![]() ![]() Known as HeLa cells, their stunning potency gave scientists a building block for countless breakthroughs, beginning with the cure for polio. A sample of her cancerous tissue, taken without her knowledge or consent, as was the custom then, turned out to provide one of the holy grails of mid-century biology: human cells that could survive-even thrive-in the lab. Henrietta Lacks was a mother of five in Baltimore, a poor African American migrant from the tobacco farms of Virginia, who died from a cruelly aggressive cancer at the age of 30 in 1951. And from that same life, and those cells, Rebecca Skloot has fashioned in The Immortal Life of Henrietta Lacks a fascinating and moving story of medicine and family, of how life is sustained in laboratories and in memory. ![]() "synopsis" may belong to another edition of this title.Īmazon Best Books of the Month, February 2010: From a single, abbreviated life grew a seemingly immortal line of cells that made some of the most crucial innovations in modern science possible. Intimate in feeling, astonishing in scope, and impossible to put down, The Immortal Life of Henrietta Lacks captures the beauty and drama of scientific discovery, as well as its human consequences. She was consumed with questions: Had scientists cloned her mother? Did it hurt her when researchers infected her cells with viruses and shot them into space? What happened to her sister, Elsie, who died in a mental institution at the age of fifteen? And if her mother was so important to medicine, why couldn’t her children afford health insurance? Over the decade it took to uncover this story, Rebecca became enmeshed in the lives of the Lacks family-especially Henrietta’s daughter Deborah, who was devastated to learn about her mother’s cells. As Rebecca Skloot so brilliantly shows, the story of the Lacks family-past and present-is inextricably connected to the dark history of experimentation on African Americans, the birth of bioethics, and the legal battles over whether we control the stuff we are made of. ![]() And though the cells had launched a multimillion-dollar industry that sells human biological materials, her family never saw any of the profits. Henrietta’s family did not learn of her “immortality” until more than twenty years after her death, when scientists investigating HeLa began using her husband and children in research without informed consent. Now Rebecca Skloot takes us on an extraordinary journey, from the “colored” ward of Johns Hopkins Hospital in the 1950s to stark white laboratories with freezers full of HeLa cells from Henrietta’s small, dying hometown of Clover, Virginia-a land of wooden slave quarters, faith healings, and voodoo-to East Baltimore today, where her children and grandchildren live and struggle with the legacy of her cells. Yet Henrietta Lacks remains virtually unknown, buried in an unmarked grave. HeLa cells were vital for developing the polio vaccine uncovered secrets of cancer, viruses, and the atom bomb’s effects helped lead to important advances like in vitro fertilization, cloning, and gene mapping and have been bought and sold by the billions. If you could pile all HeLa cells ever grown onto a scale, they’d weigh more than 50 million metric tons-as much as a hundred Empire State Buildings. The first “immortal” human cells grown in culture, they are still alive today, though she has been dead for more than sixty years. She was a poor Southern tobacco farmer who worked the same land as her slave ancestors, yet her cells-taken without her knowledge-became one of the most important tools in medicine. Her name was Henrietta Lacks, but scientists know her as HeLa. Now a major motion picture from HBO® starring Oprah Winfrey and Rose Byrne. ![]()

![]() ![]() Uses for amur maple: A good tree for small lots and patio plantings, the amur maple is tolerant of city conditions and is relatively pest free. NOTE: This tree is invasive in central and northern North America. The tree grows relatively upright when young, but it eventually takes on a round-headed appearance. It can be trained as a small tree through pruning or allowed to grow as a tall shrub. It tolerates alkaline soils particularly well. With any treatment it will be necessary to monitor for and treat regrowth and new seedlings in subsequent years.How to grow amur maple: Plant the amur maple in just about any conditions, although it prefers good, well-drained soil and full sun or, at best, partial shade. Herbicide should be selected carefully based on site conditions, and label directions read and followed carefully. Prescribed fire can prevent Amur maple establishment in fire adapted communities such as prairies and savannahs, but must be repeated annually if possible.Ĭhemical control and combined approaches: Cut stump and basal bark herbicide treatment can be applied most of the year, outside of early spring when sap is flowing upward. Mowing can suppress seedling growth near adult plants on managed landscapes, but must be repeated frequently. Roots must be removed to prevent resprouting. Physical control: Small plants are easily hand-pulled from moist soil larger saplings can be dug or pulled using equipment, such as a weed wrench. If control is undertaken on mature plants when seeds are present, it is best not to remove any plant material from the site to avoid spreading seed. Whenever possible, plants should be controlled as seedlings and while populations are small. Natural areas close to places where this species has been planted should be monitored closely for seedlings. Timing and spread concerns: Amur maple is still relatively uncommon around the Great Lakes region, so a good defense is the best offence. For local assistance managing woody invasive species, please get in touch with a cooperative invasive species management group or a university extension program. For more detailed information on how to use these techniques, please visit our Management and Control page. The following is a brief overview of management techniques shown to be effective on Amur maple, though there is relatively little information available about management of this species. Yellow = native to the United States but not to the Basin Green = native to part of the Great Lakes Basin Girard’s paperbark maple ( Acer griseum x nikoense )Ī Listed cultivars have the indicated trait, but the straight species (or hybrid) may not. Alternatives for Amur MapleĬanada serviceberry ( Amelanchier canadensis )Īpple serviceberry ( Amelanchier x grandiflora ), ‘Autumn Brilliance,’ ‘Princess Diana,’ ‘Cumulus’Īmerican hornbeam ( Carpinus caroliniana ) Please see our Landscape Alternatives pages for more information about how the WIGL Collaborative selected alternatives. The leaf shape is somewhat similar to the native ninebark ( Physocarpus spp.), but ninebark has alternate leaves, while those of Amur maple are opposite. Amur maple is much smaller at maturity than any native maple species, with smaller samaras. It is most similar to Tatarian maple ( Acer tataricum ), another small exotic maple with unlobed leaves that frequently has a single main stem. Look-alikes: Amur maple can be distinguished from other maples by its leaf shape, particularly the long middle lobe. The small size of the samaras (each side is ¾ – 1” long) along with the coloration can help distinguish from other maples. Samaras are often pink or reddish in the summer, ripening to brown. They are the papery, winged two-chambered samaras characteristic of maples. Fruits appear over the summer and mature in early-to-mid fall. Flowers are fragrant, unlike other maples. Flowers emerging in mid spring are yellowish white, small, and born in small, branched clusters. Leaf edges are toothed, and leaves are dark green in summer, sometimes changing to yellow or red in fall (fall foliage color varies by cultivar and planting situation). Leaves have three lobes, and the middle lobe is much longer than the side lobes. ![]() The leaves are opposite each other, and are generally 1 ½ to 3” in length. It is common for this species to grow multiple stems and for the crowns to be as wide as the plants are tall. Identification: Amur maple is a large deciduous shrub to small tree, generally 15-18’ tall at maturity. ![]() ![]() ![]() Don’t let them be left behind!

Rollie has more in common with the phlegmatic TV scientist than with the average thriller protagonist, and that's the refreshing thing about both "F/X" movies: Invention counts for more than guns and muscles, and smarts for more than boneheaded rage. A cop-turned-shamus, Leo uses his contacts to get to the bottom of things, while his clever partner baffles the bad guys with Mr. Rollie is reunited with an old buddy, Leo McCarthy (Brian Dennehy), early in the story, though they had just gotten to know each other in the last minutes of the original. With reluctance Rollie agrees to the dangerous scheme, which results in further escapades involving dirty cops, long-lost art objects, the Mafia and the Catholic Church. The three maintain a cordial relationship with her ex-husband (Tom Mason), a police detective who asks Rollie to help set a trap for a killer. In the five years since "F/X," the special effects man has become a successful maker of high-tech toys, with which he delights his girlfriend (Rachel Ticotin) and her 11-year-old son (Dominic Zamprogna). Still, it's an enjoyable bit of smoke and mirrors, thanks to the decency and resourcefulness of its hero. In this second time around for Bryan Brown as special effects whiz Rollie Tyler, the story line is little more than a shiny hat for holding the high-tech rabbits.
