Science & Health Summary

Researchers in Greenland have discovered that massive hidden waves are rapidly melting the glaciers, using a 10-kilometer fiber-optic cable to monitor how iceberg calving disturbs warm seawater. These resulting surface tsunamis and underwater waves contribute significantly to the melting process, highlighting the urgency of understanding climate change impacts in polar regions.

Meanwhile, a significant study has shown that self-hypnosis can reduce menopausal hot flashes by half, surpassing the effectiveness of an active placebo. This six-week at-home program not only alleviated symptoms but also improved women's daily functioning and sense of control, offering a promising alternative for those seeking relief without hormone therapy.

In another health-related development, parents in North Carolina have temporarily halted Medicaid cuts that they argue jeopardized their children's progress, showcasing the ongoing struggle for healthcare access amid legislative changes.

On a global scale, health experts are warning of a surge in yellow fever and dengue cases in South America, exacerbated by rising global temperatures. The climate crisis continues to worsen disease outbreaks, leading to increased health risks for vulnerable populations.

Additionally, experts are expressing concern over conflicting advice regarding COVID-19 vaccinations. With only about one in four American adults receiving a vaccine during the latest season, many fear that varying recommendations could further reduce already low vaccination rates, undermining public health efforts.

Lastly, a systematic review from the University of Pennsylvania indicates that general anesthesia may be a safe alternative for C-sections, countering longstanding concerns about its potential harm to newborns.

This new evidence offers healthcare providers more options when spinal or epidural anesthesia fails, ultimately enhancing patient care during childbirth.
