NASA's Tropical Rainfall Measuring Mission (TRMM) satellite has scanned rainfall rates, and NASA's Aqua satellite has provided a look at cloud temperatures which indicates where the strongest thunderstorms and heaviest rainfall is occurring.
The TRMM satellite saw the intensifying storm on May 22, 2012 at 1535 UTC when wind speeds had reached to over 45 knots (~52 mph). Data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments show that Sanvu had a very large area of heavy rainfall wrapping around the northeastern side. TRMM's PR also shows that the highest convective storm towers, reaching to heights above 16km (~9.9 miles), were in a feeder band on the southeastern side.On May 23, the TRMM passed over Sanvu again after it had strengthened further, and captured more data. That data was used to create another 3-D analysis at NASA's Goddard Space Flight Center in Greenbelt, Md. The 3-D image created from TRMM PR data revealed that an eye was almost formed indicating that Sanvu may soon be a typhoon. Several towers in the forming eye wall extend to heights above 16km (~9.94 miles). These towers contain the heaviest rains and act to energize the core of the storm.
Infrared satellite imagery from NASA's Atmospheric Infrared Sounder (AIRS) instrument onboard NASA's Aqua satellite showed that Sanvu's feeder bands were mostly on the eastern side of the center of circulation and have become more tightly wrapped around the center. Those thunderstorms within the feeder bands have also strengthened. The strongest storms have a cloud top temperature colder than -63F (-52C) indicating they are high in the troposphere and powerful.
Sanvu is predicted to intensify further and become the first western Pacific typhoon of 2012. One factor that is helping Sanvu continue to intensify is the warm sea surface temperatures at 86 degrees Fahrenheit (30 Celsius).
The current forecast track takes it just east of Iwo To and Chichi Jima, which may experience typhoon conditions on May 25 and 26, respectively.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
