Understanding Why Animals Are Healthy Offers Path to Precision Medicine

June 29, 2015 — Researchers have identified a mechanism that explains why some mutations can be disease-causing in one genome but benign in another. The researchers compared thousands of human disease-causing ... read more

Genes Responsible for Increased Activity During the Summer

June 29, 2015 — A thermosensory gene changes behavior in warmer climates, new research reveals. Researchers have explored how the biological clock can be affected by the environment by examining the fruitfly ... read more

Upsetting a Fragile Alliance Triggers a Deadly Childhood Disease

June 29, 2015 — SMA is a devastating neuromuscular disorder that robs children of their ability to walk, eat, or breathe. Mostly caused by an inherited flaw in the Survival Motor Neuron (SMN) gene, SMA is presently ... read more

New Knowledge on Bone Tissue, Its Role in Bone Strength or Weakness

June 29, 2015 — Leading experts in the field present the latest research on material properties of bone and how these can impart resilience or fragility to the skeleton. This new knowledge will aide in understanding ... read more

Scientists Develop More Accurate Whole Genome Variant Discovery, Interpretation

June 29, 2015 — Conventional next-generation sequencing (NGS) techniques are able to accurately detect certain types of variation, such as single nucleotide variants and small insertions or deletions, but miss many ... read more

Rare Gene Variant Associated With Middle Ear Infections

June 29, 2015 — Researchers may have taken the first step on the road to understanding why only some people get frequent painful or chronic middle ear infections. The culprit may be rare genetic variants in a gene ... read more

Genes Leave Some Kids Prone to Weakness in Wrist Bones

June 29, 2015 — Pediatric researchers have discovered gene locations affecting bone strength in wrist bones, the most common site for fractures in children. Children with these genetic variants could especially ... read more

Lean but Not Hungry: Molecular Switch for a Healthy Metabolism Discovered

June 29, 2015 — The protein complex mTORC1 is a central regulator of cell metabolism. In the active state, it stimulates anabolic processes and increases the production and storage of proteins and lipids. ... read more

Action Spectrum of Sun Skin Damage Documented

June 26, 2015 — Scientists have documented for the first time the DNA damage that can occur to skin across the full range of ultraviolet radiation from the sun providing an invaluable tool for sun-protection and the ... read more

RNASEH1 Mutations Impair mtDNA Replication, Cause Adult-Onset Mitochondrial Encephalomyopathy

June 26, 2015 — Next Generation Sequencing (NGS) technology offers an incredible opportunity for the rapid and relatively low-cost characterization of individual genomes, giving us a chance to make a substantial ... read more

Researchers Uncover Epigenetic Switches That Turn Stem Cells Into Blood Vessel Cells
