表姐与乳腺癌斗争的事例历启发了温格寻找更好的方法诊断疾病。

现已17岁的布列塔尼•温格(Brittany Wenger)称自己仍然像学步阶段的孩子,总喜欢问“为什么”。

十几岁的布列塔尼来自佛罗里达州的萨拉索塔(Sarasota)。她说:“直到我认识了科学之后,我才找到了我要的答案——然后我又有了更多的问题,因为科学就是这样,你知道的越多,要问的也就越多。”

一位表姐与乳腺癌的斗争启发温格创造了诊断疾病的人工神经网络。她让电脑能够通过分析針吸細胞活檢術采集的细胞,确定乳腺肿块是否是恶性或良性。針吸細胞活檢術是侵入性最轻的活检手段。现在,她编制的程序对恶性肿瘤的敏感率为99.1%。她说如果有了更多的数据,可通过鉴定供医院临床使用。

温格的研究已经为她在谷歌科技博览会(Google Science Fair )和英特尔国际科学展(Intel International Science Fair)上赢得了奖项。

温格说,科研本身除了是一种乐趣外,还使她“能遇到来自世界各地的其他孩子和激励我的著名科学家。”

温格说,科学“让我有机会参与改善人类生存条件的事业。”

Brittany Wenger: The Kid Who Never Outgrew the “Why” Stage


14 January 2013

A cousin’s battle with breast cancer inspired Brittany Wenger to find better ways to diagnose the disease.

Now 17 years old, Brittany Wenger calls herself “that kid who never outgrew the ‘why’ phase” of toddlerhood.

“It wasn’t until I found science,” says the teen from Sarasota, Florida, “that I found my answers — and more questions, because with science, the more you know, the more you wonder.”

A cousin’s battle with breast cancer motivated Wenger to create an artificial neural network to diagnose the disease. She taught a computer how to determine whether a breast mass is malignant or benign by analyzing cells collected from fine needle aspiration, the least invasive form of biopsy. Her program is now 99.1 percent sensitive to malignancies, and with more data it will prove to be hospital-ready, she says.

Wenger’s research has won her awards in the Google Science Fair and the Intel International Science Fair.

In addition to being a joy in itself, scientific research, Wenger says, has enabled her “to meet other kids from all around the globe and renowned scientists who inspire me.”

Science, Wenger says, “gives me an opportunity to be a part of something that can improve the human condition.”
