Blowing Bubbles Just Went High-Tech With Images And Scents
2014-04-24 08:39:02

[ Watch the Video: SensaBubble - A Chrono-Sensory Mid-Air Display Of Sight And Smell ] Lawrence LeBlond for redOrbit.com - Your Universe Online Surely everyone remembers blowing bubbles as a child, one of the simplest forms of pleasure for kids everywhere. Even today, the stressors of modern technology can seem so distant when in the presence of simple, spherical pockets of soapy air. However, one group of scientists is taking simplicity out of the equation and adding technological...

Skin cells use new molecule to send touch information to the brain In a study published in the April 6 online edition of the journal Nature, a team of Columbia University Medical Center researchers led by Ellen Lumpkin, PhD, associate professor of somatosensory biology, solve an age-old mystery of touch: how cells just beneath the skin surface enable us to feel fine details and textures. Touch is the last frontier of sensory neuroscience. The cells and molecules that initiate...

A study led by scientists at The Scripps Research Institute (TSRI) has helped solve a long-standing mystery about the sense of touch. The "gentle touch" sensations that convey the stroke of a finger, the fine texture of something grasped and the light pressure of a breeze on the skin are brought to us by nerves that often terminate against special skin cells called Merkel cells. These skin cells' role in touch sensation has long been debated in the scientific community. The new study,...

A Collage Of Senses Help Sharks Hunt For Food: Study
2014-04-07 11:22:28

[ Watch the Video: Sharks Sense Prey In Surprising Way ] Brett Smith for redOrbit.com - Your Universe Online Sharks are highly-evolved killing machines and a new study published in the open-access journal PLOS ONE has compiled a comprehensive picture of how these marine predators hunt – from start to finish. The study portrays the collage of senses used by sharks to detect, track and strike their prey with ruthless efficiency. The research team – from the University of South...

Jumping bristletail Lepismachilis y-signata

Max Planck Institute for Chemical Ecology Odorant receptors of recent insects evolved long after insects migrated from water to land. An insect’s sense of smell is vital to its survival. Only if it can trace even tiny amounts of odor molecules is it is able to find food sources, communicate with conspecifics, or avoid enemies. According to scientists at the Max Planck Institute for Chemical Ecology, many proteins involved in the highly sensitive odor perception of insects emerged...

Human Nose Can Distinguish More Than 1 Trillion Scents
2014-03-21 04:48:03

redOrbit Staff & Wire Reports - Your Universe Online For decades, experts have claimed that people were capable of detecting 10,000 different odors, but new research appearing in the March 21 edition of Science suggests that the actual number of scents detectable by the human nose is considerably higher. In fact, according to an experiment led by Andreas Keller of the Rockefeller University Laboratory of Neurogenetics and Behavior, human noses and brains are sensitive enough to...

Magnetic Pull Of MRI Could Diagnose, Treat And Study Inner Ear Disorders
2014-03-20 08:52:28

Johns Hopkins Medicine Magnetic pull of MRI shown in zebrafish and in people with common inner-ear disturbance Expanding on earlier research, Johns Hopkins researchers report that people with balance disorders or dizziness traceable to an inner-ear disturbance show distinctive abnormal eye movements when the affected ear is exposed to the strong pull of an MRI's magnetic field. The researchers first reported in 2011 in the journal Current Biology that an MRI's magnetic field pushes...

Scientists at The Scripps Research Institute (TSRI) have discovered an important mechanism underlying sensory feedback that guides balance and limb movements. La Jolla, California (PRWEB) March 13, 2014 Scientists at The Scripps Research Institute (TSRI) have discovered an important mechanism underlying sensory feedback that guides balance and limb movements. The finding, which the TSRI team uncovered in fruit flies, centers on a gene and a type of nerve cell required for detection of...

Colors And Shapes Can Be Heard By The Blind: Study
2014-03-11 06:52:16

[ Watch the Video: EyeMusic Live Demo at AIPAC ] April Flowers for redOrbit.com - Your Universe Online Normally, people perceive colors and shapes visually, but what if you could "hear" them? A new study from Hebrew University shows that using sensory substitution devices (SSDs), colors and shapes can now be conveyed to the brain noninvasively through other senses. Prof. Amir Amedi, of the Edmond and Lily Safra Center for Brain Sciences and the Institute for Medical Research...

The tent-making bat Uroderma bilobatum
2014-03-04 05:07:25

Brett Smith for redOrbit.com - Your Universe Online While scientists know that a superfamily of genes inside olfactory receptors is responsible for our sense of smell – we still don’t know the mechanism behind the interpretation of odor molecules into a particular smell. A new study published in the journal Molecular Biology and Evolution has found a distinct gene pattern in the olfactory receptors of fruit-eating bats – potentially shedding some light on the mechanism behind our...
