Research finds that the cellular assembly line that produces proteins can stall with age, triggering a snowball effect that increases the output of misfolded proteins. In humans, clumps of misfolded proteins contribute to age-linked Alzheimer’s and Parkinson’s diseases.
Stanford researchers use one of the most sophisticated structural biology techniques available to investigate how molecular assembly lines maintain their precise control while shepherding growing molecules through a complex, multi-step construction process.
A mathematical model of the body’s interacting physiological and biochemical processes shows that it may be more effective to replace red blood cell transfusion with transfusion of other fluids that are far less in demand.
A sweeping analysis of marine fossils from most of the past half-billion years shows the usual rules of body size evolution change during mass extinctions and their recoveries. The discovery is an early step toward predicting how evolution will play out on the other side of the current extinction crisis.
A new Stanford University study shows rising oxygen levels may explain why global extinction rates slowed down over the past 541 million years. Below 40 percent of present atmospheric oxygen, ocean dead zones rapidly expand, and extinctions ramp up.
A new study offers up a more realistic modeling of the rise and fall of fads as culture evolves and is transmitted to new generations, including an examination of the role “influencers” play in shaping what’s popular.
