In a previous post I played around with Amazon Glacier, using a tool called glacierFreezer. Since then, I’ve wanted to automate backups of my Time Machine archives, as well as my photos and home directories. Looking around for more current Glacier interfaces I noticed a project called glacier-cmd which looks promising. The core utilities are written in Python, and provide means to upload, download, and query Glacier vaults.
Last year it was just a rumor, but yesterday Retraction Watch covered an official retraction from a neuroscience lab at Hopkins. The retraction notice:
Our paper reported an analysis of a mouse genetic model that deletes the C terminus of Shank3 to mimic human mutations that cause autism spectrum disorder. Figure panels for several polyubiquitination assays were improperly assembled, leading to multiple repetitions of bands in western blots of the lysates. These errors did not affect the quantitative analysis of polyubiquitination because this analysis was performed as described and was not dependent on representative western blot images. In light of the figure preparation issues, we feel that the most responsible course of action is to retract the paper. We sincerely apologize to the scientific community for any misunderstanding that these errors may have caused.
Well done for preventing the spread of misinformation. It must hurt to issue a retraction, but it sounds like the conclusions still stand regardless of the “improper assembly” of the representative Western blots. When are we going to learn to stop trusting Western blots in papers?
I really appreciate all the feedback. You’ve made my day and my new year!
The Raspberry Pi is a fairly powerful $25 single-board computer targeted toward the educational market, though just because it’s for kids doesn’t mean it’s not fun for adults. I’ve been wanting to buy a Pi for a while now, but couldn’t justify purchasing hardware I have no use for – that is, until I saw this blog post detailing how to use the Pi as an Apple Airplay receiver. This is perfect. Let’s get started turning our little computer into a single-purpose appliance.
I recently bought a really fun mini RC helicopter. It’s made in China by WL Toys, and it packs lots of technology into a ready to fly kit. Flying it has been a blast, but the manufacturing quality control leaves something to be desired. The remote control has a small piece of something rattling around in it, which doesn’t affect the function at all. The battery charger is supposed to charge two of the Li-polymer batteries simultaneously, but it seems like mine only has one working port:
