Lab accidents do happen. Fortunately they’re rare because of safety measures. Unfortunately, this also makes people lazy about following safety guidelines.
Earlier, Labrigger covered the danger of retinal burns with lasers.

The Society for Neuroscience (SfN) have compiled and are curating a large collection of online resources for neuroscience teaching. It’s called ERIN (Educational Resources in Neuroscience).
Some examples:

To recap the previous post on axial resolution and numerical aperture in two-photon microscopy:
For excitation deep in scattering tissue, higher NA can actually be detrimental because the light cone…
Recently, microscope manufacturers have been releasing ever higher NA objectives for multiphoton imaging. Although higher NA objectives should give better axial resolution, they might not be ideal for imaging deep into…
As previously noted, homemade cables are to be avoided. However, stock cables are not always up to spec. For example, if one wants to drive stepper motors using a…

Roger Tsien’s lab recently published the new generation voltage sensitive dye they were presenting at SfN: VoltageFluors. As often when then Tsien Lab takes on a new field, they start by taking a…
Thorlabs and Newport have offered 3D models of their products for a long time. However, they’re typically in formats for expensive programs like SolidWorks and AutoCAD. In the past year or two, Newport has been slowly adding to their library of Google SketchUp models.

Like many of you, I went to monster truck show last weekend.
The competition reminded me MATLAB’s new thing: Cody.
It’s a bunch of problems posed as MATLAB coding tasks. For example:
Find the mean…
On the topic of MATLAB learning materials (covered previously here and lots more MATLAB stuff here), MIT has some online courses freely available. Here’s an “aggressively gentle” intro to MATLAB,…

Apple’s Safari web browser v5.1 has an annoying behavior where tabs reload/refresh like crazy. This can cause lost work and data.
Disable the problematic behavior this way:
1. Close Safari
2. Open a terminal and enter this command
defaults write com.apple.safari IncludeInternalDebugMenu 1
3. Restart Safari. You should see a new menu to the right of…
