Oral health for older adults

Oral health risks for older adults include increased incidence of tooth decay, gum disease, and complete loss of teeth. Practicing good oral hygiene, using fluoride treatments, and getting regular dental care can help prevent these complications.

Coastlines' contribution to climate change might have been underestimated

A new study found that eroding permafrost coastlines in the Arctic can release significant quantities of carbon dioxide, potentially exacerbating climate change. The research simulated erosion effects in a lab experiment and found CO2 was released as rapidly from thawing permafrost in seawater as it is from thawing permafrost on land.

Air pollution in India is associated with higher risk of cardiovascular disease

A new study published in International Journal of Epidemiology found a strong association between air pollution and carotid intima-media thickness (CIMT) in peri-urban South India. People exposed to higher levels of fine particles had a higher CIMT index, indicating a higher risk of cardiovascular diseases.

TTUHSC researchers publish preclinical data on new drug combination to treat neuroblastoma

Researchers at Texas Tech University Health Sciences Center have developed a novel drug combination using fenretinide and venetoclax to treat high-risk neuroblastoma. The study found that the combination of these two drugs showed significant activity against neuroblastoma cells, with multiple complete responses achieved in patients.

Superfood for Mesozoic herbivores? Emerging data on extreme digestibility of equisetum and implications for young, growing herbivorous sauropods

A study by Carole Gee and colleagues confirms equisetum's importance as a digestible and nutritious food source for herbivorous dinosaurs in Mesozoic times. The researchers found that young and growing sauropods, which require rapid growth, would have relied on equisetum as a major food source.

Stanford scientists link Neanderthal extinction to human diseases

Researchers suggest that diseases may have played a crucial role in the extinction of Neanderthals. By employing mathematical models, they demonstrate how unique diseases harbored by Neanderthals and modern humans could have created an invisible disease barrier, ultimately allowing modern humans to supplant their cousins.

Heart attack modeled with human stem cells

Scientists at Okayama University created a human stem cell-based model of myocardial infarction, allowing for the evaluation of tissue damage and inflammation. This new model offers a more accurate representation of human heart conditions, enabling the development of more effective preventive and therapeutic medicines.
