Anhydrobiosis without trehalose in bdelloid rotifers

sciencewithevie

Anhydrobiosis without trehalose in bdelloid rotifers SUMMARY: There are many types of organisms that can dry out, rehydrate, and then go about their lives with no problems. Many of the larger ones use trehalose or sucrose as an antifreeze. Bdelloid rotifers (tiny microscopic animals) do not. This study looked at the carbohydrate content in desiccated… Continue reading Anhydrobiosis without trehalose in bdelloid rotifers

Enzyme Catalysis To Power Micro/Nanomachines

sciencewithevie

Enzyme Catalysis To Power Micro/Nanomachines SUMMARY: Is it possible to make nanomachines out of enzymes? This review looks at the ways we can harness enzymes to self-propel or use them as tiny machines. Doing so would have many implications in nanotechnology and drug delivery. There were a few ways to use enzymes. First, there was… Continue reading Enzyme Catalysis To Power Micro/Nanomachines

Chloroplast Division

sciencewithevie

Chloroplast Division SUMMARY: Chloroplast division in plants is still a fairly unknown topic when it comes to specific cellular/molecular mechanisms. This paper describes, step by step, all the proteins and enzymes involved in helping chloroplasts divide (FtsZ, Min system, ARC6, etc.) It also compares the division of chloroplasts to binary fission in various prokaryotes (FtsZ… Continue reading Chloroplast Division

Field and lab conditions alter microbial enzyme and biomass dynamics

sciencewithevie

Field and lab conditions alter microbial enzyme and biomass dynamics driving decomposition of the same leaf litter SUMMARY: This study looked at the rate of decay between litter in lab conditions and natural conditions. They used fallen leaves from dogwood trees, oak trees, maple trees, and maple-oak tree mix. Results showed quite a difference in… Continue reading Field and lab conditions alter microbial enzyme and biomass dynamics
