Scientific investigation is not only used to advance science - sometimes scientific procedures are used to investigate a crime or to provide evidence in a criminal trial. This application of scientific methods for legal use is the fast-growing area known as "forensics." For example, when DNA, blood, a fingerprint, hair, or other tissue is found at a crime scene, investigators can often match the sample to the person from whom it came. Now we have learned that DNA samples that are found at the crime scene may be able to give us information about a person's eye color. As exciting as this development is, we should keep in mind that matching DNA from a sample to a suspect is still not very accurate. In fact, the most important use of DNA samples may be to eliminate people from suspicion. It is not possible to state with nearly 100% certainty that a particular DNA sample is from a particular person. However, it is possible to state with certainly that a particular sample did not come from a particular person. In recent years many people who were wrongly convicted of crimes have been cleared because their DNA was completely different from DNA found at the scene. Forensic medicine is very important, but it must be used very carefully. Nobody should be convicted of a crime based solely on DNA evidence.

科学的捜査は科学の進歩お進めるためではなく、犯罪の調査など裁判での証拠のためにも使われている。このように法律のために科学を使うのを「法学医」と言い、現在急成長している分野である。 例えば、犯行現場で見つかったDNA,血痕、指紋、髪の毛などを残していった者と照らしあわす事ができる。現場で見つかったDNAからその人の目の色が分かると発見された。喜ばしい進展だが、DNA鑑定はまだ不正確であることを心に留めておく必要がある。DNAは特定の人物からのもの、とは100%の確信を持っていえることではない。しかし、逆にDNA鑑定で絶対にこの者ではないと見極めることは可能なので、これを証拠として免罪が判明した人々が最近増えてきた。法学医は重要な捜査手段でもあるが、利用のときは要注意であり、DNA鑑定のみで有罪が決定するのは誤った方法と考えたほうがいい。

    The article mentions that it took 17 years from the beginning of the investigation to the publication of the 11 papers on Ardi in 2009. During that time only one paper was published by the team members, in 1994. It is interesting that the team did not publish papers on the research for 15 years, for we live in the era of “publish or perish” – in other words, professors understand that they need to publish academic articles in order to keep their jobs, or at least to be able to advance their careers. True, 47 of the 70 investigators on the team were listed as authors on the 11 papers. Also, the publication of the papers all at once essentially guaranteed that the papers were given a lot of attention. Still, it is encouraging that the universities and other institutions that funded the research continued to support the team members despite the lack of papers. After all, “publish or perish” is largely due to the need for universities to be recognized as places where a lot of research is being done. High levels of publication lead to high evaluations, which helps attract students and funding to a particular university. The presence of good students and large research budgets help the school maintain its excellence. So the term “publish or perish” may not be quite as cynical as it first sounds.

    The article mentions that the 50 research subjects were divided into three groups. Thus, each group likely had 16 or 17 members. With such a small sample size, the findings can only be described as preliminary. Even so, the results are very interesting because earlier studies with animals suggested that reduced-calorie diets may improve memory. This study, with its admittedly small sample, backs up the original research and makes it clear that the research should be continued. To be sure, a study done with a larger sample would seem to be the next step. Surprisingly, samples do not have to be very large in order to make accurate predictions about a population. In fact, using a sample is actually more accurate than if data on every member of a large group were collected. For one thing, with a large population, the time required to get data on each member would mean that conditions might change between the beginning of the data collection and the final analysis of the data. Another problem would be that more mistakes in entering the data would occur if too many members were surveyed. Thus, if a proper sample size is selected, and data are collected properly, an accurate prediction about a population can be made even with a relatively small sample.

    There was one large difference between the animal study and the human research projects mentioned in the article: the researchers controlled what the animals in the earlier studies ate, while the humans reported their eating behavior. Thus, as Dr. Bartke mentions, there is a question about the quality of the data. As long as the researchers kept careful records on what was fed to the animal subjects and prevented the animals from getting food from other sources, they could be confident of the food intake measurement. Humans, however, are not lab rats. It is not ethical, or generally possible, to completely control the environment that a human experiences. In this case, it was likely not economically feasible to control the diet for the subjects in the “diet group.” As a result, the researchers relied on self-reported data from these subjects. It is very unlikely that all of the members who reported that they cut their caloric intake by 30% actually did so. If the control their diet and observe their action, then we might be able to accept that the members of the group actually reduced their calories by 30%. However, one would then worry that a group of people who could take three months to go to a lab environment might not be representative of the general population.

    僕に海外の友人が英語について教えてくれているのですが、詳しく知りたいので力を貸して頂けると有り難いです。よろしくお願いします。 * If you say "it does not serve as a bed" that typically means that it is not able to be used as a bed.  In the next sentence you mention that sometimes you like to sleep in it, so a better way to describe what you're saying could be... "A kotatsu will serve as a table, but it's not intended to be used as a bed." This way you're saying that it's not supposed to be a bed, but you could use it that way if you really wanted to. * I wasn't sure if this is what you were trying to say so I guessed.
