Research Shows Dangerous, Growing Trend of Illicit Fentanyl Use
Law enforcement seizures of pills containing illicit fentanyl increased dramatically since 2018, according to a new NIDA-funded study published in Drug and Alcohol Dependence.
Mandatory Masking Reduced Covid-19 Cases in Schools During Delta
Schools with mandatory masking during the Delta surge had approximately 72 percent fewer cases of in-school transmission of SARS-CoV-2 compared with schools with optional or partial masking policies, according to an NIH-funded study
NIH Launches Trials of Three HIV mRNA Vaccines
NIAID has launched a phase 1 clinical trial evaluating three experimental HIV vaccines based on a messenger RNA (mRNA) platform—a technology used in several approved Covid-19 vaccines.
Can Restricting Calories Extend Your Life?
Calorie restriction—reducing food intake without causing malnutrition—can yield health benefits that include improved metabolism and delayed onset of age-associated diseases.
Scientists Discover New Molecular Pathway Shared by Two Neurodegenerative Disorders
Scientists from two independent research teams have discovered how the mislocalization of a protein, known as TDP-43, alters the genetic instructions for UNC13A, providing a possible therapeutic target that could have implications in treating amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD) and other forms of dementia.
Scientists Pinpoint Mechanisms Associated with Severe Covid-19 Blood Clotting
After studying blood samples from 244 patients hospitalized for Covid-19, a group of researchers, including NIH investigators, identified “rogue antibodies” that correlate with severe illness and may help explain mechanisms associated with severe blood clotting.
Researchers Identify Brain Regions Involved in Conversation
A recent NIDCD study mapped the brain during speech planning. The findings may lead to a better understanding of speech disorders such as stuttering.
Advances in Personalized Immunotherapy Hold Promise for Multiple Cancers
NIH researchers have found unique expression profiles in 50 genes that help identify rare anti-tumor lymphocytes that can infiltrate and help defeat metastatic solid epithelial tumors.
Researchers Document Third Case of HIV Remission Involving Stem Cell Transplant
A woman with HIV who received a cord blood stem cell transplant to treat acute myeloid leukemia has had no detectable levels of HIV for 14 months despite cessation of antiretroviral therapy (ART). The woman is the third known case of HIV remission following a stem cell transplant.
