Due to their economy, efficiency and longevity, the internal combustion engine will continue to be the main powerhouse of mobile powertrains**. In order to meet the requirements of environmental protection, researchers have accelerated the development process of zero-emission internal combustion engines.

4. Anti-cancer cells.

Everyone has anti-cancer cells in their body, and the reason why cancer occurs is caused by the sluggishness or weak ability of these anti-cancer T cells. If a way is finally found to activate this ability to fight cancer, the cancer can heal itself completely. Her team has made significant progress in fighting cancer cells.

5. Energy storage.

At present, the urgent problem to be solved in the energy field is not to find or increase energy, but to overcome the problem of energy conservation and energy storage. At present, the main forms of energy storage are nuclear fuel and oil and gas, and the cost of storing electricity is still very high. Renewable energy sources such as wind and solar are replacing fossil fuels and will become the main source of energy for humanity**.

1. Science and technology news is the reporting of recent facts in the field of science and technology. The so-called facts of science and technology can be scientific and technological achievements and their popularization and application, the science and technology policies of the party and the state, the achievements of scientific and technological workers, and the activities of scientific and technological circles. These scientific and technological facts are reported and disseminated before they become scientific and technological news.

3. Science and technology news has the following characteristics:

1.News refers to the fact that the content of science and technology news should be new and the time is recent, and news is the main feature of science and technology news that distinguishes it from other science and technology styles.

2.Scientificity refers to the reporting and dissemination of scientific content in science and technology news, which is true, accurate, and scientifically based. At the same time, when reporting and disseminating scientific facts, attention should be paid to popularizing scientific knowledge among the broad masses of readers. Scientificity is what distinguishes science and technology journalism from other news genres.

3.Popularity, refers to the application of certain popular science writing skills when writing science and technology news, the language should be vivid, clever use of metaphors and explanations, and some background materials can be inserted to facilitate the acceptance and understanding of the majority of readers.

Fourth, the main role of science and technology news is to disseminate science and technology news in a timely manner and promote scientific and technological exchanges; At the same time, through science and technology news reports, publicize the party's and the state's science and technology policies, publicize advanced science and technology, and promote the transformation of science and technology into real productive forces. In addition, through science and technology news, scientific knowledge can be popularized among the public and the building of socialist material and spiritual civilization can be promoted.

From the point of view of the news itself, most of the news from the internal science and education department is science and technology news, and from the reader's point of view, the news that reports scientific research achievements, scientific research figures and scientific and technological development events belong to science and technology news.

The top 10 science news events must meet the following three criteria: a major breakthrough in a field that promotes the development of a related field, rather than a small improvement in existing research; A major scientific event that has attracted widespread attention and is of milestone significance; Major discoveries in a particular area will change existing understandings.

Scientific and technological innovation.

Construction waste is turned into concrete perforated bricks.

Concrete perforated bricks are a product that fills in the gaps. The production of such products can not only dispose of part of the urban construction waste, but also reduce a little environmental pollution; At the same time, it can replace a part of KP1 clay perforated bricks, which plays a role in saving soil and saving energy and reducing greenhouse gas emissions; And in the production of clay porous bricks, sometimes affected by the weather, can not be produced normally, and the use of construction waste to produce concrete porous bricks is not affected by this factor, so it can be used to regulate the role of the market to calm the world.

Construction waste slag concrete porous brick is a kind of concrete product that is made of construction waste slag as raw material, crushed and screened as aggregate, added to cement, additives and other admixtures, mixed with water, and vibrated by the molding machine. Among them, it should be noted that:

The screening process is done to create the best gradation; The proportion of sintered clay products and concrete components in the material mainly depends on the strength, and under normal circumstances, a certain proportion of sintered clay products should be mixed to improve the physical properties of the products, but the strength will be affected if the amount is too large; The hole brick should be made of semi-blind hole structure, which has certain benefits in construction, mechanical properties and physical properties.

In general, the construction waste slag concrete porous brick is mainly used for load-bearing structures, and its strength grade should be taken from the economic point of view, and the perforated bricks higher than MU10 can be produced but not economical, from this point of view, the concrete porous bricks are suitable for the mixed structure below six floors; At the same time, it can be used instead of KM type clay sintered hollow bricks for frame infill walls, and construction waste slag concrete bricks are used.

Rural buildings with less than three or four floors.
