Eating three more portions of dietary fiber a day--say, two pieces of whole grain bread and a bowl of whole grain breakfast cereal--is associated with a lower risk for all cardiovascular diseases and for dying of cancer, diabetes, and respiratory and infectious diseases, a study just published in the BMJ has shown. The study is strong proof that consuming lots of whole grains is good for our health, says first author Dagfinn Aune, a PhD candidate at the Norwegian University of Science and Technology who is currently working at Imperial College, London.

Early-stage breast cancer patients receiving a shorter course of whole breast radiation with higher radiation doses per fraction reported equivalent cosmetic, functional and pain outcomes over time as those receiving a longer, lower-dose per fraction course of treatment, according to researchers from The University of Texas MD Anderson Cancer Center.
Adult stem cells represent a sort of blank clay from which a myriad of different cell and tissue types are molded and as such are of critical importance to health, aging and disease. In tissues that turn over rapidly, such as the intestines, the self-renewing nature of stem cells and their susceptibility to cancer-causing mutations has led researchers to postulate that these cells also act as the cell of origin in cancers. The rarity of adult stem cells relative to their differentiated daughter cells has, however, made them historically difficult to study.
Scientists from ITMO University, the Federal Research and Clinical Centre of Physical-Chemical Medicine and MIPT have developed a software program enabling them to quickly compare sets of DNA of microorganisms living in different environments. The researchers have already suggested exactly how the new program could be applied in practice.
Whether you're Van Gogh or a stick-figure sketcher, a new Drexel University study found that making art can significantly reduce stress-related hormones in your body.
Although the researchers from Drexel's College of Nursing and Health Professions believed that past experience in creating art might amplify the activity's stress-reducing effects, their study found that everyone seems to benefit equally.
A UK research team has discovered that a cell's protective layer acts like a turnstile, allowing proteins to be exported while preventing them from moving back in.
All cells are surrounded by a protective layer - a membrane - which keeps the contents of the cell together and protects it from damage.
However, proteins made inside the cell often need to be exported in order to do their job. For instance, in bacterial adherence, pathogenesis and antibiotic clearance.
A team from the University of Bristol has shed new light on the creatures that inhabited the tropical seas surrounding Britain at the start of the age of the dinosaurs.
Some 210 million years ago, Britain consisted of many islands, surrounded by warm seas. Europe at the time lay farther south, at latitudes equivalent to North Africa today. Much of Europe was hot desert, and at this point was flooded by a great sea - the Rhaetian Transgression.
Light cannot be used to image any structures smaller than half its wavelength - for a long time, this was considered to be the ultimate resolution limit in light microscopy. The development of superresolution microscopy, however, showed that there are certain loopholes to this rule. By imaging individual molecules at different points in time, their exact positions can eventually be combined to one clear picture. In 2014, the Nobel Prize in Chemistry was awarded for this idea.
There may soon be a new way to make molecules to form the basis of pharmaceuticals, fuels, agrochemicals, materials, and an array of other products in our modern life. Chemists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have successfully married chemistry and biology to create reactions never before possible.
DARIEN, IL - A new study of adolescents suggests that obtaining an insufficient amount of sleep increases variability in sadness, anger, energy and feelings of sleepiness. The study also showed that nightly fluctuations in sleep in healthy adolescents predict worse mood the next day, and worse mood any given day largely predicts unusually bad sleep the next night.
URBANA, Ill. - Adding carbon dioxide gas to water, a process similar to making carbonated soda water, could help control the movement and behavior of invasive carp in the Great Lakes basin, according to a recent study.
"This study demonstrates the ability of carbon dioxide to act as a non-physical barrier on a large scale," says University of Illinois researcher Cory Suski. " Work on this topic to date has primarily been performed in small, laboratory studies, and so this work showed the potential for CO2 to be effective at larger scales more relevant to field applications."
Halfway between Hawaii and American Samoa lies a group of small islands and inlets. Among them is Palmyra Atoll, an almost 5-square-mile ring of coral.
The lagoons of Palmyra -- part of the Pacific Remote Islands Marine National Monument -- provide sanctuary for a variety of mobile species including sharks, manta rays and turtles.
Researchers have developed a technique for coating polymer implants with a bioactive film that significantly increases bonding between the implant and surrounding bone in an animal model. The advance could significantly improve the success rate of such implants, which are often used in spinal surgeries. The work was done by researchers at North Carolina State University, the University of Cambridge and the University of Texas at San Antonio.
(PHILADELPHIA) - Research is finally beginning to shed light on some of the reasons that extra weight is difficult to shed permanently. Now, a new study has uncovered another method by which the gut senses how much food a person eats and relays that to the brain. When the gut senses too many calories, a pathway that promotes the feeling of fullness becomes blocked. The new research was published in the journal Nutrition & Diabetes, published by Nature.
In late 2015, former President Jimmy Carter announced that he was free of the metastatic melanoma that had spread to his liver and brain. In addition to surgery and radiation, Carter was treated with an immunotherapy drug, a new approach in cancer treatment that has a promising outlook.
