Rosetta's comet lander: How (and where) is Philae? Posted: 14 Nov 2014 12:02 PM PST The current status of Rosetta's lander Philae was discussed live during a Google Hangout this afternoon, together with scientists and engineers from the mission teams at ESA and partner agencies. The teams are very happy about the lander and the successful functioning of all instruments that were operated so far.

New imaging technique identifies receptors for targeted cancer therapy Posted: 14 Nov 2014 09:49 AM PST A fluorescence imaging technique has been developed that can more accurately identify receptors for targeted cancer therapies without a tissue biopsy. "Accurately determining the population of protein receptors in a tumor available for targeting by molecular therapies or diagnostic imaging agents can greatly impact oncology patient outcomes," said one investigator. "Our in vivo receptor concentration imaging technique is a novel approach for fluorescence imaging that can potentially impact clinical assessment of tumor status and malignant tissue classification."

Cutting-edge computer software helps pinpoint aggressiveness of breast cancer tumors Posted: 14 Nov 2014 09:49 AM PST Cutting-edge genetic mutation-analysis software is being used to interpret mutations in tumor genomes that may provide insight into determining which breast cancer tumors are more likely spread to other parts of the body and which ones won't.

Smartphones team-up with QR codes for secure 3-D displays Posted: 14 Nov 2014 09:47 AM PST Quick Response (QR) codes -- the box-shaped symbols that appear on signs, posters, and even business cards -- are a convenient and efficient way of accessing specific web pages with a smartphone or other mobile device. However, new research explains how QR codes can do much more.

Proposed 'wide view' Hubble Space Telescope Posted: 14 Nov 2014 09:44 AM PST Scientists are working on a proposed NASA space telescope that will provide images as sharp as the Hubble Space Telescope, but over a hundred times larger area. The space observatory, called the Wide-Field Infrared Survey Telescope-Astrophysics Focused Telescope Assets (WFIRST-AFTA), is being studied for launch in the mid-2020s, pending program approval by NASA.

Portable device for hearing the heart of mother and her baby Posted: 14 Nov 2014 05:56 AM PST A new portable device is able to detect both the electrical activity emitted by the heart of the mom as from the unborn baby's.

Three touchdowns for Rosetta’s lander Posted: 14 Nov 2014 05:56 AM PST After achieving touchdown on a comet for the first time in history, scientists and engineers are busy analyzing this new world and the nature of the landing. They discovered that the lander did not just touch down on Comet 67P/Churyumov-Gerasimenko once, but three times.

Mission to discover hundreds of black holes could unlock secrets of the Universe Posted: 14 Nov 2014 05:56 AM PST Researchers have made a breakthrough in helping scientists discover hundreds of black holes throughout the universe. When two detectors are switched on in the US next year, scientists hope to pick up the faint ripples of black hole collisions millions of years ago, known as gravitational waves. Black holes cannot be seen, but scientists hope the revamped detectors -- which act like giant microphones -- will find remnants of black hole collisions.

Sonar-assisted human navigation Posted: 14 Nov 2014 05:53 AM PST STEM incubator students have developed a device inspired by bat sonar to help those with visual impairment. "We were inspired by bat sonar, we learned about it, and then we used it to develop a new product. The students took the idea and made it happen," their professor has noted.

'Topological insulators' promising for spintronics, quantum computers Posted: 13 Nov 2014 04:51 PM PST Researches have uncovered 'smoking-gun' evidence to confirm the workings of an emerging class of materials that could make possible 'spintronic' devices and practical quantum computers far more powerful than today's technologies.

Chemists develop porous molecules that bind greenhouse gases Posted: 13 Nov 2014 04:51 PM PST Chemistry researchers have developed a molecule that assembles spontaneously into a lightweight structure with microscopic pores capable of binding large quantities of several potent greenhouse gases.

Technology developed to improve lung cancer detection, treatment Posted: 13 Nov 2014 04:49 PM PST A technology that improves the detection of tumors during radiation therapy for early-stage lung cancer has been developed by researchers. Their approach uses dual-energy imaging combined with fluoroscopy to view tumors during radiation therapy. This technology does not require an X-ray that produces both high-and low-energy images.

Intergalactic 'wind' is stripping galaxies of star-forming gas Posted: 13 Nov 2014 12:29 PM PST Astronomers have provided the first direct evidence that an intergalactic 'wind' is stripping galaxies of star-forming gas as they fall into clusters of galaxies. The observations help explain why galaxies found in clusters are known to have relatively little gas and less star formation when compared to non-cluster or 'field' galaxies.

Magnetic fields frozen into meteorite grains tell a shocking tale of solar system birth Posted: 13 Nov 2014 11:21 AM PST Astrophysicists say that magnetic clues in a meteorite outline the earliest steps in the formation of the solar system and Earth-like planets.

Bacteria become 'genomic tape recorders', recording chemical exposures in their DNA Posted: 13 Nov 2014 11:20 AM PST Engineers have transformed the genome of the bacterium E. coli into a long-term storage device for memory. They envision that this stable, erasable, and easy-to-retrieve memory will be well suited for applications such as sensors for environmental and medical monitoring.

Bio-inspired bleeding control: Synthesized platelet-like nanoparticles created Posted: 13 Nov 2014 11:00 AM PST Stanching the free flow of blood from an injury remains a holy grail of clinical medicine. Controlling blood flow is a primary concern and first line of defense for patients and medical staff in many situations, from traumatic injury to illness to surgery. If control is not established within the first few minutes of a hemorrhage, further treatment and healing are impossible. Taking a cue from the human body's own coagulation processes, researchers have synthesized platelet-like nanoparticles that can do more than clot blood.

Promising technology to expand hard cider industry Posted: 13 Nov 2014 11:00 AM PST Mechanical harvesting of cider apples can provide labor and cost savings without affecting fruit, juice, or cider quality, a study shows. The study is one of several focused on cider apple production in Washington State. It was conducted in response to growing demand for hard cider apples in the state and the nation.

Self-repairing software tackles malware Posted: 13 Nov 2014 11:00 AM PST Computer scientists have developed software that not only detects and eradicates never-before-seen viruses and other malware, but also automatically repairs damage caused by them. The software then prevents the invader from ever infecting the computer again.

The party's over for these youthful compact galaxies Posted: 13 Nov 2014 11:00 AM PST Scientists have uncovered young, massive, compact galaxies whose raucous star-making parties are ending early. The firestorm of star birth has blasted out most of the remaining gaseous fuel needed to make future generations of stars. Now the party's over for these gas-starved galaxies, and they are on track to possibly becoming so-called "red and dead galaxies," composed only of aging stars.

New process isolates promising material: Molybdenum disulfide has emerged as a leading successor to graphene Posted: 13 Nov 2014 09:32 AM PST Scientists are working to isolate atomically thin layers of molybdenum disulfide, a material with applications in electronics, optoelectronics, solar cells, and catalysis.

Technology to advance stem cell therapeutics patented Posted: 13 Nov 2014 09:32 AM PST A highly robust, efficient nanoparticle-based platform that can regulate gene expression and eventually stem cell differentiation has been developed by researchers. NanoScript is the first nanomaterial TF protein that can interact with endogenous DNA.

Self-doping may be the key to superconductivity in room temperature Posted: 13 Nov 2014 08:03 AM PST Materials researchers have investigated the superconductor YBCO using advanced X-ray spectroscopy. YBCO is a well-known ceramic copper-based material that can conduct electricity without loss (superconductivity) when it is cooled below its critical temperature Tc=-183° C.
