Discovered! Link between heart, blood, and skeletal muscle
Gene thought to make heart tissues turns out to make blood and muscles as well!

Heart cells change stem cell behavior
Rice University, Texas Children’s study shows amniotic fluid stem cells and heart cells pass signals between themselves, without touching.

‘Dark genome’ is involved in Rett Syndrome
Researchers have identified alterations in noncoding long chain RNA sequences (lncRNA) in Rett syndrome. Overall, their findings indicate that the transcriptional dysregulation of lncRNAs upon loss of Mecp2 contributes to Rett syndrome and highlights the complex interaction between non coding RNAs (ncRNAs) and coding-RNAs.

Fetus emits hormone to prevent preeclampsia
In a study using mice, researchers found that a hormone, adrenomedullin, plays a crucial role in preventing the pregnancy complication preeclampsia. Surprisingly, this hormone protects women from preeclampsia when emitted by the fetus, not the mother, during the most critical times in pregnancy.

How brain's auditory center transmits information for decisions, actions
Specialized neurons in the auditory cortex 'represent' and transmit the 'votes' of other neurons to the striatum

How a molecule can be involved in cancer and birth defects
Solving the structure of a critical human molecule involved in cancer, scientists at The Scripps Research Institute (TSRI) have found what they call a good example of structural conservation—dissimilar genes that keep very similar shapes.

Celiac disease increases risk for low birth weight babies
The antibody tissue transglutaminase (anti-tTG) is most commonly found in patients with celiac disease. Pregnant women with mid to high levels of anti-tTG are at risk for having babies with reduced fetal weight and birth weight.

Mild iodine deficiency in womb reflects in lowered children's literacy tests
Changes in mother's diet, supplements may prevent long-term neurological impairment.

Lethal childhood disease, GAN, tracked to protein
A team of international researchers has identified how a defective protein plays a central role in a rare, lethal childhood disease known as Giant Axonal Neuropathy, or GAN.

Easy come, easy grow
Even in plants, tightness provokes sperm release.Sperm cell release can be triggered by tightening the grip around the delivery organ, according to a team of nano and microsystems engineers and plant biologists at the University of Montreal and Concordia University.

Uncovered, gene linked to blood vessel formation
University of North Carolina researchers have discovered that disrupting a gene that acts as a regulatory switch to turn on other genes can keep blood vessels from forming and developing properly.

Adult mice lack stem cells for making new eggs
Whether or not mammals generate new eggs in adulthood using stem cells has been a source of scientific controversy. If true, these "germ-line stem cells" might allow new treatments for infertility and other diseases.

How the brain folds to fit
During fetal development of the mammalian brain, the cerebral cortex undergoes a marked expansion in surface area in some species, accommodated by folding of brain tissue and expanded neuron numbers from increased surface area. Researchers have now identified a protein called Trnp1 as key in controlling expansion and folding.

Converting bad fat to good fat
For the first time, scientists from ETH Zurich have shown that brown and white fat cells in a living organism can be converted from one cell type to the other. Using mice as a model organism, their work provides important new insights into the origin of brown fat cells, a prerequisite for developing anti-obesity therapies.

Sunshine hormone, vitamin D, offers hope for treating liver fibrosis
New findings suggest vitamin D therapy could be a powerful weapon in the fight against liver fibrosis and other diseases with a fibrotic component, including those of the lung, kidney and pancreas.
