A study of lead service lines in Flint's damaged drinking water system reveals a Swiss cheese pattern in the pipes' interior crust, with holes where the lead used to be.

The findings—led by researchers at the University of Michigan—support the generally accepted understanding that lead leached into the system because that water wasn't treated to prevent corrosion. While previous studies had pointed to this mechanism, this is the first direct evidence. It contradicts a regulator's claim earlier this year that corrosion control chemicals would not have prevented the water crisis.

The structure of a protein key to the survival and spread of a virus that affects salmon could inform strategies to treat the flu in humans, according to scientists at Rice University.

A mosquito trap that uses a person’s smell combined with warm water and a dark cylindrical shape could transform how the insects are caught in developing countries, say its creators.

Exposure to air pollution early in a pregnancy could increase risk for preterm birth and low birth weight, according to a study led by researchers at NYU School of Medicine, and published on July 27 in Environmental Health Perspectives.

Many images of rural America are food-related—a freshly-baked apple pie cooling on the windowsill, a roadside produce stand brimming with sweet corn and tomatoes, or a Norman Rockwell print showing a family sitting down to dinner. But the reality is that many people in rural America face hunger and don’t always know where their next meal is coming from.

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.
