For cells, internal stress leads to unique shapes
Caltech researchers discover that a cell's unique shape results from an internal tug-of-war: the cell needs to maintain structural integrity while also dynamically responding to the pushes and pulls of mechanical stress.

Researchers: Obesity can amplify bone and muscle loss
Florida State University researchers have identified a new syndrome called 'osteosarcopenic obesity' that links the deterioration of bone density and muscle mass with obesity.

Two new species of yellow-shouldered bats endemic to the Neotropics
Lying forgotten in museum collections, two new species of yellow-shouldered bats have been unearthed by scientists at the American Museum of New York and the Field Museum of Natural History and described in the open-access journal ZooKeys. These two new additions to the genus Sturnira are part of a recent discovery of three bats hidden away in collections around the world, the third one still waiting to be officially announced.

Red moon at night; stargazer's delight
Monday night's lunar eclipse proved just as delightful as expected to those able to view it. On the East Coast, cloudy skies may have gotten in the way, but at the National Science Foundation's National Optical Astronomy Observatory near Tucson, Ariz., the skies offered impressive viewing, as seen from the pictures provided here.

Neuron
Mutant protein in muscle linked to neuromuscular disorder
Spinal and bulbar muscular atrophy (SBMA) is a rare inherited neuromuscular disorder characterized by slowly progressive muscle weakness and atrophy. In a new study published in the April 16, 2014, online issue of Neuron, a team of scientists at the University of California, San Diego School of Medicine say novel mouse studies indicate that mutant protein levels in muscle cells are fundamentally involved in SBMA, suggesting an alternative and promising new avenue of treatment.

How kids' brain structures grow as memory develops
Our ability to store memories improves during childhood, associated with structural changes in the hippocampus and its connections with prefrontal and parietal cortices. New research from UC Davis is exploring how these brain regions develop at this crucial time. Eventually, that could give insights into disorders that typically emerge in the transition into and during adolescence and affect memory, such as schizophrenia and depression.

Surveillance colonoscopy recommendations for average-risk patients with 1 to 2 small polyps consistent with guidelines
According to a new study, endoscopists' recommendations for timing of surveillance colonoscopy in average-risk patients with one to two small polyps are consistent with guideline recommendations in about 90 percent of cases. This may be an appropriate target for quality indicators. This is the first multicenter endoscopic database study to quantify adherence to guidelines for timing of repeat colonoscopy after one to two small polyps are found during screening colonoscopy in average-risk patients.

Gate for bacterial toxins found
Prof. Dr. Dr. Klaus Aktories and Dr. Panagiotis Papatheodorou from the University of Freiburg have discovered the receptor responsible for smuggling the toxin of the bacterium Clostridium perfringens into the cell. The TpeL toxin is formed by C. perfringens, a pathogen that causes gas gangrene and food poisoning. It is very similar to the toxins of many other hospital germs of the genus Clostridium. Aktories is member of the BIOSS Centre for Biological Signalling Studies.

Fertility and Sterility
Preterm births, multiples, and fertility treatment
While it is well known that fertility treatments are the leading cause of increases in multiple gestations and that multiples are at elevated risk of premature birth, these results are not inevitable, concludes an article in Fertility and Sterility. The article identifies six changes in policy and practice that can reduce the odds of multiple births and prematurity, including expanding insurance coverage for in vitro fertilization and improving doctor-patient communications about the risks associated with twins.

Significant baseline levels of arsenic found in Ohio soils are due to natural processes
Geologic and soil processes are to blame for significant baseline levels of arsenic in soil throughout Ohio, according to a new study. The findings pose a challenge for regulators, who must determine what levels should trigger action when natural arsenic levels everywhere are above suggested screening standards.

Neuron
Eavesdropping on brain cell chatter
Everything we do -- all of our movements, thoughts and feelings -- are the result of neurons talking with one another, and recent studies have suggested that some of the conversations might not be all that private. Brain cells known as astrocytes may be listening in on, or even participating in, some of those discussions. But a new mouse study suggests that astrocytes might only be tuning in part of the time -- specifically, when the neurons get really excited about something.

Vanderbilt researchers discover how intestinal cells build nutrient-absorbing surface
The 'brush border' -- a densely packed array of finger-like projections called microvilli -- covers the surfaces of the cells that line our intestines. Vanderbilt University researchers have now discovered how intestinal cells build this specialized structure, which is critical for absorbing nutrients and defending against pathogens. The findings, published April 10 in Cell, reveal a role for adhesion molecules in brush border assembly and increase our understanding of intestinal pathologies associated with inherited and infectious diseases.

Scientists unlock secrets of protein produced by disease-causing fungus
The fungal pathogen Candida albicans causes yeast infections, diaper rashes and oral thrush, and is the most common fungal pathogen to infect humans. It can also cause a life-threatening infection of the blood called disseminated candidiasis. In a new study, scientists from San Antonio and Baltimore determined the three-dimensional structure of a never-before-seen cell wall protein called SOD5 that the organism uses as a defense against the human immune system.

Rice U. study: Performance measures for CEOs vary greatly
As companies file their annual proxy statements with the US Securities and Exchange Commission this spring, a new study by Rice University and Cornell University shows just how S&P 500 companies have tied CEO compensation to performance. The study found large variations in the choice of performance measures, and the researchers said that companies tend to choose measures that are informative of CEO actions.

Scratching the surface: Microbial etchings in impact glass and the search for life on Mars
Haley M. Sapers and colleagues provide what may be the first report of biological activity preserved in impact glass. Recent research has suggested that impact events create novel within-rock microbial habitats. In their paper, 'Enigmatic tubular features in impact glass,' Sapers and colleagues analyze tubular features in hydrothermally altered impact glass from the Ries Impact Structure, Germany, that are remarkably similar to the bioalteration textures observed in volcanic glasses.
