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. —> Read More Here

Researchers highlight acousto-optic tunable filter technology for balloon-borne platforms

A balloon-borne acousto-optic tunable filter hyperspectral imager is ideally suited to address numerous outstanding questions in planetary science. Their spectral agility, narrowband wavelength selection, tolerance to the near-space environment, and spectral coverage would enable investigations not feasible from the ground. Example use cases include synoptic observations of clouds on Venus and the giant planets, studies of molecular emissions from cometary comae, the mapping of surface ices on small bodies, and polarimetry. —> Read More Here

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. —> Read More Here

Dispositional mindfulness associated with better cardiovascular health

A new study that measured ‘dispositional mindfulness’ along with seven indicators of cardiovascular health found that persons reporting higher degrees of awareness of their present feelings and experiences had better health. The research suggests that interventions to improve mindfulness could benefit cardiovascular health, an idea researchers can test. —> Read More Here

Chamber of secrets

Cells can huddle to communicate within a restricted group, scientists at EMBL Heidelberg have found. The study is the first demonstration that the way cells organize themselves influences their ability to communicate. The researchers propose that this strategy, which they discovered in developing zebrafish, could be much more widespread, influencing processes like wound repair, organ formation and even cancer. —> Read More Here

‘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. —> Read More Here
