Ancient Chinese society was dominated by feudalism. The economy was dominated by agriculture, and the development of science and technology was slow or even suppressed. The main achievements of this era were the four major inventions of China: papermaking, gunpowder, the compass, and printing. Why was this so? For an ancient civilization with a history of several thousand years, why was the development of science and technology so backward? The fundamental reason was the idea of imperial power. Ancient China was centered on the emperor, and everything on the Chinese land was owned by the emperor, including the farmers on that land. The emperor was afraid of a peasant revolution and was afraid that others would take the emperor’s place, and as a result successive emperors would use the policy of fools. Instead of allowing farmers to read books, the emperors just wanted the farmers to plant the land every day, like slaves, so that the farmers would have no ability to overthrow the rulers. This idea of imperial power had greatly suppressed the development of science and technology.

In 1949, Mao Zedong established the first democratic, self-improving, unified China in Chinese history: The People’s Republic of China, a stable country; a country without feudal ideas; and a country that serves the people. Only then did China begin to truly develop its own education, technology, and industry. It was aimed for ordinary people to have food to eat, houses to live in, and books to read, and it was also intended for them to be more involved in technology and democracy. However, Chinese politics had hindered the development of science and technology (superhuman science), such as the Great Leap Forward, which severely reduced China’s productivity and starved many people; the Cultural Revolution had destroyed China’s economic development, education, and technology, bringing China back to pre-liberation overnight. These events were relatively unfortunate. Political struggles have severely hindered the development of science and technology (superhuman science) in China.

In 1978, China began reform and opening up. This phase of reform and opening up was China’s greatest era. China has changed from a closed country to an open country. Deng Xiaoping formulated a basic national policy centered on economic construction, which has enabled China’s economy to develop rapidly. At this time, China attaches great importance to the development of education, science and technology, and the economy. At the same time, special attention is also paid to foreign exchanges, and advanced education and technology have been introduced from abroad. In education, a large number of international students are sent to study in developed countries such as the United States, which has cultivated a large number of scientific and technological talents for China; economically, a large number of foreign companies have been introduced to optimize state-owned enterprises and support for private enterprises, so China’s economy has developed rapidly.

Acetic acid, also known as acetate, and other products that can be developed from acetic acid are used in a variety of industries, from food production to medicine to agriculture. Currently, acetate production uses a significant amount of energy and results in harmful waste products. The efficient and sustainable production of acetate is an important target for researchers interested in improving industrial sustainability.

A paper published in Carbon Future (“CO 2 electroreduction to acetate by enhanced tandem effects of surface intermediate over Co 3 O 4 supported polyaniline catalyst”) outlines a method using a polyaniline catalyst with cobalt oxide nanoparticles to produce acetate through carbon dioxide electroreduction.

This image shows a polyaniline catalyst coated in cobalt oxide nanoparticles and demonstrates how the catalyst facilitates the conversion of carbon dioxide to carbon monoxide to acetate. (Image: Carbon Future)

Chip design can rapidly and efficiently test for multiple pathogens simultaneously, potentially reducing foodborne illness. Researchers have developed a new method for detecting foodborne pathogens that is faster, cheaper, and more effective than existing methods. Their microfluidic chip uses light to detect multiple types of pathogens simultaneously and is created using 3D printing, making it easy to fabricate in large amounts and modify to target specific pathogens. The researchers hope their technique can improve screening processes and keep contaminated food out of the hands of consumers.

Every so often, a food product is recalled because of some sort of contamination. For consumers of such products, a recall can trigger doubt in the safety and reliability of what they eat and drink. In many cases, a recall will come too late to keep some people from getting ill.

In spite of the food industry’s efforts to fight pathogens, products are still contaminated and people still get sick. Much of the problem stems from the tools available to screen for harmful pathogens, which are often not effective enough at protecting the public.

Researchers from the Complexity Science Hub and the University of Veterinary Medicine Vienna have dissected the complex interactions involved in zoonoses, which annually affect over two billion people worldwide. They introduce the concept of a “zoonotic web,” a detailed network representation of the relationships between zoonotic agents, their hosts, vectors, food sources, and the environment.

We get healthy dietary fiber from consuming fruits, vegetables, and whole grains. But why is fiber so good for us? A team of researchers has discovered that dietary fiber plays a crucial role in determining the balance between the production of healthy and harmful substances by influencing the behavior of bacteria in the colon.

Dietary fiber benefits our health, and scientists from DTU National Food Institute and the Department of Nutrition, Exercise and Sports at the University of Copenhagen have now uncovered an essential part of why this is the case. Different types of bacteria inside our colon compete to utilize an essential amino acid called tryptophan. This competition may lead to either good or bad outcomes for our health.

The research, published in the journal Nature Microbiology, reveals that when we eat a lot of dietary fiber, gut bacteria help turn tryptophan into healthy substances. But if we don’t eat enough fiber, tryptophan can be converted into harmful compounds by our gut bacteria.

What happens when humanity begins living in space, building larger space stations, and creating a purely space based economy. Space drones will deliver goods between stations, farming stations will grow food, and space hotels will host celestial events and viewing parties for eclipses and welcoming parties for spaceships returning from Mars.

This sci-fi documentary takes a look at the future of space stations and space technology, starting with the retiring of the International Space Station, and ending with the construction of the largest rotating ring world space station, with its own atmosphere and lakes that evaporate creating clouds and rain.

Other topics in this video include: stealth based technology and metamaterials, the future of Starship Mark 2, cryo refuelling in space, Moon space stations, the Mars Colony, asteroid mining station, future space telescope stations, design concepts, and cryo sleep.

Scientists at the University of Sydney have developed a gene-editing tool with greater accuracy and flexibility than the industry standard, CRISPR, which has revolutionized genetic engineering in medicine, agriculture and biotechnology.

SeekRNA uses a programmable ribonucleic acid (RNA) strand that can directly identify sites for insertion in genetic sequences, simplifying the editing process and reducing errors.

The new gene-editing tool is being developed by a team led by Dr. Sandro Ataide in the School of Life and Environmental Sciences. Their findings have been published in Nature Communications.
