COVID-19 may trigger hyperglycemia and worsen disease by harming fat cells

COVID-19 may bring high risks of severe disease and death in many patients by disrupting key metabolic signals and thereby triggering hyperglycemia, according to a new study from researchers at Weill Cornell Medicine and NewYork-Presbyterian.  In the study, reported Sept. 15 in Cell Metabolism, the researchers found that hyperglycemia—having high blood sugar levels—is common in hospitalized COVID-19 patients and is strongly associated with worse outcomes. The researchers also found evidence suggesting that SARS-CoV-2, the coronavirus that…

Why odors trigger powerful memories

Odors evoke powerful memories, an experience enshrined in literature by Marcel Proust and his beloved madeleine. A new Northwestern Medicine paper is the first to identify a neural basis for how the brain enables odors to so powerfully elicit those memories. The paper shows unique connectivity between the hippocampus—the seat…

VAV1 gene mutations trigger T-cell tumors in mice

Life is an exquisite orchestration of growth and change, with checks and balances that fine-tune complex entwined interactions, both intrinsic and external. White blood cells (WBC) are integral to an organism’s immune defenses against disease and invasion; unfortunately, these mechanisms may go awry causing uncontrolled increases in dysfunctional cell numbers,…
