Across the country, kids are settling into new school year routines. Parents buy backpacks, teachers arrange desks and lesson plans, and friends reconnect.

When public health researchers want to know whether diseases such as COVID-19 or polio are circulating in a community, they can look for genetic evidence in wastewater.

A study initiated by a University of Arizona Cancer Center physician-scientist Dr. Dan Theodorescu revealed that the loss of the Y chromosome in men's body tissue could pave the way for cancer to develop in that tissue.

In the sickest COVID-19 patients, the SARS-CoV-2 virus doesn't just cause severe damage by directly infecting airway cells.

Researchers at The University of Texas MD Anderson Cancer Center have identified a previously unknown role for B cells, which are adaptive immune cells, in triggering and sustaining colitis occurring as a side effect of immune checkpoint inhibitors, a widely used form of cancer immunotherapy.

An irregular pattern and consistently higher levels of a stress hormone called cortisol found in the saliva were associated with cognitive decline later in life - Blacks specifically had lower overall cortisol levels and less change in their levels during the day than whites - according to newly published research.

The Global Virus Network (GVN) is closely monitoring detections of highly pathogenic avian influenza A (H5N1), commonly known as bird flu, in several mammal species in Australia as the virus continues to spread among birds and mammals worldwide.

Why do food cravings become so strong during pregnancy? Researchers at LSU's Pennington Biomedical Research Center, in collaboration with colleagues, have identified a brain mechanism that may help explain how pregnancy changes the motivation to seek certain highly palatable foods.

Researchers have completed the largest study to date of TCF7L2-related neurodevelopmental disorder (TRND), a rare genetic condition caused by changes in the TCF7L2 gene, which plays an important role in brain development.

For centuries, scientists have thought of the brain as a single, unified organ. But new research led by Stanford Medicine reveals that what we call the brain is two distinct organs that evolved independently over hundreds of millions of years.

Sleep problems are common in people with schizophrenia and can worsen quality of life, psychiatric symptoms, cognition, and daily functioning.

There is no cure for HIV. While scientists have made considerable progress in controlling the infection, patients still must take daily antiretroviral medication for the rest of their lives.

New research being presented at the Annual Meeting of The European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28 – Oct 2), suggests that higher levels of moderate-to-vigorous physical activity (MVPA) are associated with a substantially lower risk of developing type 2 diabetes (T2D), particularly among younger adults.

Artificial intelligence (AI) may help identify women and babies at risk of serious health problems earlier in pregnancy, according to a new study analyzing data from more than half a million pregnancies across Sweden, Chile, and Singapore.

Researchers from the National University of Singapore (NUS) have demonstrated an innovative approach for targeted breast cancer therapy using pulsed electromagnetic fields (PEMFs).

Chronic stress from people's everyday lives may be causing lasting structural changes to the heart, harming health and reducing life expectancy.

Dizziness, fatigue, brain fog and a racing heart. They’re commonly associated with Long COVID, but new Adelaide University research suggests that for some people, these symptoms may also be indications of Postural orthostatic tachycardia syndrome (POTS), a debilitating and difficult-to-diagnose condition.

Muscle strain injuries are a common problem in sports, and injuries to the triceps surae, the calf muscle group that includes the gastrocnemius and soleus, can significantly affect athletic performance and return to play.

Women with a higher Body Mass Index in early adulthood may have a lower risk of developing breast cancer after the menopause because of lasting changes in the structure of their breast tissue, according to researchers at The University of Manchester and Manchester University NHS Foundation Trust.

Researchers created xenocortical mice by transplanting human cortical organoids into animals genetically depleted of much of their native cortex, allowing the human tissue to occupy most of the available cortical space and form anatomical connections throughout the host nervous system. The grafts developed diverse cortical cell types, including L5-ET and VEN-like neurons, generated organized neural activity, and produced measurable cellular and behavioral responses to hypoxic injury.
