The Stanford whale biologist discusses a pod of orcas taking down a blue whale – “arguably one of the most dramatic and intense predator-prey interactions on the planet.”
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.
More than a century of attentive groundskeeping has turned the Stanford campus into a museum of mathematical phylogenetics, says Noah Rosenberg, creator of the Stanford X-Tree Project.
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.
Research on whale feeding highlights how the precipitous decline of large marine mammals has negatively impacted the health and productivity of ocean ecosystems.
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.
