First Look: When an increase in predator numbers can lead to an increase in prey

When numbers of predators and their prey rise and fall over time, one would expect peaks in prey abundance to precede spikes in predator abundance. Now scientists find the opposite, counter-intuitively, also can happen. Predator numbers can rise before prey … Continue reading

New mathematical techniques might allow for X-ray nanocrystallography

The discovery of the double-helix structure of DNA revealed key insights on how life and heredity works, helping kick off the modern era of genetics. This and many other breakthroughs were achieved via a technique known as X-ray crystallography, but … Continue reading

Understanding the occurrence of rare events

The rich can get richer more often than traditional statistics would predict. This is an example of a statistical distribution with a “heavy tail.” These patterns are common in the real world, including everything from “hundred-year floods” to stock market … Continue reading
