Hubble stirs up galactic soup Posted: 16 Aug 2014 12:48 PM PDT A new NASA/ESA Hubble Space Telescope image shows a whole host of colorful and differently shaped galaxies; some bright and nearby, some fuzzy, and some so far from us they appear as small specks in the background sky. Together they appear as kind of galactic soup.

Students see world from station crew's point of view Posted: 16 Aug 2014 12:43 PM PDT NASA is helping students examine their home planet from space without ever leaving the ground, giving them a global perspective by going beyond a map attached to a sphere on a pedestal. The Sally Ride Earth Knowledge Acquired by Middle School Students (Sally Ride EarthKAM) program provides a unique educational opportunity for thousands of students multiple times a year.

U.S. commercial cargo ship delivery mission ends as Canadarm2 releases Cygnus Posted: 16 Aug 2014 12:41 PM PDT Orbital Sciences Cygnus commercial cargo craft completed a month-long delivery mission to the International Space Station Friday when it was released from the grips of the Canadarm2 robotic arm at 6:40 a.m. EDT. Cygnus is now orbiting on its own, separating from the station and heading for a deorbit and a fiery entry over the Pacific Ocean on Sunday.

Curiosity Mars rover prepares for fourth rock drilling Posted: 16 Aug 2014 12:38 PM PDT The team operating NASA's Curiosity Mars rover has chosen a rock that looks like a pale paving stone as the mission's fourth drilling target, if it passes engineers' evaluation. They call it "Bonanza King."

NASA's Chandra Observatory searches for trigger of nearby supernova Posted: 16 Aug 2014 12:34 PM PDT New data from NASA's Chandra X-ray Observatory offer a glimpse into the environment of a star before it exploded earlier this year, and insight into what triggered one of the closest supernovas witnessed in decades.

As seen by Rosetta: Comet surface variations Posted: 16 Aug 2014 10:21 AM PDT A new image of comet 67P/Churyumov-Gerasimenko shows the diversity of surface structures on the comet's nucleus. It was taken by the Rosetta spacecraft's OSIRIS narrow-angle camera on August 7, 2014. At the time, the spacecraft was 65 miles (104 kilometers) away from the 2.5-mile-wide (4-kilometer) nucleus.

Giving credit where credit is due: Credit allocation among researchers determined by new algorithm Posted: 15 Aug 2014 04:25 PM PDT A new algorithm may help to accurately allocate credit to authors on multi-author papers across disciplines. Using the algo­rithm, the team revealed a new credit allo­ca­tion system based on how often the paper is co-cited with the other papers pub­lished by the paper's co-authors, cap­turing the authors' addi­tional con­tri­bu­tions to the field.

Researchers develop defense against cyberattacks Posted: 15 Aug 2014 07:23 AM PDT A group of journalists has reported the existence of the 'Hacienda' spy program. According to this report, five western intelligence agencies are using the Hacienda software to identify vulnerable servers across the world in order to control them and use them for their own purposes. Scientists have now developed free software that can help prevent this kind of identification and thus the subsequent capture of systems.

The beetle's white album: Beetle shells could inspire brighter, whiter coatings and materials Posted: 15 Aug 2014 07:22 AM PDT The physical properties of the ultra-white scales on certain species of beetle could be used to make whiter paper, plastics and paints, while using far less material than is used in current manufacturing methods.

Key upgrade to genomics software will underpin global data sharing Posted: 15 Aug 2014 07:21 AM PDT The rapidly rising volume of genomic data means that genomic scientists need fast and efficient methods to share, analyse and store sequence information. A major upgrade of Samtools, one of the most popular next-generation sequence analysis tools, now supports the highly efficient CRAM format, enabling researcher to easily compress and share their data, reducing costs and facilitating worldwide collaboration.

Novel lung-on-a-chip developed Posted: 14 Aug 2014 04:12 PM PDT A new lung-on-chip microdevice for laboratory studies of respiratory challenges and therapeutics has been developed by scientists. The microdevice includes multiple vertically stacked cellular layers that mimic the structure of the airway tissue. The cellular model of the airway mucosa could provide insight into biological and pathophysiological effects that conventional cell cultures or animal models do not capture, and help lead to the development of new therapeutics.

Inside the cell, an ocean of buffeting waves, contrary to conventional understanding Posted: 14 Aug 2014 09:38 AM PDT Conventional wisdom holds that the cytoplasm of mammalian cells is a viscous fluid, with organelles and proteins suspended within it, jiggling against one another and drifting at random. However, a new biophysical study challenges this model and reveals that those drifting objects are subject to a very different type of environment. The cytoplasm is actually an elastic gel, it turns out, so it puts up some resistance to simple diffusion, researchers report.
