Team to create realistic model of human vocal cords
Our vocal cords, two multilayered folds of tissue located above the trachea, produce voice when air passes between them and sets them into vibration. (more…)

Is hair the root to understanding our stress levels?
Women with lower incomes have higher concentrations of the stress hormone cortisol in their hair, according to a new study from UCL.
The study also found that women whose income has gone up over the last 4 years have lower cortisol levels than those whose income went down, suggesting an association between long-term financial strain and stress hormones. (more…)

Neuronale Schaltkreise für natürliches Sehen
Neues Netzwerkmodell soll Einsichten in die Verarbeitung von natürlichen Reizen in der Sehrinde ermöglichen
Rund um die Uhr empfangen und verarbeiten neuronale Schaltkreise im Gehirn Informationen der Sinneswahrnehmung und ermöglichen dadurch, dass Mensch und Tier ihre Umwelt wahrnehmen und mit ihr interagieren. Schon lange versuchen Forscherinnen und Forscher herauszufinden, wie das Sehsystem natürliche Reize, also das gewöhnliche Sehen im Alltag, verarbeitet. Eine neue Entwicklung könnte bisher ungeahnte Einsichten liefern: Die Neurowissenschaftler Dr. Jens Kremkow und Prof. Dr. Ad Aertsen vom Bernstein Center Freiburg der Albert-Ludwigs-Universität haben gemeinsam mit einem Team des französischen Centre Nationale de la Recherche Scientifque (CNRS) in Marseille, des CNRS in Gif-Sur-Yvette und der New York State University/USA ein Netzwerkmodell erstellt, das simuliert, wie die Sehrinde – das fürs Sehen zuständige Areal in der Großhirnrinde – sensorische Reize auswertet. Das Modell könnte dabei helfen, die Verarbeitung natürlicher Reize im Sehsystem besser zu verstehen. Die Studie wurde in der Fachzeitschrift „Frontiers in Neural Circuits“ veröffentlicht.
Saving lives and limbs: 30 years of interventional cardiology at Yale
Three years ago, Richard Kenney of Branford, Connecticut noticed he was getting winded when he climbed a flight of stairs or tried to go for a walk. “I had a heart murmur, but I was also getting short of breath,” said the retired octogenarian and former business owner. (more…)
For treating a leading cause of osteoporosis, surgery is better than widely used medications
UCLA study finds that using drugs to combat hyperparathyroidism is worse than doing nothing at all
While most cases of osteoporosis are caused by normal aging, another leading cause of the bone-loss disease is a condition called hyperparathyroidism, in which the parathyroid glands release an excessive amount of a hormone that regulates the body’s calcium levels. (more…)
Ivy’s powerful grasp could lead to better medical adhesives, stronger battle armor
Study uncovers molecular explanation for one of nature’s most effective glues
COLUMBUS, Ohio – English ivy’s natural glue might hold the key to new approaches to wound healing, stronger armor for the military and maybe even cosmetics with better staying power. (more…)
New method of drug delivery may be safer and more effective against pancreatic cancer
UCLA researchers use nanoparticles to send chemotherapy drug directly to the tumor site, reducing damage to healthy tissues
The overall five-year survival rate for people with pancreatic cancer is just 6 percent, and there is an urgent need for new treatment options. More than 80 percent of pancreatic cancer diagnoses occur too late for surgery, making chemotherapy the only possible treatment. (more…)
