Dignity in dementia: New research reveals the challenges of providing good nutrition in care homes Posted: 20 Jul 2015 06:21 PM PDT Unexplained weight loss is often seen in people with dementia, which can lead to further complications, including mental and physical deterioration. New research has revealed the challenges of providing good nutrition and hydration in people with dementia who live in care homes.

Iron-containing inflammatory cells seen in Alzheimer's brains Posted: 20 Jul 2015 02:58 PM PDT Examining post-mortem tissue from the brains of people with Alzheimer's disease, investigators identified what appear to be iron-containing microglia in a particular part of the hippocampus, a key brain structure whose integrity is critical to memory formation.

New Pap smear schedule led to fewer chlamydia tests, new study suggests Posted: 20 Jul 2015 02:56 PM PDT It's a tale of two tests: one for early signs of cervical cancer, the other for the sexually transmitted disease chlamydia. But a change in the recommended schedule for one may have dramatically lowered the chances that young women would get the other, a new study finds.

One-third of colorectal cancers diagnosed before 35 are hereditary, study finds Posted: 20 Jul 2015 02:56 PM PDT Hereditary colorectal cancers, caused by inherited gene mutations, are relatively rare for most patients. However, researchers have discovered a particularly high prevalence of hereditary cancers among those diagnosed with the disease before the age of 35.

Hereditary swellings caused by defective blood protein Posted: 20 Jul 2015 01:18 PM PDT Hereditary angioedema type III is a rare, hereditary, and serious disorder, characterized by painful swellings in the skin and other organs. An international team of scientists has published a study in which they show that the disease is caused by a defective blood protein, the so-called coagulation factor XII. The results from this study may contribute to future treatment strategies for patients with the disease.

Technique may reveal the age of moon rocks during spaceflight Posted: 20 Jul 2015 12:45 PM PDT Researchers are developing instruments and methods for measuring the ages of rocks encountered during space missions to the Moon or other planets. Many of the techniques used to date rocks on Earth are not practical in spaceflight, but a technique called laser ablation resonance ionization mass spectrometry can avoid the need for sophisticated sample preparation.

Fossil fuel emissions will complicate radiocarbon dating Posted: 20 Jul 2015 12:45 PM PDT Fossil fuel emissions could soon make it impossible for radiocarbon dating to distinguish new materials from artefacts that are hundreds of years old.

New insights into biofilm formation could lead to better therapies, but mysteries remain Posted: 20 Jul 2015 12:42 PM PDT Biofilms are tough, opportunistic, highly antibiotic resistant bacterial coatings that form on catheters and on medical devices implanted within the body. Investigators have now shown that a 'messenger molecule' produced by the opportunistic human pathogen, Pseudomonas aeruginosa, encourages bacteria to colonize catheters in the bladders of laboratory mice, where they form biofilms.

Infants use expectations to shape their brains Posted: 20 Jul 2015 12:42 PM PDT Infants can use their expectations about the world to rapidly shape their developing brains, researchers have found. A series of experiments with infants ages 5 to 7 months has shown that portions of babies' brains responsible for visual processing respond not just to the presence of visual stimuli, but also to the mere expectation of visual stimuli.

Novel monoclonal antibodies show promise for Alzheimer's disease treatment Posted: 20 Jul 2015 12:42 PM PDT Scientists have evidence that monoclonal antibodies they developed may provide the blueprint for effective treatments for Alzheimer's disease and other neurodegenerative diseases, such as Parkinson's disease.

Football helmet tests may not account for concussion-prone actions, study suggests Posted: 20 Jul 2015 12:42 PM PDT Concussions in football are caused by the sudden rotation of the skull, mounting evidence suggests. Researchers now have evidence that suggests current football helmet tests don't account for these movements.

How music training alters the teenage brain Posted: 20 Jul 2015 12:42 PM PDT Music training, begun as late as high school, may help improve the teenage brain's responses to sound and sharpen hearing and language skills, suggests a new study. The authors say that these results highlight music's place in the high school curriculum.

Inflammatory link discovered between arthritis, heart valve disease Posted: 20 Jul 2015 12:42 PM PDT Researchers have used models to identify a potential link between excess production of inflammatory proteins that cause rheumatoid arthritis and the development of heart valve disease. The research team discovered that a critical inflammatory protein involved in rheumatoid arthritis could also lead to inflammation and disease of the heart valves, including aneurysms. The research could lead to improved treatments for rheumatoid arthritis, and suggests investigating existing medicines that dampen inflammation to treat heart valve diseases, such as rheumatic heart disease.

New tool for investigating RNA gone awry Posted: 20 Jul 2015 12:42 PM PDT RNA is a fundamental ingredient in all known forms of life -- so when RNA goes awry, a lot can go wrong. A new technology offers the first real-time method to track and observe the dynamics of RNA distribution as it is transported inside living cells. 'Sticky-flares' have the potential to help scientists understand the complexities of RNA better than any analytical technique to date and observe and study the biological and medical significance of RNA misregulation.

Prawn solution to spread of deadly disease identified Posted: 20 Jul 2015 12:42 PM PDT A deadly disease may have met its match: a bug-eyed, pint-sized crustacean. The river prawn, a natural predator of parasite-carrying snails, proves effective at curbing the spread of schistosomiasis in West Africa, new research has found.

Lack of knowledge on animal disease leaves humans at risk Posted: 20 Jul 2015 12:42 PM PDT Researchers have painted the most detailed picture to date of major infectious diseases shared between wildlife and livestock, and found a huge gap in knowledge about diseases which could spread to humans.

New method to deliver glucose to cancer cells could prove key to defeating deadly cancers Posted: 20 Jul 2015 11:53 AM PDT Scientists have, for the first time, demonstrated the importance of sodium-dependent glucose transporters (SGLTs) in delivering glucose to pancreatic and prostate cancer cells. Their study results show promising evidence that current SGLT inhibitor drugs (such as those commonly used to treat diabetes) could potentially be used to block glucose uptake and reduce tumor growth in these cancers. The researchers also utilized PET imaging to measure SGLT activity, suggesting the technology could be used to better diagnose pancreatic and prostate cancers. Pancreatic and prostate cancers are among the most deadly forms of cancer in men, and new therapies are urgently needed to combat these diseases.

Michelangelo likely used mathematics when painting the Creation of Adam Posted: 20 Jul 2015 11:52 AM PDT New research provides mathematical evidence that Michelangelo used the Golden Ratio of 1.6 when painting The Creation of Adam on the ceiling of the Sistine Chapel. The Golden Ratio is found when you divide a line into two parts so that the longer part divided by the smaller part is equal to the whole length divided by the longer part.

High cost of hydrogen pipelines calculated: Research shows how to reduce it Posted: 20 Jul 2015 11:52 AM PDT Scientists have put firm numbers on the high costs of installing pipelines to transport hydrogen fuel and also found a way to reduce those costs. Researchers calculated that hydrogen-specific steel pipelines can cost as much as 68 percent more than natural gas pipelines. However, they say, hydrogen transport costs could be reduced safely for most pipeline sizes and pressures by modifying industry codes to allow the use of a higher-strength grade of steel alloy without requiring thicker pipe walls.

Achieving equity in higher education Posted: 20 Jul 2015 11:13 AM PDT In a retrospective account of their scholarly work over the past 45 years, researchers show how the struggle to achieve greater equity in American higher education is intimately connected to issues of character development, leadership, civic responsibility, and spirituality. The authors advocate that colleges and universities focus greater attention on developing student values and other personal qualities that will produce a new generation of citizens who are committed to creating a more just and equitable society.

Study uncovers key differences among ALS patients Posted: 20 Jul 2015 11:13 AM PDT Key differences between patients with sporadic amyotrophic lateral sclerosis (ALS or Lou Gehrig's disease) and those with the most common genetic form of ALS, a mutation in the C9orf72 gene have been identified by a group of researchers.

Celebrity influence on breast cancer screening Posted: 20 Jul 2015 11:13 AM PDT Angelina Jolie received widespread media attention in 2013 when she told the public that she'd tested positive for BRCA1, a gene associated with an increased risk of breast and ovarian cancers, and subsequently had a double mastectomy. Now research shows that this publicity did influence some women's intentions to seek out similar genetic testing.

Abundance of certain elements in Earth dictate whether plate tectonics can happen Posted: 20 Jul 2015 11:13 AM PDT Planet Earth is situated in what astronomers call the Goldilocks Zone -- a sweet spot in a solar system where a planet's surface temperature is neither too hot nor too cold. An ideal distance from a home star -- in Earth's case, the sun -- this habitable zone, as it is also known, creates optimal conditions that prevent water from freezing and generating a global icehouse or evaporating into space and creating a runaway greenhouse.

The New York Times can predict your future weight Posted: 20 Jul 2015 11:13 AM PDT What you're reading now secretly tells you whether your country will be skinnier or fatter in three years. After analyzing 50 years of all the food words mentioned in major newspapers like the New York Times and London Times, a new study shows that the food words trending today in 2015 will predict a country's obesity level in three years -- in 2018.

Changing climate lengthens forest fire season Posted: 20 Jul 2015 10:36 AM PDT Over a 35-year period, the length of forest fire seasons worldwide increased by 18.7 percent due to more rain-free days and hotter temperatures, according to research. The study examined weather data from 1979 through 2013 to determine how a changing climate impacts forest ecosystems.

Is Facebook use always associated with poorer body image and risky dieting? Posted: 20 Jul 2015 10:33 AM PDT College women who are more emotionally invested in Facebook and have lots of Facebook friends are less concerned with body size and shape and less likely to engage in risky dieting behaviors. But that's only if they aren't using Facebook to compare their bodies to their friends' bodies, according to the authors of a surprising new study.
