Gait Linked to Dementia

October 23, 2014 7:00 am | by Newcastle Univ. | News | Comments

Researchers have found a definitive link between gait– the way someone walks– and early changes in cognitive function in people with Parkinson's disease. And the find could mean that gait may be used as an early warning sign to help predict the development of cognitive impairment and dementia in Parkinson’s.

Method Allows Fast Analysis of Cancer Mutations

October 23, 2014 7:00 am | by MIT, Anne Trafton | News | Comments

Sequencing the genomes of tumor cells has revealed thousands of genetic mutations linked with cancer. However, sifting through this deluge of information to figure out which of these mutations actually drive cancer growth has proven to be a tedious, time-consuming process. Now, researchers have developed a new way to model the effects of these genetic mutations in mice.

Dental Care Linked to Respiratory Risks in ICU

October 22, 2014 2:00 pm | by Society for Healthcare Epidemiology of America | News | Comments

1918's Spanish Flu Can Teach Us About Pandemics

October 22, 2014 2:00 pm | by Michigan State Univ. | News | Comments

Just in time for flu season, a new study of “the mother of all pandemics” could offer insight into infection control measures for the flu and other epidemic diseases. In 1918, the Spanish flu killed 50 million people worldwide, 10 to 20 million of whom were in India. In the U.S. alone, the Spanish flu claimed 675,000 lives in nine months.

Peanuts in Dust Linked to Allergy in Kids with Mutation

October 22, 2014 7:00 am | by King’s College London | News | Comments

A new study has found a strong link between exposure to peanut protein in household dust during infancy and the development of peanut allergy in children genetically predisposed to a skin barrier defect.

Shift Workers Should Skip High-iron Foods at Night

October 22, 2014 7:00 am | by Univ. of Utah | News | Comments

Workers punching in for the graveyard shift may be better off not eating high-iron foods at night so they don’t disrupt the circadian clock in their livers. Disrupted circadian clocks, researchers believe, are the reason that shift workers experience higher incidences of type 2 diabetes, obesity and cancer.

Experimental Drug May Treat Norovirus

October 21, 2014 2:00 pm | by Univ. of Cambridge | News | Comments

An experimental drug currently being trialed for influenza and Ebola viruses could have a new target: norovirus, often known as the winter vomiting virus. A team of researchers has shown that the drug, favipiravir, is effective at reducing– and in some cases eliminating– norovirus infection in mice.

Herb Molecule Holds Potential for Drug Development

October 21, 2014 9:01 am | by Nanyang Technological Univ. | News | Comments

Scientists have discovered a new molecule that can join together chains of amino acids. Only three other known molecules have been discovered to perform this function, which is an important process in the development of new drugs. A key difference is that the new molecule can do the same process 10,000 times faster than the other three and “cleanly,” without leaving any residue behind.

Proteins Linked to Drug Side Effects

October 21, 2014 8:29 am | by Lawrence Livermore National Laboratory | News | Comments

Researchers have discovered a high-tech method of using supercomputers to identify proteins that cause medications to have certain adverse drug reactions, or side effects. They are using high-performance computers to process proteins and drug compounds in an algorithm that produces reliable data outside of a laboratory setting for drug discovery.

Research Points to Off Switch for Drug Resistance in Cancer

October 21, 2014 8:23 am | by Salk Institute for Biological Studies | News | Comments

Scientists have uncovered details about how cancer is able to become drug resistant over time, a phenomenon that occurs because cancer cells within the same tumor aren't identical— the cells have slight genetic variation, or diversity. Variations in breast cancer cells' RNA, the molecule that decodes genes and produces proteins, helps the cancer evolve more quickly than previously thought.

CD8 T Cells Will Fight Many Viruses

October 21, 2014 8:14 am | by Brown Univ. | News | Comments

Scientists think of CD8 T cells as long-lived cells that become tuned to fight just one pathogen, but a new study finds that once CD8 T cells fight one pathogen, they also join the body's "innate" immune system, ready to answer the calls of the cytokine signals that are set off by a wide variety of infections.

October 20, 2014 2:53 pm | by Yale | News | Comments

Older individuals who are subliminally exposed to positive stereotypes about aging showed improved physical functioning that can last for several weeks. Researchers used a novel intervention method to examine for the first time whether exposure to positive age stereotypes could weaken negative age stereotypes and their effects over time, and lead to healthier outcomes.

Study Charts Fate of Chemicals Affecting Human Health, Environment

October 20, 2014 2:49 pm | by Arizona State Univ.'s Biodesign Institute | News | Comments

In a new study a researcher at Arizona State Univ.'s Biodesign Institute examines the trajectory of chemicals appearing as emergent threats to human or environmental health. The study reveals that around 14 years typically elapse from the onset of initial safety concerns about a given chemical to the height of concern and appropriate action. This extended timeline implies protracted exposure to CECs for a large number of people.

Brain Activity Provides Evidence for Internal Calorie Counter

October 20, 2014 2:38 pm | by Association for Psychological Science | News | Comments

As you glance over a menu or peruse the shelves in a supermarket, you may be thinking about how each food will taste and whether it’s nutritious, or you may be trying to decide what you’re in the mood for. A new neuroimaging study suggests that while you’re thinking all these things, an internal calorie counter of sorts is also evaluating each food based on its caloric density.

October 20, 2014 2:34 pm | by Univ. of Michigan | News | Comments

In a design that mimics a hard-to-duplicate texture of starfish shells, Univ. of Michigan engineers have made rounded crystals that have no facets. The process used to manufacture them—organic vapor jet printing—might lend itself to 3D-printing medications that absorb better into the body and make personalized dosing possible.
