Cages offer new direction in sustainable catalyst design

July 24, 2015 1:15 pm | by Scott Gordon, Univ. of Wisconsin-Madison | News | Comments

Univ. of Wisconsin-Madison engineers have developed a new approach to structuring the catalysts used in essential reactions in the chemical and energy fields. The advance offers a pathway for industries to wean themselves off of platinum, one of the scarcest metals in the Earth's crust.


Tiny mechanical wrist gives dexterity to needlescopic surgery

July 24, 2015 12:20 pm | by David Salisbury, Vanderbilt Univ. | Videos | Comments

With the flick of a tiny mechanical wrist, a team of engineers and doctors at Vanderbilt Univ.’s Medical Engineering and Discovery Laboratory hope to give needlescopic surgery a whole new degree of dexterity. Needlescopic surgery, which uses surgical instruments shrunk to the diameter of a sewing needle, is the ultimate form of minimally invasive surgery.


EU regulator recommends first license for malaria vaccine

July 24, 2015 12:04 pm | by Maria Cheng, AP Medical Writer, Associated Press | News | Comments

The European Medicines Agency has recommended approving what would be the world's first licensed malaria vaccine, even though it's only about 30% effective and its protection fades over time. In a statement Friday, the agency endorsed the vaccine's use outside Europe, a regulatory process that helps speed new medicines to the market.


Magnetic material unnecessary to create spin current

July 24, 2015 11:45 am | by Carla Reiter, Argonne National Laboratory | News | Comments

It doesn’t happen often that a young scientist makes a significant and unexpected discovery, but postdoctoral researcher Stephen Wu of Argonne National Laboratory just did exactly that. What he found, that you don't need a magnetic material to create spin current from insulators, has important implications for the field of spintronics.


Worming into our hearts

July 24, 2015 11:00 am | by Rob Matheson, MIT News Office | Videos | Comments

Tasting and spitting out toxic food is a survival trait shared by many complex organisms. Now Massachusetts Institute of Technology researchers have shown that a simple roundworm, Caenorhabditis elegans, has the ability to spit out potentially deadly substances—a finding that could have surprising implications for human heart research.


Long-Time Searcher: Loch Ness Monster May be Catfish

July 24, 2015 10:45 am | by Greg Watry, Digital Reporter | Articles | Comments

Steve Feltham, on his Website, recalls he became fascinated with the Loch Ness Monster when he was seven-years-old, back in 1970. During that time, he was introduced to a team of volunteers who set up camp near Urquhart Castle in hopes of finding the fabled beast. From that point forward, he intermittently returned to Loch Ness in search of Nessie.


So What’s the Deal with Solar Airline Food?

July 24, 2015 8:43 am | by Greg Watry, Digital Reporter | Articles | Comments

Airline food may not be best part of a traveler’s experience, but most layman only deal with the food for a limited amount of hours. And, even so, it’s always possible to pack your own food for a flight. But what if you’re flight lasted close to 118 hrs over the Pacific Ocean, from Japan to Hawaii? Unlike highways, there are no rest stops. Whatever you’re eating, you’re packing.


Innovative algorithm helps decipher how drugs work inside the body

July 24, 2015 7:16 am | by Lucky Tran, Columbia Univ. Medical Center | News | Comments

Researchers at Columbia Univ. Medical Center have developed a computer algorithm that is helping scientists see how drugs produce pharmacological effects inside the body. The study, published in Cell, could help researchers create drugs that are more efficient and less prone to side effects, suggest ways to regulate a drug's activity and identify novel therapeutic uses for new and existing compounds.


Tasty Prawns Prevent Blood Flukes

July 24, 2015 7:00 am | by Greg Watry, Digital Reporter | Articles | Comments

Although uncommon in the U.S., schistosomiasis is a parasitic disease that has been reported in 78 countries. In 2013, at least 261 million people required preventative treatment for the disease, with at least 90% of those treated inhabiting Africa. Transmission is fairly simple.


How to Determine If a Mesh is Fine Enough for Accurate Results

July 23, 2015 6:00 pm | by Michael Bak, PhD, Senior Engineering Manager, CAE Associates | Articles | Comments

Analysts working on finite element models can spend a great deal of time obsessing over their meshes. If they use too many elements, a model may take a long time to run. But if they don’t use enough elements, solution accuracy may suffer. Balance is essential. Your mesh must be complete enough to provide an accurate solution, without being so large that it takes too long to run.


Programming adult stem cells to treat muscular dystrophy

July 23, 2015 5:25 pm | by American Chemical Society | News | Comments

Stem cells hold great potential for addressing a variety of conditions from spinal cord injuries to cancer, but they can be difficult to control. Scientists are now reporting in ACS Nano a new way to mimic the body’s natural approach to programming these cells. Using this method, they successfully directed adult stem cells to turn specifically into muscle, which could potentially help treat patients with muscular dystrophy.


Mighty Mussel Glue for Surgery

July 23, 2015 4:30 pm | by Greg Watry, Digital Reporter | Articles | Comments

Inspired by biological functions seen in mussels and insects, Korean scientists have manufactured a nontoxic surgical glue, which seals surgical openings within one minute, and may become a viable replacement for sutures and staples.


Finding could lead to cheap, efficient metal-based solar cells

July 23, 2015 3:15 pm | by Jade Boyd, Rice Univ. | News | Comments

New research from Rice Univ. could make it easier for engineers to harness the power of light-capturing nanomaterials to boost the efficiency and reduce the costs of photovoltaic solar cells. Although the domestic solar-energy industry grew by 34% in 2014, fundamental technical breakthroughs are needed if the U.S. is to meet its national goal of reducing the cost of solar electricity to 6 cents per kilowatt-hour.


Make mine a decaf: Breakthrough in knowledge of how nanoparticles grow

July 23, 2015 2:30 pm | by Univ. of Leicester | News | Comments

A team of researchers from the Univ. of Leicester and France's G2ELab-CNRS in Grenoble have, for the first time, observed the growth of free nanoparticles in helium gas in a process similar to the decaffeination of coffee, providing new insights into the structure of nanoparticles. Nanoparticles have a very large surface area compared with their volume and are often able to react very quickly.


Boosting wireless power transfer with magnetic field enhancement

July 23, 2015 1:15 pm | by Matt Shipman, News Services, North Carolina State Univ. | News | Comments

Research from North Carolina State Univ. and Carnegie Mellon Univ. shows that passing wireless power transfer through a magnetic resonance field enhancer (MRFE)—which can be as simple as a copper loop—can boost the transfer efficiency by at least 100% as compared to transferring through air alone. MRFE use could potentially boost transfer efficiency by as much as 5,000% in some systems, experts say.
