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

Inner Workings: Researchers race to develop in-home COVID-19 testing, a potential game-changer
For most people, a COVID-19 test entails a swab up the nose in a doctor’s office or drive-in site. The sample then goes out to a lab. Results come back within a few days to a week—a waiting period that’s … 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

Insects, not just wind, offer an ancient mechanism of orchid seed dispersal
On Yakushima Island, at the southern tip of Japan, an orchid employs a very unusual strategy to disperse its seeds. Crickets visit the orchid at night, eat its fruits, and defecate the seeds in the vicinity. The discovery, reported recently … 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

Snake venom evolved in fits and spurts
The cocktail of toxins in snake venom experienced constant change with pulses of rapid evolution over the last 60 million years, according to a recent study in the Proceedings of the Royal Society B. Venom, the researchers report, has changed … Continue reading

Trends in conservation funding track popular narratives about the illegal wildlife trade
Trends in conservation funding are changing, according to a recent study in World Development. “We see a shift toward funding conservation work that’s increasingly about combatting wildlife trafficking,” says coauthor Jared Margulies, a human-environment geographer at the University of Alabama … Continue reading
