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.....»»
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......»»
Climate change is coming for the Jersey Shore, retiring coastal expert warns
On a dock overlooking a coil of Nacote Creek in Atlantic County, New Jersey, earlier this month, Stewart Farrell, director of Stockton University's Coastal Research Center, gave an impromptu master class on barrier islands, ancient geology, crab trap.....»»
A husband-and-wife team solve the mystery of how worms develop their gut
Were it not for the COVID-19 pandemic, an important discovery about the development of nematodes—elongated cylindrical worms—might not have been made......»»

The Professional Repairer Trap: We are all Geniuses. Don’t let the corporations tell you otherwise
For years, my organization, U.S. PIRG (Public Interest Research Group), has been campaigning with iFixit,Repair.org, and a plucky team of repair shops, makers, and hackers to pass laws that guarantee access to what people need to fix modern giz.....»»
How community-engaged archaeology can be a pathway to reconciliation
We are standing in a circle on an expansive beach in front of an ancient rock-walled fish-trap—one of many archaeological sites on the small island of Xwe'etay (Lasqueti) in the Salish Sea between Vancouver Island and the British Columbian mainland.....»»
Climate Questions: How does carbon dioxide trap heat?
That carbon dioxide and other greenhouse gases trap heat is something scientists have known about for more than a 150 years. The underlying concept behind climate change is simple enough that school children can replicate the chemistry and physics an.....»»
How advanced optical tweezers revolutionized cell manipulation
Optical tweezers (OTs), also known as optical traps, are highly focused laser beams that can be used to trap and manipulate microscopic objects with a noncontact force. Employed in a wide range of nano and micro-scale operations, OTs have become part.....»»
New technique to trap soundwaves and light on a chip in large-scale circuits
In recent decades, chips and electronic devices have become exponentially smaller and faster. Engineers have nearly reached the limits of traditional electronics and are now in the process of transitioning from electronics to photonics, using light i.....»»

Researchers identify genes potentially responsible for sugarcane"s resistance to pests, cold and drought
A study conducted at the State University of Campinas (UNICAMP) in Brazil has identified orphan genes in wild sugarcane (Saccharum spontaneum), a species with exceptional resistance to biotic stresses such as nematodes, fungi, bacteria and other pest.....»»
Racing to the roots: Soil moisture impacts the speed of nematodes
Did you know one of the oldest life forms on Earth can be found in your backyard? Soil nematodes have been thriving in habitats around the world for at least 400 million years. Even though they are only 1/500th of an inch wide and 1/20th of an inch l.....»»
New insight into selecting appropriate primers and databases when sequencing soil nematode DNA
Soil nematodes represent a major component of soil communities in terrestrial ecosystems, and play an important role in regulating nutrient cycling and soil health. High-throughput sequencing technology is increasingly used in the study of nematode b.....»»
