Equivalent of 183,000 football fields of nonagricultural land identified in study aiming to ease competition between farmers, conservationists, and energy companies.

University of Saskatchewan researcher Scott Adams has proven that MELODY telerobotic sonography, a French-developed system that allows doctors to do long distance ultrasound imaging, is feasible for abdominal and prenatal imaging. Adams is part of the first research team to test this technology in North America.

“The new telerobotic system could help save time and money. Patients may get earlier diagnoses while reducing the strain on major referral hospitals,” said U of S medical imaging professor Paul Babyn, Adams’s supervisor along with surgery professor Ivar Mendez. 

It’s the kind of thing you might lose sleep over.

How will humans survive serious infections in the future if we’re running out of tools today to fight them? Antibiotic resistance among disease-causing bacteria is of global concern, as some last-resort drugs can no longer cure common illnesses such as urinary tract infections. 

A University of Victoria molecular biologist has gained new insights into how environmental contaminants may disrupt thyroid systems, discovered while assembling the genome of the North American bullfrog.

Caren Helbing’s findings could help explain the mechanisms of early development and metamorphosis, as well as how environmental contaminants cause thyroid-related diseases and malfunctions.

Imagine a scenario where a volcano is about to erupt and you are responsible for deciding what to do next. Who should be alerted and who needs to be evacuated? Where and when might lava start flowing? How dangerous will the gas and ash emissions be?

This is what Earth Sciences 421 students experienced during a five-hour volcano simulation exercise in early December.

An imbalance between the trends in two common air pollutants is unexpectedly triggering the creation of a class of airborne organic compounds not usually found in the atmosphere over urban areas of North America, according to a new study from Caltech.

HIV, dengue, papillomavirus, herpes and Ebola – these are just some of the many viruses that kill millions of people every year, mostly children in developing countries. While drugs can be used against some viruses, there is currently no broad-spectrum treatment that is effective against several at the same time, in the same way that broad-spectrum antibiotics fight a range of bacteria. But researchers at EPFL's Supramolecular Nano-Materials and Interfaces Laboratory – Constellium Chair (SUNMIL) have created gold nanoparticles for just this purpose, and their findings could lead to a broad-spectrum treatment. Once injected in the body, these nanoparticles imitate human cells and “trick” the viruses. When the viruses bind to them – in order to infect them – the nanoparticles use pressure produced locally by this link-up to “break” the viruses, rendering them innocuous. The results of this research have just been published in Nature Materials.

As cars become more fuel-efficient, less heat is wasted in the exhaust, which makes it harder to clean up the pollutants that are emitted. But researchers have recently created a catalyst capable of reducing pollutants at the lower temperatures expected in advanced engines. Their work, published this week in Science magazine, a leading peer-reviewed research journal, presents a new way to create a more powerful catalyst while using smaller amounts of platinum, the most expensive component of emission-control catalysts.

NASA's Aqua satellite provided infrared imagery of Tropical Storm Kai-Tak that revealed the western side of storm had moved into the southern and central Philippines. Infrared data revealed very cold cloud top temperatures with the potential for heavy rainfall.

Digital screen use is a staple of contemporary life for adults and children, whether they are browsing on laptops and smartphones, or watching TV. Paediatricians and scientists have long expressed concerns about the impact of overusing technology on people’s wellbeing. However, new Oxford University research suggests that existing guidance managing children’s digital media time may not be as beneficial as first thought.
