Bread worms or replace the meat in the future become the table's most fortified foods
Accordingcar dvr to foreign media reports, have an interest in agricultural products "cargo" are or soon will be able to eat the meat of a new alternative: insects.
Recently, the Netherlands Wah Nanjing University (University of Wageningen) Dennis-aoningkesi (Dennis Oonincx) and his colleagues published in the vehicle dvr journal PLOS ONE, a research report. Reports that use the same size of land, bread of transgenic farm produce than traditional chickens, pigs, and cattle farms more edible protein.
Researchers use three parameters, "Baker's worm farm environmental effects of meat production process" and "traditional poultry livestock farm environmental effects of meat production process" were compared, these three parameters are: land-use, energy and greenhouse gas emissions. Starting from the experiment until the meat product is output, researchers found that insect bread score higher scores than the other food. From the perspective of production per unit of protein content, bread worm farming requires vehicle dvr less land and energy.
As early as 2010, the research team has done similar research, report bread insect emissions of greenhouse gases than other poultry for meat production purposes less greenhouse gas emissions from livestock.
Comments on the research results, aoningkesi said: "due to the Earth's population is increasing and the limited amount of land, there is an urgent need for a more effective and more sustainable food production systems. Now, with such insect characteristics of production systems in car dvrthe bread for the first time in the breeding process, perhaps other edible insect farming process can also have these features. ”
NASA planned to catch 500 tons of asteroids to build space stations for rockets
United States Mission of NASA's new space mobile dvr
suits and the Star model of how much alike: from these recent photos do not see United States NASA's version is not from the buzz light years, but they looked very much alike
SINA Tech News Beijing time on December 25, according to foreign media reports, the United States NASA scientists are planning to capture a 500-ton asteroids, redeployment and it, and turned it into a space station, astronauts going to Mars to provide some help.
United States White House Office of science and technology policy prepared 10 years of space exploration in the future arrangements will take into account this need in coming weeks at a cost of 1.6 billion pounds (US $ 2.585 billion)car dvr plan. If the plan is approved, it will become the first-ever human movement of celestial bodies. United States NASA and the California Institute of technology in preparing a feasibility report, scientists outlined how they captured asteroids. An "asteroid captured space ship" will be tied to an old "Atlas 5" rockets, used to guide an asteroid is located between the Earth and the moon. Then the aircraft will turn on thruster, using approximately 300 kg of propellant block the target asteroid, and drag it to a point of gravitational balance point. Space explorers will fly to space it as a deeper fixed base.
The report said: "the idea of using asteroids that natural resources can be dated back to hundreds of years ago, but as of now we only have to turn it into a reality of technology. 3 key developments to capture asteroids into practical matters, these three areas are: identify and qualify a to catch and return to the characteristics of the near-Earth asteroids; by tapping the power of solar electric propulsion system's ability to transport captured asteroid; and suggestions of what's in the 2020 of the 21st century appears in the space between the Earth and the Moon, explore and take advantage of this back to the asteroid. "The United States Space Agency declined to comment on the project, because it claims that they are working with the White House deliberations, but they believe that technology development within 10-12 years to turn it into a reality. The technology will also create possibilities for mining other minerals on an asteroid. Iron can be used to make some of the new space station, other water minerals can be broken down into hydrogen and oxygen as fuel.
Earlier this year, Seattle company Planetary Resources said that it intended to begin production within the next 10 years, "near-Earth asteroids" on the deposits. The company's investors include former United States presidential candidate Ross-Perot Eric-Schmidt and Larry-page, and Google. This project intends to 2016, using a spacecraft to the asteroid 1999 RQ36, and bring samples back to Earth origins spectral interpretation resource identification security-weathering layer of detectors (OSIRIS-REx) plan consistent with the idea. Hoped that the project vehicle dvr would increase our understanding of the asteroids, or even help the identification of the origin of life on Earth. 1999 RQ36 is coming from in the early solar system one of the most accessible of organic-rich asteroids, its average diameter is approximately 1600 feet (487.68 m), or about 4 football pitches. In fact that asteroids are rich in carbon, this important component of organic molecules is essential for life, that is to say, it explains more and issues relating to the composition of life on Earth.
United States NASA has invited scholars from around the world for the 1999 RQ36 a better name. A panel will review the proposed asteroid names, the International Astronomical Union (IAU) under the small celestial body named the Committee ratified the final chosen name. University of Arizona, the Mission's principal investigator Dante-Lauretta said: "our task will be to focus on the asteroid for more than 10 years. We hope to have a manned mission than repeated names easier to read, and want this task to contribute to the future of space travel experience. "Once you make any more distant space exploration, astronauts are likely to be wearing a new suit, this news last week appeared on the photo-sharing site Flickr. The new suit design similar to the buzz light year wears suits.
A huge hemispherical transparent enclosure cover on the wearer's head, looks similar to the buzz light year, but from these recent photos do not see United States NASA's version is not from the buzz light year. Compared with the original version, United States Space Agency's main improvement is, behind the new suits will have a lead, it makes it more convenient than previous suits. Astronauts as fast as you can see in the video be crawling, and now they wear space suits can take up to 1 hour. New suit mobile dvralso has its own air lock, so you don't have to spend a lot of time for clothes to achieve the appropriate pressure. New clothes the legs, ankles, hips and wrists to install better bearings, also helps astronauts more comfortable moving the body, nylon and polyester ethylene and coating layer can more effectively control the pressure. Z-1 space package (Z-1 PLSS 2) are expected to be applied to the reality in the coming years.
