Study uncovers how a mobile genetic element hijacks human cells

Viruses are known to use the genetic machinery of the human cells they invade to make copies of themselves. As part of the process, viruses leave behind remnants throughout the genetic material (genomes) of humans.

Lysosomal lipid peroxidation drives ferroptosis in cancer cells

The duplication and division of cells is critical to keeping all multicellular organisms alive. But the opposite process is equally important: cell death.

Study uncovers 'cell of origin' of the second most common lung cancer

The 'cell of origin' of the second most common lung cancer and the way that it becomes dominant in the lung have been discovered, in a new study in mice and humans from researchers at UCL, the Wellcome Sanger Institute and the University of Cambridge.

Gut immune cells linked to worsening rheumatoid arthritis

After spending years tracing the origin and migration pattern of an unusual type of immune cell in mice, researchers have shown in a new study how activity of "good" microbes in the gut is linked to rheumatoid arthritis and, potentially, other autoimmune diseases.

COVID-19 leaves longer-lasting symptoms than flu or pneumonia, study finds

A large U.S. cohort study found that post-acute symptoms after COVID-19 vary by initial disease severity, age, sex, and comorbidities. Compared to influenza and pneumonia, long COVID presented with distinct symptom patterns and longer-lasting effects.

Getting active in midlife may boost brain resilience to Alzheimer’s

In cognitively healthy middle-aged adults at risk for Alzheimer’s disease, becoming physically active, especially in line with WHO guidelines, was linked to lower brain amyloid burden. Remaining sedentary was associated with reduced cortical thickness in brain regions vulnerable to AD.

What predicts belief in the afterlife? A massive global study has answers

A large global study of over 202,000 adults in 22 countries found that belief in an afterlife is shaped not only by religious exposure in childhood, but also by early emotional and familial experiences. Weekly religious attendance at age 12 was the strongest and most consistent predictor of adult afterlife belief.

Retinal exams show promise for early detection of Parkinson's disease

Could it be possible to diagnose Parkinson's disease with the help of a simple retinal exam? The idea should be seriously considered, according to a study published in the May issue of Neurobiology of Disease by researchers from Université Laval who discovered that the retina of people with Parkinson's disease responds differently to light stimuli than that of healthy people.

Exploring the relationship between mitochondrial quality control mechanisms and atherosclerosis

Announcing a new article publication for Cardiovascular Innovations and Applications journal. Mitochondrial quality control (MQC) mechanisms - including biogenesis, dynamics, mitophagy, proteostasis, the unfolded protein response, and mitochondrial-derived vesicles - play critical roles in the development of atherosclerosis.

Caffeine increases brain complexity during sleep and shifts it toward a critical state

Caffeine shifts brain activity during sleep by increasing EEG complexity and reducing long-range temporal correlations, particularly in non-REM (NREM) sleep. These changes reflect a movement toward a “critical regime” of neural processing, more pronounced in younger adults.

Childhood health and family ties boost adult optimism, study finds

A large international study of 203,000 adults across 22 countries found that early-life experiences—such as childhood health, family relationships, and religious upbringing—significantly shape levels of optimism in adulthood. Cultural context also influenced whether factors like parental divorce had negative or positive effects.

How much ultra-processed food is too much? This study has the answer

A meta-analysis across eight countries found that every 10% increase in ultra-processed food (UPF) intake was linked to a 2.7% rise in all-cause mortality. The study estimates up to 124,000 premature deaths annually in the U.S. alone may be attributable to high UPF consumption.
