A study published in Science Advances reveals Bacterial Cellulose acts as a 'Band-Aid' for Plant healing.

About Bacterial Cellulose

• It is a natural polymer produced by certain types of bacteria.
• It has a unique structure with high purity, strength, and water-holding capacity.
• Application: Medicine (Wound dressing etc.), food (Packaging, Preservation etc.), cosmetics, agriculture etc. 

About Cellulose: 

• Cellulose is the most abundant extracellular structural polysaccharide in plants and most abundant biomolecule in the biosphere.
  • Humans cannot digest cellulose due to absence of enzyme cellulase. Cattle and termites can digest cellulose through symbiotic microorganisms in their gut that secrete cellulase.

A new study estimates the physical parameters of thermal & magnetic field structures of solar coronal holes.

About Solar Coronal Holes:

• Coronal holes appear as dark areas in the solar corona in extreme ultraviolet (EUV) & soft x-ray solar images. 
• They appear dark because they are cooler, less dense regions than the surrounding plasma. 
• These are regions of open, unipolar magnetic fields allowing high-speed solar wind to escape into space.
• Coronal holes can develop at any time and location on the Sun.
