NASA HS3 mission Global Hawk's bullseye in Hurricane Edouard
NASA's Hurricane Severe Storms Sentinel or HS3 mission flew the unmanned Global Hawk aircraft on two missions between Sept. 11 and 15 into Hurricane Edouard and scored a bullseye by gathering information in the eye of the strengthening storm. Scientists saw how upper-level wind shear was affecting Edouard on the HS3's Global Hawk flight of the 2014 campaign over Sept. 11 and 12, and saw the hurricane strengthen during the sixth flight on Sept. 15 and 16.

Synthetic biology on ordinary paper, results off the page
Two breakthroughs clenched by Wyss scientists, paper–based synthetic gene networks and toehold switch gene regulators, could each have revolutionary impacts on synthetic biology: the former brings synthetic biology out of the traditional confinement of a living cell, the latter provides a rational design framework to enable de-novo design of both the parts and the network of gene regulation

Study: Some online shoppers pay more than others
A new study co-authored by a team of Northeastern University faculty and students has found numerous instances of price steering and discrimination on many popular e-commerce retail and travel websites. That's not necessarily a bad thing, they say -- so long as the companies are transparent.

NASA's Terra satellite shows a more organized Tropical Storm Ana
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.

NYU researchers break nano barrier to engineer the first protein microfiber
Researchers have broken new ground in the development of proteins that form specialized fibers used in medicine and nanotechnology. For as long as scientists have been able to create new proteins that are capable of self-assembling into fibers, their work has taken place on the nanoscale. For the first time, this achievement has been realized on the microscale -- a leap of magnitude in size that presents significant new opportunities for using engineered protein fibers.

'Watch' cites concern about flexible reamer breakage during anatomic ACL reconstruction
JBJS Case Connector, an online case journal published by the Journal of Bone and Joint Surgery, has issued a 'Watch' regarding concerns over flexible reamer breakage during anatomic single-bundle ACL reconstruction. Flexible reamers help surgeons achieve optimal femoral-tunnel parameters, but they are prone to breakage in certain situations, as the 'Watch' article explains.

Sea turtles' first days of life: A sprint and a ride towards safety
With new nano-sized acoustic transmitters, scientists from GEOMAR Helmholtz Centre for Ocean Research Kiel, the Turtle Foundation and Queen Mary University of London followed the pathways of loggerhead turtle hatchlings. According to the study, which was primarily funded by the Kiel Cluster of Excellence 'The Future Ocean,' local oceanic conditions are believed to drive the evolution of some unique swimming behaviors. The results are published in the Proceedings of the Royal Society B.

Waste, an alternative source of energy to petroleum
The group led by Martín Olazar, researcher in the UPV/EHU's Department of Chemical Engineering, is studying the development of sustainable refineries where it is possible to produce fuels and raw materials providing an alternative to petroleum by using biomass and other waste materials like plastics, tires, etc. Conical spouted beds are the key to the high energy efficiency of these refineries.

RF heating of magnetic nanoparticles improves the thawing of cryopreserved biomaterials
Successful techniques for cryopreserving bulk biomaterials and organ systems would transform current approaches to transplantation and regenerative medicine. However, while vitrified cryopreservation holds great promise, practical application has been limited to smaller systems (cells and thin tissues) due to diffusive heat and mass transfer limitations, which are typically manifested as devitrification and cracking failures during thaw. Here we leverage a clinically proven technology platform, in magnetically heated nanoparticles, to overcome this major hurdle limiting further advancement in the field of cryopreservation.

New microscope collects dynamic images of the molecules that animate life
A new microscopy technology collects high-resolution images rapidly and minimizes damage to cells, meaning it can image the 3-D activity of molecules, cells, and embryos in fine detail over longer periods than was previously possible. Developed at Howard Hughes Medical Institute's Janelia Research Campus, the microscope enables cell and molecular biologists to produce stunning videos of biological processes across a range of sizes and time scales, from the movements of individual proteins to the development of entire animal embryos.

NASA-NOAA Suomi NPP Satellite team ward off recent space debris threat
Space debris, also known as 'space junk,' is an ongoing real-life concern for teams managing satellites orbiting Earth, including NOAA-NASA's Suomi National Polar-orbiting Partnership, or Suomi NPP, satellite. It is not unusual for satellites that have the capability of maneuvering to be repositioned to avoid debris or to maintain the proper orbit.

Strengthening thin-film bonds with ultrafast data collection
When studying extremely fast reactions in ultrathin materials, two measurements are better than one. A new research tool invented by researchers at Lawrence Livermore National Laboratory, Johns Hopkins University and NIST captures information about both temperature and crystal structure during extremely fast reactions in thin-film materials.

NIST offers electronics industry 2 ways to snoop on self-organizing molecules
The idea of a practical manufacturing process based on getting molecules to organize themselves in useful nanoscale shapes once seemed a little fantastic. Now the day isn't far off when your cell phone may depend on it. Two recent papers by researchers at NIST, MIT and IBM demonstrate complementary approaches to 3-D imaging of nanoscale polymer patterns for use in semiconductor lithography.

Paralyzed patients have weaker bones and a higher risk of fractures than expected
People paralyzed by spinal cord injuries lose mechanical strength in their leg bones faster, and more significantly, than previously believed, putting them at greater risk for fractures from minor stresses, according to a study by researchers at Worcester Polytechnic Institute. The results suggest that physicians should begin therapies for such patients sooner to maintain bone mass and strength, and should think beyond standard bone density tests when assessing fracture risk in osteoporosis patients.

New tool identifies high-priority dams for fish survival
Scientists have identified 181 California dams that may need to increase water flows to protect native fish downstream. The screening tool, developed by the Center for Watershed Sciences at the University of California, Davis, to select 'high-priority' dams may be particularly useful during drought years amid competing demands for water.
