Are we missing a crucial component of sea-level rise?

Credit: Unsplash/CC0 Public Domain Recent efforts using computational modeling to understand how melting ice in Antarctica will impact the planet’s oceans have focused on ice-sheet geometry, fracture, and surface melting—processes that could potentially trigger or accelerate ice-sheet mass loss. Now, researchers from Stanford University have identified an additional process that could have a similarly significant … Read more

Stone Age skeleton missing foot may show oldest amputation

Dr Tim Maloney and Andika Priyatno work at the site in a cave in East Kalimantan, Borneo, Indonesia, March 2, 2020. The remains, which have been dated to 31,000 years old, mark the oldest evidence for amputation yet discovered. And the prehistoric “surgery” could show that humans were making medical advances much earlier than previously … Read more

Missing grizzly bear toes result in call to change practices

Wildlife Society Bulletin (2022). DOI: 10.1002/wsb.1343″ width=”800″ height=”529″/> Animals detected with amputated toes through research captures in the Elk Valley (A–D), and anecdotal evidence of grizzly bears with traps on their feet (E–G). Each letter in AD represents one of the 4 unique individuals detected with amputated toes. An X-ray of the foot of EVGM55, … Read more

Revealed missing step in lipid formation could enable detection of past climates

A team from Penn State and the University of Illinois Urbana-Champaign has determined the missing step in the formation of a molecule called GDGT, which is a promising candidate for use as an indicator of past climate. The team determined the X-ray crystal structure of an enzyme that facilitates this process called GDGT/MAS—shown here bound … Read more

The missing links: Finding function in lincRNAs

Kyle Palos examines some Arabidopsis growing in a BTI growth chamber. Credit: Boyce Thompson Institute. Genomes contain regions between protein-coding genes that produce lengthy RNA molecules that never give rise to a protein. These long intergenic non-coding RNAs (lincRNAs) are thought to have important functions, such as regulating responses to environmental change. However, a paucity … Read more
