Michael Mosley wants to find out how much meat is safe to eat, he arrives in Boston to find out the results of research conducted on red meat and processed meat... Taken from Should I Eat Meat?

Every year during the foodless winter months, bears enter their den and lapse into a state of extended dormancy and slumber (called hibernation). For the next 130+ consecutive days they do not drink, eat, defecate, or urinate. Rarely do they die from starvation, dehydration, or poisoning from waste buildup while hibernating. How do bears prepare for this period of starvation coupled with significant weight loss? Bears are not only the champions of winter rest, but are also the undisputed champions of non-stop summer eating. They are constantly on the move during late spring and all summer long into late autumn oftentimes covering great distances over diverse habitats in their incessant search for locally and seasonally available food. In this case study, students learn the basics about bear denning, hibernation energetics, the differences in size of bear home ranges, and the nutritional landscape they must navigate to prepare for the long months of winter inactivity and caloric deprivation. The case is suitable for a wide audience, including majors or non-majors in lower- or upper-level undergraduate courses in environmental science, ecology, biology, or wildlife science.

This case study was developed for an introductory biology course with the goal of integrating content (specifically, structure/function, signaling pathways, and homeostasis) while reinforcing general critical thinking skills and the scientific method (generating hypotheses, evaluating evidence, and making predictions). The case is suitable for a flipped classroom and there are several videos associated with it. The case revolves around an obese two-and-a-half-year-old boy who won't stop eating. Students become familiar with some basic concepts related to obesity and leptin signaling through the videos that they watch before class. They then use class time to work through the case (delivered as an interactive slide show, including several clicker questions) to determine the genetic basis for this child's obesity and possible therapies to manage his weight. The case could also be adapted and expanded to be used in a physiology course to explore the interaction of various hormones that regulate appetite and metabolic rate or in a cell biology class to explore JAK-STAT signaling.

Why do we smell different when we're sick? Why does cheese smell like feet? Why don't vultures get sick from eating rotting meat? Science is filled with stories: some of them are beautiful and some of them are gross. Really gross. Gross Science, a YouTube series hosted by Anna Rothschild, tells bizarre stories from the slimy, smelly, creepy world of science. In this collection, you'll find original short-form videos and DIY experiments from Gross Science, which is produced by NOVA and PBS Digital Studios. Learn about amphibians that eat their mother's skin, strange uses for bacon, how poop can be used to cure an infection, and more gross science topics.

Brain-eating amoebas (Naegleria fowleri) are found in warm freshwater pools around the world, feeding on bacteria. If someone swims in one of these pools and gets water up their nose, the amoeba heads for the brain in search of a meal. Once there, it starts to destroy tissue by ingesting cells and releasing proteins that make other cells disintegrate.

It may sound radical, but it works: Eating peanuts slashes the chance of a peanut allergy, at least in children at high risk of developing one, a much-anticipated study finds. The results are likely to catapult a long-standing theory-that ingesting potential food allergens is a way to prevent allergies-into mainstream medicine. "This is the study," says Rebecca Gruchalla, a specialist in allergy immunology at the University of Texas Southwestern Medical Center in Dallas, who wasn't involved in it. The data, she says, are "just mind-blowing."

4:51 video What's tasty, abundant and high in protein? Bugs! Although less common outside the tropics, entomophagy, the practice of eating bugs, was once extremely widespread throughout cultures. You may feel icky about munching on insects, but they feed about 2 billion people each day (Mmm, fried tarantulas). They also hold promise for food security and the environment. Emma Bryce makes a compelling case for dining on bugs.

Perhaps the biggest misconception is that as long as you lose weight, it doesn't matter what you eat. But it does. Yet being thin and being healthy are not at all the same thing. Being overweight is not necessarily linked with disease or premature death. What you eat affects which diseases you may develop, regardless of whether you're thin or fat.

The bacteria in our guts can break down food the body can't digest, produce important nutrients, regulate the immune system, and protect against harmful germs. And while we can't control all the factors that go into maintaining a healthy gut microbiome, we can manipulate the balance of our microbes by paying attention to what we eat. Shilpa Ravella shares the best foods for a healthy gut.

Organic food has become the fastest-growing sector of the U.S. food industry, with sales that increase by double digits annually. That's a lot of kale flying off the shelves. Buying it makes us feel like we're helping ourselves and the planet. But here's the truth: There are no health benefits from eating organic food. And it is likely worse for the environment.

Massive vines that blanket the southern United States, climbing high as they uproot trees and swallow buildings. A ravenous snake that is capable of devouring an alligator. Rabbit populations that eat themselves into starvation. These aren't horror movie concepts - they're real stories. But how could such situations exist in nature? Jennifer Klos gives the facts on invasive species.

The WHO recently announced that eating too much processed meat can lead to cancer, but what makes processed meat so bad for you?

When you eat something loaded with sugar, your taste buds, your gut and your brain all take notice. This activation of your reward system is not unlike how bodies process addictive substances such as alcohol or nicotine -- an overload of sugar spikes dopamine levels and leaves you craving more. Nicole Avena explains why sweets and treats should be enjoyed in moderation.

Based on a comprehensive analysis of the scientific evidence, as required by the Federal Food, Drug and Cosmetic Act (FD&C Act), the FDA has determined that AquAdvantage Salmon meets the statutory requirements for safety and effectiveness under the FD&C Act. The salmon are safe to eat, the introduced DNA is safe for the fish itself, and the salmon meet the sponsor's claim about faster growth. Because the sponsor has met these requirements, the FDA must approve the application. The FDA has also analyzed the potential environmental impact that an approval of the AquAdvantage Salmon application would have on the quality of the human environment in the United States and has issued its final Environmental Assessment and Finding of No Significant Impact.

Dean Ornish shares new research that shows how adopting healthy lifestyle habits can affect a person at a genetic level. For instance, he says, when you live healthier, eat better, exercise, and love more, your brain cells actually increase.

Yahoo News article 4/30 Published in the journal Nature Communications, the study claims to provide strong evidence that a mother's diet before pregnancy can permanently affect her child's lifelong health by silencing certain genes.

It took about 9,000 years and alterations in six genetic pathways to transform the inedible grass teosinte (left) into the corn we eat today (right). (Center: a first generation hybrid between teosinte and corn)

But did they actually live longer? The answer is yes! The average lifespan of monkeys on a regular diet is approximately 26 years, but the CR monkeys lived on average 3 years longer, a whopping 10 percent increase. The statistics suggest at any point in time, the control monkeys had 2.9 times the rate of death from age-related causes compared to those on a CR diet.

Exposing mice to long periods of light each day led them to put on fat, likely because their energy-burning brown fat wasn't in good shape.  Mice exposed to long periods of light didn't eat more or exercise less than mice that kept to a 12-hour day, but their brown fat activity dropped, researchers reported in PNAS this week (May 11).

You won't see them on your favorite cooking show any time soon, but chimps prefer their food cooked and will bring items to be cooked before they eat them
