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.

Nearly half of children on Medicaid lack outpatient follow-up within a month after emergency care for mental health

Only 56% of Medicaid-enrolled children received any outpatient follow-up within 30 days after discharge from the Emergency Department (ED) for a mental health concern, according to a large study published in the journal Pediatrics. Rates of timely follow-up among Black children were particularly low, with 10% fewer receiving an outpatient mental health appointment within 30 days compared to white children.

Study: Pregnant women on ADHD medications shouldn't worry about pediatric neurodevelopmental disorders

Women around the world who have taken medication to treat attention deficit hyperactivity disorder (ADHD) during their pregnancy can now breathe a sigh of relief. There are no differences in rates of neurodevelopmental disorders between children who were exposed and those who were unexposed to stimulant medication in-utero, according to new research conducted by research conducted by the Icahn School of Medicine at Mount Sinai in New York and Aarhus University in Denmark and published February 9 in Molecular Psychiatry.

Lowering blood pressure after clot removal may not be safe, should be individualized

Using blood pressure medications to lower the top number of blood pressure readings (systolic blood pressure) may not be safe or effective among people who have an acute ischemic stroke and undergo a successful mechanical clot removal.

Teens aren't small adults: Rethinking surgical treatment of adolescent clavicle fracture

Until about 15 years ago, most clavicle fractures were allowed to heal with minimal medical intervention. That changed after a 2007 study reported better shoulder function after plate-fixation surgery. Although the study participants were adults, the rate of surgical treatment subsequently increased across all age groups.
