Blessed thistle (Cnicus benedictus) is a plant in the family Asteraceae. For centuries, it has been used as a medicinal herb as an extract or tea, e.g. to aid the digestive system. Researchers have now found a completely novel use for Cnicin. Animal models as well as human cells have...
Invasive species sound off about impending ecosystem changes
Anticipating changes to ecosystems is often at best an educated guess, but what if there was a way to better tune into possible changes occurring? Researchers have discovered that the silent growth of non-native invasive plants can affect the soundscape of an ecosystem. These altered soundscapes, the acoustic patterns of...
‘Itinerant breeding’ in East Coast shorebird species
A study has found direct evidence of a species -- the American woodcock, a migratory shorebird from eastern and central North America -- that overlaps periods of migration and reproduction, a rare breeding strategy known as 'itinerant breeding.'
Surf clams off the coast of Virginia reappear — and rebound
The Atlantic surfclam, an economically valuable species that is the main ingredient in clam chowder and fried clam strips, has returned to Virginia waters in a big way, reversing a die-off that started more than two decades ago. In a comprehensive study of surfclams collected from an area about 45...
Lemur’s lament: When one vulnerable species stalks another
What can be done when one threatened animal kills another? Scientists studying critically endangered lemurs in Madagascar confronted this difficult reality when they witnessed attacks on lemurs by another vulnerable species, a carnivore called a fosa.
‘Forgotten city:’ the identification of Dura-Europos’ neglected sister site in Syria
The Dura-Europos site in modern-day Syria is famous for its exceptional state of preservation. Like Pompeii, this ancient city has yielded many great discoveries, and serves as a window into the world of the ancient Hellenistic, Parthian, and Roman periods. Yet despite the prominence of Dura-Europos in Near Eastern scholarship,...
Toxic chemicals from microplastics can be absorbed through skin
Toxic chemicals used to flame-proof plastic materials can be absorbed into the body through skin, via contact with microplastics, new research shows.
Probiotic feed additive boosts growth, health in poultry in place of antibiotics
The growing need for antibiotic-free products has challenged producers to decrease or completely stop using antimicrobials as feed supplements in the diet of broiler chickens to improve feed efficiency, growth rate and intestinal health. A research team conducted a study of natural feed additives that are promising alternatives to substitute...
Machine learning used to create a fabric-based touch sensor
A new fabric-based touch sensor used machine learning to control mobile apps, video games and other devices while integrated into clothing.
Honey bees experience multiple health stressors out-in-the-field
It's not a single pesticide or virus stressing honey bees, and affecting their health, but exposure to a complex web of multiple interacting stressors encountered while at work pollinating crops, found new research. Scientists have been unable to explain increasing colony mortality, even after decades of research examining the role...
