    Eating too much protein could be as dangerous as smoking for middle-aged people, a study has found. Research which tracked thousands of adults for nearly 20 years found that those who eat a diet rich in animal protein are four times more likely to die of cancer than someone with a low-protein diet. The risk is nearly as high as the danger of developing cancer from smoking 20 cigarettes each day. Previous studies have shown a link between cancer and red meat, but it is the first time research has measured the risk of death associated with regularly eating too...
  • 7 Insects You'll Be Eating in the Future

    Food of the future Credit: Chad Zuber | Shutterstock.com As the human population continues to inch closer to 8 billion people, feeding all those hungry mouths will become increasingly difficult. A growing number of experts claim that people will soon have no choice but to consume insects. As if to underscore that claim, a group of students from McGill University in Montreal has won the 2013 Hult Prize, for producing a protein-rich flour made from insects. The prize gives the students $1 million in seed money to begin creating what they call Power Flour. "We will be starting with grasshoppers,"...

    That chicken wing you're eating could be as deadly as a cigarette. In a new study that tracked a large sample of adults for nearly two decades, researchers have found that eating a diet rich in animal proteins during middle age makes you four times more likely to die of cancer than someone with a low-protein diet -- a mortality risk factor comparable to smoking. "There's a misconception that because we all eat, understanding nutrition is simple. But the question is not whether a certain diet allows you to do well for three days, but can it help you survive...

    Incredible Microprocessor Protein Acts as Genome Guardian by Jeffrey Tomkins, Ph.D. * Researchers recently studied a highly sophisticated cellular machine that acts as a guard for the genome against harmful mutations and that evolution cannot explain.1 Humans have two sets of 23 chromosomes, and a mutational deletion in chromosome 22 causes a disease called DiGeorge syndrome in which heart and immune system defects occur, in addition to learning difficulties, mental retardation, and psychiatric disorders. The deletion eliminates a protein and stops the formation of a key piece of cellular machinery called a "microprocessor." The microprocessor is actually a working complex...

    Researchers have reconstructed the structure of 4-billion-year-old proteins. The primeval proteins, described today (Aug. 8) in the journal Structure, could reveal new insights about the origin of life, said study co-author José Manuel Sanchez Ruíz, a physical chemist at the University of Granada in Spain. Exactly how life emerged on Earth more than 3 billion years ago is a mystery. Some scientists believe that lightning struck the primordial soup in ammonia-rich oceans, producing the complex molecules that formed the precursors to life. Others believe that chemical reactions at deep-sea hydrothermal vents gave rise to cell membranes and simple cellular pumps....

    The scientists discovered that the ceramide-1 phosphate transport protein (CPTP) regulates levels of biologically active lipids, which are molecules such as fatty acids that often play a role in cell signaling. They found that CPTP's main function is to transport ceramide-1-phosphate (C1P), a lipid that helps regulate cell growth, survival, migration and inflammation. Specifically, C1P increases the production of pro-inflammatory eicosanoids – powerful signaling molecules that contribute to chronic inflammation in diseases such as cancer, asthma, atherosclerosis and thrombosis – and the discovery of CPTP sheds a light on the cellular mechanisms that contribute to these diseases. "We may have...

    Researchers at UT Southwestern Medical Center report the identification of a new cellular source for an important disease-fighting protein used in the body's earliest response to infection. The protein interferon-gamma (IFN-γ) keeps viruses from replicating and stimulates the immune system to produce other disease-fighting agents. Neutrophils, the newly identified cellular source of the protein, are the major component of the pus that forms around injured tissue. The researchers also report that the neutrophils appear to produce IFN-γ through a new cellular pathway independent of Toll-like receptors (TLRs): the body's early warning system for invasion by pathogens. This finding indicates that...

    Not long ago, quinoa was just an obscure Peruvian grain you could only buy in wholefood shops. We struggled to pronounce it (it's keen-wa, not qui-no-a), yet it was feted by food lovers as a novel addition to the familiar ranks of couscous and rice. Dieticians clucked over quinoa approvingly because it ticked the low-fat box and fitted in with government healthy eating advice to "base your meals on starchy foods". Adventurous eaters liked its slightly bitter taste and the little white curls that formed around the grains. Vegans embraced quinoa as a credibly nutritious substitute for meat. Unusual among...

    We've seen promising moves towards developing a universal or near-universal influenza vaccine, but researchers at the Donald P. Shiley BioScience Center have taken a different tack to ward of the crafty virus. Although the flu virus actively keeps the immune system from detecting it for a few days, giving it time to gain a foothold, the researchers have found that a powerful synthetic protein, known as EP67, can kick start the immune system so that it reacts almost immediately to all strains of the virus. Previously, EP67 had primarily been used to help activate the immune response by being added...

"The question is what should we be using taxpayer funds to purchase," the Bakersfield Democrat said Tuesday. "In my opinion, we should be focusing on what people need, not what they want." Those needs include foods found in the traditional food pyramid, he said, including breads and cereals, meats, beans, nuts, dairy products and other protein sources, and lots of fruits and vegetables. Rubio's idea is not yet an official Senate bill. But...

    The South Beach Diet produces rapid weight loss without counting carbs, fats, or calories. It started out simply enough. Arthur Agatston, MD, a cardiologist, decided to develop an eating plan that would improve the cholesterol and insulin levels of his patients with heart disease. Now, the South Beach diet has grown into something much bigger. That's because the plan Agatston created not only improves cholesterol and insulin levels, but it also has helped many people lose weight. "We've had people lose anywhere from five to 100 pounds on the diet," says Agatston, who is director of the Mount Sinai Cardiac...

I’m delighted to see the much-awaited dietary guidelines of the Department of Health and Human Services (HHS) and the United States Department of Agriculture (USDA). A close look at the recommendations released last week shows how closely these recommendations reflect our efforts to raise carbohydrate awareness and emphasize the importance of weight management.

    Genetic changes that apparently allow humans to live longer than any other primate may be rooted in a more carnivorous diet. These changes may also promote brain development and make us less vulnerable to diseases of aging, such as cancer, heart disease and dementia. These key differences in lifespan may be due to genes that humans evolved to adjust better to meat-rich diets, biologist Caleb Finch at the University of Southern California in Los Angeles suggested. The oldest known stone tools manufactured by the ancestors of modern humans, which date back some 2.6 million years, apparently helped butcher animal bones....

    Long life may stem from a proper imbalance of dietary nutrients. A new study in fruit flies suggests that the life-extending properties of caloric restriction may be due not only to fewer calories in the diet, but also to just the right mix of protein building blocks, called amino acids. The study, published online December 2 in Nature, may help explain some of the health benefits of restricted-calorie diets. Coupled with other data, the new study should prompt researchers to reevaluate whether it is calorie count or the nutrient composition of a diet that is most important for regulating lifespan...

    We're often interested in comparing things--predicting a known difference is a good way to test our methods. Then, once we're pretty confident that things work, we want to predict ways to change the way proteins interact. Changing a system in a defined way is both a good tool for biological insight and the basis for a lot of medical treatments. In this particular case, we're interested in the "selectivity" of ligand binding by a protein: the protein is known to bind one small molecule ("ligand") much better than another. So project 3903/3905 is a pair of projects comparing the protein-small...

They speculate that variations in the genes coding for Atp7a, as well as other proteins of copper homeostasis, could partially account for differences in thinking among individuals. Using rat and mouse nerve cells to study the role of copper in the brain, the researchers found that the Atp7a protein shuttles copper to...

    DVDs coated with a layer of protein could one day hold so much information that storing data on your computer hard drive will be obsolete, says a US-based researcher. He says that the protein layer, made from tiny genetically altered microbe proteins, could allow DVDs and other external devices to store terabytes of information. Professor V Renugopalakrishnan of the Harvard Medical School in Boston reported his findings at the International Conference on Nanoscience and Nanotechnology in Brisbane this week. "What this will do eventually is eliminate the need for hard drive memory completely," he says. Renugopalakrishnan says high-capacity storage devices...

    REGULAR meals of mammoth meat helped some early human tribes to expand more quickly than their largely vegetarian contemporaries, according to a genetic study. Human populations in east Asia about 30,000 years ago developed at dramatically different rates, following a pattern that appears to reflect the availability of mammoths and other large game. In the part of the region covering what is now northern China, Mongolia and southern Siberia, vast plains teemed with mammals such as mammoths, mastodons and woolly rhinoceroses and the number of early human beings grew between 34,000 and 20,000 years ago. Further south, where the terrain...

    A CUSTOMER says she found a dead frog in a pre-mixed Caesar salad bought from a Brisbane supermarket. Julie Lumber, of Springfield in Brisbane's west, today said she was preparing for a barbecue when the green intruder dropped out of a Caesar salad "with the works" bought from Coles at the weekend. "I opened up the bag and the frog fell out on the side of the plate. "I just went 'oh my god' and then we had a laugh about it. "I couldn't stomach French food with the frogs legs and snails and I wasn't about to try it...
  • Gene turn-off makes meek mice fearless

    Deactivating a specific gene transforms meek mice into daredevils, researchers have found. The team believe the research might one day enable people suffering from fear – in the form of phobias or anxiety disorders, for example – to be clinically treated. The research found that mice lacking an active gene for the protein stathmin are not only more courageous, but are also slower to learn fear responses to pain-associated stimuli, says geneticist Gleb Shumyatsky, at Rutgers University in New Jersey, US. In the experiments, the stathmin-lacking mice wandered out into the centre of an open box, in defiance of the...
  • Stanford Study Reveals Protein's Jekyll-and-Hyde Role In Cancer Growth

    STANFORD, Calif. - Tumor-suppressor proteins work to inhibit tumor growth in our bodies and when they win, they spare us a battle with cancer. But one such protein, menin, appears to have a split personality. Though menin is well-known for its ability to suppress endocrine tumors, researchers at Stanford University School of Medicine have discovered that it is also a key player in the development of some forms of acute leukemia. The researchers, who made the discovery in working with mouse cells, say this is the first time a tumor-suppressor protein has been found to have such a dramatic dual...

    Randall Robinson, an activist and Harvard-educated lawyer whose past activities include founding the TransAfrica organization, encouraging black Americans to sue for reparations, and then loudly emigrating in protest from the U.S. to the Caribean island of St. Kitts, now claims that black Hurricane victims are "eating corpses to survive." A quick scan of major news networks and a Google search on the phrase "hurricane victims eating corpses to survive" uncovers absolutely no support for this outrageous claim. While that's hardly the final word when it comes to proof, it's more evidence than Robinson offers for his bizarre claim. Ordinarily, I...

    WASHINGTON (AP) -- While a breakthrough for humans could be years away, a new study in mice suggests some memory recovery may be possible in the early stages of Alzheimer's disease. "There basically are two prongs and we need to deal with both," said lead researcher Karen Ashe, a University of Minnesota neurologist. "What we're showing is that there are neurons which are affected (by Alzheimer's) but not dead." New research shows a mutant protein named tau is poisoning brain cells, and that blocking its production may allow some of those sick neurons to recover. It worked in demented mice...

    http://www.rettsyndrome.org/ My daughter Gabriella was diagnosed with Rett syndrome today. The two links explain what it is technically better than I can. The symptoms are regressive. They begin rapidly regressing at age 2 my daughter is 20 months. After regression their is little to no motor skills and communication along with severe retardation. This all seems to be caused by lack of a protein called mecp2. They are beginning to experiment on mice. Knowing the FDA that means many years till treatment comes out. Can anyone answer these questions. Is it true that protein we eat is broken down into...

    Pet store animals cooked in school Fri Jan 21 2005 08:35:35 ET A Guinea pig and rabbit purchased from a Geauga County pet store ended up on plates at a Cleveland area high school. A 16-year-old student skinned and cooked the animals during a living skills class on Wednesday, prompting student and parent complaints to the Thompson Township Police Department and Geauga Humane Society. Officials at both agencies said they are investigating. Friday editions of the CLEVELAND PLAIN DEALER detail how the incident may warrant animal cruelty charges. Geauga Humane Officer Sarah Westman said it's illegal to needlessly kill "companion...

    San Diego scientists have identified a protein in embryonic stem cells that helps weed out mutations as the cells proliferate. Its action may protect a developing embryo from DNA damage that could lead to cancer later in life. The protein is called p53. The researchers, studying embryonic stem cells taken from mice, found that p53 prompts defective stem cells to begin changing into specific types of cells in the body. These defective cells started to show characteristics of neuron cells. Having crossed that threshold, they lost their ability to replicate indefinitely and pass along the mutations. "What we discovered is...

    Tumor-Starving Protein Identified By Karen Pallarito HealthDay Reporter FRIDAY, June 18 (HealthDayNews) -- Researchers in Colorado say they have identified a protein that thwarts the growth of new blood vessels that feed and enlarge tumors. The protein, called fibulin-5, occurs naturally in the body, but researchers say a slightly altered version proved even more effective in arresting blood vessel growth. The protein works by choking off the nutrient and oxygen supply to tumors, preventing the cancer from growing and spreading to other parts of the body. Researchers believe it could one day be developed as a drug to treat cancer...
