New technique maps large-scale impacts of fire-induced permafrost thaw in Alaska

About 40 percent of interior Alaska is underlain by ice-rich permafrost—permanently frozen grounds made up of soil, gravel and sand—bound together by ice. Certain conditions, such as climate warming, have intensified tundra wildfires which have profound implications for permafrost thaw.

From glacier ice, a wealth of scientific data

Perched next to a river near a glacier's edge in Greenland, Penn biogeochemist Jon Hawkings and Jack Murphy, senior research coordinator in Hawkings' lab, scooped up samples of frigid meltwater, careful to seal the bottles quickly to minimize any chance of contamination. The two spent nearly a month in Greenland this past summer. The fieldwork, while scenic, isn't glamorous. "You're standing in front of a massive glacier submerging your hands in zero degrees Celsius water; it's freezing and windy and dusty," Murphy says. "We have to get creative to get clean samples."

Researchers identify new molecular mechanism key to planarian regeneration

Planaria are freshwater flatworms that have become a key model for studying regeneration and stem cells, as they can regenerate any part of the body, even the head. But how does the animal know what part of its body is missing and what kind of tissue it needs to regenerate?

Chinese astronomers discover an isolated dark dwarf galaxy

Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), Chinese astronomers have detected a new galaxy, which received designation FAST J0139+4328. The newfound galaxy is isolated, has a relatively low stellar mass, and is dominated by dark matter. The discovery was detailed in a paper published February 6 on the arXiv pre-print server.

New report exposes steep declines in data science skills among fourth- and eighth-graders across America

A new report from the Data Science 4 Everyone coalition reveals that data literacy skills among fourth and eighth-grade students have declined significantly over the last decade even as these skills have become increasingly essential in our modern, data-driven society.
