Stopping anti-obesity medications leads to significant weight regain, starting as early as eight weeks and stabilizing by six months. Despite this rebound, most patients maintain some weight loss compared to baseline a year after discontinuation.

The COVID-19 pandemic accelerated biological brain aging in older adults by an average of 5.5 months over less than three years, regardless of infection status. Social disruption, age, male sex, and socioeconomic disadvantage heightened vulnerability, while only infected individuals showed measurable declines in executive function.

New research reveals that tiny amounts of PFAS-widely known as "forever chemicals"-cross the placenta and breast milk to alter infants' developing immune systems, potentially leaving lasting imprints on their ability to fight disease.

In a breakthrough that reimagines the way the gut and brain communicate, researchers have uncovered what they call a "neurobiotic sense," a newly identified system that lets the brain respond in real time to signals from microbes living in our gut.

Why do so many people relapse after quitting cocaine? A new study from The Hebrew University reveals that a specific "anti-reward" brain circuit becomes hyperactive during withdrawal-driving discomfort and pushing users back toward the drug.

Adolescents who use either e-cigarettes or conventional tobacco products (CTP)-like cigarettes, cigars, hookah and pipes-are significantly more likely to report symptoms of depression and anxiety than teens who don't use tobacco products at all, according to a study published this week in the open-access journal PLOS Mental Health by Noor Abdulhay of West Virginia University, USA, and colleagues.

Researchers at the Francis Crick Institute have mapped the human metabolic pathways that Cryptosporidium, an intestinal parasite, requires to survive.

Researchers have identified a key neural switch that controls whether animals instinctively flee from a threat or freeze in place.

Mosquitoes kill more people each year than any other animal. In 2023, the blood-sucking insects infected a reported 263 million people with malaria, leading to nearly 600,000 deaths, 80% of which were children.

While current treatments for schizophrenia - a mental illness affecting 1% of the world's population - can reduce certain symptoms, they have little effect on the cognitive deficits affecting the daily life of patients.

In a new study, Northwestern University neurobiologists found the brain's internal GPS changes each time we navigate a familiar, static environment.

Nearly one in four teenagers are using dating apps - and it may not be hurting their mental health, suggests a new Northwestern Medicine study that monitored adolescents over six months.

A review published in Advanced Science highlights the evolution of research related to implantable brain-computer interfaces (iBCIs), which decode brain signals that are then translated into commands for external devices to potentially benefit individuals with impairments such as loss of limb function or speech.

Americans who drink heavily are more than twice as likely to develop significant liver disease compared to 20 years ago, according to a new Keck Medicine of USC study published today in Clinical Gastroenterology and Hepatology.

A $1.1 million grant from the parent-caregiver-led Rare Bird Foundation to Weill Cornell Medicine is supporting the launch of a natural history study for a rare neurodevelopmental disorder that causes developmental delays and seizures called MEF2C Haploinsufficiency syndrome (MCHS).

Announcing a new article publication for Zoonoses journal. This study was aimed at analyzing the pathogenic characteristics of Bordetella hinzii (B. hinzii), and elucidating its antibiotic resistance mechanisms, virulence gene distribution, and vaccine development potential.

Elenagen™, a novel DNA plasmid therapy that previously demonstrated high clinical benefit and low toxicity in cancer patients, has now shown significant promise in alleviating chronic pain demonstrating a 90% success rate.

The blood pressure lowering effect of nitrate-rich beetroot juice in older people may be due to specific changes in their oral microbiome, according to the largest study of its kind.

A groundbreaking brain imaging study from Wake Forest University School of Medicine confirms a vital step toward new Alzheimer's disease treatments: Intranasal insulin, delivered via a simple nasal spray, safely and effectively reaches key memory regions of the brain in older adults.

Researchers developed a diagnostic test based on the LIMA1-alpha protein to distinguish patients with head and neck squamous cell carcinoma who can be cured with surgery alone, without the need for radiation or chemotherapy.
