Acoustics of ancient Greek theaters found to be good, not great

Tales of the acoustics at the 2300 year-old Greek theater of Epidaurus tend to be told in terms of superlatives. Not actually justified, according to measurements taken by researchers from Eindhoven University of Technology. They are the first to detail the acoustics of three ancient theaters, with over 10,000 measurements, which confirms that when actors speak very loudly, they can be understood perfectly well right up to the back row. However, the tearing of a piece of paper or a whisper is only audible up to about halfway up, in contradiction to the many claims.

Maternal diet may program child for disease risk, but better nutrition later can change that

Research has shown that a mother's diet during pregnancy, particularly one that is high-fat, may program her baby for future risk of certain diseases such as diabetes. A new study from nutrition researchers at the University of Illinois shows that switching the offspring to a new diet—a low-fat diet, in this case—can reverse that programming.

New gene editing approach for alpha-1 antitrypsin deficiency shows promise

A new study by scientists at UMass Medical School shows that using a technique called "nuclease-free" gene editing to correct cells with the mutation that causes a rare liver disease leads to repopulation of the diseased liver with healthy cells. Alpha-1 antitrypsin deficiency is an inherited disease that causes liver and lung damage; the Mueller lab's approach to the disease, led by postdoc Florie Borel, PhD, and published in the journal Molecular Therapy, combines the use of RNA interference with gene augmentation, using an RNAi-resistant version of the alpha-1 antitrypsin gene. This dual treatment has the potential to prevent both liver and lung damage from forming in very young patients.

Xuetao Cao with the Chinese Academy of Medical Sciences offers a Perspective piece on the work done by the team in the same journal issue and suggests that the work might one day lead to the development of new kinds of treatments for common bowel disorders.

The skinny on lipid immunology

Phospholipids - fat molecules that form the membranes found around cells - make up almost half of the dry weight of cells, but when it comes to autoimmune diseases, their role has largely been overlooked. Recent research has pointed to a role for them in numerous diseases, including psoriasis, contact hypersensitivities and allergies. In a new study published in Science Immunology, researchers from Brigham and Women's Hospital and Monash University in Australia reveal new insights into the basis for T cell receptor (TCR) autoreactivity to self-phospholipids, with implications for autoimmune diseases.

Professor Katariina Salmela-Aro points out that autonomy support provided by mothers and fathers prevented depression during all three transitions and increased the self-esteem of youths in the final two transitions. The study was performed with funding from the Academy of Finland.

Researchers study cellular processes dependent on calcium ions

Calcium-ATPases convey calcium ions (Ca2+) from the cytoplasm to the extracellular space via active transport (using ATP as an energy source), and thus fundamentally contribute to the control of a wide variety of Ca2+-dependent processes in virtually any type of cell in humans and animals. Scientists in the group of Dr. Uwe Schulte and Prof. Dr. Bernd Fakler at the University of Freiburg have successfully unraveled the molecular appearance of this well-known ion pump: Ca2+-pumps of the plasma membrane (PMCAs) are identified as protein complexes that are assembled from two ATP-hydrolyzing transporter proteins and two as-yet unknown subunits, neuroplastin and basigin. These two novel protein subunits are essential for stability and trafficking of the PMCA complexes to the plasma membrane and control the PMCA-mediated Ca2+-transport. The researchers have published their work in Neuron.

Treating depression—an expert discusses risks, benefits of ketamine

Up to a third of patients with depression don't respond to traditional forms of treatment. For those patients, the dark fog that hovers over their lives feels like it will never lift. But a new treatment called ketamine has recently made waves all over the internet. Hailed as a "miracle drug" and the first major antidepressant breakthrough in three decades, ketamine has improved the lives of many patients whose depression had dominated their lives for years. And yet, many of these articles also convey a note of skepticism. That's because ketamine is also a street drug, a popular hallucinogenic known as "special K."

Bacterial pathogens outwit host immune defences via stealth mechanisms

Despite their relatively small genome in comparison to other bacteria, mycoplasmas can cause persistent and often difficult-to-treat infections in humans and animals. An extensive study by researchers from Vetmeduni Vienna has now shown how mycoplasmas escape the immune response despite their minimal "genetic arsenal". Mycoplasmas vary their surface as needed by switching from one gene variant to an alternative when the first is recognized by the immune system: Mycoplasmas "mask" themselves. They use their small genome in such a clever strategic way that they can even compensate for the loss of an enzyme that is important for this process. This could be shown for the first time in vivo in a living host organism, thus representing a breakthrough in the research of this special group of bacterial pathogens. The study was published in PLOS Pathogens.

Dying a good death—what we need from drugs that are meant to end life

The team has already been able to halt this mechanism with an antibody treatment.

'Antelope perfume' keeps flies away from cows

In Africa, tsetse flies transfer sleeping sickness to cattle. This leads to huge losses in milk, meat and manpower. The damage in Africa is estimated to be about $4.6 billion U.S. each year. Prof. Dr. Christian Borgemeister from the Center for Development Research (ZEF) at the University of Bonn and his colleagues from Kenya and the UK have developed an innovative way of preventing the disease. The scientists took advantage of the fact that tsetse flies avoid waterbucks, a widespread antelope species in Africa. The scientists imitated the smell of these antelopes. Eighty percent of cattle equipped with collars containing the defense agent were spared from the infection. This research results are presented in PLOS Neglected Tropical Diseases.

Physical inactivity and restless sleep exacerbate genetic risk of obesity
