Attaching Fitbits to Port Jackson Sharks to observe their behaviour
A group of scientists has just discovered how modern technology can be used to study sharks out in the open. The researchers wanted to gain an understanding of shark behaviour and their whereabouts in order to reduce the amount and risk of human-shark interactions. Now, Macquarie scientist Julianna Kadar has just found the best method of using tagging technology to do just that. The researchers gathered Port Jackson sharks from the wild and attached a Fitbit like device ? acoustic accelerometers ? on the sharks to monitor their movements. The data collected by this new technology has since confirmed new information about the breed.
Bringing Electricity to Disaster Zones Zéphyr is a photovoltaic balloon and eco-friendly generator created by Karen Assaraf, Julie Dautel, and Cédric Tomissi. The balloon only requires water in order to inflate and can capture solar energy from as high as 165 feet (50 meters) in the air. The balloon is connected by a cable to a base, where the energy is stored. Its creators hope that it will bring power to areas struck by natural disasters
