Hello, name is Nereid Castillo. Uh, this is kinda a reference blog; don't expect much. Mostly medical stuff, but also a bit of astronomy and biology too.
Human Societies Starting to Resemble Ant Colonies
The similarities offer a look at just how ever-growing human societies could collapse.
The human population is growing at such a staggering rate that we are organizing ourselves more like ant supercolonies, with new research finding that we have more in common now with some ants than we do with our closest living animal kingdom relatives.
The new study, published in the journal Behavioral Ecology, points out that both humans and ants (termites, too) live in societies that may consist of up to a million plus members.

Scientists by Tomas Muller
With the intention of depicting science as the true adventure and worthy pursuit it is, Tomas created this series as a promotion for the Charles University’s Faculty of Science in Prague. These Titans of ginormous stature are each a visual representation of an area of science: biology, geography, chemistry, and geology. I’ll let you figure out which Titan is which, after all, you should already know this stuff. But before you ask: the Titan representing the science of pizzamaking was, sadly, omitted.
Hi solidgrey, our 2000th follower! <3 Might I add that your blog is awesome, and this is pretty fucking cool.
this gives me an art boner.
Dis pretty.

Melanoma
Melanoma is a malignant tumor of melanocytes. Melanocytes are cells that produce the dark pigment, melanin, which is responsible for the color of skin. They predominantly occur in skin, but are also found in other parts of the body, including the bowel and the eye (see uveal melanoma). Melanoma can originate in any part of the body that contains melanocytes. Melanoma is less common than other skin cancers, however, it is much more dangerous if it is not found early. It causes the majority (75%) of deaths related to skin cancer. Worldwide, doctors diagnose about 160,000 new cases of melanoma yearly.
Unusual moles that may indicate melanoma:
Characteristics of unusual moles that may indicate melanomas or other skin cancers follow the A-B-C-D-E guide developed by the American Academy of Dermatology:
- A is for asymmetrical shape. Look for moles with irregular shapes, such as two very different-looking halves.
- B is for irregular border. Look for moles with irregular, notched or scalloped borders — characteristics of melanomas.
- C is for changes in color. Look for growths that have many colors or an uneven distribution of color.
- D is for diameter. Look for new growth in amole larger than about 1/4 inch (6 millimeters).
- E is for evolving. Look for changes over time, such as a mole that grows in size or that changes color or shape. Moles may also evolve to develop new signs and symptoms, such as new itchiness or bleeding.

Flapjack (or pancake) devilfish (or octopus) are rarely seen swimming in open water, preferring to flatten themselves on the bottom, when the reason for their name becomes apparent.
it’s a good thing I contribute to this blog because otherwise my personal tumblr would be constantly inundated with biology posts.

and this is why studying larval fish is hard, guys. They’re tiny and translucent and hella hard to find in seaweed.
