St. Jude scientists discover how retinoic acid selectively kills metastatic neuroblastoma cells

Neuroblastoma is a solid tumor that occurs in children. When high-risk, the disease has a poor prognosis. Decades ago, adding the drug retinoic acid to neuroblastoma treatment increased survival by 10-15%.

Biomass smoke compounds linked to lung damage and respiratory diseases

Biomass burning-whether from wildfires, wood stoves or agricultural fires-sends massive amounts of tiny particles and chemicals into the air.

PFAS exposure via drinking water contamination may play a role in childhood cancer risk

A study led by the Joe C. Wen School of Population & Public Health at the University of California, Irvine has revealed possible links between exposure to per- and polyfluoroalkyl substances in drinking water and an increased risk of certain childhood cancers.

New tool could revolutionize brain tumor surgery with rapid cancer cell detection

A novel tool for rapidly identifying the genetic "fingerprints" of cancer cells may enable future surgeons to more accurately remove brain tumors while a patient is in the operating room, new research reveals.

Zika virus hijacks tunneling mechanism to infect placental cells

Infection with Zika virus in pregnancy can lead to neurological disorders, fetal abnormalities and fetal death. Until now, how the virus manages to cross the placenta, which nurtures the developing fetus and forms a strong barrier against microbes and chemicals that could harm the fetus, has not been clear.

Younger people more susceptible to nicotine addiction than middle-aged adults

People in their late teens and early 20s may be more sensitive to nicotine and more susceptible to nicotine addiction than middle aged adults, according to a new study in mice from researchers in the Penn State Department of Biobehavioral Health.

Lifestyle and environmental factors play bigger role in health and premature death than genetics

A new study led by researchers from Oxford Population Health has shown that a range of environmental factors, including lifestyle (smoking and physical activity), and living conditions, have a greater impact on health and premature death than our genes.

Vaping and gum health: How does it compare to smoking?

A systematic review found that e-cigarette users show increased plaque and inflammation markers compared to non-smokers, though their gum health fares better than traditional smokers. However, the certainty of these findings is low due to study bias.

Hospital sink drains found to harbor dangerous antibiotic-resistant bacteria

We hope to be cured when we stay in hospital. But too often, we acquire new infections there. Such 'healthcare-associated infections' (HAI) are a growing problem worldwide, taking up an estimated 6% of global hospital budgets.

Nanoscale plastic particles enhance toxin uptake in plants and human cells

Micro- and nanoscale plastic particles in soil and water can significantly increase how much toxic chemicals plants and human intestinal cells absorb, according to two new studies from Rutgers Health that raise fresh concerns about food safety from plastic pollution.

Duke engineers develop synthetic approach to boost bacterial protein synthesis

Biomedical engineers at Duke University have demonstrated a new synthetic approach that turbocharges bacteria into producing more of a specific protein, even proteins that would normally destroy them, such as antibiotics.
