Small is beautiful in hydroelectric power plant design, and good for...

Hydroelectric power is the oldest and the "greenest" source of renewable energy. In Germany, the potential would appear to be completely exploited, while large-scale projects in developing countries are eliciting strong criticism due to their ma...

Computational model of swimming fish could inspire design of robots or...

Scientists at the University of Maryland and Tulane University have developed a computational model of a swimming fish that is the first to address the interaction of both internal and external forces on locomotion. The interdisciplinary research ...

Fish oil linked to increased risk of colon cancer in mice

EAST LANSING, Mich. -- Fish oil -- long encouraged by doctors as a supplement to support heart and joint health, among other benefits -- induced severe colitis and colon cancer in mice in research led by Michigan State University and published t...

‘Gold’ fish thrive, cancers die

Rice University physicist Dmitri Lapotko has demonstrated that plasmonic nanobubbles, generated around gold nanoparticles with a laser pulse, can detect and destroy...

Female fish abandoned by males to raise offspring on their own

Caring for children can be a tough job, particularly if you are a female cichlid fish. Native to the crater lakes of Nicaragua, cichlid fish look after their young by defending them against would-be predators. While male and female cichlid fish g...

Progress on vaccine for ‘Ich,’ bane of fish farms and home...

Tests of a potential vaccine against "Ich" -- the dreaded "white-spot" disease that plagues fish in commercial fish farms, public aquariums, pet fish retail outlets, and home aquariums -- are raising hopes for finally controlling the disease, sc...

Global fisheries research finds promise and peril

Global fisheries, a vital source of food and revenue throughout the world, contribute between US$225-$240 billion per year to the worldwide economy, according to four new studies released today. Researchers also concluded that healthier fisheries co...

Ending the oceans’ ‘tragedy of the commons’

Leading international marine scientists are proposing radical changes in the governance of the world's oceans to rescue them from overfishing, pollution and other human impacts. Based on a successful experiment in Chile, the researchers say a new ...

Salmon baby food? Babies need omega-3s and a taste for fish,...

URBANA -- Has your toddler eaten fish today? A University of Illinois food science professor has two important reasons for including seafood in your young child's diet, reasons that have motivated her work in helping to develop a tasty, nutritious ...

Researchers mimic fish for new underwater vehicle

Researchers have developed an artificial neural network for use with an autonomous underwater vehicle named Fetch. Characteristics of different fish species were compiled using the side scan sonar data. This information was then grouped into test sets used for training artificial neural networks (ANNs). The team combined the use of enhancement algorithms and image processing, in conjunction with the ANNs, to "teach" the computer to recognize the characteristics of various fish species.
