A Melting Antarctica Could Raise the Sea Level More Than Expected
Rounding Error As rising global temperatures continue to melt the ice in Antarctica, scientists predict that we'll face serious problems in the coming decades — from rising sea levels to devastating storms to temperatures rising even faster because there's less ice to reflect heat . Now, it turns out all those problems could be even worse than scientists predicted, according to research published

Rare earth element mobility in and around carbonatites controlled by sodium, potassium, and silica
Carbonatites and associated rocks are the main source of rare earth elements (REEs), metals essential to modern technologies. REE mineralization occurs in hydrothermal assemblages within or near carbonatites, suggesting aqueous transport of REE.

A universal scaling law of mammalian touch
For most mammals, touch is the first sense to develop. They must feel vibrations on the surface of their skin to enable them to respond to various stimuli in their environment, a process called vibrotaction. But how do mammals perceive these vibrations?

ROS-responsive chitosan-SS31 prodrug for AKI therapy via rapid distribution in the kidney and long-term retention in the renal tubule
The development of drugs with rapid distribution in the kidney and long-term retention in the renal tubule is a breakthrough for enhanced treatment of acute kidney injury (AKI). Here, -serine–modified chitosan (SC) was synthesized as a potential AKI kidney–targeting agent due to the native cationic property of chitosan and specific interaction between kidney injury molecule–1 (Kim-1) and serine.

Of all the mice, rats, and gerbils in Africa, it stood out as the one most adapted for living in water, with water-resistant fur and long, broad feet. That specimen, housed at Chicago's Field Museum, is the only one of its genus ever collected, and scientists think it may now be extinct. But in a new study in the Zoologic

6 feet may not keep musicians safe during the pandemic
Musicians may need more than social distancing to stay safe on stage during the COVID-19 pandemic, according to a new study of exhaled aerosols. Researchers used a high-speed camera to track the movements of exhaled air released by singers and musicians who play wind instruments for Rice University's Shepherd School of Music and for the Houston Symphony. " Social distancing is an important part o

OSIRIS-REx mission researchers detail history of asteroid Bennu
NASA's OSIRIS-REx spacecraft mission, launched on Sept. 8, 2016, is the first U.S. mission designed to retrieve a pristine sample of an asteroid and return it to Earth for further study. The mission's target is Bennu, a carbon-rich near-Earth asteroid that is potentially hazardous, representing an approximately 1 in 2,700 chance of impacting the Earth late in the 22nd century.
