Just messing around up on Mt. Lemmon again. I climbed up some rock near the top to try and get a panoramic for the first time, but that didn’t work out so I got this instead. There were other people up there as well but they were down where I took these photos, and of course we were having laser battles! They ended up being people I knew which was really cool, one of them being a photographer (check out his work).
I’m also on: Flickr // 500px
Some shots I got while watching the Camelopardalid meteor shower this weekend. Not so much a meteor storm, at least where I was watching anyway, it was still pretty decent tho. Saw a couple of meteors, usually relatively big ones. The meteor in the first pic on the right traveled really slowly and took about 3-4 seconds to burn up, really cool to watch. Love this stuff! Follow me on Flickr or 500px if you’d like, higher-quality pics on those sites. Still deciding whether or not I want to get back into regular science-blogging, probably will sometime soon. Anyway see you all around, keep looking up!
Actually brought my good camera out during sunset for once
I’m kind of proud of these. Fucking gorgeous sunset amiright? On flickr also.
This is basically what I did over winter break, just blog on the interwebs, hang out with friends, stargaze, some photography, hiking and jog around sunset pretty much everyday while listening to podcasts like SGU. Twas a good break indeed. Now the semester has started again and I will be focusing on that so expect fewer posts from me. This is my official goodbye since I kind of just stopped posting things without any warning last semester, oops. There are plenty of other science blogs out there tho so don’t worry, #Science is a good place to start.
My High School Chemistry Cheat Sheet
4 years later and I still use this, it has been good to me. Not sure how or if I should credit this, it was just a hand-out my teacher gave us all at the beginning of class and I couldn’t find anything like it online so I just scanned it.
Was out near the Kitt Peak Observatory for this. Stacked about 30 different photos together using ‘Lighten’ and gradually brought up the opacity to give the comet-tail effect. Showing about 15 minutes of Earth’s rotation.

Dream On: Why Sleep is So Important
This infographic showcases some studies on just how dangerous—and costly—sacrificing sleep can be, and it concludes with some facts on how you can try and improve your sleep quality if it’s something you struggle with.
Fact of the Day:
Persistent Pupillary Membrane (PPM) is a condition where remnants of the pupillary membrane, which covers the anterior surface of the lens during embryonic development, sustains as thin, web-like strands of connective or vascular tissue across the pupil. It rarely interferes with vision and usually deteriorates of its own accord. In rare, severe cases, it can be treated with laser eye surgery. Further reading: http://goo.gl/HVw6mD

The first of the 2014 meteor showers – The Quadrantids –
peak on 3rd January. It is estimated that they will hit somewhere between 60 and 120 meteors per hour.
To find the Quadrantids’ radiant - the region in which the meteors seem to emanate - look for the constellation Boötes in the east-northeast sky. Observers can look forward to dark skies since the night sky will be Moonless.
The meteor shower is predicted to climax around 19:30 Universal Time or or 2:30 PM Eastern Standard Time (EST). This places the northern Asia region in the best position to watch the show, though all northern hemisphere observers are encouraged to watch past 11 PM local worldwide. Remember: meteor showers are fickle beasties, with peak activity often arriving early or late. If you want more information, try Sky and Telescope/Universe Today/ Time and Date/Bad Astronomy
Totally forgot about this! Gonna get some pics!
I doubt rates will get as high as 120/hour, maybe 60 tops with an average rate of ~25. Apparently this meteor shower will peak at a much better time next year, near midnight instead of late-morning like this year, but there’s a full Moon then so watch it now unless you want to wait until 2016.
You will see higher rates the more north you live, since Bootes is near the North Star. And hey, there’s no bitchass Moon to ruin everything this time, yay!
Species in the Rhinochimaera family are known as long-nosed chimaeras. Their unusually long snouts (compared to other chimaeras) have sensory nerves that allow the fish to find food. Also, their first dorsal fin contains a mildly venomous spine that is used defensively. They are found in deep, temperate and tropical waters between 200 to 2,000 m in depth, and can grow to be up to 140 cm (4.5 ft) in length.
Chimaeras (also known as ghost sharks and ratfish) are an order of cartilaginous fish most closely related to sharks, but they have been evolutionarily isolated from them for over 400 million years.
"Watch what happens when force is applied to amazing and mind bending Non-Newtonian Liquid and filmed in slow motion."
What is it?
"An inexpensive, non-toxic example of a non-Newtonian fluid is a suspension of starch (e.g. cornstarch) in water, sometimes called “oobleck” or “ooze” (1 part of water to 1.5–2 parts of corn starch].  Uncooked imitation custard, a suspension of primarily cornflour, has the same properties. The name “oobleck” is derived from the Dr. Seuss book Bartholomew and the Oobleck.”
"Taken by Igor Siwanowicz, the photo shows the open trap of an aquatic carnivorous plant known as a humped bladderwort (Utricularia gibba). The plant floats in water waiting for its prey to touch its trigger hairs, which cause the plant to open its trap so quickly that it sucks in water as well as some unlucky microinvertebrates. The pretty little flakes near the bottom of the image are single-cell algae that live inside the trap. The image is magnified 100 times." Via.
The ability of a dragonfly nymph to successfully snatch and grab food is directly related to its anus. The mouth-grabber (labium) is hydraulically activated. The dragonfly draws water in through the anus, clenches, then compresses its abdominal and thoracic muscles against the water-filled rectal chamber. This raises the internal body cavity pressure, and pushes the labium out –in a strike that takes 10 to 30 milliseconds.
The amount of internal pressure generated is about 6000 Pa, or 6 kPa; equivalent to 0.87 psi (pounds per square inch). That doesn’t seem like a lot, until you consider that big nymphs only weigh 100mg (0.0002 lbs), so generating almost a pound of pressure WITH THEIR BUTT is pretty impressive. A Camaro turbocharger produces 7 psi, so you could say this little insect has 1/7th of a Camaro in its ass.
The other amazing function of a dragonfly nymph rectum is jet-propulsion. By un-clenching their rectum, water in the rectal chamber can be jetted out at high pressure, pushing the nymph forward through the water. The forward thrust generated is 1.5 g in 0.1 second; nymphs’ top speed is 10cm/second. They can throttle their rectum back to produce varying amounts of thrust through the water.
But Wait! There’s More! The jet-propulsion butt-hydraulic system also is a gill. Dragonflies breathe through gills in their rectums; you can see some great photos of that above. Because dragonflies breathe through feathery gills, they are sensitive to lots of forms of aquatic pollution. (via Here Be Dragons - Wired Science)
