Do gut bacteria rule our minds?

August 15, 2014 4:21 pm | by EurekAlert! | News | Comments

It sounds like science fiction, but it seems that bacteria within us — which outnumber our own cells about 100-fold — may very well be affecting both our cravings and moods to get us to eat what they want, and often are driving us toward obesity. In an article published this week in the journal BioEssays, researchers from UC San Francisco, Arizona State University and University of New Mexico concluded ...

New ways to treat solid tumors

August 15, 2014 3:24 pm | by Monash University | News | Comments

An international team of scientists has shown that an antibody against the protein EphA3, found in the micro-environment of solid cancers, has anti-tumor effects. As EphA3 is present in normal organs only during embryonic development but is expressed in blood cancers and in solid tumors, this antibody-based approach may be a suitable candidate treatment for solid tumors.

New nanotech invention improves effectiveness of the 'penicillin of cancer'

August 15, 2014 3:12 pm | by Jared Sagoff, Argonne National Laboratory | News | Comments

Scientists at the U.S. Department of Energy's Argonne National Laboratory have added a new weapon to oncologists' arsenal of anti-cancer therapies. By combining magnetic nanoparticles with one of the most common and effective chemotherapy drugs, Argonne researchers have created a way to deliver anti-cancer drugs directly into the nucleus of cancer cells.

Bats bolster brain hypothesis, maybe technology, too

August 15, 2014 2:49 pm | by EurekAlert! | News | Comments

Amid a neuroscience debate about how people and animals focus on distinct objects within cluttered scenes, some of the newest and best evidence comes from the way bats "see" with their ears, according to a new paper in the Journal of Experimental Biology. In fact, the perception process in question could improve sonar and radar technology.

Scientists racing to test Ebola vaccines in humans

August 15, 2014 10:59 am | by Matthew Perrone - Associated Press | News | Comments

Scientists are racing to begin the first human safety tests of two experimental Ebola vaccines, but it won't be easy to prove that the shots and other potential treatments in the pipeline really work. There are no proven drugs or vaccines for Ebola, a disease so rare that it's been hard to attract investments in countermeasures. But the current outbreak in West Africa—the largest in history—is fueling new efforts to ...

New gene editing method may help correct muscular dystrophy

August 15, 2014 10:52 am | by University of Texas Southwestern Medical Center | News | Comments

Univ. of Texas Southwestern Medical Center researchers successfully used a new gene editing method to correct a mutation that leads to Duchenne muscular dystrophy (DMD) in a mouse model of the condition. Researchers used a technique called CRISPR/Cas9-mediated genome editing, which can precisely remove a mutation in DNA, allowing the body's DNA repair mechanisms to ...

Laser physicists have found a way to make atomic-force microscope probes 20 times more sensitive and capable of detecting forces as small as the weight of an individual virus. The technique, developed by researchers at The Australian National University (ANU), hinges on ...

Memories of errors foster faster learning

August 15, 2014 10:18 am | by EurekAlert! | News | Comments

Using a deceptively simple set of experiments, researchers at Johns Hopkins have learned why people learn an identical or similar task faster the second, third and subsequent time around. The reason: They are aided not only by memories of how to perform the task, but also by memories of the errors made the first time.

Scientists fold RNA origami from a single strand

August 15, 2014 9:51 am | by EurekAlert! | News | Comments

RNA origami is a new method for organizing molecules on the nanoscale. Using just a single strand of RNA, many complicated shapes can be fabricated by this technique. Unlike existing methods for folding DNA molecules, RNA origamis are produced by enzymes and they simultaneously fold into pre-designed shapes. These features may allow designer RNA structures to ...

UT Arlington and Pediatrix partner to bring simulation training direct to practice
