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.

動物実験と論文で言及された人間研究プロジェクトの間には、1つの大きな違いがありました: 研究者は、以前の調査では、動物が食べるものを制限しました、他方、人間の場合は、彼らの食事行動を報告しました。このように、バートケ博士が言うように、データの質には疑問があります。研究者が動物の調査対象に食べさせる物に関して注意深い記録を残し、動物が他の食物源から食物を得るのを防止する限り、研究者は食物摂取測定を信頼することが出来るでしょう。しかし、人間は、実験用のネズミではないのです。人間が経験する環境を完全にコントロールすることは、倫理的ではありませんし、一般に可能ではないのです。この場合、「食事集団」の被験者に対する食事をコントロールすることは、たぶん経費的に可能ではありませんでした。その結果、研究者は、これらの被験者から得られる自己申告のデータに頼りました。実際にカロリー摂取量を30%削減したと報告したメンバー全員が、実際に削減したと言うことは、とてもあり得ないように思えます。 もしも、被験者が食事を制限し、彼らの行動を観察できるならば、我々は、集団のメンバーが、彼らのカロリーを実際に30%減らしたことを認めることができるかもしれません。しかし、その場合でも、3カ月かけて研究室の環境へ通うことができた一団の人々が、一般的な母集団を代表していないかもしれないことが懸念されるでしょう。

    “Unlike previous investigations, we were able to assess association of consumption of caffeinated and non-caffeinated beverages, and we identify caffeine as the most likely candidate of any putative protective effect of coffee,” said lead researcher Michel Lucas, research fellow in the Department of Nutrition at HSPH. The authors reviewed data from three large U.S. studies and found that the risk of suicide for adults who drank two to four cups of caffeinated coffee per day was about half that of those who drank decaffeinated coffee or very little or no coffee. Caffeine not only stimulates the central nervous system but may act as a mild antidepressant by boosting production of certain neurotransmitters in the brain, including serotonin, dopamine, and noradrenaline. This could explain the lower risk of depression among coffee drinkers that had been found in past epidemiological studies, the researchers reported. In the new study, researchers examined data on 43,599 men enrolled in the Health Professionals Follow-Up Study (HPFS) (1988–2008), 73,820 women in the Nurses’ Health Study (NHS) (1992–2008), and 91,005 women in the Nurses’ Health Study II (NHSII) (1993–2007). Caffeine, coffee, and decaffeinated coffee intake was assessed every four years by questionnaires. Caffeine consumption was calculated from coffee and other sources, including tea, caffeinated soft drinks, and chocolate. However, coffee was the major caffeine source — 80 percent for NHS, 71 percent for NHS II, and 79 percent for HPFS. Among the participants in the three studies, there were 277 deaths from suicide. In spite of the findings, the authors do not recommend that depressed adults increase caffeine consumption, because most individuals adjust their caffeine intake to an optimal level for them and an increase could result in unpleasant side effects. “Overall, our results suggest that there is little further benefit for consumption above two to three cups/day or 400 mg of caffeine/day,” the authors wrote. The researchers did not observe any major difference in risk between those who drank two to three cups of coffee per day and those who had four or more cups a day, most likely due to the small number of suicide cases in these categories. However, in a previous HSPH coffee-depression study published in JAMA Internal Medicine, the investigators observed a maximal effect among those who drank four or more cups per day. One large Finnish study showed a higher risk of suicide among people drinking eight or nine cups per day. Few participants in the two HSPH studies drank such large amounts of coffee, so the studies did not address the impact of six or more cups of coffee per day.

    New research finds link between frequency of exercise and stroke risk Here’s yet another reason to get off the couch: new research findings suggest that regularly breaking a sweat may lower the risk of having a stroke. A stroke can occur when a blood vessel in the brain gets blocked. As a result, nearby brain cells will die after not getting enough oxygen and other nutrients. A number of risk factors for stroke have been identified, including smoking, high blood pressure, diabetes and being inactive. For this study, published in the journal Stroke, Michelle N. McDonnell, Ph.D., from the University of South Australia, Adelaide and her colleagues obtained data from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study. REGARDS is a large, long-term study funded by the NIH National Institute of Neurological Disorders and Stroke (NINDS) to look at the reasons behind the higher rates of stroke mortality among African-Americans and other residents living in the Southeastern United States. “Epidemiological studies such as REGARDS provide an important opportunity to explore race, genetics, environmental, and lifestyle choices as stroke risk factors,” said Claudia Moy, Ph.D., program director at NINDS. Over 30,000 participants supplied their medical history over the phone. The researchers also visited them to obtain health measures such as body mass index and blood pressure. At the beginning of the study, the researchers asked participants how many times per week they exercised vigorously enough to work up a sweat. The researchers contacted participants every six months to see if they had experienced a stroke or a mini-stroke known as a transient ischemic attack (TIA). To confirm their responses, the researchers reviewed participants’ medical records. The researchers reported data for over 27,000 participants who were stroke-free at the start of the study and followed for an average of 5.7 years. One-third of participants reported exercising less than once a week. Study subjects who were inactive were 20 percent more likely to experience a stroke or TIA than participants who exercised four or more times a week. The findings revealed that regular, moderately vigorous exercise, enough to break a sweat, was linked to reduced risk of stroke. Part of the protective effect was due to lower rates of known stroke risk factors such as hypertension, diabetes, obesity and smoking. “Our results confirm other research findings but our study has the distinct advantage of including larger numbers, especially larger numbers of women as well as blacks, in a national population sample so these provide somewhat more generalizable results than other studies,” said Virginia Howard, Ph.D., senior author of the study from the School of Public Health, University of Alabama at Birmingham.

    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.

    On September 24, Grand Duke Nicholas was promoted to being charge of all Russian forces in the Caucasus. In reality, he was removed from being Supreme Commander of the Russian Caucasus Army which was the highest executive position [actual conduct of the war] for the Caucasus Campaign. His replacement was General Yudenich. This front was quiet from October till the end of the year. Yudenich used this period to reorganize. Around the start of 1916, Russian forces reached a level of 200,000 men and 380 pieces of artillery. On the other side the situation was very different; the Ottoman High Command failed to make up the losses during this period. The war in Gallipoli was sucking all the resources and manpower. The IX, X and XI Corps could not be reinforced and in addition to that the 1st and 5th Expeditionary Forces were deployed to Mesopotamia. Enver Pasha, after not achieving his ambitions or recognizing the dire situation on other fronts, decided that the region was of secondary importance. As of January 1916, Ottoman forces were 126,000 men, only 50,539 being combat. There were 74,057 rifles, 77 machine guns and 180 pieces of artillery. Ottoman force in Caucasus Campaign was big on the paper, but not on the ground. The Ottomans assumed that the Russians would not bother to attack. This assumption turned out to be false.

    Pink and blue arrived, along with other pastels, as colors for babies in the mid-19th century, yet the two colors were not promoted as gender signifiers until just before World War I—and even then, it took time for popular culture to sort things out. Today’s color dictate wasn’t established until the 1940s, as a result of Americans’ preferences as interpreted by manufacturers and retailers. “It could have gone the other way,” Paoletti says. So the baby boomers were raised in gender-specific clothing. Boys dressed like their fathers, girls like their mothers. Girls had to wear dresses to school, though unadorned styles and tomboy play clothes were acceptable. When the women’s liberation movement arrived in the mid-1960s, with its anti-feminine, anti-fashion message, the unisex look became the rage—but completely reversed from the time of young Franklin Roosevelt. Now young girls were dressing in masculine—or at least unfeminine—styles, devoid of gender hints. ″Feminists thought that girls were kind of lured into subservient roles as women is through clothing,” says Paoletti. “ ‘If we dress our girls more like boys and less like frilly little girls . . . they are going to have more options and feel freer to be active.’ ” John Money, a sexual identity researcher at Johns Hopkins Hospital in Baltimore, argued that gender was primarily learned through social and environmental cues. “This was one of the drivers back in the ’70s of the argument that it’s ‘nurture not nature,’ ” Paoletti says. Gender-neutral clothing remained popular until about 1985. Paoletti remembers that year distinctly because it was between the births of her children, a girl in ’82 and a boy in ’86. “All of a sudden it wasn’t just a blue overall; it was a blue overall with a teddy bear holding a football,” she says. Disposable diapers were manufactured in pink and blue.

    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.

    From the time that life first appeared on Earth, species have gone extinct. Extinction is a natural part of evolution. Species that are best at adapting to their environment survive. Other species are unable to adapt quickly enough – so they die off. So, why do endangered species get so much attention today? One reason is much of the extinction happening these days is unnatural. The leading reason for a species to become endangered is loss of habitat. As humans cut down forests for farmland, expand cities, or pollute waterways, to name a few ways that habitat is destroyed, animals, plants, and insects find it harder and harder to survive. Thus, the effect of humans on the natural world is causing species to become endangered, and, ultimately, go extinct. Another leading reason for a species to become endangered is climate change. For example, the lizards in this article could probably adapt to a gradual change in temperature. However, the rapid change in the climate, and the consequent decrease in lizard birthrate, threaten to doom many lizard species. If human activity is a major reason for climate change, then it would seem that we are changing our world far too rapidly for species to naturally adapt. Humans are highly adaptable, but most species need a lot of time to get used to changing conditions.

    Fancy living 100 years more? Some experts say scientific advances will one day enable humans to last decades beyond what is now seen as the natural limit of the human life span. An American professor says advances in manipulating cells and genes as well as nanotechnology will make it likely that humans will live much longer in the future. Many other scientists specializing in aging are skeptical of such claims. They explain that the human body is not designed to last more than 120 years. They add that even with healthier lifestyles and less disease, failure of the brain and other organs will eventually condemn all humans.

After 17 June the proposal from Churchill of 11 May 1953 to work at the highest level with the Kremlin towards an arrangement on a neutral all-German solution was robbed of any basis. The victors of the Second World War remained Allies, true to their principles, against Germany even through the period of 17 June 1953, particularly since they were dealing primary with the security and consolidation of their areas of interest in relation to the German partial states
