A single layered, cutinized epidermis overlies an interior composed entirely of cortical tissues. Within the cortex a few layers of sclerenchyma can be seen just beneath the epidermis. Below that lies a cortical region composed entirely of loosely packed thin walled parenchyma and intercellular spaces.
There is no apparent stele, rather the vascular bundles are scattered throughout the cortex with numerous small bundles crowded nearly the periphery of the stem and fewer larger bundles towards the center of the stem.
The vascular bundles are closed and collateral. Xylem is oriented towards the center of the stem and small amounts phloem to the outside. Cambium is lacking preventing secondary growth. In mature vascular bundles, the earliest protoxylem may break down to produce a large protoxylem cavity. The vascular bundles are wrapped in a bundle sheath of thick walled supportive sclerenchyma cells.
Unlike most grasses Zea stems are not hollow at the center.

This little program looks for photos on flickr by a given search word. Afterwards, the colors of the photos are analyzed. The color itself gets detected and how often each color is found. This data is the foundation of every stem. Each segment represents one color of the photo, the diameter shows the quantity. The cell resolution in all segments is based on the brightness of the color.
My goal was to try a more abstract approach to shooting flowers. These flower stems reminded me of match heads on fire.

The nīkau (Rhopalostylis sapida) is a palm tree endemic to New Zealand, and the only palm native to New Zealand.

Osteochondroretricular stem cells (red) are a newly identified type of bone stem cell that appears to be vital to skeletal development. Research on these stem cells may lead to treatments for osteoarthritis, osteoporosis and fractures.

NIH scientists showed how ancient retroviral genes, or “junk DNA”, may play a role in helping stem cells decide to become neurons.
The image is a picture of stem cells in a petri dish. The blue dots represent cell nuclei. Green dots represent HERV-K, HML-2 viral envelope proteins encoded by “junk DNA” while red dots represent the immune cell protein CD98HC. Interactions between the two proteins produced a yellow color. The study suggests that these interactions restrain stem cells from becoming neurons and that turning off HERV-K, HML-2 activity frees them.

Late Friday night, 40 high school girls arrived at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, for a STEM-themed sleepover, ready to learn about careers in Science, technology, engineering and math. The educational event offered young women a chance to meet working female scientists and to discover opportunities for women in STEM-related professions.
The teens kicked off the third annual STEM Girls Night In with an astronaut Q&A, talks from female scientists across disciplines and a collection of hands-on activities. The night culminated in a three-hour Mars rover competition and concluded with a late-night showing of “Hidden Figures.”

This was a commission to create a stem for an existing metal flower sculpture. A fun project! The final size is 4 feet x 7 feet. Glass and tile mosaic on wediboard, installed on stucco.

Bird exhibit at the Science, Technology, Engineering and Math (STEM) Night at Lee Elementary, Manhattan, Kansas.
A wee close up of stems that were in a glass on our breakfast table. I think it looks quite cool. It's only about 2-3" wide.
A rare Routens stem, un-atached to a frame . I really like the aesthetic of these stems, with the pointed top curl, and the tapered handlebar clamp., Integrated bell mount, very functional.
just gorgeous.
I'd love one for my own Routens!!
Hand Appliqué Stems.. the cheats way.
1. Cut bias strips 1½in wide. (Stem will finish approx ½in wide)
2. Fold your strip in half lengthways and lightly press.
3. Pin the strip along the stem path easing the curves, bear in mind that the stem will finally lay to the left of the machined line.
4. Machine (or hand) stitch into place using a ¼in seam allowance, see diagram.
5. Ease the folded edge over to cover the raw edges and slip stitch into place by hand.
6. If you want a finished end then leave the last ¼in unstiched and turn under to finish neatly, the other end should be covered by a flower!
No cables in this shot. The integrated stem eliminates the hanger and flex from said hanger to calm chatter. An elegant innovation.
Powdercoated in a matte black. Amazed at how well it matched the anodizing on the faceplate. Good travels little stem. www.bantambicycles.com
NASA's Goddard Space Flight Center, in partnership with SAIC and Bowie State University, hosted the third Sustaining Women in STEM roundtable, featuring some of the nation's leading STEM trailblazers, on Nov. 7, 2019.
In an era when the workplace is shifting toward the promise of innovation and creativity for future generations, diversity must be a critical component of success. Nowhere is this more vital than in STEM fields, where women are still underrepresented.
The event featured STEM leaders who have demonstrated success in creating environments that encourage and advance women in STEM careers. The day included dynamic morning presentations, enlightening panel discussions, candid question-and-answer dialogues and afternoon breakout sessions.

Late Friday night, almost 50 students from Maryland and Virginia arrived at NASA's Goddard Space Flight Center in Greenbelt, Maryland, for a STEM-themed sleepover, ready to learn about careers in science, technology, engineering and math.
The educational event, which follows the success of our Girls Night In held in November, offered young men a chance to meet working scientists and engineers and to discover opportunities in STEM-related professions. In addition to meeting NASA scientists and engineers, students also met Chris Scolese (Director of Goddard Space Flight Center), Clayton Turner (Deputy Director, Langley Research Center), and former NASA Astronaut, Fred Gregory.
