Read MoreCooler, higher locales may not be very welcoming to some hummingbirds trying to escape rising temperatures and other effects of climate change. Anna’s hummingbirds live no higher than about 2,600 meters above sea level. If the birds attempt to expand their range to include higher altitudes, they may struggle to fly well in the thinner […]

Read MoreCells are compartmentalized by membranes, and proteins present in these membranes play an important role in transporting cellular information. For proper function of these proteins to occur, a tertiary protein structure must be formed through the correct folding process. In a study published in Nature Chemical Biology, the folding process of a glucose transporter—a complex […]
Read MoreA recently developed catalyst for breaking down plastics continues to advance plastic upcycling processes. In 2020, a team of researchers led by Ames Laboratory scientists developed the first processive inorganic catalyst to deconstruct polyolefin plastics into molecules that can be used to create more valuable products. Now, the team has developed and validated a strategy […]
Read MoreProtein aggregation is a real problem in the living cell. It’s become clear over the years that some proteins in particular are more prone to this behavior than others, with particular sequence motifs sometimes being signs of incipient trouble. But like much else in biology, there’s a trade-off: the same properties that make a protein […]
Read MoreA massive urban landscape that contained interconnected campsites, villages, towns and monumental centers thrived in the Amazon rainforest more than 600 years ago. In what is now Bolivia, members of the Casarabe culture built an urban system that included straight, raised causeways running for several kilometers, canals and reservoirs, researchers report May 25 in Nature.
