Public Release: 23-May-2013
Hubble reveals the Ring Nebula's true shape The Ring Nebula's distinctive shape makes it a popular illustration for astronomy books. But new observations by NASA's Hubble Space Telescope of the glowing gas shroud around an old, dying, sun-like star reveal a new twist.

 CellScientists discover how rapamycin slows cell growth University of Montreal researchers have discovered a novel molecular mechanism that can potentially slow the progression of some cancers and other diseases of abnormal growth. In the May 23 edition of the prestigious journal Cell, scientists from the University of Montreal explain how they found that the anti-cancer and anti-proliferative drug rapamycin slows down or prevents cells from dividing.

Lab on a ChipCradle turns smartphone into handheld biosensor Researchers and physicians in the field could soon run on-the-spot tests for environmental toxins, medical diagnostics, food safety and more with their smartphones. University of Illinois researchers have developed a cradle and app for the iPhone that uses the phone's built-in camera and processing power as a biosensor to detect toxins, proteins, bacteria, viruses and other molecules. Although the cradle holds only about $200 of optical components, it performs as accurately as a large $50,000 spectrophotometer in the laboratory. Contact: Liz Ahlberg

ScienceUniversity of Illinois biophysicists measure mechanism that determines fate of living cells For the first time, biophysicists at the University of Illinois at Urbana-Champaign have measured the molecular force required to mechanically transmit function-regulating signals within a cell. A new laboratory method, named the tension gauge tether approach, has made it possible to detect and measure the mechanics of the single-molecule interaction by which human cell receptors are activated.

NASA's SDO observes mid-level solar flare The sun emitted a mid-level solar flare on the morning of May 22, 2013. The flare peaked at 9:38 a.m. EDT and was classified as an M7. M-class flares are the weakest flares that can still cause some space weather effects near Earth. In the past, they have caused brief radio blackouts at the poles.

NASA's Landsat satellite looks for a cloud-free view For decades, Landsat satellites have documented the desiccation of the Aral Sea in Central Asia. Once one of the largest seas in the world, it shrunk to a tenth of its original volume after Russia diverted its feeder rivers in the 1960s. Scientists studying the Aral Sea's changing ecology and retreating shoreline have looked to Landsat -- and a new feature of the Landsat Data Continuity Mission will help ensure they get a clear, cloud-free view.

Tests lead to doubling of fuel cell life Researchers working to improve durability in fuel cell powered buses have discovered links between electrode degradation processes and bus membrane durability. The team is quantifying the effects of electrode degradation stressors in the operating cycle of the bus on the membrane lifetime. The findings of the study are the latest in a long-term study at Burnaby-based Ballard Power Systems funded by Automotive Partnership Canada aiming to make fuel cell buses competitive with diesel hybrids.

New England Journal of MedicineNLST: CT detects twice as many lung cancers as X-ray at initial screening exam Low-dose CT scans detected twice as many early-stage lung cancers as chest X-ray on initial screening exam, according to additional National Lung Screening Trial results. Investigators say the 20 percent lung cancer mortality reduction previously reported in the NLST is achievable at experienced screening centers in the United States.

Journal of Controlled ReleaseResearch offers promising new approach to treatment of lung cancer Researchers have developed a new drug delivery system that allows inhalation of chemotherapeutic drugs to help treat lung cancer, and in laboratory and animal tests it appears to reduce the systemic damage done to other organs while significantly improving the treatment of lung tumors -- the tumors virtually disappeared.

ACS Chemical BiologyOvercoming resistance to anti-cancer drugs by targeting cell 'powerhouses' Re-routing anti-cancer drugs to the "power plants" that make energy to keep cells alive is a promising but long-neglected approach to preventing emergence of the drug-resistant forms of cancer -- source of a serious medical problem, scientists are reporting. That's the conclusion of a new study published in the journal ACS Chemical Biology. Contact: Michael Bernstein

Scientific ReportsNew technique may open up an era of atomic-scale semiconductor devices Researchers at North Carolina State University have developed a new technique for creating high-quality semiconductor thin films at the atomic scale -- meaning the films are only one atom thick. The technique can be used to create these thin films on a large scale, sufficient to coat wafers that are two inches wide, or larger.

Nature NanotechnologyWhirlpools on the nanoscale could multiply magnetic memory Research at Lawrence Berkeley National Laboratory's Advanced Light Source promises four-bit magnetic cells instead of the two-bit magnetic domains of standard magnetic memories. Magnetic vortices are whirlpools of magnetic field, in which electron spins point either clockwise or counterclockwise. In the crowded center of the whirlpool the spins point either down or up. These four orientations could represent separate bits of information in a new kind of memory, if controlled independently and simultaneously.
