Surgeons may get remote assistance with new “telementoring” system

August 26, 2015 9:00 am | by Emil Venere, Purdue Univ. | Videos | Comments

Researchers at Purdue Univ. and the Indiana Univ. School of Medicine are developing an "augmented reality telementoring" system to provide effective support to surgeons on the battlefield from specialists located thousands of miles away. In telementoring, a surgeon performing an operation receives guidance remotely from an expert using telecommunications.

Making the air fair

August 26, 2015 8:00 am | by Peter Dizikes, MIT News Office | News | Comments

Nobody likes flight delays, but they are a common occurrence: In 2011, about 20% of U.S. flights were at least 15 min behind schedule. Those delays irritate passengers and, in 2010, added an estimated $6.5 billion to U.S. airlines’ operating costs.

3-D-printed microscopic fish do more than swim

August 26, 2015 7:41 am | by Liezel Labios, Univ. of California, San Diego | News | Comments

Nanoengineers at the Univ. of California, San Diego used an innovative 3-D printing technology they developed to manufacture multipurpose fish-shaped microrobots that swim around efficiently in liquids, are chemically powered by hydrogen peroxide and magnetically controlled. These proof-of-concept synthetic microfish will inspire a new generation of "smart" microrobots.

E. coli Growth Inhibited by Flu Medications

August 26, 2015 7:21 am | by Greg Watry, Digital Reporter | Articles | Comments

Through a technique known as pyrosequencing, Stanford Univ. researchers in 2008 found the bacteria community in the colon is made of at least 5,600 species, or strains. It was a huge moment for gut microbiota, as previous estimates put the number upwards of 500.

Brightfield LED Microscope Illuminator

August 26, 2015 5:30 am | by Prior Scientific | Product Releases | Comments

Prior Scientific has announced two additions to their wide range of illumination products for microscopy: the new LDB100F and LDB101F Brightfield LEDs. Using a Brightfield LED with a 550-nm flip-in filter in the light path reduces background fluorescence attributed to stray light. The Brightfield LED replaces the standard light source and provides all the advantages of LED illumination in a flexible package that can be fitted to most modern upright...

Researchers combine disciplines, computational programs to determine atomic structure

August 25, 2015 5:30 pm | by Univ. of Illinois | News | Comments

A team from the Univ. of Illinois at Urbana-Champaign and Indiana Univ. combined two techniques to determine the structure of cyanostar, a new abiological molecule that captures unwanted negative ions in solutions.

Quantum diffraction at a breath of nothing

August 25, 2015 4:25 pm | by Univ. of Vienna | News | Comments

The quantum mechanical wave nature of matter is the basis for a number of modern technologies like high resolution electron microscopy, neutron-based studies on solid state materials or highly sensitive inertial sensors working with atoms. The research in the group around Prof. Markus Arndt at the Univ. of Vienna is focused on how one can extend such technologies to large molecules and cluster.

Using Drones to Track Wildlife

August 25, 2015 1:15 pm | by Greg Watry, Digital Reporter | Articles | Comments

From recreational uses to military operations, drones are becoming ubiquitous in society. Already, the technology is being applied to help monitor and protect endangered species in Africa. Researchers from Australian National Univ. and Univ. of Sydney are testing a drone designed to track small wildlife that moves through rugged and inaccessible terrain.

Researchers identify electrifying solution to sticky problem

August 25, 2015 12:10 pm | by Nanyang Technological University | News | Comments

Inspired by the limitations of biomimetic glues in wet environments, scientists have invented a glue that will harden when a voltage is applied to it. The new adhesive, nicknamed "Voltaglue," opens up a host of possible practical applications, from making underwater repair works for ships and pipes, to being a versatile tool for doctors performing surgery.

Scientists find new way to detect ortho-para conversion in water

August 25, 2015 11:36 am | by University of Southampton | News | Comments

New research has found that water molecules react differently to electric fields, which could provide a new way to study spin isomers at the single-molecule level. Water molecules exist in two forms or ‘isomers,’ ortho and para, with different nuclear spin states. In ortho-water, nuclear spins are parallel to one another, and in para water, spins are antiparallel.

How long does it take an electron to tunnel?

August 25, 2015 11:17 am | by Forschungsverbund Berlin e.V. (FVB) | News | Comments

The combination of ab-initio numerical experiments and theory shows that optical tunneling of an electron from an atom can occur instantaneously. How long does it take an atom to absorb a photon and loose an electron? And what if not one but many photons are needed for ionization? How much time would absorption of many photons take? These questions lie at the core of attosecond spectroscopy.

Record high pressure squeezes secrets out of osmium

August 25, 2015 11:06 am | by Deutsches Elektronen-Synchrotron DESY | News | Comments

An international team of scientists has created the highest static pressure ever achieved in a lab: Using a special high pressure device, the researchers investigated the behavior of the metal osmium at pressures of up to 770 Gigapascals (GPa)—more than twice the pressure in the inner core of the Earth, and about 130 Gigapascals higher than the previous world record set by members of the same team.

A team of researchers developing a bioinorganic hybrid approach to artificial photosynthesis have achieved another milestone. Having generated quite a buzz with their hybrid system of semiconducting nanowires and bacteria that used electrons to synthesize carbon dioxide into acetate, the team has now developed a hybrid system that produces renewable molecular hydrogen and uses it to synthesize carbon dioxide into methane.

Discovered in a small quarry on a farm in South Africa’s Free State province, Pulanesaura eocollum is a new member of the long-necked sauropod lineage of dinosaurs. Blair McPhee, a PhD student at the Univ. of Witwatersrand, Johannesburg, along with colleagues, described the new dinosaur in Scientific Reports.
