Surgeons were able to identify and remove a greater number of cancerous nodules from lung cancer patients when combining intraoperative molecular imaging (IMI) – through the use of a contrast agent that makes tumor cells glow during surgery – with preoperative positron emission tomography (PET) scans. The study from the Abramson Cancer Center at the University of Pennsylvania (ACC) is the first to show how effective the combination of IMI with the tumor-glowing agent can be when combined with traditional PET imaging. Researchers published their findings today in Annals of Surgery.

Whey protein supplements aren’t just for gym buffs according to new research from McMaster University. When taken on a regular basis, a combination of these and other ingredients in a ready-to-drink formula have been found to greatly improve the physical strength of a growing cohort: senior citizens.

The deterioration of muscle mass and strength that is a normal part of aging –known as sarcopenia—can increase the risk for falls, metabolic disorders and the need for assisted living, say researchers.

A new analysis projects that inaction on climate change could lead to tens of thousands more heat-related deaths annually in U.S. metropolitan areas within a few generations.

A lonely bird call breaks my concentration and I glance upward. Where glacier-topped mountains should be filling the horizon, instead my view is obscured by a strange orange haze. Even the bright sun has given up. It seems to float in the sky as a faint pink ball.

I am a field ecologist working east of the Denali mountain range in Alaska, but the postcard-worthy view of my sites today is obscured by smoke drifting across the border from wildfires burning throughout British Columbia. I have been studying boreal wildfires for years and have a strong understanding of the importance of fire to the boreal forest of Canada.

These hot summer days may prompt you to cut back on outdoor activity – just as cold weather during the winter can be a reason to sit on your sofa.

A research team at the University of Regina, led by Dr. Katya Herman, Assistant Professor in the Faculty of Kinesiology and Health Studies, is looking into how the seasons affect physical activity.

A new study indicates that cancer patients and survivors have a ready weapon against fatigue and “chemo brain”: a brisk walk.

Researchers at the University of Illinois, along with collaborators at Digital Artefacts in Iowa City, Iowa, and Northeastern University in Boston, looked at the association between physical activity, fatigue and performance on cognitive tasks in nearly 300 breast cancer survivors.

Mindfulness training and hypnotic suggestion significantly reduced acute pain experienced by hospital patients, according to a new studypublished in the Journal of General Internal Medicine.

New research is challenging the age-old adage that money can’t buy happiness.

The study, led by researchers at the University of British Columbia and Harvard Business School, suggests that using money to buy free time— such as paying to delegate household chores like cleaning and cooking— is linked to greater life satisfaction.

A new way of producing the seasonal flu vaccine could speed up the process and provide better protection against infection.

The first in-car measurements of exposure to pollutants that cause oxidative stress during rush hour commutes has turned up potentially alarming results. The levels of some forms of harmful particulate matter inside car cabins was found to be twice as high as previously believed.

Most traffic pollution sensors are placed on the ground alongside the road and take continuous samples for a 24-hour period. Exhaust composition, however, changes rapidly enough for drivers to experience different conditions inside their vehicles than these roadside sensors. Long-term sampling also misses nuanced variabilities caused by road congestion and environmental conditions.
