Researchers have identified a novel mechanism by which periodontal disease may cause metabolic syndrome. By studying patients with metabolic syndrome, the researchers demonstrated high antibody titers against Porphyromonas gingivalis, the bacterium causing periodontal disease. In a mouse model, the researchers then showed that infection with this bacterium causes systemic insulin resistance and metabolic dysfunction in skeletal muscle by altering the gut microbiome. This study shows the effect periodontal disease can have on the entire body.

Contrary to previous assumptions, visual short-term memory is not merely based on one kind of information about an object, such as only its colour or only its name. Rather, several types of information can be retained simultaneously in short-term memory. Using complex EEG analyses and deep neural networks, researchers have discovered that short-term memory is more complex than previously assumed.

A repair system in our cells fixes DNA damage caused by exposure to ultraviolet (UV) light from the sun, however the detailed process behind this is not fully understood. An international research team has clarified the regulatory mechanism of the ubiquitin-proteasome system in recognizing and repairing UV-damaged DNA. This new discovery will contribute towards illuminating the onset mechanisms of diseases such as skin cancer.

The risk of developing serious complications following a knee replacement could be up to 73% higher when a tourniquet is used, compared to surgery without a tourniquet. Serious complications during knee replacement surgery are rare. However, researchers found that 5.9% of patients whose operations involved a tourniquet had serious complications needing additional health care, compared to 2.9% in those operated on without a tourniquet.
