Manipulating the metabolic process in cells may compensate for defects that can shorten cell life UAlberta researchers are taking a closer look at how two metabolic pathways interact to increase the lifespan of cells with mitochondrial defects. Magnus Friis (PhD ’10) is the lead author of the study, which was published online on April 10 and will be published in the April 24 issue of Cell Reports. Mitochondria produce energy for cells through oxidative metabolism, but the process...

Layers Of Color Cells Form Guppy's Spots
2014-01-24 10:11:10

Public Library of Science Multiple pigment cell types create black, blue, orange spots of the guppy At least three pigment cell types from multiple layers of skin contribute to the color patterns of male guppies, according to a study published in PLOS ONE on January 22, 2014 by Verena Kottler from the Max Planck Institute for Developmental Biology and colleagues. Female guppies select their mate based on the size and number of colorful spots on a male's body and fins. Orange, blue,...

Female Squid Have Two Ways To Switch Color According To Study
2013-09-19 11:30:34

University of California - Santa Barbara The female common market squid –– AKA Doryteuthis opalescens –– may not be so common after all. Researchers at UC Santa Barbara have discovered that this glamorous cephalopod possesses a pair of stripes that can sparkle with rainbow iridescence. These flank a single stripe, which can go from complete transparency to bright white. This marks the first time that switchable white cells based on reflectins –– the proteins responsible for...

Squid Use 'Electric Skin' For Camouflage
2012-08-28 07:43:03

Watch the Video: Squid´s Remarkable Electric Skin Lee Rannals for redOrbit.com - Your Universe Online Squid and their relatives are notorious for being some of nature's best masters of disguise, but their trickery has, for the most part, remained a mystery until now. Scientists report that squid control their skin's iridescence through their nerves, manipulating the animal's spectrum of hues, as well as their speed of change. This research is the first time neutral control of...

Squid And Zebrafish Spark Camouflage Inspiration
2012-05-04 04:59:16

University of Bristol researchers have created artificial muscles that can be transformed to mimic the camouflaging abilities of squid and zebrafish. The team demonstrated two individual transforming mechanisms that they believe could be used in "smart clothing" to trigger camouflaging tricks similar to animals observed in the wild. "We have taken inspiration from nature's designs and exploited the same methods to turn our artificial muscles into striking visual effects,"  Jonathan...

Researchers from the University of Bristol have created artificial muscles that can be transformed at the flick of a switch to mimic the remarkable camouflaging abilities of organisms such as squid and zebrafish. They demonstrate two individual transforming mechanisms that they believe could be used in 'smart clothing' to trigger camouflaging tricks similar to those seen in nature. The study is published today, 2 May, in IOP Publishing's journal Bioinspiration and Biomimetics, and is...

Instant Camouflage Discovered In Two Cephalopods
2011-11-11 11:17:36

[ Watch the Video ] Scientists have discovered two deep ocean species of cephalopods, the octopus Japetella heathi and the squid Onychoteuthis banksii, that can go from transparent to opaque in the blink of an eye, a new study finds. This impressive camouflage swap, from both an octopus and a squid, is an adaptation that help keeps the species safe from different types of predators, Stephanie Pappas of LiveScience reports. The first predators that the cephalopods must be wary of are...

The intestinal epithelium consists of four main specialized cell lineages: absorptive enterocytes and three secretory cell types known as enteroendocrine, Paneth, and goblet cells. But a rare, fifth type of intestinal cell called tuft cells also exists. Defined by the thick brush of long microvilli that project from their apical surface, tuft cells are seen in several epithelial tissues, yet little is known about their function due to a lack of tuft cell"“specific markers. In the March...

Coral reefs support some of the most diverse ecosystems on the planet, yet they thrive in a marine desert. So how do reefs sustain their thriving populations? Marine biologist Fleur Van Duyl from the Royal Netherlands Institute for Sea Research is fascinated by the energy budgets that support coral reefs in this impoverished environment. According to van Duyl's former student, Jasper De Goeij, Halisarca caerulea sponges grow in the deep dark cavities beneath reefs, and 90% of their diet is...

UCSD researchers stretched cells in a workout chamber the size of a credit card to gain a better understanding of how repetitive stretching of endothelial cells that line arteries can make them healthy and resistant to vascular diseases. Bioengineering researchers at UCSD's Jacobs School of Engineering will report in the Nov. 1 issue of Proceedings of the National Academy of Sciences (PNAS) that arterial endothelial cells subjected to repeated stretching (10 percent of their length, 60 times...

Paneth Cells
2012-07-01 19:03:07

Paneth Cells are one of four principal cell types found in the epithelium of the small intestine; the other three are the goblet cell, enterocyte, and enteroendocrine cell. Paneth cells may also be found in the cecum and appendix, although sporadically. These cells are identifiable microscopically by their location just below the intestinal stem cells in the intestinal glands. and the large eosinophilic refractile granules that occupy most of their cytoplasm. These granules consist of...
