Enlarged Heart
The differences between a normal human heart and one enlarged by alcoholism and high blood pressure. Covered in scar tissue, the enlarged organ is nearly twice the normal size. Such alcoholic cardiomyopathy weakens the heart so that it is unable to pump blood adequately

Chronic Lymphocytic Leukemia -
As submitted by barelytherebutforeverhere:
Hey, I’m trying to raise awareness about CLL, a type of cancer that my Pop Pop was recently diagnosed with. If you and your followers could please take 2 seconds to check out my website it would mean the world to me <3 It’s the first post on my blog. I’m sorry it wouldn’t let me post the url in your ask :(
Any way that I can help! I checked it out myself and I’ve been planning on donating my hair as soon as it’s long enough. Thank you for the link and I hope your Pop Pop does well in chemo!
Check it out guys!

trioxide asked: what job do you want to get? :)
At this point, I’d say that my ideal job would be in a research facility as a biochemist, and then “retiring” at some point to become a professor. But, my ideas have changed quite a bit over the past year, so I wouldn’t count on it being solidified quite yet! But all of my ideas have been science-related, if not chemistry and biology specific :)
And I guess I’ll just partially use this post to apologize for my absence on this blog and the science tag recently. I’m sure I’ll be back by Wednesday or so of next week when I’m back home!
In the Sawmill Sink in Abaco, the water at a depth of 30 to 26 feet is pigmented by the bacteria. But the real danger lies in the hydrogen sulfide gas, which forces divers to hastily proceed through. Photo by Wes C. Skiles.

On December 4th, 1997, NASA launched Pathfinder, an unmanned mission to Mars which arrived seven months later on July 4th, 1997. The rover it carried, Sojourner, explored the red planet for a total of eighty days afterwards.
20 Things You Didn’t Know About Water
1 Water is everywhere—there are 332,500,000 cubic miles of it on the earth’s surface. But less than 1 percent of it is fresh and accessible, even when you include bottled water.
2 And “fresh” can be a relative term. Before 2009, federal regulators did not require water bottlers to remove E. coli.
3 Actually, E. coli doesn’t sound so bad. In 1999 the Natural Resources Defense Council found that one brand of spring water came from a well in an industrial parking lot near a hazardous waste dump.
4 Cheers! The new Water Recovery System on the International Space Station recycles 93 percent of astronauts’ perspiration and urine, turning it back into drinking water.
5 Kurdish villages in northern Iraq are using a portable version of the NASA system to purify water from streams and rivers, courtesy of the relief group Concern for Kids.
6 Ice is a lattice of tetrahedrally bonded molecules that contain a lot of empty space. That’s why it floats.
7 Even after ice melts, some of those tetrahedrons almost always remain, like tiny ice cubes 100 molecules wide. So every glass of water, no matter what its temperature, comes on the rocks.
8 You can make your own water by mixing hydrogen and oxygen in a container and adding a spark. Unfortunately, that is the formula that helped destroy the Hindenburg.
9 Scientists have a less explosive recipe for extracting energy from hydrogen and oxygen. Strip away electrons from some hydrogen molecules, add oxygen molecules with too many electrons, and bingo! You get an electric current. That’s what happens in a fuel cell.
10 Good gardeners know not to water plants during the day. Droplets clinging to the leaves can act as little magnifying glasses, focusing sunlight and causing the plants to burn.
11 Hair on your skin can hold water droplets too. A hairy leg may get sunburned more quickly than a shaved one.
12 Vicious cycle: Water in the stratosphere contributes to the current warming of the earth’s atmosphere. That in turn may increase the severity of tropical cyclones, which throw more water into the stratosphere. That’s the theory, anyway.
13 The slower rate of warming in the past decade might be due to a 10 percent drop in stratospheric water. Cause: unknown.
14 Although many doctors tell patients to drink eight glasses of water a day, there is no scientific evidence to support this advice.
15 The misinformation might have come from a 1945 report recommending that Americans consume about “1 milliliter of water for each calorie of food,” which amounts to 8 or 10 cups a day. But the report added that much of that water comes from food—a nuance many people apparently missed.
16 Call waterholics anonymous: Drinking significantly more water than is needed can cause “water intoxication” and lead to fatal cerebral and pulmonary edema. Amateur marathon runners have died this way.
17 Scientists at Oregon State University have identified vast reservoirs of water beneath the ocean floor. In fact, there may be more water under the oceans than in them.
18 Without water, ocean crust would not sink back into the earth’s mantle. There would be no plate tectonics, and our planet would probably be a lot like Venus: hellish and inert.
19 At the other end of the wetness scale, planet GJ 1214b, which orbits a red dwarf star, may be almost entirely water.
20 Recent evidence suggests that when the solar system formed 4.5 billion years ago, comets had liquid cores. If so, life may have started in a comet.

Illustrated here is a geologic map of Venus’s northern hemisphere, based off radar data from the Venera 15 and 16 orbiters, Pioneer Venus orbiter, and Earth-based radar telescopes. The colors indicate various features on the surface, such as plains in yellow and light green; mountains in purple, green and blue; and volcanoes in light red and pink.

Photo of the day: Golf resort vs. offshore wind farm
Donald Trump is hit on the head by a balloon-wielding bandit after visiting the Scottish Parliament to voice his opposition to a proposed offshore wind farm, which he says will spoil the view from his new $1.2 billion golf resort, slated to open in July in Aberdeenshire, Scotland.
“Scotland, if you pursue this policy of these monstrous turbines, Scotland will go broke,” Trump told the group. “They are ugly, they are noisy and they are dangerous. If Scotland does this, Scotland will be in serious trouble and will lose tourism to places like Ireland, and they are laughing at us.”
