San Rafael Swell

Image
San Rafael Swell is a vast area of almost 2,000 square miles of uplifted layered rocks eroded into canyons, mesa, buttes, rock towers and natural arches. It’s Bureau of Land Management real estate bisected by Interstate 70, which provides much of the access to the area. As you leave Green River, Utah, westbound on I-70, a sign advises “No Services for the Next 106 Miles.” You’ll see a similar sign if you’re traveling eastbound on I-70 from the San Rafael Swell. A maze of gravel roads maintained by Emery County is suitable for automobile and light truck travel, though a few roads in the area require a four-wheel-drive vehicle. The San Rafael Swell is ringed by the towns of Price, Green River, Hanksville, Caineville, Emery, Castle Dale, Huntington and Cleveland. In addition to I-70, other roads that circumnavigate the Swell include Utah State Route 10 on the west side between Price and I-70, U.S. Route 6 connecting Price and Green River on the northeast side of the Swell, and Utah Stat...

Shooting In Tempestuous Weather

Image
“Clear skies, temps in the low 70s, no wind and cloudless skies for the next two days,” states the weather person on the local news channel. “Oh well,” I mutter out loud, “more of the same mundane conditions with no mood or drama.” No shots of saturated, wind-blown autumn leaves blanketing a curved country dirt road while radiating red, yellow and orange. No images of dramatic thunderheads entering the skyline above the mountain lake. No moody fog coursing its way through the stand of redwoods and ferns. No possibility to get reflected city lights in a puddle with streaks of car lights mirrored on drenched streets. I really wanted to use the red umbrella I purchased while I release the shutter with my remote trigger to capture a photo of me walking down that beautiful S-curved road. I’m being a bit cynical, but there’s truth and validity in the above words. I fully concede that first light as the sun crests the horizon and last light right before the sun goes to sleep provide gorgeou...

Photo Of The Day By David Connel

Today’s Photo Of The Day is “Bugaboo Splendor” by David Connel. Location: Bugaboo Provincial Park, British Columbia. “My climbing buddy and I climbed Pigeon Spire in Bugaboo Provincial Park in British Columbia, Canada,” explains Connel. “I debated about bringing my DSLR camera, not wanting to haul the extra weight up the peak. Since I did bring the camera with me, I spent the whole climb looking for that unique perspective to capture the drama of climbing and the rugged beauty of the mountains. When we got to a saddle, I knew immediately that this was the image I wanted. If you look very closely, you can see my climbing buddy in a red jacket on the ridge. I’m so glad that I carried the extra weight.” Photo of the Day is chosen from various OP galleries, including Assignments ,  Galleries  and the  OP Contests .

Image
Nature, Published online: 26 August 2020; doi:10.1038/s41586-020-2648-3 In a study performed in Schizosaccharomyces pombe, ‘closed mitosis’ is shown to occur via local disassembly of the nuclear envelope within the narrow bridge connecting segregating daughter nuclei, and a key role is identified for Les1, which restricts nuclear envelope breakdown to the bridge.
