New research shows that sunspots and other active regions can change the overall solar emissions. The sunspots cause some emissions to dim and others to brighten; the timing of the changes also varies between different types of emissions. This knowledge will help astronomers characterize the conditions of stars, which has important implications for finding exoplanets around those stars.
An international research team led by Shin Toriumi at the Japan Aerospace Exploration Agency added up the different types of emissions observed by a fleet of satellites including “Hinode” and the “Solar Dynamics Observatory” to see what the Sun would look like if observed from far away as a single dot of light like other stars.
The team investigated how features like sunspots change the overall picture. They found that when a sunspot is near the middle of the side of the Sun facing us, it causes the total amount of visible
An Oxford economist recommends the best books to get up to speed on the future of work.
Will robots take all our jobs? And if they do, will that be a good thing or a bad thing? How will we have to change our politics, education system, and economy to respond to tech-based disruption of the labor market?

Everyone from Elon Musk and Bill Gates to Stephen Hawking and a host of presidential candidates has loudly disagreed about these important questions. If you’re not an economist or an A.I. expert, the debates can be confusing. How can you direct your business, your kid’s education, or your own learning if even the experts can’t agree on what the future of
Through the development of new technology, University of Minnesota researchers have developed a method that allows scientists to understand how a fruit fly’s brain responds to seeing color. Prior to this, being able to determine how a brain responds to color was limited to humans and animals with slower visual systems. A fruit fly, when compared to a human, has a visual system that is five times faster. Some predatory insects see ten times faster than humans.
“If we can understand how seeing color affects the brain, we will be able to better understand how different animals react to certain stimuli,” said Trevor Wardill, the study’s lead author and assistant professor in the College of Biological Sciences. “In doing so, we will know what interests them most, how it impacts their behavior, and what advantages different color sensitivities may give to an individual’s or a species’ survival.”
