Rare aging disorder links 'biological clock' to disease

Scientists have discovered a rare genetic condition that causes people to age at a much faster rate, offering fresh insights into the aging process. The study shows for the first time how a "biological clock" present in every cell of the body could contribute to age-related disea

Cancer also knows how to wait: Study uncovers the hidden step between mutation and tumor b

The development of cancer is not a process triggered immediately by the emergence of an oncogenic mutation. There is growing evidence for the existence of an intermediate phase—hitherto poorly defined—in which mutated cells remain in a latent state, "accumulating the potential ne

Tumors hijack macrophages after they clear dead cells, real-time tracking reveals

Researchers at Tel Aviv University's Gray Faculty of Medical and Health Sciences have uncovered how a natural and essential immune system process can be hijacked to promote cancer progression. In a new study, the research team developed an advanced technology that enabled it to t

Human red blood cells form without central 'hub' seen in mouse models, upending understand

Northwestern Medicine scientists have discovered that one of the body's most fundamental biological processes—how red blood cells are made—works differently in humans than previously thought, according to a new study published in Nature Genetics. The findings overturn decades of

Forcing cancer cells to die can alert the immune system to enhance anti-tumor attack

Unlike accidental cell death, some cells can actively decide to die through a controlled process. This is called programmed cell death and can occur in different forms, including apoptosis and necroptosis. Cells use this process when they are damaged, stressed, becoming cancerous

The 'healthier' drink that isn't: Popular alcoholic beverages found to be ultra-processed

Canned cocktails and hard seltzers are being chosen by health-conscious young people as a safer way to consume alcohol, but new Australian research reveals these products are almost universally ultra-processed, potentially giving consumers a false sense of security and underminin

Scientists uncover two neuronal circuits orchestrating muscle autophagy

Autophagy is the process by which cells remove damaged proteins, recycle worn-out organelles (e.g., mitochondria), clear cellular waste and provide nutrients during stress. Autophagy is essential for muscles because they are constantly under mechanical stress. If autophagy is too

Ultra-processed foods linked to higher levels of 'bad' fatty acids in blood, study suggest

Consumption of ultra-processed food (UPF) results in a distinct metabolic "signature" in the blood, associated with potentially adverse health conditions, suggests a new study by an international team of researchers. The paper, published in Critical Reviews in Food Science and Nu

Neuroscientists observe electrical signals in the soma and dendrites of living mice

The human brain contains billions of neurons, specialized nerve cells that communicate with each other via electrical and chemical signals. Every neuron is made up of its body (i.e., soma), where most cellular processes occur; a long projection called an axon that sends signals t
