Growing Cancer Cells & Coronal Mass Ejections Are Visually Similar

Image

 

Using solar and astronomical image processing techniques and mathematical theory we have developed novel image analysis techniques to track the growth of tumours and other cell-based structures, which can be crucial for advancements of therapeutics to treat diseases such as cancers.

The visual similarities between coronal mass ejections and the outward invasion of cells from a tumour spheroid are striking. This study aims to help us better understand changes in the tissue architecture which are associated with tumour growth.

Sperms Destroy Cancer Cells by Chemical Injection

Video

A study recently published by Haifeng et al. demonstrated the use of sperms guided by a magnetic source (so called spermbots) to deliver chemical injections to cervical cancer cells. A video of this demonstrations (see below) has been published by New Scientist.

Surprises at the Mariana backarc

Standard

The Mariana backarc, the same location of the deepest point on Earth, is where the thermal vents occur due to the spreading of two plates. In other words, the spreading apart of the sea floor results in a trench like the Mariana trench. At such backarcs, and the similar but not the same Mid-Ocean Ridges, “black smokers” form.

The following video is a fly-thru movie at the Mariana backarc in search for HydroThermal vents (second video).

Bacteria Breaking Antibiotic Environments

Standard

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

Standard

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.
