Morphing manganese

Study of St. Lawrence Estuary sediments sheds light on role of manganese in aquatic environments
Fri, 2013-08-23 11:18

An often-overlooked form of manganese, an element critical to many life processes, is far more prevalent in ocean environments than previously known, according to a study by U.S. and Canadian researchers published this week in Science.

Putting sleep disorders to bed

Researchers at McGill and Concordia universities discover new way to improve internal clock function
Wed, 2013-08-21 12:01

Overnight flights across the Atlantic, graveyard shifts, stress-induced insomnia are all prime culprits in keeping us from getting a good night’s sleep. Thanks to new research from McGill University and Concordia University, however, these common sleep disturbances may one day be put to bed.

A new role for sodium in the brain

Findings identify a novel pharmacological target for drug development
Tue, 2013-08-20 11:52

Researchers at McGill University have found that sodium – the main chemical component in table salt – is a unique “on/off” switch for a major neurotransmitter receptor in the brain. This receptor, known as the kainate receptor, is fundamental for normal brain function and is implicated in numerous diseases, such as epilepsy and neuropathic pain.

Alcoholism: effects on the brain's dopamine system

Those vulnerable to alcoholism may experience an unusually large response in the brain’s reward-seeking pathway when they take a drink

Research from McGill University suggests that people who are vulnerable to developing alcoholism exhibit a distinctive brain response when drinking alcohol, according to a new study by Prof. Marco Leyton, of McGill University’s Department of Psychiatry. Compared to people at low risk for alcohol-use problems, those at high risk showed a greater dopamine response in a brain pathway that increases desire for rewards. These findings, published in the journal Alcoholism: Clinical & Experimental Research, could help shed light on why some people are more at risk of suffering from alcoholism and could mark an important step toward the development of treatment options.

New network in medical physics

Initiative funded by NSERC’s CREATE program seeks to bolster innovation in the development of technologies used for diagnosis and treatment of disease
Mon, 2013-08-12 11:01
Greg Rickford

A new network that is bringing together expertise from universities, government and industry is implementing a new vision for training the next generation of medical physicists. Ultrasounds, X-rays, MRIs and nuclear medicine are only a few examples of the essential contributions of medical physicists. The field of medical physics applies the principles of physics to medicine, from diagnosis to treatment, and seeks to quickly transform scientific discovery into clinical applications. Medical physicists are also clinical health care professionals providing service in fields such as radiation therapy, medical imaging, nuclear medicine or radiation protection, to name a few.

Understanding the effects of genes on human traits

Montreal Scientists develop a novel approach for scanning the entire genome
Thu, 2013-08-01 11:09

Recent technological developments in genomics have revealed a large number of genetic influences on common complex diseases, such as diabetes, asthma, cancer or schizophrenia. However, discovering a genetic variant predisposing to a disease is only a first step. To apply this knowledge towards prevention or cure, including tailoring treatment to the patient’s genetic profile –also known as personalized medicine – we need to know how this genetic variant affects health.

Quantum of sonics: Bonded, not stirred

McGill researchers discover new way to bond particles using ultrasound to form new materials
Wed, 2013-07-31 11:25

Researchers at McGill University have discovered a new way to join materials together using ultrasound. Ultrasound – sound so high it cannot be heard – is normally used to smash particles apart in water. In a recent study, the team of researchers, led by McGill professor Jake Barralet, from the faculties of Dentistry and Medicine, found that if particles were coated with phosphate, they could instead bond together into strong agglomerates, about the size of grains of sand. Their results are published in the journal Advanced Materials.

Keeping your balance

Identification of key neurons that sense unexpected motion has significant implications for understanding of motion sickness
Mon, 2013-07-29 11:37

It happens to all of us at least once each winter in Montreal. You’re walking on the sidewalk and before you know it you are slipping on a patch of ice hidden under a dusting of snow. Sometimes you fall. Surprisingly often, you manage to recover your balance and walk away unscathed. McGill University researchers now understand what’s going on in the brain when you manage to recover your balance in these situations. And it is not just a matter of good luck.
