Scientists uncover why genome guardian p53 protein is uniquely prone to collapse

The protein p53 is often called the guardian of the genome for its central role in preventing cancer. Yet paradoxically, it is also one of the most frequently mutated and dysfunctional proteins in human tumors.

Women may face greater cognitive impact from dementia risk factors

Researchers from the University of California San Diego School of Medicine found that women not only experience a higher burden of certain modifiable dementia risk factors, but also appear more vulnerable to their effects on cognitive function.

Study reveals cellular mechanisms driving resistance to targeted cancer therapies

Despite impressive innovations in medicine, most advanced-stage cancers still carry a grim prognosis. Developing more effective treatments requires a deeper understanding of the cellular processes that drive the formation and growth of common cancers.

Ensitrelvir cuts household COVID-19 risk when given after exposure

Ensitrelvir, an oral SARS-CoV-2 3C-like protease inhibitor, reduced symptomatic RT-PCR-confirmed COVID-19 among household contacts when given within 72 hours after symptom onset in the infected index patient. In the phase 3 SCORPIO-PEP trial, COVID-19 occurred in 2.9% of ensitrelvir recipients versus 9.0% of placebo recipients, with similar overall adverse-event rates.

Anxiety and depression linked to mirror opposite sides of the brain's emotional center

A longitudinal study tracking children over a period of seven years identified distinct brain-wave patterns emerging from age 9 can forecast a child's vulnerability to anxiety or depression by age 13.

Biomimetic nanocomposite hydrogel promotes tendon healing and tissue regeneration

The new system, termed KGN@PB@CM, combines several advanced elements. Prussian blue (PB) nanozymes act as potent reactive oxygen species (ROS) scavengers, while kartogenin (KGN)-a small molecule that promotes stem cell migration and tenogenic differentiation-is loaded onto the PB core.

Gut-localized drug avoids systemic safety risks while reversing hormonal imbalances in mice

Polycystic ovary syndrome (PCOS) is one of the most common hormonal disorders in women of reproductive age. It can cause irregular periods, infertility, weight gain, insulin resistance, and elevated male hormone levels. Current treatments mainly focus on managing symptoms rather than addressing underlying causes.

UniSC study identifies two distinct psychological belief patterns that predict stealthing intent

Men with a strong sense of entitlement are three times more likely to commit "stealthing" during sex, according to a new University of the Sunshine Coast study.

Adjuvanted and high-dose flu vaccines protect older adults equally well

In a large study of 429,595 adults aged 65 years or older, adjuvanted and high-dose influenza vaccines showed no significant difference in protection against PCR-confirmed influenza. The findings support current recommendations that both enhanced vaccines are reasonable options for older adults, while second-season results may further refine the evidence.

560-610 minutes of exercise a week linked to substantial cardiovascular health benefits

Adults should aim to do between 560 and 610 minutes a week of moderate to vigorous physical activity to achieve a substantial reduction in the risk of heart attacks and stroke, suggest the findings of an observational study published online in the British Journal of Sports Medicine.

Opioid-related infections linked to rising amputation rates across United States

Severe infections linked to opioid use often progress rapidly, particularly when access to timely medical care is limited. This can result in devastating health outcomes, including life-altering amputations.

Why AI tools need clearer guardrails in high-stakes health research

AI-enabled research tools can accelerate health research, but their data-science roots may clash with epidemiological workflows built around prespecified designs, causal reasoning, bias control, and reproducibility. The article argues that researchers should integrate AI cautiously, using clear workflow boundaries, peer review of AI outputs, and sustained human accountability.

Facial micromovements may help doctors measure pain more accurately

Researchers at Rutgers University-New Brunswick are working to measure pain more accurately beyond the single, subjective question patients are often asked: "On a scale of 1 to 10, how bad is your pain?"

How does the brain recognize new faces and places in milliseconds?

This Communications Biology study used intracranial EEG in 22 epilepsy patients to map how the human brain processes new images of faces and places within milliseconds.. It found that visual information flows from the occipital cortex through parallel dorsal and ventral pathways toward frontal and limbic regions, with distinct timing patterns for faces and places.
