The melting of polar ice due to climate change will open global shipping routes through the Arctic in summer by mid-century, according to experts. More ships in the remote area means greater pollution impacts on the marine ecosystem. What will these impacts look like? In a first commissioning experiment at MAX IV’s SoftiMAX beamline, Swedish researchers analysed the cloud-forming abilities of particle exhaust from ships using low-sulphate fuels as well as high-sulphate fuels conditioned with wet scrubbers. Their findings indicate the fuel types produce different, but unintended effects on particle emissions and therefore, our atmosphere.
Bacterial biomass conversion for renewable fuels
Imagine this future. Vehicles and machinery primarily powered by renewable organic matter, a resource far better for the planet’s health than today’s predominate fossil fuels. What factors stand in the way for a global power transition to competitive, industrial-scale biomass conversion? A study in Nature Communications reveals one key piece of the puzzle using bacterial enzymes. At MAX IV’s BioMAX beamline, an international team of scientists has determined important rate-limiting steps of lignocellulose breakdown, a major hurdle in efficient biomass processing. The discovery holds promise for a significant reduction in manufacturing costs and faster adoption of new biomass-derived fuels to market.
Fragment-based research on potent, non-covalent inflammatory drugs goes forward
Researchers’ collaborative efforts from Denmark and Germany used BioMAX beamline to discover selective, non-covalent inhibitors of Keap1– a common target against oxidative stress and inflammation. The result is a potent antithesis of the currently available drugs acting as covalent inhibitors.
New potential drug for type 2 diabetes treatment explored at MAX IV
The drug discovery company Implexion Pharma and researchers from Lund University have explored new potential drug candidates for type 2 diabetes using X-ray crystallography research techniques at MAX IV.
A toothy temporal map of Arctic climate change
In the vast, remoteness of the Arctic, few have the opportunity to gather data on the environmental conditions over time or decipher the long-term effects of climate change. What is required? A considerable period to observe, a nearly autonomous method or actor for collection, a robust character to withstand the harsh surroundings. Researchers from Aarhus University in Denmark are tackling this issue through an interdisciplinary NordForsk project. At DanMAX beamline, the group will analyse a narwhal tusk to determine its chemical composition and biomineralization, both important potential markers of the changing environment.
Mapping the genetic tools of fungi for fuel production
Fungal enzymes play an important role in the breakdown of plant cell walls during plant degradation. An international collaboration of researchers explored the auxiliary activities 7 (AA7) enzyme family, characterizing four fungal enzymes and uncovering a novel class of flavo-enzymes, exemplified by oligosaccharide dehydrogenase. The enzymes fuel the activity of lytic polysaccharide monooxygenases (LPMOs) in the challenging process of crystalline cellulose degradation. The study, published in Nature Communications, offers promise for tuning the efficiency of enzymatic breakdown processes of biomass feedstocks used in energy and biomaterial production.
Tackling SARS CoV-2 viral genome replication machinery using X-rays
An international collaboration between the UCL School of Pharmacy, the Lund Protein Production Platform (LP3) and ESS, through its DEMAX platform, have performed biophysical and structural studies of three non-structural proteins from the novel coronavirus, SARS CoV-2, the causative agent of COVID-19. In the spring of 2020, they managed to solve and started to analyse one of these proteins, Nsp10, by using the BioMAX beamline at MAX IV Laboratory. Early October published their results in the International Journal of Molecular Sciences.
Clues to block replication of SARS-CoV-2 found with FragMAX platform
An international collaboration of scientists identified four fragments that interact with the nsp10 protein of the SARS-CoV-2 virus using the FragMAX platform and BioMAX beamline. The fragments could be used to develop inhibitors that supplant key enzymes activated by the protein—an application which holds potential to block the viral replication process.
Riverine iron survives salty exit to sea
Iron organic complexes in Sweden’s boreal rivers significantly contribute to increased iron concentration in open marine waters, X-ray spectroscopy data shows. A Lund University study in Biogeosciences characterizes the role of salinity for iron-loading in estuarine zones, a factor which underpins intensifying seasonal algal blooms in the Baltic Sea.
New Eyes on Forest-Based Materials – ForMAX comes online
ForMAX is the 15th beamline to come online at MAX IV. A large part of the research to be conducted at the beamline will promote the development of new materials and speciality chemicals from renewable forest resources. ForMAX is funded by the Knut and Alice Wallenberg Foundation and industrial partners through the Treesearch consortium.
