Failed dwarf galaxy survives galactic collision thanks to full dark-matter jacket

Posted: 23 May 2014 11:51 AM PDT

Like a bullet wrapped in a full metal jacket, a high-velocity hydrogen cloud hurtling toward the Milky Way appears to be encased in a shell of dark matter, according to a new analysis. Astronomers believe that without this protective shell, the high-velocity cloud known as the Smith Cloud would have disintegrated long ago when it first collided with the disk of our Galaxy.

Nature inspires drones of the future

Posted: 23 May 2014 06:42 AM PDT

Researchers have been taking tips from nature to build the next generation of flying robots. Based on the mechanisms adopted by birds, bats, insects and snakes, scientists have developed solutions to some of the common problems that drones could be faced with when navigating through an urban environment and performing novel tasks for the benefit of society.

Mapping atherosclerotic arteries: Combined approach developed

Posted: 23 May 2014 06:42 AM PDT

A new method allows calcified and constricted blood vessels to be visualized with micrometer precision, and can be used to design containers for targeted drug delivery. Within the project, materials scientists combined cutting-edge-imaging techniques to visualize and quantify the constrictions caused by atherosclerosis.

New sensor could light the way forward in low-cost medical imaging

Posted: 23 May 2014 05:29 AM PDT

A new type of light sensor that could allow medical and security imaging via low cost cameras has been developed by researchers. Near infrared light can be used to perform non-invasive medical procedures, such as measuring the oxygen level in tissue and detecting tumors. It is also already commonly used in security camera systems and for quality control in the agriculture and food industry.

Kidney dialysis machine invented for babies, safely treat newborn with multiple organ failure in world first breakthrough

Posted: 23 May 2014 05:28 AM PDT

A miniaturized kidney dialysis machine capable of treating the smallest babies has been invented, and for the first time, it has been used to safely treat a newborn baby with multiple organ failure. This technology has the potential to revolutionize the treatment of infants with acute kidney injury, according to new research published.

Capillary device significantly improves manufacture of quality liposomes

Posted: 21 May 2014 06:51 AM PDT

Widespread application for the manufactured vesicles known as liposomes has been hindered by limiting factors such as size inconsistency, structural instability and high production costs. A new approach overcomes these obstacles. The group's novel system is made up of bundled capillary tubes, costs less than a $1 to make and requires no special fabrication technology or expertise, yet consistently yields large quantities of uniform and sturdy vesicles.
