Consumption Of Resistant Starch May Protect Against Bowel Cancer

Health News Report

Western diets are typically low in fibre and have been linked with a higher incidence of bowel cancer. Even though Australians eat more dietary fibre than many other western countries, bowel cancer is still the second most commonly reported cancer in Australia with 30 new cases diagnosed every day. Dr David Topping, from CSIRO’s Food Futures Flagship, said this is referred to as ‘the Australian paradox’. “We have been trying to find out why Australians aren’t showing a reduction in bowel cancer rates and we think the answer is that we don’t eat enough resistant starch, which is… more »

Maintain your brain: The secrets to aging success

Health News Report – 1 day ago

Aging may seem unavoidable, but that’s not necessarily so when it comes to the brain. So say researchers in the April 27th issue of the Cell Press journal Trends in Cognitive Sciences explaining that it is what you do in old age that matters more when it comes to maintaining a youthful brain not what you did earlier in life. “Although some memory functions do tend to decline as we get older, several elderly show well preserved functioning and this is related to a well-preserved, youth-like brain,” says Lars Nyberg of Umeå University in Sweden. Education won’t save your brain –… more »

Automated Essay Scoring Systems as Effective as Human Graders

Education Research Report – 1 day ago

A direct comparison between human graders and software designed to score student essays achieved virtually identical levels of accuracy, with the software in some cases proving to be more reliable, a groundbreaking studyhas found. “The demonstration showed conclusively that automated essay scoring systems are fast, accurate, and cost effective,” said Tom Vander Ark, CEO of Open Education Solutions, which provides consulting serves related to digital learning, and co-director of the study. That’s important because writing essays are one important way for students to learn critical … more »

Beware Of Dietary Supplements For Cancer Prevention

Health News Report – 1 day ago

Government regulators and the scientific community should work to ensure that they give clear guidance to the public about dietary supplements and cancer risk, according to a commentary published in the Journal of the National Cancer Institute. Evidence from animal, in vitro and observational studies has suggested that taking dietary supplements may lower cancer risk. However, the small number of randomized controlled studies, the gold standard in evidence-based medicine, has not confirmed this – and some studies have actually shown that supplements may increase cancer risk. Stil… more »

Building muscle without heavy weights

Health News Report – 1 day ago

Weight training at a lower intensity but with more repetitions may be as effective for building muscle as lifting heavy weights says a new opinion piece in Applied Physiology, Nutrition, and Metabolism. “The perspective provided in this review highlights that other resistance protocols, beyond the often discussed high-intensity training, can be effective in stimulating a muscle building response that may translate into bigger muscles after resistance training,” says lead author Nicholas Burd. “These findings have important implications from a public health standpoint because skel… more »

Guidelines say diet, exercise, weight control improve odds after cancer diagnosis

Health News Report – 1 day ago

New guidelines from the American Cancer Society say for many cancers, maintaining a healthy weight, getting adequate physical activity, and eating a healthy diet can reduce the chance of recurrence and increase the likelihood of disease-free survival after a diagnosis. The recommendations are included in newly released Nutrition and Physical Activity Guidelines for Cancer Survivors, published early online in CA: A Cancer Journal for Clinicians. Increasing evidence shows that for many cancers, excess weight, lack of exercise, and poor nutrition increase the risk of cancer recurren… more »

Berries keep your brain sharp

*A new study from Brigham and Women’s Hospital found that certain berries may delay memory decline in older women* Berries are good for you, that’s no secret. But can strawberries and blueberries actually keep your brain sharp in old age? A new study by researchers at Brigham and Women’s Hospital (BWH) finds that a high intake of flavonoid rich berries, such as strawberries and blueberries, over time, can delay memory decline in older women by 2.5 years. This study is published by Annals of Neurology, a journal of the American Neurological Association and Child Neurology Society, … more »

Number Line Is Learned, Not Innate Human Intuition

Education Research Report – 2 days ago

Tape measures. Rulers. Graphs. The gas gauge in your car, and the icon on your favorite digital device showing battery power. The number line and its cousins — notations that map numbers onto space and often represent magnitude — are everywhere. Most adults in industrialized societies are so fluent at using the concept, we hardly think about it. We don’t stop to wonder: Is it “natural”? Is it cultural? Now, challenging a mainstream scholarly position that the number-line concept is innate, a study suggests it is learned. The study, published in PLoS ONE April 25, is based on e… more »

Women: Mental Stress=Greater Risk For Heart Disease

Health News Report – 2 days ago

Coronary artery disease continues to be a major cause of death in the U.S., killing hundreds of thousands of people per year. However, this disease burden isn’t evenly divided between the sexes; significantly more men than women are diagnosed with coronary artery disease each year. The reasons behind this difference aren’t well defined. Though some studies have shown that men’s hearts become more constricted than women’s during exercise, letting less blood flow through, women are more likely than men to have symptoms of heart trouble after emotional upsets. Searching for the reas… more »

Splenda Causes Cancer Concern

Following the discovery in a new study that mice have a higher risk of developing cancer after eating the popular British-made low-calorie artificial sweetener sucralose (Splenda), a leading cancer scientist calls for urgent research. Dr. Morando Soffritti, director of the Ramazzini Institute in Bologna, Italy will present the findings of the study for the first time at the Childhood Cancer 2012 conference in London.

Colon Cancer Survival Improves With Aspirin

Health News Report – 3 days ago

Colon cancer patients who take aspirin regularly shortly after diagnosis tend to live longer, researchers from Leiden University Medical Centre, the Netherlands, reported in the British Journal of Cancer. The authors explain that NSAIDs (non-steroid anti-inflammatory drugs) have been known to have a preventive role with regards to colorectal cancer, and in particular, aspirin. Recently, some studies and experts have suggested that regular aspirin may have a therapeutic role too. However, studies so far have not been conclusive. Dr Gerrit-Jan Liefers and team set out to determine… more »

Strong daylight prevents heart attacks

Health News Report – 3 days ago

“A new study suggests that strong light, or even just daylight, might ease the risk of having a heart attack or suffering damage from one,” says Tobias Eckle, MD, PhD, an associate professor of anesthesiology, cardiology, and cell and developmental biology at the University of Colorado School of Medicine. “For patients, this could mean that daylight exposure inside of the hospital could reduce the damage that is caused by a heart attack.” What’s the connection between light and a myocardial infarction, known commonly as a heart attack? The answer lies, perhaps surprisingly, in … more »

Samaritan’s Temple: History and New Findings
Archaeology News Report – 3 days ago

The original article from which these excerpts are drawn is quite anti-Semitic. But the story is quite interesting nonetheless: The archaeologist Yitzhak Magen has been digging on the windswept summit of Mount Gerizim. His findings, which have only been partially published, are a virtual sensation: As early as 2,500 years ago, the mountain was already crowned with a huge, dazzling shrine, surrounded by a 96 by 98-meter (315 by 321-foot) enclosure. The wall had six-chamber gates with colossal wooden doors. At the time, the Temple of Jerusalem was, at most, but a simple structur… more »

Found within the City of David National Park, which is situated within the most ancient part of Jerusalem, the scarab is attributed to Egypt’s 19th Dynasty, a period of Egyptian hegemony over the city that was actually a Jebusite settlement at the time. The Jebusites were a tribe of Canaanites that built and developed Je… more »
