By Marsha Lewis, Inside Science  – The statistics are shocking. Almost half of all Americans live with one or more risk factors for a heart attack.

Now, bioengineers at the Christman Lab at the University of California, San Diego have created a material that could repair and even reverse the damage done by a heart attack.

"A heart attack is a single event where the blood supply is blocked to that downstream tissue," said Karen Christman, a bioengineer at UCSD. When the tissue is deprived of the blood it needs, it becomes damaged.

By Sara Rennekamp, Inside Science -- Last week's deadly derailment that sent an Amtrak Northeast Regional train careening off its tracks has many people asking how such a tragedy could happen.

Brian Owens, Inside Science - Habitual gamblers are more likely to believe they see patterns in random sequences of events, and to act on that belief, than the general population, according to new research.

By Sara Rennekamp, Inside Science  -- News broke this week that the company behind the popular Kind line of snack bars received a warning letter from the Food and Drug Administration.

Their offense? Not labeling the bars according to FDA rules -- primarily due to slapping a "healthy" label on a product that did not meet the FDA standards for healthy.

Mammals, birds, reptiles, amphibians, fish, even you are a vertebrate. And now for the first time, scientists from around the world are coming together to study them on a molecular level.

"The Genome 10k Project is our first look at vertebrate animal life," said David Haussler, a biomolecular engineer at the University of California, Santa Cruz. "We're trying to get at least 10,000 species represented in our genome collection," he said.

By Sara Rennekamp, Inside Science - Is your wine vegan? It seems like an odd question: wine is made of grapes, grapes fall solidly under the "not an animal product" label, therefore it would seem that wine is a vegan-friendly beverage.

However, many people who adhere to a vegan diet refrain from consuming any food or drink that is processed using animal products as well as the animal products themselves. Unfortunately for vegans, some wines are processed using animal products.

The culprit: a process called fining.
