    Multiple sclerosis (MS) is a chronic autoimmune disorder that attacks the central nervous system. For years, Epstein-Barr virus (EBV) has been strongly linked to MS, as nearly every person diagnosed with the condition shows evidence of past EBV infection. For example, a 2022 study analyzed millions of U.S. military recruits and found that getting infected with EBV increased a person’s risk of developing MS 32-fold.

    But exactly how EBV is linked to the abnormal immune response seen in MS has remained unclear until now.

    In a study published in Science Translational Medicine, scientists descr...

    Left-hand image:  Light sheet fluorescence microscope images of mouse brain 12h after NOT being treated with nanoparticles. The brains were analyzed to see the amount of Aβ plaques accumulation. Red: Aβ plaques. Green: vessels from the blood brain barrier. Right-hand image: Light sheet fluorescence microscope image of mouse brain 12h after being treated with nanoparticles.

    A research team co-led by the Institute for Bioengineering of Catalonia (IBEC) and West China Hospital Sichuan University (WCHSU), working with partners in the UK, has demonstrated a nanotechnology strategy that reverses Alzheimer’s disease in mice.

    Gas stoves emit nanocluster aerosol that may get deep into your respiratory system, study shows. Cooking on your gas stove can emit more nano-sized particles into the air than vehicles that run on gas or diesel, possibly increasing your risk of developing asthma or other respiratory illnesses, a new Purdue University study has found.

    Combustion remains a source of air pollution across the world, both indoors and outdoors...

    Thermal MagIC: Digging into the Details of an Ambitious New ‘Thermometry Camera’

    Left: Diagram of the series of tiny wells, in clusters of fours, filled with solution. Each well in a foursome is spaced away from the other wells by a certain amount, anywhere from 0.1 mm (very close together) to 1 mm (further apart). Right: The magnetic particle image itself, showing distinctions between the wells spaced farther apart but not between the wells spaced close together. The dashed red circle in both images shows the foursome of wells spaced 0.5 mm apart.

    Thermometers can do a lot of things: Measure the temperature at the center of your perfectly braised chicken or tell you whether to keep your child home from school due to illness. But because of their size, traditional thermometers’ uses are still limited.

    “How do you non-invasively measure a temperature...
