A New Zealand study suggests that sugary drinks contribute to an obesogenic environment, leading people to make unhealthy food choices. The researchers recommend implementing a sugar tax to encourage industry reformulation and individual responsibility for healthy consumption.
Some physicists argue that spacetime may emerge from processes closer to reality, such as quarks and hadrons. The concept of spacetime has puzzled humanity for millennia, with some theories suggesting it's a dynamic creation while others propose it's an absolute arena for events.
Scientists have reconstructed the monsoon's precipitation history over the past 1 million years using sediment cores from the eastern Indian Ocean. The results show that the monsoon was weaker during peak ice ages and strongest during interglacial warm periods, with fluctuations in the Earth's axis inclination playing a subordinate role.
Researchers have developed a mouse model that closely replicates human diabetic nephropathy, revealing a key role for immune and inflammatory responses in promoting kidney damage. This finding suggests targeting these pathways may be useful for preventing or slowing the development of diabetic nephropathy.
Research by Oregon State University scientists shows that large terrestrial carnivores can lead to improved stream structure and function in Yellowstone National Park. The return of wolves and cougars has resulted in increased willow height, canopy cover, and stream-bank stabilization, indicating a recovering riparian/aquatic ecosystem.
The study found that monarch caterpillars and butterflies have declined by 80 percent since 2005 in North Central Florida, mirroring the decline in Mexico. The researchers blame shrinking native milkweed populations and glyphosate use in agricultural fields for the decline.
A study by researchers at the National Research University Higher School of Economics found that people tend to attribute their happiness to internal factors such as personality traits and control over their lives. However, when they are unhappy, they often blame external factors outside of their control.
