Spider exploits firefly’s flashing signals to lure more prey
Fireflies rely on flashing signals to communicate to other fireflies using light-emitting lanterns on their abdomens. In fireflies of the species Abscondita terminalis, males make multi-pulse flashes with two lanterns to attract females, while females make single-pulse flashes with their one lantern to attract males. Now researchers have evidence that...
Mining the microbiome: Uncovering new antibiotics inside the human gut
Researchers surveyed the gut microbiomes of nearly 2,000 people, discovering dozens of potential new antibiotics. The lead candidate, prevotellin-2, demonstrated anti-infective capabilities on par with polymyxin B, an FDA-approved antibiotic used today to treat multidrug-resistant infections, suggesting that the human gut microbiome may contain antibiotics that will someday find clinical...
The bee’s knees: New tests created to find fake honey
Researchers have developed new ways to detect sugar syrup adulteration in honey, paving the way for fast and accurate tests to discover fake products.
Ancient DNA reveals Indigenous dog lineages found at Jamestown, Virginia
Previous scientific studies have indicated that North American dog lineages were replaced with European ones between 1492 and the present day. To better understand the timing of this replacement, researchers sequenced mitochondrial DNA from archaeological dogs. Their findings suggest a complex social history of dogs during the early colonial period.
New twist on synthesis technique promises sustainable manufacturing
Researchers developed a new method known as flash-within-flash Joule heating (FWF) that could transform the synthesis of high-quality solid-state materials, offering a cleaner, faster and more sustainable manufacturing process.
Scientists discover phenomenon impacting Earth’s radiation belts
Two scientists discovered a new type of 'whistler,' an electromagnetic wave that carries a substantial amount of lightning energy to the Earth's magnetosphere.
Decoding mysterious seismic signals
Geophysicists find link between seismic waves called PKP precursors and anomalies in Earth's mantle that are associated with hotspots associated with volcanism on the surface.
Tracking down the asteroid that sealed the fate of the dinosaurs
The asteroid that led to the extinction of the dinosaurs 66 million years ago probably came from the outer solar system.
Rural Migration Links to Land Use, Climate Change Need More Attention, Scientists Say
Climate and other environmental changes sometimes drive people to migrate, especially if the land no longer supports a population’s way of life.
