Imaging Ca2+ flux through individual ion channels by total internal reflection fluorescence microscopy (TIRFM).

Demuro A and Parker I. JGP 2005; 126(3):179-92


Images of the effects of membrane potential changes on Ca2+ waves.

Yao Y and Parker I. J.Physiology 1994; 476: 17-28


Confocal images of calicum puffs and waves in Xenopus oocyte.

Callamaras N and Parker I. Cell Calcium 1999; 26: 271-279



Images show intracellular Ca2+ signals evoked in a Xenopus oocyte by photorelease of inositol trisphosphate from a caged precursor. Each panel is a surface representation derived from a single image frame captured using a `home-made' video-rate confocal microscope. 

Marchant J and Parker I. Embo Journal 2001, 20: 65-76


Cover was created as an image of the local concentration of Ca2+ in an oocyte of Xenopus laevis induced by photolytically releasing caged inositol 1,4,5-triphosphate.


Stochastic view of lymphocyte motility and trafficking within the lymph node.

Cover illustration represents the motion of T (green) and B (red) cells at the edge of a folicle, and the images were accumulated sequentially in the four panels.

Cell writing: the series of sequential video frames (30s-1) shows liberation of intracellular calcium in a Xenopus oocyte in response to photorelease of inositol trisphosphate from a caged precursor. Ultraviolet photolysis light was focused onto the oocyte through a mask to form the characters "Ca2+", and the resulting localised liberation of calcium ions from intracellular stores was imaged using a Noran Odyssey confocal microscope to monitor fluorescence of the indicator dye calcium green-5N. The resolution of the characters is in part determined by the spacing between calcium stores in the oocyte which, at about 6um, is appreciably better than achieved by a 600 dpi laser printer.


EMBO Journal, October 2007

Cover photo shows a island in Lake Powell, newly exposed by the falling water level, and framed by sunset reflections of Gunsight Butte.

The image was selected from the annual EMBO photo contest, and was featured also in the 2008 EMBO callendar.

 


EMBO Journal, April 2008

Serenity - Winter sunset at the Kern Wildlife Refuge in the central valley of California.

The image was selected from the annual EMBO photo contest.

 


EMBO Journal, September 2008

Cover photo shows a sundog formed by refraction of hexagonal ice crystals in the stratosphere. The photograph was taken in Arches National Park, capturing a reflection in a small rainwater pool.

The image was selected from the annual EMBO photo contest.

 

 


EMBO Journal, December 2008

Cover photo shows a California brown pelican at take-off. The photograph was taken at Bolsa Chica reserve.

The image was selected from the annual EMBO photo contest.

 

 


EMBO Journal, April 2009

Cover photo shows two long-billed curlews on a misty morning at Morro Strand beach.

The image was selected from the annual EMBO photo contest.

 

 


EMBO Journal, April 2010

"Flying wing". One of the striking rock formations at Little Finland, Nevada.

The image was selected from the annual EMBO photo contest.

 

 


Cell, July 2010

Eukaryotic cells rely on aerobic mitochondrial metabolism to generate ATP. Here, Cárdenas et al. (pp. 270–283) demonstrate that constitutive low-level Ca2+ release through endoplasmic reticulum InsP3 receptor release channels (yellow flashes), in close proximity to mitochondria, is essential for mitochondria to produce sufficient ATP and to maintain normal cell bioenergetics.

EMBO Journal, September 2011

"Preying mantis in Antelope Canyon".

This slot canyon is a favorite subject of photographers aroound the world. The discovery of a preying mantis on a boulder provided the opportunity to capture a novel image of this cliched location, and gave a nice contrast of green against the orange/red rock.

The image was selected from the annual EMBO photo contest.

 

 


Nature Geoscience, September 2011

The badlands around Zabriskie Point in Death Valley illustrate an article in this issue.
