Modern humans have a better sense of smell than Neanderthals

Compared to Neanderthals, modern humans have a better sense of smell. Differences in the temporal lobes and olfactory bulbs also suggest a combined use of brain functions related to cognition and olfaction. The increase of brain size is intimately linked to the evolution of humanity. Two different human species, Neanderthals and modern humans, have independently evolved brains of roughly the same size but with differing shapes. This could indicate a difference in the underlying brain organization.

Scientists shed light on 3-D structure of olfactory receptor binding site

Banana, mango or apricot - telling these smells apart is no problem for the human nose. How the olfactory organ distinguishes such similar smells has been uncovered by an interdisciplinary team of researchers at the RUB. The scientists were the first to shed light on the dynamics of the three-dimensional structure of the binding site of an olfactory receptor. In so doing, they also found a characteristic pattern of hydrogen bonds between odorant and receptor, which accounts for the specificity of the olfactory sensors.

Indiscriminate expensive imaging has little clinical benefit in patients requiring epidural steroid injections

Johns Hopkins-led research suggests that routine MRI imaging does nothing to improve the treatment of patients who need injections of steroids into their spinal columns to relieve pain. Moreover, MRI plays only a small role in a doctor's decision to give these epidural steroid injections (ESIs), the most common procedure performed at pain clinics in the United States.

Electromechanical wave imaging can diagnose non-periodic arrhythmias

Thanks to a new study from Columbia Engineering School, doctors may now be able to diagnose in their offices non-periodic arrhythmias-noninvasively and at low cost-within a single heartbeat. Non-periodic arrhythmias include atrial and ventricular fibrillation, which are associated with severely abnormal heart rhythm that can in some cases be life-threatening.
