Locating mould and damp in buildings is difficult, sometimes even impossible. The Tekes Fine technology programme explores ways to use the concentration and size distribution of particles to pinpoint mould damage and determine its effect on health. Researchers are also developimg a DNA-based microchip, which can be used for determining the microbes in indoor air rapidly. This is the first experiment where existing medical technologies are being applied to indoor air specimens.
"Up to now, nobody has studied how the concentration and size distribution of particles in the air inside buildings with mould problems differ from those inside healthy buildings. We took measurements in a building with mould problems at all four seasons of the year and measured the effects of repairs on indoor air quality in two buildings", explains Dr. Aino Nevalainen from the National Public Health Institute, who has been leading the research.
"Measurements were also taken in healthy buildings for comparison. The air in the building with mould problems showed inexplicable peaks in particle concentrations that could be caused by damp and mould. Analysis is continuing in those areas."

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.
When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...
Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur
What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...
