A targeted approach to treating toxoplasmosis, a parasitic disease, shows early promise in test-tube and animal studies, where it prevented the parasites from making selected proteins. When tested in newly infected mice, it reduced the number of viable parasites by more than 90 percent, researchers from the University of Chicago Medicine report in the Proceedings of the National Academy of Sciences. This precisely focused therapy combines short strands of "antisense" nucleic acid-like...

John Neumann for redOrbit.com - Your Universe Online Every kid knows that we taste with our tongues, however those in the know, understand that this is a very rudimentary viewpoint. When it comes to flavor, the tongue is very basic. Most of our experience of flavor comes from our olfactory system: our nose and sinuses. Professor Barry Smith, director of the Centre for the Study of the Senses at the University of London, explains, “Not only is it not just about your tongue. Very...

People with good hearing also have a keen sense of touch; people with impaired hearing generally have an impaired sense of touch. Extensive data supporting this hypothesis was presented by Dr. Henning Frenzel and Professor Gary R. Lewin of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch, Germany. The two researchers showed that both senses — hearing and touch — have a common genetic basis. In patients with Usher syndrome, a hereditary form of...

Touch sensitivity is hereditary and linked to genetic mechanisms that support hearing Vision and hearing are so crucial to our daily lives that any impairments usually become obvious to an affected person. Although a number of known genetic mutations can lead to hereditary defects in these senses, little is known about our sense of touch, where defects might be so subtle that they go unnoticed. In the 1 May issue of the online, open-access journal PLoS Biology, Gary Lewin's laboratory...

Earth’s Magnetic Field Gives Pigeons Built-in GPS

Certain neurons in the brains of pigeons encode the direction and intensity of the Earth´s magnetic field, giving the birds an inborn internal global positioning system, according to a new study published Thursday in the journal Science. Scientists have long known internal magnetic field receptors exist in many animals, perhaps including humans.  However, the current study is the first to actually describe the brain wiring that uses these receptors to provide a sense of...

People born without a sense of smell experience higher social insecurity and increased risk for depression, according to a study published Mar. 21 in the open access journal PLoS ONE. The authors of the study, led by Ilona Croy of the University of Dresden Medical School in Germany, investigated 32 individuals born without a sense of smell, known as isolated congenital anosmia. They found that the non-smellers did not have significant deviations from the norm in terms of many daily...

Brain Handles Odors In A Different Way

Researchers from the Stowers institute for Medical Research have traced individual odor molecules in the brain to create a new model of how our sense of smell works. While once thought to cluster related smells, researchers have know discovered that the brain reacts to smells in a broader sense. Previous research has shown that the brain handles the senses in a very orderly way. Things that we touch were thought to be mapped together in the somatosensory cortex, things that we heard...

How are 100 billion cells created, each with specific duties? The human brain is evidence that nature can achieve this. Researchers at Linköping University in Sweden have now taken a step closer to solving this mystery. "Knowledge about the mechanisms that diversify neurons and keep them diverse is necessary in order to cultivate and replace nerve cells in the future," says Mattias Alenius, Assistant Professor of Neuroscience, who has published his research breakthrough in the...
