The world's biggest study offering healthy eating and exercise advice to pregnant women who are overweight or obese has shown a significant reduction in the number of babies born over 4kg (8.8 pounds) in weight. The LIMIT Study, led by researchers from the University of Adelaide's Robinson Institute and the Women's and Children's Hospital, involved more than 2200 pregnant women from 2008-2011. In the first major results from the LIMIT Study, published this week in the British Medical Journal, the researchers say that providing advice and assistance to adopt a healthy ...

Americans don't like to talk about social class. But new research from Northwestern and Stanford universities suggests that, at least in college and university settings, they should do just that. An upcoming article in "Psychological Science" describes a novel one-hour intervention that closed by 63 percent the persistent academic achievement gap between first-generation college students and continuing-generation students. (Continuing-generation students are defined as those with at least one parent with a four-year college degree.) The key to the one-time intervention's ...

BOSTON – Dr. Raquell Holmes, an assistant research professor at Boston University's Center for Computational Science, will be a featured presenter at the 2014 annual meeting of the American Association for the Advancement of Science in Chicago, February 15, 2014. Dr. Holmes will participate in a panel session titled, "Improvisation for Scientists: Making a Human Connection" on February 16, 2014 at 9:15 am. Efforts to "communicate science" have been a rallying cry from governmental agencies, elected officials and citizens in need of accurate and accessible information ...

February 14, 2014 - Knowledge is power, yet new research suggests that a person's appearance alone can trump knowledge. First impressions are so powerful that they can override what we are told about people. A new study found that even when told whether a person was gay or straight, participants generally identified the person's sexual orientation based on how they looked – even if it contradicted the facts presented to them. "We judge books by their covers, and we can't help but do it," says Nicholas Rule of the University of Toronto. "With effort, we can overcome this ...

ATLANTA – February 14, 2014—While new and better treatments have improved the odds of survival for patients diagnosed late stage colorectal cancer, that progress has been largely confined to non-Hispanic whites and Asians and those under age 65, according to a new study. American Cancer Society researchers led by Helmneh Sineshaw, M.D., MPH, find there have been no significant increases in survival rates for Hispanics and non-Hispanic blacks with metastatic colon cancer. The study, appearing in the January issue of Cancer Causes and Control, concludes that the findings ...

Crabs -- those sometimes pesky, hard-shelled beachcombers -- are a highly diverse animal, with some 7,000 species found in oceans, lakes and on land, varying in size from the diminutive pea crab (millimeters) to the giant 4 meter-wide Japanese spider crab. Chu, et.al., have constructed the most complete and extensive dataset to date. Their recalibrated crab gene tree using DNA and mitochondrial sequences from 140 species and 58 crab families provides some new important insights into the timing and diversity of crab evolution. The research team's estimates confirm the ...

For the ancient ancestors of plants and animals, a partnership with other microbes was once formed during an endosymbiotic event to give rise to eukaryotes. Plants and animals, over billions of years of trial and error, made efficient use of different energy sources in the environment, namely carbon dioxide and oxygen. In the advanced online edition of Molecular Biology and Evolution, authors Maurino, et. al., explore the evolution of a family of enzymes, called 2-hydroxy acid oxidase, or 2-HAOX, that break down fats in both plant and animals. They wanted to test and ...

This news release is available in German. Spinach looks nothing like parsley, and basil bears no resemblance to thyme. Each plant has a typical leaf shape that can differ even within the same family. The information about what shape leaves will be is stored in the DNA. According to researchers at the Max Planck Institute for Plant Breeding Research in Cologne, the hairy bittercress (Cardamine hirsuta) has a particular gene to thank for its dissected leaves. This homeobox gene inhibits cell proliferation and growth between leaflets, allowing them to separate from each ...

How do our brains combine information from the external world (sensory stimulation) with information on our internal state such as hunger, fear or stress? NERF-scientists demonstrate that the habenula, a specific part in our brain consisting of neural circuits, acts as a gate for sensory information, thus regulating behavior in response to external stimuli. Emre Yaksi (NERF – VIB/imec/KU Leuven): "Our brain has high levels of spontaneous activity, even in the absence of sensory stimulation. We think that this spontaneous neural activity in combination with sensory stimulation ...

In recent years, the 1.5 kilos of bacteria that live inside our bodies, mainly in the gut, have proven their crucial importance for our healthy functioning. Beyond their more obvious role in digestion, they are also involved, for example, in the development of the immune system and the neuronal system, and in the onset of certain diseases. Three leading European researchers on the gut microbiome will share their recent findings on the relations between gut flora and obesity, diabetes, and cardio-metabolic diseases in general. Links Between Human Gut Microbiota and Metabolic ...

Understanding the region of interstellar space through which the solar system travels is no easy task. Interstellar space begins beyond the heliosphere, the bubble of charged particles surrounding the sun that reaches far beyond the outer planets. Voyager 1 has crossed into this space, but it's difficult to gain a complete global picture from measurements in only one direction. Spacecraft data in the past five years from near Earth and cosmic ray observations have painted a better picture of the magnetic system that surrounds us, while at the same time raising new questions. ...

New research from Karolinska Institutet in Sweden shows that the final stage of the normal inflammatory process may be disrupted in patients with Alzheimer's disease. A study published in the journal Alzheimer's & Dementia shows that levels in the brain and cerebrospinal fluid of the molecules necessary for tissue recovery through the clearance of harmful inflammatory substances are lower than normal in patients with Alzheimer's disease. The study also showed association between the lower levels of these molecules with impaired memory function. Alzheimer's disease is ...

Our response to societal pressures about vaccination has a direct effect on the spread of pediatric infectious diseases in areas where inoculation is not mandatory, says new research published this week in Proceedings of the Royal Society B. By incorporating social norms into predictive mathematical modelling, a research team from the University of Guelph and the University of Waterloo found that they can foresee the observed patterns of population behaviour and disease spread during vaccine scares—times when anti-vaccine sentiment is strong. "If vaccination is not ...

Research by the University of Southampton has provided new insight into the consequence of accumulated 'misfolded proteins' in neurodegenerative disorders, such as Prion and Alzheimer's disease. Prion and Alzheimer's disease are protein misfolding brain diseases, where genetic mutations, or more commonly, interactions between an individual's genetics and environmental influences cause functional proteins in neurons to become misfolded or misrouted. In these diseases, there is a progressive death of nerve cells in specific brain regions, which is associated with the increasing ...

It's much easier to remember a place you have visited than a long, complicated password, which is why computer scientist Ziyad Al-Salloum of ZSS-Research in Ras Al Khaimah, UAE, is developing a system he calls geographical passwords. Writing in a freely available "open access" research paper in the International Journal of Security and Networks, Al-Salloum emphasizes how increasingly complicated our online lives are becoming with more and more accounts requiring more and more passwords. Moreover, he adds that even strong, but conventional passwords are a security risk ...

New Rochelle, NY, February 13, 2014—Food spoiling and poisoning caused by microbial contamination can cause major health, social, and economic problems. The broad scope of antimicrobial approaches to kill or prevent the growth of microorganisms in foods and beverages, including a variety of natural and artificial preservative strategies, are described in a comprehensive Review article in Industrial Biotechnology, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available on the Industrial Biotechnology website. In the Review "Ingredient ...

MAYWOOD, IL – New insights into the physiological causes of depression are leading to treatments beyond common antidepressants such as Prozac and Zoloft, researchers are reporting in the in the journal Current Psychiatry. Depression treatments on the horizon include new medications, electrical and magnetic stimulation of the brain and long-term cognitive behavioral therapy for stress management. Authors are Murali Rao, MD, and Julie M. Alderson, DO. Rao is professor and chair of the Department of Psychiatry and Behavioral Neurosciences at Loyola University Chicago ...

People living in cold, northern latitudes have bacteria in their guts that may predispose them to obesity, according to a new study by researchers at the University of California, Berkeley, and the University of Arizona, Tucson. The researchers' analysis of the gut microbes of more than a thousand people from around the world showed that those living in northern latitudes had more gut bacteria that have been linked to obesity than did people living farther south. The meta-analysis of six earlier studies by UC Berkeley graduate student Taichi Suzuki and evolutionary ...

If she loves you and then she loves you not, don't blame the petals of that daisy. Blame evolution. UCLA researchers analyzed dozens of published and unpublished studies on how women's preferences for mates change throughout the menstrual cycle. Their findings suggest that ovulating women have evolved to prefer mates who display sexy traits – such as a masculine body type and facial features, dominant behavior and certain scents – but not traits typically desired in long-term mates. So, desires for those masculine characteristics, which are thought to have been ...

Austin – February 14, 2014 - Money and parenting don't mix. That's according to new research that suggests that merely thinking about money diminishes the meaning people derive from parenting. The study is one among a growing number that identifies when, why, and how parenthood is associated with happiness or misery. "The relationship between parenthood and well-being is not one and the same for all parents," says Kostadin Kushlev of the University of British Columbia. While this may seems like an obvious claim, social scientists until now have yet to identify the psychological ...

(SACRAMENTO, Calif.) — When mothers feed their newborns formula in the hospital, they are less likely to fully breastfeed their babies in the second month of life and more likely to quit breastfeeding early, even if they had hoped to breastfeed longer, UC Davis researchers have found. "We are a step closer to showing that giving formula in the hospital can cause problems by reducing how much women breastfeed later," says Caroline Chantry, lead author and professor of clinical pediatrics at UC Davis Medical Center. "Despite being highly motivated to breastfeed their babies, ...

RICHLAND, Wash. -- In biology, a protein's shape is key to understanding how it causes disease or toxicity. Researchers who use X-rays to takes snapshots of proteins need a billion copies of the same protein stacked and packed into a neat crystal. Now, scientists using exceptionally bright and fast X-rays can take a picture that rivals conventional methods with a sheet of proteins just one protein molecule thick. Using a type of laser known as XFEL, the technique opens the door to learning the structural details of almost 25 percent of known proteins, many of which have ...

Suffering an injury to the head or neck increases ischemic stroke risk three-fold among trauma patients younger than 50, according to research presented at the American Stroke Association's International Stroke Conference 2014. "These findings are important because strokes after trauma might be preventable," said Christine Fox, M.D., M.A.S., lead author and assistant professor of neurology at the University of California San Francisco. Researchers studied the health records of 1.3 million patients younger than 50 years who had been treated in emergency trauma rooms. ...

Hispanic stroke patients admitted to hospitals in the border states of California, Arizona, New Mexico and Texas were less likely than non-Hispanics in the same border states to receive clot-busting drugs and more likely to die, according to research presented at the American Stroke Association's International Stroke Conference 2014. Researchers analyzed stroke care for Hispanic and non-Hispanic patients according to demographics and clinical characteristics in states bordering Mexico and states not on the Mexican border. They found: Of the nearly 35,000 Hispanic stroke ...

Stroke survivors often resume driving without being formally evaluated for ability — though stroke can cause deficits that can impair driving, according to research presented at the American Stroke Association's International Stroke Conference 2014. Researchers surveyed 162 stroke survivors a year after their strokes and found: More than 51 percent returned to driving — many a month after suffering a stroke. Only 5.6 percent received a formal driving evaluation. Eleven percent of those who returned to driving reported their strokes had greatly impacted their abilities ...
