Meet the Volunteers Who Have ‘Donated Their Bodies to Science’

by Gail Peterkin, HMNS Volunteer

“Donate your body to science — volunteer at the Houston Museum of Natural Science!” Or so the tagline goes. Apparently, some volunteers have interpreted the phrase quite literally, and a number of volunteers have spent many years, if not decades, as HMNS volunteers. HMNS currently has 610 active volunteers at all three of our campuses — Hermann Park, Sugar Land and the George Observatory. Collectively, volunteers gave 41,783 hours of service in 2015. That’s a lot of hours! Volunteers contribute to the museum in a variety of ways. Although the vast majority are docents who interact with and educate visitors of all ages about the museum’s exhibits and items on display, others work behind the scenes with the museum staff, and a very select few, with special knowledge or expertise, work directly with museum curators.

Sandy Wilkins

Sandy Wilkens began volunteering at the museum during the 1982-1983 school year, when her daughter was in second grade. With a degree in education and a teaching certification, she found a niche at the inception of the Early Investigations program, a science education program for younger children. She recalls sitting on the floor around a teepee, telling inquisitive K-2 students about life on the Plains. Sandy likes to use everyday things to give kids a sense of perspective. For example, she points out that a child’s foot is about the same length as a T. rex tooth! Sandy and her family donated a corn snake named Houdini to the museum. An escape artist like his namesake, Houdini was known for vanishing from his tank. Helpful hint: To capture an escaped snake in a classroom, set up a small, sealed container full of mice (i.e., dinner) on the floor. Chances are you will find the snake wrapped around the container within the next day or two! Most recently, Sandy has coordinated the annual staff appreciation luncheon, given by volunteers to thank museum staff for their support.

Mary Briscoe preparing for a Guild luncheon.

Mary Brisco, a retired pharmacist, became a volunteer in 1987 to further her interest in science. Over the years, she has volunteered in almost all of the permanent exhibit halls, although she admits that the Cullen Hall of Gems and Minerals is a personal favorite. Mary likes to tell visitors about the mesolite with fluorapophyllite specimen. Extremely fragile, it traveled by air from India on a first-class ticket, packed in powdered soap for protection! Mary has served in many roles in the Volunteer Guild, including a term as Guild President. Mary’s most memorable museum experience was winning a raffle for a gold-and-diamond necklace and earring set at one of the Galas! Nowadays, Mary is enjoying a change of pace, working in the Cockrell Butterfly Center’s greenhouse on the seventh floor of the parking garage.

Elaine Swank with HMNS President Joel Bartsch.

Elaine Swank came to HMNS in September 1988, when HMNS President Joel Bartsch was a museum security guard! They became friends, and she remembers when he returned to HMNS as Curator of Gems and Minerals. Elaine especially enjoys school tours, and she continues to work regularly with Houston fourth graders through the HISD/HMNS Program. Although she has experience in all the permanent halls, she usually takes the kids to the Hall of the Americas, where she tells them what to do if they discover an archaeological artifact, and then brings them to the Morian Hall of Paleontology. She always reminds the kids to look up, to see the Quetzalcoatlus from Big Bend National Park in Texas flying overhead! Elaine is well known for carrying an artificial rose, to keep her school groups together.

Crafty Inda Immega.

Inda and Neal Immega are well known to frequent museum visitors. Inda and Neal are both geology Ph.D.s who worked in the oil and gas industry. Inda, a mineralogist, began consistently volunteering around 1996. She spends much of her time in Gems and Minerals, but also enjoys the challenges posed by special exhibits — here today and gone tomorrow. She claims she could easily spend a lifetime among the exquisite pieces in Fabergé: From a Snowflake to an Iceberg. Inda is popular with families and young visitors — she organizes and assembles kids’ crafts and activities for Members’ Nights and other special events. Her most memorable question was when an adult visitor asked about Titanic: The Artifact Exhibition: “Is the real ship in there?” Uhh, no, check the bottom of the North Atlantic … Of course, Inda takes all questions seriously and responded politely!

Docent training with Neal Immega.

Neal became a regular volunteer after retiring from Shell Oil in 1999. A paleontologist by training, he was thrilled to return to the world of paleontology. Neal says simply, “Paleo has always been my home.” He conducts tours, trains other museum docents, and provides specimens and repairs for the touch carts in Paleo, the Wiess Energy Hall, and for special exhibits like Amber Secrets: Feathers from the Age of Dinosaurs. Neal also works on special projects in paleontology. He curated the Zuhl petrified wood collection, which entailed working closely with Mr. Zuhl; has written labels for some special exhibits; and helps out with “orphan exhibits,” such as repairing and maintaining the steam engine on the lower level. Neal excels in artifact reproduction (fondly called “Nealifacts”), and he is particularly proud of the copper chisel and Egyptian-style wooden hammer he produced for one of the touch carts in the Hall of Ancient Egypt.

Neal and Inda Immega.

The Immegas both came to the museum at the urging of Irene Offeman, who was then the Curator of Paleontology. She said the museum needed more volunteers with formal geological and paleontological backgrounds, and the rest is history! Both Inda and Neal have joined HMNS and Curator of Paleontology Dr. Robert T. “Bob” Bakker at the museum’s Permian excavations in Seymour, Texas, and Inda recalls going on a “Dipsy the Diplodocus” trip to visit the original dinosaur quarry in Wyoming. They also got a close-up peek at the scaly skin of Leonardo, a Brachylophosaurus dinosaur mummy.

Malacology volunteers, from left: Barbara McClintock, Associate Curator of Malacology Tina Petway, Lucy Clampit, Jim Lacey, and Rachel Zelko.

The intrepid team of malacology volunteers deserves special mention. They have convened regularly for as long as most museum staff can remember! In fact, two malacology volunteers, Barbara McClintock and Jim Lacey, preceded the arrival of Associate Curator of Malacology Tina Petway! Barbara, a retired biology teacher, has been involved with HMNS for 64 years. When her children were small, she drove them up from Baytown to attend museum programs. When she retired from teaching in 1995 or 1996, her daughter Margaret (also a volunteer) told her to investigate volunteer opportunities at the museum. Barbara found a home in malacology and has never worked anywhere else — although she admits to a secret fondness for Gems and Minerals, too. Jim, a retired geology Ph.D., originally wanted to work on paleontological specimens. When he was told there were no paleo openings available, he switched to malacology and has remained there since 1998.

Colonel Currie’s Epitonium — see if you can find it in Cabinet of Curiosities!

Tina Petway came to the museum as a volunteer under former Curator John Wise, who relied on her shell identifications; Tina has a photographic memory for shells. A former schoolteacher, Tina has been a member of the Houston Conchology Society since age 12. Tina recruited the newest members of the malacology team: Lucy Clampit, a retired librarian and longtime member of the Houston Conchology Society, in 2005, and Rachel Zelko, the “baby” of the group who joined in 2015. While they don’t interact directly with the public, and work “behind the scenes” at the museum’s collections facility, the malacology group has established close personal relationships based on their shared love of shells and good food!

The group meets every Thursday, and usually more often. Rachel, for example, often comes in three or four times a week. They work on new collections—checking the data on incoming specimens, cataloging specimens, verifying identifications and the like. They have been very busy lately. Over the past several years, more than 20,000 specimens were added to the scientific malacology collection — a collection that is worldwide in scope and becoming one of the best in the world by reputation. An exciting discovery in one of the new collections included some shells collected by Colonel Edward Currie, who died in the Battle of Waterloo in 1815 — along with their original handwritten labels! These Epitonium shells are now on view in the museum’s Cabinet of Curiosities exhibit.

Malacology volunteer Barbara McClintock on the HMNS trip to Ethiopia.

Astute readers may have noticed that volunteering at HMNS is often a “family affair,” and there are many families who volunteer together — husband and wife (like Inda and Neal), parents and young adult/adult children, even grandparents and grandchildren. For example, Julie Swank, a summer volunteer on break from Baylor University, took photos of her grandmother and interviewed her for this blog! Barbara McClintock has several family members who have joined her at HMNS — son John McClintock, daughter Margaret Slutz, and daughter-in-law Susan Peterson.

Second-generation docents Jody Vaughan and Peyton Barnes.

Peyton Barnes and Jody Vaughan are both “second-generation” volunteers. Peyton, a retired surgeon, only became a volunteer three years ago — but his mother, Mrs. J. Peyton (Gertrude) Barnes, Sr., preceded him and served as Guild President in 1971-1972. Jody’s mother, JoLene Whitehurst, was an HMNS volunteer in the 1970s. An RN, she worked in the museum’s health and biology area, which featured a giant mouth and toothbrush, a life-sized transparent plastic body named Tammy, and models of human development from zygote to newborn. HMNS was an important part of Jody’s childhood — her Mom even gave her a museum membership as a wedding gift! Jody is honored to follow in her mother’s footsteps as an HMNS docent and fondly recalls bringing her Mom back to the museum after becoming a docent herself.

So why don’t you yourself make some lasting memories, share some quality family time, or simply join the fun by becoming a volunteer at HMNS? You can join us, too! No advanced degrees required, and prior scientific knowledge isn’t necessary — just interest and enthusiasm. Information on volunteering is available on the museum’s website. Consider giving your body to science, and maybe we’ll see you in the halls!

Hate Mosquitoes? Consider a Bat House! Fight Insect-Borne Illness by Partnering with Furry Fliers

The National Weather Service reported last week that 35 trillion gallons of water fell in the state of Texas during the month of May. The ground is soaked for what may well be weeks to come, our bayous have swollen far beyond their usual limits and residents in Harris and Ft. Bend counties continue to pick up the pieces after flooding pushed them from their homes. We know what 35 trillion gallons looks like in terms of disrupting the lives of Texans, but it’s difficult to imagine just exactly how much that is.

bats4

That’s a lot of water…

NBC’s Nelson Hsu put together a graphic breaking down the staggering amount of water that drenched our state — evenly distributed and dropped all at once, it’s enough to cover Texas in eight inches of water; enough to fill California’s 200 surface reservoirs to thrice their capacity, enough to cover Manhattan four times, and if we had caught all that rainwater and spread it across the globe, the world’s population would have a supply of 64 ounces of water for at least the next 27 years. And most people fail the eight-glasses-a-day challenge!

With Zika virus making headlines in the aftermath of May’s downpour, our soaking city seems like prime real estate for ground zero of the next outbreak. But fear not. Mosquitoes are ubiquitous, that’s true, but they’re easy enough to fight. They fly at less than 1.5 miles an hour, with a typical range of only about 300 feet in still weather. Their strength is in their numbers, not their speed — kind of like zombies.

America’s worst enemy, but to bats, they’re food for thought.

First, there have as yet been no locally-acquired cases of Zika virus in the United States, according to the Center for Disease Control; the 618 reported cases were all travel-associated. It’s also important to understand that while Zika poses a serious threat to developing infants during pregnancy, the disease presents no more than a few days of flu-like symptoms in adults and children.

Second, since mosquitoes are the main vector of Zika, the best way to directly combat them is to wear insect repellent. Sure it smells nasty, but Off! and other spray-on products could save you from serious symptoms and the awful itching of the world’s most annoying insect.

Third, you can stop mosquitoes from breeding by eliminating areas of shallow, stagnant water. Take a lesson from the residents of Flamingo, Fla., a community in the Everglades and home to one of the most voracious populations of mosquitoes: Get rid of aluminum cans, bottles and plastic containers, store recycling in plastic bags, don’t let water accumulate in garbage can lids or empty garbage cans, flush bird baths and plant trays twice a week, store pet food and water bowls indoors when Fido and Felix aren’t using them, and use mosquito “dunks” in areas that can’t be drained. These dunks utilize bacteria that consume mosquito larvae but leave fish and other animals unharmed.

(Yawn!!!) It it dusk yet? I’m hungry for mosquito breakfast.

For the long term, my favorite method of laying waste to mosquitoes involves enlisting the assistance of another population of flying creatures — by hanging bat houses! The Mexican free-tailed bat (Tadarida brasiliensis) is a hardy, numerous species (and they’re super cute), but their propensity to roost in a few huge colonies, like those you can find under bridges in Austin and Houston, leaves them vulnerable to habitat loss. Hanging one or two bat houses around your home keeps these adorable flying mammals close by, which means far fewer insects.

Vote Bat for Harris County Mosquito Exterminator! I eat bugs so they don’t eat you!

While female mosquitoes have an insatiable appetite for blood, which they need to lay their eggs, bats have an equally ravenous hunger for the insects. A single bat can eat around 1,000 mosquitoes every night, and a single small bat house offers shelter for up to 25 bats. Do the math with me — two shelters is 50 bats, which could eat a total of 50,000 mosquitoes a night or 350,000 mosquitoes a week. That’s not just the mosquitoes around your house; that’s probably every mosquito on the block. If you convince your neighbors to hang houses, too, you could form a bat colony coalition for an even more formidable mosquito-fighting force.

When we have a problem, we hug it out. #justbattythings

The capacity of a bat house, of course, is also adjustable according to its size. Many bat house companies, like P & S Country Crafts or Habitat For Bats offer a variety of dimensions available for purchase, or you can build one yourself. It’s an easy enough project to knock out in your garage in a few days, and an even easier project to hang up a pre-made one. Each house promotes an environmentally-friendly semi-symbiotic relationship with our adorable bat friends, which stay long enough to raise their pups and then move on when the weather cools down. And by this time, the mosquitoes will have disappeared for the season, as well.

So do what you can to fight mosquitoes, but consider teaming up with the bats, our neighborhood insect-fighting superheroes. Check out Bat Conservation International for more information on ways to help these furry fliers.

Exploring the Natural Sciences with Blocks: It Can Be Done!

Nothing inspires both children and adults quite the way a museum does. A close second is the inspiration that both the young and old find playing and experimenting with various kinds of toys that encourage building and construction.

Exploration of the natural sciences and imaginative construction play are a natural fit. The museum’s new exhibit Block Party provides a unique opportunity for families to first explore the natural sciences in the museum’s exhibit halls and then to experience hands-on creative exploration as they get up to their elbows in interlocking bricks that can be used to build anything imaginable!

It’s well-established that block or building play are ideal avenues to develop fine motor skills, hand-eye coordination, capacity for divergent thinking, collaborative skills, and spatial thinking in children. In addition, there’s evidence connecting complex block play and construction toys with advanced math skills in later life. Building play is also beneficial for the brains of tweens and adolescents, and don’t be fooled, they still love to build and play. Recent studies link construction play with superior performance on tests of spatial skills and mathematics for older children.

Structured block play is a term used when a child attempts to recreate a construction by consulting a model or blueprint. This kind of block play calls on a specific skill set that is crucial for many complex tasks. Why not take advantage of the various opportunities available at the museum to collect inspiration for structured block play?

In order for your child to build a recreation of something they observed in the museum, they have to analyze what they saw, perceive the parts that made up the whole, and figure out how the parts relate to one another. Here are some great ideas to get you started. Visit the exhibits and then visit Block Party to build and explore. Please share the great ideas you and your children come up with, and don’t forget to submit your creation to our weekly contest!

Frankenbirds: A True Story of Science and Immortality, or, How to Make Dead Animals Look Alive

by Sabrina Dahlgren

I’d like to first clarify that this is not a “how-to” manual for your creep-tastic Halloween needs. I’m all for phantasmagorical home decor but the average citizen should not be handling animal specimens. Numerous species are protected or their handling is regulated by state and federal authorities. If you don’t have the necessary permits and training please leave the dead stuff alone (or call us).

7

Order: Piciformes.

With that disclaimer in place, I’d like to boast that my necropsy (animal autopsy) skills have greatly improved in my time at the Houston Museum of Natural Science. As has my taxidermy technique – not a skill set I thought I’d be adding to my resume, but this place is nothing if not constantly surprising.

1

Order: Strigiformes.

Why is this done at all, you may ask? As a scientific institution, part of our job is to preserve a record of life on Earth, both for edification of the public (think the Farish Hall of Texas Wildlife and the Frensley/Graham Hall of African Wildlife) and for the maintenance of reference collections used in research (our study skin specimens stored off-site).

It may seem like an obvious assumption, but no one wants to store an untreated dead thing in their building, regardless of ventilation and air-conditioning. Dead things rot, rotten things smell bad and a stinky workplace makes for very unhappy employees. So unprocessed specimens are stored in a freezer until the time comes for someone like me to thaw it out and clean it up. The cleaned skin is either made into a display mount or into a study skin, as much data is gathered as possible, and all records and databases are updated to reflect the newest addition.

What a difference strategic feather placement can make! Juvenile Black-Crowned Night Heron. Nycticorax nycticorax.

So what kind of person does this for a living? Am I the modern, non-fiction equivalent of Victor Frankenstein? So glad you asked! Here’s the answer, in brief:

In presentation I lean more towards lab coat and nitrile gloves than I do mad-scientist hair and demented cackling.

10

5

The resemblance is uncanny.

My lab consists of a tiny room with two freezers, a small fridge, storage cabinets, a section of counter well-lit by under-cabinet lights, and a sink; not a condenser coil nor galvanic rod in sight.

11

4

A Tesla coil would add to the ambiance…

There is no Fritz or Igor to assist; the closest I come is Pandora or Spotify to pass the time. The best and most ironic song I listen to is The Vulture Song from Disney’s The Jungle Book because I am a ridiculous human being and a morbid sense of humor serves well when I do this work, especially in October.

Most of my tools are normal: scalpels, dissecting scissors, probes and pins. Grocery items are also used: cotton balls, Q-tips, hydrogen peroxide, borax, Dawn dish soap, and an impressive amount of paper towels. Some of my tools are a bit unorthodox. Gardening shears have become one my most useful tools. Toothbrushes have become specimen dinglehoppers. You don’t even want to know what I use a teaspoon for. (Hint: It’s a fat scraper. Enjoy that bit of TMI.)

12

Hair dryer + toothbrush = bird salon.

Regarding the actual preparation:

  • Documentation is key – keep a written record of all observations and data that may have accompanied the specimen. Take pictures for reference. Or just because.
  • Record external data (weight, visible trauma, general condition, etc.).
  • Skin the specimen. You’ll end up with bone only in the lower legs and feet, wing extremities, and the cranium; organs, muscle, and adipose (fat) should be removed.
  • Clean the skin as thoroughly as possible – cleanliness equals longevity and that’s the big goal.
  • Clean the feathers and the exterior of the specimen as needed.
  • Fill the eye sockets with cotton  for a study skin and glass eyes for a mount.
  • Reinforce the length of the body with a dowel, then add in stuffing to re-form the body cavity. If you’re preparing a mount, add wire armature inside first so that it will hold a pose, then stuff.
  • Stitch up any incisions or tears in the skin and brush the feathers back into place.
  • Secure the specimen on a foam board and allow to dry for one to three weeks, depending on the size and condition of the specimen.

Unlike Doctor Frankenstein, I am happy to report that I do not galvanize specimens. The only electricity I use is restricted to the lights and the hair dryer, not for reanimating the bird.

…it better not be alive.

Why is any of this important? Simple. Scientists like data. Scientists like data even more if there are visual references available. If those reference materials preserve individual variations among species, observations and inferences can be made concerning species and larger taxa of organisms. Our collection is, essentially, a 3-D reference library that will serve future generations.

And that’s pretty amazing, if you think about it.

So there you have it: the key components of a specimen preparation specialist.

Scientific background + morbid curiosity + Disney references + off-color humor = Sabrina.

This is an ex-parrot.

And now I’m off to calculate the air speed velocity of an unladen European Swallow (Hirundo rustica).

P.S. Someone has already done the math, and it is beautiful.

…and this is a gratuitous Monty Python reference.
