Aside from its recognition and warning functions, olfaction serves many purposes in the CNS and remains one of the most important means of communication with the environment. In addition to olfactory tract input, the olfactory bulb also receives and provides input to other brain centers that modify neuronal activity.

An overview of the effects of tobacco ingredients on smoke chemistry and toxicity.
This paper presents an overview of a series of studies designed to assess the influence of 482 tobacco ingredients on cigarette smoke chemistry and toxicity. The studies are: pyrolysis of the ingredients; influence of the ingredients on smoke constituents believed by regulatory authorities to be relevant to smoking-related diseases ; influence of the ingredients on in vitro genotoxicity and cytotoxicity of smoke partiulate matter; and influence of the ingredients on the inhalation toxicity of smoke.

Jefferson researchers reveal new insight into two states of viral protein
To generate swarms of new viral particles, a virus hijacks a cell into producing masses of self-assembling cages that are then loaded with the genetic blueprint for the next infection. But the picture of how that DNA is loaded into those viral cages, or capsids, was blurry, especially for two of the most common types of DNA virus on earth, bacterial viruses and human herpesvirus.
Living at high altitudes linked to lower risk of developing Metabolic Syndrome
Could something as simple as the geographic area in which you live contribute to your risk of developing heart disease and diabetes, or suffering a stroke? A new study, published in the open-access journal Frontiers in Physiology , has revealed that the incidence of Metabolic Syndrome could be linked to the altitude of where a person lives. Metabolic syndrome is the medical term for the combination of high blood pressure, sugar and cholesterol levels, as well as excess body fat around the waist, and contributes to serious health problems.
Research findings could lead to effective repair therapies for peripheral nerve damage
Research published today, 30th January 2017 online in the Journal of Cell Biology , has for the first time identified how a bodily protein allows nerves of the peripheral nervous system to repair following injury. The findings, discovered by research neuroscientists at Plymouth University Peninsula Schools of Medicine and Dentistry and funded by the Medical Research Council, could lead to effective repair therapies for those who have suffered peripheral nerve damage in trauma cases or perhaps via battlefield injuries.

Globe-trotting pollutants can last longer and travel much farther than previously predicted
A new way of looking at how pollutants ride through the atmosphere has quadrupled the estimate of global lung cancer risk from a pollutant caused by combustion, to a level that is now double the allowable limit recommended by the World Health Organization. The findings, published this week in the Proceedings of the National Academy of Sciences Early Edition online, showed that tiny floating particles can grow semi-solid around pollutants, allowing them to last longer and travel much farther than what previous global climate models predicted.

IU study shows how fruit fly growth shares biochemical similarities with cancer cells
Scientists who study a molecule known to play a role in certain types of cancers and neurodegenerative disorders have a powerful new tool to study this compound due to research conducted at Indiana University. The study, published Jan. 23 in the Proceedings of the National Academy of Sciences , shows how the extreme growth experienced by fruit flies in their earliest stage of life shares biochemical similarities with the growth of cancer cells.

Bodywide immune response important for fighting cancer, Stanford researchers say
Fighting off cancer requires the concerted efforts of immune molecules throughout the body, rather than just in the tumor itself, according to a new study of laboratory mice by researchers at the Stanford University School of Medicine. The finding helps settle an ongoing dispute among clinicians as to whether systemic, or whole-body responses, are as important as a robust response by immune cells in the tumor itself.
