Birds originated from a group of small, meat-eating theropod dinosaurs called maniraptorans sometime around 150 million years ago. Recent findings from around the world show that many maniraptorans were very bird-like, with feathers, hollow bones, small body sizes and high metabolic rates.

Last year, more than 800 Chinese students crossed the Pacific to attend 91˿Ƶ, making China the third largest source of international students for the University, behind only the United States and France.  And that number is growing every year; in fact, it has more than doubled since 2007.

The brown, smog-filled skies that engulf Beijing have earned China a poor reputation for environmental stewardship. But a study by an international and interdisciplinary team of environmental scientists, including 91˿Ƶ’s Brian Robinson, has found that a government-run clean water program is providing substantial benefit to millions of people in the nation's capital.

A team of University of Montreal and 91˿Ƶ researchers have devised a method to identify how signaling molecules orchestrate the sequential steps in cell division. In an article published online today in the Proceedings of the National Academy of Sciences, the scientists explain how they could track the relationship between signaling molecules and their target molecules to establish where, when and how the targets are deployed to perform the many steps necessary to replicate an individual cell’s genome and surrounding structures.

Nanoscale “cages” made from strands of DNA can encapsulate small-molecule drugs and release them in response to a specific stimulus, 91˿Ƶ researchers report in a new study. 

The research, published online Sept. 1 in Nature Chemistry, marks a step toward the use of biological nanostructures to deliver drugs to diseased cells in patients. The findings could also open up new possibilities for designing DNA-based nanomaterials.

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 91˿Ƶ and Concordia University, however, these common sleep disturbances may one day be put to bed.

Researchers at 91˿Ƶ 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.

Research from 91˿Ƶ 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 91˿Ƶ’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.

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.

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.

Researchers at 91˿Ƶ 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 91˿Ƶ 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.
