Dial-a-Frog -- Researchers Develop the 'FrogPhone' to Remotely Call Frogs in the Wild

Researchers have developed the 'FrogPhone', a novel device which allows scientists to call up a frog survey site and monitor them in the wild. The FrogPhone is the world's first ... read more

'Conductor' Gene Found in Plant Root Stem Cell 'Orchestra'

Researchers lift the veil on the 'conductor' plant root stem cell gene that helps orchestrate and coordinate stem cell division of different root stem cell types, ensuring the harmonic ... read more

Island 'Soundscapes' Show Potential for Evaluating Recovery of Nesting Seabirds

An important tool for monitoring seabird populations involves acoustic sensors deployed at nesting sites to record sounds over long periods of time. But analysis of the recordings to identify and ... read more

Artificial Cells Act More Like the Real Thing

Protocells -- artificial cells -- that are active and mimic living cells by moving independently and that are biocompatible and enzymatically active are now possible using an improved ... read more

Rats Exchange Information About Danger in a Reciprocal Fashion

Rats exchange information about danger in a reciprocal fashion, and this information transfer is at least partially mediated by a brain region called the anterior cingulate ... read more

Dull Teeth, Long Skulls, Specialized Bites Evolved in Unrelated Plant-Eating Dinosaurs

Herbivorous dinosaurs evolved many times during the 180 million-year Mesozoic era, and while they didn't all evolve to chew, swallow, and digest their food in the same way, a few specific ... read more

Nervous System Doesn't Merely Detect Salmonella, It Defends the Body Against It

Study in mice shows the nervous system not only detects the presence of Salmonella in the gut but actively stops the organism from infecting the ... read more

How Flowers Adapt to Their Pollinators

The first flowering plants originated more than 140 million years ago in the early Cretaceous. They are the most diverse plant group on Earth with more than 300,000 species. Evolutionary biologists ... read more

New Marker for Insecticide Resistance in Malaria-Carrying Mosquitoes

Researchers have genetically modified malaria carrying mosquitoes in order to demonstrate the role of particular genes in conferring insecticide ... read more

Detailed Insight Into Stressed Cells

When cells are stressed, they initiate a complex and precisely regulated response to prevent permanent damage. One of the immediate reactions to stress signals is a reduction of protein synthesis ... read more

New Study Hints at Complex Decision Making in a Single-Cell Organism

In an effort to replicate an experiment conducted over a century ago, researchers present evidence confirming at least one single-cell organism -- the trumpet-shaped Stentor roeselii -- exhibits a ... read more
