In a world perfumed by freshly popped popcorn and exhaust fumes, where sea breezes can mingle with the scents of sweet flowers or wet paint, new research has found that humans are capable of discriminating at least one trillion different odors. Howard Hughes Medical Institute (HHMI) scientists determined that our sense of smell is prepared to recognize this vast olfactory palette after testing individuals' ability to recognize differences between complex odors mixed in the laboratory.

Neuroscientists Vanessa Moraïs and Bart De Strooper from VIB and KU Leuven have demonstrated how a defect in the gene Pink1 results in Parkinson's disease. By mapping this process at a molecular level, they have provided the ultimate proof that a deficient energy production process in cells can result in Parkinson's disease. These insights are so revolutionary that they have been published in the leading journal Science.

ROCHESTER, Minn. — March 20, 2014 — Is irritable bowel syndrome (IBS) caused by genetics, diet, past trauma, anxiety? All are thought to play a role, but now, for the first time, researchers have reported a defined genetic defect that causes a subset of IBS. The research was published in the journal Gastroenterology.
WASHINGTON — The implementation of health care reform in Massachusetts – principally the expansion of health insurance coverage to nearly everyone in the state – was associated with a small but consistent increase in emergency department use, according to the findings of a study to be published online today in Annals of Emergency Medicine ("Increased Use of the Emergency Department After Health Care Reform in Massachusetts").
Lincoln, Neb., March 20, 2014 – The nation's left-leaning citizens might be pleased by the findings of a new University of Nebraska study that finds those who live in liberal states tend to be healthier.
But conservatives could also take satisfaction in the same study's conclusion that strong communities also foster better health.
CHAMPAIGN, Ill. — New research from two University of Illinois economics professors who study election trends analyzes how polarization on social issues affects competing candidates' economic platforms.
In the paper, co-authors Stefan Krasa and Mattias Polborn develop a theory of candidate competition that accounts for the influence of both economic and cultural issues on individual voting behavior.
Interim analysis of the intergroup EORTC-LYSA-FIL 20051 H10 trial published in the Journal of Clinical Oncology indicates an increased risk of early relapse when omitting radiotherapy in early PET scan negative patients with stage I/II Hodgkin's lymphoma. Early outcome, however, was excellent in both arms, and the final analysis should reveal whether these initial findings are maintained over time.
BOSTON – Emergency department usage in Massachusetts rose slightly both during and immediately after implementation of a 2006 state law expanding health care access, a sign that broader availability of insurance may increase use of the ED, Beth Israel Deaconess Medical Center researchers report in a study published in the Annals of Emergency Medicine.
HUNTSVILLE, TX (3/20/14) -- Parents who use alcohol, marijuana, and drugs have higher frequencies of children who pick up their habits, according to a study from Sam Houston State University.
Low levels of both oxygen and the powerful blood vessel dilator nitric oxide appear to have an unfortunate synergy for patients with sickle cell disease, researchers report.
Their studies indicate that the two conditions common in sickle cell disease, dramatically increase red blood cells' adhesion to the lining of blood vessels walls and the debilitating pain crises that can result.
A pilot scheme allowing patients to visit GPs outside the area they live in was most popular among younger commuters and people who had moved house but did not want to change their GP, according to a new report by the London School of Hygiene & Tropical Medicine.
If you're rigid with rules and skimpy on affection and dialogue with your kids, they have a greater chance of being obese, according to research presented at the American Heart Association's Epidemiology & Prevention/Nutrition, Physical Activity & Metabolism Scientific Sessions 2014.
Building a strong connection to a social group helps clinically depressed patients recover and helps prevent relapse, according to a new study.
For the paper, Canadian Institute for Advanced Research (CIFAR) Senior Fellow Alexander Haslam, lead author Tegan Cruwys and their colleagues at the University of Queensland conducted two studies of patients diagnosed with depression or anxiety. The patients either joined a community group with activities such as sewing, yoga, sports and art, or partook in group therapy at a psychiatric hospital.
