US scientists’ research on how to promote healthy eating in schools is deeply flawed, watchdog researchers have found. The original studies gained much media attention, secured millions of dollars in funding and are being implemented in thousands in schools. But independent scientists have found that they are filled with problems, including mathematical impossibilities and duplications. 

If you ever look up scientific theories online, it won’t be long until you encounter at least one story like this. Because science is a living subject and constantly evolving, scientists will inevitably disagree and controversy will arise. Choosing who to believe when you are not a subject expert yourself is tricky and confusing, especially if you are trying to use science to make an important decision. Here are 5 (or maybe 6) steps you might want to consider to make up your mind.

You have just woken up. You check your phone and have a look at the news. What do you see? Most days, a key headline will have something to do with science – and with good reason. We live in what many consider a golden age of discovery. Science is making advances we never thought possible and is helping us work out problems we never thought could be solved. We can look for water in outer space, use light-activated nanoparticles to kill antibiotic-resistant bacteria and use drugs to correct errors in our DNA to fend off deadly genetic diseases.

However, that’s only one side of the coin. At least half of the science news seems to be urgently pointing at a new problem. Just over the past few weeks, even the most casual news-readers could have found themselves worrying about involuntarily increasing their risk of getting breast or lung cancer by doing apparently healthy things like going outside and taking vitamins. You may have been stressing about compromising your heart’s health by sitting too much or being too tall. And that’s before you’ve even gotten out of bed!

So how can you use science to make more informed decisions? Here are a few pointers to empower you to make a change.

If you wanted to know more about a medical condition would you take a trip to the library and pore over medical textbooks? Of course not, you’d look it up on your phone while you’re still in your doctor’s waiting room.

Looking up things online is essentially second nature for most of us – but do you ever worry if you can trust what you find? Most of us get all our information from the Internet – and science and medicine have been made far more accessible by the Internet and mobile phones. It’s incredibly convenient, but it is also a minefield of potential misinformation, misunderstanding and, even worse, fraud. How can we know if we can trust what we see online? Here are some of my best pointers to use this amazing resource to obtain reliable and relevant information – especially when it comes to science and medicine.

Introducing ScienceSeeker

We're pleased to announce the unveiling of the product of six months of planning and work by some very dedicated volunteers. ScienceSeeker (at, naturally, Scienceseeker.org) is a beta-level site; a work in progress, but we think it's a very useful work even as it now stands. The project began as an extension of Science Blogging Aggregated, but quickly grew into an independent site.

The basic concept is simple: Find as many sources of regularly-updated science information as possible, and collect them all in one place. We believe that science blogs are currently the most robust and diverse source of science news, discussion, and commentary. They can offer a measured response to the myriads of self-promotional press releases that clutter newspapers and inboxes. Unfortunately, they are spread all about the internet, in dozens of blogging networks and hundreds, if not thousands, of independent science blogs. These blogs and networks aren't organized by topic, which makes it difficult for someone looking for latest posts on, say, chemistry.

ScienceSeeker already catalogs over 400 blogs, and is set up so that anyone can add more blogs. Our editors will review any submission to make sure it's really about science (and not spam), then approve it within 24 hours. Our aim is to be the most comprehensive and useful aggregator of science news, discussion, and commentary anywhere.

Take a look at the site and put it through its paces. We think you'll agree that it's one of the most useful and engaging science sites you've ever seen.

Click here to visit ScienceSeeker.

ScienceSeeker is an all-volunteer effort, and we intend to make it a formal, open-source project, allowing anyone to contribute enhancements. We have lots of ideas of what to do next, but we want to hear yours too. Feel free to offer suggestions in the comments.

Crowdsourcing request: Help us create a list of blogs for v. 2.0

Update: Thanks to everyone for your help! We've finished updating the database. Look here for news on our launch on Saturday, January 15.

In just under three weeks, we'll be unveiling the beta version of the next generation of this site.

The new site will work very differently from this one; it is a custom-created database that collects information from hundreds—and ultimately thousands of blogs. Users will easily be able to select just the topics they want, instead of seeing posts based on what network they are on. We want the beta site to be usable from day one, but to do that, we need some help.

I've created a Google Docs Spreadsheet for this purpose. Anyone can access the spreadsheet and make modifications. What we need are the name, URL, RSS address, and topic of each blog. What we have, in most cases, is just the URL. If everyone pitches in and visits 10 to 20 blogs, then we should be able to generate this information in a matter of days, if not hours.

Most of the blogs are listed on the Master Blog List (the first tab at the bottom of the spreadsheet). To start helping, just fill in the information in the space provided. If you figure out an automated way of doing this, you can reserve a block of blogs by typing your name in the designated column; then no one will duplicate your efforts.

The reason we need humans to do this is that we want the blogs to be classified by topic. We've generated a list of topics (on the last tab in the spreadsheet). When you visit a blog, figure out what topic from our list best describes the blog, and enter it in the space provided (most web browsers will display a drop-down menu to make this easy for you).

The other tabs are for blog networks that are a little more difficult to suss out; either there was no easy way for us to find a list of blogs, or there are non-science blogs mixed in with science blogs. So, we've given specific directions for what to do in each case.

FAQs

  • My Blog Isn't Listed!
    Don't worry! Either we've already got all the info we need (in the case of some blog networks) or you're an independent blogger and you'll be able to register your blog when the site launches. If you don't think you're in either of those camps, let us know in the comments below

  • None of the official topics apply to this blog
    Just pick the closest match. You can get more specific in the secondary topic

  • I don't agree with your list of topics
    We had to start somewhere. The list will be easily modifiable in the future.

  • One of the listed blogs is not scientific
    Explain your objection in the Notes section on the spreadsheet

  • Someone has reserved a block of blogs for hours
    You can use File --> See revision history to see how recently an update was made. If it's been more than an hour, feel free to delete their name, substitute yours, and work on that entry

  • There's no drop-down menu of topics
    Try using a different browser. I've tested it on Safari and Firefox, but I can confirm it doesn't work on Chrome for Mac.

  • What's in it for me?
    Our eternal gratitude? Plus, if we see you at a conference, we'll buy you a beer


Thanks again. Let us know if you have any other questions in the comments.

Building a better aggregator: Goals, Tagging

The ScienceBlogging site you see now was always intended to be a temporary solution. What we really need is a site that not only aggregates blog posts, but also allows users to classify them, search them, highlight their favorites, point their friends to them, and do many other things we haven't even imagined yet.

Behind the scenes, Bora, Anton, Jessica, Mark, and I have been discussing how to do that, but we realized that limiting the discussion to just ourselves is depriving us of a valuable resource: The people who'll be using and contributing to the new site.

So, over the next few days, I'll be offering some thoughts about how to proceed and inviting your comments. Our plan is to have at least a partially functional, working prototype of the new site by the ScienceOnline conference in January 2011. Let's get that started right now by discussing the goals for the site.

Goals
Here are the goals we came up with for the site:

  • To be a central site where scientists, media, other experts, and laypeople see what scientific topics are being discussed on blogs, in real time

  • To be a resource for locating past discussions

  • To promote science blogging and other online discussion of science

  • To promote scientific accuracy and avoid pseudoscience and crackpottery

  • To be encyclopedic and inclusive

  • To be searchable and filterable

  • To have a system (or multiple systems) for highlighting discussions and posts that are especially topical / high quality

  • To have a means of removing or hiding posts that are not scientific (e.g. vacation photos, political rants unrelated to science, etc.)

  • To be multilingual

  • To be open source / open access


Should anything be added, changed, or removed?

Tags
One of the first considerations will be how to keep track of all this information, and a huge key to that will be classifying it. That's why we think it will be essential to have a unified tagging system in place. If bloggers don’t select their primary tags from a central list, then it will be difficult for users to find posts on the topics that interest them. On the other hand, if bloggers must visit our site to choose primary categories, then usage will suffer. We can allow bloggers to set default tags for their posts using their registration page, but there should be some way to override those settings for individual posts, still using our list of preferred tags.

Could we create a WordPress plugin for this? Or adapt an existing plugin? What about other blogging platforms? What about templates that don’t support tags? One possibility is using a bookmarklet, which would be platform neutral but not ideal. Any other ideas on how to implement a tagging system?

That's just the first bit -- there's a lot more to discuss, but we thought this would be a good way to get the conversation started. So please, let us know what you think in the comments.

Some thoughts about science blog aggregation

(Adapted from two posts on Word Munger)

After the summer's "PepsiGate" affair and the subsequent departure of 20 or so bloggers from ScienceBlogs, I suggested that if the departing bloggers want to continue to have the kind of influence they used to have at ScienceBlogs, they need to do something more than just start or restart their old, independent blogs. They need to form a new network -- perhaps built around different principles, but a network nonetheless. They might choose to have a central site based on RSS feeds or some other aggregation system, but there needs to be a systematic way to connect their conversations. Otherwise, most readers will tune out. It's simply too much work for most readers to follow a diverse set of disconnected blogs. Social networking sites like Twitter can bring important individual posts to light, but are less effective at sharing the extended conversations that go on between blogs.

Sure, there are some other burgeoning science blog networks, but none seem to be prepared to assume the ScienceBlogs mantle (which ScienceBlogs itself hasn't actually yet ceded). There are also some lists of all the bloggers who've left ScienceBlogs, but they don't capture all the other science bloggers who were never a part of ScienceBlogs, or the many excellent bloggers who chose to stay.

To me, the obvious next step would be to find some way of collecting all these disparate voices in one place. Sure, ResearchBlogging does some of that, but it only captures posts specifically about peer-reviewed research, which is probably less than ten percent of what scientists and science communicators actually blog about.

One idea that shows promise, at least as a stopgap, is to use an existing social network to do the task. There's already discussion over at Friendfeed about doing just that. The advantages of such a system is that Friendfeed already has tools in place to help people "like" and "dislike" posts, discuss them, and so on.

To see how this might work, I created a FriendFeed group for Anthropology, based on blogs registered with ResearchBlogging.org. You can check it out here. But this isn't all Anthropology blogs, or even all Anthro blogs registered with ResearchBlogging -- I cheated a bit because my default report of regisered blogs doesn't include RSS addresses. I only used blogs from Blogger and Wordpress since their RSS URLs are easily reproduced based on the blog URL. And there are other problems. Many blogs cover multiple topics. How would you decide how which list(s) to put them on? What if someone started posting pseudoscience, or moved their blog? Who would be in charge of monitoring the list to make sure it remains useful? And how many people would actually register with FriendFeed just to follow blogs? The beauty of a site like ScienceBlogs is it stands on its own -- you go there to read blogs about science. Someone who's only interested in science (and not social networking) is less likely to hang around a site like FriendFeed just to read science blogs. I'm unconvinced that a set of feeds could have the same influence as a dedicated science blog aggregator.

In the wake of these thoughts, Bora, Anton and I came up with something we think is at least a little better. This site is sort of an aggregator of aggregators. We're letting others do the work of collecting blogs into bundles; we're just sharing all those bundles. If other bundles are promising, we'll add them to the aggregator here, with a minimum of fuss. It's not ideal -- I think the ideal aggregator would have more active curators, and a way to sort through all the posts by topic -- but it's certainly a good start. Let us know what you think.
