A diagnosis of obstructive sleep apnea may raise the risk of osteoporosis, particularly among women or older individuals, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism (JCEM).

Fragile X syndrome is the most common inherited form of mental retardation, caused by loss of function of the gene for a protein called fragile X mental retardation protein (FMRP). A new study in the fruit fly (Drosophila melanogaster) indicates that the normal function of this protein is to bind directly to the ribosomes, which are the structures in the cell on which proteins are synthesised, and selectively inhibit translation of proteins. The study, published on 17th April in the Cell Press journal Molecular Cell, is from researchers in the University of California, the Wadsworth Center, New York State Department of Health and the State University of New York at Albany.

Circadian behavioural responses to light input in fruit flies (Drosophila) depends on two groups of neurons, called the morning and evening oscillators ‘talking’ to each other. Previously it had been thought that these groups of neurons worked autonomously in scheduling peaks of activity at dawn and dusk, but a new study proves that they cooperate. The study published in the Cell Press journal Cell Reports on April 17th comes from researchers in the University of Massachusetts.

 A procedure called lung volume reduction surgery could be performed effectively in more patients, according to new research. Chronic obstructive pulmonary disease (COPD) is a combination of emphysema (damage to the air sacs of the lungs) and chronic bronchitis. It affects more than a million people in the UK and is a major cause of disability and premature death.

The feelings of wanting to dance to music and experiencing pleasure are influenced by the degree of rhythmic complexity or syncopation. This is the main finding of a study from researchers in the University of Oxford and Aarhus University, Denmark published in the journal PLoS One on April 16th 2014.

For a long time, researchers thought that the star-shaped astrocytes (the name comes from the Greek word for star) were simply support cells for the neurons. It turns out that these cells have a number of important jobs, including providing nutrients and signaling molecules to neurons, regulating blood flow, and removing brain chemicals called neurotransmitters from the synapse. The synapse is the point of information transfer between two neurons. At this connection point, neurotransmitters are released from one neuron to affect the electrical properties of the other. Long arms of astrocytes are located next to synapses, where they can keep tabs on the conversations going on between neurons.
