UC research illuminates 'touchy' subject

Researchers at the University of Cincinnati have solved a century-long puzzle by proving that Merkel cells are the initial sites for sensing touch. Their study published in Cell journal shows that gentle touch triggers action potentials in Merkel cells, mediated by the Piezo2 receptor/ion channel.

New tool advances investigations of disease outbreaks

A new computational tool in Molecular Biology and Evolution helps public health officials investigate disease outbreaks by analyzing genomic data, correctly inferring source cases and transmission clusters. The tool complements traditional epidemiology methods, providing valuable insights into outbreak dynamics.

Breaking bad mitochondria

Hepatitis C virus infects liver cells' energy centers, damaging mitochondria and recruiting proteins to eliminate damaged area. This process helps the virus persist in the body, making mitochondrial operations a potential therapeutic target.

Study: SSRI use during pregnancy associated with autism and developmental delays in boys

A study of nearly 1,000 mother-child pairs found prenatal SSRI exposure was nearly 3 times as likely in boys with ASD relative to typical development. Exposure during the first trimester increased risk for autism spectrum disorder (ASD), while third trimester exposure elevated risk for developmental delays (DD) in boys.

Targeting cancer with a triple threat

Researchers have created nanoparticles that can deliver three or more different chemotherapy drugs to cancer cells, offering new hope for more effective treatments. The particles are designed to release the drugs in response to specific triggering mechanisms, reducing side effects and increasing efficacy.

Groundbreaking nationwide study finds that people of color live in neighborhoods with more air pollution than whites

A groundbreaking nationwide study found that people of color are exposed to 38% higher levels of nitrogen dioxide outdoor air pollution compared to white people. The health impacts are substantial, with an estimated 7,000 deaths from heart disease among nonwhites each year if they breathed the lower NO2 levels experienced by whites.

In child custody disputes, LGBT parents face bias in the courts, new Drexel review finds

A new review from Drexel University finds that court decisions favoring heterosexual parents over gay or lesbian parents often ignore important social science research on parenting by gay and lesbian individuals. The researchers recommend considering this research to guide policy and inform judges' decisions in complex custody cases.
