An Eye on Imaging Science

July 31, 2015 | by Lindsay Hock, Editor | Articles | Comments

Image science and technology attracts researchers from academic and government institutions, as well as practitioners in the imaging industry globally. The diverse research interest and the multidisciplinary characteristics of the imaging field encourage competing ideas to be presented and tested by researchers. This, in turn, prompts imaging technologies to quickly respond to challenges from various scientific disciplines.

Bees Vaccinate Offspring Naturally

August 3, 2015 6:30 pm | by Greg Watry, Digital Reporter | Articles | Comments

Dalial Freitak, a postdoctoral researcher with the Univ. of Helsinki, knew the egg-yolk protein vitellogenin was used as food for developing embryos of egg-laying animals. While the protein appeared to have some function regarding immunity, the exact role was unknown to her. Then Freitak heard a presentation from colleague Heli Salmela, who was studying the protein for her PhD thesis, and found the protein can bind to bacterial pieces.


Explanation proposed for puzzling electron heat loss in fusion plasmas

August 3, 2015 4:12 pm | by Raphael Rosen, Princeton Plasma Physics Laboratory | News | Comments

Creating controlled fusion energy entails many challenges, but one of the most basic is heating plasma to extremely high temperatures and then maintaining those temperatures. Now a team has proposed an explanation for why the hot plasma within fusion facilities called tokamaks sometimes fails to reach the required temperature, even as researchers pump beams of fast-moving neutral atoms into the plasma in an effort to make it hotter.


Searching for a Functional Cure for HIV

August 3, 2015 3:40 pm | by Lindsay Hock, Editor | Articles | Comments

In 2014, more than 1.2 million people in the U.S. were noted by the Centers for Disease Control and Prevention (CDC) as living with HIV infection. Almost one in eight, or 12.8%, are unaware of their infection. The CDC estimates that 1,218,400 person aged 13 and older are living with HIV infection, including 156,300 who are unaware of their infection. Over the past decade, the number of people living with HIV has increased.


If Sir David Attenborough Was a Lizard…

August 3, 2015 3:15 pm | by Greg Watry, Digital Reporter | Articles | Comments

Rainbow-like in color, the lizards meander out into the sunshine from a rock crevice in droves. “In the early morning, the Augrabies flat lizards emerge from the cracks in the rocks, where they spent the night, and bask in the sun to warm up,” says Sir David Attenborough, who lies on his stomach next to the rock in a scene from the 2008 BBC documentary series “Life in Cold Blood."


Artificial blood vessels become resistant to thrombosis

August 3, 2015 2:15 pm | by Dmitry Malkov, ITMO Univ. | News | Comments

Scientists from ITMO Univ. developed artificial blood vessels that are not susceptible to blood clot formation. The achievement was made possible by a new generation of drug-containing coating applied to the inner surface of the vessel. Surgery, associated with cardiovascular diseases, such as ischemia, often require the implantation of vascular grafts.


Unique Bedrock May Preserve Martian Ancient Life

August 3, 2015 1:45 pm | by Greg Watry, Digital Reporter | Articles | Comments

NASA’s Curiosity Mars rover may have found bedrock with “ideal conditions” for preserving ancient organic material, according to the space agency. The target, named “Elk,” features high levels of silica, a rock-forming compound comprised of silicon and oxygen. On Earth, the compound is known as quartz.


Vaccine with virus-like nanoparticles is an effective treatment for RSV

August 3, 2015 1:15 pm | by LaTina Emerson, Georgia State Univ. | News | Comments

A vaccine containing virus-like nanoparticles, or microscopic, genetically engineered particles, is an effective treatment for respiratory syncytial virus (RSV), according to researchers at Georgia State Univ. Their findings, published in the International Journal of Nanomedicine, suggest this vaccine induces long-term protection against RSV and could be a novel treatment option for this disease. There is no licensed RSV vaccine.


Why Design Engineers Find Chemical Etching So Hard to “Resist”

August 3, 2015 12:30 pm | by Fotolab | Articles | Comments

For design engineers looking to manufacture metal parts with complex geometries, maintain the flexibility to make last minute design changes and mass produce prototypes quickly, chemical etching is the answer. When it comes to metal part fabrication, chemical etching offers an economical and efficient solution. This manufacturing process allows for the mass production of intricate, thin metal parts.


Better together: Graphene-nanotube hybrid switches

August 3, 2015 12:00 pm | by Allison Mills, Michigan Technological Univ. | News | Comments

Graphene has been called a wonder material, capable of performing great and unusual material acrobatics. Boron nitride nanotubes are no slackers in the materials realm either, and can be engineered for physical and biological applications. However, on their own, these materials are terrible for use in the electronics world.


The R&D Index: Market Pulse – August 3, 2015

August 3, 2015 11:00 am | by Tim Studt, Contributing Editor | Articles | Comments

The R&D Index: Market Watch for the week ending July 31, 2015, closed at 1,653.60 for the 25 companies in the R&D Index. The Index was adjusted down approximately 32.89 points when Astra Zeneca split 2:1 on July 27, 2015. With this adjustment the market was up approximately 1.57% (or nearly 26 points) over the previous week (ending July 24, 2015).


Scientists curve nanoparticle sheets into complex forms

August 3, 2015 8:05 am | by Carla Reiter, Argonne National Laboratory | News | Comments

Scientists have been making nanoparticles for more than two decades in 2-D sheets, 3-D crystals and random clusters. But they have never been able to get a sheet of nanoparticles to curve or fold into a complex 3-D structure. Now researchers from the Univ. of Chicago, the Univ. of Missouri and Argonne National Laboratory have found a simple way to do exactly that.


New design brings world’s first solar battery to performance milestone

August 3, 2015 7:46 am | by Pam Frost Gorder, Ohio State Univ. | News | Comments

After debuting the world's first solar air battery last fall, researchers at The Ohio State Univ. have now reached a new milestone. In the Journal of the American Chemical Society, they report that their patent-pending design, which combines a solar cell and a battery into a single device, now achieves a 20% energy savings over traditional lithium-iodine batteries.


Why tumors need respiration

August 3, 2015 7:38 am | by Jessa Gamble, MIT News Correspondent | News | Comments

Mitochondria are well known for their role as powerhouses in our cells, using respiration to release the energy in the food we eat and trapping that energy in the molecule adenosine triphosphate, or ATP. In two companion papers published in Cell, Massachusetts Institute of Technology researchers reveal why proliferating cells require mitochondrial respiration.


U.S. Researchers Call for a Ban on Salamander Imports

August 2, 2015 1:00 pm | by Greg Watry, Digital Reporter | Articles | Comments

Researchers from various California universities are calling for the U.S. Fish and Wildlife Service to enact an immediate ban on live salamander imports to the U.S. in light of a fatal fungus that caused a 96% fatality rate among infected European salamander species.
