Chitin, a chain of repeating sugar molecules, is the main building block of fungal cell walls. When fungi grow or are broken down, fragments of chitin chains of different lengths end up in the soil, and plants detect them to monitor the microbes around them.

Better together? Coral fusion could throw bleached reefs a lifeline
When corals are stressed by pollution, high water temperatures or other environmental changes, they can lose the microscopic algae living inside them and on which they depend for food. As a result, they turn white, a phenomenon known as coral bleaching. They will not die straight

Lion tracks from the ice age: How two ways of seeing brought ancient animals to life
The coastline near the southern tip of Africa looked vastly different between about 400,000 years ago and 70,000 years ago, compared with today. At times it lay as much as 100km (62 miles) south of its present location, exposing the vast Palaeo-Agulhas Plain, which contained an e

New DNA sequencing methods detect rare mutations acquired as bodies grow and age
Somatic mutations, the DNA changes that occur as our bodies grow and age, not only hold an important key to cancer but are emerging as the seeds of a wide range of common, noncancerous diseases. The Somatic Mosaicism across Human Tissues (SMaHT) Network, a National Institutes of
