By WWII, scientists had already begun looking at alternative gelling substances for routine use in bacteriology, but concluded that agar was still better as it is both firmer and easier to handle. Today, some specialized microbiology applications use the colloid carrageenan (extracted from red seaweed Chondrus crispus, or “Irish Moss”), a more transparent and less auto-fluorescent alternative to agar (agar emits its own background fluorescence when excited by light). However, for routine bacteriological use, carrageenan is more difficult to dissolve, requires higher concentrations, can degrade at high temperatures, and forms weaker gels, which may result in puncturing its surface during the plating of cells.
Workspaces now have an animated pressed state and expand to accept drops when in multitasking view. Plus, you can now uninstall apps or view them in AppCenter from their secondary-click menu, just like you can from the applications menu. And, we fixed issues with the dock’s appearance in screenshots on HiDPI displays and where the dock could become invisible in Classic sessions.
