In this work, Dr. Diana and fellow researchers propose a low cost technique able to produce microfluidic devices for biomedical applications. The most common technique to fabricate biomedical microdevices is soft-lithography. However, it is a costly and time-consuming technique. Progress in manufacturing milling tools smaller than 100 µm, has enabled the use of micromilling machines to fabricate microfluidic devices capable of performing cell separation.

A research team led by archaeologists at the University of York used traditional techniques to create replicas of ritual headdresses made by hunter-gatherers 11,000 years ago in North Western Europe.
Flint blades, hammerstones and burning were among the tools and techniques they employed to fashion reproductions of shamanic headdresses discovered during excavations at the Early Mesolithic site at Star Carr in North Yorkshire.
Airport scanners can detect the explosive compounds that have been used in recent terrorist bombings, but these attacks didn't happen inside the protected spaces of terminals. They occurred in crowded public places where detection is a huge challenge. An article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, explores whether new portable detectors could be a solution.
Tropical Cyclone Fantala continued to strengthen in the Southern Indian Ocean and NASA/JAXA's Global Precipitation Measurement (GPM) satellite found very heavy rain in the system.
Scientists have obtained high resolution satellite images that paint a stark picture of how tropical glaciers in the Pacific have retreated over the past decade.
The images taken from the Pleaides satellites reveal that the formerly extensive Carstenz Glacier of West Papua New Guinea has almost completely disappeared, while the once continuous East North Wall Firn has split into a number of much smaller fragments.
One of the major questions today is: What are the ice sheets going to do in an ever-warming climate? Ice sheets of Greenland and Antarctica are major contributors to the sea level rise, which can make life difficult for many coastal nations in the near future.
Galaxies, it seems, are sociable animals and they like to gather together in large groups, known as clusters. Actually it's gravity that holds the galaxies in the cluster close together as a single entity, with the pull of gravity arising from large amounts of dark matter, as well as from the galaxies we can see. Clusters can contain anything between about 100 and 1000 galaxies and can be between about 5 and 30 million light-years across.
DURHAM, N.C. -- As energy companies decide what to do with aging coal ash disposal facilities in North Carolina and across the nation, they may be overlooking a fundamental but potentially critical variable -- oxygen.
In a new study appearing in the April issue of Applied Geochemistry, researchers from Duke University demonstrate that the level of oxygen in a coal ash disposal site can greatly affect how much toxic selenium and arsenic can be leached from the system.
A mobile-phone-based system for rabies surveillance in Tanzania is demonstrating huge potential for mobile technologies to improve public health service delivery, especially in resource-poor settings, according to a new article in PLOS Medicine by Katie Hampson from the University of Glasgow, UK, and colleagues.
Heart failure affects over one million people in France. Although the blood system is the first to have been explored for the purpose of improving heart function, a study by Inserm has revealed the potential of a secondary system that had previously received scant attention. The researchers analysed the heart lymphatic system in an animal model. They showed that this system was highly impaired following a myocardial infarction. Using a biotherapy based on the injection of innovative microparticles, they succeeded in regenerating lymphatic vessels in a targeted manner.
Powerful thunderstorms circled the low-level center of newborn Tropical Cyclone Fantana in infrared imagery from NASA's Aqua satellite.
At 1800 GMT (2 p.m. EDT) on April 11, Tropical Cyclone Fantala formed from System 99S near 13.0 degrees south and 71.2 degrees east in the Southern Indian Ocean. It was 354 nautical miles southeast of Diego Garcia.
Older adults, who are Facebook's fastest growing demographic, are joining the social network to stay connected and make new connections, just like college kids who joined the site decades ago, according to Penn State researchers.
"Earlier studies suggest a positive relationship between bonding and bridging social capital and Facebook use among college students," said Eun Hwa Jung, a doctoral candidate in mass communications. "Our study extends this finding to senior citizens."
GAITHERSBURG, MD - April 12, 2016 - The Institute for In Vitro Sciences (IIVS) brought together stakeholders from industry, government and academia to discuss considerations for exposure and dosimetry for non-animal testing during its 2.5-day workshop, "In Vitro Exposure Systems and Dosimetry Assessment Tools for Inhaled Tobacco Products", held April 4-6, 2016 in Bethesda, MD. Uniquely focused on in vitro testing, the workshop is the only known event of its kind.
A group of scientists from ITMO University in Saint Petersburg, Russia has developed a novel approach to the construction of quantum communication systems for secure data exchange. The experimental device based on the results of the research is capable of transmitting single-photon quantum signals across distances of 250 kilometers or more, which is on par with other cutting edge analogues. The research paper was published in the Optics Express journal.
Pasadena, CA-- You can never predict what treasure might be hiding in your own basement. We didn't know it a year ago, but it turns out that a 1917 image on an astronomical glass plate from our Carnegie Observatories' collection shows the first-ever evidence of a planetary system beyond our own Sun. This unexpected find was recognized in the process of researching an article about planetary systems surrounding white dwarf stars in New Astronomy Reviews.
