Glaucoma is one of the most common causes of vision loss in North America. It affects 250,000 Canadians – but only half of them know that they have it. There are usually no warning signs therefore it can go undetected unless people are screened yearly after a certain age: 55 years old with no family history and 45 years old or earlier with a family history.
At St. Mary's Hospital Center, about 10,000 patients are treated per year in the eye clinic and approximately 10% have glaucoma. Risk factors associated with glaucoma include: age, diabetes, family history of glaucoma, thick glasses (hyperopia), previous trauma or surgery.
“Regular annual eye exams by a qualified optometrist are necessary as they can help to detect various health problems such as glaucoma and cataracts, explains Dr. Conrad Kavalec, MD, FRCS(C), Chief of the department of ophthalmology at St Mary's and assistant professor at McGill University. If a problem is detected, the patient is referred to an ophthalmologist”.
While St. Mary's is well known as the largest cataract surgery center in Quebec, Dr. Kavalec emphasizes that “Many of our surgeons are not just cataract surgeons but are sub-specialists in ophthalmology with expertise in glaucoma, cornea, oculoplastic, pediatric ophthalmology, retina, neuro-ophthalmology and ocular oncology.”About Ophthalmology at St. Mary’s

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
