Exploring the solar wind with a new view of small sun structures — ScienceDaily

Scientists have combined NASA data and cutting-edge image processing to gain new insight into the solar structures that create the Sun’s flow of high-speed solar wind, detailed in new research published today in The Astrophysical Journal. This first look at relatively small features, dubbed “plumelets,” could help scientists understand how and why disturbances form in […]

Do children view punishment as rehabilitative? A new study takes a look

The United States incarcerates more residents than any other country, however there is limited research that examines how people view such punishment, and whether views about punishment change with development. Previous research on this topic raises two very different possibilities: 1) children are typically more optimistic than adults, making them more likely to report that […]

Harm prevention policies must take the long view, say experts — ScienceDaily

The evidence for the harmful effects of alcohol on brain health is compelling, but now experts have pin-pointed three key time periods in life when the effects of alcohol are likely to be at their greatest. Writing in The BMJ today, researchers in Australia and the UK say evidence suggests three periods of dynamic brain […]

A Thanksgiving sun treat: Big sunspot rotates into view

A group of sunspots has emerged on the Earth-facing side of the sun, just in time for Thanksgiving.  Researchers identified the sunspots before they were even visible from Earth, via a technique called helioseismology, which uses acoustic waves beneath the sun’s surface to probe for the features. “We measured a change in acoustic signals on […]

A Precise Mosaic View of Mars’s South Pole

To get a precise view of a planet’s surface, scientists can build a mosaic using images captured by cameras mounted on an orbiting spacecraft. This process requires accounting for how the spacecraft and its camera were oriented when each photo was taken, as well as how that positioning corresponds to existing topographic data. […]
