DNA reprogramming in human germ cells observed for first time

germline-epigenomic-development

Led by the University of Cambridge a team of researchers have, for the first time, described in humans how the epigenome – the suite of molecules attached to our DNA that switch our genes on and off – is comprehensively erased in early primordial germ cells prior to the generation of egg and sperm.   Continue reading… “DNA reprogramming in human germ cells observed for first time”

Man-made artificial DNA strands that mimic deadly diseases such as the flu, Ebola, cancer, and HIV have recently been created by scientists.  Researchers are claiming that the treatments could be the key to defeating these killer diseases.  Human trials have already begun and results are with researchers saying the results are promising.   Continue reading… “Man-made DNA that can mimic killer diseases, injecting them into patients create immunity”

Creating a bacterial kill switch using genome engineering

5613657007_7af10f9985_z

Researchers announced in 2011 that they had reprogrammed the genome of the bacteria E. coli so that one of DNA’s methods of encoding information went unused.  While a technological breakthrough, the scientists didn’t do anything with the new bit of genetic code.  Now only a few years later, two different groups have taken this technological tour-de-force, and are using it in the same way:  creating genetically modified organisms that may never be able to escape into the wild.

Scientists discover greater rates of mitochondrial mutations in children born to older mothers

mitochondria-maternal-age

A  normal mitochondria (left) contain distinctive folds known as cristae, but these folds are lost in damaged or dysfunctional mitochondria (right).

A team of Penn State scientists have discovered a “maternal age effect” that could be used to predict the accumulation of mitochondrial DNA mutations in maternal egg cells — and the transmission of these mutations to children — could provide valuable insights for genetic counseling. These mutations cause more than 200 diseases and contribute to others such as diabetes, cancer, Parkinson’s disease, and Alzheimer’s disease.

It isn’t easy to brew your own beer. It’s also hard to brew a good batch of beer, and even harder to duplicate that batch to drink later on. And it is near impossible to simplifying the process so that it’s as effortless as baking cookies because of all the factors involved with the brewing process, including fermentation, location, temperature, and of course the availability of equipment itself.
