Newfound groups of bacteria are mixing up the tree of life
University of California, Berkeley, scientists have identified more than 35 new groups of bacteria, clarifying a mysterious branch of the tree of life that has been hazy because these microbes can't be reared ...
New evidence emerges on the origins of life
In the beginning, there were simple chemicals. And they produced amino acids that eventually became the proteins necessary to create single cells. And the single cells became plants and animals. Recent research ...
New mitochondrially-derived peptides show what they can do
Genetic switch regulates transcription and replication in human mitochondria
Scientists re-create what may be life's first spark
Scientists in a lab used a powerful laser to re-create what might have been the original spark of life on Earth.
World's first artificial enzymes created using synthetic biology
(Phys.org)—Medical Research Council (MRC) scientists have created the world's first enzymes made from artificial genetic material. Their synthetic enzymes, which are made from molecules that do not occur ...
Scientists make enzyme that could help explain origins of life
Mimicking natural evolution in a test tube, scientists at The Scripps Research Institute (TSRI) have devised an enzyme with a unique property that might have been crucial to the origin of life on Earth.
Scientists resurrect 700-year-old viruses
Human cells' protein factory has an alternate operating manual
Working with a gene that plays a critical role in HIV infection, University of Maryland researchers have discovered that some human genes have an alternate set of operating instructions written into their ...
RNA carried by new nanoparticles can silence genes in many organs, could be deployed to treat cancer
RNA interference (RNAi), a technique that can turn off specific genes inside living cells, holds great potential for treating many diseases caused by malfunctioning genes. However, it has been difficult for ...
Researchers discover new mechanism of DNA repair
The DNA molecule is chemically unstable giving rise to DNA lesions of different nature. That is why DNA damage detection, signaling and repair, collectively known as the DNA damage response, are needed.
Viral protein in their sights: Advanced imaging reveals key structure of Ebola and other RNA viruses
Viruses need us. In order to multiply, viruses have to invade a host cell and copy their genetic information. To do so, viruses encode their own replication machinery or components that subvert the host replication ...
The hidden treasure in RNA-seq
Michael Stadler and his team at the Friedrich Miescher institute for Biomedical Research (FMI) have developed a novel computational approach to analyze RNA-seq data. By comparing intronic and exonic RNA reads, ...
New tech could find tiny RNA cancer beacons in blood
Cancerous tumors cast off tiny telltale genetic molecules known as microRNAs and University of Michigan researchers have come up with an efficient way to detect them in blood.
