New target for common heart condition identified

New target for common heart condition identified

Jan. 8, 2013 — Researchers have found new evidence that metabolic stress can increase the onset of atrial arrhythmias, such as atrial fibrillation (AF), a common heart condition that causes an irregular and often abnormally fast heart rate. Continue reading

Gene therapy reprograms scar tissue in damaged hearts into healthy heart muscle

Gene therapy reprograms scar tissue in damaged hearts into healthy heart muscle

Jan. 4, 2013 — A cocktail of three specific genes can reprogram cells in the scars caused by heart attacks into functioning muscle cells, and the addition of a gene that stimulates the growth of blood vessels enhances that effect, said researchers from Weill Cornell Medical College, Baylor College of Medicine and Stony Brook University Medical Center in a report that appears online in the Journal of the American Heart Association .

Editing genome with high precision: New method to insert multiple genes in specific locations, delete defective genes

Editing genome with high precision: New method to insert multiple genes in specific locations, delete defective genes

Jan. 3, 2013 — Researchers at MIT, the Broad Institute and Rockefeller University have developed a new technique for precisely altering the genomes of living cells by adding or deleting genes. The researchers say the technology could offer an easy-to-use, less-expensive way to engineer organisms that produce biofuels; to design animal models to study human disease; and to develop new therapies, among other potential applications.

Jan. 3, 2013 — Did you ever wish you could be just a teensy bit taller? Well, if you spend a few months in space, you could get your wish — temporarily Continue reading

For those short on time, aerobic, not resistance, exercise is best bet for weight- and fat loss

For those short on time, aerobic, not resistance, exercise is best bet for weight- and fat loss

Jan. 2, 2013 — A new study led by North Carolina researchers has found that when it comes to weight- and fat loss, aerobic training is better than resistance training. The study is believed to the largest randomized trial to directly compare changes in body composition induced by comparable amounts of time spent doing aerobic and resistant training, or both in combination, among previously inactive overweight or obese non-diabetic adults.
