CRISPR Toolbox Expanded by Protein That Cuts RNA in Two Distinct Ways

Sep. 27, 2016 — Researchers have expanded the role of the newly discovered CRISPR protein C2c2 that targets RNA instead of DNA. C2c2 has been described as an RNA-guided RNA-cutting enzyme; however, a full ... read more

New Switch Decides Between Genome Repair, Death of Cells

Sep. 27, 2016 — The genetic information of every cell is encoded in the sequence of the DNA double helix. Double strand breaks in the DNA, which can be induced by radiation, are a dangerous threat to the cells, and ... read more

Good Cells Turn Bad: Supportive Brain Cells Which 'Go-Rouge' and Become Destructive Could Hold the Key to MND

Sep. 26, 2016 — A pioneering study has revealed a cell which usually supports motor neuron function becomes destructive and actually causes cell death in patients with Motor Neuron ... read more

Sep. 26, 2016 — To fill in the blanks on mitochondria, researchers deleted 174 genes, one by one, in yeast. They then subjected the yeast to high-intensity mass spectrometry to measure unprecedented detail on ... read more

Sep. 22, 2016 — With the help of two young patients with a unique neurological disorder, scientists have discovered that a gene called PIEZO2 controls specific aspects of human touch and proprioception, a ... read more

Sep. 22, 2016 — Mercury is a potent neurotoxin present in our daily lives and our body can accumulate it over the years. Food consumption, such as fish and rice, is the most common source of mercury exposure. ... read more

New Insights Into Potent Cancer Tumor Suppressor Gene

Sep. 22, 2016 — TP53 is one of the most potent genes in the human genome at preventing cancer and hence is termed a tumor suppressor gene, explain researchers. The TP53 gene has even greater anti-cancer activity ... read more

Sep. 22, 2016 — The DNA of young people is regulated to express the right genes at the right time. With the passing of years, the regulation of the DNA gradually gets disrupted, which is an important cause of aging. ... read more

Sep. 21, 2016 — Smoking leaves its "footprint" on the human genome in the form of DNA methylation, a process by which cells control gene activity, according to new research. Even after someone stops ... read more

Biological 'Dark Matter' Molecule Plays Surprise Role in Heart Failure

Sep. 21, 2016 — A molecule that appears to play a key role in the development of heart failure has been discovered by researchers. The scientists found that blocking the molecule, known as chaer, in animal studies ... read more

Computers Learn to Spot Deadly Bacteria

Sep. 21, 2016 — Machine learning can predict strains of bacteria likely to cause food poisoning outbreaks, research has found. The study -- which focused on harmful strains of E. coli bacteria -- could help public ... read more
