Second round of direct observation to the success of the gravitational wave.

Research team, such as California Institute of Technology is 15 days, the black hole is direct observation of the second round of gravity waves generated when combined
It announced that it had succeeded in.
 In feat following the success of the first observation, which was announced in February this year, advance and elucidation of difficult was the black hole of the mechanism in a conventional telescope
It is expected that.
According to the research team, a giant observation device called a "LIGO" which is in the western United States and southern, each December last year
Detects a distortion of space-time can be seen with the gravity wave in 26 days. Mass 14-fold and 8-fold in the black hole of the sun coalesced to 14 million years ago
When in, distortion of energy corresponding to the mass of one piece of the sun spread in the universe as a gravitational wave, believed to have arrived on Earth.
For the second time of observation success, Chad Hanna Dr. of Pennsylvania State University research team (to observe the universe with gravitational waves) "
Future of gravitational wave astronomy has been pointed out that bright's achievement that can be confident that ".
We hope that the mystery of the universe is going to be elucidated through the observation of gravitational waves.



 米カリフォルニア工科大などの研究チームは１５日、ブラックホールが合体した時に発生した重力波の２回目の直接観測に成功したと発表した。
 今年２月に発表した初観測の成功に続く快挙で、従来の望遠鏡では難しかったブラックホールの仕組みの解明などが進む
と期待される。
　研究チームによると、米国西部と南部にある「ＬＩＧＯ」と呼ばれる巨大観測装置で、それぞれ昨年１２月
２６日に重力波とみられる時空のゆがみを検出した。質量が太陽の１４倍と８倍のブラックホールが１４億年前に合体した
際に、太陽１個分の質量に相当するエネルギーのゆがみが重力波として宇宙に広がり、地球に届いたとみられる。
　２度目の観測成功に、研究チームのペンシルベニア州立大のチャド・ハンナ博士は「（重力波を使って宇宙を観測する）重力波天文学の将来が明るいと確信できる成果だ」と指摘している。
　重力波の観測を通じて宇宙の謎が解明されていくことを期待します。

I hope a variety of cancers is to be found by urine.

Hitachi, Ltd. and Sumitomo Corporation Group has announced that it has developed a 14 days, the world's first technology to find the breast and colon cancer by examining the urine.

Has to be used within the next few years, it is expected that in the future lead to a significant simplification of the cancer screening.

According to the announcement, it was able to narrow down from more than 1,300 substances, such as sugar and lipids found in the urine, up to about 10 kinds of specific substances required in order to determine with cancer. In the difference between the content that can distinguish healthy subjects and cancer patients.

Because it is easy compared to, such as X-ray examination and blood test, the burden of the people to receive a medical examination is made lightly. However, it has been left with issues such as analysis of the structure of a particular substance, to accelerate the research for practical use of early. I hope a variety of cancers is to be found by urine.

日立製作所と住友商事グループは１４日、尿を調べることで乳がんと大腸がんを見つけられる世界初の技術を開発したと発表した。

数年以内の実用化を目指しており、将来的にがん検査の大幅な簡略化につながると期待される。

　発表によると、尿の中にある糖や脂質など１３００以上の物質から、がんと判定するために必要な特定物質を約１０種類まで絞り込むことに成功した。その含有量の違いで健常者とがん患者を見分けられるという。

　エックス線検査や血液検査などに比べて手軽なため、検診を受ける人の負担が軽くなる。ただ、特定物質の構造の解析など課題が残されており、早期の実用化に向けて研究を加速する。様々なガンが尿によって見つけられるようになるといいですね。
