In a US study published in Science, researchers detected immune memory to SARS-CoV-2 across all immune cell types studied for as long as 8 months after patients became ill with COVID-19.

A new study suggests a link between toxoplasma gondii (T. gondii) infection and the risk of glioma, a type of brain cancer, in adults. The report, appearing in the International Journal of Cancer, finds that people who have glioma are more likely to have antibodies to T. gondii (indicating that they have had a previous infection) than a similar group that was cancer free.

Anorexia is a debilitating eating disorder, and was long thought to be purely psychological. New research is challenging this by revealing that gut microbes may have a significant role in anorexia. A recent review examines the evidence that gut microbes can contribute to anorexia and may provide a new method to treat it.

The study was carried out with data from 89 patients admitted to the IFEMA Hospital The data show that telomeres are shorter in patients suffering more severe COVID-19 pathologies The researchers propose that one of the consequences of the viral infection is shortening of the telomeres, which, in turn, hampers the regeneration of lung tissue and causes prolonged sequelae in some patients The study, published in the journal Aging, suggests the usefulness of a possible therapy for patients with post-COVID pulmonary injury based on activation of the enzyme telomerase

All prediabetes is not the same: in people in the preliminary stages of type 2 diabetes, there are six clearly distinguishable subtypes, which differ in the development of the disease, diabetes risk, and the development of secondary diseases. This is shown in a study by the Institute for Diabetes Research and Metabolic Diseases (IDM) of Helmholtz Zentrum München at the University of Tübingen, Tübingen University Hospital and the German Center for Diabetes Research (DZD). The results have now been published in Nature Medicine. The new classification can help in the future to prevent the manifestation of diabetes or the development of diabetes complications through targeted prevention.

Brown fat is that magical tissue that you would want more of. Unlike white fat, which stores calories, brown fat burns energy and scientists hope it may hold the key to new obesity treatments.

Researchers from the Polytechnic University of Valencia (UPV), in collaboration with specialists from the University of Valencia (UV), have come up with a new system based on a high-sensitivity mass biosensor that continuously monitors signals for the direct detection of SARS-CoV-2 in environmental aerosols. The device, in prototype phase, makes it possible to assess the quality of the air and allows an early detection of the virus in inside spaces such as homes, classrooms, restaurants, cinemas or means of transportation.

Investigations of a cellular protein have uncovered a possible link with schizophrenia.
