Longevity is NOT genetic: Study of 400 million people reveals DNA has barely any impact on how long you will live
We used to think that genetics accounted for some 15-30 percent of life expectancy Genes do influence our risks of many health concerns and disease like cancer But a new study of Ancestry.com family tree data on 400 million people shows that lifespan is less inherited than we thought Scientists at the Genetics Society of America believe that lifespans that...

ATR inhibitors: destroying DNA
Analysis of an anti-cancer drug in clinical trials reveals a previously unknown effect on DNA that could contribute to its potency. Recent research aiming to establish biomarkers that could indicate the most effective course of therapy for a variety of cancers, which was conducted at the Perelman School of Medicine at the University of Pennsylvania (PA, USA)...

Pathogens may evade immune response with metal-free enzyme required for DNA replication
Some bacterial pathogens, including those that cause strep throat and pneumonia, are able to create the components necessary to replicate their DNA without the usually required metal ions. This process may allow infectious bacteria to replicate even when the host’s immune system sequesters iron and manganese ions in an attempt to slow pathogen replication. A new study, which appears in the journal Proceedings of the National...

Diseased heart muscle cells have abnormally shortened telomeres, researchers find
People with a form of heart disease called cardiomyopathy have abnormally short telomeres in heart muscle cells responsible for contraction, according to a new study by researchers at the Stanford University School of Medicine. Human chromosomes (grey) capped by telomeres (white). Credit: PD-NASA; PD-USGOV-NASA A telomere is a DNA sequence that serves as a protective cap on the ends...

CRISPR Study Shows Cas12a May Select DNA Target Sequences More Precisely Than Cas9
NEW YORK (GenomeWeb) – The Cas9 enzyme is known to have certain problems with binding to off-target DNA sequences, but for the most part, it is still considered to be the gold standard CRISPR enzyme for genome editing. However, in a new study in Molecular Cell today, researchers from the University of Texas at Austin...

Through the use of self-stopping enzymes, DNA synthesis has become faster, cheaper and better
Scientists at the Department of Energy’s Joint BioEnergy Institute (JBEI) based at the University of California, Berkeley (CA, USA) have developed a new way to synthesize DNA through the creative use of enzymes. The discovery, published in Nature Biotechnology, has the potential to revolutionize the fields of DNA synthesis and biological engineering. Until now, the...

Rise in Population Genomics: Local Government in India Will Use Blockchain to Secure Genetic Data
Blockchain will secure the DNA database for 50 million citizens in the eighth-largest state in India. The government of Andhra Pradesh signed a Memorandum of Understanding with a German genomics and precision medicine start-up, Shivom, which announced to start the pilot project soon. The move falls in line with a trend for governments turning to...
