Average age of young fatal stab victims now 14, national data indicate

In an analysis of child and teen fatalities from 2019 to 2024, the average age of young fatal stab victims is now 14, with Black ethnicity individuals being 13 times more likely to be fatally stabbed. Children living in the most deprived areas are 7 times more likely to die of their wounds than those in affluent areas.

Study uncovers hidden factor shaping dementia caregiving stress

A study from Rice University reveals that caregivers' relationships play a crucial role in their mental and physical health. Caregivers who are more self-reliant or emotionally distant experience worse health outcomes, but those with higher relationship satisfaction have stronger buffering effects.

Novel strategies for coral restoration

Researchers at University of Miami developed a novel strategy to enhance survival rates of lab-grown baby corals by modifying the alkalinity of growth tiles. By increasing sodium carbonate levels, they observed a fourfold improvement in early-stage coral survival, paving the way for potential coral restoration efforts.

Mini brain-like structures grown in lab may help scientists treat, diagnose and stage Alzheimer’s disease

Researchers from Johns Hopkins Medicine have developed mini brain-like structures grown in the lab that could be used to evaluate how patients with Alzheimer's disease respond to certain drugs. The study found that tiny particles secreted by these brain tissues may contain cellular information that could help scientists find new biomar...

Are your staffing metrics enough? New research on patient falls says maybe not

A new study from the University of Pennsylvania School of Nursing's Center for Health Outcomes and Policy Research found that nurses' assessments of their staffing adequacy is a more accurate predictor of patient safety on medical surgical units than traditional administrative data. In contrast, objective metrics like RNHPPD proved to ...

Fondazione Telethon’S Genomic Program end the diagnostic odissey for hundreds of children

The program achieved a definitive genetic diagnosis in nearly half of enrolled children, identifying pathogenic variants across 330 genes. Families received timely diagnoses, allowing accurate genetic counseling and informed reproductive choices, while guiding clinical management and opening access to targeted therapies.

Massive Atlantic sargassum blooms traced to west Africa

Scientists have traced the origin of massive Atlantic Sargassum blooms to coastal waters near the Gulf of Guinea in West Africa. The study uses physics-based modeling and probabilistic analysis to show that blooms can be tracked back up to two years before they are detected by satellites.

Implanted nerve stimulation for obstructive sleep apnea found to be safe and effective in new trial

A new trial found that proximal hypoglossal nerve stimulation (pHGNS) significantly reduced breathing interruptions during sleep and improved daytime sleepiness without adverse events. The therapy, an FDA-approved alternative to nasal positive airway pressure, was found to be safe and effective in patients with moderate-to-severe obstr...

The physics of brain development: How cells pull together to form the neural tube

Georgia Tech researchers used computer models to reveal how cells physically pull the neural tube closed during early development. The study found that forces generated by cells create a 'purse string' mechanism made of actin, which tightens and draws the tube closed through a synchronized pattern of cell movement.

Exercise and cancer research: Ibuprofen is another option to ease chemo-brain

A new study suggests that a low dose of ibuprofen can help alleviate chemo-brain symptoms in cancer patients, but exercise remains the most beneficial intervention. Researchers randomized 86 patients to receive either exercise plus ibuprofen or other treatments and found that exercise significantly improved cognitive function.

Study finds each protein in the epigenome produces a different pattern of gene expression

A new study found that every type of epigenome protein produces a distinct pattern of gene expression, surpassing the on/off switch functionality. This discovery has significant implications for cellular engineering, enabling more dynamic control over cellular behavior and potential applications in biomanufacturing and bioproduction.

Research links tinnitus with serotonin

A new study published in the Proceedings of the National Academy of Sciences found a link between elevated serotonin levels and tinnitus behavioral symptoms. The research suggests that clinicians should recognize and validate patient reports of medication-associated increases in tinnitus when prescribing antidepressants like SSRIs.

Lost millennium of Galápagos deep-sea corals linked to major Pacific climate shift

Scientists discovered that deep-water coral ecosystems in the Galápagos region vanished for over 1,000 years due to prolonged La Niña-like conditions. The study found that these ecosystems may be more susceptible to climate change than previously thought, with significant implications for conservation efforts.

A CNIO group contributes to identifying which breast lesions will progress to cancer, thus helping avoid overtreatment

A study by the CNIO group has identified a genetic signature in precancerous breast lesions that can predict which ones will evolve into invasive tumours. This discovery could help avoid over-treatment of women diagnosed with ductal carcinoma in situ, a common precancerous lesion.

Earliest Cambrian microfossils preserve ringed worms

The discovery of seven millimeter-sized phosphatized fossils from the early Fortunian Kuanchuanpu Formation provides evidence of annelid body fossils from Cambrian Orsten-type fossil localities. The findings suggest that early annelids were polychaetes, supporting the hypothesis that polychaete morphologies were primitive among annelids.
