Robots are an important type of molecular machine capable of automatically carrying out complex nanomechanical tasks. DNA molecules are excellent materials for building molecular robots as their geometric, thermodynamic, and … Continue Reading First autonomous cargo-sorting DNA nanobot developed.
Telomeres are our own personal inbuilt clock found at the end of chromosomes dictating how and when we age, with these protective caps ensuring no damage comes to the DNA … Continue Reading Researchers identify previously unknown telomere-specific protein.
A strand of DNA is a very long, narrow string, just a few nanometers across. Single-molecule orientation measurements provide unparalleled insight into a multitude of biological and polymeric systems. Single-molecule … Continue Reading New imaging technique reveals unprecedented nanoscale details about DNA.
In 1953 Watson and Crick first published the discovery of the double helix structure of the DNA. They were able to visualize the DNA structure by means of X-Ray diffraction. … Continue Reading Researchers image and count nucleosomes in the human genome for the first time ever.
Transfer RNAs (tRNAs) are ancient workhorse molecules and part of the cellular process that creates the proteins, critical building blocks of life that keep a cell running smoothly. A new … Continue Reading Researchers find human genomic loci coding for tRNAs is double what is currently known.
Genetic information is stored in DNA, tiny strands of nucleic acid that contain instructions for the functioning of the human body. To express this genetic data, our DNA is copied … Continue Reading Scientists find how mysterious ‘circular RNA’ is formed, claim muscular dystrophy link.
A new 4,000 person study from the Washington University School of Medicine shows that schizophrenia isn’t a single disease but a group of eight genetically distinct disorders, each with its … Continue Reading Schizophrenia not a single disease but multiple genetically distinct disorders.
Over the years researchers have made tremendous strides in the understanding and treatment of cancer by searching genomes for links between genetic alterations and disease. Most of those studies have … Continue Reading Penn team mine specific ovarian cancer oncogene in ‘junk DNA’.
RNA is one of the most primitive molecules associated with life that has awakened most interest over the last decade; a sister molecule to cellular DNA from which it originates … Continue Reading CNIO experts discover the genomic origin of telomere protectors.
A new study finds a wide range of epigenetic changes, alterations in DNA across the genome that may be related to key environmental exposures, in children with Crohn’s disease (CD), … Continue Reading Study shows epigenetic changes in children with Crohn’s Disease.
The U.S. Food and Drug Administration has approved Cologuard, the first stool-based colorectal screening test that detects the presence of red blood cells and DNA mutations that may indicate the … Continue Reading FDA approves world’s first non-invasive DNA screening test for colorectal cancer.
Physicians at Johns Hopkins have developed blood and saliva tests that help accurately predict recurrences of HPV-linked oral cancers in a substantial number of patients. The tests screen for DNA … Continue Reading Blood and saliva tests predict return of HPV-linked oral cancers.
While developing a new cancer drug, researchers at The Wistar Institute discovered that mice lacking a specific protein live longer lives with fewer age-related illnesses. The mice, which lack the … Continue Reading ‘Rewired’ mice show signs of longer lives with fewer age-related illnesses.
Johns Hopkins researchers say they have discovered a chemical alteration in a single human gene linked to stress reactions that, if confirmed in larger studies, could give doctors a simple … Continue Reading A blood test for suicide?
Millions of people in the United States have a circulatory problem of the legs called peripheral vascular disease. It can be painful and may even require surgery in serious cases. … Continue Reading Scientists discover genetic switch that can prevent peripheral vascular disease in mice.
Using data from over 18,000 patients, scientists have identified more than two dozen genetic risk factors involved in Parkinson’s disease, including six that had not been previously reported. Unravelling the … Continue Reading NIH scientists find 6 new genetic risk factors for Parkinson’s.
