Scientists Discover Important Mechanism for Muscle Building

March 17, 2014

1 Comment

Researchers identify a key mechanism to how basic muscle architecture is built, finding that mechanical tension is the essential trigger. Skeletal muscles are built from small contractile units, the sarcomeres. Many of these sarcomeres are connected in a well-ordered series to form myofibrils that span from one muscle end to the other. Contractions of these […]

New Study Shows that IRX3 Is Likely the “Fat Gene”

March 13, 2014

0 Comments

A new study shows that the IRX3 gene controls body mass and regulates body composition, and appears to be the functional obesity gene. Mutations within the gene FTO have been implicated as the strongest genetic determinant of obesity risk in humans, but the mechanism behind this link remained unknown. Now, an international team of scientists […]

Study Reveals Combination Therapies That Combat HIV at Cell Junctions

February 28, 2014

0 Comments

New research from Yale University reveals that cell-to-cell transmission of HIV particles contributes to the development of full-blown AIDS and helps predict which anti-retroviral therapies will be most effective at keeping the disease at bay. The new research reinforces recent findings that a heavy concentration of the virus at the point of contact between cells […]

Study Shows Crude Oil Impairs Cardiac Excitation-Contraction Coupling in Fish

February 18, 2014

0 Comments

While studying the impact of the Deepwater Horizon oil spill, Stanford researchers discovered that crude oil interrupts a cellular pathway that allows fish heart cells to beat effectively. Scientists from Stanford University and the National Oceanic and Atmospheric Administration (NOAA) have discovered that crude oil interferes with fish heart cells. The toxic consequence is a […]

Yale Researchers Find Hope for Safe and Novel Painkillers from Tarantula Venom

February 17, 2014

0 Comments

Yale researchers find new hope for safe and novel painkillers from the venom of the Peruvian green velvet tarantula. Screening more than 100 spider toxins, Yale researchers identified a protein from the venom of the Peruvian green velvet tarantula that blunts activity in pain-transmitting neurons. The findings, reported in the March 3 issue of the […]

Study Reveals Shivering and Exercise Equally Convert White Fat to Brown

February 5, 2014

0 Comments

New research from the Garvan Institute of Medical Research reveals that shivering and bouts of moderate exercise are equally capable of converting “white fat” into “brown fat.” A new study suggests that shivering and bouts of moderate exercise are equally capable of stimulating the conversion of energy-storing ‘white fat’ into energy-burning ‘brown fat’. Around 50 […]

Researchers Identify Major Obstacle to Converting Cells Back to Their Youthful State

January 31, 2014

2 Comments

Researchers from Yale University have identified a major obstacle to converting cells back to their youthful state — the speed of the cell cycle, or the time required for a cell to divide. A fundamental axiom of biology used to be that cell fate is a one-way street — once a cell commits to becoming […]

Researchers Discover New Link between Processes Associated with a Parkinson’s Related Gene Defect

January 30, 2014

1 Comment

Researchers from the Max Planck Institute have discovered a new link between processes associated with a Parkinson’s-related gene defect, paving the way to the development of more refined GDNF therapies in the future. Neurodegenerative diseases like Parkinson’s disease involve the death of thousands of neurons in the brain. Nerve growth factors produced by the body, […]

Scientists Sequence the Genome of the World’s Oldest Continuously Surviving Cancer

January 24, 2014

2 Comments

Researchers have sequenced the genome of an 11,000-year-old dog cancer, revealing its secrets and origin. Scientists have sequenced the genome of the world’s oldest continuously surviving cancer, a transmissible genital cancer that affects dogs. This cancer, which causes grotesque genital tumors in dogs around the world, first arose in a single dog that lived about […]
