 Journal of the American Chemical SocietyCWRU-led scientists build material that mimics squid beak Researchers led by scientists at Case Western Reserve University have turned to an unlikely model to make medical devices safer and more comfortable -- a squid's beak. Many medical implants require hard materials that have to connect to or pass through soft body tissue. This mechanical mismatch leads to problems. But the beak, which boasts a mechanical gradient that can act as a shock absorber, may provide a solution.

NatureAncient pool of warm water questions current climate models A huge pool of warm water that stretched out from Indonesia over to Africa and South America four million years ago suggests climate models might be too conservative in forecasting tropical changes.

NatureAncient climate questions could improve today's climate predictions Climate models for the early Pliocene might be missing key processes. If researchers can uncover these missing processes, they can apply them to models of modern climate and improve future climate predictions.

NatureThin clouds drove Greenland's record-breaking 2012 ice melt If the sheet of ice covering Greenland were to melt in its entirety tomorrow, global sea levels would rise by 24 feet. Three million cubic kilometers of ice won't wash into the ocean overnight, but researchers have been tracking increasing melt rates since at least 1979. Last summer, however, the melt was so large that similar events show up in ice core records only once every 150 years or so over the last four millennia.

Journal of ClimateRising temperature difference between hemispheres could dramatically shift tropical rain patterns UC Berkeley and University of Washington researchers found that changes in the interhemispheric temperature difference during the 20th century were linked to catastrophic changes in tropical rainfall. They predict that in the future, the rising difference could have major effects on tropical rainfall patterns, generally shifting seasonal rains such as monsoons northward.

Nature Climate ChangeNew models predict drastically greener Arctic in coming decades New research predicts that rising temperatures will lead to a massive "greening," or increase in plant cover, in the Arctic. In a paper published on March 31 in Nature Climate Change, scientists reveal new models projecting that wooded areas in the Arctic could increase by as much as 50 percent over the next few decades. The researchers also show that this dramatic greening will accelerate climate warming at a rate greater than previously expected.

Proceedings of the National Academy of SciencesRecord-breaking 2011 Lake Erie algae bloom may be sign of things to come The largest harmful algae bloom in Lake Erie's recorded history was likely caused by the confluence of changing farming practices and weather conditions that are expected to become more common in the future due to climate change.

Proceedings of the National Academy of SciencesExtreme algal blooms: The new normal? A research team, led by Carnegie's Anna Michalak, has determined that the 2011 record-breaking algal bloom in Lake Erie was triggered by long-term agricultural practices coupled with extreme precipitation, followed by weak lake circulation and warm temperatures. The team also predicts that, unless agricultural policies change, the lake will continue to experience extreme blooms.

Rice's Laura Segatori wins NSF CAREER Award Some human cells forget to empty their trash bins, and when the garbage piles up, it can lead to Parkinson's disease and other genetic and age-related disorders. Scientists don't yet understand why this happens, and Rice University engineering researcher Laura Segatori is hoping to change that, thanks to a prestigious five-year CAREER Award from the National Science Foundation.

Nature MaterialsPenn researchers show stem cell fate depends on 'grip' A team of researchers from the University of Pennsylvania has generated new insight on how a stem cell's environment influences what type of cell a stem cell will become. They have shown that whether human mesenchymal stem cells turn into fat or bone cells depends partially on how well they can "grip" the material they are growing in.

Their results, published Apr. 8 in the journal Current Biology, could ultimately lead to new ways to heal wounds and deliver stem cell therapies.

Journal of Geophysical ResearchSummer melt season is getting longer on the Antarctic Peninsula, new research shows. New research from the Antarctic Peninsula shows that the summer melt season has been getting longer over the last 60 years. Increased summer melting has been linked to the rapid break-up of ice shelves in the area and rising sea level.
