This study investigated the effect of seaweed supplementation in dairy cow diets on milk yield, basic composition, and mineral concentrations. Thirty-seven Icelandic cows were split into three diet treatments: control (CON, no seaweed), low seaweed (LSW, 0.75% concentrate dry matter (DM), 13–40 g / cow / day), and high seaweed (HSW, 1.5% concentrate DM, 26–158 g / cow / day). Cows were fed the same basal diet of grass silage and concentrate for a week, and then were introduced to the assigned experimental diets for 6 weeks. The seaweed mix of 91% Ascophyllum nodosum: 9% Digital Laminaria (DM basis), feed, and milk samples were collected weekly. Data were analyzed using a linear mixed effects model, with diet, week, and their interaction as fixed factors, cow ID as random factor, and the pre-treatment week data as a covariate. When compared with CON milk, LSW and HSW milk had, respectively, less Se (−1.4 and −3.1 μg / kg milk) and more I (+744 and +1649 μg / kg milk), while HSW milk also had less Cu ( −11.6 μg / kg milk) and more As (+0.17 μg / kg milk) than CON milk. The minimal changes or concentrations in milk for Se, Cu, and As can not be associated with any effects on consumer nutrition, but care should be taken when I-rich seaweed is fed to cows to avoid excessive animal I supply and milk I concentrations.

The television crew from France accompanied Matís staff up to the eruption at Fagradalsfjall. The expedition was part of the project AirMicrome examining the fate of airborne micro-organisms as the first settlers in terrestrial communities.
The TV crew from France TV captured great videos of the eruption and talked to Pauline Vannier from Matís, who led the team around the area and explained the project in a rough outline.
The video can be found here. The discussion about AirMicrome starts on min. 7:30.
The purpose of the Inspire summer schools under the auspices of EIT Food is to train students and young people in the labor market in innovation and to become entrepreneurs. Students will be trained in product development and business planning for new ideas and new opportunities related to current global food issues. In this way, they are prepared to face the challenges and changes that lie ahead in food production in the coming decades. In 2021, 6 summer schools will be offered, each of which will take about 3 weeks. Matís will take part in summer schools about aquaculture and new protein sources in food that take place in late summer.
Applications have already been opened for summer school for new protein sources of the future!
We encourage master's and doctoral students to study summer school alone and draw attention to the fact that most universities value these courses as 4 ECTS credits.

Protein for Future - summer school 2021.
Do you want to develop new ideas on the future proteins in our diet to counteract some of the causes of climate change through entrepreneurial capacity training in a 3 week summer school starting August 16th and ending September 3rd?
You will be taught how new and alternative proteins, like plant, cell and insect based proteins, can be integrated in our food systems. You will work and be coached in teams. You will end up in new business ideas that will be pitched in front of professional jury. Critical questions on how to develop a sustainable future food system will be addressed. How can new and alternative food proteins be integrated into our food systems? What are the technological obstacles, and what are the regulatory and consumer / market related barriers? How do we design and develop alternative proteins and how can we develop and formulate alternative protein based food products.

Oddur Már Gunnarsson, CEO of Matís, Þorsteinn Sigurðsson, CEO of the Marine Research Institute and Kristján Þór Júlíusson, Minister of Fisheries and Agriculture, set out with an escort east to land on 16 June. The reason for the trip was a visit to Múlinn in Neskaupstaður. It was decided to make good use of the trip and visit some of the main workplaces in the East Fjords.
The first place the party visited was Eskja's new and magnificent pelagic processing plant in Eskifjörður. Þorstein Kristjánsson, CEO of Eskja, led an informative tour with others about the building, which is huge and high-tech. Next was held at Egersund in Iceland, which is also located in Eskifjörður. Egersund is a leading company in the field of sales, fishing gear manufacturing and repair of float trawls and seines and the group got to know people in the various jobs.
Next, the company Laxar fiskeldi was visited and held out in the fish farms of those located in Reyðarfjörður. The docks were inspected and Jens Garðar Helgason, managing director, along with other staff also offered a cup of coffee outside in a barge which was welcome in the sleet which did not fit well with the date on the calendar. The visit to Eskifjörður was crowned with lunch at Randulffssjóhús.
In the afternoon we visited Norðfjörður and visited Múlinn, a cooperative house in Neskaupstaður. Many staff gathered in Múlan and the group from the south was given a tour of the house, which is all the most magnificent. The Minister addressed the meeting at the beginning and Oddur Már and Þorsteinn Sigurðsson did the same. Stefán Þór Eysteinsson finally told about the construction and infrastructure of a new biomass plant that Matís is setting up on site in collaboration with Síldarvinnslan.
After the ceremony in Múlan, Börkur, Síldarvinnslan's new ship, was inspected. Gunnþór B. Ingvason, CEO of Síldarvinnslan, guided the group around the ship and told about the infrastructure that is one of the most perfect that happens.
The trip was all the most enjoyable and it is clear that the possibilities for collaboration with companies in the Eastfjords are many and varied.
