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.”

Lilies growing in the ground produce roots along their stem, and then little white bulblets, but I didn't expect they'd root except with soil around them.
Photomicrograph of a Dandelion stem cross section. This is my first attempt at histological specimen preparation. Next time I need to use a thinner layer of Meyer's Albumin as it took up some of the stain.
Bright field micrograph created using a Sony NEX 5N on a Nikon SM inverted microscope with a Zeiss 2.5X objective, 4X eyepiece and a Leica MICAS microscope adapter with a 2/3X reducer.
Fixed in FAA 48 hr. Dehydrated 70 % ETOH 95% ETOH 2X, 99% IPA 3X. Cleared in xylene 2X, Infiltrated with Paraplast 2X, mounted in Paraplast. Sectioned with a Spencer 820 microtome at 7 microns. Floated on a water drop on a Mayer's Albumin coated slide and dried. Cleared in Xylene 2X. Rehydrated 99% IPA, 95% ETOH. Stained with Aniline Blue IPA, fixed acid alcohol, stained Orange G. Dehydrated 95% ETOH, 99 % IPA 2X. Cleared in Xylene 2X. Mounted with Fisher Permount.
Threaded alloy cover is removed with a 6 mm. Hex Key tool (Allen Wrench in US) which also operates the expander and handlebar clamp bolts hidden within.

Wheat stem with pustules caused by stem rust (Puccinia graminis). These are dark reddish brown, contain masses of urediospores, and may occur on both sides of the leaves, on the stems, and on the spikes.

a tomato stem. so, like, i thought tomatoes were citrus since they have citric acid, but, like, i was apparently wrong.
October 10 2008 - I just recently heard it closed permanently. It makes me quite sad to hear that. Many of my best Sundays started here.

Urology focuses on the urinary tracts of males and females, and on the reproductive system of males. In men, the urinary system overlaps with the reproductive system, and in women the urinary tract opens into the vulva. In both sexes, the urinary and reproductive tracts are close together, and disorders of one often affect the other. Call us for more information>>>Dr. Todd malan

Finally a little progress after several weeks out on a mission project.. Had the RV parked on the bank of the Chesapeake Bay? A Hardship! NO BOAT! But got back and installed the stem reinforcement. Here is the additional wood reinforcemetn that backs up the bow.
Family STEM Night: The Physics of Sports.
Get with the Program is a nonprofit organization headquartered in Oberlin, Ohio, that promotes and reinforces literacy in science, technology, engineering, and mathematics (STEM) from preschool through 12th grade.

Stem rot caused by Helminthosporium sigmoideum ( Leptosphaeria salvinii or Magnaporthe salvinii
) (Photo 80) — Infection usually occurs near
the waterline, entering through wounds and injuries.
It starts as blackish, dark, irregular lesions on
the outer leaf sheath and gradually enlarges.
Eventually, the fungus penetrates into the culm
and weakens the stems and leads to lodging
(Photo 81).
Part of the image collection of the International Rice Research Institute (IRRI)
The Science, Technolgy Engineering Mathmatics (STEM) partnership had a Forum Event "Gathering Momentum" at the Henry Ford College, Loughborough University on Wed..In the picture are some of the guest speakers, from the left, Rick Hall, Sarah Hill, David Wilkinson, Geoffrey Taylor Henry Lau and Pat Morton
The image shows details of plants of Common Reed (Phragmites australis) growing above high water mark on a beach in Cornwall.
Rhizomes are horizontal underground stems. In the first image, spring tides have washed away the sand that originally covered the base of the plant and the rhizomes can be seen. These stems act as a food store as well as a means of vegetative reproduction.
In this image you can see that there is a constriction in the rhizome – a node – from which a leafy shoot and adventitious roots arise.
The section of rhizome is approximately 10 cm long.
