The Human Being

[ply-space-archived]

everyone who tries to explain the differences between bi, pan, ply, and omni ends up offending someone. they are missing the point. the goal isn't to have definitions that don't intersect and to be able to neatly sort people into categories based on their experiences. the definitions will always intersect and people's experiences will always escape definitions. the goal is to understand that anyone who identifies with one and not another has personal reasons to do so, and they are valid regardless. the goal is to realize that at the end of the day we're part of one community and many of our experiences overlap, while still respecting individual identities.

New 3D-Printable Material Developed That Mimics Biological Tissues

Biological tissues have evolved over millennia to be perfectly optimized for their specific functions. Take cartilage as an example. It’s a compliant, elastic tissue that’s soft enough to cushion joints, but strong enough to resist compression and withstand the substantial load bearing of our bodies: key for running, jumping, and our daily wear and tear.

Creating synthetic replacements that truly match the properties and behaviors of biological tissues hasn’t been easy. But University of Colorado Denver scientists, led by mechanical engineer professor Chris Yakacki, PhD, are the first to 3D print a complex, porous lattice structure using liquid crystal elastomers (LCEs) creating devices that can finally mimic cartilage and other biological tissues.

The CU Denver team, including professor Kai Yu, PhD, postdoctoral fellow Devesh Mistry, PhD, and doctoral student Nicholas Traugutt, as well as scientists from the Southern University of Science and Technology in China, reported its findings this week in the journal Advanced Materials.

If we didn't have ears, we wouldn't know about sound. So it's possible there's other sensations we don't know about because we don't have organs to detect them.

The Shortest People In History

Alcohol breath is not from the stomach, rather it’s from the ethanol diffusing out of the blood in the lungs. Eating food, chewing gum, or vomiting won’t help mask how much alcohol is in your system if you’re breathalyzed.

The Neuroscience of Free Will: Everything You Need To Know

Who are you and how did you become interested in free will? How do neuroscientists study free will? Does science approves "My brain made me do it" concept?

Yeah, that sounds like crap, but here are three sources to prove we’re not full of shit! :-D

A human being needs certain things to survive and grow. At the very least the basic needs to survive. Having just the basic needs is not enough, there are other things that are essential to growth and leading a purposeful and happy life.

 Humans being sentient and self-aware need love and belonging, self esteem and self-actualisation in order to be happy and make others happy to. But first in order to that they need to be safe and secure and have their physiological needs met.

 Not all humans are lucky enough to attain all the things they need and struggle with what they have attained. That is sad but true. There is still hope in the future that humanity will reach a point of enlightenment where every human being leads a purposeful and fulfilling life.

Parathyroid

Parathyroid glands are four small glands of the endocrine system which regulate calcium and phosphate. They are located in the neck behind the thyroid.

Parathyroids are NOT related to the thyroid (just neighbours). however they share a similar blood supply, venous drainage, and lymphatic drainage.

You can easily live with one (or even ½) parathyroid gland.

Function

Parathyroid glands control calcium and phosphate levels by producing Parathyroid Hormone (PTH). 

Calcium:

PTH increases blood calcium levels by directly stimulating osteoblasts and thereby indirectly stimulating osteoclasts (through RANK/RANKL mechanism) to break down bone and release calcium.

 PTH increases gastrointestinal calcium absorption by activating vitamin D, and promotes calcium conservation (reabsorption) by the kidneys.

Phosphate:

PTH is the major regulator of serum phosphate concentrations via actions on the kidney. 

Inhibites of proximal tubular reabsorption of phosphorus. 

Activates vitamin D - absorption (intestinal) of Phosphate is increased.

Hypoparathyroidism

Decreased function of the parathyroid glands with underproduction of parathyroid hormone. 

Lead to low levels of calcium in the blood, often causing cramping and twitching of muscles or tetany (involuntary muscle contraction), and other symptoms. 

Can be inherited, but it is also encountered after thyroid or parathyroid gland surgery, and it can be caused by immune system-related damage 

The treatment of hypoparathyroidism is limited as there is no exact form of the hormone that can be administered as replacement. 

Tumours can form on the parathyroid glands, but they are usually benign adenomas.
