Five New Genetic Variants Linked to Brain Cancer

Oct. 1, 2015 — The biggest ever study of DNA from people with glioma -- the most common form of brain cancer -- has discovered five new genetic variants associated with the disease. Researchers said their findings ... read more

New DNA Stain Lights Up Living Cells

Oct. 1, 2015 — A new DNA stain that can be used to image living cells has been created by scientists. The new stain works by binding to a part of the DNA helix known as the "minor groove." Once bound, it ... read more

Real-Time Analysis of Metabolic Products

Oct. 1, 2015 — A method that, for the first time, makes it possible to measure concentration changes of several hundred metabolic products simultaneously and almost in real time has been developed by researchers. ... read more

Oct. 1, 2015 — Scientists have discovered that reactivation of ancient viral genes embedded in the human genome may cause the destruction of neurons in some forms of amyotrophic lateral sclerosis (ALS). The results ... read more

Genes That Protect African Children from Developing Malaria Identified

Oct. 1, 2015 — Variations in DNA at a specific location (or 'locus') on the genome that protect African children from developing severe malaria, in some cases nearly halving a child's chance of ... read more

Oct. 1, 2015 — A team of researchers has refined a mathematical model that simulates the impact of genetic mutations on cell division -- a step that could provide insight into errors that produce and sustain ... read more

Proof-of-Concept for Low-Cost Drug Made in Lettuce

Oct. 1, 2015 — Scientists have used a plant-based system to make shelf-stable drugs. The researchers confirmed the viability of their method for FDA approval and human use, producing an effective drug that promotes ... read more

Oct. 1, 2015 — A novel mechanism of protein resurrection has been discovered, which not only restores the active function of the protein, but also increases its original activity by almost two times. The scientists ... read more

DNA-Based Vaccine Clears Nearly Half of Precancerous Cervical Lesions in Clinical Trial

Sep. 30, 2015 — Using a novel synthetic platform for creating vaccines a team of researchers has successfully eradicated precancerous cervical lesions in nearly half of the women who received an investigational ... read more

'Zelda' Protein Plays Flap-Open Role in Early Embryo Development, Researchers Find

Sep. 29, 2015 — Biologists have identified a mechanism that promotes activation of genes critical for the initiation of embryonic development. Our genes are activated by regulatory factors that bind to the control ... read more

New Test Detects All Viruses That Infect People, Animals

Sep. 29, 2015 — A new test detects virtually any virus that infects people and animals, according to new research. The new test could be used to detect outbreaks of deadly viruses such as Ebola, Marburg and severe ... read more

Sep. 29, 2015 — Intratumor morphological heterogeneity (diversity) of breast cancer is not related to chromosome aberrations. This conclusion was made based on the study of one case with aggressive variant of breast ... read more

Five Genetic Regions Implicated in Cystic Fibrosis Severity

Sep. 29, 2015 — If you have two faulty copies of the CFTR gene, you will have cystic fibrosis. But the severity of your disease will depend partly on many other genes. Now, researchers report that five regions of ... read more

Experts Call for the Responsible Use of New Genome Editing Techniques
