A parasitic fungus that controls the behaviour of fruit flies has, for the first time, been studied in the lab.
In a fascinating preprint posted on Biorxiv, researchers Carolyn Elya et al. report how they discovered the pathogen in the wild near Berkeley, California. The fungus belongs to the species Entomophthora muscae, which is already known to prey on various species of wild flies. But Elya et al. found a way to infect laboratory flies with the disease, thus allowing them to study the fungus ...read more

Mind-controlling parasites are the stuff of nightmares and blockbuster horror movies, yet organisms that turn normally sensible creatures into zombies are all too real. Most of the microbes and fungi that do this are restricted to the insect world, luckily, though those cases are gruesome enough.
Ants with fungal spores growing from their heads, cockroaches eaten from the inside by parasitic wasp larva, fish driven to suicide-by-bird &m ...read more
This schlieren image shows an Air Force Test Pilot School T-38 in a transonic state, meaning the aircraft is transitioning from a subsonic speed to supersonic. Above and beneath the aircraft, shockwaves are seen starting to form. (Credit: NASA)
NASA wants to make sonic booms a little less…boom-y.
When a jet breaks the sound barrier, it generates shockwaves that are eventually heard—and felt—on the ground as sonic booms. The boisterous nature of supersonic flight is one of th ...read more

Poinsettias are a holiday icon. Their crimson colors are so commonplace this time of year that they practically blend into the background. And once the holidays are over, they’ll disappear like so many Christmas trees.
But these seemingly boring flowers actually hide a fascinating history. Poinsettias owe their holiday prevalence to some weird quirks of evolution — and one clever So ...read more
Space may look vast, but it’s actually pretty crowded near Earth.
As of a couple of years ago, more than 1,300 active satellites orbited Earth, in addition to tens of thousands of dead satellites, discarded rockets and other bits and pieces that have accumulated in space in the 60 years since Sputnik, ranging in size from softballs to school buses. When we turn on a new radar in a few years that can see even smaller pieces, we are going to see millions of them.
And it’s going to con ...read more
