Smaller salamander species associated with smaller genomes

The world’s tiniest salamanders are so small that some body parts appear to get short shrift. Those in the genus Thorius, for example, have heads that are “mind bogglingly small, maybe half the size of a pencil eraser,” says herpetologist … Continue reading

Interdisciplinary study brings a humanist perspective to research on land use change

Decades ago, Brazil’s northeastern State of Bahia produced much of the world’s cocoa for chocolate. Most farms grew their cacao trees interspersed with other native trees, in dense agricultural forests. Children played at the forest edges. Today those children are … Continue reading

Model suggests how evolution shapes ecological networks among species

The natural world is filled with networks. Predator and prey, flower and pollinator—each interacting pair forms a link in a networked community of organisms. Now, a French research team has developed a model that explores how evolution may help shape … Continue reading

Plants sense temperature with help of elegant protein

How plants sense temperature is a longstanding and little-understood question. Researchers have discovered some of the mechanisms involved. A recent study in Nature adds a new mechanism—among the first in which the biophysical behavior of a single protein regulates the … Continue reading

The hippocampus has brief but critical role in early task learning

How the brain learns new tasks is among the biggest and oldest questions in neuroscience. A recent study in Nature Neuroscience offers a new, potentially key part of the answer: the dorsal hippocampus is involved in the earliest stages of … Continue reading

Deep-sea mussels still show biological rhythms tracking sunlight, tides

Like many land animals, marine organisms follow daily and seasonal clocks—in the water, those clocks are set by the cadence of the sun and the moon. But researchers hadn’t known if deep-sea creatures also exhibit biological rhythms, tucked away in … Continue reading

People who are likely to dismiss journalism as “fake news” tend to believe the world is predictable

The notion of “fake news” spread like wildfire in the United States after the 2016 election. Recent research in Psychological Science tried to determine what psychological factors drove this concept—generally defined as the suspicion that politically-biased news outlets produce deliberately … Continue reading

Seasonality shapes coevolution of parasites and hosts

Parasites and their hosts coevolve in an arms race influenced by environmental conditions. Seasonal change, for example, can shape the course of evolution, but precisely how has been something of a mystery. A recent study used lab experiments and mathematical … Continue reading

Country-level assessment hides big variations in soy’s carbon footprint

Analysts usually estimate a crop’s carbon footprint based on country-level factors. But that formulation isn’t adequate, according to a new analysis of soy exports from Brazil. Published in Global Environmental Change, the study tracked soy from specific production sites in … Continue reading
