacking that, your data only tells us about one tiny group in the population ? one that doesn?t look like most of us.

Minimum wage gap grows wider between states

OLYMPIA, Wash. (AP) ? With a bump in the minimum wage to $9.19 an hour on Tuesday, high school student Miranda Olson will edge closer to her goal of purchasing that black Volkswagen Beetle she's been researching online.

Olson is only able to pick up part-time hours, working after classes and on weekends. But the extra pennies she'll earn in 2013 will add up over the coming weeks and months.

"It's not much, but it's something," said Olson, 16, who works at Wagner's European Bakery and Cafe in Olympia. "Every bit helps."

Many workers around the country won't be as lucky as the ones in Washington state, which is raising its salary minimum even though it already has the highest state baseline in the country. Workers one state over ? in Idaho ? will make nearly $2 per hour less in 2013.

Automatic minimum wage increases designed to compensate for inflation have steadily pushed up salaries in some states, even through the recession, expanding the pay gap between areas that make annual adjustments and those that don't. Of the 10 states that will increase the minimum wage Tuesday, nine did so automatically to adjust for inflation.

Rhode Island lawmakers approved that state's wage increase this past year.

Paul Sonn, legal co-director at the National Employment Law Project, said he hopes more states will start looking at automatic adjustments as the economy recovers. He said the model ? which Washington state first adopted in 1998 ? helps avoid sudden jolts as states try to catch up to their peers.

"We think there's a case that it's better for everyone, including the business community, to have predictable, regular, small increases every year," Sonn said.

The automatic adjustments aren't much. Washington's bump of 15 cents will mean those who work 40-hour weeks will earn an extra $6 per week ? enough for a couple lattes ? or about $300 per year.

Hundreds of thousands of workers are expected to get a pay increase with the wage adjustments that begin New Year's Day. Along with Washington and Rhode Island, the changes will also occur in Arizona, Colorado, Florida, Missouri, Montana, Ohio, Oregon, and Vermont.

Between the nine states with automatic adjustments happening this year, the average minimum wage is $8.12 per hour, up from a little under $8. States that do not have automatic changes operate with an average minimum wage of about $7.40 ? a difference of about $1,500 per year for a full-time worker.

Many states, including Idaho, follow the federal minimum wage of $7.25 per hour, either because they've tied their minimum wage to that threshold or because the state-enacted minimum is lower than that.

San Francisco has set the highest local minimum wage and will have workers paid at least $10.55 an hour in 2013.

Groups like the National Restaurant Association oppose further increases in federal or state minimum wages, arguing that it's an ineffective way to reduce poverty and forces business owners to cut hours, raise prices or lay off workers.

At Tom's 1st Avenue Bento, a downtown Portland lunch spot, owner Tom Hume said he boosted pay for minimum-wage workers before the end of the year in order to get ahead of the game. He also raised prices on one-third of his menu items by 25 cents.

Natasha Baker, 22, who works at Hume's restaurant, recently moved back in with her mother but hopes to move to another apartment in January. She said the extra $5 or $6 she's earning every week with the salary boost is OK but won't make a huge difference.

"I don't usually look at what I get paid," she said. "I'm more directed on what's being taken out, which is more discouraging than anything."
