Hubble Peers into Messier 30 to Uncover Milky Way’s Past

This image of Messier 30 includes the wide range of wavelengths Hubble can see: ultraviolet, visible, and near-infrared light; each wavelength helps astronomers better understand how various stellar populations formed and evolved.

The globular cluster Messier 30 contains some of the oldest stars in the Milky Way Galaxy. New observations from the NASA/ESA Hubble Space Telescope offer clues to how these stellar populations formed and evolved, and whether some of them originated beyond our home Galaxy. This image of Messier 30 includes the wide range of wavelengths Hubble can see: ultraviolet, visible, and near-infrared light;...

A new genus and species of tapejarid pterosaur has been identified from a specimen in the collections of the Sedgwick Museum of Earth Sciences in Cambridge, England, first described in 1870. The discovery suggests that tapejarids, long associated with Brazil, may have deep roots in Europe.

Researchers from the National University of Singapore, the University of Naples Federico II and the Haus des Meeres aquarium in Austria have filmed the marine animals escaping through tight openings and found a consistent sequence of moves, one that could inform the design of soft robots.

Coffee Drinkers’ Gut Looks Different, Danish Study Finds

People who drink coffee regularly appear to have a more diverse community of gut bacteria and measurable differences in how their digestive tract works, according to a small new study led by University of Copenhagen scientists. Bucci et al. provide integrated evidence linking habitual coffee intake, not only to gut microbiota, but also to direct measurements of gastrointestinal physiology. Image...

Humans and chimpanzees share more than 96% of their protein-coding DNA, yet human brains are roughly three times larger and far more complex. New research led by Lund University scientists suggests that part of the explanation may lie in a viral infection that struck chimpanzee ancestors millions of years ago and never reached ours. Gerdes et al. show that LINC00662, a human-specific transcript expressed...

Stonehenge’s Altar Stone Still Has No Home, Geologists Say

A new analysis by University of South Wales Professor Duncan Pirrie and his colleagues undercuts the leading theory that the 6-ton slab of sandstone came from northeastern Scotland, though the geologists stop short of ruling it out entirely.
