Global Cancer Cases to Rise Sharply by 2050, but Age-Standardized Rate to Decrease

A new report in "The Lancet" projects a significant increase in global cancer cases from 18.5 million in 2023 to 30.5 million in 2050, primarily due to aging populations; however, the age-standardized rate is projected to decrease by 5.7 percent from 2024 to 2050.

How does this gene therapy work, and what are its limitations?

The therapy uses a modified virus to deliver a DNA sequence into the brain, silencing the gene responsible for producing the toxic huntingtin protein. The 12-18 hour neurosurgery involved limits accessibility due to complexity and anticipated high cost; the therapy's efficacy was shown in 29 patients and not yet peer-reviewed.

What factors contribute to "day zero" droughts, and which regions are most at risk?

Day zero" droughts result from a combination of prolonged rainfall shortages, low river levels, reduced reservoir capacities, and increasing water demand from populations, agriculture, and industries. Regions like the Mediterranean, southern Africa, parts of Asia, and Australia are projected to experience more frequent and prolonged "day zero" events, limiting their recovery capacity. Low-income communities are expected to be disproportionately affected.

How did the research team determine the black hole's mass and what methods were used?

The team used the Gravity+ instrument at ESO's Very Large Telescope, combining light from four telescopes to analyze hot gas spiraling into the black hole. By observing the gas's behavior and interaction with intense radiation, they calculated the black hole's mass and determined that intense radiation prevents it from rapidly gaining mass.
