A research group has developed a new COVID-19 testing system using Janus particles—microparticles with two sides possessing distinctive molecular properties. These particles are engineered to bind specifically to target antigens, such as viral proteins, creating a low-cost, accurate, and rapid means of testing for viral diseases. The system’s versatility means it can potentially be used to test for other diseases and biomarkers linked to other conditions.

Researchers from Osaka University found that T cells recognize neoself-antigens––abnormal, unfolded host proteins presented by major histocompatibility complex II (MHC-II) lacking the invariant chain––as non-self antigens, leading to the development of autoimmunity. Reactivation of Epstein–Barr virus, a known risk factor for lupus onset and exacerbation, increases the presentation of neoself-antigens by MHC-II, which could help explain the link between viral infection and autoimmune disease.

The oxygen evolution reaction (OER) is an electrochemical process in which water or hydroxide ions are oxidized to produce oxygen gas, playing a crucial role in water splitting and energy conversion. The OER requires efficient catalysts, and now a research group has enhanced the efficiency of traditional cobalt oxide catalysts by doping them with erbium.

A better understanding of how cells regulate their membranes could lead to new treatments for diseases such as epilepsy and anemia.
