- Pufferfish at the ‘Beak’ of Evolution: Why Humans Don’t Continuously Replace Their Teeth. - “Prickly pufferfish could hold the key to why humans do not continually replace their teeth and may lead to advances in dental therapies.”

In Metallic Glasses, Researchers Find a Few New Atomic Structures. - “Drawing on powerful computational tools and a state-of-the-art scanning transmission electron microscope, a team of University of Wisconsin-Madison and Iowa State University materials science and engineering researchers has discovered a new nanometer-scale atomic structure in solid metallic materials known as metallic glasses.”
- Greater Insight Into Earthquake Cycles. - “For those who study earthquakes, one major challenge has been trying to understand all the physics of a fault — both during an earthquake and at times of “rest” — in order to know more about how a particular region may behave in the future. Now, researchers at the California Institute of Technology (Caltech) have developed the first computer model of an earthquake-producing fault segment that reproduces, in a single physical framework, the available observations of both the fault’s seismic (fast) and aseismic (slow) behavior.”
- Low-Cost Nanosheet Catalyst Discovered to Split Hydrogen from Water. - “Hydrogen gas offers one of the most promising sustainable energy alternatives to limited fossil fuels. But traditional methods of producing pure hydrogen face significant challenges in unlocking its full potential, either by releasing harmful carbon dioxide into the atmosphere or requiring rare and expensive chemical elements such as platinum.”
- Potential Instability in West Antarctic Ice Sheet from Newly Discovered Basin Size of New Jersey. - “Using ice-penetrating radar instruments flown on aircraft, a team of scientists from the U.S. and U.K. have uncovered a previously unknown sub-glacial basin nearly the size of New Jersey beneath the West Antarctic Ice Sheet (WAIS) near the Weddell Sea. The location, shape and texture of the mile-deep basin suggest that this region of the ice sheet is at a greater risk of collapse than previously thought.”
