Commercially Available Hand Creams – Sample Preparation for Cryo-SEM

http://www.leica-microsystems.com/science-lab/commercially-available-hand-creams-sample-preparation-for-cryo-sem/

Application Note for Leica EM HPM100 – Hand creams having different water contents were applied into the 100 μm cavities of two 3 mm type A sample carriers which were then closed cream sides inwards. The sample assembly was high pressure frozen with a Leica EM HPM100 and moved to a cooled Leica EM VCT100 loading station.

Unsafe conditions, reduce speed: DJI Inspire 2 not as fast as originally announced

http://www.imaging-resource.com/news/2016/11/30/unsafe-conditions-reduce-speed-dji-inspire-2-not-as-fast-as-announced

 

 

In mid-November, DJI announced their new DJI Inspire 2 drone, which was advertised to be faster, lighter and offering better imaging capabilities. All of that should still hold true when the Inspire 2 starts shipping in December, but DJI has announced that the top speed of the Inspire 2 will not be as high as previously disclosed. The original announcement declared the top speed of the Inspire 2 to be 67 miles per hour, but the new top speed is listed at 58 mph. Further, the new drone will take five seconds to reach 50 mph rather…

Olympus E-M1 Mark II Field Test Part II: Putting continuous autofocus to the test and more

http://www.imaging-resource.com/news/2016/11/29/olympus-e-m1-mark-ii-field-test-part-ii

 

 

When I first got acquainted with the new Olympus E-M1 Mark II, it was up in Iceland, an absolutely stunning place filled with awe-inspiring landscapes anywhere you turned as well as some rather harsh weather conditions. I was able to get a good sense for the E-M1 II's overall image quality performance and its build quality, but I wasn't really afforded an opportunity to truly test out one of the camera's major upgrades: continuous autofocus.

Now, in my just-published Field Test Part II on the Olympus E-M1 II, I put a major focus…

Multispectral Phloem-Mobile Probes: Properties and Applications

http://www.leica-microsystems.com/science-lab/multispectral-phloem-mobile-probes-properties-and-applications/

Using Arabidopsis (Arabidopsis thaliana) seedlings, we identified a range of small fluorescent probes that entered the translocation stream and were unloaded at the root tip. These probes had absorbance/emission maxima ranging from 367/454 to 546/576 nm and represent a versatile toolbox for studying phloem transport. Of the probes that we tested, naturally occurring fluorescent coumarin glucosides (esculin and fraxin) were phloem loaded and transported in oocytes by the sucrose transporter, AtSUC2. Arabidopsis plants in which AtSUC2 was replaced with barley (Hordeum vulgare) sucrose transporter (HvSUT1), which does not transport esculin in oocytes, failed to load esculin into the phloem.

Preserving the past: Edward S. Curtis and his storied portraits of Native Americans

http://www.imaging-resource.com/news/2016/11/29/preserving-the-past-edward-s.-curtis-and-his-storied-portraits

 

 

November is National American Indian Heritage Month, and as such it seems particularly appropriate to take a moment to look at the legacy of American photographer Edward S. Curtis.

Edward S. Curtis was an American photographer in the late 19th and early 20th centuries. His love affair with photography began shortly after he left school in the sixth grade when Curtis built his own camera. At 17, he became an apprentice photographer. Two years later, he and his family moved to Seattle and Curtis became a partner in a photographic…

Best lenses for astrophotography: The ultimate guide from Lonely Speck

http://www.imaging-resource.com/news/2016/11/29/best-lenses-for-astrophotography-the-ultimate-guide-from-lonely-speck

 

 

Astrophotography is a particularly demanding genre of photography that emphasizes a distinct set of qualities and characteristics of lenses. Qualities such as autofocus speeds (or being capable of autofocus at all) and sharpness when stopped down become less important, whereas characteristics such as having a focus scale and the amount comatic aberration are given utmost importance. This can make shopping for a lens for astrophotography difficult, as traditional lens reviews may not hit on the factors important to star-gazing…
