Is it time for a sustainable pet movement?

by Southern Fried Scientist in Southern Fried Science

The world is rapidly approaching 7 billion people and the challenges of food supply, security, and sustainability will, along with climate change, be the defining issues of the 21st century. While the issues of the wealthiest nations revolve around the quality of our food, the environmental impact or our farming practices, and the value we place [...]... Read more »

The genetics of renal cell carcinoma

by Joana Guedes in BHD Research Blog

As mentioned in the blog last week, high-throughput DNA sequencing is helping to identify novel mutations related to a number of different genetic disorders. A recent example of this can be seen in a study by Varela et al. (2011), … Continue reading →... Read more »

Friday Weird Science: The measure of a man, not quite what you’d think.

by Scicurious in Neurotic Physiology

Of COURSE this awesome paper would blow up the internets on a Monday, and of course, as you know, Sci is never funny on Mondays. She is only funny on Fridays. Should you ever find Sci funny on any other day of the week, you are delusional. But now I have the paper, and I’d [...]... Read more »

Australasian big-eared bats, and how to (perhaps) single-handedly wipe out an entire species, 1890s-style (vesper bats part X)

by Darren Naish in Tetrapod Zoology

About 12 species of big-eared Australasian bats are known as the, err, Australian big-eared bats and New Guinean bats. More formally, they are the Nyctophilus species. They're also known from some of the islands that surround New Guinea (like the Lesser Sundas), and also from New Caledonia (an endemic New Caledonian species, N. nebulosus, was named in 2002). Their presence has also been claimed for Fiji, but the evidence for this (based on specimens stored at the Natural History Museum in Lo........ Read more »

Sex and mosquitoes – transmitting the Zika virus

by Captain Skellett in A Schooner of Science

When Brian Foy returned home to America from a field trip in Senegal, Africa, he didn’t know he was infected with the mosquito spread Zika virus. But just a few days later he was sick with extreme fatigue and joint pain, and so was his wife Chilson. A new study coauthored by the pair and [...]... Read more »

Beyond the Bacterial Microcompartment

by Merry Youle in Small Things Considered

Bacterial microcompartments were a great innovation. As Alan Derman explained, these protein-bounded structures assist with diverse metabolic processes by housing the requisite enzymes along with their substrates, sequestering potentially toxic intermediates, and allowing the products to exit. But the story does not end there. Enter the nanocompartment.

These are the simplest variation known so far on the theme of bacterial compartments. Like the micro version, these nano structures are thin........ Read more »

by Erin Campbell in HighMag Blog

What do you have in common with a worm? A lot, and you should be thankful! The worm C. elegans is used as a model system that allows researchers to learn an amazing amount about the genetic pathways and development in many systems, including our own. Thankfully for HighMag, the worms are quite photogenic too. Our germ line is the line of cells that are responsible for passing on our genetic material to the next generation. The germline is composed of gametes (eggs and sperm), as well as the........ Read more »

A new view on eye development

by Eva Amsen in the Node

How do you make an eye? In the developing embryo, this process begins with the formation of the optic vesicle from the neural tube. This optic vesicle then invaginates to form an optic cup, which in turn develops into the outer pigmented layer of the retina and the inner neurosensory layer. Normally, this all takes [...]...

When girls are better (only sometimes)

by Neil Losin in Day's Edge

Remember the Gouldian Finch? I wrote about it a few months ago. Sarah Pryke, a behavioral ecologist at Macquarie University in Sydney, Australia has conducted some amazing research showing that female Gouldian Finches can control the sex ratio of their broods. Now, there’s no denying that Gouldian finches are weird; males and females come in [...]... Read more »

Robust jaws and a (sometimes) 'greenish' pelt: house bats (vesper bats part IX)

by Darren Naish in Tetrapod Zoology

Hey, if anyone out there is bored with the bats, just gimme a shout. If you're loving it, say so, and urge me to post more - there's still a lot to come! Yes, welcome once again to the vesper bat series: for previous installments see the list of links at the bottom of this article. We continue our trek through vesper bat diversity with another of the clades often regarded as a 'tribe' within the vesper bat 'subfamily' Vespertilioninae: the house bats or yellow bats, conventionally grouped to........

Fascinating jumping spiders

by Africa Gomez in BugBlog

We had a very warm day today - for April - the sun hit the brick walls and this is something that brings jumping spiders out. I spot one on the wall, quite high up, she moves in a typical jerkily fashion on to a wooden plank and I take a few shots with my arms outstretched and a poor view of the LCD display, but I am happy when manage a few focused front shots (above). I think this is Salticus cingulatus, a close relative of the zebra jumping spider, Salticus scenicus. Jumping spiders, or saltic........ Read more »

She’s having a baby! I think?! A promising new technique for pregnancy sampling in wild cetaceans…

by Dr. Carin Bondar in Dr. Carin Bondar - Biologist With a Twist

Assessment of the reproductive status of wild cetaceans (dolphins, whales and porpoises) is difficult and therefore not often practiced or accomplished.  Fecal and/or blood samples are effective techniques for use with captive and stranded individuals; however, these kinds of fluids aren’t so easy to obtain from specimens in their natural habitat.  Researchers primarily rely on [...]...

Without plaits there is an explosion

by Marisa Alonso Nuñez in Science Box

As I've mentioned in my previous post Why using yeast for research?  one of  the applications of yeast for research is in the field of discovering new antifungal drugs. In order to do this the studies are focused on  the yeast cell wall. This cell wall is present in yeast and fungi but not in human cells.So, to continue with my posts about basic research with yeast, today I'm going to write about a study done by some scientists I used to work with during my PhD in Salamanca.This study is abou........

Electrifying deterrents: wolves and fladry

by DeLene Beeland in Wild Muse

Fladry has proved to be an interesting and rather low-tech tool to ward wolves away from domestic livestock in certain conditions. It consists of red flags or pennants attached to a piece of twine or thin rope at regular intervals (about 18 inches or so) and strung around a livestock corral or pen. Like all [...]... Read more »

Tawny mining bee nesting aggregations

by Africa Gomez in BugBlog

I have been posting on the Tawny Mining Bees, Andrena fulva, recently. I have been watching suitable nesting sites for signs of activity and today I came across many nests located in groups in several grassy areas. It was a bit windy and the female bees often missed their nests when landing. Instead of walking the short distance, they would fly again, carry out what looked like a positioning flight, and landed on top of their nest mound and got inside. Some females seemed to be looking for ........
