High-school students in a Mississippi district have been accepted into a summer internship program. The program was launched as part of an effort to help students prepare for college and career.

Water security may be in more danger than many think, per research based on observations from a NASA satellite. A map based on the data reveals "persistent, distinct patterns that define emerging classes of water 'haves' and 'have-nots' around the world," writes Jay Famiglietti of the University of Saskatchewan.

An Alabama school district recently approved the addition of three career and technical education dual-enrollment courses. Plans include courses in child development, computer science and welding.

HVAC employers recently talked to students at the Leominster, Mass., Center for Technical Excellence Innovation. Ace Service General Manager Sally Murphy and Wilson Bros. Heating and Air Conditioning owner Tom Wilson advised students of the opportunities they could find in the HVAC industry.

An Iowa high school's students, who are members of their school's chapter of the National FFA Organization, are pitching in to help protect their communities from flooding. The students are part of an effort to fill sandbags for distribution to communities.

The idea of moralizing gods that monitor and punish people for bad behavior arose in ancient societies once they grew to over a million people, according to a study published online in Nature. "Our research suggests that religion is playing a functional role throughout world history, helping stabilize societies," says researcher Patrick Savage.

Ryugu, the near-Earth asteroid being studied by Japan's Hayabusa2 spacecraft, is likely a broken-off piece of either Polana or Eulalia, asteroids that are larger and farther away, according to findings presented at the Lunar and Planetary Science Conference. Researchers will get a clearer idea of where Ryugu originated when Hayabusa2 brings back samples from the asteroid's surface, expected late next year.

The early growth response gene -- EGR -- is responsible for the whole-body regeneration of three-banded panther worms that had been severed into two or three pieces, according to findings published in Science. Researchers mapped the worms' genome and monitored gene activity after the worms had been cut up to see how the regenerated worms formed.

The anesthesia drug propofol may reduce the clarity of distressing memories after 24 hours have elapsed, a study published in Science Advances suggests. The drug could one day be useful in treating post-traumatic stress disorder, but only in a limited way, since older memories are less likely to change, researchers say.

A Canadian study in Pediatric Obesity showed that teens with obesity who had lost 30% or more of excess weight three months after bariatric surgery had a higher likelihood of having 50% or higher excess weight loss at 12 months and 24 months. Researchers also found that less than 30% excess weight loss at three months was tied to a significantly reduced rate of excess weight loss at 24 months.
