Following what it describes as an "exhaustive and rigorous scientific review," the US Food and Drug Administration (FDA) today announced the approval of the first ever genetically-modified animal for human consumption. The engineered salmon in question has had its DNA altered in such a way that it grows to market-ready size in around half the time of regular salmon, and has now been declared safe for humans and safe for the environment.
Fish farming seems like a great idea on paper. But a host of environmental problems can plague coastal fisheries, most due to the large amounts of waste generated by these floating factory farms. eFishery, a company based in Indonesia and run with the involvement of TED Prize director Amy Novogratz, hopes to alleviate waste problems that result from both over and underfeeding of fish with the development of a smart feeding device that bases the amount of feed dispensed on fish behaviour.
Researchers from the University of California, San Diego (UCSD) are taking inspiration from nature in the search for new materials that could one day be used to create body armor. The study, supported by the US Air Force, focuses on the unique structure and strength of the hexagonally-scaled shell of the boxfish.
If you happen to be frolicking around in some tropical waters at some point in the future, you may have the marine life circling your feet to thank for keeping your shoulders from roasting. Scientists have uncovered a technique used by zebrafish and various other animals to create their own sunscreen and recreated it in the lab. They say the method could one day be used to produce sunscreen and other pharmaceuticals for humans.
We frequently hear that eating fish is a healthy thing to do, because
it's full of beneficial long chain fatty acids. Unfortunately, the
Western diet tends to be short on fish and bigger on beef, which
contains short chain fatty acids that aren't quite so good for us.
Chinese scientists are creating a work-around, however –
genetically-engineered beef that's high in the "good" fatty acids.
Mussels have an incredible ability to cling to wet surfaces. It's an ability that scientists are trying to replicate
for use in man-made adhesives. That adhesion can't be turned on and off
as needed, however, limiting its potential applications. That's where
the Northern clingfish comes in. It can suck onto rough, slimy surfaces,
supporting up to 150 times its own body weight when lifted. That said,
it can also just let go and swim away whenever it wants. Scientists from
the University of Washington now understand how it's able to do so, and
are looking at applying the principle to fields such as surgery and
