Researchers have found many of the components required for a complex eye in a single-celled organism, providing insight into the evolutionary origins of the eye. The findings show how a complex system can evolve in a simple organism. The research team examined warnowiids, a single-celled organism, and found that they have ocelloids, an eye-like structure […]
Living near trees leaves people feeling healthier
A new study of 13,000 residents of Toronto, suggests that living in a neighbourhood with more (and or larger) trees leads people to report feeling healthier. The research team used Toronto tree density data and combined this information with a self-reporting questionnaire of general health perception and certain medical conditions including heart disease, stroke and […]
Community based HIV prevention programs save $5 in treatment costs for every $1 spent
Community based HIV prevention programs helped stop 16,672 HIV infections between 1987 and 2011, saving the health care system approximately $6.5 billion. Researchers found that every dollar invested into community based HIV prevention programs saved approximately five dollars in provincial healthcare costs. The researchers used Ontario HIV surveillance reports to estimate the number of HIV […]
New species of horned dinosaur provides insight into Triceratops family evolution
A new species of horned dinosaur discovered in southern Alberta provides new information about the evolution of the Triceratops family of dinosaurs, the Ceratopsidae. The new species, Wendiceratops pinhornensis, is identified by 184 bones from at least four individuals. The Wendiceratop is an early species of horned dinosaur, living alongside the Albertaceratops, approximately 79 million […]
Visualizing chronic obstructive pulmonary disease using CT and MRI scans
Treatment for patients suffering from mild-to-moderate chronic obstructive pulmonary disease (COPD) could be improved through the use of magnetic resonance imaging (MRI) and computed tomography (CT) according to new research. Researchers found that both MRI and CT measurements helped explain symptoms in the patients that were unable to be explained using traditional methods alone. The […]
Comparing current and reduced carbon emissions shows benefit for the ocean
Researchers compared the effects of two different carbon emissions trajectories and found that reducing emissions to levels required to meet the Copenhagen Accord shows benefits in many areas for the world’s oceans. The research team found that if carbon emissions are mitigated the oceans will be cooler and less acidic. However if carbon emissions maintain […]
Traffic-related air pollution during pregnancy is a likely cause of asthma
Children exposed to high levels of traffic-related air pollution before they are born are more likely to suffer from asthma as children according to a study of Toronto neighbourhoods. The study also found that children in close proximity to high-traffic areas are more likely to suffer from asthma. Researchers analyzed the health and residential records […]
CT scanning for cancer redundant in blood clot patients
Computerized tomography scans, or CT scans, do not improve cancer detection rates, or shorten the time to diagnosis, in patients with unexplained blood clots in the lungs or legs. Previous studies suggest that up to 10 per cent of patients suffering from venous thromboembolism, blood clots in the lungs or legs, will be diagnosed with […]
Unnecessary imaging common among breast cancer patients
Most women diagnosed with early-stage breast cancer are given imaging tests to look for distant growths, despite official guidelines according to a new study. The research team found that over 79 per cent of women with stage I breast cancer, and over 92 per cent with stage II, received imaging tests despite having a less than two […]
Completing the puzzle of arthropod evolution
Newly discovered fossils from the Burgess Shale region are providing scientists with evidence of the evolutionary history of arthropods, a group including insects, spiders and crustaceans. The fossils have also allowed scientists to gather a complete picture of what Hallucigenia, an arthropod existing 508 millions years ago, looked like. The new fossils show that Hallucigenia had […]
Thirty-year recovery of mollusc communities after nuclear tests on a French Polynesian atoll
A 30-year study on a Pacific atoll used for nuclear testing shows that all reefs developed a community composition quite different from that before the tests as the result of random settlement of larvae from the open ocean. Fangataufa atoll located in south-central Pacific (French Polynesia) has been used as a nuclear testing site for […]
The secrets of the Serengeti
Over 300,000 photographs of wild animals in Serengeti National Park, Tanzania have been cataloged and should provide data for future ecological research and educational projects. The photographs were of 40 separate species including lions, zebras, honey badgers and the rare zorilla and aardwolf. Between June 2010 and May 2013 225 camera traps gathered pictures over […]
Genetics links creativity to psychosis
Creativity and psychiatric disorders, such as schizophrenia and bipolar disorder, share genetic roots according to a new study. Researchers analyzed genetic data from over 150,000 Icelanders who were healthy, or had been diagnosed with schizophrenia or bipolar disorder. They found that the same genetic variants associated with increased risk of mental disorders also predicted whether […]
Leaky pipes can lead to water contamination
Underground water pipes can not only leak water but in certain circumstances suck in surrounding and potentially contaminated water. New research shows that while pressure in water mains typically forces water out through the leaks, when the pressure drops, pipes start to suck in groundwater. Any contaminants can then travel throughout the water main network. […]
Anti-smoking legislation reduced children’s hospital admissions in Britain
Smoking legislation reduced child hospital admissions by 11,000 each year in England. Researchers analyzed the the British Hospital Episode Statistics database to analyze over 1,500,000 general hospital admissions for children aged from 0 to 14 years, between 2001-2012 from across England. They found that the legislation resulted in an immediate decline in admissions for lower […]
New species of horned dinosaur found in Alberta
Bones found 10 years ago along the Oldman River in Alberta belonged to a new species of horned dinosaur. This is the first time an horned dinosaurs species has been discovered in Alberta. According to a new study, this dinosaur is similar in many respects to Triceratops, except that its nose horn is taller and the […]
