A trap for nematodes
Filariae, slender but sometimes up to 70-centimeter-long nematodes, can set up residence in their host quite tenaciously and cause serious infectious diseases in the tropics. The tiny larvae of the worms are usually transmitted from person to person.....»»
Researchers invent trap for capturing and comparing individual bacterial cells
All hospitals battle an invisible threat: Pseudomonas aeruginosa. It is a type of bacteria that affects thousands of patients each year in intensive care units, where it can cause sepsis, pneumonia and other types of infections......»»
The tiniest hitchhikers: Nematodes leap onto bumblebees via electric fields
Worms lept at an average speed of 0.86 meters per second, close to human walking speed. A nematode (C. elegans) jumps onto a bumblebee along an electrical field to hitch a ride. Credit: Chiba et al., 2023.....»»
Scientists verify trap-release-amplify model by reproducing electromagnetic waves on Mars
Chinese scientists have reproduced the observed whistler mode chorus waves on Mars using data from the Mars Atmosphere and Volatile Evolution (MAVEN) mission and compared them with phenomena on the Earth. They found that both Mars and Earth exhibit w.....»»
Scientists reveal regulation mechanism of soybean cyst nematode responses to chemical signals
Soybean cyst nematode (SCN, Heterodera glycines Ichinohe), is a devastating pathogen in soybean. The infective juveniles of nematodes can use phytochemical signals (semiochemicals) released into the rhizosphere as important cues for host seeking, hos.....»»
Experiments with nematodes find they need a nap to consolidate odor memories
A team of biomedical researchers from the University of California, San Francisco, San Jose State University and the University of Pennsylvania has found that nematodes need sleep in order to consolidate their odor memories by remapping olfactory syn.....»»
Strategic city planning can help reduce urban heat island effect
The tendency of cities to trap heat—a phenomenon called the "urban heat island," often referred to as the UHI effect—can lead to dangerous temperatures in the summer months, but new Penn State research published in Buildings suggests that certain.....»»
Creating kitty litter from soy waste
Scientists with the Agricultural Research Service (ARS) are building a better mouse trap when it comes to cat litter. And in the process, they hope to kill two birds with one stone......»»
Differing device personalities come together for future quantum computing networks
We're building the tools to trap ions and watch them glow (or not). The art-deco-esque device shown above is a combined trap for ions (charged atoms) and detector for individual photons (particles of light). When you hold an ion in place and hit it w.....»»

Ice can trap pollutants and accelerate their breakdown, with troubling environmental consequences......»»
A surprising way to trap a microparticle
When physicists recently steered a tiny microparticle toward a cylindrical obstacle, they expected one of two outcomes to occur. The particle would either collide into the obstacle or sail around it. The particle, however, did neither......»»
Medieval manuscripts may have described “new” whale feeding trick centuries ago
Old Norse hafgufa, medieval bestiaries seem to depict "trap feeding." Enlarge / A digital reconstruction of a humpback whale engaged in trap feeding. (credit: John McCarthy, Flinders University) About 10 years ago, marin.....»»
Plant and animal species that adapt quickly to city life are more likely to survive, finds research
It's five o'clock on a summer morning in Winnipeg. Our research team is unloading a series of small traps from the trunk of our car, which is parked on a residential road. Using a stick, we slather peanut butter from a huge jar into each trap as bait.....»»
This mutant Venus flytrap mysteriously lost its ability to “count”
The mutant can no longer decode calcium signature that causes trap to shut quickly. Comparing stimulation of a Venus flytrap and the mutant DYSC. Credit: Ines Kreuzer, Rainer Hedrich, Soenke Scherzer.....»»

Camera-trap study provides photographic evidence of pumas" ecological impact
A camera-trap study of two ecosystems—one with pumas and one without—adds to scientists' understanding of the many ways apex predators influence the abundance, diversity and habits of other animals, including smaller carnivores......»»
Carnivorous oyster mushrooms can kill roundworms with “nerve gas in a lollipop”
Gas chromatography-mass spectrometry ID'd the culprit as the volatile ketone 3-octanone. Enlarge / Oyster mushrooms (Pleurotus ostreatus) serenely growing on a tree trunk in a forest. But nematodes beware! These oyster mushrooms.....»»
Angola"s peatlands trap carbon and clean the region"s water—how we mapped this newly-found landscape
Ask most people what they picture when thinking about natural "carbon sinks"—ecosystems that absorb and store greenhouse gases—and they'll probably describe a forest. Reforestation is a common feature of climate change plans......»»
