Childhood experiences and environment also have an impact — ScienceDaily

Research based on 5425 citizens’ responses to a questionnaire survey has illuminated that obesity causes are linked to various factors in addition to the individual’s current socioeconomic circumstances, including childhood experiences, particularly those of abuse. The study was carried out by Project Professor TAMORI Yoshikazu (Division of Creative Health Promotion) et al.’s research group at […]

Satellite images confirm uneven impact of climate change — ScienceDaily

University of Copenhagen researchers have been following vegetation trends across the planet’s driest areas using satellite imagery from recent decades. They have identified a troubling trend: Too little vegetation is sprouting up from rainwater in developing nations, whereas things are headed in the opposite direction in wealthier ones. As a result, the future could see […]

Space travel can adversely impact energy production in a cell — ScienceDaily

Studies of both mice and humans who have traveled into space reveal that critical parts of a cell’s energy production machinery, the mitochondria, can be made dysfunctional due to changes in gravity, radiation exposure and other factors, according to investigators at Georgetown Lombardi Comprehensive Cancer Center. These findings are part of an extensive research effort […]

Studies detail impact of mammal species decline in Neotropics

Group led by Brazilian ecologist shows defaunation wiped out 40% of the ecosystem services provided or supported by mammals, such as ecotourism, disease control and soil formation. Large-bodied mammals are disappearing fastest (Brachtyeles arachnoides). Credit: ICMBio Mammal defaunation—the loss of mammals to extinction, extirpation and population decline—in the Neotropics and its adverse effects is the […]

Asteroid Apophis is speeding up as scientists recalculate odds of 2068 impact

Astronomers say they’ll have to keep an eye on the near-Earth asteroid Apophis to see how much of a danger the space rock poses to our planet during a close pass in 2068. But don’t panic: The chances of an impact still seem very low.  Under certain circumstances, the sun can heat an asteroid unevenly, […]
