Fruit flies survived extreme 13g hypergravity that would crush most humans

ZME SCIENCE - For humans, a fruit fly weighs almost nothing. Yet when scientists made that tiny body feel four, seven, ten, and even thirteen times heavier than normal, it survived every time. At 13G, humans can only survive for a few minutes. In a new study, researchers at the University of California, Riverside, spun...

Scientists weaponize 'pine tree scent' to trick and kill insect pests without using toxins

EARTH.COM - Termites chew through the wooden framing of houses and cost property owners billions of dollars every year. Fixing this severe property damage usually requires pest control workers to pump homes full of highly toxic gases. Families have to pack up and evacuate their houses for several days during these extreme chemical treatments. We...

Fruit flies survive 13G hypergravity, show resilience in rapid-spin centrifuge

INTERESTING ENGINEERING - Humans can tolerate only brief bursts of extreme gravitational force. Fighter pilots train to endure high G-loads, but even they struggle beyond 9G. At higher levels, blood drains from the brain, causing blackout within seconds. Sustained exposure remains dangerous and poorly understood, especially during spaceflight and reentry. Now, new research from the...

Scientists exposed flies to crushing hypergravity. The results were unexpected.

GIZMODO - Pests are, well, pesky because they simply won’t go away. And in a terrifying turn of events, scientists found that the fruit fly—a super common kitchen pest—adapts and survives under crushing hypergravity. According to a study on the findings, published recently in the Journal of Experimental Biology, fruit flies initially show some bolstered...

Hawaiian forest birds are stealing each other’s twigs

POPULAR SCIENCE - Birds in Hawaii are stealing from each other, and this bird-on-bird crime even extends to members of the same species. It’s an example of kleptoparasitism, or when an animal steals things from another. Specifically, these colorful, winged kleptoparasites are pilferring nest-material, sometimes causing the demise of the depleted nest. Researchers documented this...

Composting can be wildly frustrating. Maggots to the rescue

LAIST - Do you hate composting as much as I do? Even though I know it has benefits for both my garden and the environment, I hate turning the pile and worrying about the right ratio of greens to browns and whether it’s too wet or too dry. And it’s always dispiriting to check for...

Scientists have discovered the bed bug’s greatest fear

GIZMODO - Despite their tiny size, bed bugs are perhaps the scariest thing a person can realistically encounter in their home. But what do these blood-sucking fiends fear most? The answer, recent research shows, is apparently water. Scientists at the University of California, Riverside, tracked how bed bugs behaved around water. The insects avoided wet...

Bed bugs fear water, and this could change how we fight them

EARTH.COM - Have you ever wondered if bed bugs are afraid of anything? These tiny blood-sucking insects cause stress in homes around the world. Once bed bugs enter a room, getting rid of them can feel almost impossible. But new research from the University of California, Riverside has revealed something surprising. Bed bugs fear water...

California researchers working to prevent screwworm infestation north of the border

NEWSNATION - During the late 1800s and well into the 1900s, the New World screwworm invaded the U.S., devastating livestock and requiring a decades-long eradication campaign. During that time, the fly could be found from California to Florida. Eventually, scientists discovered that by releasing sterile male flies into the air, they could all but eliminate...

Flesh-eating Screwworms are creeping closer to a comeback in the United States

SMITHSONIAN MAGAZINE - Roughly 60 years ago, the United States eradicated the New World screwworm, an insect that feeds on living tissue. But now, the flesh-eating creature appears to be creeping closer to a comeback. New World screwworm is the name given to the larval, or maggot, stage of the Cochliomyia hominivorax blowfly. Loosely translated...
