Neural Cells derived from human embryonic stem cells
A cluster of neural cells were derived from human embryonic stem cells in the lab of UW-Madison stem cell researcher and neurodevelopmental biologist Su-Chun Zhang. The motor neurons are shown in red; neural fibers appear green and the blue specks indicate DNA in cell nuclei.

“Despite its outward appearance, the man o’ war is not a jellyfish but a siphonophore, which differs from jellyfish in that it is not actually a single creature, but a colonial organism made up of many minute individuals called zooids. Each of these zooids is highly specialized, and, although structurally similar to other solitary animals, they are attached to one another and physiologically integrated to the extent that they are incapable of independent survival.”
The White Sea Aliens - part 1- The arrival
The White Sea is an inlet of the Barents Sea, in the northwest coast of Russia. Its waters are cold and apparently devoid of life—until you do deep and discover an alien world full of colorful creatures that look from other planets.
The author of these photos works at the White Sea biological research station of the Moscow State University as a head of the diving department and as an underwater photographer. In the cold waters of the White Sea there are a lot of little and big creatures. Unfortunately naturalists’ profession is not popular nowadays so the guy takes such pictures more as a hobby.
of going to the ‘biology’ tag and seeing a bunch of stupid high schoolers whining about exams, or taking stupid fucking hipster pictures during their lab.
If your post has nothing to say about the subject of biology, in that there’s NOTHING I can learn from it, DON’T. FUCKING. TAG. IT. WITH. ‘BIOLOGY’.
That shit isn’t Biology, it’s you being stupid.
I swear, I have to page through 50 fucking things before I get ONE bit of useful information.
I will shank a bitch. O_O
Now watch me tag this with ‘biology’.
Thyroid Peroxidase, an enzyme produced in the Thyroid Gland, aids in the chemical reaction in which iodine is added to the protein Thyroglobulin. This process is what helps generate the Thyroid hormones T3 and T4 (Triiodothyronine and Thyroxine, respectively). These hormones are very important in regards to regulating growth within the body, aiding in brain development, and determining the rate in which energy is used within the body (metabolism).
I have something called Hashimoto’s Thyroiditis (or Hashimoto’s Disease). It’s an autoimmune disease where my own immune system kills my thyroid gland, eventually resulting in its death.
Genetics play a large role in thyroid disease, and a family history is somewhat common (my aunt has thyroid cancer).
I cannot be certain all of the symptoms I experience are caused solely from this, as I have other medical conditions with similar symptoms, but the list is as follows:
dry/flaky/ itchy skin
sensitivity to heat and cold
Luckily, there are synthetic hormones available (that I have to take every morning in the form of a small pill) that mimic the roles my natural ones aren’t fulfilling.
YAY SCIENCE! ^_^
