Scientists Use Exotic DNA To Help Create “Climate-Proof” Crops

Posted by in categories: biotech/medical, food, genetics

The incorporation of exotic DNA

DNA, or deoxyribonucleic acid, is a molecule composed of two long strands of nucleotides that coil around each other to form a double helix. It is the hereditary material in humans and almost all other organisms that carries genetic instructions for development, functioning, growth, and reproduction. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Genetic engineering sheds light on ancient evolutionary questions

Posted by in categories: bioengineering, climatology, genetics, sustainability

Cyanobacteria are single-celled organisms that derive energy from light, using photosynthesis to convert atmospheric carbon dioxide (CO2) and liquid water (H2O) into breathable oxygen and the carbon-based molecules like proteins that make up their cells. Cyanobacteria were the first organisms to perform photosynthesis in the history of Earth, and were responsible for flooding the early Earth with oxygen, thus significantly influencing how life evolved.

Geological measurements suggest that the atmosphere of the early Earth—over three billion years ago—was likely rich in CO2, far higher than current levels caused by , meaning that ancient had plenty to “eat.”

But over Earth’s multi-billion-year history, atmospheric CO2 concentrations have decreased, and so to survive, these bacteria needed to evolve new strategies to extract CO2. Modern cyanobacteria thus look quite different from their ancient ancestors, and possess a complex, fragile set of structures called a CO2-concentrating mechanism (CCM) to compensate for lower concentrations of CO2.

Synthetic biology has the potential to upend existing paradigms of adeno-associated virus (AAV) production, helping to reduce the high costs of gene therapy and thus make it more accessible, according to a recent paper.

“Having focused on genetic advancements in ancient DNA for my entire career and as the first to fully sequence the Dodo’s genome, I am thrilled to collaborate with Colossal and the people of Mauritius on the de-extinction and eventual re-wilding of the Dodo. I particularly look forward to furthering genetic rescue tools focused on birds and avian conservation,” Shapiro added.

A “Missing Link” — Researchers Shed Light on the Origin of Complex Life Forms

Posted by in categories: biological, genetics

What led to the emergence of complex organisms on Earth? It’s a significant unanswered question in biology. Researchers from Christa Schleper’s team at the University of Vienna and Martin Pilhofer’s team at ETH Zurich have taken a step towards resolving it. The scientists succeeded in cultivating a special archaeon and characterizing it more precisely using microscopic methods.

This member of the Asgard archaea exhibits unique cellular characteristics and may represent an evolutionary “missing link” to more complex life forms such as animals and plants. The study was recently published in the journal Nature.

All life forms on earth are divided into three major domains: eukaryotes, bacteria and archaea. Eukaryotes include the groups of animals, plants and fungi. Their cells are usually much larger and, at first glance, more complex than the cells of bacteria and archaea. The genetic material of eukaryotes, for example, is packaged in a cell nucleus and the cells also have a large number of other compartments. Cell shape and transport within the eukaryotic cell are also based on an extensive cytoskeleton. But how did the evolutionary leap to such complex eukaryotic cells come about?

Scientists have identified six rules for maintaining memory and reason in old age

Posted by in categories: biotech/medical, genetics, neuroscience

Chinese scientists in a 10-year study found that people who adhered to the special six rules, the risk of dementia decreased by 90%. Even with a genetic predisposition to Alzheimer’s disease. The study involved 29 thousand people over 60 years of age, who were divided into three groups.
