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.

Researchers ID Key Transition to Problematic Drinking

October 21, 2014 8:10 am | by UC San Francisco | News | Comments

A team of researchers has found that a tiny segment of genetic material known as a microRNA plays a central role in the transition from moderate drinking to binge drinking and other alcohol use disorders.

Tarantula Toxin Exposes Activity in Live Cells

October 21, 2014 8:06 am | by UC Davis | Videos | Comments

Researchers have created a cellular probe that combines a tarantula toxin with a fluorescent compound to help scientists observe electrical activity in neurons and other cells. The probe binds to a voltage-activated potassium ion channel subtype, lighting up when the channel is turned off and dimming when it is activated.

Subliminal Aging Messages Improve Physical Functioning in Elderly

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.

Secrets of Dinosaur Ecology Found in Fragile Amber

October 20, 2014 2:41 pm | by The Geological Society of America | News | Comments

Ryan McKellar’s research sounds like it was plucked from Jurassic Park: he studies pieces of amber found buried with dinosaur skeletons. But rather than re-creating dinosaurs, McKellar uses the tiny pieces of fossilized tree resin to study the world in which the now-extinct behemoths lived.

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.

Starfish-like Shells Advance 3-D Printing of Pharmaceuticals

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.

New Hydrogen Mixture Sees Wild Molecular Interactions

October 20, 2014 2:27 pm | by Carnegie Institution | News | Comments

Scientists have combined hydrogen with its heavier sibling deuterium—which has an added neutron in its nucleus—and created a novel, disordered, "Phase IV"-material where the molecules interact differently than have been observed before.

Another Month, Another Global Heat Record Broken

October 20, 2014 2:20 pm | by Associated Press | News | Comments

It sounds like a broken record: Last month again set a new mark for global heat. And meteorologists say Earth is now on pace to tie the hottest year ever recorded, or more likely, to break it. The National Oceanic and Atmospheric Administration announced Monday that last month the globe averaged 60.3 F. That was the hottest September in 135 years of record keeping.
