眾所周知，指紋檢驗在刑偵中占據(jù)了重要地位。但除此之外，指紋科學(xué)還能在其他方面派上大用場。因為，指紋里還藏著我們的不少秘密……

Before the discovery of DNA profiling in the 1980s，fingerprints weretheeasiestway to solveserious crimes.

It's believed thatof the 7 billion or so people on Earth，each one of us has our own unique fingerprints.

But did you know that our fingerprints could actually reveal a lot more about us than just our identity?

According to Melanie Bailey of The Conversation，fingerprints can indic ate lifestyle and environment，eating habits，possible medical problems and even the job of a person.

So how can wefigureall thisoutfrom just a simple fingerprint?

Well，a fingerprint is formed when a fingermakes contact witha surface.Most fingerprints are invisible to the naked eye and require a chemical development process in order to make them visible.Stuck between the ridges of a fingerprint， however， are what can tell a story about who we are.Things like traces of sweat， blood， and food reveal a lot of information about us—what we've touched， what we've eaten and even what drugs we've taken.

At the moment，the techniqueused to detectthese substances is mostly used in crime detection，but its application could be much wider，according to Bailey，who lectures in chemistry at the University of Surrey in the UK.For example，she and her fellow researchers were able to tell what medicines people were taking from their fingerprints，which may be of great help in the future to doctors treating their patients.

A fingerprint check may also be able to tell a doctor whether a patient is properly absorbing a drug they've been prescribed.In the treatment of some of the most serious illnesses，it's vital thatthe body istaking inthese medicines.AsScientific Americannoted，this is particularly important for patients undergoing treatment for cardiac（心臟的）conditions and psychosis，as these people might struggle to absorb the drugs or forget or even choose not to take them.

And while it's commonly believed that our fingerprints never change， in fact， they do—and the way they change can provide a lot of very useful information.In the future，fingerprint science won't be restricted to the crime lab but could help doctors keep us in the best possible health.

在20世紀(jì)80年代DNA分析技術(shù)問世之前，指紋是破解重大刑事案件最容易的方法。

人們相信，在地球約70億的人口中，每個人的指紋都獨一無二。

但你知道嗎？除了我們的身份，指紋其實還可以透露更多信息。

“對話”（The Conversation）網(wǎng)站的梅蘭妮·貝利認為，指紋可以體現(xiàn)一個人的生活方式、所處環(huán)境、飲食習(xí)慣、潛在的健康問題甚至職業(yè)。

所以我們?nèi)绾螐囊幻缎⌒〉闹讣y中獲知這一切呢？

當(dāng)手指和物體表面接觸時，指紋就形成了。大多數(shù)的指紋都并非肉眼可見，需要經(jīng)過化學(xué)顯影處理來讓它們“現(xiàn)形”。而在指紋隆起的紋路之間就隱藏著包含我們信息的物質(zhì)。汗?jié)n、血液以及食物的痕跡透露了許多關(guān)于我們的信息——像接觸了什么、吃了些什么、甚至是吃了什么藥。

擔(dān)任英國薩里大學(xué)化學(xué)講師的貝利表示，現(xiàn)今，檢測這些物質(zhì)的技術(shù)大多用于刑偵，但其應(yīng)用可以更為廣泛。例如，她和科研同事們能夠通過指紋判斷人們服用的藥物，這點或許將來在醫(yī)生治療病患時能派上大用場。

指紋檢驗或許還能告訴醫(yī)生病患是否能充分吸收所開的處方藥。在治療某些最為嚴(yán)重的疾病時，人體對這些藥物的吸收至關(guān)重要。正如《科學(xué)美國人》雜志所指出的那樣，這點對心臟病病人和精神病人而言尤為重要，因為這些病人或許難以吸收藥物，或者忘記甚至選擇不服藥。

而盡管人們普遍認為指紋永遠不會變，但實際上，指紋的確會改變——而它們改變的方式也能提供大量有用的信息。在將來，指紋科學(xué)并不會局限于犯罪實驗室，還能助醫(yī)生一臂之力，讓我們盡可能地保持健康。
