ASU researchers found that genetics alone cannot explain the origins of eusociality. Inside an ant colony, queens reproduce while workers care for young and maintain a society built around shared labor. For more than six decades, evolutionary biologists have debated whether this extraordinary arrangement, known as eusociality, arose partly because ants, bees, and wasps share [...]Weather extremes may be contributing to an unusually quiet summer for Britain’s ecologically important social wasps. A summer picnic often feels complete only when a wasp arrives to investigate the food. Common social wasps are familiar warm-weather visitors, whether they are circling outdoor meals or building an unwanted nest in the loft. Summer 2026, however, [...]More than 150 years after Charles Darwin first wondered whether certain sticky-leaved Saxifraga plants might be secretly carnivorous, Kunming Institute of Botany researcher Tao Deng and colleagues say they have finally confirmed it.

One of nature’s most mysterious predators isn’t a mammal stalking remote forests or jungles, nor any large, finned creature lurking in the ocean depths: it is a bizarre little plant that grows only in certain wetland areas along the East Coast of the United States.
With the distinctive hinged leaves that it uses to capture insects, the Venus flytrap is one of nature’s most curious offerings. The small bog-dwelling plant owes its success to the way it can generate an inviting aroma with the nectar it produces, which lures insects. Then, with the help of tiny follicles that act as triggers, the insects become trapped within the flytrap’s leaves as they close like jaws around its prey.
Scientists have long been perplexed by exactly how these plants can react quickly enough to capture even some of the fastest flying insects. Even Charles Darwin seemed baffled by these curious examples of carnivorous flora, describing them as “a plant [that] should secrete, when properly excited, a fluid containing an acid and ferment, closely analogous to the digestive fluid of an animal.”
While the exact mechanism that allows the mysterious Venus flytrap to carry out its distinctive method of feeding has long remained unknown, new research is finally shedding light on the mystery.
According to recent experiments detailed in a new study, when the hair-trigger mechanism is activated on these plants, cells on the jaw-like leaves soften, which initiates the closing movement within fractions of a second, trapping any insects unlucky enough to have landed searching for nectar.
Dr Yoël Forterre, a physicist at the French National Centre for Scientific Research (CNRS) and Aix-Marseille University, says that this movement had been so mysterious to Darwin that “he was convinced that the plant had a muscle inside, but plants do not have muscles and they do not have nerves.”
“For more than a century there have been many hypotheses,” Forterre, senior author of the recent study, said. “It’s very surprising that plant cell walls can tune their mechanical properties so fast.”
One of the primary issues with resolving the plant’s curious mechanism involved overcoming challenges associated with measuring such a remarkably fast system of movement, let alone one in a plant, which possesses none of the usual mechanisms nature relies on for such activities.
Equally perplexing is that the Venus flytrap seemingly recognizes when an accidental trigger has been initiated, rather than a successful capture of an insect.
“If you close it accidentally with a drop of water, it will close and then reopen the next day,” Forterre says. “If it catches an insect, it has to digest it and dissolve the skeleton, which will take several weeks.”
In experiments Forterre and his colleagues performed, dental glue was used to secure the plant’s leaves, which allowed for the normal trigger mechanisms to be engaged, but left the plant’s leaves open throughout the process.
Past research had already shown that electrical signals had been detected coinciding with the manipulation of the trigger hairs present on the plant’s leaves, in which this sudden surge of electricity “activates” the plant’s closing mechanism within a fraction of a second.
Applying a new approach, Forterre and colleagues used the metallic tip of a nanoindenter, devices used to make very small mechanical measurements. Applying the device to the outer leaves revealed that its normal stiffness appeared to soften significantly once the hair mechanisms were triggered.
The reason this occurs, according to Forterre, is that the cells themselves temporarily become more flexible. Past theories suggested that the movement was initiated by the movement of water contained within the leaf.
The newly-identified mechanism reveals a process very similar to the function of a plunger, which, if inverted, will flip back to its normal position when pressure is applied.
Forterre says he is unaware of any similar plant in nature that displays such unusual mechanical properties, which he says allows the Venus flytrap to initiate a “very rapid change of mechanical properties of the cells.”
“I’ve been obsessed by this for 20 years,” Forterre recently told The Guardian, noting that “as a physicist, I thought we should understand the motor, the forces.”
Now, thanks to his team’s findings, one of the plant kingdom’s strangest inhabitants has finally revealed its secrets.
The team’s new study, “Fast cell wall softening causes Venus flytrap closure,” appeared in Science on June 11, 2026.
