Germany unveils zero-emissions train that only emits steam

Germany will deploy world’s first zero-emission passenger train to be powered by hydrogen and lithium ion batteries, made by French company Alstom.  Here is a 3 min video of the train ► https://youtu.be/O3bUE9uHkqM. The train only emits excess steam into the atmosphere, and provides an alternative to Germany’s 4,000 diesel trains that emit a lot of carcinogenic chemicals, besides CO2.  Lower Saxony has already ordered 14 of them, and more are likely to be seen around the country.  Norway, Netherlands, Denmark are also interested.  The hydrogen fuel tank on the roof of the train.

What are some of your favourite med school mnemonics? (5 weeks out from finals haha)

I was a big fan of the shortcut way to draw the brachial plexus, though I don’t remember it perfectly now. Unfortunately I remember more mnemonics than what they’re supposed to stand for. 

Other faves include:

  • Learn one. The other one’s the other one. - Goljan’s wise advice on learning the difference between 2 things. This is how I distinguish pemphigus and pemphigoid. 
  • the R-rated version of the cranial nerves. I’ll just abbreviate OOOTTAFVGVAH. I still run through that one. 
  • Some Say Marry Money But My Brother Says Big Boobs Matter More (remembering which cranial nerves are sensory, motor, or both)
  • I remember on renal drawing Hydrogen and potassium ions on a seesaw to remember how they moved in relationship to each other
  • There was definitely a weird one to remember the glycogen storage diseases, but I’ve never had to use that one so I’ve forgotten.
  • SpIN and SnOUT - for specificity and sensitivity, which rules in and which rules out
  • SIG E CAPS - symptoms of depression - Sleep disturbance, loss of Interest, Guilt, loss of Energy, poor Concentration, Anhedonia, Psychomotor retardation, Suicidality
  • MUDPILES - things that cause anion gap metabolic acidosis
  • DUMBBELS - cholinergic overdose symptoms - Diarrhea, Urination, Miosis, Bronchorrhea, Bradycardia, Emesis, Lacrimation, Sweating/Salivation
  • DIAPPERS - causes of urinary incontinence - Delirium, Infection, Atrophic Vaginitis, Pharmaceuticals, Psych, Excessive urine output, Reduced mobility, Stool impaction
  • Dry as a bone, hot as hades, blind as a bat, red as a beet, mad as a hatter - effects of anticholinergic drugs
  • wet, wacky, wobbly - symptoms of normal pressure hydrocephalus
  • bones, groans, stones, and psychic moans- symptoms of hypercalcemia
  • VEAL CHOP - fetal monitoring (put the words on top of each other)- Variable = Cord compression; Early Decel = Head compression; Acceleration = O2; Late Decel = Placental insufficiency
  • social history on kids and teenagers: HEADDSSS - Home, Education, Activities, Drugs, Depression, Safety, Sex, Suicide

H2O = two hydrogen ions bonded* to an oxygen ion

*bond = “polar covalent”: the molecule has opposite charges on opposite ends; this is due to the electronegativity difference between the H’s and O, causing the H’s to have partial negative charges and the O to have a partial positive one; strong bond that keeps the water molecule together

H2O molecules bond to each other by “hydrogen bonding”: these are weaker bonds that are able to be broken and reformed frequently; this allows water its many emergent properties and to be the key to life

Four emergent properties:

1)      Cohesion/Adhesion- This is the ability of water molecules to stick to one another due to hydrogen bonding as well as to other surfaces, respectively. This is what allows transpiration up the plant xylem and out the leaves to occur (this is also due to the difference in water concentrations between inside the plant and in the atmosphere, as water wants to go from a high concentration to a low concentration). Also, surface tension is considered a subtopic of this property.

2)      Moderation of Temperature- Due to water’s high specific heat, it is able to absorb heat from the environment (breaking bonds) or release heat to it (forming bonds), without more than a slight change in its own temperature. This allows water to regulate to temperature of the environment around it and to make sure it is habitable enough for life. Water also has a high heat of vaporization. This results in “evaporative cooling”: as a surface is heated (heat is absorbed), the hydrogen bonds between water molecules break, and water changes from its liquid form to a gas, and is evaporated. This allows water to stabilize the temperatures of organisms and bodies of water.

3)      Expansion upon Freezing- When water freezes and changes to its solid form, the H2O molecules form a crystal lattice, where the hydrogen bonds keep each water molecule a certain distance away from each other. Due to this further apart spacing, ice is less dense than liquid water. Therefore, ice floats on top of liquid water. This allows ice to insulate what is below it, and helps regulate life.

4)      Versatility as a Solvent- Due to the partial pos. and partial neg. charges within an H2O molecule, when a solute is introduced into water, as long as that solute has charged ions, the H’s and O’s will be attracted to the oppositely charged ions, creating a hydration shell around the ions and pulling them away from the solute’s molecules, dissolving it (WATER IS PRETTY CLOSE TO A UNIVERSAL SOLVENT.)


An “acid” is any substance that increases the hydrogen ion concentration of a solution.

A “base” is any substance that reduces the hydrogen ion concentration of a solution.

pH = “percent (%) hydrogen”

[H+] and [OH-] have an inverse relationship. This means as one goes up in concentration, the other goes down. Their relationship always has a constant of 10 ^ -14.)

(In a neutral solution, pH is 7, which means [H+] = 10 ^ 7, and [OH-] = 10 ^ 7.)

*Know how to do a Mol equation/set-up*


Carbon can create up to four bonds with many different elements due to its “tetravalence” (has 4 valence electrons, and needs 4 more)

Ability to create long chains, often with hydrogen, resulting in organic molecules

Despite some organic molecules being isomers (same molecular formula), the variation in their carbon skeletons (brancing, double bonds, etc.) is what makes them completely different molecules.


Monomers are the “building blocks” of macromolecules, which, when linked together, create polymers.

Monomers are bonded together using “dehydration synthesis” (the removal of water molecules), and broken apart by “hydrolysis” (the addition of water molecules).


Carbohydrates are sugars that provide fiber and a quick source of energy for your body. The monomer of carbohydrates is called a monosaccharide. Glucose is most common monosaccharide.

The type of links within carbohydrates are called “glycosidic linkages”. Two monosaccharides linked together creates a disaccharide. For example, two glucose molecules bonded together would create maltose.

Many monosaccharides linked together creates a polysaccharide. In aqueous solutions they form rings.

Carbohydrates are used for many different purposes, such as energy storage in plants (starch) and animals (glycogen), as well as for structure within plants (cellulose, forms cell wall) and animals (chitin, forms exoskeletons).

Carbohydrates contain a carbonyl group

Carbs contain “alpha” or “beta” links. We are unable to digest beta links.


Lipids are not considered polymers because they are made up of a few monomers they are not made up of many. Usually lipids consist of a glycerol and three fatty acids (triglyceride). There are three types of lipids: fats, phospholipids, and steroids, but they all have one thing in common: they are hydrophobic. This is due to them being nonpolar and having no charge (fatty acids are basically really long chains of hydrogen and carbon with no charge).

The types of links within lipids are called “ester linkages”.

Saturated fats have a straight molecule and are solid at room temperature. These are bad for you, such as butter.

Unsaturated fats are “kinked” due to a carbon double bond and are liquid at room temperature. These are good for you, such as different types of oils.

Phospholipids contain a hydrophilic head (this is due to it actually having a charge due to its phosphate group’s neg. charge) and a hydrophobic tail. They make up the cell membrane of animal cells.

Steroids are made up of 4 carbon rings. One common type of steroid is cholesterol.


Amino acids are the building blocks, made from the ribosomes of cells. They can either be nonpolar, polar, electrically charged, or etc. There are 20 different amino acids in existence, but they can make up countless proteins.

Amino acids consist of an alpha carbon, a hydrogen, an R group/side chain, a carboxyl group (COOH), and an amino group (N3H+). The “R” group is the variable that makes the specific amino acid unique. All amino acids are distinguishable by their “N-C-C” backbone.

The types of bonds present between amino acids are called peptide bonds, and the polymers of amino acids are called “polypeptides” (proteins).

Amino acids sequences are controlled by DNA/genetics. Even one amino acid being out of place can cause serious issues.

There are 4 levels of conformation to creating a protein. CONFORMATION = STRUCTURE.

Primary structure consists of the unique amino acid sequence. Secondary structure is the “backbone” of a protein, where the curves and folding of polypeptide chains are created through the attraction of hydrogen bonding. Tertiary structure by the interactions (Ex: types of bonds) between the “R” groups. Quaternary structure is the creation of a macromolecule through two or more polypeptides.

Some examples of quaternary structures are collagen (found in hair) and hemoglobin (found in the blood, in RBC’s).

Nucleic acids

Monomers are called nucleotides.

They make up your genes.

There are two types, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

They consist of a phosphate group, a pentose sugar, and a nitrogenous base.

5 things you didn’t know about…metal organic frameworks

Credit: CSIRO

1. First developed in the 1990s, MOFs are crystalline hybrid materials created from both organic and inorganic molecules via molecular self-assembly.

2. They are formed from linkers – long chains, typically of carbon and hydrogen oxides decorated with nitrogen atoms – and positively charged metal ions, which form nodes that bind the arms of the linkers together.

3. One pea-sized gram of MOF material can host the equivalent surface area of 40 tennis courts, and because most of their bulk is empty space, MOFs are also extremely light.

4. USA, chemist Professor Omar Yaghi has pioneered research into MOFs. He authored the first published report of a MOF in 1999 and estimates that his lab alone has created in excess of 1,000 different MOF structures since.

5. One of the most promising features of MOFs is that they are applicable to carbon capture and storage (CCS). In a study by Pike Research (now part of Navigant), USA, they are expected to reach a potential market value of US$221bln by 2030.
