CDC sharply overestimates maternal death rate, new study finds

2024-03-13
Maternal death rates in the United States may be sharply overstated as a result of faulty surveillance techniques, according to an analysis by researchers at Rutgers Health and other universities. The National Vital Statistics System (NVSS) of the Centers for Disease Control and Prevention (CDC) estimates that maternal death rates have more than tripled over the last two decades to 32.9 deaths per 100,000 live births in 2021 – substantially more than in any other wealthy nation. The new study that looked at all deaths in the United States from 1999 to 2021 published in The American Journal of Obstetrics and Gynecology reports consistent death rates of slightly ...

Who knew that eating poo was so vital for birds’ survival?

2024-03-13
We all know that the early bird gets the worm, but new research shows they turn to something far more nutritious for their breakfast. Poo – either their own, or from other birds – provides them with essential nutrients, energy, and helps them adapt to new environments and seasonal variations, especially when they are developing. New research led by the University of South Australia and published in Biological Reviews explains how eating faeces (known as coprophagy) shapes wild birds’ digestive tracts (gut biota), enabling them to absorb lost or deficient nutrients and adjust to seasonal variations in food sources. This ...

AI analysis of historical satellite images show USSR collapse in 1990s increased methane emissions, despite lower oil and gas production

AI analysis of historical satellite images show USSR collapse in 1990s increased methane emissions, despite lower oil and gas production
2024-03-12
The collapse of the former Soviet Union in 1991 had social, political and economic effects worldwide. Among them was a suspected role in slowing human-generated methane emissions. Methane had been rising steadily in the atmosphere until about 1990. Atmospheric scientists theorized that economic collapse in the former USSR led to less oil and gas production, and thus a slowdown in the rise of global methane levels, which has since resumed. But new University of Washington research uses early satellite records to dispute that assumption. The study, published March 12 in the ...
