The Structure of the Nasal Cavity Channels Food Smells into the Nose and Avoids the Lungs

Three-dimensional printing technology was used to create a model of the nasal cavity that enabled researchers to demonstrate why the smell of food goes into the nose rather than down into the lungs.  More...

Selective Ribosome-Targeting Drug with Low Ototoxicity Could Provide Safer Treatment Option for Leishmaniasis

In a multidisciplinary biological study, researchers have shed new light on the mechanism of action of a potent drug for leishmaniasis, the natural aminoglycoside paromomycin, and have found that a new synthetic derivative of PAR may provide a far lower risk of irreversible hearing loss side-effects, probably via its more selective targeting of cytosolic (vs. mitochondrial) ribosomes.  More...

New Diagnostic Tool on Horizon for Surgeons Treating Cancer Patients

Researchers have successfully developed a new tool that may enable surgeons to determine if a biopsy tissue is cancerous while their patients are still on the operating table, without routinely requiring microscope-based pathology analysis of the tissue.   More...

Cabut Coordinates Metabolism and Clock in Response to Nutrient Sensing

Using a Drosophila fruit fly model to study sugar sensing, researchers have discovered that the transcription factor and developmental growth regulator, cabut, coordinates energy metabolism as well as the circadian clock in response to sugar sensing.  More...
