Nature Communications
When things get glassy, molecules go fractal
School children learn the difference between liquids and gases, but centuries of scholarship have failed to produce consensus about how to categorize glass. Now, combining theory and numerical simulations, researchers have resolved an enduring question in the theory of glasses, showing that their energy landscapes are far rougher than previously believed. The new model shows that molecules in glassy materials settle into a fractal hierarchy of states.

Fruit fly study identifies brain circuit that drives daily cycles of rest, activity
Researchers describe a circuit in the brain of fruit flies that controls their daily, rhythmic behavior of rest and activity. They also found that the fly version of the human brain protein known as corticotrophin releasing factor is a major coordinating molecule in this circuit.

Oldest pterodactyloid species discovered, named by international team of researchers
An international research team, including a George Washington University professor, has discovered and named the earliest and most primitive pterodactyloid -- a group of flying reptiles that would go on to become the largest known flying creatures to have ever existed -- and established they flew above the earth some 163 million years ago, longer than previously known.

Researchers pinpoint protein crucial for development of biological rhythms in mice
Johns Hopkins researchers report that they have identified a protein essential to the formation of the tiny brain region in mice that coordinates sleep-wake cycles and other so-called circadian rhythms. By disabling the gene for that key protein in test animals, the scientists were able to home in on the mechanism by which that brain region, known as the suprachiasmatic nucleus or SCN, becomes the body's master clock while the embryo is developing.

New guidelines aim to improve care for babies with heart problems in the womb
Heart experts have developed the first scientific statement on detecting, managing and treating heart abnormalities in the womb. Medicines, fetal procedures, careful monitoring and strategies for delivery room care are improving the health of babies with heart abnormalities from before birth and beyond. Providers should help families overcome anxiety and depression, so they can transition from grief to acceptance and become active members of the team that cares for their baby.

Surprising new insights into the PTEN tumor suppressor gene
Ever since it was first identified more than 15 years ago, the PTEN gene has been known to play an integral role in preventing the onset and progression of numerous cancers. Now investigators at Beth Israel Deaconess Medical Center explain more precisely how PTEN exerts its anti-cancer effects and how its loss or alteration can set cells on a cancerous course.

Researchers create comprehensive map of human B cell development
A Columbia and Stanford team describes a new method for mapping cellular development at the single cell level. By combining emerging technologies with a new, advanced computational algorithm, they created the most comprehensive map ever made of human B cell development. The approach will improve the ability to investigate development in cells of all types, help identify rare aberrations that lead to disease, and guide the next generation of research in regenerative medicine.

Muscle mass linked with physical function and quality of life in dialysis patients
Dialysis patients with higher BMI, waist circumference, and abdominal fat measures had poorer scores on a 6-minute walking test. Patients with more muscle mass had better scores on the walking test as well as better scores on physical and mental health questionnaires.

Many patients who could benefit from home dialysis are receiving care in dialysis centers
In Australia, kidney failure patients from the most advantaged areas were less likely to use home dialysis and more likely to use in-center hemodialysis than patients from the most disadvantaged areas. Patients from the most advantaged areas were more likely to use private hospitals than those from the most disadvantaged areas.

Low-dose natural antimicrobial exacerbates chronic lung infection in cystic fibrosis
Respiratory failure caused by chronic lung infection with Pseudomonas aeruginosa bacteria is a common cause of death in patients with cystic fibrosis, a genetic disease that is common in individuals of European descent. A study published on April 24 in PLOS Pathogens demonstrates that an antimicrobial peptide produced by human immune cells can promote mutations in the bacterium that make it more lethal.

Researchers discover new genetic brain disorder in humans
A newly identified disorder affecting the human nervous system is caused by a mutation in a gene never before implicated in human disease. By performing DNA sequencing of children affected by neurological problems, two research teams discovered that a disease marked by reduced brain size, as well as sensory and motor defects, is caused by a mutation in a gene called CLP1. Insights into this disorder may have implications for the treatment of common disorders.

International collaboration unravels novel mechanism for neurological disorder
A team of international scientists led by Baylor College of Medicine has discovered a novel gene (CLP1) associated with a neurological disorder affecting both the peripheral and central nervous systems. Together with scientists in Vienna they show that disturbance of a very basic biological process, tRNA biogenesis, can result in cell death of neural progenitor cells. This leads to abnormal brain development and a small head circumference as well as dysfunction of peripheral nerves.

New study links inflammation in those with PTSD to changes in microRNA
With a new generation of military veterans returning home from Iraq and Afghanistan, post-traumatic stress disorder (PTSD) has become a prominent concern in American medical institutions and the culture at-large. Estimates indicate that as many as 35 percent of personnel deployed to Iraq and Afghanistan suffer from PTSD. New research from the University of South Carolina School of Medicine is shedding light on how PTSD is linked to other diseases in fundamental and surprising ways.
