What if your heart could beat perfectly until your last days? Theoretically, that’s now possible.
Scientists at Washington University and University of Illinois have combined electrical engineering, 3D printing, and biology to create a custom thin mesh of electrodes that lays over the heart to correct improper cardiac impulses, ensuring the heart beats the right way every time.
This has huge implications for patients who suffer from myocardial infarctions, arrhythmias, and more. Click here to read more.
Science is pretty cool.
After running a hose down to the highway, a firefighter jumps down on to the on-ramp that leads from South Washington Street on to #I-25. One person was killed and 20 people were taken to three hospitals with injuries Saturday morning in a giant pileup on north bound Interstate 25 as a band of heavy snow moved through Denver.

I think one of my new coworkers was stuck in this :/ Poor guy, it’s his first week in state
Raynaud’s phenomenon is a condition resulting from poor circulation in the extremities. In a person with Raynaud’s phenomenon, when his or her skin is exposed to cold or the person becomes emotionally upset, the blood vessels under the skin tighten and the blood flow slows. This is called vasospasm. Hands and feet have fewer large blood vessels and, therefore, when a vasospasm occurs, it is harder for the blood to keep flowing and these areas may turn blue because less oxygen is reaching the skin. The skin will also feel cold because less blood is reaching the skin to keep it warm. While attacks of vasospasm may last from minutes to hours, only rarely do they cause severe tissue damage.
I have that. It’s fun to watch.
- mostly viral (parainfluenza, RSV) causes mucosal inflammation and increased airway secretions
- risk of subglottic oedema can lead to critical narrowing of airway
- peak incidence 2 years old, esp in autumn/winter
- initially coryzal symptoms with fever
- leading to barking cough, stridor, hoarseness
- signs of respiratory distress e.g. tachypnoea, recessions, tracheal tug
- Management - oxygen, nebulised adrenaline, oral + nebulised steroids, few may require intubation
First part of my Medic ED rotation, I was dubbed “Croup Croup-ba-doop” for two reasons:
1) seemed like for two solid months if a kid came into the ED while I was there, the kid was sure to have croup
2) that song is mah JAM!
An analysis of ancient oral microbiome ecology and function, led by the University of Zürich, the University of Copenhagen, and the University of York has discovered a microbiome preserved on the teeth of skeletons around 1,000 years old. The dental calculus preserves bacteria and microscopic particles of food on the surfaces of teeth, effectively creating a mineral tomb for microbiomes.
The research published in Nature Genetics reveals that unlike bone which rapidly loses much of its molecular information when buried, calculus grows slowly in the mouth and enters the soil in a much more stable state helping it to preserve biomolecules. This enabled the researchers, led by Dr Christina Warinner, to analyse ancient DNA that was not compromised by the burial environment.
What do you think peeps? Anybody with a similar story to help her out?
Signal boost - can anyone help?
