- Ilinx is a multidisciplinary art/science research project focusing on the development of a multisensory art installation involving sound, visuals and haptics. In this paper we describe design choices and technical challenges behind the development of the haptic technology embedded into six augment garments. Starting from perceptual experiments, conducted to characterize the thirty vibrating actuators used in the garments, we describe hardware and software design, and the development of several haptic effects. The garments have successfully been used by over 300 people during the premiere of the installation in the TodaysArt 2014 festival in The Hague.

- The Nordic Centre of Excellence CRAICC (Cryosphere-Atmosphere Interactions in a Changing Arctic Climate), funded by NordForsk in the years 2011-2016, is the largest joint Nordic research and innovation initiative to date, aiming to strengthen research and innovation regarding climate change issues in the Nordic region. CRAICC gathered more than 100 scientists from all Nordic countries in a virtual centre with the objectives of identifying and quantifying the major processes controlling Arctic warming and related feedback mechanisms, outlining strategies to mitigate Arctic warming, and developing Nordic Earth system modelling with a focus on short-lived climate forcers (SLCFs), including natural and anthropogenic aerosols. The outcome of CRAICC is reflected in more than 150 peer-reviewed scientific publications, most of which are in the CRAICC special issue of the journal Atmospheric Chemistry and Physics. This paper presents an overview of the main scientific topics investigated in the centre and provides the reader with a state-of-the-art comprehensive summary of what has been achieved in CRAICC with links to the particular publications for further detail. Faced with a vast amount of scientific discovery, we do not claim to completely summarize the results from CRAICC within this paper, but rather concentrate here on the main results which are related to feedback loops in climate change-cryosphere interactions that affect Arctic amplification.

The subpolar gyre regulates silicate concentrations in the North Atlantic
- 2017

Tidskriftsartikel (refereegranskat)abstract
- The North Atlantic is characterized by diatom-dominated spring blooms that results in significant transfer of carbon to higher trophic levels and the deep ocean. These blooms are terminated by limiting silicate concentrations in summer. Numerous regional studies have demonstrated phytoplankton community shifts to lightly-silicified diatoms and non-silicifying plankton at the onset of silicate limitation. However, to understand basin-scale patterns in ecosystem and climate dynamics, nutrient inventories must be examined over sufficient temporal and spatial scales. Here we show, from a new comprehensive compilation of data from the subpolar Atlantic Ocean, clear evidence of a marked pre-bloom silicate decline of 1.5-2 mu M throughout the winter mixed layer during the last 25 years. This silicate decrease is primarily attributed to natural multi-decadal variability through decreased winter convection depths since the mid-1990s, a weakening and retraction of the subpolar gyre and an associated increased influence of nutrient-poor water of subtropical origin. Reduced Arctic silicate import and the projected hemispheric-scale climate change-induced weakening of vertical mixing may have acted to amplify the recent decline. These marked fluctuations in pre-bloom silicate inventories will likely have important consequences for the spatial and temporal extent of diatom blooms, thus impacting ecosystem productivity and ocean-atmosphere climate dynamics.

- Lymphocyte-based immunotherapy has emerged as a break-through in cancer therapy for both hematologic and solid malignancies. In a subpopulation of cancer patients, this powerful therapeutic modality converts malignancy to clinically manageable disease. However, the T cell- and chimeric antigen receptor T (CAR-T) cell-mediated antimetastatic activity, especially their impacts on microscopic metastatic lesions, has not yet been investigated. Here we report a living zebrafish model that allows us to visualize the metastatic cancer cell killing effect by tumor- infiltrating lymphocytes (TILs) and CAR-T cells in vivo at the single-cell level. In a freshly isolated primary human melanoma, specific TILs effectively eliminated metastatic cancer cells in the living body. This potent metastasis-eradicating effect was validated using a human lymphoma model with CAR-T cells. Furthermore, cancer-associated fibroblasts protected metastatic cancer cells from T cell-mediated killing. Our data provide an in vivo platform to validate antimetastatic effects by human T cell-mediated immunotherapy. This unique technology may serve as a precision medicine platform for assessing anticancer effects of cellular immunotherapy in vivo before administration to human cancer patients.

- Multiple sclerosis (MS) is a neuro-inflammatory and neurodegenerative disease that results in damage to myelin sheaths and axons in the central nervous system and which preferentially affects young adults. We performed a proteomics-based biomarker discovery study in which cerebrospinal fluid (CSF) from MS and control individuals was analyzed (n=112). Ten candidate biomarkers were selected for evaluation by quantitative immunoassay using an independent cohort of MS and control subjects (n=209). In relapsing remitting MS (ARMS) patients there were significant increases in the CSF levels of alpha-1 antichymotrypsin (A1AC), alpha-1 macroglobulin (A2MG) and fibulin 1 as compared to control subjects. In secondary progressive MS (SPMS) four additional proteins (contactin 1, fetuin A, vitamin D binding protein and angiotensinogen (ANGT)) were increased as compared to control subjects. In particular, ANGT was increased 3-fold in SPMS, indicating a potential as biomarker of disease progression in MS. In PPMS, A1AC and A2MG exhibit significantly higher CSF levels than controls, with a trend of increase for ANGT. Classification models based on the biomarker panel could identify 70% of the RRMS and 80% of the SPMS patients correctly. Further evaluation was conducted in a pilot study of CSF from RRMS patients (n=36), before and after treatment with natalizumab.

- We need high-quality data to assess the determinants for COVID-19 severity in people with MS (PwMS). Several studies have recently emerged but there is great benefit in aligning data collection efforts at a global scale. Objectives: Our mission is to scale-up COVID-19 data collection efforts and provide the MS community with data-driven insights as soon as possible. Methods: Numerous stakeholders were brought together. Small dedicated interdisciplinary task forces were created to speed-up the formulation of the study design and work plan. First step was to agree upon a COVID-19 MS core data set. Second, we worked on providing a user-friendly and rapid pipeline to share COVID-19 data at a global scale. Results: The COVID-19 MS core data set was agreed within 48 hours. To date, 23 data collection partners are involved and the first data imports have been performed successfully. Data processing and analysis is an on-going process. Conclusions: We reached a consensus on a core data set and established data sharing processes with multiple partners to address an urgent need for information to guide clinical practice. First results show that partners are motivated to share data to attain the ultimate joint goal: better understand the effect of COVID-19 in PwMS.
