Flyfocals: Vision and Vectors Help Hunting Robber Flies

by Melissa Chernick in Science Storiented

Image credit: Thomas ShahanRobber flies (Asilidae family) are not your typical house flies. They are small, predatory insects that feed on a vast array of other arthropods. While they are small in size (10 times smaller than a dragonfly), these guys are serious hunters. For example, Mallophora omboides is known as the “Florida bee killer” for its taste for honey bees. Other robber flies hunt down wasps, dragonflies, spiders, or grasshoppers, just to name a few. Perhaps almost as impressive a........ Read more »

Thiaminases poison animals by destroying an essential vitamin

by Rosin Cerate in Rosin Cerate

A fundamental part of being alive is continually building up and breaking down organic molecules. Some molecules can only be constructed or torn down by a select group of living things, which can make it interesting for everyone else. For example, only bacteria and archaea can synthesize vitamin B12, so we have to get it through our diet or by having it administered as a drug.... Read more »

Falling with Style: Controlled Gliding in Spiders

by Melissa Chernick in Science Storiented

Sometimes I read a paper because the methods catch my eye. I can just imagine some scientists sitting around a table with a beer and saying, “I wonder what would happen if we just dropped a bunch of spiders from the tops of trees.” An article published online yesterday did just that.Barro Colorado Island is a man-made island is located in Gatun Lake, created by filling of the Panama Canal. It is covered in tropical rainforests, and its inhabitants have been studied extensively. It would be a........ Read more »

Mutualism a.k.a Caterpillars Drugging Ants To Do Their Bidding

by Melissa Chernick in Science Storiented

The manuscript is done! Submitted! Summer interns are finished. Boot up Normal Life Mode, please. Recommence blogging. So many good papers have come out during my hiatus. Where to start…where to start…If you have read this blog for any amount of time then you will come across by fascination with ant manipulation, particularly zombification. This is why my cursor stopped over a new paper in Current Biology about caterpillars manipulating ants to do their bidding. Let’s start with mutualism......... Read more »

Not So Simple: Social Evolution in Silk-Weaving Ants

by Melissa Chernick in Science Storiented

Silk weaving ants. That in and of itself is really neat. Then you see this picture of Polyrhachis shattuck...I mean, look at her! How many cool points can one animal rack up? A new study in Behavioral Ecology and Sociobiology takes a look at these arboreal nesting and silk-weaving ants.Let's begin with sociality. It is one of those subjects in biology that is considered its own discipline. When you think of social animals you probably think of herds of mammals or maybe schools of ........ Read more »

Treating school uniforms to reduce dengue: the Finances

by Yao-Hua Law in TORCH

 [A shorter version of this article first appeared on SciDev.Net] Scientists working to reduce dengue among school children in Thailand are testing something new: insecticide-treated school uniforms. A recent model published in PLoS One suggests that this intervention can be economically attractive in the context of Thailand. Using data from dengue studies in Thailand, the […]... Read more »

The Charge of the Crazy Ant: Chemical Warfare Between Invading Species

by Melissa Chernick in Science Storiented

I’ll be the first to admit that I've been a little blog-negligent lately. Even when all of the ice and snow we've gotten here on the East Coast forced me to stay inside I just binge watched shows on Netflix instead. I’m not sure what brought me out of my procrastination funk and compelled me to do a little reading and writing. If you've been following the Facebook page then you've been getting a lot of yummy sciency tidbits, but it’s time for me to get back on the hard science wagon. I thi........ Read more »

Pinpointing the Pollen: Honeybees and a Host Jumping Virus

by Melissa Chernick in Science Storiented

Lately I've been revisiting some of my past topics and continuing the story with new research. Such is the case today. A relatively popular post of mine from 2010 called The Buzz on the Bees described a study from that year by Jerry Bromenshenk et al. investigating Colony Collapse Disorder (CCD). CCD describes the mysterious, sudden and serious die-off seen honeybee (Apis mellifera) colonies across the U.S. It is characterized by sudden colony death with a lack of adult bees in front of the........

A master-class in bizarre biology: itchy, incestuous, parasitic mites with adult offspring

by Chris Buddle in Expiscor

Pyemotes mites are parasitic on many insects, some of which are themselves economically important. After hanging onto their hosts, feeding on their haemolymph, and being good little parasites, females become engorged and have significant abdominal swelling. The eggs hatch in the female ovaries and the immatures develop develop inside their mothers, hatching as adults. When they emerge from their mothers, males swarm around the area where emergence is occurring, waiting for adult females to come ........ Read more »

Dung Beetles and Ball-Rolling: Star Light, Star Bright

by Melissa Chernick in Science Storiented

Lately, it seems that poo is a popular topic in science news sections, and the dung beetle seems to be up front and center. I suppose that, if you are a dung beetle, you've solved all sorts of poo-related problems. If you recall the dung beetles and ball-cooling post from November, you will remember that these insects use their dung balls to help cool off their feet on the blazing hot African sands. But what if you are a beetle that works at night? You can chuck out the hot feet problem and worr........ Read more »
