Teens say they can access firearms at home, even when parents lock them up, new research shows

Among the billions of neurons in the brain, fewer than 500 are responsible for suppressing binge drinking, according to new research by Gilles E. Martin, Ph.D., associate professor of neurobiology.

The COVID-19 pandemic caused by SARS-CoV-2 infection is marked by excessive inflammation of several organs, leading to multi-organ failure. The recognition of the virus by our bodies triggers severe immune responses, causing a "cytokine storm," which can lead to acute lung injury and acute respiratory distress syndrome.

There are many factors that contribute to infant language development, not least of which is baby talk—the modified speech mothers and other adults often use when speaking to infants.

A new study in Neurodegenerative Diseases looks closely at how Parkinson's disease can affect something as everyday and essential as recognizing emotion in someone's voice. The research suggests that both the side of the body most affected by symptoms and the medications used to treat those symptoms may influence how patients interpret vocal emotion.

The U.S. Food and Drug Administration has approved the Sonu Band, an artificial intelligence-enabled, wearable medical device for at-home treatment of moderate-to-severe nasal congestion in pediatric patients aged 12 and up.

Hepatic stellate cells (HSCs) are activated to heal the liver when it has a lesion (such as fibrosis or fatty liver); their function is to protect the liver by producing an extracellular matrix comprising collagen, among other things, and creating a scar in the damaged liver. But the Cancer and Translational Medicine research group of the University of the Basque Country (EHU) found that these stellate liver cells help the metastatic tumor develop.

Researchers have developed a novel method for simultaneously recording action potentials (APs)—temporary changes in electrical potential when cells become excited—and calcium transients—calcium fluctuations that drive muscle contraction—in single cardiomyocytes (heart muscle cells) derived from iPS cells.

T-follicular helper (TFH) lymphoma is a blood cancer subgroup that continues to demonstrate a generally poor prognosis, with no standard treatment established to date. Although specific genetic mutations are frequently observed in this disease, the association between genomic abnormalities and clinical features and prognosis remains unclear.

A senior US health official on Tuesday admitted President Donald Trump's administration had gone too far in slashing biomedical research grants worth billions of dollars, and said efforts were underway to restore some of the funding.

Ice baths are everywhere in modern fitness culture. From professional athletes to weekend warriors, many swear by the post-workout plunge, hoping the icy shock will ease soreness, calm inflammation and help their bodies bounce back faster. But recent research from the Netherlands reveals a surprising downside: Those freezing dips might actually slow muscle growth.

A study in Nature Communications reveals, for the first time, how the transcriptomic profile of human tuberculosis lung lesions is correlated with clinical data from the same patients.

CAR-T cells are specialized immune cells genetically modified to recognize and attack cancer cells. Researchers at Nagoya University in Japan and their collaborators have developed new CAR-T cells to target malignant tumors. While similar treatments have worked well for blood cancers, treating solid tumors is more difficult. Their method, published in the Journal for ImmunoTherapy of Cancer, targeted a protein found in high amounts on many types of cancer cells (Eva1), and successfully eliminated tumors in lab mice.

Microglia are a specialized type of immune cell that accounts for about 10% of all cells within the brain and spinal cord. They function by eliminating infectious microbes, dead cells, and aggregated proteins, as well as soluble antigens that may endanger the brain and, during development, also help shape neural circuits enabling specific brain functions.

A person's level of social and economic status can shape their brain heath in later life, a study suggests. Research led by the University of Edinburgh found a connection between socioeconomic status and changes in the white matter of the brain—a known risk factor of cognitive decline and dementia in older age.

Deep within our nerve cells, a molecule is at work that has no beginning and no end. Instead of a straight chain, as is common for most RNA strands, it forms a closed loop. Known as circular RNAs (circRNAs), these molecules are crucial for development, thought, and synaptic function, yet their high prevalence in neurons has long been a scientific mystery. How does the brain produce so many of them?

Heating the lower limbs before exercise has been found to significantly improve endurance in individuals with heart failure.

A new study to be presented at the SLEEP 2025 annual meeting found that teens who get moderate—but not excessive—catch-up sleep on weekends have fewer symptoms of anxiety.

A new study conducted by researchers at the Hebrew University of Jerusalem reveals how seemingly irrelevant visual cues—known as peripheral information—can significantly influence emotional responses, especially among individuals with depressive symptoms.
