Astrocytes found to drive brain rewiring during attention states

Researchers at Washington University School of Medicine in St. Louis have upended decades-old dogma of how connections between brain cells are rearranged during states of heightened vigilance or attention.

Lower fitness before infection raises risk of long COVID, study finds

Adults who later developed long COVID had lower cardiorespiratory fitness (CRF) before infection than those who did not. COVID-19 was not linked to accelerated or clinically significant declines in CRF, even among long COVID cases.

Targeting brain neurons to successfully treat type 2 diabetes

Successfully treating type 2 diabetes may involve focusing on brain neurons, rather than simply concentrating on obesity or insulin resistance, according to a study published today in the Journal of Clinical Investigation.

New gene editor evoCAST enables precise insertion of complete genes

Ask scientists what gene editing tool is most needed to advance gene therapy, and they'd probably describe a system that's now close to realization in the labs of Samuel Sternberg at Columbia University Vagelos College of Physicians and Surgeons and David Liu at the Broad Institute of MIT and Harvard.

Harnessing nanomaterials to induce ferroptosis in cancer treatment

Announcing a new publication for Acta Materia Medica journal. Tumor ferroptosis, a regulated form of cell death driven by iron-dependent lipid peroxidation, has emerged as a promising therapeutic strategy for combating cancers, particularly in cases involving cancer stem cells (CSCs) and drug resistance.

Breakthrough bat organoid platform sheds light on behavior of zoonotic viruses

Did you know that more than 75% of new infectious diseases affecting humans originally come from animals? Bats, in particular, are natural hosts to some of the world's most dangerous viruses, including those responsible for COVID-19 (SARS-CoV-2), MERS-CoV, influenza A, and hantavirus outbreaks.

Study links long COVID brain fog to inflammation and stress markers

A new study that is the first to compare inflammation and brain stress responses in long COVID-19 patients with individuals who have fully recovered shows that those with continued brain fog and other cognitive issues have a lower ability to adapt to stress and higher levels of inflammation in their brains.

Scientists reveal how upbringing and genetics interact to shape success

Large-scale registry data from Norway reveal that genetics and shared family environments significantly influence key socioeconomic status indicators, such as education, wealth, income, and occupational prestige. Education shows the strongest genetic influence, while wealth is more affected by family-shared environment. Findings are shaped by both societal context and methodological choices.

New genetic database sheds light on Brazil’s ancestry and disease risks

Since the human genome was first sequenced in 2003, the world's scientific community has been racing to decipher this "book" written in an alphabet of four letters.

Researchers identify key cells behind peanut allergy prevention

A decade ago, a clinical trial in the U.K. famously showed that children who were exposed to peanuts in the early months of life had reduced risk of developing a peanut allergy compared with children who avoided peanuts.

Study finds fewer H. pylori infections among Parkinson’s patients

A large case-control study from China found that people with Parkinson’s disease were significantly less likely to test positive for Helicobacter pylori infection compared to controls. The findings suggest a potential protective link between this common stomach bacterium and Parkinson’s disease, though causality remains unproven.

TMEM219 inhibition shows promise in restoring intestinal health in IBD

An international study led by Paolo Fiorina from Boston Children's Hospital and in collaboration with researchers from University of Milan highlights the beneficial effect of inhibiting the death receptor TMEM219 to restore mucosal healing in inflammatory bowel diseases.
