In a new paper in Science, researchers at the University of California, Irvine, Boise State University in Idaho, and East Anglia University in England Worldwide, report that land area consumed by wildfires decreased by 26 percent from 2002 to 2021. During the same time, human exposure to blazes jumped by 40 percent, with Africa accounting for most of it.
In a new study, researchers from UC San Diego designed experiments to show how disordered energy can limit the energy transfer pathway in light-matter interactions, and further demonstrated a strategy to overcome this limitation.In a new study, researchers from UC San Diego designed experiments to show how disordered energy can limit the energy transfer pathway in light-matter interactions, and further demonstrated a strategy to overcome this limitation.
A research team led by a Ph.D. student at the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science has developed a new artificial intelligence (AI) tool that can automatically identify and track tropical easterly waves (TEWs)—clusters of clouds and wind that often develop into hurricanes—and separate them from two major tropical wind patterns: the Intertropical Convergence Zone (ITCZ) and the monsoon trough (MT).
Kyoto, Japan -- The size of our universe and the bodies within it is incomprehensible for us lowly humans. The sun has a mass that is more than 330,000 that of our Earth, and yet there are stars in the universe that completely dwarf our sun.
Stars with masses more than eight times that of the sun are considered high mass stars. These form rapidly in a process that gives off stellar wind and radiation, which could not result in stars of such high mass without somehow overcoming this loss of mass, or feedback. Something is feeding these stars, but how exactly they can accumulate so much mass so quickly has remained a mystery.
Observations of enormous disk-like structures that form around a star -- accretion disks -- had been proposed as the chief way of rapidly feeding young stars. However, a team of researchers from several institutions including Kyoto University and the University of Tokyo, has discovered another possibility.
