Early pregnancy reshapes breast aging and lowers cancer risk

A new study by cell biologists at the University of California, Santa Cruz, suggests that an early first pregnancy may protect against breast cancer decades later by preventing age-related changes in breast cells that are linked to tumor formation.

Aging alters social preferences through distinct brain mechanisms

The loss of social connectedness as people age increases the odds of cognitive-related disorders and can worsen health outcomes in older populations. But is there a direct relationship between social behavior and cognition? Subhadeep Dutta Gupta, Peter Rapp, and colleagues, from the National Institute on Aging, developed a rat model to probe social cognition in the aging brain.

New liquid biopsy detects early cancers through epigenetic instability

Researchers at the Johns Hopkins Kimmel Cancer Center have developed a novel liquid biopsy approach to identify early-stage cancers by measuring the random variation in DNA methylation patterns, rather than the absolute level of those patterns as in other liquid biopsies.

Study finds five distinct human sleep chronotypes

The familiar labels "night owl" and "early bird," long used in sleep research, don't fully capture the diversity of human internal clocks, a new study has found.

Mouse study reveals mechanism driving first night insomnia

You check into a hotel and toss and turn all night, but your sleep improves the following night. Scientists at Nagoya University wanted to understand why this happens.

Novel RNA molecule may influence patient survival in certain blood cancers

In a recent study published in the Proceedings of the National Academy of Sciences (PNAS), researchers at the Texas A&M University Health Science Center (Texas A&M Health) identify a novel RNA molecule that plays a crucial role in preserving the integrity of a key cellular structure, nucleolus (a dense region of the cell containing a subset of crucial genetic material).

Researchers uncover a new cellular process linked to healthy aging

Improvements in public health have allowed humankind to survive to older ages than ever before, but, for many people, these added golden years are not spent in good health.

Regulating microglial phagocytosis through immunotherapy could slow Parkinson's disease progression

By analyzing tissue from patients with Parkinson's disease, and animal and cellular models of the disease, a research team from the Institut de Neurociències of the UAB has shown that the main immune cells of the brain become reactive and overexpress certain receptors that promote the elimination of dopaminergic neurons, even when these neurons are still functional.
