The strong southwesterly wind shear that has been battering Tropical Storm Ana has abated and has given the storm a chance to re-organize.
Ana appeared more rounded on imagery from NASA's Terra satellite as thunderstorms again circled the low-level center.
NASA's Terra satellite passed over Ana on Oct. 22 at 22:10 UTC (6:10 p.m. EDT). The MODIS instrument aboard Terra captured a visible image of the storm that showed clouds and showers were no longer being blown northeast of the center from southwesterly wind shear, as they had in the last couple of days.
The wind shear has weakened, which allowing for the showers and thunderstorms to redevelop around the center of the storm.
On Oct. 24, Ana was strengthening and moving northwest while crossing the northwest Hawaiian Islands east of Maro Reef.
A Tropical Storm Warning is in effect for portions of the Papahanaumokuakea Marine National Monument, from French Frigate Shoals to Lisianski.
At 8 a.m. (2 a.m. HST/1200 UTC) the center of Tropical Storm Ana was located near latitude 26.0 north and longitude 168.6 west. Ana was moving toward the northwest near 12 mph (19 kph) and this motion is expected to become more northerly through early Friday, then northeasterly through early Saturday, Oct. 25. Maximum sustained winds were near 50 mph (80 kph).
NOAA's Central Pacific Hurricane Center expects Ana to continue strengthening through early Saturday.

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...
