Scientists discover new class of cells expressing olfactory receptors in human airways

Your nose is not the only organ in your body that can sense cigarette smoke wafting through the air. Scientists at Washington University in St. Louis and the University of Iowa have showed that your lungs have odor receptors as well.

Primary cilia play key role in stem cell differentiation

Researchers at Queen Mary University of London have shown for the first time that the specialised role stem cells go on to perform is controlled by primary cilia -tiny hair-like structures protruding from a cell.

WUSTL engineers apply new imaging technique to understand brain’s biomechanics

The human body has a lot of jobs to do, and its mechanical features, such as strength and flexibility, are important to how well it does them. Washington University in St. Louis engineers are now applying a new imaging technique to a model of brain tissue to see how stiff or soft it might be.

BESTCILIA project aims to improve screening, treatment of Primary Ciliary Dyskinesia

Primary Ciliary Dyskinesia is mainly a lung disease: a rare, genetically heterogeneous disorder resulting from dysfunction of small hair-like organelles (cilia) that clean the upper and lower airways. It can also affect multiple organs beside the respiratory system, and may cause serious impairment and lower quality of life. Its prevalence is estimated to be about 1 in 16,000.

Kentucky researcher uses advanced biomedical technology to study HMPV

You may not know the human metapneumovirus by name, but chances are that you have met somewhere before.

New insights on cochlea may help develop better hearing devices

A healthy ear is much better at detecting and transmitting sound than even the most advanced hearing aid. But now researchers reporting in the August 20 issue of the Biophysical Journal, a Cell Press publication, have uncovered new insights into how the ear -- in particular, the cochlea -- processes and amplifies sound.

Researchers pinpoint role of Arl13b gene in guiding placement of neurons during brain development

Researchers have pinpointed the role of a gene known as Arl13b in guiding the formation and proper placement of neurons in the early stages of brain development. Mutations in the gene could help explain brain malformations often seen in neurodevelopmental disorders.

Discovery sheds new light on causes of debilitating diseases and birth defects

Danish researchers have just published findings that explain a previously unknown mechanism used by cells to communicate with one another. The research significantly contributes to understanding why some children are born with malformations and why children and adults may develop life-threatening diseases.

Researchers create 3D map of rod sensory cilium architecture affected by mutation

Using a new technique called cryo-electron tomography, two research teams at Baylor College of Medicine (www.bcm.edu) have created a three-dimensional map that gives a better understanding of how the architecture of the rod sensory cilium (part of one type of photoreceptor in the eye) is changed by genetic mutation and how that affects its ability to transport proteins as part of the light-sensing process.

Study reveals how interneurons navigate during cerebral cortex development

As the brain develops, each neuron must find its way to precisely the right spot to weave the intricate network of links the brain needs to function. Like the wiring in a computer, a few misplaced connections can throw off functioning for an entire segment of the brain.

New understanding of how noise can break critical tip link protein structure in inner ear cells

Researchers have mapped the precise 3-D atomic structure of a thin protein filament critical for cells in the inner ear and calculated the force necessary to pull it apart.

Stereocilia not only move sideways but also change in length: Study

The sensory cells of the inner ear have tiny hairs called stereocilia that play a critical part in hearing. It has long been known that these stereocilia move sideways back and forth in a wave-like motion when stimulated by a sound wave. After having designed a microscope to observe these movements, a research team at Karolinska Institutet in Sweden has discovered that the hairs not only move sideways but also change in length.

UMass Amherst biophysicist receives 2013 Margaret Oakley Dayhoff Award

University of Massachusetts Amherst biophysicist Jenny Ross has won one of the top national honors in her field, the 2013 Margaret Oakley Dayhoff Award, from the Biophysical Society of Rockville, Md. It is given to a woman who has achieved prominence for "substantial contributions to science," while showing very high promise for ideas and leadership in the early stages of her biophysical research career.

Gene therapy approach restores ability to smell in mouse model of congenital anosmia

Scientists funded by the National Institutes of Health have restored the ability to smell in a mouse model of a human genetic disorder that causes congenital anosmia-the inability to smell from birth. The approach uses gene therapy to regrow cilia, cell structures that are essential for olfactory function.

Scientists restore sense of smell in mice through gene therapy

Scientists have restored the sense of smell in mice through gene therapy for the first time -- a hopeful sign for people who can't smell anything from birth or lose it due to disease.

Study helps explain how human airways clear sticky mucus out of the lungs

A runny nose and a wet cough caused by a cold or an allergy may not feel very good. But human airways rely on sticky mucus to expel foreign matter, including toxic and infectious agents, from the body.

Study explains why patients with sinusitis sneeze more often than others

Who would have thought that our noses and Microsoft Windows' infamous blue screen of death could have something in common? But that's the case being made by a new research report appearing online in The FASEB Journal.

Orc1 mutations may explain pathology in manifestations of Meier-Gorlin syndrome

Research published Aug. 1 by scientists at Cold Spring Harbor Laboratory (CSHL) links gene mutations found in some patients with Meier-Gorlin syndrome (MGS) with specific cellular dysfunctions that are thought to give rise to a particularly extreme version of dwarfism, small brain size, and other manifestations of abnormal growth which generally characterize that rare condition.

WCMC receives NHLBI grant to study smoking-induced COPD

Researchers at Weill Cornell Medical College were awarded a $6.5 million grant from the National Heart, Lung, and Blood Institute for a five-year investigation into metabolic changes occurring within airway epithelial cells in the lungs of chronic obstructive pulmonary disease (COPD) patients caused by cigarette smoking. In addition, researchers aim to identify which cigarette smokers are at highest risk of developing COPD as well as novel biomarkers to assist in the development of new therapeutic treatments for the disease.

Special surface coating for stents to keep them in place

If a person's windpipe is constricted, an operation in which the surgeon inserts a stent to enlarge the trachea is often the only way to relieve their respiratory distress. But this grid-like implant can slip out of position, closing off the windpipe altogether. Researchers are working on a special surface coating for the stents to keep them in place.
