There's a certain comfort that comes from knowing a fact. The sun is up in the sky; there's nothing you can say that's going to change that. You can't say, "The sun's not up there, there's no sky." There is reality, and there's nothing wrong with accepting reality.

Item #1: Astronomers find that the mean thermal energy density of gases in the universe has been increasing, and is now 2 million Kelvin, 10 times hotter than 10 billion years ago.[6]
Item #2: A new study finds that programs which demolish abandoned properties reduces nearby crime rates.[7]
Item #3: A paleontology student has discovered that a fossil collection of ancient sharks in two UK museums are actually pterosaurs, including a previously unknown species.[8]

Notes
- ↑ From the notes from the Carbon Ladder YouTube video:
These sounds were produced by living fungi: Shitake mushrooms still attached to their mycelial bodies. A mushroom is actually the fruiting body of a fungus, the "body" of which consists of the mycelium, a network of root-like structures that run through substrate (the log, compost, sawdust, etc.). A mushroom still connected to a growing mycelium produces a varied and interesting rhythm, while a mushroom that has been picked produced only a static tone.
All living organisms produce a faint electrical current, which constantly fluctuates according to the state of the organism. This current can be amplified and used as a control signal for an oscillator, producing a sound which directly reflects the state of the organism.
For my installation "Ha, Ha! Your Mushrooms Have Gone?", fungi actively growing on their original substrate were housed in glass tanks, to preserve optimal humidity. Visitors to the installation were able to hear the sounds of different living fungal cultures, which changed as new specimens were brought in during the course of the work. The bioelectrical sounds from the fungi are switched on and off by infra-red sensors, in response to the movements of people in the room, allowing visitors to interact with the work. Perhaps the fungi also respond to the sonic vibrations in the room.
