Bacteria Breaking Antibiotic Environments


The video below by researchers at the Harvard Medical School and Technion–Israel Institute of Technology shows bacteria break zones of ever increasing concentrations of antibiotics hence demonstrates how bacteria becomes “impervious to drugs”. They are able to

In a creative stroke inspired by Hollywood wizardry, scientists from Harvard Medical School and Technion-Israel Institute of Technology have designed a simple way to observe how bacteria move as they become impervious to drugs. [2]

TEDMED – One more reason to get a good night’s sleep


Research paper: Sleep Drives Metabolite Clearance from the Adult Brain, DOI: 10.1126/science.1241224

Important points:

  • Brain has no lymphatic system to clean it
  • During sleep brain cells seem to shrink
  • Cerebrospinal fluid (CSF) acts as a detoxing agent removing toxins built up while the brain is conscious.
  • CSF influx only happens during sleep. It is inhibited during wakefulness.

and we discovered that at the same time when the brain goes to sleep, the brain cells themselves seem to shrink, opening up spaces in between them, allowing [cerebrospinal fluid – CSF] fluid to rush through and allowing waste to be cleared out.

But our most surprising finding was that all of this, everything I just told you about, with all this fluid rushing through the brain, it’s only happening in the sleeping brain.

ASR syndrome scales and (brain) connectivity associations


I found an interesting poster on brain connectivity associations of the ASR syndrome categorized by scales (depressed, stomach complaint, withdrawn, attention problems, thought problems, tobacco use, etc…) presented during the 2014 meeting of the Society of Biological Psychiatry (SOBP 2014) and wanted to share the graphic (2nd image) with you.
