3:10 AM | Pink Clouds and Science Reruns
A pink cloud was reported in the early morning, (pre-sunrise), sky over Arizona on Wednesday[1]. NASA and the DOD soon thereafter took credit for the cloud.  They had launched a rocket into the ionosphere where it released a vapor that created the cloud.  The purpose of the experiment was to study the effects of the vapor on the ionosphere itself.  The article, referenced above from ABC, said:"The experiment, which also involved using ground stations to take measurements of the […]

6:30 PM | Superconductors: trains and cons
“We have 30 minutes of ratchet fighting in supermarkets, 15 minutes of bloody images of war and 20 minutes of sports. What are we doing in the two-minute long science section? I like that superthing. Super sounds good. They’ll love it.” — Every night news producer Superconductors are one of those sciency-sounding headline makers with…

Smart vents to save energy – CES 2015 NSF-funded small business Keen Home has developed a smart vent that opens and closes to reduce uncomfortable hot and cold spots, save energy in unused rooms, and tailor a home’s heating and cooling to fit specific lifestyles. The new wireless system will respond automatically based on users’ habits and presence. Keen Home co-founder Nayeem Hussain explains how the smart vents integrate into daily life. Keen Home is funded through […]

3:03 PM | Many Worlds Are Never Exhausted
There have been some good comments on last week’s post about the Many-Worlds Interpretation, which I find a little surprising, as it was thrown together very quickly and kind of rant-y on my part, because I was annoyed by the tone of the original Phillip Ball article. (His follow-up hasn’t helped that…) But then maybe…

2:19 PM | “My God, it’s full of planets!”
Researchers assume there are at least 50 billion planets in our Milky Way. With this famous quote from the movie “2001: A Space Odyssey”, the international press commented this estimate, based on the results of the Kepler space telescope. Among those planets, at least 500 million orbit their home star within the “habitable zone” – […]

“End? No, the journey doesn’t end here. Death is just another path, one that we all must take. The grey rain-curtain of this world rolls back, and all turns to silver glass, and then you see it.” -J.R.R. Tolkien No matter how well we care for our bodies, they eventually wear down, give out, and…

Potential Energy Paul Andersen explains how conservative forces can be used to store potential energy in an object or a system. The work done is equal to the amount of potential energy in the object. The following conservative forces are described; gravitational, spring and electric force. The difference between a conservative and nonconservative for is also included. By: Bozeman Science.

4:40 PM | The Story Behind Earth's "Other" Moon And Its Completely Whacked Orbit
We all know and love the moon. We're so assured that we only have one that we don't even give it a specific name. It's just The Moon. But the moon is not the Earth's only natural satellite. Here's what you need to know about 3753 Cruithne and what its weird orbit reveals about the solar system.Read more...

You wouldn’t know a limpet had teeth from looking at it. These soft, squishy sea snails cling to rocks and scrape algae into their mouths, which means their teeth need to be stronger than rock. Last week, a paper in the Royal Society’s journal Interface published the results of a limpet tooth stress test. It turns out that these teeth are the strongest biological material on the planet. (We wrote about graphene a few months ago, which is one of the strongest human-made […]

Nobel Laureate Sydney Brenner has criticized systems biology as a grandiose attempt to solve inverse problems in biologyLeo Szilard – brilliant, peripatetic Hungarian physicist, habitué of hotel lobbies, soothsayer without peer – first grasped the implications of a nuclear chain reaction in 1933 while stepping off the curb at a traffic light in London. Szilard has many distinctions to his name; not only did he file a patent for the first […]

2:25 PM | Waldo e la strada verso la miniaturizzazione
Waldo E. Jones sembrava fluttuare nell'aria al centro di una stanza sferica. L'impressione derivava dal fatto che fluttuava davvero nell'aria. La sua casa era inserita in un'orbita libera, con un periodo di poco più di ventiquattro ore.(8)Waldo abita nello spazio. In orbita intorno alla Terra. Soffre di una malattia che gli impedisce di muoversi sotto l'azione della gravità terrestre. Questo impedimento, come si suol dire, gli ha aguzzato l'ingegno, permettendogli di diventare […]

11:23 PM | Flatbread physics
“You must use a bread machine.” That’s the most common response when I reveal that I bake bread. Though I do have a bread machine, I seldom use it any more. For many, though, the limitation to making bread is the absence of an functional oven (I have heard anecdotes of ovens being used exclusively to store kitchen paraphernalia). In many parts of the world, owning an oven is a luxury - but that does not exclude one from exploring the range of flatbreads. Flatbreads […]

10:43 PM | Numbers Game (Synopsis)
No one science can stand wholly on its own. For inquiry about the Universe to give a correct, complete picture, it requires that we bring in a whole slew of evidence, often from tangentially related fields. The interplay between three fields in particular — astronomy, physics, and math (not a science, but the tool used…
