A study by five university researchers—including four from the University of Hawai'i at Mânoa—concludes that existing shark cage diving enterprises in Hawai'i have a negligible effect on public safety.
The paper, "Seasonal cycles and long-term trends in abundance and species composition of sharks associated with cage diving ecotourism activities in Hawai'i," is authored by Carl G. Meyer, Jonathan J. Dale, Yannis P. Papastamatiou, Nicholas M. Whitney and Kim N. Holland, and has been published in the online section of the Environmental Conservation journal.
Meyer, Dale, Papastamatiou and Holland are researchers with the UH Mânoa Hawai'i Institute of Marine Biology at Coconut Island, while Whitney works at the Mote Marine Laboratory in Sarasota, Florida.
The scientists collected and analyzed logbook data from two O'ahu shark cage diving operations from 2004-08 to obtain "useful insights into shark ecology or ecotourism impacts." Those impacts on public safety were deemed to be "negligible," due to factors such as remoteness of the sites, and conditioning stimuli that are specific to the tour operations and different from inshore recreational stimuli.
The study also notes that there has been "no increase in shark attacks on the north coast of O'ahu since cage diving started."

The University of Hawai`i at Mânoa serves approximately 20,000 students pursuing 225 different degrees. Coming from every Hawaiian island, every state in the nation, and more than 100 countries, UH Mânoa students matriculate in an enriching environment for the global exchange of ideas.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
