Biophysics researchers recently used short pulses of light to peer into the mechanics of photosynthesis to try and determine the role of molecule vibrations in the energy conversion process that powers life on earth.   

Through photosynthesis, plants and some bacteria turn sunlight, water and carbon dioxide into food for themselves and oxygen for animals to breathe. It's perhaps the most important biochemical process on Earth and scientists don't yet fully understand how it works.  New 'quantum biology' findings could potentially help engineers make more efficient solar cells and energy storage systems and provide evidence for exactly how photosynthesis manages to be so efficient.  

Eosinophillic esophagitis (EoE) is a chronic inflammatory disorder of the esophagus. The condition is triggered by allergic hypersensitivity to certain foods and an over-accumulation in the esophagus of white blood cells called eosinophils.

EoE can cause a variety of gastrointestinal complaints including reflux-like symptoms, vomiting, difficulty swallowing, tissue scarring, fibrosis, the formation of strictures and other medical complications. 

New research has identified a novel genetic and molecular pathway in the esophagus that causes eosinophillic esophagitis, opening up potential new therapeutic strategies for an enigmatic and hard-to-treat food allergy. 

A decreased ability to identify odors might indicate the development of cognitive impairment and Alzheimer's disease, according to results of research reported at the Alzheimer's Association International Conference 2014 in Copenhagen. 

Examinations of the eye could also indicate the build-up of beta-amyloid, a protein associated with Alzheimer's, in the brain.

An international research project has reported that a new oral medication is showing significant progress in restoring vision to patients with Leber congenital amaurosis (LCA). This inherited retinal disease that causes visual impairment ranging from reduced vision to complete blindness, has remained untreatable.  

"This is the first time that an oral drug has improved the visual function of blind patients with LCA," says the study's lead author, Dr. Robert Koenekoop, who is director of the McGill Ocular Genetics Laboratory at The Montreal Children's Hospital of the MUHC, and a Professor of Human Genetics, Paediatric Surgery and Ophthalmology at McGill University. "It is giving hope to many patients who suffer from this devastating retinal degeneration."

An archaeological dig in southeast Turkey has uncovered a large number of clay tokens that would ordinarily been have dated before the invention of writing - but the new find of tokens dates from a time when writing was commonplace, thousands of years after it was previously assumed this technology had become obsolete.

Sound strange? Perhaps not. Researchers compare it to the continued use of ink pens from the early 1800s in the age of computers. 

A new climate model says that southwestern Australia's long-term decline in fall and winter rainfall is caused by increases in man-made greenhouse gas emissions and ozone depletion.
