Tissue regeneration using anti-inflammatory nanomolecules Posted: 22 Aug 2014 09:46 AM PDT Anyone who has suffered an injury can probably remember the after-effects, including pain, swelling or redness. These are signs that the body is fighting back against the injury. When tissue in the body is damaged, biological programs are activated to aid in tissue regeneration. Now, researchers are working on innovative approaches to tissue regeneration in order to improve the lives of patients with urinary bladder dysfunction.

In our digital world, are young people losing the ability to read emotions? Posted: 22 Aug 2014 06:42 AM PDT Are young people losing the ability to read emotions in our digital world? Scientists report that sixth-graders who went five days without even glancing at a smartphone, television or other screen did substantially better at reading emotions than sixth-graders from the same school who, as usual, spent hours each day looking at their smartphones and other screens.

Proteins: New class of materials discovered Posted: 22 Aug 2014 06:41 AM PDT Scientists have characterized a new class of materials called protein crystalline frameworks. Thanks to certain helper substances, in PCFs proteins are fixated in a way so as to align themselves symmetrically, forming highly stable crystals.

Voyager map details Neptune's strange moon Triton Posted: 22 Aug 2014 06:35 AM PDT NASA's Voyager 2 spacecraft gave humanity its first close-up look at Neptune and its moon Triton in the summer of 1989. Like an old film, Voyager's historic footage of Triton has been "restored" and used to construct the best-ever global color map of that strange moon. The map, produced by Paul Schenk, a scientist at the Lunar and Planetary Institute in Houston, has also been used to make a movie recreating that historic Voyager encounter, which took place 25 years ago, on August 25, 1989.

Playing hunger games: Are gamified health apps putting odds in your favor? Posted: 22 Aug 2014 05:42 AM PDT For many people, finding motivation to exercise is a challenge. Thankfully, there are Zombies chasing you. At least that's the approach of Zombies, Run! -- one of more than 31,000 health and fitness apps on the market today, and one of the growing number of apps that use games to increase physical activity. Gamification is currently the popular trend for mobile fitness apps, but whether or not it's the best way to exercise remains to be seen.

Water splitter runs on an ordinary AAA battery Posted: 22 Aug 2014 05:40 AM PDT Although touted as zero-emissions vehicles, most fuel cell vehicle run on hydrogen made from natural gas. Now scientists have developed a low-cost, emissions-free device that uses an ordinary AAA battery to produce hydrogen by water electrolysis. Unlike other water splitters that use precious-metal catalysts, the electrodes in this device are made of inexpensive and abundant nickel and iron.

Spectacular supernova's mysteries revealed Posted: 22 Aug 2014 05:39 AM PDT Astronomers are delving into the mystery of what caused a spectacular supernova in a galaxy 11 million light years away, seen earlier this year. The supernova, a giant explosion of a star and the closest one to the Earth in decades, was discovered earlier this year by chance. These phenomena are extremely important to study because they provide key information about our universe, including how it is expanding and how galaxies evolve.

Breakthrough in imaging gold nanoparticles to atomic resolution by electron microscopy Posted: 22 Aug 2014 05:39 AM PDT Nanometer-scale gold particles are intensively investigated for application as catalysts, sensors, drug delivery devices, biological contrast agents and components in photonics and molecular electronics. Gaining knowledge of their atomic-scale structures, fundamental for understanding physical and chemical properties, has been challenging. Now, researchers at have demonstrated that high-resolution electron microscopy can be used to reveal a three-dimensional structure in which all gold atoms are observed.

Extracorporeal support can significantly increase number of organs for transplant Posted: 22 Aug 2014 05:37 AM PDT Using heart-lung support technology, one Transplant Center was able to increase the number of kidneys, livers and pancreases available for transplant by about 20 percent. As of Aug. 6, 2014, 123,191 people nationwide were waiting for a solid organ transplant in the United States. The Institute of Medicine has named donation after circulatory determination of death as the number one research priority to improve organ donation.

Electronic alerts significantly reduce catheter-associated urinary tract infections Posted: 22 Aug 2014 05:36 AM PDT Targeted automated alerts in electronic health records significantly reduce urinary tract infections in hospital patients with urinary catheters. In addition, when the design of the alert was simplified, the rate of improvement dramatically increased.

Shaping the future of nanocrystals: First direct observation of facet formation in nanocubes Posted: 21 Aug 2014 01:13 PM PDT Researchers have recorded the first direct observations of how facets form and develop on platinum nanocubes in solution, pointing the way towards more sophisticated and effective nanocrystal design and revealing that a nearly 150 year-old scientific law describing crystal growth breaks down at the nanoscale.

Wildland fire modeling can lead to better predictions Posted: 19 Aug 2014 12:52 PM PDT If we can better understand scientifically how wildland fires behave, we'll have a better chance to accurately predict their evolution, researchers say. When wildland fuel distribution and ignition potential can be assessed, and the regions within a fire where intense energy in the form of heat is released can be determined, the rate and area of a fire's spread can be predicted days in advance. That will open doors to scientific advances from firefighting technologies to logistics, and can even influence the design of subdivisions, developments and homes.
