Study of identical twins links faster aging to memory decline

A special MRI technique that detects iron levels in different regions of the brain can predict the onset of mild cognitive impairment and cognitive decline in cognitively unimpaired older adults, potentially creating a pathway to earlier interventions, according to a study published in Radiology.

Emphysema detected on baseline low-dose chest CT (LDCT) in the lung cancer screening cohort of more than 9,000 asymptomatic adults was associated with death from all causes, chronic obstructive pulmonary disease (COPD), and cardiovascular disease within a 25-year follow-up period in a new study published in Radiology.

A new Emory University study, led by the Emory ALS Center and the Center for Neurodegenerative Disease at Emory's Goizueta Brain Health Institute, sheds light on why a once-promising experimental medication for amyotrophic lateral sclerosis (ALS) failed to help patients, despite successfully reaching its intended target in the central nervous system (CNS)—the brain and spinal cord.

We all know the benefits of a healthy diet. But new research from the University of South Australia shows that eating nutritious food is about far more than ticking off the five food groups—it can also significantly reduce chronic pain.

Researchers identified almost two dozen previously unknown genetic variants linked to type 2 diabetes by including participants' hormone levels in their analysis. Yan V. Sun of Emory University, U.S., and colleagues report these findings in the open-access journal PLOS Genetics.

Preliminary findings from a new clinical trial show no adverse neurodevelopmental effects after brief inhaled anesthesia and surgery in infants and young children, reports Anesthesiology.

The University of Kentucky Markey Cancer Center's Graham Warren, M.D., Ph.D., and international collaborators have led a groundbreaking study that could change the way lung cancer is diagnosed and treated.

Implementing changes to indoor environments, such as cooler bedrooms at night and increasing the amount of bright light during the day, could significantly improve sleep for people living with dementia, according to a study led by the University of Surrey.

The acquisition of opioid treatment programs by private equity investors is a growing national trend, prompting questions about the potential to expand access to methadone, a medication that can cut the risk for overdose deaths by more than half. Opioid treatment programs are currently the only settings with the legal authority to dispense methadone for the treatment of opioid use disorders.

Yale School of Medicine-led research reports that nerve-associated macrophages help maintain healthy fat over a lifespan and curb age-related inflammation.

New research presented identifies interferon-induced transmembrane protein 3 (IFITM3) as a critical regulator of immunotherapy sensitivity in small cell lung cancer (SCLC), offering a promising new avenue for overcoming resistance to PD-1/PD-L1 checkpoint blockade.

A layer deep in the cerebral cortex, which is the innermost layer of the mammalian brain, has recently been found to play a role in the regulation of brain states associated with wakefulness and attention.

Henagliflozin, a popular drug prescribed for type 2 diabetes, has demonstrated potential anti-aging effects in a recent study published in Cell Reports Medicine.

For every motor skill you've ever learned, whether it's walking or watchmaking, there is a small ensemble of neurons in your brain that makes that movement happen. Our brains trigger these ensembles—what we sometimes call "muscle memories"—to get our bodies cooking, showering, typing, and every other voluntary thing we do.

A new analysis from the PALOMA-2 study shows that subcutaneous administration of amivantamab every four weeks (Q4W), in combination with daily oral lazertinib, yields a high objective response rate in patients with previously untreated EGFR-mutated advanced non-small cell lung cancer (NSCLC).

Unarmed Black civilians are three times more likely to be shot and killed by police officers than unarmed white civilians in the U.S. In tragic cases in recent years, unarmed Black men holding innocuous objects like a wallet, cell phone, or vape pen were killed by police officers because those objects were misidentified as weapons.

Women taking popular weight-loss medications during their reproductive years may be unaware of associated risks to pregnancy and unborn babies, warn Flinders University researchers.

As the COVID-19 pandemic wound down, so did the federal government's funding to states that allowed all Medicaid enrollees to keep their coverage even if they no longer would have been eligible otherwise.
