If ingested, for example in seafood, these toxins can lead to discomfort or even illness. The algatoxin yessotoxin (YTX), which is found in both mussels and scallops in Norway, may be a potential disease risk factor in the consumption of seafood. “We don’t know the long-term effects of YTX on people”, says Mónica Suárez Korsnes of the Norwegian School of Veterinary Science (NVH).
Suárez Korsnes has studied the effects of YTX on muscle cell lines from mice and rats.
“We know that an injection of YTX into the abdomen of animals damages heart muscle. To date, YTX intoxication has never been recorded in people, however, we suspect that long-term exposure to this toxin may lead to damage in humans”, says Suárez Korsnes.
The aim of this research is to establish a basic understanding of the ways in which YTX affects cells in the body. Suárez Korsnes has, in her doctoral work, shown that exposure to YTX can initiate a type of programmed cell death, called apoptosis.
“Apoptosis is a method that the body uses to rid itself of unwanted cells. Some toxins, for example YTX, seem to disrupt this natural mechanism and thereby damage organisms”, explains Suárez Korsnes.
Quality control of seafood
An understanding of how algatoxin can affect organisms is important for the quality control of seafood and for responsible management of marine resources. An increased knowledge of algatoxin may contribute to better surveillance of the food chain and to measures that better protect consumers, producers and exporters of seafood.
More algatoxin than before
During the last few decades, the incidence of algatoxin blooms in the ocean has become more frequent. The reasons for this may include spreading of different types of algae to new seas in the ballast water in ships. Other causes may include increased supply of nutrients from land runoff, and also from the air and rain.
Climatic changes, changes in ocean currents and ecological changes may also explain the increasing prevalence of algatoxin.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
